AstraZeneca and Merck’s Lynparza reduced the risk of disease progression or death by 70% compared to placebo following response to platinum-based chemotherapy
MISSISSAUGA, ON, May 8, 2019 /CNW/ - AstraZeneca Canada and Merck Canada today announced the Health Canada approval of Lynparza (olaparib) as a monotherapy maintenance treatment of adult patients with advanced BRCA-mutated (BRCAm) high-grade epithelial ovarian, fallopian tube or primary peritoneal cancer who are in response (complete or partial) to first-line platinum-based chemotherapy. Patients must have confirmation of BRCA mutation (identified by either germline or tumour testing) before treatment is initiated.
“Until now, women diagnosed with BRCA-mutated ovarian cancer have had limited options for first-line treatments. The approval of Lynparza is an exciting milestone as it provides a new first-line treatment option that offers the potential of sustained remission,” said Dr. James Bentley, President, The Society of Gynecologic Oncology of Canada. “This new approval reinforces the importance of BRCA testing for all patients with an ovarian and fallopian tube cancer. No woman should be left behind.”
“This is tremendous and welcome news for women diagnosed with BRCA-mutated ovarian cancer,” added Elisabeth Baugh, CEO of Ovarian Cancer Canada. “Survival rates for this disease have remained too low for 50 years, and for roughly the last 20 years, there has been significant challenge in arriving at new treatments. Women have run out of treatment options very quickly. Today’s announcement brings the hope and possibility of saving more lives through new therapies that allow earlier treatment for ovarian cancer patients.”
About the SOLO-1 Trial
The Notice of Compliance was granted based on positive results from the pivotal Phase III SOLO-1 trial, in which Lynparza reduced the risk of disease progression or death by 70% in patients with BRCAm advanced ovarian cancer, who were in complete or partial response to platinum-based chemotherapy compared to placebo (HR 0.30 [95% CI 0.23-0.41], p<0.0001).[i] With a median of 41 months follow-up, median progression-free survival (PFS) in the Lynparza arm was not reached versus 13.8 months with placebo.[ii] The SOLO-1 trial also showed 60% of patients receiving Lynparza remained progression-free at 3 years compared to 27% of patients receiving placebo .iii
The safety profile of Lynparza was consistent with previous clinical trials.[iv] The most common adverse drug reactions (ADRs) (of >20% any grade) were nausea (77%), fatigue (63%), vomiting (40%), anemia (39%), diarrhea (34%), constipation (28%), dysgeusia (26%), neutropenia (23%) and headache (23%).v
This approval is the third regulatory approval for Lynparza in the first-line maintenance setting for BRCAm advanced ovarian cancer, following FDA approval in the US in December 2018 and in Brazil earlier this year.

About Ovarian Cancer in Canada
Ovarian cancer is one of the fifth most common cancers for Canadian women.vii An estimated 2,800 Canadians will be diagnosed with the disease this year, and 1,800 women will die from it.viii The majority of cases are high-grade epithelial ovarian cancer. Approximately 25 per cent of Canadian women with this type of ovarian cancer have an abnormality in their BRCA1/2 genes, which increases their risk of developing ovarian cancer.ix
With genetic testing, women who carry the BRCA gene can determine whether increased observation and preventive action (e.g. removal of the fallopian tubes and/or ovaries) are viable options. Women already diagnosed with BRCA-mutated or high-grade ovarian cancer should speak to their doctor about new treatment options available to them.
