Findings from a Phase 1 dose escalation trial of ASTX030, an investigational combination of azacitidine and cedazuridine, were shared with attendees during an oral presentation. In addition, results of a real-world study comparing clinical outcomes with INQOVI (decitabine and cedazuridine) tablets, an oral hypomethylating agent (HMA), versus intravenous (IV) or subcutaneous (SC) decitabine and azacitidine, respectively, were shared in a poster presentation.

Azacitidine and decitabine are HMAs. Following oral administration, HMAs are rapidly degraded by cytidine deaminase, resulting in poor oral bioavailability. Cedazuridine is a cytidine deaminase inhibitor, with the potential to increase the bioavailability of HMAs.

"We’re pleased to join hematology scientific leaders at the ASH (Free ASH Whitepaper) meeting to share data on oral HMAs for patients living with complications from MDS," said Harold Keer, MD, PhD, Chief Medical Officer, Taiho Oncology. "When administered at home, HMAs such as ASTX030 and INQOVI may potentially reduce the toll of time toxicity many patients with cancer experience and may help them to manage this disease long-term as a chronic condition."

Oral Presentation: Results of Phase 1 Open-Label Dose Escalation and Expansion Trial of ASTX030 (Oral Azacitidine + Cedazuridine)

This Phase 1 trial aimed to determine the optimal dose and formulation of ASTX030 to achieve oral azacitidine area under the curve (AUC) exposures comparable to SC azacitidine.

The trial enrolled 88 patients with MDS and MDS/MPN overlap syndromes, including chronic myelomonocytic leukemia (CMML), who received a median of seven cycles of treatment with ASTX030. Six combinations of azacitidine (60–144 mg) and cedazuridine (20–100 mg) doses were evaluated in the dose escalation portion of the trial, and two ASTX030 dose combinations (136 mg of azacitidine with 20 mg of cedazuridine and 144 mg of azacitidine with 20 mg of cedazuridine) were evaluated in the dose-expansion portion.

Pharmacokinetic data showed that 20 mg of cedazuridine sufficiently prevented azacitidine from degradation during first pass in the digestive tract and liver resulting in enhanced azacitidine bioavailability, achieving AUC exposures comparable to SC azacitidine, and the dose combination of 140 mg azacitidine/20 mg cedazuridine was recommended for evaluation in Phase 2.

The clinical efficacy results were consistent with parenteral azacitidine. The median overall survival was 29.5 months, with overall response rate of 56% (11% complete response, 0% partial response, 34% marrow complete response, 10% hematologic improvement), 27% stable disease, 2% progressive disease and 15% not evaluable.

Treatment emergent adverse events (TEAEs) were reported in 100% of participants, with 86% experiencing an AE of grade 3 or higher and 9% discontinuing treatment due to an AE. The most common TEAEs of grade 3 or higher were related to myelosuppression. Gastrointestinal AEs also reflected a similar safety profile to that typically associated with SC azacitidine. There was one dose-limiting toxicity that was possibly related to the study drug — a case of prolonged grade 4 neutropenia.

"These results are promising, as they demonstrate the potential of this novel oral therapy to reduce the treatment burden for people with MDS," said Guillermo Garcia-Manero, MD, professor of Leukemia at The University of Texas MD Anderson Cancer Center and the study’s lead investigator. "We look forward to soon sharing the results of a recently completed Phase 2 study of ASTX030 and are planning a Phase 3 trial of the compound."

Real-World Use Patterns and Outcomes for MDS Patients Treated with INQOVI or IV/SC HMA

The real-world study evaluated HMAs use patterns and clinical outcomes in adults with MDS who received first-line treatment with either INQOVI or a similar HMA administered subcutaneously or intravenously. Real-world treatment outcomes among MDS patients were gathered through the ConcertAI real-world electronic health records database.

Of 2,101 enrolled patients, 405 were treated with INQOVI and 1,696 with IV or SC azacitidine or decitabine.

Patients receiving INQOVI had a numerically longer median real-world overall survival (rwOS) compared to those treated with IV/SC HMA (23.2 versus 19.0 months) and lower risk of death, although the differences were not statistically significant.

Notably, median acute myeloid leukemia (AML)-free survival was 16.5 months with INQOVI versus 13.3 months with IC/SC HMAs (p=0.009). Furthermore, in a Cox-adjusted model, patients treated with INQOVI had a 16% lower risk of AML transformation or death (HR=0.84; 95% CI: 0.73–0.98; p=0.027) compared with those treated with IV or SC HMAs.

Those who received INQOVI prolonged the time to next treatment: 9.4 months, versus 7.4 months for those in the IV/SC cohort (p<0.001). Patients who received INQOVI were 18% less likely than their study counterparts receiving IV/SC HMAs to receive a next treatment (HR=0.82; 95% CI: 0.71–0.94; p=0.004).

"This real-world study is among the first and largest to examine clinical outcomes in patients treated for MDS with either first-line INQOVI or an intravenous or subcutaneous hypomethylating agent," said Tehseen Salimi, MD, MHA, Senior Vice President and Head of Medical Affairs, Taiho Oncology. "In addition to demonstrating comparable overall survival between the two treatment options, this study identified some potentially exciting unique signals of efficacy in patients who took INQOVI. These results highlight the potential value of this compound as an alternative to parenteral hypomethylating agents."

INDICATIONS AND IMPORTANT SAFETY INFORMATION

INDICATIONS

Decitabine and cedazuridine, marketed under the brand name INQOVI, is indicated for treatment of adult patients with myelodysplastic syndromes (MDS), including previously treated and untreated, de novo and secondary MDS with the following French-American-British subtypes (refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with excess blasts, and chronic myelomonocytic leukemia [CMML]) and intermediate-1, intermediate-2, and high-risk International Prognostic Scoring System groups.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Myelosuppression: Fatal and serious myelosuppression can occur with INQOVI. Based on laboratory values, new or worsening thrombocytopenia occurred in 82% of patients, with Grade 3 or 4 occurring in 76%. Neutropenia occurred in 73% of patients, with Grade 3 or 4 occurring in 71%. Anemia occurred in 71% of patients, with Grade 3 or 4 occurring in 55%. Febrile neutropenia occurred in 33% of patients, with Grade 3 or 4 occurring in 32%. Myelosuppression (thrombocytopenia, neutropenia, anemia, and febrile neutropenia) is the most frequent cause of INQOVI dose reduction or interruption, occurring in 36% of patients. Permanent discontinuation due to myelosuppression (febrile neutropenia) occurred in 1% of patients. Myelosuppression and worsening neutropenia may occur more frequently in the first or second treatment cycles and may not necessarily indicate progression of underlying MDS.

Fatal and serious infectious complications can occur with INQOVI. Pneumonia occurred in 21% of patients, with Grade 3 or 4 occurring in 15%. Sepsis occurred in 14% of patients, with Grade 3 or 4 occurring in 11%. Fatal pneumonia occurred in 1% of patients, fatal sepsis in 1%, and fatal septic shock in 1%.

Obtain complete blood cell counts prior to initiation of INQOVI, prior to each cycle, and as clinically indicated to monitor response and toxicity. Administer growth factors and anti-infective therapies for treatment or prophylaxis as appropriate. Delay the next cycle and resume at the same or reduced dose as recommended.

Embryo-Fetal Toxicity: INQOVI can cause fetal harm. Advise pregnant women of the potential risk to a fetus. Advise patients to use effective contraception during treatment and for 6 months (females) or 3 months (males) after last dose.

ADVERSE REACTIONS

Serious adverse reactions in > 5% of patients included febrile neutropenia (30%), pneumonia (14%), and sepsis (13%). Fatal adverse reactions included sepsis (1%), septic shock (1%), pneumonia (1%), respiratory failure (1%), and one case each of cerebral hemorrhage and sudden death.

The most common adverse reactions (≥ 20%) were fatigue (55%), constipation (44%), hemorrhage (43%), myalgia (42%), mucositis (41%), arthralgia (40%), nausea (40%), dyspnea (38%), diarrhea (37%), rash (33%), dizziness (33%), febrile neutropenia (33%), edema (30%), headache (30%), cough (28%), decreased appetite (24%), upper respiratory tract infection (23%), pneumonia (21%), and transaminase increased (21%). The most common Grade 3 or 4 laboratory abnormalities (≥ 50%) were leukocytes decreased (81%), platelet count decreased (76%), neutrophil count decreased (71%), and hemoglobin decreased (55%).

USE IN SPECIFIC POPULATIONS

Lactation: Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with INQOVI and for 2 weeks after the last dose.

Renal Impairment: No dosage modification of INQOVI is recommended for patients with mild or moderate renal impairment (creatinine clearance [CLcr] of 30 to 89 mL/min based on Cockcroft-Gault). Due to the potential for increased adverse reactions, monitor patients with moderate renal impairment (CLcr 30 to 59 mL/min) frequently for adverse reactions. INQOVI has not been studied in patients with severe renal impairment (CLcr 15 to 29 mL/min) or end-stage renal disease (ESRD: CLcr <15 mL/min).

CARVYKTI® (ciltacabtagene autoleucel) demonstrated significantly higher rates of minimal residual disease (MRD) negativity compared to standard therapies in the CARTITUDE-4 study

On December 9, 2024 Johnson & Johnson (NYSE:JNJ) reported new results from the Phase 3 CARTITUDE-4 study that show a single infusion of CARVYKTI (ciltacabtagene autoleucel; cilta-cel) significantly increased minimal residual disease (MRD) negativity rates (10-5) in patients with relapsed or refractory multiple myeloma (RRMM) who were lenalidomide-refractory and had received one to three prior lines of therapy, including a proteasome inhibitor (PI), compared to standard therapies of pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd) (Press release, Johnson & Johnson, DEC 9, 2024, View Source [SID1234648933]). MRD is a prognostic marker of prolonged survival outcomes for patients with multiple myeloma. These results add to the overall survival (OS) benefits recently presented at the International Myeloma Society meeting earlier this year, as the first and only cell therapy to significantly extend OS versus standard therapies for patients with multiple myeloma.1 Findings were featured in an oral presentation at the 2024 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Abstract #1032).1

"CARVYKTI has established its significant impact on overall survival and improved progression-free survival compared to standard therapies," said Rakesh Popat, M.D., University College London Hospitals, NHS Foundation Trust, London, UK, and lead study investigator.* "The MRD negativity results demonstrate deep responses compared to standard therapies for people living with multiple myeloma and further underscore the benefit of CARVYKTI, administered as a single infusion as early as second line."

The Phase 3 CARTITUDE-4 study evaluated CARVYKTI compared to standard therapies of PVd or DPd for the treatment of patients with RRMM as early as after one prior line of therapy.1 Patients who received one to three prior lines of therapy, including a PI and immunomodulatory agent (IMiD), and were lenalidomide-refractory, were randomized (CARVYKTI, n=208, standard therapies, n=211).1 At a median follow-up of almost three years (34 months), MRD-negativity rates for evaluable patients were more than double in those treated with CARVYKTI versus standard therapies (89 percent, 38 percent; P<0.0001).1 At 2.5 years, sustained (12 months or more), MRD-negative complete response or better in evaluable patients treated with CARVYKTI was five-fold higher than that of standard therapies (52 percent, 10 percent; P<0.0001). A post-hoc comparison between CARTITUDE-4 and CARTITUDE-1 was also presented, comparing earlier treatment (1-3 versus 3+ prior lines of therapy) demonstrating higher rates of MRD negativity, progression-free survival (PFS) and OS rates when CARVYKTI is used earlier in treatment.

"We are thrilled to present the latest MRD negativity results from the CARTITUDE-4 study showing that CARVYKTI, the first and only cell therapy approved for the treatment of patients with multiple myeloma as early as second line, shows profound long-term remission rates, including progression-free survival and overall survival benefits," said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, Johnson & Johnson Innovative Medicine. "It is also increasingly clear that reaching MRD negativity is a key goal with CAR-T therapy in myeloma, and we see that MRD rates were higher in this analysis with earlier treatment."

Additional data on patient reported outcomes (PROs) and time to worsening (TTW) of symptoms with CARVYKTI will also be presented at ASH (Free ASH Whitepaper) 2024 as a poster presentation (Abstract #2002).2 Based on the Multiple Myeloma Symptom and Impact Questionnaire (MySlm-Q) system and impact domain scores, patients treated with CARVYKTI reported significantly longer TTW of symptoms compared to standard therapies.2 At three-year follow up, 83 percent of patients treated with CARVYKTI had not experienced worsening of functional impacts, compared to 69 percent in the standard therapies arm.2

About CARTITUDE-4

CARTITUDE-4 (NCT04181827) is the first randomized Phase 3 study evaluating the efficacy and safety of CARVYKTI. The study compares CARVYKTI with standard of care treatments PVd or DPd in adult patients with relapsed and lenalidomide-refractory multiple myeloma who received one to three prior lines of therapy. The primary endpoint of the study is PFS; safety, OS, MRD negativity rate and overall response rate are secondary endpoints.

About CARVYKTI (ciltacabtagene autoleucel; cilta-cel)

CARVYKTI is a BCMA-directed, genetically modified autologous T-cell immunotherapy that involves reprogramming a patient’s own T-cells with a transgene encoding chimeric antigen receptor (CAR) that directs the CAR-positive T cells to eliminate cells that express BCMA. BCMA is primarily expressed on the surface of malignant multiple myeloma B-lineage cells, as well as late-stage B cells and plasma cells. The CARVYKTI CAR protein features two BCMA-targeting single domains designed to confer high avidity against human BCMA. Upon binding to BCMA-expressing cells, the CAR promotes T-cell activation, expansion, and elimination of target cells.

CARVYKTI (cilta-cel) received U.S. Food and Drug Administration approval in February 2022 for the treatment of adults with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. In April 2024, CARVYKTI was approved as the first and only cell therapy in the U.S. for treatment of adult patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy including a proteasome inhibitor, an immunomodulatory agent, and who are refractory to lenalidomide. In April 2024, the European Medicines Agency (EMA) approved a Type II variation for CARVYKTI for the treatment of adults with relapsed and refractory multiple myeloma who have received at least one prior therapy, including an immunomodulatory agent and a proteasome inhibitor, have demonstrated disease progression on the last therapy, and are refractory to lenalidomide.

In December 2017, Janssen Biotech, Inc., a Johnson & Johnson company, entered into an exclusive worldwide license and collaboration agreement with Legend Biotech USA, Inc. to develop and commercialize CARVYKTI.

About Multiple Myeloma

Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.3 In multiple myeloma, these plasma cells proliferate and spread rapidly and replace normal cells in the bone marrow with tumors.4 Multiple myeloma is the third most common blood cancer worldwide and remains an incurable disease.5 In 2024, it was estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 people would die from the disease.6 People living with multiple myeloma have a 5-year survival rate of 59.8 percent.7 While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels and kidney problems or infections.8,9

CARVYKTI IMPORTANT SAFETY INFORMATION

INDICATIONS AND USAGE

CARVYKTI (ciltacabtagene autoleucel) is a B-cell maturation antigen (BCMA)-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adult patients with relapsed or refractory multiple myeloma, who have received at least 1 prior line of therapy, including a proteasome inhibitor and an immunomodulatory agent, and are refractory to lenalidomide.

IMPORTANT SAFETY INFORMATION

WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, HLH/MAS, PROLONGED and RECURRENT CYTOPENIA, and SECONDARY HEMATOLOGICAL MALIGNANCIES

Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients following treatment with CARVYKTI. Do not administer CARVYKTI to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.

Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS), which may be fatal or life-threatening, occurred following treatment with CARVYKTI, including before CRS onset, concurrently with CRS, after CRS resolution, or in the absence of CRS. Monitor for neurologic events after treatment with CARVYKTI. Provide supportive care and/or corticosteroids as needed.

Parkinsonism and Guillain-Barré syndrome (GBS) and their associated complications resulting in fatal or life-threatening reactions have occurred following treatment with CARVYKTI.

Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome (HLH/MAS), including fatal and life-threatening reactions, occurred in patients following treatment with CARVYKTI. HLH/MAS can occur with CRS or neurologic toxicities.

Prolonged and/or recurrent cytopenias with bleeding and infection and requirement for stem cell transplantation for hematopoietic recovery occurred following treatment with CARVYKTI.

Secondary hematological malignancies, including myelodysplastic syndrome and acute myeloid leukemia, have occurred in patients following treatment with CARVYKTI. T-cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies, including CARVYKTI.

CARVYKTI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the CARVYKTI REMS Program.

WARNINGS AND PRECAUTIONS

Increased early mortality – In CARTITUDE-4, a (1:1) randomized controlled trial, there was a numerically higher percentage of early deaths in patients randomized to the CARVYKTI treatment arm compared to the control arm. Among patients with deaths occurring within the first 10 months from randomization, a greater proportion (29/208; 14%) occurred in the CARVYKTI arm compared to (25/211; 12%) in the control arm. Of the 29 deaths that occurred in the CARVYKTI arm within the first 10 months of randomization, 10 deaths occurred prior to CARVYKTI infusion, and 19 deaths occurred after CARVYKTI infusion. Of the 10 deaths that occurred prior to CARVYKTI infusion, all occurred due to disease progression, and none occurred due to adverse events. Of the 19 deaths that occurred after CARVYKTI infusion, 3 occurred due to disease progression, and 16 occurred due to adverse events. The most common adverse events were due to infection (n=12).

Cytokine release syndrome (CRS), including fatal or life-threatening reactions, occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI for RRMM in the CARTITUDE-1 & 4 studies (N=285), CRS occurred in 84% (238/285), including ≥Grade 3 CRS (ASCT 2019) in 4% (11/285) of patients. Median time to onset of CRS, any grade, was 7 days (range: 1 to 23 days). CRS resolved in 82% with a median duration of 4 days (range: 1 to 97 days). The most common manifestations of CRS in all patients combined (≥10%) included fever (84%), hypotension (29%) and aspartate aminotransferase increased (11%). Serious events that may be associated with CRS include pyrexia, hemophagocytic lymphohistiocytosis, respiratory failure, disseminated intravascular coagulation, capillary leak syndrome, and supraventricular and ventricular tachycardia. CRS occurred in 78% of patients in CARTITUDE-4 (3% Grade 3 to 4) and in 95% of patients in CARTITUDE-1 (4% Grade 3 to 4).

Identify CRS based on clinical presentation. Evaluate for and treat other causes of fever, hypoxia, and hypotension. CRS has been reported to be associated with findings of HLH/MAS, and the physiology of the syndromes may overlap. HLH/MAS is a potentially life-threatening condition. In patients with progressive symptoms of CRS or refractory CRS despite treatment, evaluate for evidence of HLH/MAS.

Ensure that a minimum of two doses of tocilizumab are available prior to infusion of CARVYKTI.

Of the 285 patients who received CARVYKTI in clinical trials, 53% (150/285) patients received tocilizumab; 35% (100/285) received a single dose, while 18% (50/285) received more than 1 dose of tocilizumab. Overall, 14% (39/285) of patients received at least one dose of corticosteroids for treatment of CRS.

Monitor patients at least daily for 10 days following CARVYKTI infusion at a REMS-certified healthcare facility for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for at least 4 weeks after infusion. At the first sign of CRS, immediately institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids.

Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time.

Neurologic toxicities, which may be severe, life-threatening, or fatal, occurred following treatment with CARVYKTI. Neurologic toxicities included ICANS, neurologic toxicity with signs and symptoms of parkinsonism, GBS, immune mediated myelitis, peripheral neuropathies, and cranial nerve palsies. Counsel patients on the signs and symptoms of these neurologic toxicities, and on the delayed nature of onset of some of these toxicities. Instruct patients to seek immediate medical attention for further assessment and management if signs or symptoms of any of these neurologic toxicities occur at any time.

Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies for RRMM, one or more neurologic toxicities occurred in 24% (69/285), including ≥Grade 3 cases in 7% (19/285) of patients. Median time to onset was 10 days (range: 1 to 101) with 63/69 (91%) of cases developing by 30 days. Neurologic toxicities resolved in 72% (50/69) of patients with a median duration to resolution of 23 days (range: 1 to 544). Of patients developing neurotoxicity, 96% (66/69) also developed CRS. Subtypes of neurologic toxicities included ICANS in 13%, peripheral neuropathy in 7%, cranial nerve palsy in 7%, parkinsonism in 3%, and immune mediated myelitis in 0.4% of the patients.

Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS): Patients receiving CARVYKTI may experience fatal or life-threatening ICANS following treatment with CARVYKTI, including before CRS onset, concurrently with CRS, after CRS resolution, or in the absence of CRS.

Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, ICANS occurred in 13% (36/285), including Grade ≥3 in 2% (6/285) of the patients. Median time to onset of ICANS was 8 days (range: 1 to 28 days). ICANS resolved in 30 of 36 (83%) of patients with a median time to resolution of 3 days (range: 1 to 143 days). Median duration of ICANS was 6 days (range: 1 to 1229 days) in all patients including those with ongoing neurologic events at the time of death or data cut off. Of patients with ICANS 97% (35/36) had CRS. The onset of ICANS occurred during CRS in 69% of patients, before and after the onset of CRS in 14% of patients respectively.

Immune Effector Cell-associated Neurotoxicity Syndrome occurred in 7% of patients in CARTITUDE-4 (0.5% Grade 3) and in 23% of patients in CARTITUDE-1 (3% Grade 3). The most frequent ≥2% manifestations of ICANS included encephalopathy (12%), aphasia (4%), headache (3%), motor dysfunction (3%), ataxia (2%) and sleep disorder (2%).

Monitor patients at least daily for 10 days following CARVYKTI infusion at the REMS-certified healthcare facility for signs and symptoms of ICANS. Rule out other causes of ICANS symptoms. Monitor patients for signs or symptoms of ICANS for at least 4 weeks after infusion and treat promptly. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed.

Parkinsonism: Neurologic toxicity with parkinsonism has been reported in clinical trials of CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, parkinsonism occurred in 3% (8/285), including Grade ≥ 3 in 2% (5/285) of the patients. Median time to onset of parkinsonism was 56 days (range: 14 to 914 days). Parkinsonism resolved in 1 of 8 (13%) of patients with a median time to resolution of 523 days. Median duration of parkinsonism was 243.5 days (range: 62 to 720 days) in all patients including those with ongoing neurologic events at the time of death or data cut off. The onset of parkinsonism occurred after CRS for all patients and after ICANS for 6 patients.

Parkinsonism occurred in 1% of patients in CARTITUDE-4 (no Grade 3 to 4) and in 6% of patients in CARTITUDE-1 (4% Grade 3 to 4).

Manifestations of parkinsonism included movement disorders, cognitive impairment, and personality changes. Monitor patients for signs and symptoms of parkinsonism that may be delayed in onset and managed with supportive care measures. There is limited efficacy information with medications used for the treatment of Parkinson’s disease for the improvement or resolution of parkinsonism symptoms following CARVYKTI treatment.

Guillain-Barré syndrome: A fatal outcome following GBS occurred following treatment with CARVYKTI despite treatment with intravenous immunoglobulins. Symptoms reported include those consistent with Miller-Fisher variant of GBS, encephalopathy, motor weakness, speech disturbances, and polyradiculoneuritis.

Monitor for GBS. Evaluate patients presenting with peripheral neuropathy for GBS. Consider treatment of GBS with supportive care measures and in conjunction with immunoglobulins and plasma exchange, depending on severity of GBS.

Immune mediated myelitis: Grade 3 myelitis occurred 25 days following treatment with CARVYKTI in CARTITUDE-4 in a patient who received CARVYKTI as subsequent therapy. Symptoms reported included hypoesthesia of the lower extremities and the lower abdomen with impaired sphincter control. Symptoms improved with the use of corticosteroids and intravenous immune globulin. Myelitis was ongoing at the time of death from other cause.

Peripheral neuropathy occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, peripheral neuropathy occurred in 7% (21/285), including Grade ≥3 in 1% (3/285) of the patients. Median time to onset of peripheral neuropathy was 57 days (range: 1 to 914 days). Peripheral neuropathy resolved in 11 of 21 (52%) of patients with a median time to resolution of 58 days (range: 1 to 215 days). Median duration of peripheral neuropathy was 149.5 days (range: 1 to 692 days) in all patients including those with ongoing neurologic events at the time of death or data cut off.

Peripheral neuropathies occurred in 7% of patients in CARTITUDE-4 (0.5% Grade 3 to 4) and in 7% of patients in CARTITUDE-1 (2% Grade 3 to 4). Monitor patients for signs and symptoms of peripheral neuropathies. Patients who experience peripheral neuropathy may also experience cranial nerve palsies or GBS.

Cranial nerve palsies occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, cranial nerve palsies occurred in 7% (19/285), including Grade ≥3 in 1% (1/285) of the patients. Median time to onset of cranial nerve palsies was 21 days (range: 17 to 101 days). Cranial nerve palsies resolved in 17 of 19 (89%) of patients with a median time to resolution of 66 days (range: 1 to 209 days). Median duration of cranial nerve palsies was 70 days (range: 1 to 262 days) in all patients including those with ongoing neurologic events at the time of death or data cut off. Cranial nerve palsies occurred in 9% of patients in CARTITUDE-4 (1% Grade 3 to 4) and in 3% of patients in CARTITUDE-1 (1% Grade 3 to 4).

The most frequent cranial nerve affected was the 7th cranial nerve. Additionally, cranial nerves III, V, and VI have been reported to be affected.

Monitor patients for signs and symptoms of cranial nerve palsies. Consider management with systemic corticosteroids, depending on the severity and progression of signs and symptoms.

Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (MAS): Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, HLH/MAS occurred in 1% (3/285) of patients. All events of HLH/MAS had onset within 99 days of receiving CARVYKTI, with a median onset of 10 days (range: 8 to 99 days) and all occurred in the setting of ongoing or worsening CRS. The manifestations of HLH/MAS included hyperferritinemia, hypotension, hypoxia with diffuse alveolar damage, coagulopathy and hemorrhage, cytopenia and multi-organ dysfunction, including renal dysfunction and respiratory failure.

Patients who develop HLH/MAS have an increased risk of severe bleeding. Monitor hematologic parameters in patients with HLH/MAS and transfuse per institutional guidelines. Fatal cases of HLH/MAS occurred following treatment with CARVYKTI.

HLH is a life-threatening condition with a high mortality rate if not recognized and treated early. Treatment of HLH/MAS should be administered per institutional standards.

CARVYKTI REMS: Because of the risk of CRS and neurologic toxicities, CARVYKTI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the CARVYKTI REMS.

Further information is available at View Source or 1-844-672-0067.

Prolonged and Recurrent Cytopenias: Patients may exhibit prolonged and recurrent cytopenias following lymphodepleting chemotherapy and CARVYKTI infusion.

Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, Grade 3 or higher cytopenias not resolved by day 30 following CARVYKTI infusion occurred in 62% (176/285) of the patients and included thrombocytopenia 33% (94/285), neutropenia 27% (76/285), lymphopenia 24% (67/285) and anemia 2% (6/285). After Day 60 following CARVYKTI infusion 22%, 20%, 5%, and 6% of patients had a recurrence of Grade 3 or 4 lymphopenia, neutropenia, thrombocytopenia, and anemia respectively, after initial recovery of their Grade 3 or 4 cytopenia. Seventy-seven percent (219/285) of patients had one, two or three or more recurrences of Grade 3 or 4 cytopenias after initial recovery of Grade 3 or 4 cytopenia. Sixteen and 25 patients had Grade 3 or 4 neutropenia and thrombocytopenia, respectively, at the time of death.

Monitor blood counts prior to and after CARVYKTI infusion. Manage cytopenias with growth factors and blood product transfusion support according to local institutional guidelines.

Infections: CARVYKTI should not be administered to patients with active infection or inflammatory disorders. Severe, life-threatening, or fatal infections, occurred in patients after CARVYKTI infusion.

Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, infections occurred in 57% (163/285), including ≥Grade 3 in 24% (69/285) of patients. Grade 3 or 4 infections with an unspecified pathogen occurred in 12%, viral infections in 6%, bacterial infections in 5%, and fungal infections in 1% of patients. Overall, 5% (13/285) of patients had Grade 5 infections, 2.5% of which were due to COVID-19. Patients treated with CARVYKTI had an increased rate of fatal COVID-19 infections compared to the standard therapy arm.

Monitor patients for signs and symptoms of infection before and after CARVYKTI infusion and treat patients appropriately. Administer prophylactic, pre-emptive and/or therapeutic antimicrobials according to the standard institutional guidelines. Febrile neutropenia was observed in 5% of patients after CARVYKTI infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids and other supportive care, as medically indicated. Counsel patients on the importance of prevention measures. Follow institutional guidelines for the vaccination and management of immunocompromised patients with COVID-19.

Viral Reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure and death, can occur in patients with hypogammaglobulinemia. Perform screening for Cytomegalovirus (CMV), HBV, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) or any other infectious agents if clinically indicated in accordance with clinical guidelines before collection of cells for manufacturing. Consider antiviral therapy to prevent viral reactivation per local institutional guidelines/clinical practice.

Hypogammaglobulinemia: can occur in patients receiving treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, hypogammaglobulinemia adverse event was reported in 36% (102/285) of patients; laboratory IgG levels fell below 500mg/dl after infusion in 93% (265/285) of patients. Hypogammaglobulinemia either as an adverse reaction or laboratory IgG level below 500mg/dl, after infusion occurred in 94% (267/285) of patients treated. Fifty six percent (161/285) of patients received intravenous immunoglobulin (IVIG) post CARVYKTI for either an adverse reaction or prophylaxis.

Monitor immunoglobulin levels after treatment with CARVYKTI and administer IVIG for IgG <400 mg/dL. Manage per local institutional guidelines, including infection precautions and antibiotic or antiviral prophylaxis.

Use of Live Vaccines: The safety of immunization with live viral vaccines during or following CARVYKTI treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during CARVYKTI treatment, and until immune recovery following treatment with CARVYKTI.

Hypersensitivity Reactions occurred following treatment with CARVYKTI. Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, hypersensitivity reactions occurred in 5% (13/285), all of which were ≤Grade 2. Manifestations of hypersensitivity reactions included flushing, chest discomfort, tachycardia, wheezing, tremor, burning sensation, non-cardiac chest pain, and pyrexia.

Serious hypersensitivity reactions, including anaphylaxis, may be due to the dimethyl sulfoxide (DMSO) in CARVYKTI. Patients should be carefully monitored for 2 hours after infusion for signs and symptoms of severe reaction. Treat promptly and manage patients appropriately according to the severity of the hypersensitivity reaction.

Secondary Malignancies: Patients treated with CARVYKTI may develop secondary malignancies. Among patients receiving CARVYKTI in the CARTITUDE-1 & 4 studies, myeloid neoplasms occurred in 5% (13/285) of patients (9 cases of myelodysplastic syndrome, 3 cases of acute myeloid leukemia, and 1 case of myelodysplastic syndrome followed by acute myeloid leukemia). The median time to onset of myeloid neoplasms was 447 days (range: 56 to 870 days) after treatment with CARVYKTI. Ten of these 13 patients died following the development of myeloid neoplasms; 2 of the 13 cases of myeloid neoplasm occurred after initiation of subsequent antimyeloma therapy. Cases of myelodysplastic syndrome and acute myeloid leukemia have also been reported in the post marketing setting. T-cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies, including CARVYKTI. Mature T-cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusions, and may include fatal outcomes.

Monitor life-long for secondary malignancies. In the event that a secondary malignancy occurs, contact Janssen Biotech, Inc. at 1-800-526-7736 for reporting and to obtain instructions on collection of patient samples.

Effects on Ability to Drive and Use Machines: Due to the potential for neurologic events, including altered mental status, seizures, neurocognitive decline or neuropathy, patients receiving CARVYKTI are at risk for altered or decreased consciousness or coordination in the 8 weeks following CARVYKTI infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery during this initial period, and in the event of new onset of any neurologic toxicities.

ADVERSE REACTIONS

The most common nonlaboratory adverse reactions (incidence greater than 20%) are pyrexia, cytokine release syndrome, hypogammaglobulinemia, hypotension, musculoskeletal pain, fatigue, infections-pathogen unspecified, cough, chills, diarrhea, nausea, encephalopathy, decreased appetite, upper respiratory tract infection, headache, tachycardia, dizziness, dyspnea, edema, viral infections, coagulopathy, constipation, and vomiting. The most common Grade 3 or 4 laboratory adverse reactions (incidence greater than or equal to 50%) include lymphopenia, neutropenia, white blood cell decreased, thrombocytopenia, and anemia.

"Our oral presentation at ASH (Free ASH Whitepaper) this year with data from the FELIX trial demonstrates that obe-cel treatment produces a high incidence of deep molecular remission in r/r adult ALL patients, which correlates with better outcomes and is associated with longer event free survival (EFS) and overall survival (OS)," said Dr. Christian Itin, Chief Executive Officer of Autolus. "We’re also presenting three posters that aim to further our understanding of the use of obe-cel in a real-world context, suggesting the positive clinical outcomes of obe-cel even after effective bridging therapy; the reduced healthcare resource utilization costs associated with lower severity of ICANS and CRS; and how hematotoxicity scores could help identify patients who are at higher risk for hematotoxicity from treatment with obe-cel."

Summary: Obe-cel treatment produces a high incidence of deep remission, which is predictive of better clinical outcomes. The majority of responders to obe-cel achieved deep remission to MRD <10–6 level (84%, 57/68), measured by clonoSEQ NGS assay. Deep MRD remission correlates with better outcomes and is associated with longer event free survival (EFS) and overall survival (OS). The largest EFS and OS benefit was seen with lower tumor burden at lymphodepletion.

Summary: Comparable expansion and long-term persistence of obe-cel was observed with all the bridging therapies evaluated, suggesting that long-term persistence of obe-cel is possible irrespective of the bridging therapy and independent of disease burden at lymphodepletion. Bridging therapy with inotuzumab ozogamicin was effective in reducing disease burden prior to lymphodepletion and obe-cel infusion. Reduction in disease burden at lymphodepletion through bridging therapy led to improved event-free survival and overall survival compared to bridging therapy without INO and maintained a tolerable safety profile.

Summary: Grade ≥3 cytokine release syndrome (CRS) and/or immune effector cell-associated neurotoxicity syndrome (ICANS) are associated with increased healthcare resource utilization (HCRU) and costs, but these events were rare in the FELIX study. Costs for adverse events generally increase with event severity. Medication usage and intensive care unit costs were key drivers of CRS and/or ICANS management costs. Obe-cel has the potential to optimize utilization of resources and reduce costs associated with CAR T-cell therapy for patients with R/R B-ALL as a result of the low incidence of Grade ≥3 CRS and/or ICANS.

Summary: The CAR-HEMATOTOX risk score correlated with disease burden in this patient population – patients with high-risk CAR-HEMATOTOX scores had consistently worse outcomes than patients with low-risk CAR-HEMATOTOX scores. Risk-stratification, using pre-lymphodepletion clinical parameters together with disease burden, has the potential to be a useful tool for identifying patients at a high risk for hematotoxicity who may benefit from obe-cel treatment.

BeiGene Advances Leadership in CLL at ASH 2024 with New Data From Its Hematology Franchise Including BRUKINSA® and Novel Pipeline Assets

On December 9, 2024 BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global oncology company that plans to change its name to BeOne Medicines Ltd., reported the presentation of new clinical data at the 66th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition, underscoring its leadership in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) through continued clinical success with BRUKINSA (zanubrutinib) and promising advancements in its pipeline assets (Press release, BeiGene, DEC 9, 2024, View Source [SID1234648931]).

"The breadth of data we’re presenting at ASH (Free ASH Whitepaper) underscores BRUKINSA’s role as a best-in-class treatment for CLL and highlights BeiGene’s leadership in advancing the treatment landscape for B-cell malignancies," said Mehrdad Mobasher, M.D., M.P.H., Chief Medical Officer, Hematology at BeiGene. "BRUKINSA shows tremendous promise for patients as a monotherapy and as a backbone for best-in-class combinations. The combination of BRUKINSA and our investigational BCL2 inhibitor, sonrotoclax, demonstrated significant potential as a first-line therapy in CLL, with a 99% overall response rate, best uMRD rate of 92%, and was generally well-tolerated at a median follow-up of 19.4 months; this combination is expected to offer better efficacy than a fixed-dose V-O regimen. Additionally, our investigational BTK degrader could become a first-in-class treatment option for patients with CLL and other BTK-driven B-cell malignancies based on the results of data presented at ASH (Free ASH Whitepaper). BeiGene is primed to shape the future of CLL treatment and aims to meet the needs of CLL patients globally."

Long-term follow-up results from the ongoing Phase 3 SEQUOIA study presented during ASH (Free ASH Whitepaper), which were simultaneously published in the Journal of Clinical Oncology, reaffirm BRUKINSA’s durable efficacy and differentiated safety profile across diverse CLL patient populations, including those with high-risk features. Additional findings spotlight the promising potential of BeiGene’s BTK-targeted chimeric degradation activation compound (CDAC), BGB-16673, which has shown rapid and deep responses in B-cell malignancies in phase 1/2 clinical trials. BeiGene is also developing a next-generation BCL2 inhibitor, sonrotoclax, aiming to improve the safety profile and feasibility of use for this class of drugs and deliver deeper and more durable responses. Together, these advancements reflect BeiGene’s comprehensive approach to addressing the complexities of CLL and its commitment to reshaping the treatment landscape for B-cell malignancies.

With a median follow-up of 61.2 months, data from the SEQUOIA study of patients with treatment-naïve CLL/SLL demonstrated that treatment with BRUKINSA reduced the risk of progression or death by 71% (HR, 0.29; 95% CI, 0.21-0.40; P<.0001*) compared to bendamustine-rituximab (BR). At 54 months, 80.1% of patients who received BRUKINSA remained progression-free (95% CI, 74.3, 84.7) while only 44.6% of patients who received BR remained progression-free (95% CI, 37.6, 51.3). At 60 months, PFS rates were 75.8% (95% CI, 69.0, 81.3) and 40.1% (95% CI, 32.7, 47.3) for BRUKINSA and BR, respectively. Notably, for patients in the study with unmutated IGHV, a prognostic biomarker that indicates a patient’s CLL may be more aggressive, treatment with BRUKINSA reduced the risk of progression or death by 79% compared to BR (HR, 0.21; 95% CI, 0.14-0.33; P<.0001*). The safety profile of BRUKINSA was consistent with the results of prior studies, and no new safety signals were identified. Grade ≥3 treatment-emergent adverse events of interest (AEIs) with BRUKINSA and BR included infection (30.0% and 22.5%, respectively), neutropenia (12.5%; 51.1%), bleeding (7.5%; 1.8%), thrombocytopenia (2.5%; 8.4%), and anemia (0.8%; 2.6%). Rates of atrial fibrillation were 7.1% with BRUKINSA and 3.5% with BR. The rate of discontinuation due to AEs was 20% in the BRUKINSA arm; 13% of patients discontinued BR early due AEs.(Abstract 3249)

"The long-term follow-up of SEQUOIA confirms the sustained efficacy of zanubrutinib over chemotherapy, regardless of IGHV status, in patients with treatment-naïve CLL," said Mazyar Shadman, M.D. M.P.H., Associate Professor and Innovators Network Endowed Chair, Medical Director, Cellular Immunotherapy and the Bezos Family Immunotherapy Clinic at Fred Hutch Cancer Center. He also holds the Innovators Network Endowed Chair at Fred Hutch and is Associate Professor at Fred Hutch and University of Washington. "Notably, there is a deepening of responses, with a complete remission/complete remission with incomplete count recovery rate in the range of 20%, which, based on cross-trial comparison is higher than a typical BTK inhibitor used as monotherapy. Additionally, the incidence of adverse events of interest, such as atrial fibrillation and hypertension, appears comparable to the background risk of this patient population."

In addition to BRUKINSA, BeiGene is advancing a robust pipeline to address the needs of CLL patients, including:

Sonrotoclax (BCL2 Inhibitor): Presented data from the Phase 1/1b study (NCT04277637) demonstrated sonrotoclax, in combination with BRUKINSA, was generally well-tolerated and no cases of tumor lysis syndrome (TLS) were reported in patients with treatment-naïve CLL/SLL. Grade ≥3 treatment-emergent adverse events (TEAEs) occurred in 49.6% of patients, with the most common (≥20%) being neutropenia (24% in 160mg cohort; 23% in 320mg cohort). With a median follow-up of 19.4 months (0.4–33.3 months), the combination achieved a 99% overall response rate (ORR), including in patients with high-risk features (51% had unmutated IGHV, 20% had TP53 mutation, and 9% had del(17p)). High and early rates of undetectable minimal residual disease (uMRD) were seen by week 24 of combination therapy, with responses continuing to deepen with time through week 48. Best uMRD rate was achieved in 92% of patients (n=112). At a median follow-up of over a year and a half, no progression has been observed in the 320 mg dose cohort. These data support continued evaluation of this combination in the ongoing registrational Phase 3 fixed-duration CELESTIAL-TNCLL study (NCT06073821) (Abstract 1012)
BGB-16673 (BTK CDAC): Data from the Phase 1/2 CaDAnCe-101 CLL study (NCT05006716) demonstrated that treatment with BGB-16673 was generally well tolerated in this heavily pretreated population of patients. Promising antitumor activity was observed in patients with high-risk features, including in patients with BTK inhibitor-resistant mutations and those previously exposed to covalent BTK inhibitors, noncovalent BTK inhibitors, and BCL2 inhibitors. No atrial fibrillation was observed in either the CLL/SLL or WM cohorts.
From the cohort of CLL/SLL patients, BGB-16673 demonstrated an ORR of 94% at the 200mg dose. Furthermore, amongst all doses delivered, 2 patients achieved a complete remission/complete remission with incomplete count recovery (CR/CRi). Grade ≥3 TEAEs were reported in 57% of patients. The most common grade ≥3 TEAEs (≥10%) were neutropenia/neutrophil count decreased (20%) and pneumonia (10%). (Abstract 885)
From the cohort of Waldenström’s macroglobulinemia patients, BGB-16673 demonstrated a 93% disease control rate (DCR) and 26% very good partial response (VGPR). Grade ≥3 TEAEs were reported in 45% of patients. The most common grade ≥3 TEAE (≥20%) was neutropenia/neutrophil count decreased. (Abstract 860)

About Chronic Lymphocytic Leukemia

Chronic lymphocytic leukemia (CLL) is a life-threatening cancer of adults. It is a type of mature B-cell malignancy in which abnormal leukemic B lymphocytes (a type of white blood cells) arise from the bone marrow and flood peripheral blood, bone marrow, and lymphoid tissues.1,2 CLL is the most common type of leukemia in adults, accounting for about one-third of new cases.2,3 Approximately 20,700 new cases of CLL will be diagnosed in the U.S. in 2024.3

About Sonrotoclax (BGB-11417)

Sonrotoclax is designed to block the B-cell lymphoma 2 (BCL2) protein, which helps cancer cells survive. It is part of a group of drugs called BH3 mimetics, which mimic natural cell death signals. Studies in the lab and during early drug development have shown that sonrotoclax is a potent and specific inhibitor of BCL2 with a short half-life and no accumulation. Sonrotoclax has shown promising clinical activity across a range of B-cell malignancies, and more than 1,300 patients have been enrolled to date across the global development program. The U.S. Food and Drug Administration (FDA) granted sonrotoclax Fast Track Designation for the treatment of patients with mantle cell lymphoma (MCL) and Waldenström macroglobulinemia (WM).

About BGB‑16673

BGB‑16673 is an orally available, brain-penetrating Bruton’s tyrosine kinase (BTK) targeting chimeric degradation activation compound (CDAC) designed to promote the degradation, or breakdown, of both wildtype and mutant forms of BTK, including those that commonly result in resistance to BTK inhibitors in patients who experience progressive disease. BGB-16673 is the most advanced BTK degrader in the clinic, with more than 350 patients treated to date across the global clinical development program. The U.S. Food and Drug Administration (FDA) granted Fast Track Designation to BGB-16673 for the treatment of adult patients with relapsed or refractory (R/R) chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) who have been previously treated with at least two prior lines of therapy, including BTK inhibitor (BTKi) and B-cell lymphoma 2 (BCL2) inhibitor, and adult patients with R/R mantle cell lymphoma (MCL).

About BRUKINSA (zanubrutinib)

BRUKINSA is an orally available, small molecule inhibitor of Bruton’s tyrosine kinase (BTK) designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.

BRUKINSA has the broadest label globally of any BTK inhibitor and is the only BTK inhibitor to provide the flexibility of once or twice daily dosing. The global BRUKINSA clinical development program includes about 6,000 patients enrolled in 30 countries and regions across more than 35 trials. BRUKINSA is approved in more than 70 markets, and more than 100,000 patients have been treated globally.

U.S. Indications and Important Safety Information for BRUKINSA (zanubrutinib)

INDICATIONS

BRUKINSA is a kinase inhibitor indicated for the treatment of adult patients with:

Chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
Waldenström’s macroglobulinemia (WM).
Mantle cell lymphoma (MCL) who have received at least one prior therapy.
Relapsed or refractory marginal zone lymphoma (MZL) who have received at least one anti-CD20-based regimen.
Relapsed or refractory follicular lymphoma (FL), in combination with obinutuzumab, after two or more lines of systemic therapy.
The MCL, MZL and FL indications are approved under accelerated approval based on overall response rate and durability of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials.

IMPORTANT SAFETY INFORMATION

Warnings and Precautions

Hemorrhage

Fatal and serious hemorrhage has occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher hemorrhage including intracranial and gastrointestinal hemorrhage, hematuria, and hemothorax was reported in 3.8% of patients treated with BRUKINSA in clinical trials, with fatalities occurring in 0.2% of patients. Bleeding of any grade, excluding purpura and petechiae, occurred in 32% of patients.

Bleeding has occurred in patients with and without concomitant antiplatelet or anticoagulation therapy. Coadministration of BRUKINSA with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage.

Monitor for signs and symptoms of bleeding. Discontinue BRUKINSA if intracranial hemorrhage of any grade occurs. Consider the benefit-risk of withholding BRUKINSA for 3-7 days before and after surgery depending upon the type of surgery and the risk of bleeding.

Infections

Fatal and serious infections (including bacterial, viral, or fungal infections) and opportunistic infections have occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher infections occurred in 26% of patients, most commonly pneumonia (7.9%), with fatal infections occurring in 3.2% of patients. Infections due to hepatitis B virus (HBV) reactivation have occurred.

Consider prophylaxis for herpes simplex virus, pneumocystis jirovecii pneumonia, and other infections according to standard of care in patients who are at increased risk for infections. Monitor and evaluate patients for fever or other signs and symptoms of infection and treat appropriately.

Cytopenias

Grade 3 or 4 cytopenias, including neutropenia (21%), thrombocytopenia (8%) and anemia (8%) based on laboratory measurements, developed in patients treated with BRUKINSA. Grade 4 neutropenia occurred in 10% of patients, and Grade 4 thrombocytopenia occurred in 2.5% of patients.

Monitor complete blood counts regularly during treatment and interrupt treatment, reduce the dose, or discontinue treatment as warranted. Treat using growth factor or transfusions, as needed.

Second Primary Malignancies

Second primary malignancies, including non-skin carcinoma, have occurred in 14% of patients treated with BRUKINSA. The most frequent second primary malignancy was non-melanoma skin cancers (8%), followed by other solid tumors in 7% of the patients (including melanoma in 1% of patients) and hematologic malignancies (0.7%). Advise patients to use sun protection and monitor patients for the development of second primary malignancies.

Cardiac Arrhythmias

Serious cardiac arrhythmias have occurred in patients treated with BRUKINSA. Atrial fibrillation and atrial flutter were reported in 4.4% patients treated with BRUKINSA, including Grade 3 or higher cases in 1.9% of patients. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk. Grade 3 or higher ventricular arrhythmias were reported in 0.3% of patients.

Monitor for signs and symptoms of cardiac arrhythmias (e.g., palpitations, dizziness, syncope, dyspnea, chest discomfort), manage appropriately, and consider the risks and benefits of continued BRUKINSA treatment.

Hepatotoxicity, Including Drug-Induced Liver Injury

Hepatotoxicity, including severe, life-threatening, and potentially fatal cases of drug-induced liver injury (DILI), has occurred in patients treated with Bruton tyrosine kinase inhibitors, including BRUKINSA.

Evaluate bilirubin and transaminases at baseline and throughout treatment with BRUKINSA. For patients who develop abnormal liver tests after BRUKINSA, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold BRUKINSA. Upon confirmation of DILI, discontinue BRUKINSA.

Embryo-Fetal Toxicity

Based on findings in animals, BRUKINSA can cause fetal harm when administered to a pregnant woman. Administration of zanubrutinib to pregnant rats during the period of organogenesis caused embryo-fetal toxicity, including malformations at exposures that were 5 times higher than those reported in patients at the recommended dose of 160 mg twice daily. Advise women to avoid becoming pregnant while taking BRUKINSA and for 1 week after the last dose. Advise men to avoid fathering a child during treatment and for 1 week after the last dose. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.

Adverse Reactions

The most common adverse reactions (≥30%), including laboratory abnormalities, in patients who received BRUKINSA (N=1729) are decreased neutrophil count (51%), decreased platelet count (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%).

Drug Interactions

CYP3A Inhibitors: When BRUKINSA is co-administered with a strong CYP3A inhibitor, reduce BRUKINSA dose to 80 mg once daily. For coadministration with a moderate CYP3A inhibitor, reduce BRUKINSA dose to 80 mg twice daily.

Lantern Pharma Announces First Patient Enrolled in Taiwan for Phase 2 HARMONIC™ Clinical Trial of LP-300 in Never-Smoker NSCLC Patients

On December 9, 2024 Lantern Pharma Inc. (NASDAQ: LTRN), an artificial intelligence (AI) company developing targeted cancer therapies using its proprietary RADR AI platform, reported that the first patient has been enrolled and dosed in Taiwan for its Phase 2 HARMONIC clinical trial evaluating LP-300 in never-smoker patients with non-small cell lung cancer (NSCLC) who have progressed after receiving treatment with tyrosine kinase inhibitors (TKIs) (Press release, Lantern Pharma, DEC 9, 2024, View Source [SID1234648930]).

The enrollment of the first patient in Taiwan extends the recent expansion of the HARMONIC trial into Asia, where there is a notably higher prevalence of never-smoker NSCLC patients compared to Western populations. Taiwan represents a particularly important region for the trial, as more than half of all new lung cancer diagnoses in Taiwan occur in people who are classified as never-smokers. Never-smokers in the context of lung cancer have been commonly defined, by the CDC and other health agencies, as people who have smoked less than 100 cigarettes in their lifetime.

"The enrollment of our first patient in Taiwan marks another important milestone in the expansion of our HARMONIC trial," said Panna Sharma, President and CEO of Lantern Pharma. "The extremely high proportion of never-smoker lung cancer patients in Taiwan makes this region important for accelerating our enrollment with the objective of addressing a critical unmet need in a population where this disease has an outsized impact."

The scientific and clinical community is increasingly recognizing that lung cancers in nonsmokers and never-smokers represent a distinct disease entity with unique clinical, genomic, pathological, and biological characteristics. Lantern believes that this has particular importance for the Harmonic trial, as it underscores the need of targeted, precision therapy approaches for this unique patient population. Lung cancer in never-smokers constitutes one of the top 10 causes of cancer-related deaths globally, making it a crucial focus for therapeutic innovation.

The expansion into Asia follows encouraging preliminary results from the trial’s initial safety lead-in cohort, which demonstrated an 86% clinical benefit rate and 43% objective response rate among the first seven patients. The HARMONIC trial is evaluating LP-300 in combination with carboplatin and pemetrexed in never-smoker NSCLC patients that have relapsed following treatment with TKIs.

Dr. Reggie Ewesuedo, VP of Clinical Development at Lantern Pharma commented, "The initiation of patient dosing in Taiwan demonstrates the continued momentum of our Asia expansion strategy. With active screening now occurring at multiple sites across both Japan and Taiwan, we expect to see accelerated enrollment in the trial. The enthusiasm we’ve seen from clinical collaborators in Taiwan reflects the significant need for new therapeutic options for never-smoker NSCLC patients in this region."

The Phase 2 HARMONIC trial is actively screening in multiple cancer centers in the US, Japan and Taiwan and is expected to enroll up to 90 patients across two treatment arms. The two treatment arms are randomized, at a ratio of 2 to 1, and will compare the co-primary endpoints of PFS (progression free survival) and OS (median overall survival) of:

– the LP-300 arm which is expected to enroll 60 patients (LP-300 which will be given in combination with the standard of care chemotherapy doublet)
– the SOC arm which is expected to enroll 30 patients (the standard of care arm will only dose patients with the chemotherapy doublet alone).

Initial results from the Phase 2 clinical trial from the lead-in patient cohort can be reviewed in an earlier press release issued by Lantern Pharma. Lantern plans to review, and share the interim data from, the Phase 2 trial for PFS and OS (co-primary endpoints) after 30 clinical events have been observed.

About LP-300

LP-300 is a disulfide small molecule and an investigational new drug candidate. It has been well characterized to have a multimodal mechanism of action directed towards tyrosine kinase receptors and cell redox enzymes. It is believed to modulate cellular redox in key signaling pathways in NSCLC and directly engage with TKI receptors via cysteine modification.

It is known that lung carcinomas in never smoker patients have a much higher percentage of mutations in certain tyrosine kinase (TK) oncogenes such as EGFR, ALK, ROS, and MET-1, contributing to tumor formation and growth, while lung carcinomas in smokers are much more likely to have growth-driver mutations in oncogenes such as RAS, and much lower percentages of mutations in TK oncogenes. Both published (Parker 2015) and unpublished studies have shown that LP-300 covalently binds to and/or inhibits the kinase activity of each of these TK oncogenes (EGFR, ALK, ROS, and MET-1), suggesting that a greater number of lung adenocarcinomas in never smokers, compared to smokers, could be susceptible to the inhibitory effects of LP-300.

LP-300 has been evaluated in 5 Phase 1 and 5 Phase 2 or 3 clinical trials in over 1,000 subjects. In a retrospective subgroup analysis from a prior Phase 3 trial, never smoker lung adenocarcinoma patients receiving the combination of LP-300 with cisplatin and paclitaxel chemotherapy were observed to have significant survival benefit compared to the never smoker patients receiving cisplatin and paclitaxel without LP-300.
