Pivotal Phase III POLARIX trial comparing Polivy in combination with chemotherapy regimen R-CHP versus the standard of care R-CHOP in treatment of first-line diffuse large B-cell lymphoma (DLBCL) met its primary endpoint of investigator assessed progression-free survival

Prolonging survival without disease advancement could be transformative for newly diagnosed DLBCL patients, as currently 40% of patients relapse after disease progression

Data will be submitted to health authorities globally as soon as possible and presented at an upcoming medical meeting

SOUTH SAN FRANCISCO, CA, USA I August 8, 2021 I Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the pivotal Phase III POLARIX trial investigating Polivy ® (polatuzumab vedotin) in combination with Rituxan® (rituximab) plus cyclophosphamide, doxorubicin and prednisone (R-CHP) versus Rituxan plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) met its primary endpoint by demonstrating significantly improved and clinically meaningful progression-free survival in people with previously untreated diffuse large B-cell lymphoma (DLBCL). Safety outcomes were consistent with those seen in previous trials.

“Since 40% of people with DLBCL relapse after initial therapy, achieving meaningful treatment effects in the front-line setting has the potential to be transformative,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “This Polivy regimen is the first in two decades to improve progression-free survival in DLBCL compared to the standard of care, and we look forward to sharing these results with health authorities to bring this important potential new treatment option to patients as soon as possible.”

Today’s POLARIX results will be presented at an upcoming medical meeting and submitted to health authorities as part of Genentech’s commitment to transforming the treatment of DLBCL by providing options tailored to patient and healthcare professional needs. Genentech would like to thank all investigators, academic partners and people with DLBCL who participated in the study.

Currently, Polivy is used as an off-the-shelf, fixed-duration treatment option in the relapsed or refractory (R/R) DLBCL setting, and is approved in combination with bendamustine and Rituxan for the treatment of R/R DLBCL in more than 60 countries worldwide, including in the EU and in the U.S. Genentech continues to explore areas of unmet need where Polivy has the potential to deliver benefit, with ongoing studies investigating combinations of Polivy with the CD20xCD3 T cell-engaging bispecific antibodies mosunetuzumab and glofitamab, with Venclexta® (venetoclax), which is being developed by AbbVie and Genentech, and with Rituxan in combination with gemcitabine and oxaliplatin in the Phase III POLARGO study.

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) 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 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 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.

About DLBCL
DLBCL is the most common form of non-Hodgkin’s lymphoma (NHL), accounting for about one in three cases of NHL. DLBCL is an aggressive (fast-growing) type of NHL. While it is generally responsive to treatment in the frontline, as many as 40% of patients will relapse or have refractory disease, at which time salvage therapy options are limited and survival is short. Approximately 150,000 people worldwide are estimated to be diagnosed with DLBCL each year.

Polivy U.S. Indication
Polivy is a prescription medicine used with other medicines, bendamustine and a rituximab product, to treat diffuse large B-cell lymphoma in adults who have progressed after at least two prior therapies.

The accelerated approval of Polivy is based on a type of response rate. There are ongoing studies to confirm the clinical benefit of Polivy.
