Clovis Oncology Receives Breakthrough Therapy Designation for Rubraca for Metastatic Castration Resistant Prostate Cancer

October 2, 2018
  • Rubraca previously received Breakthrough designation for the monotherapy treatment of certain advanced ovarian cancer patients
  • Rubraca is indicated as monotherapy for the treatment of adult patients with deleterious BRCA mutations (germline and/or somatic) associated epithelial ovarian, fallopian tube, or primary peritoneal cancer


Clovis Oncology, Inc. (NASDAQ: CLVS) announced on 10/2/18 that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for Rubraca (rucaparib) as a monotherapy treatment of adult patients with BRCA1/2-mutated mCRPC who have received at least one prior androgen receptor (AR)-directed therapy and taxane-based chemotherapy.

The FDA previously granted Breakthrough Therapy designation to Rubraca for the monotherapy treatment of certain advanced ovarian cancer patients and then in December 2016 approved Rubraca for the treatment of certain adult patients with deleterious BRCA mutation (germline and/or somatic) associated epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapies. The FDA subsequently approved Rubraca in a second indication, the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy, in April 2018.

This most recent Breakthrough Therapy designation was granted to Rubraca based on initial efficacy and safety results from TRITON2, the Phase 2 study of Rubraca in men with advanced prostate cancer with BRCA 1/2 mutations (germline or somatic) and deleterious mutations of other homologous recombination (HR) repair genes, in the metastatic castration-resistant setting.
Initial data from the TRITON2 clinical study, which served as the basis for BTD, will be presented for the first time at the 2018 European Society for Medical Oncology (ESMO) Congress taking place October 19-23, 2018, in Munich, Germany.

Rubraca is an oral, small molecule inhibitor of PARP1, PARP2 and PARP3 being developed in multiple tumor types, including ovarian, metastatic castration-resistant prostate, and bladder cancers, as monotherapy, and in combination with other anti-cancer agents. Exploratory studies in other tumor types are also underway. Clovis holds worldwide rights for Rubraca. Rubraca is an unlicensed medical product outside of the U.S. and Europe.

Rubraca is indicated as monotherapy for the treatment of adult patients with deleterious BRCA mutations (germline and/or somatic) associated epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapies and selected for therapy based on an FDA-approved companion diagnostic for Rubraca.
