Updated Linvoseltamab Data Showcase Continued Deepening of Responses in Patients with Heavily Pre-Treated Multiple Myeloma

On June 16, 2024 Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) reported that 14-month median follow-up data from the pivotal Phase 1/2 LINKER-MM1 trial of linvoseltamab in patients with relapsed/refractory (R/R) multiple myeloma (MM) were shared during an oral presentation at the European Hematology Association (EHA) (Free EHA Whitepaper) Congress 2024 and published in the Journal of Clinical Oncology (Press release, Regeneron, JUN 16, 2024, View Source [SID1234644354]). These longer-term results show a deepening of responses following the 11-month median follow-up data presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April. Linvoseltamab is an investigational bispecific antibody designed to bridge B-cell maturation antigen (BCMA) on multiple myeloma cells with CD3-expressing T cells to facilitate T-cell activation and cancer-cell killing.

"Previous results from LINKER-MM1 have demonstrated that linvoseltamab has compelling efficacy characterized by deep and durable responses. With 14-months of median follow-up, 50% of patients achieved a complete response or better, despite their cancer being refractory to or relapsing on standard therapies," said Suzanne Lentzsch, MD, PhD, Director of the Multiple Myeloma and Amyloidosis Program at Columbia University. "Additionally, a study using US-based electronic health record data to indirectly compare linvoseltamab to real-world standard-of-care treatment also support the overall body of evidence for this investigational medicine in heavily pretreated multiple myeloma. Collectively, these presentations underscore the exciting potential of linvoseltamab as we await decisions from regulatory authorities."

The 14-month median follow-up LINKER-MM1 data for linvoseltamab among patients treated at the 200 mg dose (N=117) reinforce the durability and increasing depth of response shown in previous data cuts. Per the presentation and publication, results showed:

71% objective response rate (ORR), with 50% of patients achieving a complete response (CR) or better and 63% achieving a very good partial response (VGPR) or better, as determined by an independent review committee.
Median duration of response (DoR) of 29 months for all responders, while median DoR was not reached for those who achieved a CR or better. In analyses that were not pre-specified, there was an 81% and 95% estimated probability of maintaining a response at 12 months after achieving a partial response or better among all patients and those who achieved a CR or better, respectively.
Median progression-free survival (PFS) was not reached. There was a 70% estimated probability of being progression free at 12 months among all patients; the estimated probability was 96% among those who achieved a CR or better, per an analysis that was not pre-specified.
Median overall survival (OS) of 31 months for all patients (95% CI: 22 months to NE). In analyses that were not pre-specified, the median OS was not reached for patients who achieved a CR or better, and there was a 75% and 100% estimated probability of survival at 12 months among all patients and those who achieved a CR or better, respectively.
High rates of CRs or better in prespecified subgroups, including 55% (17 of 31 patients) among those aged 75 years or older, 48% (22 of 46 patients) among those with high cytogenetic risk, 45% (9 of 20 patients) among Black or African American patients, and 28% (10 of 36 patients) among those with plasmacytomas (including extramedullary and paramedullary).
Safety data at the 14-month median follow-up was generally consistent with those at the 11-month median follow-up. Cytokine release syndrome (CRS) was the most commonly occurring treatment-emergent adverse event (TEAE) and was observed in 46% of patients; 35% were Grade 1, 10% were Grade 2 and one case (1%) was Grade 3. Adjudicated immune effector cell-associated neurotoxicity syndrome (ICANS) events of any grade occurred in 8% of patients, including three cases that were Grade 3 and no cases that were ≥Grade 4. Infections occurred in 74% of patients – including 36% that were Grade 3 or 4 – and decreased in frequency and severity after 6 months. The most common Grade 3 or 4 TEAEs (≥20%) were neutropenia (42%) and anemia (31%). Six deaths considered due to TEAEs by investigators occurred on treatment or within 30 days of the last treatment dose; five were due to infection, and one was due to renal failure.

Also shared at EHA (Free EHA Whitepaper) was a retrospective study comparing outcomes of linvoseltamab 200 mg Phase 2 patients (N=105) in LINKER-MM1 at 14-months of median follow-up to those of real-world external control patients (N=101) who received standard-of-care (SOC) treatment in clinical practice (approximately 80 varied regimens). Patients receiving SOC treatment also met similar inclusion/exclusion criteria to the LINKER-MM1 trial. Comparing linvoseltamab to SOC treatment, the ORR was 70% versus 32% (odds ratio [OR] 5.4), median PFS was 20 months versus 3 months (hazard ratio [HR]: 0.23), and median OS was not reached versus 12 months (HR: 0.40).

In the U.S., linvoseltamab has been granted Fast Track Designation and was accepted for Priority Review for the treatment of R/R MM by the U.S. Food and Drug Administration with a target action date of August 22, 2024. Linvoseltamab is also under review for R/R MM by the European Medicines Association.

The Phase 3 confirmatory trial (LINKER-MM3) for linvoseltamab in patients with R/R MM is ongoing. Linvoseltamab is currently under clinical development, and its safety and efficacy have not been fully evaluated by any regulatory authority.

About Multiple Myeloma
As the second most common blood cancer, there are over 176,000 new cases of MM diagnosed globally, and 35,000 cases are diagnosed in the U.S. every year. In the U.S., there are approximately 8,000 people who have MM that has progressed after three lines of therapy, and 4,000 whose disease has progressed after four or more therapies. The disease is characterized by the proliferation of cancerous plasma cells (MM cells) that crowd out healthy blood cells in the bone marrow, infiltrate other tissues and cause potentially life-threatening organ injury. Despite treatment advances, MM is not curable and while current treatments are able to slow progression of the cancer, most patients will ultimately experience cancer progression and require additional therapies.

About the Linvoseltamab Phase 1/2 Trial and Clinical Development Program
The ongoing, open-label, multicenter Phase 1/2 dose-escalation and dose-expansion LINKER-MM1 trial is investigating linvoseltamab in 282 enrolled patients with relapsed/refractory MM. The Phase 1 dose-escalation portion of the trial – which is now complete – primarily assessed safety, tolerability and dose-limiting toxicities across nine dose levels of linvoseltamab and explored different administration regimens. The ongoing Phase 2 dose expansion portion is assessing the safety and anti-tumor activity of linvoseltamab, with the primary endpoint of ORR. Key secondary endpoints include DoR, PFS, rate of minimum residual disease (MRD) negative status and OS.

Eligibility in the Phase 2 portion requires patients to have received at least three prior lines of therapy or have triple-class refractory MM. Linvoseltamab is administered with an initial step-up dosing regimen followed by the full 200 mg dose administered weekly. At week 16, all patients transition to every two-week dosing. A response-adapted regimen further enables patients to shift to every four-week dosing if they achieve a VGPR or better and have completed at least 24 weeks of therapy. The regimen requires a total of two 24-hour hospitalizations for safety monitoring.

The broader linvoseltamab clinical development program includes additional trials in earlier lines of therapy and stages of disease that are planned or underway. They include a Phase 1/2 trial in first-line MM, a Phase 2 trial in high-risk smoldering MM, and a Phase 2 trial in monoclonal gammopathy of undetermined significance. A Phase 1 trial of linvoseltamab in combination with a Regeneron CD38xCD28 costimulatory bispecific in MM is also planned.

Results were reported for sHLH patients in the ongoing Phase 1b clinical study, which has enrolled a majority of patients with the deadliest sHLH subtype, malignancy-associated HLH (mHLH). In treatment naive mHLH patients, ELA026 achieved a 100% overall response rate (ORR) by week 4 and improved survival at two months compared to natural history studies. ELA026 also demonstrated a high response rate across a range of sHLH patients and a favorable safety profile in this patient population.

ELA026 is a first-in-class monoclonal antibody that targets signal regulatory protein (SIRP)-α/β1/γ on the cell surface of myeloid cells and T lymphocytes, the pathological immune cells that induce hyperinflammation in sHLH. The Phase 1b study is an ongoing open-label, multi-dose, single-arm, multicenter study designed to evaluate the safety and efficacy of ELA026, assess biomarkers, and identify a dose for Phase 2/3 testing (ClinicalTrials.gov identifier: NCT05416307).

"These data show very promising results for ELA026 as a potential treatment for sHLH, which is a challenging disease that is devastating for patients and has no approved treatment options," said Swaminathan P. Iyer, MD, Professor in the Department of Lymphoma/Myeloma at The University of Texas MD Anderson Cancer Center. "Notably, the analysis reveals improved survival was achieved with ELA026 in treatment-naïve mHLH patients, suggesting benefit from early treatment intervention for patients with this rapidly progressing disease."

Study Results Presented at EHA (Free EHA Whitepaper) 2024 Congress
The oral presentation at EHA (Free EHA Whitepaper)2024, entitled "ELA026 Targeting of SIRP(+) Immune Cells Results in a High Response Rate and Improved 2-Month Survival of Treatment-naïve Malignancy-associated Hemophagocytic Lymphohistiocytosis in a Phase 1 Study," was presented by the lead author, Abhishek Maiti, MD, Assistant Professor in the Department of Leukemia at The University of Texas MD Anderson Cancer Center. The data describe analysis of sHLH patients in three cohorts of the ongoing Phase 1b clinical study, including the following highlights:

A majority of enrolled patients had malignancy-associated HLH (mHLH) which has the poorest prognosis, with a mortality rate of approximately 50% at two months. 1
ELA026 was observed to have a favorable safety profile, with manageable adverse events, in this patient population.
In Cohorts 1 and 2, which have completed enrollment (n=12), ELA026 achieved an overall response rate (ORR) of 75% by week 4. Enrollment in Cohort 3 is ongoing (n=5 as of April 17, 2024).
Across all cohorts, 8 patients had treatment-naïve mHLH; in this group, ELA026 achieved an ORR of 100% by week 4 and survival was 88% at two months.
In the study, pharmacodynamic and biomarker responses correlated with clinical responses.
The Phase 1b study has expanded to include up to 20 patients in Cohort 3 and will continue to evaluate ELA026 in frontline treatment settings in patients with various subtypes of sHLH.
"We are delighted that the results of the clinical study of ELA026 in sHLH were recognized and selected as a late-breaking presentation at EHA (Free EHA Whitepaper). This interim data is extremely encouraging, particularly with the high response rates and improved survival at two months achieved in treatment-naïve mHLH patients, and suggests ELA026’s promise as a first-line treatment. Survival at two months is a clinically meaningful benefit for this patient population and demonstrates the ability of ELA026 to rapidly extinguish the hyperinflammation in sHLH, enabling mHLH patients to pursue curative therapies for their underlying cancer," said Kim‑Hien Dao, DO, PhD, Chief Medical Officer at Electra. "We look forward to continuing enrollment in this study and advancing the clinical program to further assess the safety and efficacy of ELA026 in sHLH patients who currently have no approved therapies."

About Secondary Hemophagocytic Lymphohistiocytosis (sHLH)
Secondary hemophagocytic lymphohistiocytosis (sHLH) is a rare, life-threatening inflammatory disease for which there is no approved treatment. It can be triggered by cancer (malignancy-associated HLH, or mHLH), infection, autoimmune disease, or immunotherapy. sHLH is associated with a systemic inflammatory response for which patients require immediate intervention. Without treatment, patients may experience multiple organ failure and death. sHLH has a high mortality rate during the first months of diagnosis, with mHLH patients having the poorest outcomes.

CARsgen Presents First-in-human Results of GPRC5D Targeting CAR-T CT071 at EHA 2024

On June 15, 2024 CARsgen Therapeutics Holdings Limited (Stock Code: 2171.HK), a company focused on innovative CAR T-cell therapies for the treatment of hematologic malignancies and solid tumors, reported that the initial results from the ongoing first-in-human study of CT071 have been presented at the 29th Annual Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) (Press release, Carsgen Therapeutics, JUN 15, 2024, View Source [SID1234644361]).

The preliminary results of Phase I of CT071 (NCT05838131) were presented as a poster at the 29th EHA (Free EHA Whitepaper) Annual Congress on June 14, 18:00 – 19:00 CEST, which was titled "First-in-human study of GPRC5D-targeted CAR T cells (CT071) with an accelerated manufacturing process in patients with relapsed/ refractory multiple myeloma (RRMM)".[1]

"Multiple myeloma is a common yet incurable hematologic malignancy with high unmet need. Despite the numerous recent advances, most patients relapse and become refractory to available therapies and therefore, novel therapies are needed. GPRC5D, a protein highly expressed on the surface of malignant plasma cells with limited expression on normal tissues, represents a promising target for treating multiple myeloma. CT071 is a fully human GPRC5D-targeting autologous second-generation CAR T-cell product manufactured using our expedited CARcelerateTM platform that shortens the manufacturing time to around 30 hours, supporting a shorter vein-to-vein time and younger T cells. The preliminary results of the ongoing study presented at EHA (Free EHA Whitepaper) shows that CT071 has the potential to be the best-in-class GPRC5D targeting CAR-T therapy," said Raffaele Baffa, M.D., Ph.D., Chief Medical Officer of CARsgen Therapeutics. "We are excited about advancing CT071 and look forward to sharing future updates with the medical community."

As of February 28, 2024, 10 patients were dosed with CT071—7 patients at 1.0×105 cells/kg and 3 patients at 3.0×105 cells/kg. Among them, 80% had high-risk cytogenetics, 30% had one or more extramedullary plasmacytomas (EMD), and 40% were at R-ISS stage III. This was a heavily pre-treated population with a median of 5 prior lines of therapy, including 90% double-class refractory, 70% triple-class refractory, 40% penta-drug refractory, 50% having received autologous stem cell transplantation, and 20% had previously been treated with BCMA/CD19 dual-targeting CAR T cells. None of the patients on the study required bridging therapy due to rapid manufacturing turnaround.

The median follow-up at the time of data cut-off was 4.07 months (range: 2.8-7.4). There were no Grade 3 or higher cytokine release syndrome (CRS) events. No immune effector cell-associated neurotoxicity syndrome (ICANS) was observed. No adverse events of special interest or dose limiting toxicity (DLT) occurred. Four patients experienced treatment-related SAE, including pneumonia (n=1), decreased appetite (n=1) and thrombocytopenia (n=2), and all recovered.

The overall response rate was 90%, including 5 patients (50%) with stringent complete response (sCR), 2 patients (20%) with very good partial response (VGPR), and 2 patients (20%) with partial response (PR). All the 9 patients with evaluable MRD assessment at Week 4 achieved MRD negativity (10-6 threshold) ), including all 5 patients with sCR/CR. The pharmacokinetic analysis demonstrated robust cell expansion and persistence, with median Tmax of 14 days (range: 12-28) and median Cmax of 32280.5 copies/μg gDNA (range: 8372-106060).

About CT071

Presentation Title: Eque-cel, A Novel Fully Human BCMA-Targeting CAR-T Therapy in Patients with High Risk Newly Diagnosed Multiple Myeloma

Presentation Type: Oral report

Session Date and Time: June 15, 2024, 16:30 – 17:45 (Central European Summer Time)

Location: Madrid, Spain

Publication Number: S206

Presenter: Professor Bing Chen, Nanjing Drum Tower Hospital

The FUMANBA-2 study is a multicenter, open-label, phase I, single-arm study initiated by researchers, with the principal investigators being Professor Lijuan Chen from Jiangsu Province Hospital and Professor Bing Chen from Nanjing Drum Tower Hospital. This study aims to assess the efficacy, safety, and pharmacokinetics/pharmacodynamics characteristics of Eque-cel for the treatment of high-risk NDMM. Subjects must complete four cycles of induction treatment before the infusion of Eque-cel. After the third induction treatment cycle, patients deemed unsuitable for autologous hematopoietic stem cell transplantation (ASCT) by the researcher will undergo peripheral blood mononuclear cell collection and subsequently receive Eque-cel treatment, with an infusion dose of 1×106 CAR-T/kg.

The primary endpoints were the proportion of minimal residual disease (MRD) negative subjects and progression-free survival (PFS), and secondary endpoints included overall response rate (ORR), duration of response (DOR), safety, and pharmacokinetics/pharmacodynamics (PK/PD).

As of January 25th, 2024, 16 subjects received Eque-cel therapy. High-risk cytogenetics were detected in all subjects, including 62.5 percent double-hit and 12.5 percent triple-hit. 25 percent subjects had extramedullary disease. 37.5 percent subjects had R-ISS stage III disease, among whom 6.3 percent with double-hit and 6.3 percent with triple-hit.

Efficacy: After the infusion of Eque-cel, the median follow-up time was 7.46 months (range: 2.8-18.1), the median PFS had not been reached, the 12-month PFS rate was 84.4% (95% CI: 49.31-96.00), all subjects achieved MRD negativity, of which 71.4% (95% CI: 25.8-92.0) maintained MRD negativity for more than 12 months; the overall response rate (ORR) was 100%, with 93.8% achieving stringent complete response (sCR).

Safety: After the infusion of Eque-cel, the incidence of grade 1-2 cytokine release syndrome (CRS) was 68.8%, no grade 3 or above CRS was observed, and no immune effector cell-related neurotoxicity syndrome (ICANS) or other neurological toxicities occurred. The median time of CRS occurrence was the 7th day after infusion (range: 2-9 days), and the median duration of CRS was 3 days (range: 1-8 days). The most common grade 3 or above drug-related adverse event wase blood cell count reduction, and the incidence of grade 3 or above infectious disease adverse events was 25.0%.

PK/PD: The median peak time of CAR copy number in peripheral blood was 10 days after infusion (range: 7-21 days), with a median peak level of 79,681.299 copies/μg DNA. 81.25% of subjects achieved clearance of free B-cell maturation antigen (sBCMA) within one month after infusion; the median peak time of cytokine detection IL-6 and CRP after infusion were the 7th and 10th day, respectively, and the serum ferritin level did not change significantly.

Professor Lijuan Chen from Jiangsu Province Hospital stated: " Eque-cel, as a novel fully human BCMA CAR-T therapy, has shown encouraging efficacy and safety in high-risk patients with newly diagnosed multiple myeloma who are ineligible for transplantation. This is the world’s first report on CAR-T therapy being used as a first-line treatment in this specific patient population. For NDMM patients who are not suitable for transplantation, the application of CAR-T therapy as a first-line treatment is expected to further improve the remission rate, extend survival, and improve patient prognosis compared to traditional chemotherapy and other targeted drug treatments. This allows us to see the application potential of Eque-cel in the front-line treatment of MM. Advancing CAR-T therapy to the first line will provide patients with more diverse and promising treatment options. With further research and the continuous improvement of treatment strategies, we look forward to CAR-T therapy benefiting more patients in the future."

Professor Bing Chen from Nanjing Drum Tower Hospital stated: "High-risk newly diagnosed multiple myeloma patients have a poor prognosis in standard first-line treatment. For high-risk NDMM patients who do not meet the conditions for ASCT, Eque-cel has shown superior efficacy and safety, achieving deep and sustained remission, with all patients achieving MRD negativity. This opens up a new approach to reverse the poor prognosis of high-risk myeloma patients. Moreover, compared with relapsed/refractory multiple myeloma (RRMM) patients, the incidence and severity of CRS in high-risk NDMM patients treated with Eque-cel are lower, showing a more favorable safety profile. We will further investigate the clinical benefits of Eque-cel for high-risk newly diagnosed multiple myeloma patients with longer follow-up."

Genentech’s Phase III STARGLO Study Demonstrates Columvi Significantly Extends Survival in People With Relapsed or Refractory Diffuse Large B-Cell Lymphoma

On June 15, 2024 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported statistically significant and clinically meaningful results from its Phase III STARGLO study of Columvi (glofitamab-gxbm) in combination with gemcitabine and oxaliplatin (GemOx) versus Rituxan (rituximab) in combination with GemOx (R-GemOx) for people with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who have received at least one prior line of therapy and are not candidates for autologous stem cell transplant, or who have received two or more prior lines of therapy (Press release, Genentech, JUN 15, 2024, View Source [SID1234644356]). Data were featured in the congress Press Briefing and presented today in the Plenary Abstracts Session at the European Hematology Association (EHA) (Free EHA Whitepaper) 2024 Congress as a late-breaking oral presentation.

"The results from STARGLO are the first to show the potential of a CD20xCD3 bispecific antibody to make a difference in second or later-line DLBCL in people who are ineligible for transplant and have limited options," said Jeremy Abramson, M.D., director, Jon and Jo Ann Hagler Center for Lymphoma at the Massachusetts General Hospital Cancer Center, and principal investigator of the STARGLO study. "Glofitamab in combination with GemOx showed clinically significant improvement in overall survival, as well as key secondary endpoints, and the benefits were reinforced with an additional 11 months of follow-up."

The primary analysis (median follow-up of 11.3 months) confirmed that the study met its primary endpoint of overall survival (OS), demonstrating that patients treated with Columvi plus GemOx lived significantly longer, with a 41% reduction in the risk of death (hazard ratio [HR]=0.59, 95% CI: 0.40-0.89, p=0.011) versus R-GemOx. Median OS was not reached with the Columvi regimen versus nine months for R-GemOx. Safety of the combination appeared consistent with the known safety profiles of the individual medicines.

Pre-specified exploratory subgroup analyses showed comparable results, including consistency across the clinically relevant stratification factors of line of therapy (second-line versus third-line+) and outcome of last therapy (relapsed versus refractory). Regional inconsistencies were observed, however interpretation is limited given the exploratory nature of these analyses and small subgroups with wide confidence intervals.

"This marks a first step in advancing Columvi combinations in earlier settings to address the urgent need for the 40% of people who will relapse or have refractory disease and who have limited options," said Levi Garraway, M.D., Ph.D., Genentech’s chief medical officer and head of Global Product Development. "Moreover, patients do not have to wait to start treatment with Columvi. This could be particularly important for patients with highly aggressive disease who are at risk of rapid disease progression."

The Columvi combination also met its key secondary endpoints, with a 63% reduction in risk of disease worsening or death (progression-free survival, PFS) compared to R-GemOx (HR=0.37; 95% CI: 0.25–0.55, p<0.0001). A follow-up analysis was conducted after all patients had completed therapy (median follow-up of 20.7 months), which showed continued benefit in both primary and secondary endpoints. Median OS for people treated with the Columvi combination was 25.5 months, nearly double what was seen for people treated with R-GemOx at 12.9 months, and more than twice as many patients experienced a complete response (58.5% versus 25.3%, respectively).

Adverse event (AE) rates were higher with the Columvi combination versus R-GemOx, noting higher median number of cycles received with Columvi combination (11 versus 4). One of the most common AEs was cytokine release syndrome, which was generally low grade (Any Grade: 44.2%, Grade 1: 31.4%, Grade 2: 10.5%, Grade 3: 2.3%) and occurred primarily in Cycle 1.

Columvi is the first CD20xCD3 bispecific antibody to demonstrate a survival benefit in DLBCL in a randomized Phase III trial, demonstrating the potential of this type of therapeutic combination to improve survival outcomes in earlier lines of treatment. The standard second-line therapy for R/R DLBCL patients has historically been high-dose chemotherapy followed by stem-cell transplant, however, not everyone with R/R DLBCL is a candidate due to age or coexisting medical conditions. Newer therapies are also becoming available, but barriers remain for many, and alternative treatment options are needed for these patients. Columvi is given as a fixed-duration treatment, offering people with R/R DLBCL a treatment end date and the possibility of a treatment-free period, unlike continuous treatments.

Results from the STARGLO study will be submitted to global health authorities, including the U.S. Food and Drug Administration (FDA) and the European Medicines Agency.

Columvi is also being investigated in other aggressive, hard-to-treat lymphomas and was recently granted Breakthrough Therapy Designation by the FDA for the treatment of adult patients with relapsed or refractory mantle cell lymphoma who have received at least two prior therapies based on results from the Phase I/II NP30179 study.

About the STARGLO Study

The STARGLO study [GO41944; NCT04408638] is a Phase III, multicenter, open-label, randomized study evaluating the efficacy and safety of Columvi (glofitamab-gxbm) in combination with gemcitabine plus oxaliplatin (GemOx) versus Rituxan (rituximab) in combination with GemOx in patients with relapsed or refractory diffuse large B-cell lymphoma who have received at least one prior line of therapy and are not candidates for autologous stem cell transplant, or who have received two or more prior lines of therapy. Outcome measures include overall survival (primary endpoint), progression-free survival, complete response rate, objective response rate, duration of objective response (secondary endpoints), and safety and tolerability.

STARGLO is intended as a confirmatory study to convert Columvi’s accelerated approval in the U.S. and conditional marketing authorization in the EU to full approvals for people with R/R DLBCL after two or more lines of systemic therapy based on the pivotal Phase I/II NP30179 study.

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. A clinical development program for Columvi is ongoing, investigating the molecule as a monotherapy and in combination with other medicines for the treatment of people with B-cell non-Hodgkin’s lymphomas, including diffuse large B-cell lymphoma and other blood cancers.

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.
