NPX800

Fort Lee, NJ, May 15, 2023 (GLOBE NEWSWIRE) -- Nuvectis Pharma, Inc. (NASDAQ: NVCT) ("Nuvectis" or the "Company"), a clinical-stage biopharmaceutical company focused on the development of innovative precision medicines for the treatment of serious conditions of unmet medical need in oncology, today announced that the U.S. Food and Drug Administration (“FDA”) cleared the Company's Investigational New Drug Application (“IND”) for NXP900, which includes the Phase 1 clinical trial protocol. “The IND clearance by the FDA is a significant milestone for the NXP900 development program and for our overall corporate strategy, further demonstrating our ability to execute our business plan,” said Ron Bentsur, Chairman and Chief Executive Officer of Nuvectis. Mr. Bentsur continued, “Nuvectis now has two precision oncology, clinical-stage drug candidates, each with several potential opportunities in cancers that represent serious conditions of unmet medical need. We believe that NXP900 presents a unique opportunity due to its differentiated mechanism of action and pharmacologic attributes, and we are excited to start the clinical program to unlock its therapeutic potential.” About NXP900 Nuvectis licensed exclusive world-wide rights to NXP900, a novel inhibitor of the SRC family of kinases (“SFKs”) with low nanomolar potency against YES1 and SRC, from the University of Edinburgh in Scotland. Over activation of SFKs occurs frequently in tumor tissues and they are central mediators in multiple oncogenic signaling pathways. YES1, a key member of the SFKs, enhances the phosphorylation, nuclear localization and oncogenic activity of YAP1, a key Hippo pathway effector. In preclinical studies, NXP900 demonstrated robust single agent antitumor activity in several in vivo xenograft models, including in squamous cell cancers such as cervical, head and neck and esophageal carcinomas in which Hippo pathway mutations and copy number abnormalities are prevalent. In addition, NXP900 in combination with osimertinib (the active ingredient in TAGRISSO®) in vitro and with enzalutamide (the active ingredient in Xtandi®) in vivo demonstrated the potential ability to reverse acquired resistance to these drugs in non-small cell lung cancer and metastatic castration-resistant prostate cancer, respectively. About Nuvectis Nuvectis Pharma, Inc. is a clinical-stage 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 drug candidates, NXP800 and NXP900. NXP800 is a clinical stage, oral small molecule currently in a Phase 1b study. NXP800 was granted Fast Track Designation by the FDA for the treatment of platinum-resistant, ARID1a-mutated, ovarian carcinoma. NXP900 is a novel inhibitor of SFKs with low nanomolar potency against YES1 and SRC. The IND for NXP900 has been cleared by the FDA and the Phase 1a study is expected to commence in the coming months. For more information, please visit .

Phase 1b study builds on highly consistent preclinical and Phase 1a data Fort Lee, NJ, USA I April 10, 2023 I Nuvectis Pharma, Inc. (NASDAQ: NVCT) ("Nuvectis" or the "Company"), a clinical-stage biopharmaceutical company focused on the development of innovative precision medicines for the treatment of serious conditions of unmet medical need in oncology, today announced the initiation of the Phase 1b study for NXP800 in platinum-resistant, ARID1a-mutated ovarian carcinoma. The Phase 1b study is a multicenter, single-agent, open-label clinical trial of NXP800 in patients with platinum-resistant, ARID1a-mutated ovarian cancer, a tumor type that is comprised almost exclusively of ovarian clear-cell carcinoma (“OCCC”) and ovarian endometrioid carcinoma (“OEC”). The study will examine the safety, tolerability and preliminary efficacy of NXP800 in this target patient population. The study will enroll two cohorts of up to approximately 25 patients each and will evaluate two dosing regimens, 50 mg and 75 mg, administered once daily, selected based on data from the Phase 1a dose escalation study in patients with various types of advanced solid tumors. The study will be conducted in 25-30 sites in the United States (“U.S.”), United Kingdom (“UK”) and Europe in collaboration with the European Network of Gynaecological Oncological Trial Groups and the GOG Foundation, Inc., recognized as the world's premier gynecology oncology clinical trials consortia. The NXP800 development program in platinum-resistant, ARID1a-mutated ovarian cancer was granted Fast Track Designation by the U.S. Food and Drug Administration (“FDA”). “We are excited to announce the initiation of the Phase 1b study in which NXP800 will be tested, for the first time, in patients with a target disease,” said Ron Bentsur, Chairman and Chief Executive Officer of Nuvectis. “The robust preclinical anti-tumor activity of NXP800, coupled with the data from the Phase 1a dose escalation study, led to the design of the Phase 1b study, including the definition of the patient population and selection of doses and dosing schedules.” Mr. Bentsur concluded, “Based on the totality of the data generated to date, we believe that NXP800 has the potential to become an effective treatment for patients with platinum-resistant, ARID1a-mutated ovarian carcinoma, as well as additional target tumor types, which we plan to also investigate in the near term." About NXP800 NXP800 is an oral, small molecule inhibitor of the HSF1 pathway. NXP800 has demonstrated robust anti-tumor activity in xenograft models of ARID1a-mutated ovarian carcinoma and other disease models. The NXP800 development program in platinum-resistant, ARID1a-mutated ovarian carcinoma was granted Fast Track Designation by the U.S. FDA. Nuvectis licensed exclusive world-wide rights to NXP800 from the Institute of Cancer Research in London, UK. Phase 1a Data Highlights About Platinum-Resistant, ARID1a-Mutated Ovarian Carcinoma ARID1a-mutated ovarian carcinoma is comprised almost exclusively of two histologies, OCCC and OEC, each representing about 10% of the overall ovarian cancer cases in the U.S. with an annual incidence of approximately 2,200 patients per histology. Platinum resistant ovarian carcinoma is recognized as a serious condition of unmet medical need, given the lack of effective treatments and the poor patient prognosis in this setting. It is estimated that approximately 66% of patients with OCCC and 40% of patients with OEC have the ARID1a mutation, supporting the potential opportunity for the use of NXP800 as a new therapeutic option.
