The U.S. FDA’s Oncologic Drugs Advisory Committee has recommended by a wide majority that the PARP inhibitor Lynparza (olaparib) in a combination therapy for treating prostate cancer should be restricted to only patients whose tumors have a BRCA mutation.
The U.S. FDA’s Oncologic Drugs Advisory Committee meets April 28 to discuss the future of Astrazeneca plc and Merck & Co. Inc.’s supplemental NDA for Lynparza (olaparib) for an expanded label to treat prostate cancer. It has a few bones to pick. The FDA said it is concerned that the efficacy and safety have not been demonstrated outside of the small population of patients with tumor BRCA mutations and that the addition of olaparib to abiraterone may cause harm in patients who are definitively negative for tumor BRCA mutations.
GSK plc said it will restrict the second-line maintenance indication for ovarian cancer drug Zejula (niraparib) to only patients with deleterious or suspected germline BRCA mutations, at the request of the FDA, in a sign that U.S. regulators aren’t going to relax scrutiny on PARP inhibitors any time soon.

A Mayo Clinic study demonstrated how the deficiency of the enzyme CDK12 or its regulation by cyclin K causes the expression of mutations related to resistance to endocrine therapy in prostate cancer. Prostate tumors with CDK12 deficiency are more aggressive, recurrent, produce metastases and are associated with castration-resistant prostate cancer (CRPC). CDK12 deficiency impairs DNA repair and increases genomic instability, causing an effect known as homologous recombination deficiency or BRCAness.
Nodus Oncology Ltd. is set to explore new avenues of DNA damage response by targeting the chromosome next-door neighbors of tumor suppressor genes that are damaged when tumor suppressor genes are inactivated via homozygous deletion. These collaterally deleted ‘passenger genes’ play diverse functions in cell homeostasis and so present a number of molecularly targeted vulnerabilities that can provide a route to destroying cells which carry a tumor suppressor gene.
Clovis Oncology Inc. is trying to claw its way into ovarian cancer relevance against vastly larger competitors Astrazeneca plc and Glaxosmithkline plc with positive top-line phase III data from its study of PARP inhibitor Rubraca (rucaparib). The study’s monotherapy arm of Rubraca as a first-line maintenance treatment of ovarian cancer hit the primary endpoint of significantly improved investigator-assessed progression-free survival (PFS) compared to placebo. The median PFS was 20.2 months for Rubraca compared to 9.2 months for placebo in the intent-to-treat group.
Myriad Genetics Inc. is launching a new suite of genetic tests designed for personalizing chemotherapy treatment. The Precise oncology offering includes Myriad’s precise tumor molecular profile test and two companion diagnostic tests, Mychoice CDx and Bracanalysis CDx. The company said the combination of germline, somatic and companion testing aims to maximize information for oncologists as they assign individual treatment plans. Results from each test are gathered as a single report accessed on an online portal.
Astrazeneca plc and Merck & Co. Inc. have data for a new indication for their blockbuster PARP inhibitor class drug Lynparza (olaparib) in advanced prostate cancer in combination with standard abiraterone therapy. The companies said the Propel phase III study testing Lynparza in combination with abiraterone showed a statistically significant and clinically meaningful improvement in radiographic progression-free survival in first-line metastatic castration-resistant prostate cancer vs. standard abiraterone care.
The American Society for Clinical Oncology’s (ASCO) virtual annual meeting began June 3 with the release of late-breaking abstracts, including LBA-1 on “Olympia: A phase 3, multicenter, randomized, placebo-controlled trial of adjuvant olaparib after (neo)adjuvant chemotherapy in patients with germline BRCA1 and BRCA2 mutations and high risk HER2-negative primary breast cancer.”
