Fort Lee, NJ, Dec. 17, 2025 (GLOBE NEWSWIRE) -- Nuvectis Pharma, Inc. (NASDAQ: NVCT), 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 of NXP900 in combination with osimertinib in patients with EGFRmut+ NSCLC. NXP900, an oral small molecule drug candidate, is a potent inhibitor of the SRC and YES1kinases. The brand name for Osimertinib is Tagrisso®, marketed by Astra Zeneca. Tagrisso, a 3rd generation EGFR inhibitor is broadly used in patients with NSCLCmut+ as single agent or in combination with chemotherapy as a first or later line of therapy. It has been described in the scientific literature that activation of the SRC/YES1 pathway drives resistance to EGFR inhibitor therapy in EGFRmut+ NSCLC.
NXP900 Phase 1b Clinical Program
The Phase 1b program was initiated with the NXP900 single agent (monotherapy) study following the successful completion of a Phase 1a dose escalation study in patients with advanced solid tumors and a clinical drug-drug interaction study in healthy volunteers.
The ongoing single agent study evaluates the safety and clinical activity of NXP900 in patients with specific genetic alterations selected based on their characteristics as either direct or dependent targets of NXP900, and the tumor types were selected based on the prevalence of the relevant genetic alterations and supporting scientific data. Today marks the commencement of the first combination study of NXP900 as part of the Phase 1b program.
Phase 1b of NXP900 in Combination with Osimertinib in Patients with EGFRmut+ NSCLC
Eligible patients for this study include those with unresectable, metastatic or locally advanced EGFRmut+ NSCLC who have been previously treated with, and had a response to, osimertinib in the first or second line setting as a single agent or in combination with chemotherapy. Patients whose tumors harbor mutations in the EGFR domain that are known to cause resistance to osimertinib, or who have other known oncogenic drivers other than EGFR mutation are not eligible.
Ron Bentsur, Chairman and Chief Executive Officer of Nuvectis commented, "We are pleased to announce the initiation of the NXP900 plus osimertinib combination study, as we continue to advance the NXP900 clinical program and unlock NXP900’s promising therapeutic potential.” Mr. Bentsur added, “The clinical benefit and improved outcomes afforded by osimertinib to patients with EGFRmut+ NSCLC are well known, and we believe, based on extensive medical and scientific literature and proof of concept experiments done by us and others, that a combination with NXP900 has the potential to extend these benefits in patients who acquired resistance to osimertinib, using an all oral combination of osimertinib and NXP900.” Mr. Bentsur concluded, “We expect 2026 to be an exciting year with multiple data readouts from both the single agent and combination studies, and we look forward to providing updates from the program throughout the year."
About Nuvectis Pharma, Inc.
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’s assets include two clinical-stage drug candidates, NXP900 and NXP800. NXP900 is an oral small molecule inhibitor of the SRC Family of Kinases (SFK), including SRC and YES1. Its unique mechanism of action enables inhibition of both the catalytic and scaffolding functions of the SRC kinase, providing comprehensive shutdown of the signaling pathway. NXP900 has completed a Phase 1a dose escalation study and the Phase 1b program has been initiated. NXP800 is an oral small molecule GCN2 activator that has demonstrated anti-cancer activity in recurrent, platinum-resistant, ARID1a-mutated ovarian cancer, and may be explored in the future in other cancer types.
