– Avastin is now approved for ten distinct uses across six different types of cancer in the United States –
SOUTH SAN FRANCISCO, CA, USA I June 13, 2018 I Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has approved Avastin® (bevacizumab) in combination with chemotherapy (carboplatin and paclitaxel), followed by Avastin as a single agent, for the treatment of women with advanced (stage III or IV) ovarian cancer following initial surgical resection.
“Today’s approval is an important advance for women newly diagnosed with this type of ovarian cancer,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We’re committed to advancing medicines in areas of unmet need and this FDA approval of Avastin plus chemotherapy gives women with advanced ovarian cancer a new treatment option that has been shown to significantly delay disease progression or death.”
“This approval represents an important milestone as the first medicine, other than chemotherapy, for women with advanced ovarian cancer after their initial surgery,” said David Barley, chief executive officer, National Ovarian Cancer Coalition (NOCC). “Ovarian cancer is the fifth leading cause of cancer-related deaths among women in the United States, and this approval underscores Genentech’s dedication to bringing new treatment options to women with gynecological cancers.”
The approval for Avastin, in combination with carboplatin and paclitaxel, followed by Avastin as a single agent, for the treatment of women with stage III or stage IV epithelial ovarian, fallopian tube, or primary peritoneal cancer following initial surgical resection, is based on data from the pivotal Phase III GOG-0218 trial. Women who received Avastin in combination with chemotherapy, and continued use of Avastin alone, had a median progression-free survival (PFS) of 18.2 months compared to 12.0 months in women who received chemotherapy alone (HR=0.62; 95% CI 0.52 - 0.75, p<0.0001). This PFS benefit was achieved with a fixed-duration treatment (up to 22 cycles of Avastin total). Avastin has boxed warnings for GI perforation, surgery and wound healing complications and hemorrhage.
Avastin is now approved for ten distinct uses across six different types of cancer in the United States. This indication represents Avastin’s fourth gynecologic oncology indication in four years, including advanced cervical cancer and two different forms of ovarian cancer that recurred after platinum-based chemotherapy.
About the GOG-0218 Study
GOG-0218 (NCT00262847) is a multi-center, randomized, double-blind, placebo-controlled Phase III study in 1,873 women with previously untreated stage III or IV epithelial ovarian, primary peritoneal, or fallopian tube carcinoma who already had surgery to remove as much of the tumor as possible. Participants were randomized into one of three treatment arms: chemotherapy alone (carboplatin and paclitaxel), Avastin (15 mg/kg) plus chemotherapy followed by placebo alone, or Avastin plus chemotherapy followed by Avastin alone for a total of up to 22 cycles. The primary endpoint of the study was investigator-assessed PFS and secondary endpoints included overall survival (OS). The study was conducted by the Gynecologic Oncology Group (GOG) and initial results were previously published in the New England Journal of Medicine.

|Grade 3-4 adverse events occurring more often (≥2%) in the Avastin with chemotherapy followed by Avastin alone arm or the Avastin with chemotherapy arm versus the chemotherapy alone arm were fatigue (9%, 6%, 6%, respectively), high blood pressure (10%, 6%, 2%), decreased platelet count (21%, 20%, 15%) and decreased white blood cell count (51%, 53%, 50%).|

About Ovarian Cancer
Ovarian cancer causes more deaths among women than any other gynecologic cancer in the United States. In 2018, more than 22,000 women will be diagnosed with ovarian cancer in the U.S. and about 14,000 will die from the disease. About 80% of ovarian cancer cases are found at an advanced stage, when the cancer has spread beyond the ovaries. Early ovarian cancer often does not have any symptoms and when symptoms, such as abdominal swelling, bloating, abdominal pain, difficulty eating or feeling full quickly and/or frequent urination, are present, they can be associated with other less serious conditions. Five-year survival rates worsen dramatically based on stage of diagnosis.

Avastin is a prescription-only medicine that is a solution for intravenous infusion. It is a biologic antibody designed to specifically bind to a protein called vascular endothelial growth factor (VEGF) that plays an important role throughout the lifecycle of the tumor to develop and maintain blood vessels, a process known as angiogenesis. Avastin is designed to interfere with the tumor blood supply by directly binding to the VEGF protein to prevent interactions with receptors on blood vessel cells. The tumor blood supply is thought to be critical to a tumor's ability to grow and spread in the body (metastasize).
- Metastatic colorectal cancer (mCRC) for first- or second-line treatment in combination with intravenous 5-fluorouracil–based chemotherapy. It is also approved to treat mCRC for second-line treatment, when used with fluoropyrimidine-based (combined with irinotecan or oxaliplatin) chemotherapy, after cancer progresses following a first-line treatment that includes Avastin.
- Avastin is not approved for use after the primary treatment of colon cancer that has not spread to other parts of the body
- Advanced nonsquamous non–small cell lung cancer (NSCLC) in combination with carboplatin and paclitaxel, in people who have not received chemotherapy for their advanced disease
- Metastatic kidney cancer (mRCC) when used with interferon alfa
- Glioblastoma (GBM) in adult patients whose cancer has progressed after prior treatment (recurrent or rGBM)
- Advanced cervical cancer (CC) in combination with paclitaxel and cisplatin or paclitaxel and topotecan, is approved to treat persistent, recurrent, or metastatic cancer of the cervix
- Ovarian cancer (OC). Avastin, in combination with carboplatin and paclitaxel, followed by Avastin alone, is used for the treatment of patients with advanced (Stage III or IV) epithelial ovarian, fallopian tube, or primary peritoneal cancer following initial surgery.
Avastin in combination with paclitaxel, pegylated liposomal doxorubicin or topotecan, is approved to treat platinum-resistant recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer (prOC) in women who received no more than two prior chemotherapy treatments.
Avastin, either in combination with carboplatin and paclitaxel or with carboplatin and gemcitabine, followed by Avastin alone, is approved for the treatment of patients with platinum-sensitive recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer (psOC)
