A Phase 1 Study of PLN-101095 in Adults With Advanced or Metastatic Solid Tumors

Sponsored by Pliant Therapeutics, Inc.

About this study

This is a Phase 1a/1b, dose-escalation/expansion, consecutive-cohort, open-label study to evaluate the safety, tolerability, PK, PD, and preliminary evidence of antitumor activity of PLN-101095 in combination with pembrolizumab (the study treatment regimen) in adult participants with advanced or metastatic solid tumors for which pembrolizumab is indicated but have documented disease progression (refractory \[primary resistance\]) or relapsed \[secondary resistance\]) after at least 3 months from the start of treatment with pembrolizumab. The study will consist of 2 main parts: * Part 1: Consecutive dose-escalation cohorts using a Bayesian optimal interval (BOIN) dose escalation design with accelerated titration * Part 2: Dose-expansion cohorts using Simon's 2-stage design

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
