A Phase 1 Study of CTIM-76 in Patients With Recurring Ovarian Cancer and Other Advanced Solid Tumors

Summary

This is a Phase 1a/1b, open-label, dose escalation and expansion study to evaluate the safety and efficacy of CTIM-76 (study drug), a CLDN6-directed T cell-engaging bispecific antibody , in participants with platinum-refractory/resistant ovarian cancer (PRROC) and other advanced CLDN6-positive solid tumors (i.e., testicular and endometrial).

Detailed Description

The phase 1a dose escalation portion of the trial will enroll participants with PRROC, testicular, or endometrial cancer into one of approximately 9 dose escalation cohorts to assess safety, tolerability and to determine the recommended dose for expansion (RDE). CTIM-76 is to be administered once according to the dose and schedule of the assigned cohort. Participants will be dosed until documentation of disease progression, unacceptable toxicity, or participant/physician decision. The phase 1b dose expansion phase will first evaluate CTIM-76 in PRROC at minimum, 2 dose levels and/or dosing schedules will be evaluated (n=20 response evaluable participants in each cohort) in the dose expansion phase of the trial. . This is to enable dose- and exposure-response analyses. The expansion doses/dosing schedules for Phase 1b will be determined by Sponsor in conjunction with Safety Review Committee (SRC) based upon all available safety, pharmacokinetic (PK), pharmacodynamic (PD), biomarker and preliminary efficacy data from Phase 1a. The selection of the RP2D will be based on the totality of data from Phase 1b.
