"POLARIX was the first trial to elevate treatment standards for frontline diffuse large B-cell lymphoma in 20 years and we are additionally encouraged by the five-year follow-up results," said Levi Garraway, M.D., Ph.D., Genentech’s chief medical officer and head of Global Product Development. "More than 38,000 people worldwide have been treated with Polivy in combination with R-CHP and these data continue to underscore its potential to improve outcomes for people diagnosed with this aggressive lymphoma."
Follow-up exploratory analysis after five-years indicated a positive trend in overall survival (OS) in the intent-to-treat (ITT) population in favor of Polivy in combination with R-CHP compared to Rituxan plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). Results showed a trend in reduction in the risk of death (HR 0.85; 95% CI: 0.63–1.15) for people with previously untreated DLBCL with the Polivy combination, an improvement on the three-year follow-up data (HR 0.94; 95% CI: 0.67–1.33). The five-year analysis of POLARIX indicates that the full difference in OS between treatment arms has yet to be observed and an additional two years of follow-up will continue.
"Diffuse large B-cell lymphoma is a notoriously challenging cancer to treat, however, Polivy in combination with R-CHP has shown to be a critical advance for patients by helping to reduce relapse and disease progression," said Gilles Salles, M.D., Ph.D., chief of Lymphoma Service, Division of Hematological Malignancies, Memorial Sloan Kettering Cancer Center, New York. "The survival trend seen in this follow-up analysis reinforces the potential impact of frontline treatment with Polivy in combination with R-CHP and its role as a standard of care therapy."
In addition to the positive trend in OS, an observational analysis suggested nearly 25% fewer follow-up treatments such as radiation, systemic chemotherapy and CAR-T cell therapy were needed in patients receiving Polivy in combination with R-CHP compared to those treated with R-CHOP (38.3% versus 61.7%).
At five years of follow-up, benefits in progression-free survival and disease-free survival with Polivy in combination with R-CHP were maintained, consistent with the three-year follow-up data, reinforcing the potential of Polivy in combination with R-CHP to provide durable and lasting remissions. The latest follow-up data also showed a numerical reduction in death related to patients’ lymphoma in those treated with Polivy in combination with R-CHP compared to those treated with R-CHOP (9.0% versus 11.4%). The safety profile remains consistent with the known profiles of the individual study medicines with no new safety signals observed, reinforcing the positive benefit-risk profile of this Polivy combination.
Results from an expanded cohort of 1,000 patients including global and Chinese patients demonstrated comparability to the global ITT population.
Polivy in combination with R-CHP is currently approved for the treatment of first-line (1L) DLBCL in more than 90 countries worldwide including the U.S., countries throughout the EU, the U.K., Japan, Canada and China. Genentech continues to work with health authorities around the world to bring this treatment regimen to even more patients.
Genentech aims to offer various treatment options for DLBCL that meet the diverse needs of patients and healthcare systems. In an effort to elevate treatment standards even further, Genentech is exploring Polivy in combination with other molecules, including its bispecific antibodies. Studies include the Phase III SUNMO trial evaluating the efficacy and safety of subcutaneously administered Lunsumio (mosunetuzumab-axgb) in combination with intravenous (IV) Polivy versus IV Rituxan plus gemcitabine and oxaliplatin (R-GemOx) in second-line or later DLBCL, and the Phase III SKYGLO trial investigating the efficacy of Polivy in combination with R-CHP and Columvi (glofitamab-gxbm) versus Polivy in combination with R-CHP in 1L DLBCL.
About the POLARIX Study
POLARIX [NCT03274492] is an international Phase III, randomized, double-blind, placebo-controlled study evaluating the efficacy, safety and pharmacokinetics of Polivy (polatuzumab vedotin-piiq) plus Rituxan (rituximab), cyclophosphamide, doxorubicin and prednisone (R-CHP) versus Rituxan, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in people with previously untreated diffuse large B-cell lymphoma (DLBCL). Eight-hundred and seventy-nine patients were randomized 1:1 to receive either Polivy plus R-CHP plus a vincristine placebo for six cycles, followed by Rituxan for two cycles; or R-CHOP plus a Polivy placebo for six cycles, followed by two cycles of Rituxan. The primary outcome measure is progression-free survival as assessed by the investigator using the Lugano Response Criteria for malignant lymphoma. POLARIX is being conducted in collaboration with The Lymphoma Study Association (LYSA) and The Lymphoma Academic Research Organisation (LYSARC).
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 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.

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
