BOULDER, Colo.--(BUSINESS WIRE)--

Clovis Oncology, Inc. (NASDAQ: CLVS) today announced that abstracts highlighting progress in the rucaparib clinical development program will be presented at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting taking place June 2-6 in Chicago.

Four abstracts highlighting ongoing rucaparib clinical trials will showcase some of the multiple cancer types in which the compound is being studied, including germline and somatic BRCA-mutated, relapsed, high-grade ovarian cancer; metastatic castration-resistant prostate cancer associated with homologous recombination deficiency; and HER2 negative metastatic breast cancer.

“The abstracts being presented at ASCO 2017 highlight the depth of our clinical program exploring the potential of rucaparib as a precision medicine therapeutic for multiple cancer types,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “The oncology community has taken great interest in PARP inhibitors and the role of these novel therapeutics within the cancer treatment paradigm. We are pleased to describe these current clinical studies evaluating rucaparib in various solid tumor settings at this prestigious meeting, and importantly, we look forward to announcing the top-line results from ARIEL3 in the ovarian cancer maintenance treatment setting by the end of June.”

Rucaparib is Clovis Oncology’s oral, potent, small-molecule inhibitor of PARP1, PARP2 and PARP3. In December 2016, the FDA approved rucaparib (Rubraca^®) tablets as monotherapy for women with advanced ovarian cancer who have been treated with two or more chemotherapies and whose tumors have a deleterious BRCA mutation (germline and/or somatic) as identified by an FDA-approved companion diagnostic test.

The ARIEL3 pivotal study of rucaparib is a randomized, double-blind study comparing the effects of rucaparib against placebo to evaluate whether rucaparib given as a maintenance treatment to platinum-sensitive ovarian cancer patients can extend the period of time for which the disease is controlled after a response to platinum-based chemotherapy. Top-line results from ARIEL3 are anticipated by the end of June, and the Company plans to provide a more comprehensive presentation of the ARIEL3 results in a scientific session at a medical meeting later this year. Pending positive data, the Company intends to submit a supplemental New Drug Application (NDA) for a second line or later maintenance treatment indication within approximately four months of the database lock.

The three trials-in-progress abstracts accepted for presentation at the 2017 ASCO Annual Meeting comprise:

About Rucaparib

Rucaparib is an oral, small molecule inhibitor of PARP1, PARP2 and PARP3 being developed in ovarian cancer as well as several additional solid tumor indications. The MAA submission in Europe for an ovarian cancer treatment indication was submitted and accepted during the fourth quarter of 2016. Additionally, rucaparib is being developed as maintenance treatment for ovarian cancer in the ARIEL3 trial for patients with tumors with BRCA mutations and other DNA repair deficiencies beyond BRCA, as well as biomarker negative patients. Topline results from ARIEL3 are expected by late June, which, pending positive data, is expected to be followed by the submission of a sNDA for a second line or later maintenance treatment indication. Rucaparib is also being developed in patients with mutant BRCA tumors and other DNA repair deficiencies beyond BRCA – commonly referred to as homologous recombination deficiencies, or HRD. Studies open for enrollment or under consideration include prostate, breast, pancreatic, gastroesophageal, bladder and lung cancers. Clovis holds worldwide rights for rucaparib.
