Genentech Release: Phase III Study Showed Avastin-Based Regimen Helped Women with Advanced Ovarian Cancer Live Longer Without Their Disease Worsening

CHICAGO--(BUSINESS WIRE)--Genentech, Inc., a wholly owned member of the Roche Group, (SIX: RO, ROG; OTCQX: RHHBY) today announced results from a Phase III study of Avastin® (bevacizumab) that showed women with previously untreated advanced ovarian cancer who received Avastin in combination with chemotherapy, followed by the continuation of Avastin alone, had a 39 percent improvement in the likelihood of living longer without the disease worsening (progression-free survival or PFS) compared to chemotherapy alone. An assessment of safety noted adverse events consistent with those observed in pivotal trials of Avastin. The study (known as GOG 0218), was conducted by a network of researchers led by the Gynecologic Oncology Group (GOG).
