On December 09, 2024 Kite, a Gilead Company (Nasdaq: GILD), reported results from a five-year follow-up analysis of ZUMA-5, a Phase 2 study of Yescarta (axicabtagene ciloleucel) in patients with relapsed/refractory non-Hodgkin lymphomas (NHL) including follicular lymphoma (FL) or marginal zone lymphoma (MZL) (Press release, Gilead Sciences, DEC 9, 2024, View Source [SID1234648952]). The analysis demonstrated that after a median follow-up of more than five years, patients treated with Yescarta continued to experience durable response and long-term survival. The data were shared in an oral presentation (Abstract #864) during the 66th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition.

"Relapsed or refractory non-Hodgkin lymphomas, including follicular lymphoma and marginal zone lymphoma, are generally considered to be incurable, with most patients ultimately relapsing," said Dr. Sattva S. Neelapu, lead investigator, The University of Texas MD Anderson Cancer Center. "These impressive results demonstrate the continued durable clinical benefit and manageable long-term safety profile of axi-cel and give us hope that it may have a curative effect on these difficult-to-treat blood cancers."

In ZUMA-5, 159 patients were enrolled (127 FL, 31 MZL, 1 DLBCL [later excluded]). At a median follow-up of 64.6 months (range, 32.3-81.4; FL: 65.7, MZL: 55.8), the overall response rate (ORR) was 90% and the complete response (CR) was 75%. Among patients who achieved a CR, 58% remained in CR at the time of data cutoff. The median duration of response (DOR) was 60.4 months (95% CI, 39.7-not estimable [NE]; FL: 60.4, MZL: not reached [NR]), with estimated 60-month DOR of 53.4% (95% CI, 43.9-62.0; FL: 52.2%, MZL: 60.0%).

Median progression-free survival (PFS) was 62.2 months (95% CI, 34.9-NE; FL: 57.3, MZL: NR). PFS rates at 60 months in patients with FL were consistent regardless of high-risk characteristics.

Median time to next therapy was NR in all patients with NHL (95% CI, 38.6-NE; consistent by disease type), with a 60-month estimated rate of 53.3% (95% CI, 45.0-60.9; FL: 54.0%, MZL: 50.9%). At data cutoff, 55% of patients (n=87) were alive with no new anticancer therapy. The median overall survival (OS) was NR (95% CI, NE-NE; consistent by disease type), and the 60-month OS estimate was 69.0% (95% CI, 60.8-75.8; FL: 68.9, MZL: 71.1).

"There is growing evidence that people with follicular lymphoma and marginal zone lymphoma can experience long-term survival after one Yescarta treatment," said Dominique Tonelli, VP, Global Head of Medical Affairs, Kite. "With no lymphoma-specific events in the five-year follow-up of ZUMA-5 patients, Yescarta may offer patients the chance to live longer without need for subsequent therapy and a potential cure."

No new Yescarta-related safety signals emerged in the five-year analysis. One patient progressed after the data cutoff of the four-year analysis and no patients died of disease progression after the prior analysis. Among treated patients (n=152, 124 FL, 28 MZL), three new events not related to Yescarta were reported after the four-year analysis, including Grade 3 metastasis, Grade 1 bladder cancer, and Grade 4 myelodysplastic syndrome (a serious adverse event). One patient died of pneumonia, unrelated to Yescarta. At any time on trial, a total of 46 patients died, due to progressive disease (n=14), secondary malignancies (n=6), infections (n=11), or another or unknown cause (n=15).

About ZUMA-5

ZUMA-5 is a single-arm, open-label, international, multicenter Phase 2 study evaluating 159 adult patients with R/R NHL (FL and MZL) who received at least two prior lines of systemic therapy, including the combination of an anti-CD20 monoclonal antibody and an alkylating agent. The primary endpoint was ORR, and secondary endpoints included CR rate, ORR and CR in patients who had received three or more lines of prior therapy, DOR, OS, PFS and incidence of adverse events.

About NHL

FL and MZL are both forms of indolent NHL in which malignant tumors slowly grow but can become more aggressive over time.

FL is the most common form of indolent lymphoma and the second most common type of lymphoma globally. It accounts for approximately 22 percent of all lymphomas diagnosed worldwide. MZL is the third most common lymphoma, accounting for 8 to 12 percent of all B-cell NHLs.

Despite advances in management and substantial improvements in long-term survival, patients living with FL have varied outcomes. Currently, there are limited options for the treatment of relapsed or refractory FL and MZL after two or more lines of therapy.

U.S. IMPORTANT SAFETY INFORMATION

BOXED WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES and SECONDARY HEMATOLOGICAL MALIGNANCIES

Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving YESCARTA. Do not administer YESCARTA to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.
Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving YESCARTA, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with YESCARTA. Provide supportive care and/or corticosteroids, as needed.
T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including YESCARTA.
YESCARTA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the YESCARTA and TECARTUS REMS Program.
CYTOKINE RELEASE SYNDROME (CRS)

CRS, including fatal or life-threatening reactions, occurred following treatment with YESCARTA. CRS occurred in 90% (379/422) of patients with non-Hodgkin lymphoma (NHL) receiving YESCARTA, including ≥ Grade 3 (Lee grading system1) CRS in 9%. CRS occurred in 93% (256/276) of patients with large B-cell lymphoma (LBCL), including ≥ Grade 3 CRS in 9%. Among patients with LBCL who died after receiving YESCARTA, four had ongoing CRS events at the time of death. For patients with LBCL in ZUMA-1, the median time to onset of CRS was 2 days following infusion (range: 1 to 12 days) and the median duration of CRS was 7 days (range: 2 to 58 days). For patients with LBCL in ZUMA-7, the median time to onset of CRS was 3 days following infusion (range: 1 to 10 days) and the median duration was 7 days (range: 2 to 43 days).

CRS occurred in 84% (123/146) of patients with indolent non-Hodgkin lymphoma (iNHL) in ZUMA-5, including ≥ Grade 3 CRS in 8%. Among patients with iNHL who died after receiving YESCARTA, one patient had an ongoing CRS event at the time of death. The median time to onset of CRS was 4 days (range: 1 to 20 days) and the median duration was 6 days (range: 1 to 27 days) for patients with iNHL.

Key manifestations of CRS (≥ 10%) in all patients combined included fever (85%), hypotension (40%), tachycardia (32%), chills (22%), hypoxia (20%), headache (15%), and fatigue (12%). Serious events that may be associated with CRS include, cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), renal insufficiency, cardiac failure, respiratory failure, cardiac arrest, capillary leak syndrome, multi-organ failure, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS).

The impact of tocilizumab and/or corticosteroids on the incidence and severity of CRS was assessed in two subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received tocilizumab and/or corticosteroids for ongoing Grade 1 events. CRS occurred in 93% (38/41), including 2% (1/41) with Grade 3 CRS; no patients experienced a Grade 4 or 5 event. The median time to onset of CRS was 2 days (range: 1 to 8 days) and the median duration of CRS was 7 days (range: 2 to 16 days).

Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Thirty-one of the 39 patients (79%) developed CRS at which point the patients were managed with tocilizumab and/or therapeutic doses of corticosteroids with no patients developing Grade 3 or higher CRS. The median time to onset of CRS was 5 days (range: 1 to 15 days) and the median duration of CRS was 4 days (range: 1 to 10 days). Although there is no known mechanistic explanation, consider the risk and benefits of prophylactic corticosteroids in the context of pre-existing comorbidities for the individual patient and the potential for the risk of Grade 4 and prolonged neurologic toxicities.

Ensure that 2 doses of tocilizumab are available prior to infusion of YESCARTA. Monitor patients at least daily for 7 days at the certified healthcare facility following infusion for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for 4 weeks after infusion. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated.

NEUROLOGIC TOXICITIES

Neurologic toxicities (including immune effector cell-associated neurotoxicity syndrome) that were fatal or life- threatening occurred. Neurologic toxicities occurred in 78% (330/422) of all patients with NHL receiving YESCARTA, including ≥ Grade 3 in 25%. Neurologic toxicities occurred in 87% (94/108) of patients with LBCL in ZUMA-1, including ≥ Grade 3 in 31% and in 74% (124/168) of patients in ZUMA-7 including ≥ Grade 3 in 25%. The median time to onset was 4 days (range: 1-43 days) and the median duration was 17 days for patients with LBCL in ZUMA-1. The median time to onset for neurologic toxicity was 5 days (range:1- 133 days) and median duration was 15 days in patients with LBCL in ZUMA-7. Neurologic toxicities occurred in 77% (112/146) of patients with iNHL, including ≥ Grade 3 in 21%. The median time to onset was 6 days (range: 1-79 days) and the median duration was 16 days. Ninety-eight percent of all neurologic toxicities in patients with LBCL and 99% of all neurologic toxicities in patients with iNHL occurred within the first 8 weeks of YESCARTA infusion. Neurologic toxicities occurred within the first 7 days of infusion for 87% of affected patients with LBCL and 74% of affected patients with iNHL.

The most common neurologic toxicities (≥ 10%) in all patients combined included encephalopathy (50%), headache (43%), tremor (29%), dizziness (21%), aphasia (17%), delirium (15%), and insomnia (10%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events, including aphasia, leukoencephalopathy, dysarthria, lethargy, and seizures occurred. Fatal and serious cases of cerebral edema and encephalopathy, including late-onset encephalopathy, have occurred.

The impact of tocilizumab and/or corticosteroids on the incidence and severity of neurologic toxicities was assessed in 2 subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received corticosteroids at the onset of Grade 1 toxicities, neurologic toxicities occurred in 78% (32/41) and 20% (8/41) had Grade 3 neurologic toxicities; no patients experienced a Grade 4 or 5 event. The median time to onset of neurologic toxicities was 6 days (range: 1-93 days) with a median duration of 8 days (range: 1-144 days). Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Of those patients, 85% (33/39) developed neurologic toxicities, 8% (3/39) developed Grade 3, and 5% (2/39) developed Grade 4 neurologic toxicities. The median time to onset of neurologic toxicities was 6 days (range: 1-274 days) with a median duration of 12 days (range: 1-107 days). Prophylactic corticosteroids for management of CRS and neurologic toxicities may result in higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset and decrease the duration of CRS.

Monitor patients for signs and symptoms of neurologic toxicities at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter, and treat promptly.

REMS

Because of the risk of CRS and neurologic toxicities, YESCARTA is available only through a restricted program called the YESCARTA and TECARTUS REMS Program which requires that: Healthcare facilities that dispense and administer YESCARTA must be enrolled and comply with the REMS requirements and must have on-site, immediate access to a minimum of 2 doses of tocilizumab for each patient for infusion within 2 hours after YESCARTA infusion, if needed for treatment of CRS. Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer YESCARTA are trained about the management of CRS and neurologic toxicities. Further information is available at www.YescartaTecartusREMS.com or 1-844-454-KITE (5483).

HYPERSENSITIVITY REACTIONS

Allergic reactions, including serious hypersensitivity reactions or anaphylaxis, may occur with the infusion of YESCARTA.

SERIOUS INFECTIONS

Severe or life-threatening infections occurred. Infections (all grades) occurred in 45% of patients with NHL. Grade 3 or higher infections occurred in 17% of patients, including ≥ Grade 3 or higher infections with an unspecified pathogen in 12%, bacterial infections in 5%, viral infections in 3%, and fungal infections in 1%. YESCARTA should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after infusion and treat appropriately. Administer prophylactic antimicrobials according to local guidelines.

Febrile neutropenia was observed in 36% of all patients with NHL 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.

In immunosuppressed patients, including those who have received YESCARTA, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive multifocal leukoencephalopathy [PML]) have been reported. The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed. Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells, including YESCARTA. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing.

PROLONGED CYTOPENIAS

Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and YESCARTA infusion. ≥ Grade 3 cytopenias not resolved by Day 30 following YESCARTA infusion occurred in 39% of all patients with NHL and included neutropenia (33%), thrombocytopenia (13%), and anemia (8%). Monitor blood counts after infusion.

HYPOGAMMAGLOBULINEMIA

B-cell aplasia and hypogammaglobulinemia can occur. Hypogammaglobulinemia was reported as an adverse reaction in 14% of all patients with NHL. Monitor immunoglobulin levels after treatment and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement. The safety of immunization with live viral vaccines during or following YESCARTA 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 YESCARTA treatment, and until immune recovery following treatment.

SECONDARY MALIGNANCIES

Patients treated with YESCARTA may develop secondary malignancies. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including YESCARTA. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes.

Monitor life-long for secondary malignancies. In the event that a secondary malignancy occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing.

EFFECTS ON ABILITY TO DRIVE AND USE MACHINES

Due to the potential for neurologic events, including altered mental status or seizures, patients are at risk for altered or decreased consciousness or coordination in the 8 weeks following YESCARTA 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.

ADVERSE REACTIONS

The most common non-laboratory adverse reactions (incidence ≥ 20%) in patients with LBCL in ZUMA-7 included fever, CRS, fatigue, hypotension, encephalopathy, tachycardia, diarrhea, headache, musculoskeletal pain, nausea, febrile neutropenia, chills, cough, infection with unspecified pathogen, dizziness, tremor, decreased appetite, edema, hypoxia, abdominal pain, aphasia, constipation, and vomiting.

The most common adverse reactions (incidence ≥ 20%) in patients with LBCL in ZUMA-1 included CRS, fever, hypotension, encephalopathy, tachycardia, fatigue, headache, decreased appetite, chills, diarrhea, febrile neutropenia, infections with pathogen unspecified, nausea, hypoxia, tremor, cough, vomiting, dizziness, constipation, and cardiac arrhythmias.

The most common non-laboratory adverse reactions (incidence ≥ 20%) in patients with iNHL in ZUMA-5 included fever, CRS, hypotension, encephalopathy, fatigue, headache, infections with pathogen unspecified, tachycardia, febrile neutropenia, musculoskeletal pain, nausea, tremor, chills, diarrhea, constipation, decreased appetite, cough, vomiting, hypoxia, arrhythmia, and dizziness.

On December 09, 2024 Immune-Onc Therapeutics, Inc. ("Immune-Onc"), a private clinical-stage biopharmaceutical company advancing novel therapies in immunology and oncology by targeting myeloid cell inhibitory receptors, reported updated data from its Phase 1b expansion cohort evaluating IO-202, a first-in-class anti-LILRB4 antibody, in combination with azacitidine (AZA) in patients with chronic myelomonocytic leukemia (CMML) (Press release, Immune-Onc Therapeutics, DEC 9, 2024, View Source [SID1234648950]). These new findings were highlighted in an oral presentation at the 2024 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in San Diego, California.

The updated results from this trial in hypomethylating agent-naïve CMML showed that IO-202, in combination with AZA, achieved a complete remission (CR) rate of 50.0% and an overall response rate (ORR) of 66.7% among the 18 efficacy evaluable patients based on the International Working Group (IWG) 2023 response criteria for higher-risk myelodysplastic syndromes.1 Further analysis revealed that efficacy favors patients with high LILRB4 expression, who achieved a CR rate of 83.3% (5/6) and an ORR of 100% (6/6). Responses were observed in patients across all subgroups, including those with proliferative disease, elevated blast counts, unfavorable mutations, and high symptom scores. These findings underscore the potential of IO-202 to address an important unmet need in CMML, where the only approved treatment with hypomethylating agents yields modest CR rates of 7-17%.2

There is a critical need for innovative therapies for CMML, as no new treatments with a novel mechanism of action have been approved in over 30 years. The prognosis for CMML patients remains poor, with a median survival of less than three years. Allogenic hematopoietic cell transplant (HCT) is the only potentially curative option, yet fewer than 15-20% of patients are eligible to undergo HCT. As a novel agent, IO-202 demonstrates promising clinical benefits, addressing a significant unmet need.

In this study, treatment with IO-202 in combination with AZA enabled 38.9% of the patients to successfully bridge to HCT. Additionally, four out of six transfusion-dependent patients became transfusion-independent. IO-202 is well-tolerated at the preliminary recommended Phase 2 dose (60 mg/kg followed by 30 mg/kg every two weeks​) among 21 safety-evaluable patients. No dose-limiting toxicities were reported.

"These results represent a positive advance in the treatment of CMML, a disease with very limited options and poor outcomes," said Gabriel N. Mannis, M.D., IO-202 Phase 1 investigator and associate professor of medicine, division of hematology, Stanford Cancer Institute, Stanford University. "The favorable correlation between LILRB4 expression and treatment response underscores the contribution of IO-202 to efficacy consistent with its mechanism of action. Achieving a 50% complete response rate overall—and an 83% complete response rate in patients with high LILRB4 expression—demonstrates the potential of IO-202 as a highly impactful therapy. Additionally, the ability to bridge nearly 40% of patients to transplant and help most transfusion-dependent patients achieve independence offers new hope for improving outcomes in this challenging disease."

"We are encouraged by the promising clinical activity and tolerability of IO-202 in this trial," said Charlene Liao, Ph.D., chief executive officer of Immune-Onc. "These data support a pivotal study to evaluate IO-202 in combination with azacitidine as a frontline treatment for hypomethylating agent-naïve CMML. We look forward to working closely with regulators to bring this potentially life-changing therapy to patients."

ABOUT CHRONIC MYELOMONOCYTIC LEUKEMIA (CMML)

CMML is a rare form of blood cancer, with an overall incidence of 0.35 cases per 100,000 population in the United States.3 CMML is characterized by persistent elevation of peripheral blood monocytes (≥0.5×109/L; monocytes ≥10% of white blood cell count) for over three months, accompanied by dysplastic features in the bone marrow.4,5 The only FDA-approved therapies currently available for CMML are hypomethylating agents, such as azacitidine, which achieve a complete response rate of just 7-17%.2

ABOUT LILRB4 (also known as ILT3)

LILRB4, also known as ILT3, is an immune-modulatory transmembrane protein found on monocytes and monocyte-derived cells. LILRB4 is expressed on certain hematologic cancer cells, such as myelomonocytic leukemia blasts, and on certain pathogenic cells involved in autoimmunity and inflammatory processes.

ABOUT IO-202

IO-202 is a first-in-class IgG1 antibody with specific, high-affinity binding to LILRB4 and depletes LILRB4 positive cells via antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis. As such, IO-202 is a targeted therapy with broad potential in blood cancers and autoimmune and inflammatory diseases.

IO-202 has completed the dose escalation part of the first-in-human, multicenter, open-label Phase 1 study in the U.S., and the data was presented at the European Hematology Association (EHA) (Free EHA Whitepaper) Congress in 2023. This Phase 1 trial has advanced to the dose expansion stage to evaluate IO-202 in combination with azacitidine (NCT04372433) in patients with newly diagnosed chronic myelomonocytic leukemia (CMML) who have not received any hypomethylating agents (HMA).

The U.S. Food and Drug Administration granted IO-202 Fast Track Designations for the treatment of patients with relapsed or refractory acute myeloid leukemia (AML) and relapsed or refractory CMML, respectively. The FDA has also granted IO-202 Orphan Drug Designations for the treatment of AML and CMML, respectively.

On December 09, 2024 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported that new and updated data from its industry-leading CD20xCD3 T-cell-engaging bispecific antibody program were presented at the 66th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting & Exposition, December 7-10, 2024 (Press release, Genentech, DEC 9, 2024, View Source [SID1234648949]). With more than 20 bispecific antibody abstracts accepted for presentation, data showcase the benefits of fixed-duration Columvi (glofitamab-gxbm) and Lunsumio (mosunetuzumab-axgb) across different types of aggressive and indolent lymphomas. This research supports Genentech’s efforts to continue innovating for patients by advancing treatment standards at earlier stages of disease while exploring additional forms of administration that could further improve the patient experience.

"The data being presented at ASH (Free ASH Whitepaper) offer further evidence that Columvi and Lunsumio can provide lasting remissions for people with advanced lymphoma," said Levi Garraway, M.D., Ph.D., Genentech’s chief medical officer and head of Global Product Development. "The results underscore our ambition to transform the treatment of B-cell malignancies with a range of innovative therapeutic options."

"Lymphoma patients face challenges that extend well beyond the clinical manifestations of their disease, including the physical and emotional strain of frequent appointments and treatments," said Elizabeth Budde, M.D., Ph.D., City of Hope’s executive medical director of its Enterprise Immune Effector Cell Program and associate professor in its Division of Lymphoma, Department of Hematology & Hematopoietic Cell Transplantation. "While Lunsumio’s fixed-duration intravenous formulation has already offered a valuable treatment option, the introduction of a subcutaneous route could provide a shorter administration time. With both routes available, we can better tailor therapy to each patient’s needs, supporting a flexible and patient-centered approach to follicular lymphoma care."

Follow-up data reinforce benefits of fixed-duration therapies beyond the end of treatment

Three-year follow-up from the pivotal Phase II NP30179 study of Columvi in people with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) showed 40.0% of patients achieved a complete response (CR), with a median duration of CR of 29.8 months (95% CI: 22.0–not estimable [NE]). The majority of patients in complete remission at the end of therapy remained in remission two years after therapy completion. Safety appeared consistent with the previous analysis.

Long-term data at four years from the pivotal Phase II GO29781 study of Lunsumio in patients with R/R follicular lymphoma (FL) showed long-lasting remissions, with nearly two-thirds (64.0% [95% CI: 50.1-78.0]) of patients with a CR alive and without disease progression at 45 months. The overall response rate (ORR) and CR rates in the overall population were 77.8% and 60.0%, respectively. Consistent results were seen in patients with a history of disease progression within 24 months of frontline treatment (POD24), which is typically harder to treat. No new safety signals were observed since the previous analysis.

Both studies also showed restoration of B-cell levels, starting from 12-18 months following Columvi treatment and after a median of 19 months following Lunsumio treatment, indicating immune system recovery and supporting the use of a fixed-duration treatment approach. Recovery of B cells following treatment for lymphoma is important so that patients can maintain immune system function.

A U.S. real-world data study and economic model evaluating R/R non-Hodgkin lymphoma patient treatment-related travel burden across different bispecific antibody therapies highlight the impact of travel distance, time and associated costs, an often-overlooked aspect of the patient experience beyond clinical efficacy and safety. These factors play a crucial role in treatment decision-making, further emphasizing the importance of patient-centered treatment options. The study found fixed-duration therapies, such as Columvi and Lunsumio, reduce treatment-related travel burden due to less frequent dosing.

Studies investigating subcutaneously-administered Lunsumio show positive results

Data from a primary analysis of the Phase II GO29781 study of investigational Lunsumio administered subcutaneously in patients with third-line or later FL were presented for the first time. Results show pharmacokinetic non-inferiority compared to intravenous (IV) administration, with fixed-duration Lunsumio achieving high rates of deep and durable remissions, with 76.6% of patients experiencing an ORR and a 61.7% CR rate, as evaluated by the independent review committee. The median progression-free survival was 23.7 months (95% CI: 14.6-NE), while the median overall survival was not reached. The most common all-grade adverse events (AEs) were injection-site reactions (60.6%; all Grade 1-2), fatigue (35.1%), and cytokine release syndrome (CRS; 29.8%). The rate and severity of CRS events were low (Grade 1-2, 27.6%; Grade 3, 2.1%); all occurred during cycle 1 and were resolved. Data has been submitted to health authorities with the aim of offering patients and healthcare providers an alternative treatment and more choice when it comes to administration options depending on their needs.

New data from a randomized Phase II cohort of the investigational GO40516 study showed improved efficacy and manageable safety with outpatient, subcutaneously administered, fixed-duration Lunsumio in combination with Polivy (polatuzumab vedotin-piiq) versus Rituxan (rituximab) in combination with Polivy, in people with R/R LBCL. In the Lunsumio-Polivy arm, the ORR was 77.5% (95% CI: 61.6-89.2) versus 50.0% (95% CI: 33.8–66.2) for Rituxan-Polivy, and the CR rate was 57.5% (95% CI: 40.9-73.0) versus 35.0% (95% CI: 20.6-51.7). AEs of special interest occurring in ≥30% of patients in the Lunsumio-Polivy arm were injection-site reactions (55.0%) and neutropenia (40.0%). CRS events occurred in four (10.0%) patients, all of which were Grade 1-2, occurred during cycle 1 and were resolved. These data support further exploration of this investigational treatment combination in the ongoing Phase III SUNMO study, which could provide an alternative option in second-line DLBCL to meet diverse patient needs.

Additional data support Genentech’s goal to elevate treatment standards in earlier stages of LBCL

Updated data from the Phase I/Ib investigational NP39488 study showed high and durable response rates in people with R/R LBCL treated with Columvi in combination with Polivy, including those with high-grade disease and prior treatment with CAR T-cell therapy. Of the 128 efficacy-evaluable patients, the best ORR was 80.6%, with a CR rate of 62.0%, and the median duration of CR was 31.8 months (95% CI: 21.9-NE). Among patients previously treated with CAR T-cell therapy (n=28), the ORR was 75.0%, with a CR rate of 50.0%. The safety profile was manageable and consistent with the known profiles of the individual drugs. The most common AE was CRS (44.4%), which was mostly Grade 1-2. Results support ongoing development of this investigational combination in the Phase III SKYGLO study investigating Columvi with Polivy-Rituxan, cyclophosphamide, doxorubicin and prednisone (R-CHP) in previously untreated DLBCL.

About Diffuse Large B-Cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is an aggressive (fast-growing) blood cancer and is the most common form of non-Hodgkin’s lymphoma (NHL) in the U.S. While many people with DLBCL are responsive to treatment, the majority of those who relapse or are refractory to subsequent treatments have poor outcomes. DLBCL not otherwise specified is the most common category of large B-cell lymphoma (LBCL) and accounts for about 80% or more of cases. It applies to cases that do not fall into any specific disease subgroups of LBCL.

About Columvi (glofitamab-gxbm)

Columvi is a CD20xCD3 T-cell engaging bispecific antibody designed to target CD3 on the surface of T cells and CD20 on the surface of B cells. Columvi was designed with a novel 2:1 structural format. This T-cell engaging bispecific antibody is engineered to have one region that binds to CD3, a protein on T cells, a type of immune cell, and two regions that bind to CD20, a protein on B cells, which can be healthy or malignant. This dual-targeting brings the T cell in close proximity to the B cell, activating the release of cancer cell-killing proteins from the T cell. Columvi is part of Genentech’s broad and industry-leading CD20xCD3 T-cell-engaging bispecific antibody clinical development program that also includes Lunsumio (mosunetuzumab), which aims to provide tailored treatment options that suit the diverse needs, preferences, and experiences of people with blood cancers and healthcare systems. Genentech is investigating Columvi as a monotherapy and in combination with other medicines for the treatment of diffuse large B-cell lymphoma and mantle cell lymphoma.

Columvi U.S. Indication

Columvi (glofitamab-gxbm) is a prescription medicine to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) or large B-cell lymphoma (LBCL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more prior treatments for their cancer.

It is not known if Columvi is safe and effective in children.

The conditional approval of Columvi is based on response rate and durability of response. There are ongoing studies to establish how well the drug works.

What is the most important information I should know about Columvi?

Columvi can cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with Columvi, and can also be serious and lead to death.

Call your healthcare provider or get emergency medical help right away if you develop any signs or symptoms of CRS, including:

fever of 100.4°F (38°C) or higher
chills or shaking
fast or irregular heartbeat
dizziness or light-headedness
trouble breathing
shortness of breath
Due to the risk of CRS, you will receive Columvi on a "step-up dosing schedule".

A single dose of a medicine called obinutuzumab will be given to you on the first day of your first treatment cycle (Day 1 of Cycle 1).
You will start the Columvi step-up dosing schedule a week after the obinutuzumab dose. The step-up dosing schedule is when you receive smaller "step-up" doses of Columvi on Day 8 and Day 15 of Cycle 1. This is to help reduce your risk of CRS. You should be hospitalized during your infusion and for 24 hours after receiving the first step-up dose on Day 8. You should be hospitalized during your infusion and for 24 hours after receiving the second step-up dose on Day 15 if you experienced CRS during the first step-up dose.
You will receive your first full dose of Columvi a week after the second step-up dose (this will be Day 1 of Cycle 2).
If your dose of Columvi is delayed for any reason, you may need to repeat the "step-up dosing schedule".
If you had more than mild CRS with your previous dose of Columvi, you should be hospitalized during and for 24 hours after receiving your next dose of Columvi.
Before each dose of Columvi, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.
Your healthcare provider will monitor you for CRS during treatment with Columvi and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with Columvi if you have severe side effects.

Carry the Columvi Patient Wallet Card with you at all times and show it to all of your healthcare providers. The Columvi Patient Wallet Card lists the signs and symptoms of CRS you should get emergency medical help for right away.

About Polivy (polatuzumab vedotin-piiq)

Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed specifically in the majority of B cells, an immune cell impacted in some types of non-Hodgkin’s lymphoma (NHL), making it a promising target for the development of new therapies. Polivy binds to cancer cells such as CD79b and destroys these B cells through the delivery of an anti-cancer agent, which is thought to minimize the effects on normal cells. Polivy is being developed by Genentech using Pfizer ADC technology and is currently being investigated for the treatment of several types of NHL.

Polivy U.S. Indication

Polivy is a prescription medicine used with other medicines (a rituximab product, cyclophosphamide, doxorubicin, and prednisone) as a first treatment for adults who have moderate to high risk diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS) or high-grade B-cell lymphoma (HGBL).

Polivy is a prescription medicine used with other medicines, bendamustine and a rituximab product, to treat DLBCL in adults who have progressed after at least 2 prior therapies.

Title: Weekly Selinexor, Bortizomib and Dexamethasone (SVd) Versus Twice Weekly Bortizomib and Dexamethasone (Vd) in Chinese Patients with Relapsed and Refractory Multiple Myeloma (RRMM): Primary Analysis of Phase III Bench Study
Publication Number: 4748
Session: 654. Multiple Myeloma: Pharmacologic Therapies: Poster III
Date: Monday, December 9, 2024
Time: 6:00 PM – 8:00 PM (Pacific time)
10:00 AM – 12:00 PM, December 10, 2024 (Beijing time)

The BENCH study is a Phase III randomized, open-label, multicenter clinical trial, aiming to evaluate the efficacy and safety of selinexor, bortezomib and dexamethasone (SVd) regimen against bortezomib and dexamethasone (Vd) regimen in Chinese adult patients with R/R MM who have received one to three prior lines of therapy. At present, a New Drug Application (NDA) based this study has already been submitted to and accepted by China’s National Medical Products Administration (NMPA).
As of May 9, 2024, a total of 154 Chinese R/R MM patients were randomized to SVd group (n=101) or Vd group (n=53) and 152 patients received at least one dose of study drug (safety population).
Efficacy results showed that the median progression-free survival (mPFS) was 8.1 months with SVd group and 6.3 months with Vd group. The overall response rate (ORR) was higher in SVd group than in Vd group. SVd group had a significantly higher proportion of patients with a very good partial response (VGPR) or better responses. The median time to response and the median duration of response were 0.8 vs 1.4 months and 9.7 vs 7.2 months (SVd vs Vd), respectively.
During the study, some subjects experienced treatment emergent adverse events (TEAEs). The most frequent Grade 3-4 adverse events (AEs) for SVd and Vd (≥10%) included thrombocytopenia, lymphocytopenia, and anemia. The incidence of Grade≥2 peripheral neuropathy (PN) was significantly lower in SVd than in Vd group.
The BENCH study has met its primary and key secondary endpoints, with results consistent with the BOSTON study. These results showed that the SVd regimen decreased the risk of progression and obtained much more profound responses compared to standard Vd regimen in Chinese patients with R/R MM. The incidence of Grade ≥2 PN were significantly reduced.
Title: Selinexor Combined with Tislelizumab in Patients with Relapsed or Refractory Extranodal NK/T-Cell Lymphoma (R/R ENKTL): Preliminary Results of Arm C, from a Multicenter, Single-Arm, Phase I/II Study, Touch
Publication Number: 4448
Session: 625. T Cell, NK Cell, or NK/T Cell Lymphomas: Clinical and Epidemiological: Poster III
Date: Monday, December 9, 2024
Time: 6:00 PM – 8:00 PM (Pacific time)
10:00 AM – 12:00 PM, December 10, 2024 (Beijing time)

The Phase I/II TOUCH study is investigating selinexor combined with different drugs in R/R ENKTL. Arm C of the study aims to evaluate the safety, tolerability and preliminary efficacy of selinexor in combination with anti-PD-1 antibody tislelizumab.
As of 18 May 2024, 17 R/R ENKTL patients were enrolled in Arm C [Sel 40mg (n=3); Sel 60mg (n=14)]. Sixteen patients previously exposed to both L-asparaginase (L-Asp) and checkpoint inhibitors (CPIs) including 8 patients who had received prior Tislelizumab (Tis); eleven (64.7%) patients were refractory to their last-line therapy.
Efficacy results showed that, of 16 CPIs exposed patients (one patient was efficacy non-evaluable), the ORR was 75% (12/16), including 7 CRs and 5 PRs; and the median PFS was 6.7 months (95% CI 1.5, NE).
During the study, all patients experienced TEAEs. The most common TEAEs included anemia, neutropenia, asthenia, decreased appetite, weight loss, and thrombocytopenia. Ten patients (58.8%) experienced Grade≥3 TEAEs. Treatment emergent serious adverse events (TESAEs) occurred in 4 patients (23.5%), of which two were considered treatment related. No patient discontinued due to TEAEs. Most of toxicities were manageable by dose modification and supportive care.
In the study, the chemo-free regimen, Sel plus Tis, showed a favorable response rate and manageable safety profile in R/R ENKTL. This approach may probably reverse drug resistance in ENKTL that has progressed after prior CPI treatment.
