BC Cancer Agency Adds PERJETA®-HERCEPTIN® Combo Pack for Treatment of 
HER2-Positive Metastatic Breast Cancer to the Provincial Formulary 
MISSISSAUGA, ON, Dec. 2, 2013 /CNW/ - People with HER2-positive metastatic 
breast cancer in British Columbia will now be able to access a new treatment 
option through the BC Cancer Agency. The BC Cancer Systemic Therapy Program 
has approved the addition of PERJETA to the BCCA Drug Benefit Listing. The 
regimen of pertuzumab (PERJETA) and trastuzumab (HERCEPTIN) in combination 
with docetaxel is given every three weeks for the first‐line treatment of 
metastatic HER2‐positive breast cancer continuing until disease progression 
or toxicity after docetaxel completion.(1) 
"We're pleased the BC Cancer Agency has added the PERJETA-HERCEPTIN Combo Pack 
to the provincial formulary, giving patients with HER2-positive metastatic 
breast cancer in BC access to a new treatment option in the fight against the 
disease," said Mr. Ronnie Miller, president and CEO, Roche Canada. "For more 
than a decade, Roche has been committed to improving breast cancer treatment 
through innovative research and development and we are very proud to be 
expanding our offering and to continue to provide more treatment options." 
In Canada, breast cancer is the most commonly diagnosed cancer in women.(2) 
It accounts for 26 per cent of all cancer cases, making it the second leading 
cause of death in women.(1 )On average, 3,100 women in BC are diagnosed with 
breast cancer every year.(3) 
Metastatic (also known as advanced, secondary or stage IV) breast cancer, the 
spread of cancer cells from the original site where the cancer first formed to 
other parts of the body, is associated with increased severity and is largely 
incurable.(4,5 )The median survival for a woman with this form of breast 
cancer is two years.(4) 
Women with HER2-positive breast cancer test positive for a protein called 
human epidermal growth factor receptor (HER2).(6) This protein is found in 
high quantities on the outside of HER2-positive breast cancer cells. 
HER2-positive breast cancer represents approximately 10 to 20 per cent of 
human cancers, and without treatment, it is associated with aggressive tumour 
growth and poor clinical outcomes. (5,7,8) Approximately 5,000 women in Canada 
are living with this disease.(9) 
British Columbia was the first province to fund the PERJETA-HERCEPTIN Combo 
PERJETA (pertuzumab), in combination with the current standard of care, 
HERCEPTIN® (trastuzumab) and docetaxel chemotherapy, is approved by Health 
Canada for the treatment of patients with HER2-positive metastatic breast 
cancer who have not received prior anti-HER2 therapy or chemotherapy for 
metastatic disease.(10) 
The Health Canada approval of PERJETA is largely based on the phase III 
CLEOPATRA trial. In the trial, people who received a combination of PERJETA, 
HERCEPTIN and docetaxel chemotherapy, lived a median 6.1 months longer without 
their cancer getting worse (progression-free survival) compared with the 
standard of care, HERCEPTIN plus docetaxel chemotherapy, alone (median PFS 
18.5 versus 12.4 months ; HR=0.62; p<0.0001).(9,11 )Further, the combination 
of PERJETA, HERCEPTIN and docetaxel chemotherapy significantly extended the 
lives of people with previously untreated HER2-positive metastatic breast 
cancer (overall survival) compared to HERCEPTIN, docetaxel chemotherapy and 
placebo. The risk of death was reduced by 34 per cent for people on the 
PERJETA arm of the study, compared to those who received HERCEPTIN and 
docetaxel chemotherapy alone (HR=0.66; p=0.0008).(12) At the time of the 
data analysis, median overall survival had not yet been reached because more 
than half of the patients receiving the PERJETA combination were still 
alive.(11) The combination of PERJETA, HERCEPTIN and chemotherapy is thought 
to provide a more comprehensive blockade of HER signaling pathways.
