SOUTH SAN FRANCISCO, CA, USA I August 27, 2017 I Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) and granted Priority Review for Gazyva® (obinutuzumab) in combination with chemotherapy followed by Gazyva alone for people with previously untreated follicular lymphoma, one of the most common blood cancers among adults. Follicular lymphoma, a slow-growing (indolent) form of non-Hodgkin’s lymphoma, is incurable and characterized by cycles of remission and relapse.
“Follicular lymphoma becomes harder to treat each time it returns, and the goal of initial treatment is to prevent the cancer from progressing for as long as possible,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “Based on the GALLIUM study, Gazyva-based treatment significantly improved progression-free survival over the current standard of care, and we are committed to bringing this potential new option to patients as soon as possible.”
The sBLA is based on results of the GALLIUM study, which is the first Phase III study in previously untreated follicular lymphoma to show superior progression-free survival (PFS) over Rituxan® (rituximab)-based treatment, the current standard of care. Adverse events (AEs) with either Gazyva or Rituxan were consistent with those seen in previous studies.
The FDA is expected to make a decision on approval under Priority Review by December 23, 2017. Priority Review designation is granted to medicines that the FDA has determined to have the potential to provide significant improvements in the safety and effectiveness of the treatment, prevention or diagnosis of a serious disease. Additional submissions of the GALLIUM data to health authorities around the world are ongoing.
About the GALLIUM study
GALLIUM (NCT01332968) is a global Phase III open-label, multicenter, randomized two-arm study examining the efficacy and safety of Gazyva plus chemotherapy followed by Gazyva alone for up to two years, as compared head-to-head against Rituxan plus chemotherapy followed by Rituxan alone for up to two years. Chemotherapies used were CHOP, CVP or bendamustine and were selected by each participating study site prior to beginning enrollment. GALLIUM included 1,401 patients with previously untreated indolent non-Hodgkin’s lymphoma (iNHL), of which 1,202 patients had follicular lymphoma. The primary endpoint of the study was investigator-assessed progression-free survival (PFS) in patients with follicular lymphoma, with secondary endpoints including PFS assessed by independent review committee (IRC) in patients with follicular lymphoma, PFS in the overall study population (iNHL), response rate (overall response, ORR; and complete response, CR), overall survival (OS) and safety. The study is being conducted in cooperation with the GLSG (Germany), the East German Study Group Hematology and Oncology (OSHO; Germany) and the NCRI (United Kingdom). Results after a follow-up period of 41.1 months showed:
- Gazyva-based treatment reduced the risk of disease worsening or death (PFS, as assessed by investigator) by 32 percent compared to Rituxan-based treatment (HR=0.68; 95 percent CI 0.54-0.87; p=0.0016).
- IRC-assessed PFS was consistent with investigator-assessed PFS. As assessed by IRC, Gazyva-based treatment reduced the risk of disease worsening or death by 28 percent compared to Rituxan-based treatment (HR=0.72; 95 percent CI 0.56-0.93; p=0.0018). Median PFS has not yet been reached in either treatment arm.
- The most common Grade 3-5 AEs that occurred more often in the Gazyva arm compared to the Rituxan arm were low white blood cell count (neutropenia, 46.7 percent vs. 39.5 percent), infections (20.3 percent vs. 16.4 percent), infusion-related reactions (IRRs, 12.4 percent vs. 6.7 percent), low platelet count (thrombocytopenia, 6.1 percent vs. 2.7 percent), new tumors (second malignancies, 4.7 percent vs. 2.7 percent) and cardiac events (3.9 percent vs. 2.8 percent).
GALLIUM is the third positive Phase III study for Gazyva, following the CLL11 study in patients with previously untreated chronic lymphocytic leukemia (CLL) and the GADOLIN study in patients with indolent (slow-growing) non-Hodgkin’s lymphoma whose disease progressed during or within six months of prior Rituxan-based therapy.
About Follicular Lymphoma
Follicular lymphoma is the most common indolent (slow-growing) form of non-Hodgkin’s lymphoma (NHL), accounting for about one in five cases of NHL. It is considered incurable and relapse is common. In the United States, it is estimated that more than 14,000 new cases of follicular lymphoma will be diagnosed in 2017.
About Gazyva
Gazyva is an engineered monoclonal antibody designed to attach to CD20, a protein found on certain types of B-cells. It is thought to work by attacking targeted cells both directly and together with the body’s immune system. Gazyva was discovered by Roche Glycart AG, a wholly owned, independent research unit of Roche. In the United States, Gazyva is part of a collaboration between Genentech and Biogen.
Combination studies investigating Gazyva with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are planned or underway across a range of blood cancers.
Gazyva U.S. Indications
Gazyva® (obinutuzumab) is a prescription medicine used:
- With the chemotherapy drug, chlorambucil, to treat chronic lymphocytic leukemia (CLL) in adults who have not had previous CLL treatment.
- With the chemotherapy drug, bendamustine, followed by Gazyva alone for follicular lymphoma (FL) in adults who did not respond to a rituximab-containing regimen, or whose FL returned after such treatment.
