Health Canada Approves Avastin in Combination with Paclitaxel for First-Line Treatment of Patients with Advanced HER2-Negative Breast Cancer



    
    Avastin is now approved to treat the two most prevalent cancers in
    Canada: Breast and Colorectal Cancer(1)
    

    TORONTO, Feb. 11 /CNW/ - Hoffmann-La Roche Canada (Roche) announced today
that Health Canada has approved Avastin(R) (bevacizumab), in combination with
paclitaxel chemotherapy, for the first-line treatment of patients with
metastatic HER2-negative breast cancer who are ECOG Class 0-1. The approval,
under the policy of Notice of Compliance with Conditions, is based on results
of a phase III study (E2100), which showed the combination of Avastin and
paclitaxel nearly doubled the chance of progression-free survival in patients
with metastatic breast cancer compared to paclitaxel alone.
    "Health Canada's approval of Avastin for first-line metastatic breast
cancer is another important advancement in breast cancer therapy in Canada and
excellent news for patients with the disease," said Dr. Karen Gelmon, medical
oncologist, BC Cancer Agency and Professor of Medicine, University of British
Columbia. "In the study patients on the Avastin-paclitaxel combination therapy
experienced a doubling of their time living without the disease advancing.
This may provide a significant increase in the quality time for patients."
    Products authorized under Health Canada's NOC/c policy are intended for
the treatment, prevention or diagnosis of a serious, life-threatening or
severely debilitating illness. They have demonstrated promising benefit, are
of high quality and possess an acceptable safety profile based on a
benefit/risk assessment. Health Canada has provided access to this product on
the condition that the sponsor submit the results of additional clinical
trials to verify the benefit within an agreed upon time frame.
    "This is exceptionally good news for Canadian women with metastatic
breast cancer," says Diana Ermel, President of the Canadian Breast Cancer
Network. "It represents another advance in breast cancer treatment."
    Roche will undertake additional studies to verify the clinical benefit of
Avastin for HER-2 negative breast cancer patients. Roche will provide Health
Canada with the results of two confirmatory phase III trials: AVADO (Avastin
plus docetaxel chemotherapy vs. docetaxel alone) which has already
demonstrated superior efficacy and safety of the combination, and RIBBON-1. A
full review of both the AVADO and RIBBON-1 data by Health Canada will be
required for the NOC/c to be converted into a full Notice of Compliance.
    Avastin is an anti-angiogenic therapy that inhibits the growth of a
network of blood vessels that supply nutrients and oxygen to cancerous
tissues. It is the first in its class shown to consistently deliver improved
overall and/or progression-free survival benefit for colorectal, lung, breast
and, renal cell cancer patients. Avastin is now approved in Canada to treat
two of the most prevalent forms of cancers in Canada: breast and colorectal
cancers(2), satisfying unmet patient needs. Avastin received accelerated
approval in the United States for the treatment of metastatic breast cancer in
February 2008 and approval in Europe in March 2007.
    Breast cancer is the most common cancer in Canadian women. All women are
exposed to the potential of breast cancer - one out of eight women will
develop breast cancer at some point in her lifetime and 40% of them will end
in metastasis. Breast cancer affects younger women more frequently than all
other cancer types together. In 2008, an estimated 22,400 women were diagnosed
with breast cancer in Canada and approximately 5,300 died from the disease(3).
Globally, breast cancer is the second most common form of cancer and the
second leading cancer killer of women with an estimated annual death toll in
excess of 400,000(4).
    Roche is continuing to study Avastin in early-stage breast cancer as well
as in a variety of other tumour types. Avastin is the second biologic therapy
to be discovered and developed by Genentech/Roche for women with advanced
breast cancer. Roche is committed to providing Canadians with innovative
therapies that do not deteriorate the quality of life.

    About E2100

    The E2100 trial was sponsored by the National Cancer Institute under a
Cooperative Research and Development Agreement and was conducted by a network
of researchers led by the Eastern Cooperative Oncology Group (ECOG). E2100 was
a multicentre, randomized and controlled clinical trial that enrolled 772
patients with previously untreated, locally recurrent or metastatic breast
cancer. Patients were randomized to receive weekly treatment with paclitaxel
every three out of four weeks, with or without Avastin administered once every
two weeks.
    Based on an independent, blinded review of patient scans, patients
treated with Avastin plus paclitaxel experienced a 52 percent reduction in the
risk of disease progression or death compared to those treated with paclitaxel
alone (based on a hazard ratio of 0.48; p (less than)0.0001). In the Avastin
arm, median PFS was 11.3 months versus 5.8 months in the paclitaxel alone arm.
Based on the investigator assessment, patients treated with Avastin plus
paclitaxel experienced a 58 percent reduction in the risk of disease
progression or death compared to those treated with paclitaxel alone (based on
a hazard ratio of 0.42; p (less than)0.0001). The data showed a similar
magnitude of benefit relative to the initial results presented by ECOG at the
American Society of Clinical Oncology annual meeting in 2005 and later
published in the New England Journal of Medicine in 2007. The secondary
endpoint of overall survival was longer in the Avastin-containing arm, as
indicated by the hazard ratio of 0.87 but this improvement did not reach
statistical significance (p=0.14). A one year exploratory analysis of overall
survival was significantly improved with the addition of Avastin, (73.8% vs.
82.3%; p=0.007).
    Overall, the safety profile of AVASTIN seen in the pivotal study was
consistent with the established safety profile seen in previous phase III
studies in other tumor types. A 20% increase in grade 3 and 4 adverse events
was observed in the AVASTIN plus paclitaxel arm compared to paclitaxel alone
which was mainly driven by hypertension. The most serious AEs described in the
Product Monograph1 include gastrointestinal perforations, hemorrhage, arterial
hromboembolism, non-gastrointestinal fistula, hypertensive crises, reversible
posterior leukoencephalopathy syndrome, neutropenia and infections, nephritic
syndrome and congestive heart failure. The most frequently observed AEs with
(greater than)2% difference between treatment arms across clinical trials in
metastatic breast cancer patients receiving AVASTIN, with or without
chemotherapy, were hypertension (very common), fatigue or asthenia, infection,
neutrophil count abnormalities, nausea, vomiting, diarrhoea, dehydration,
headache, peripheral sensory neuropathy and proteinuria.
