New targeted treatment now available for Canadians living with the most common form of slow-growing, non-Hodgkin's lymphoma
MISSISSAUGA, ON, Feb. 7, 2017 /CNW/ - Hoffmann-La Roche Limited (Roche Canada) today announced that Health Canada has approved GAZYVA® (obinutuzumab) in combination with bendamustine followed by GAZYVA monotherapy for the treatment of patients with follicular lymphoma who relapsed after, or are refractory to, a RITUXAN® (rituximab)-containing regimen.1
Each year, an estimated 2,800 Canadians are diagnosed with follicular lymphoma,2 a slow-growing form of non-Hodgkin's lymphoma.3 While chemotherapy and targeted treatments such as RITUXAN – the current standard of care – have improved survival rates for patients impacted by the disease,4 follicular lymphoma often recurs.5
"Despite significant improvements in the treatment of follicular lymphoma including the addition of rituximab to primary chemotherapy and the use of rituximab maintenance, follicular lymphoma remains an incurable disease," said Dr. John Kuruvilla, a hematologist at Princess Margaret Hospital and Associate Professor at the University of Toronto. "New treatment options are needed for Canadians dealing with relapsed or refractory follicular lymphomas. GAZYVA in combination with bendamustine represents an important new advance for patients who have follicular lymphoma that has relapsed after, or was refractory to a rituximab-based treatment regimen."
About the Health Canada Approval of GAZYVA
Health Canada's approval of GAZYVA is based on data from the pivotal Phase III GADOLIN study, which was an open-label, multicenter, randomized, two-arm study enrolling 396 patients, 24 per cent of who (n=99) were Canadian patients enrolled at 10 clinical trials sites across the country. Data from the GADOLIN study demonstrates that treatment with GAZYVA plus bendamustine results in progression-free survival (PFS) for a median of 29.2 months compared to bendamustine alone with a median of 13.7 months based on investigator-assessed PFS.6
"While many Canadians live with follicular lymphoma for several years, there are limited options available today that address the needs of patients who do not respond to their prescribed treatment or their current treatment stops working," said Robin Markowitz, CEO of Lymphoma Canada. "It is exciting to see that research is continuing to drive advances in this space, providing patients with more treatment options to help them combat their disease."
About Follicular Lymphoma
Follicular lymphoma is a form of blood cancer that develops from B-lymphocytes (B-cells). In healthy immune systems, B-cells produce antibodies to help fight off infections. However, in lymphomas, B-cells grow uncontrollably and spread to different organs, including the spleen, lymph nodes and bone marrow.7
The average age of diagnosis is 59 years of age and the condition is slightly more common in women than in men.8
About the GADOLIN Study
GADOLIN is a Phase III open-label, multicenter, randomized, two-arm study evaluating GAZYVA plus bendamustine followed by GAZYVA alone until disease progression or for up to two years compared to bendamustine alone.9
GADOLIN included 396 patients with indolent non-Hodgkin's lymphoma (NHL), including 321 patients with follicular lymphoma, whose disease progressed during or within six months of prior RITUXAN-based therapy.10 The primary endpoint of the study was progression-free survival (PFS) assessed by an independent review committee.11 Secondary endpoints included PFS as assessed by investigator review, best overall response, complete response, partial response, duration of response, overall survival and safety profile.12
Results in follicular lymphoma showed the GAZYVA regimen resulted in a 52 per cent reduction in the risk of disease worsening or death, compared to bendamustine alone.13 The most frequently observed serious adverse events (≥ two per cent) that occurred in patients treated with GAZYVA plus bendamustine were febrile neutropenia, neutropenia, sepsis, infusion related reactions, pyrexia, pneumonia and thrombocytopenia.14
About GAZYVA® (obinutuzumab)
GAZYVA is an engineered monoclonal antibody designed to bind to CD20, a protein found on white blood cells called B cells. It attacks targeted cells both directly and together with the body's immune system.15
GAZYVA is currently approved for use in combination with chlorambucil in more than 70 countries — including Canada — to treat people with previously untreated chronic lymphocytic leukemia.
GAZYVA was studied in a global Phase III open-label, multicenter, randomized, two-arm study called GALLIUM to examine the efficacy and safety of the medicine plus chemotherapy, as compared to RITUXAN plus chemotherapy, followed by GAZYVA or RITUXAN alone for up to two years. It included 1,401 patients with previously untreated indolent non-Hodgkin lymphoma.16
