Etiglimab/Nivolumab combination shows promise in solid tumors
Source: www.targetedonc.com Author: Sara Karlovitch The combination of etigilimab, an anti-TIGIT antibody, in combination with nivolumab (Opdivio) has demonstrated anti-tumor efficacy and acceptable safety data in patients with solid tumors, according to a press release on the interim results of the phase 1b/2 ACTIVATE trial by Mereo BioPharma Group plc. The phase 1b/2 study (NCT04761198) has a target enrollment of 125 participants and an estimated study completion date of June 2023. The primary end point is objective response rate. During the study, patients will receive an infusion of etigilimab every 2 weeks and an infusion of nivolumab every 2 weeks. Cohorts include squamous cell carcinoma of the head and neck, cervical cancer on or after chemotherapy, gastric or gastroesophageal junction adenocarcinoma, endometrial carcinoma, tumor burden high and microsatellite stable solid tumors, rare disease with high TIGIT expression, ovarian cancer, and endometrial carcinoma post standard of care therapy. At the time of data cutoff, 22 patients were included in the safety analysis. Twenty patients were evaluable with a minimum of at least one scan and 15 were included in the efficacy analysis. The analysis found that 1 patient in the cervical cancer cohort had a complete response. In the ovarian cancer cohort, 1 patient had a partial response. Four patients with stable disease was seen in ovarian cancer, cervical cancer, and uveal melanoma. Additionally, the ovarian cancer cohort has crossed futility for expansion into the second stage of the study. The combination was found to be well tolerated, and no new [...]
