Clovis Oncology Inc. (NASDAQ: CLVS) is a biopharmaceutical company focused on acquiring, developing and commercializing innovative anti-cancer agents in the U.S., Europe and additional international markets. The company’s shares jumped about 47% after the company announced topline data from the confirmatory phase 3 ARIEL3 trial of rucaparib, which successfully achieved the primary endpoint of improved progression-free survival (PFS) by investigator review in each of the three populations studied. The stock increased in value by almost 100% year to date.

The company also provided data showing that the PFS was also improved in the rucaparib group compared with placebo by blinded independent central review (BICR), a key secondary endpoint.

The next step for Clovis is to submit a supplemental New Drug Application (sNDA) within the next four months for a second-line and later maintenance treatment indication for all women with platinum-sensitive ovarian cancer who have responded to their most recent platinum therapy.

 “We are very pleased with these positive ARIEL3 topline results that strongly demonstrate the potential of rucaparib to help women with platinum-sensitive, advanced ovarian cancer,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “These results reinforce the potentially foundational role of rucaparib in the management of advanced ovarian cancer, as demonstrated by both investigator review and the blinded independent central review. Most importantly, we are grateful to the patients, caregivers and investigators who participated in this study. We look forward to sharing these data in greater detail at a medical meeting later this year and submitting our sNDA as rapidly as possible, with the ultimate goal of making rucaparib available to more women battling ovarian cancer.”
