Nuvectis Pharma Announces Orphan Drug Designation for the Treatment of ARID1a-Deficient Ovarian, Fallopian Tube & Primary Peritoneal Cancers

Nuvectis Pharma, Inc. recently announced that NXP800 was granted Orphan Drug Designation by the US FDA for the treatment of AT-rich interactive domain-containing protein 1a (ARID1a) ARID1a-deficient ovarian, fallopian tube, and primary peritoneal cancers.

Ron Bentsur, Chairman and Chief Executive Officer of Nuvectis, said “We are very pleased to have received this designation from the FDA for NXP800. The prevalence of ovarian cancer, which is comprised of ovarian, fallopian tube and primary peritoneal cancers, exceeds the 200,000 patient threshold below which drugs may be eligible to receive Orphan Drug Designation in the US and in ovarian cancer it has been uncommon to receive this designation for the treatment of a subset of the disease. We therefore believe that this Orphan Drug Designation granted by the FDA for NXP800 for the treatment of a subset of ovarian cancer, specifically for patients with an ARID1a deficiency, provides further validation for NXP800’s mechanism of action and the target patient population in our ongoing Phase 1b clinical trial in patients with platinum resistant, ARID1a-mutated ovarian cancer. We expect to provide a data update from this study this coming fall.”

Orphan Drug Designation is granted by the FDA to drugs or biologics intended to treat a rare disease or condition, defined as one that affects fewer than 200,000 people in the US. Orphan Drug Designation provides certain financial incentives to support clinical development, and the potential for up to seven years of marketing exclusivity for the product for the designated orphan indication in the US if the product is approved for its designated indication.

Nuvectis Pharma, Inc. is a biopharmaceutical company focused on the development of innovative precision medicines for the treatment of serious conditions of unmet medical need in oncology. The company is currently developing two clinical-stage drug candidates, NXP800 and NXP900. NXP800 is an oral small molecule GCN2 activator currently in a Phase 1b clinical trial for the treatment for platinum resistant, ARID1a-mutated ovarian carcinoma and in an Investigator-sponsored clinical trial for the treatment of cholangiocarcinoma. The US FDA granted Fast Track Designation to the NXP800 development program in platinum resistant, ARID1a-mutated ovarian carcinoma, and Orphan Drug Designation for the treatment of cholangiocarcinoma and ARID1a-deficient ovarian, fallopian tube, and primary peritoneal cancers. NXP900 is an oral small molecule inhibitor of the SRC Family of Kinases (SFK), including SRC and YES1. NXP900 has a unique mechanism of action in that it inhibits both the catalytic and scaffolding functions of the SRC kinase thereby providing complete shutdown of the signaling pathway. NXP900 is currently in a Phase 1a dose escalation study.
