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.
Merck KGaA has struck a collaboration and option-to-license deal with Nerviano Medical Sciences Srl centered around NMS-293, a next-generation PARP-1 inhibitor already in early clinical development for brain tumors. Merck is making a play for the poly (ADP-ribose) polymerase (PARP) inhibitor market, first opened up in December 2014 by Astrazeneca plc, when Lynparza (olaparib) was first approved in advanced ovarian cancer, going on to become a blockbuster through a partnership with Merck & Co Inc.
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.
Zai Lab Ltd. has shared positive top-line data from its phase III study for PARP inhibitor Zejula (niraparib) in the treatment of newly diagnosed ovarian cancer following a response to platinum-based chemotherapy. The study, called Prime, involved 384 advanced ovarian cancer patients in China and met its primary endpoint.

Illumina Inc. and Merck & Co. Inc. are partnering to commercialize tests identifying genetic mutations used in the assessment of homologous recombination deficiency.
Illumina Inc. and Merck & Co. Inc. are partnering to commercialize tests identifying genetic mutations used in the assessment of homologous recombination deficiency (HRD). Patients whose tumors are HRD-positive may be eligible for targeted chemotherapy treatment by a class of precision medicines called PARP inhibitors. The companies will develop tests utilizing Illumina's Trusight Oncology 500 assay for genomic profiling, which is designed to identify 523 known and emerging tumor biomarkers.
LONDON – Artios Ltd. has closed a $153 million series C, positioning it to intensify clinical development of its two lead programs, whilst applying its DNA damage response platform to exploit the full spectrum of vulnerabilities presented by inhibition of DNA damage repair enzymes.
Beigene Ltd.’s PARP inhibitor, pamiparib, won conditional approval from China’s National Medical Products Administration for treating patients with germline BRCA mutation-associated recurrent advanced ovarian, fallopian tube or primary peritoneal cancer who have been treated with two or more lines of chemotherapy.
