FDA Approves Gazyva (Obinutuzumab) for People With Previously Untreated Chronic Lymphocytic Leukemia (CLL)Gazyva Demonstrated an 84 Percent Reduction in the Risk of Disease Worsening or Death When Combined with Chemotherapy Compared to Chemotherapy Alone
Gazyva is the First Medicine Approved with the FDA’s Breakthrough Therapy Designation
SOUTH SAN FRANCISCO, Calif.--(Healthcare Sales & Marketing Network)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) approved Gazyva™ (obinutuzumab), also known as GA101, in combination with chlorambucil chemotherapy for the treatment of people with previously untreated chronic lymphocytic leukemia (CLL). Gazyva (pronounced gah ZY vuh) is the first medicine approved with the FDA’s Breakthrough Therapy Designation and the fifth cancer medicine from Genentech approved by the FDA in the past three years.
“Gazyva is an important new medicine for people with newly diagnosed chronic lymphocytic leukemia as it more than doubled the time people lived without their disease worsening compared to chlorambucil alone,” said Hal Barron, M.D., chief medical officer and head of Global Product Development. “We have spent 20 years researching blood cancer medicines, and we will continue to study Gazyva to assess its efficacy in other types of blood cancers.”
The FDA granted Gazyva Breakthrough Therapy Designation due to the significance of the positive progression-free survival (PFS) results from the Phase III CLL11 trial and the serious and life-threatening nature of CLL.
Today’s FDA approval is based on the outcomes of the CLL11 trial. The trial showed that people who received Gazyva in combination with chlorambucil chemotherapy had significantly reduced risk of disease progression or death (HR=0.16; p lived significantly longer without their disease getting worse compared to those who received chlorambucil alone (median PFS 23.0 months vs. 11.1 months). The most common Grade 3/4 adverse events for those who received Gazyva in combination with chlorambucil compared to chlorambucil alone were infusion-related reactions during the first infusion (21 percent vs. 0 percent [chlorambucil is an oral medicine]), low platelet count (thrombocytopenia, 11 percent vs. 3 percent) and low count of certain types of white blood cells (neutropenia, 34 percent vs. 16 percent), though this did not result in an increased rate of infections in the Gazyva arm.
Final data from the CLL11 trial investigating the direct comparison between Gazyva in combination with chlorambucil and Rituxan® (rituximab) in combination with chlorambucil (Stage 2) will be presented at the American Society of Hematology’s (ASH) 55th Annual Meeting in December 2013.
Gazyva will be available to people in the United States within approximately two weeks. For those who qualify, Genentech plans to offer patient assistance programs for people taking Gazyva through Genentech Access Solutions. Doctors can contact Genentech Access Solutions at (888) 249-4918. More information is also available at http://www.Genentech-Access.com.
Marketing applications have also been submitted to other regulatory authorities, including the European Medicines Agency (EMA).
About Chronic Lymphocytic Leukemia (CLL)
CLL is one of the most common forms of blood cancer and in 2013, it is expected that there will be nearly 5,000 deaths from CLL in the United States. Most cases of CLL (95 percent) start in white blood cells called B-cells that have a protein called CD20 on their surface.
Gazyva is a new monoclonal antibody designed to attach to CD20, a protein found only on B-cells. It attacks 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 Idec.
Gazyva is now approved in combination with chlorambucil for people with previously untreated chronic lymphocytic leukemia (CLL) and is additionally being investigated in a large clinical program, including multiple head-to-head Phase III studies compared to Rituxan in indolent non-Hodgkin’s lymphoma (NHL) and diffuse large B-cell lymphoma (DLBCL).
Gazyva Efficacy In CLL
The pivotal Phase III CLL11 trial, conducted in cooperation with the German CLL Study Group (GCLLSG), is a multicenter, open-label, randomized three-arm study investigating the efficacy and safety profile of either Gazyva plus chlorambucil or Rituxan plus chlorambucil compared to chlorambucil alone in 781 previously untreated people with CLL and co-existing medical conditions.
The study showed that Gazyva demonstrated a statistically significant 84 percent reduction in the risk of disease worsening or death (PFS; HR=0.16, 95 percent CI 0.11-0.24, p
Gazyva in combination with chlorambucil more than doubled the time people with newly diagnosed CLL lived without their disease getting worse (median PFS: 23.0 vs. 11.1 months).
75.9 percent of people responded to Gazyva plus chlorambucil (overall response rate, or ORR) compared to 32.1 percent with chlorambucil alone.
More than a quarter of the people who received Gazyva in combination with chlorambucil achieved a complete response (CR: 27.8 percent vs. 0.9 percent).
The most common Grade 3/4 adverse events for those who received Gazyva in combination with chlorambucil compared to chlorambucil alone were infusion-related reactions during the first infusion (21 percent vs. 0 percent [chlorambucil is an oral medicine]), low platelet count (thrombocytopenia, 11 percent vs. 3 percent) and low count of certain types of white blood cells (neutropenia, 34 percent vs. 16 percent) though this did not result in an increased rate of infections in the Gazyva arm.
Gazyva Indication Statement
Gazyva™ (obinutuzumab) is a prescription medicine used with the chemotherapy chlorambucil, to treat chronic lymphocytic leukemia (CLL) in adults who have not had previous CLL treatment.
Important Safety Information
Patients must tell their doctor right away about any side effects they experience. Gazyva can cause side effects that can become serious or life-threatening including:
Hepatitis B Virus (HBV) Reactivation: may cause serious liver problems including liver failure and death. If patients have had hepatitis B or are carriers of HBV, receiving Gazyva could cause the virus to become an active infection again. Patients should not receive Gazyva if they have active HBV liver disease. A patient’s doctor will do blood tests to check for HBV infection prior to treatment and will monitor the patient during and for several months following their treatment.
Progressive Multifocal Leukoencephalopathy (PML): a serious brain infection that can lead to severe disability and death and for which there is no known prevention, treatment, or cure. Symptoms can include difficulty thinking, loss of balance, changes in speech or walking, weakness on one side of the body, or blurred or lost vision.
