Expanding access to stem cell transplants: Not a perfect match, yet perhaps just as good
Presentation Time and Location: Friday, May 31, 3:45 p.m. CT, S100bc

Access to potentially lifesaving stem cell transplants traditionally has been limited due to the need for a donor whose stem cells match the recipient’s genes. However, Monzr M. Al Malki, M.D., City of Hope hematologist-oncologist, co-led a multicenter phase 2 trial (NCT04904588) sponsored by NMDP and conducted via CIBMTR (Center for International Blood and Marrow Transplant Research) that demonstrates encouraging overall survival one year after older patients with advanced blood cancers received "HLA-mismatched unrelated donor peripheral blood stem cell transplantation," meaning the donor stem cells originated from someone who was not a relative and not a complete HLA match.

While the 13-site ongoing trial includes adults and children, this interim analysis that will be presented as an oral abstract presentation evaluated the first 70 older adult patients with advanced blood cancers who received this type of transplant and underwent both reduced intensity conditioning and post-transplant cyclophosphamide, which is a method used to prevent a potentially life-threatening side effect called graft-versus-host disease (GVHD). City of Hope has performed over 19,000 transplants, is one of the nation’s leading transplant programs and is at the forefront of using transplants to treat older adults with blood cancers.

Overall survival at one year post-stem cell transplant was 79%. Rates of GVHD and other complications were comparable to those of recipients who received HLA-matched donor stem cells, suggesting HLA-mismatched unrelated donor peripheral blood stem cell transplantation may one day be used more widely, expanding access to the lifesaving therapy.

"This data, supported by the National Marrow Donor Program, is promising and is the reason why I continue to work to expand access to stem cell transplantation for older patients, underrepresented people and patients with blood cancers," Dr. Al Malki said.

The adult cohorts of this trial recruitment have closed with more than 200 patients in follow-up. The pediatric arm of the trial is ongoing.

Bispecific antibody demonstrates sustained response rates in lymphoma patients who received and rejected previous treatments
Presentation Time and Location: Saturday, June 1, 5:24 p.m. CT, S100bc

In an updated efficacy and safety phase 1/2 trial (NCT03075696), bispecific antibody glofitamab continues to demonstrate compelling response rates with a fixed-duration treatment among a group of mantle cell lymphoma patients who have nearly exhausted approved treatment options due to aggressive disease.

The researchers evaluated close to 60 participants who had received two or more previous treatments — the majority of which had stopped responding to treatment before they enrolled in this study. Patients received about 7.4 months of glofitamab. Landmark analyses indicated that most patients with a complete response at the end of treatment were alive without disease progression 15 months after the end of treatment. The median duration of complete response was 12.6 months, and median progression-free survival was 8.6 months.

"People with mantle cell lymphoma have a rare form of non-Hodgkin lymphoma that is currently incurable, so it is encouraging to see people who were told by others that there is not much more to be done live months and even years longer with this treatment," said Tycel Phillips, M.D., City of Hope hematologist-oncologist and presenting author. "We at City of Hope continuously develop leading-edge treatments for people diagnosed with lymphoma and other blood cancers."

Early safety and clinical efficacy data on monotherapy DFF332 in advanced kidney cancer patients
Presentation Time and Location: Saturday, June 1, from 8:30 a.m. CT, S100bc

People with an advanced kidney cancer called clear cell renal cell carcinoma (ccRCC) appeared to experience positive medicinal effects from the targeted therapy pill DFF332 while encountering manageable side effects in an ongoing first-in-human phase 1/1B multicenter trial (CDFF332A12101, NCT04895748).

Sumanta "Monty" Pal, M.D., a City of Hope medical oncologist, will share preliminary data on 40 advanced kidney cancer patients who took DFF332, an oral hypoxia-inducible factor (HIF)-2α inhibitor that has been shown in preclinical models to be effective in reducing ccRCC tumors. All study participants had received at least one other type of therapy before joining the clinical trial. At data cutoff, 16 patients continued to be treated, while 19 patients (48%) stopped receiving the treatment due to disease progression. The most common side effects were fatigue (33%), anemia (30%), increased blood cholesterol and constipation (15%). No extreme adverse effects have been observed so far. At cutoff, 18 patients (45%) had stable disease and two patients (5%) achieved partial response.

"While the study is still in process, so far, we have seen a promising safety profile for monotherapy DFF332 with indications of clinical activity," Dr. Pal said. "We are conducting analysis on how the medicine moves within the body as well as collecting biomarker data that will be shared at our ASCO (Free ASCO Whitepaper) presentation."

Using telehealth to improve access to supportive care services for older adults with cancer living in lower-resourced communities
Presentation Time and Location: Saturday, June 1, at 1:39 p.m. CT, S102

A study at City of Hope | Antelope Valley found that telehealth can be leveraged to offer older adults living in high-poverty, lower resourced communities with a specialized evaluation developed at City of Hope called a geriatric assessment, which identifies supportive care services older adults with cancer need to manage vulnerabilities, better define care goals and improve quality of life.

This quality improvement study included 251 participants who were 65 years or older with newly diagnosed or advanced cancer. These patients underwent a baseline geriatric assessment and most had initial visits with a geriatric nurse practitioner – 197 via televideo and 45 via telephone. The assessment identified vulnerabilities in 209 patients and, after review, the nurse practitioner made 460 necessary referrals for supportive care services – 86% of which were implemented. The most common referrals were to pharmacy (177), social work (142), occupational therapy (76) and physical therapy (48). More than 92% of patients reported they were satisfied with the telehealth services that resulted in supportive care interventions for older adults.

"In my experience, if you don’t do a geriatric assessment, the patient pays for it later," said Tanyanika Phillips, M.D., M.P.H., presenting author and City of Hope medical oncologist and hematologist in Antelope Valley, California. Phillips noted that if care is prescribed without accurate health information, the result could be serious side effects or even hospitalization, which could lead not only to more costly care but also cancer treatment outcomes that are not the best for patients.

"In a general visit, patients often will say they feel well and are fine because they’re incentivized to answer in the affirmative and move forward with treatment," Phillips added. "Place this same patient in a different environment where they are answering geriatric assessment questions, and they may be more forthcoming and detailed about their lifestyle and abilities. This candor will help physicians prescribe the most appropriate care for that individual based on their circumstances."

Providing supportive care interventions via telehealth based on a geriatric assessment is shown to improve daily functioning, happiness and quality of life
Presentation Time and Location: Sunday, June 2, from 11:54 a.m. CT, S100bc

A randomized trial at a Brazilian cancer center and under the guidance of City of Hope’s internationally renowned cancer and aging expert William Dale, M.D., Ph.D., found that older adults with metastatic cancer reported experiencing significant improvements in the performance of daily activities, emotional well-being and quality of life after receiving a telehealth-based geriatric assessment (GA) that resulted in supportive care interventions. This data extends City of Hope’s prior work in GA-guided supportive care beyond the borders of the United States.

"Our studies continue to prove that patients and families win when care teams ask older adults with cancer the right questions at the outset to guide care. This is true even when telehealth is used in a low-resource environment. Guidance from a GA can change care choices and improve outcomes — all without making cancer therapy less effective. It’s a form of precision medicine: more appropriate supportive care interventions, better daily functioning, higher quality of life and the same great cancer care results. It’s a winning formula for patients, families, providers and the health system," said Dr. Dale, senior author of the study, City of Hope’s George Tsai Family Chair in Geriatric Oncology and director of City of Hope’s Center for Cancer and Aging. Dr. Dale is the recipient of this year’s B.J. Kennedy Geriatric Oncology Award, which honors geriatric oncologists who have demonstrated outstanding leadership and achievement in the field of geriatric oncology.

While Tyrosine Kinase Inhibitors (TKI), including dasatinib, have profoundly improved clinical outcomes in patients with chronic myeloid leukemia (CML), the bioavailability and systematic exposure of the crystalline formulation of dasatinib is reduced by comedication with acid reducing agents which may affect the clinical response and comedication with proton pump inhibitors, such as omeprazole, should be avoided (2).

The collaborative analysis with Uppsala University and the Karolinska Institute and University Hospital demonstrates that 54% of CML patients identified in the Swedish CML-register were prescribed at least one PPI and 34% of TKI-treated patients were comedicated with a PPI. Of those prescribed a PPI, 66% of the prescriptions were by a different healthcare provider. Further, the presentation provides new information on the bioavailability of crystalline dasatinib when comedicated with a PPI, demonstrating a substantially higher than previously reported impact of PPIs on the bioavailability of crystalline dasatinib, with Cmax and AUC24 being reduced by 96% and 88% respectively.

"Consistent absorption and bioavailability of dasatinib are critical for adequate disease control and patient outcomes, this is however often overlooked in clinical practice as our data demonstrates," said Per Andersson, CEO of Xspray. "To address this important issue, we are on track to launch Dasynoc, our optimized version of dasatinib, with a Prescription Act Use Fee Amendment date (PDUFA-date) of 31st of July 2024 and the US commercial launch of Dasynoc on 1st September 2024."

CARVYKTI 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. Please see Section 5.4; Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (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 (ICANS) 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%) [see Adverse Reactions (6.1)].

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 [see Dosage and Administration (2.3)].

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.

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), 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.

ABOUT CARVYKTI (CILTACABTAGENE AUTOLEUCEL; CILTA-CEL)

Ciltacabtagene autoleucel is a BCMA-directed, genetically modified autologous T-cell immunotherapy, which involves reprogramming a patient’s own T-cells with a transgene encoding a chimeric antigen receptor (CAR) that identifies and eliminates cells that express BCMA. The cilta-cel CAR protein features two BCMA-targeting single domain antibodies 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.1

In December 2017, Legend Biotech entered into an exclusive worldwide license and collaboration agreement with Janssen Biotech, Inc. (Janssen), a Johnson & Johnson company, to develop and commercialize cilta-cel. In February 2022, cilta-cel was approved by the U.S. Food and Drug Administration (FDA) under the brand name CARVYKTI for the treatment of adults with relapsed or refractory multiple myeloma. In April 2024, cilta-cel was approved for the second-line treatment of patients with relapsed/refractory myeloma who have received at least one prior line of therapy including a proteasome inhibitor, an immunomodulatory agent, and are refractory to lenalidomide.

In May 2022, the European Commission (EC) granted conditional marketing authorization of CARVYKTI for the treatment of adults with relapsed and refractory multiple myeloma. In September 2022, Japan’s Ministry of Health, Labour and Welfare (MHLW) approved CARVYKTI. Cilta-cel was granted Breakthrough Therapy Designation in the U.S. in December 2019 and in China in August 2020. In addition, cilta-cel received a PRIority MEdicines (PRIME) designation from the European Commission in April 2019. Cilta-cel also received Orphan Drug Designation from the U.S. FDA in February 2019, from the European Commission in February 2020, and from the Pharmaceuticals and Medicinal Devices Agency (PMDA) in Japan in June 2020. In March 2022, the European Medicines Agency’s Committee for Orphan Medicinal Products recommended by consensus that the orphan designation for cilta-cel be maintained on the basis of clinical data demonstrating improved and sustained complete response rates following treatment.

ABOUT CARTITUDE-2

CARTITUDE-2 (NCT04133636) is an ongoing Phase 2 multicohort study evaluating the safety and efficacy of cilta-cel in various clinical settings (Cohorts A, B, C, D, E, F, G, H).2

ABOUT CARTITUDE-4

CARTITUDE-4 (NCT04181827) is an ongoing, international, randomized, open-label Phase 3 study evaluating the efficacy and safety of cilta-cel versus pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd) in adult patients with relapsed and lenalidomide-refractory multiple myeloma who received one to three prior lines of therapy, including a PI and an IMiD.3

ABOUT MULTIPLE MYELOMA

Multiple myeloma is an incurable blood cancer that starts in the bone marrow and is characterized by an excessive proliferation of plasma cells.4 In 2024, it is estimated that more than 35,000 people will be diagnosed with multiple myeloma, and more than 12,000 people will die from the disease in the U.S.5 While some patients with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems or infections.

About OBX-115
Obsidian’s lead investigational cytoTIL15 program, OBX-115, is a novel engineered tumor-derived autologous T cell immunotherapy (tumor-infiltrating lymphocyte [TIL] cell therapy) armored with pharmacologically regulatable membrane-bound IL15 (mbIL15). OBX-115 has the potential to become a meaningful therapeutic option for patients with advanced or metastatic melanoma and other solid tumors by leveraging the expected benefits of mbIL15 and Obsidian’s proprietary, differentiated manufacturing process to enhance persistence, antitumor activity, and clinical safety of TIL cell therapy. OBX-115 is being investigated in two ongoing clinical trials in advanced or metastatic melanoma and non-small cell lung cancer (NSCLC) (NCT05470283 and NCT06060613).
