Nuvectis Pharma announces preliminary data from NXP800 Phase 1b trial

Nuvectis Pharma announced preliminary data from the ongoing Phase 1b clinical trial of NXP800 in patients with platinum resistant ARID1a-mutated ovarian cancer, a deadly disease of unmet medical need. The NXP800 development program in this disease was granted Fast Track Designation by the U.S. Food and Drug Administration. The Phase 1b clinical trial is being conducted in top clinical centers in the United States and the United Kingdom. Encouraging preliminary efficacy data was observed and includes data from the first four patients enrolled in the study, two treated with 75 mg/day and two treated with 50 mg/day. All patients failed at least two prior lines of systemic chemotherapy, including at least one prior platinum-based chemotherapy regimen. Three of the patients also failed prior treatment with bevacizumab. Efficacy was evaluated in three of the four patients. One patient treated with 75 mg/day achieved a PR, unconfirmed, that also included a CR of her non-target lymph node disease. Both patients treated with 50 mg/day achieved SD and the fourth patient was not evaluated for efficacy. Three of these four patients experienced an adverse event of thrombocytopenia that was Grade 4 in intensity, these events were transient in nature with no concurrent bleeding events reported. Following these events, as mentioned above, a management procedure for the monitoring of platelets and dose adjustments, as necessary, has been implemented with the goal of minimizing dosing interruptions and increasing patient retention. No other greater than or equal to Grade 3 hematological toxicities were reported. In addition, gastrointestinal adverse events were reported in all four patients, all Grade 1-2.
