– Longer-term data from pivotal studies of fixed-duration Columvi and Lunsumio continue to show durable responses in people with heavily pre-treated lymphomas –
– New data reinforce the potential of combination regimens in earlier treatment settings and add to the robust body of evidence supporting ongoing Phase III studies –
SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that new data from its CD20xCD3 T-cell engaging bispecific antibody program, including eight oral presentations, were presented at the 65th American Society of Hematology (ASH) Annual Meeting & Exposition, December 9-12, 2023. Based on 32-month and 3-year follow-ups of two pivotal studies for fixed-duration treatments of Columvi® (glofitamab-gxbm) and Lunsumio® (mosunetuzumab-axgb), respectively, data show that remissions were maintained in the majority of patients with heavily pre-treated lymphomas. Additionally, new early-phase data of novel Columvi or Lunsumio combination regimens support ongoing investigation in Phase III studies in earlier lines of diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL).
“Updated data from pivotal studies of Columvi and Lunsumio continue to provide compelling evidence for how fixed-duration therapies can deliver sustained, long-term benefit for people with difficult-to-treat lymphomas,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “Our data at ASH also demonstrate progress in evaluating our bispecific antibodies in earlier stages of disease and additional types of lymphoma so more people can benefit from our therapies.”
Longer follow-up data from pivotal studies of fixed-duration Columvi and Lunsumio show benefit is maintained beyond the end of treatment
Extended follow-up data from the pivotal Phase II NP30179 study of Columvi administered for up to 12 cycles (approximately eight months) in patients with relapsed or refractory (R/R) large B-cell lymphoma (LBCL) who have received at least two prior lines of therapy showed favorable long-term outcomes. After a median follow-up of 32 months, 55% of patients with a complete response (CR) were in remission at 24 months. Most of these patients remained progression-free and alive 18 months after completing the fixed-duration treatment. In patients who had received prior chimeric antigen receptor (CAR) T-cell therapy, the median duration of CR was 22.0 months (95% confidence interval [CI]: 6.7–not reached). No new safety signals were observed since the previous analysis.
Data from a three-year follow-up analysis of the pivotal Phase II GO29781 study of Lunsumio in patients with R/R FL who have received at least two prior lines of therapy were presented. Results showed continued durable responses and a manageable safety profile after treatment (up to approximately 12 months), with 59% of patients completing treatment after eight cycles (approximately five months). 72.7% of patients with a CR were alive and without disease progression 30 months after their first response. In the overall population, median progression-free survival (PFS) was 24 months (95% CI: 12.0–not evaluable [NE]) and overall survival (OS) not yet reached. No new safety signals were observed since the previous analysis.
Additional data presented reinforce the potential of novel combination regimens in earlier treatment settings
Diffuse large B-cell lymphoma
Data from the Phase Ib/II GO40516 study of Lunsumio plus Polivy® (polatuzumab vedotin-piiq) in patients with R/R LBCL were presented and simultaneously published in Nature Medicine. Results showed that at 24 months median follow-up, the median PFS was 11.4 months (95% CI: 6.2–18.7), and median OS was 23.3 months (95% CI: 14.8–NE), highlighting the combination’s potential in R/R LBCL. The overall safety profile of patients with R/R LBCL treated with Lunsumio plus Polivy was manageable. Cytokine release syndrome (CRS) events were generally low grade (Grade 1: 10.2%; Grade 2: 5.1%; Grade 3: 3.1%). Lunsumio in combination with Polivy is being evaluated as an outpatient therapy for patients with R/R DLBCL in the ongoing Phase III SUNMO study.
Results from both arms of the Phase Ib NP40126 study evaluating Columvi in combination with Rituxan® (rituximab), cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), and Columvi in combination with Polivy plus Rituxan, cyclophosphamide, doxorubicin and prednisone (Pola+R-CHP) in previously untreated DLBCL were presented. After a median of 12 months follow-up, data from the Columvi plus Pola+R-CHP arm showed that 91.7% of patients had a CR with no progression observed. Of the patients with a CR, 95.5% were still in remission, with a 12-month PFS rate of 91.5%. Safety profiles were highly consistent with earlier analyses from this study. These data support the ongoing Phase III SKYGLO study in previously untreated DLBCL.
Follicular lymphoma
The Phase II MorningSun study, evaluating a subcutaneous (SC) formulation of Lunsumio in patients with selected B-cell non-Hodgkin’s lymphomas, showed that SC Lunsumio is active and has a manageable safety profile in patients with first-line (1L) low-tumor burden FL. Data showed that 83.3% of patients achieved a complete metabolic response (95% CI: 62.6-95.3), and responses were ongoing at data cut-off. CRS was generally low grade (Grade 1: 36.7%; Grade 2: 6.7%) and occurred in cycle one only. Subcutaneous Lunsumio is also being investigated in combination with oral lenalidomide in 1L FL in the Phase Ib/II CO41942 study. New data demonstrated promising efficacy and manageable safety; data showed that 89.2% of patients achieved a CR, and CRS events were either Grade 1 (47.5%) or 2 (2.5%), all of which were confined to cycles one to two. The data support further investigation of this SC formulation of Lunsumio and highlight its potential as a tailored monotherapy or combination outpatient therapy for FL, including in community practices.
Totality of data presented underscores the strength of Genentech’s broad, industry-leading development program, which aims to address the diverse needs, preferences and experiences of people with blood cancers
Both Columvi and Lunsumio are being investigated in Phase III studies that will expand the understanding of their impact in earlier lines of treatment. This includes the Phase III STARGLO study evaluating Columvi in combination with GemOx in patients with R/R DLBCL who are ineligible for autologlous stem cell transplant; the Phase III SKYGLO study evaluating the efficacy and safety of Columvi plus Pola+R-CHP in previously untreated DLBCL; the Phase III GLOBRYTE study evaluating Columvi monotherapy in R/R mantle cell lymphoma; the Phase III SUNMO study investigating Lunsumio plus Polivy in R/R DLBCL; and the Phase III CELESTIMO study investigating Lunsumio plus lenalidomide in patients with R/R FL.
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.

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 Seagen 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.
Important Safety Information
Possible serious side effects
Everyone reacts differently to Polivy therapy, so it’s important to know what the side effects are. Some people who have been treated with Polivy have experienced serious to fatal side effects. Your doctor may stop or adjust your treatment if any serious side effects occur. Be sure to contact your healthcare team if there are any signs of these side effects.
- Nerve problems in your arms and legs: This may happen as early as after your first dose and may worsen with every dose. Your doctor will monitor for signs and symptoms, such as changes in your sense of touch, numbness or tingling in your hands or feet, nerve pain, burning sensation, any muscle weakness, or changes to your walking pattern
- Infusion-related reactions: You may experience fever, chills, rash, breathing problems, low blood pressure, or hives within 24 hours of your infusion
- Low blood cell counts: Treatment with Polivy can cause severe low blood cell counts. Your doctor will monitor your blood counts throughout treatment with Polivy
