Rucaparib MAA for the Ovarian Cancer Treatment Indication Referred by CHMP to Scientific Advisory Group on Oncology for Review Expected in February 2018
Clovis Oncology, Inc. (NASDAQ: CLVS) announced today that the European Union’s (EU) European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP) has requested that the Scientific Advisory Group (SAG) on Oncology provide an opinion on aspects of the ongoing Marketing Authorization Application (MAA) relating to a potential conditional approval for rucaparib. The exact date for the SAG meeting has not yet been set but we expect it to take place in early February 2018.
The SAG on Oncology is convened at the request of the EMA to provide independent recommendations on scientific or technical matters related to pediatric and adult clinical oncology and hematology, or on any other scientific issue relevant to the work of the Agency that relates to this area.
“We continue to have as our priority the submission and potential approval for the maintenance treatment indication in advanced ovarian cancer in the EU,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “We anticipate that initiating the process to submit a new MAA for maintenance next month is the quickest path to provide the potential benefit of rucaparib to more women in the EU with advanced disease. Of course, if we receive an approval for the treatment indication in the second quarter, and we file a variation to the treatment MAA, we anticipate the potential maintenance approval would be swifter.”
The CHMP application for the treatment indication currently under review was submitted during the fourth quarter of 2016 and was based on objective response rate and duration of response results from two multicenter, single-arm, open-label clinical trials, Study 10 and ARIEL2, in women with advanced BRCA-mutant ovarian cancer who had progressed after two or more prior chemotherapies. All 106 patients received rucaparib orally 600 mg twice daily as monotherapy until disease progression or unacceptable toxicity. Objective response rate (ORR) and duration of response (DOR) were assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. The most common Grade 3/4 adverse event was anemia.
Both the variation to the MAA or a new MAA submission will be based on data from the phase 3 ARIEL3 clinical trial, which found that rucaparib significantly improved progression-free survival in all ovarian cancer patient populations studied. ARIEL3 is a double-blind, placebo-controlled trial of rucaparib that enrolled 564 women with platinum-sensitive, high-grade ovarian, fallopian tube, or primary peritoneal cancer. The primary efficacy analysis evaluated three prospectively defined molecular sub-groups in a step-down manner: 1) BRCA mutant; 2) HRD-positive; and finally, 3) the intent-to-treat population, or all patients treated in ARIEL3. Both the variation to the MAA or the new MAA filing will be directed at the broader intent-to-treat or “all comers” population.
Clovis announced positive topline results from the ARIEL3 clinical trial in June 2017. The comprehensive dataset from the trial was presented at the 2017 European Society for Medical Oncology (ESMO) Annual Conference in Madrid, Spain,i and subsequently published in The Lancet .ii
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. In December 2017, the US Food and Drug Administration (FDA) accepted the Company’s supplemental New Drug Application (sNDA) for rucaparib for a second-line or later maintenance treatment indication in ovarian cancer based on the ARIEL3 data. The FDA granted Priority Review status to the application with a Prescription Drug User Fee Act (PDUFA) date of April 6, 2018. In December 2017, the CHMP referred the rucaparib MAA for the ovarian cancer treatment indication to the SAG on Oncology for review. The SAG meeting to discuss the rucaparib MAA is anticipated in February 2018. Studies open for enrollment or under consideration include ovarian, prostate, breast, gastroesophageal, pancreatic, lung and bladder cancers. Clovis holds worldwide rights for rucaparib.
