FDA Advisory Committee Votes in Favor of the Clinical Benefit of Genentech's Polivy Combination for People With Previously Untreated Diffuse Large B-Cell Lymphoma

– U.S. FDA’s Oncologic Drugs Advisory Committee voted 11 to 2 in favor of the clinical benefit of the Phase III POLARIX study of Polivy in combination with R-CHP for people with previously untreated diffuse large B-cell lymphoma

– This is the first treatment in 20 years to show a significant and clinically meaningful improvement in progression-free survival over the standard-of-care for first-line DLBCL

– DLBCL is an aggressive, hard-to-treat disease and the most common form of non-Hodgkin’s lymphoma in the United States

Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee (ODAC) voted 11 to 2 in favor of Polivy® (polatuzumab vedotin-piiq) in combination with Rituxan® (rituximab) plus cyclophosphamide, doxorubicin and prednisone (R-CHP) for the treatment of people with previously untreated diffuse large B-cell lymphoma (DLBCL). The ODAC provides the FDA with independent opinions and recommendations from outside medical experts though the recommendations are not binding. The FDA is expected to make a final decision on its review of the supplemental Biologics License Application (sBLA) for Polivy in this indication by April 2, 2023.

“Today’s committee decision to recognize the potential of this Polivy combination as a first-line treatment option is important since four in 10 people with diffuse large B-cell lymphoma relapse or do not respond to initial treatment,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We believe the clinical benefit demonstrated in the POLARIX study may improve outcomes for many people with newly diagnosed DLBCL and look forward to continued collaboration with the FDA to make this treatment option available in the U.S.”

More than 60 countries have approved this Polivy combination for the treatment of adult patients with previously untreated DLBCL, including in the EU, UK, Japan, Canada and China. Polivy in combination with R-CHP was recently added to the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelines®) as a category 1, preferred regimen for first-line DLBCL.

DLBCL is an aggressive, hard-to-treat disease and is the most common form of non-Hodgkin’s lymphoma in the United States. Limited progress has been made in improving patient outcomes in previously untreated DLBCL over the last two decades. Polivy in combination with R-CHP is the first treatment in 20 years to show a significant improvement in progression-free survival (PFS) over the standard-of-care, Rituxan in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), in this setting.

The sBLA submission is based on pivotal data from the Phase III POLARIX study, which demonstrated a statistically significant and clinically meaningful improvement in PFS with Polivy plus R-CHP compared to standard-of-care R-CHOP in first-line DLBCL. The risk of disease progression, relapse or death was reduced by 27% with Polivy plus R-CHP compared with R-CHOP (hazard ratio [HR] 0.73; 95% confidence interval [CI]: 0.57–0.95; p<0.02). Safety outcomes were consistent with those seen in previous clinical trials, and the safety profile was comparable for Polivy plus R-CHP versus R-CHOP, including rates of Grade 3-4 adverse events (AEs; 57.7% versus 57.5%), serious AEs (34.0% versus 30.6%), Grade 5 AEs (3.0% versus 2.3%), and AEs leading to dose reduction (9.2% versus 13.0%).

Polivy in combination with bendamustine and Rituxan is currently approved in more than 80 countries worldwide for the treatment of adults with relapsed or refractory (R/R) DLBCL after one or more prior therapies, including in the U.S. under FDA accelerated approval.

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 (PFS) 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 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 people 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.

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, 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.

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. A patient’s doctor may stop or adjust a patient’s treatment if any serious side effects occur. Patients must contact their healthcare team if there are any signs of these side effects.

  • Nerve problems in arms and legs: This may happen as early as after the first dose and may worsen with every dose. If a patient already has nerve pain, Polivy may make it worse. The patient’s doctor will monitor for signs and symptoms, such as changes in sense of touch, numbness or tingling in hands or feet, nerve pain, burning sensation, any muscle weakness, or changes to walking patterns
  • Infusion-related reactions: A patient may experience fever, chills, rash, breathing problems, low blood pressure, or hives within 24 hours of the infusion
  • Infections: Patients should contact their healthcare team if they experience a fever of 100.4°F or higher, chills, cough, or pain during urination. Also, a patient’s doctor may give medication before giving Polivy, which may prevent some infections, and monitor blood counts throughout treatment with Polivy. Treatment with Polivy can cause severe low blood cell counts
  • Rare and serious brain infections: A patient’s doctor will monitor the patient closely for signs and symptoms of these types of infections. Patients should contact their doctor if they experience confusion, dizziness or loss of balance, trouble talking or walking, or vision changes
  • Tumor lysis syndrome: Caused by the fast breakdown of cancer cells. Signs include nausea, vomiting, diarrhea, and lack of energy
  • Potential harm to liver: Some signs include tiredness, weight loss, pain in the abdomen, dark urine, and yellowing of the skin or the white part of the eyes. Patients may be at higher risk if they already have liver problems or are taking other medication

Side effects seen most often

The most common side effects during treatment were:

  • Low blood cell counts (platelets, red blood cells, white blood cells)
  • Nerve problems in arms and legs
  • Tiredness or lack of energy
  • Diarrhea
  • Nausea
  • Fever
  • Decreased appetite
  • Infections

Polivy may not be for everyone. A patient should talk to their doctor if they are:

  • Pregnant or may be pregnant: Data have shown that Polivy may harm an unborn baby
  • Planning to become pregnant: Women should avoid getting pregnant while taking Polivy. Women should use effective contraception during treatment and for at least 3 months after their last Polivy treatment. Men taking Polivy should use effective contraception during treatment and for at least 5 months after their last Polivy treatment
  • Breastfeeding: Women should not breastfeed while taking Polivy and for at least 2 months after the last dose
