FORAGER-1: A Study of LOXO-435 (LY3866288) in Participants With Cancer With a Change in a Gene Called FGFR3

Официальное название

FORAGER-1: A Phase 1, Open-Label, Multicenter Study of LOXO-435 (LY3866288) in Locally Advanced or Metastatic Solid Tumors Including Urothelial Cancer With FGFR3 Alterations

Обзор

The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435 by itself or when it is combined with other standard medicines that treat cancer. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.

Подробное описание

This is an open-label, multi-center, phase 1 study in participants with FGFR3-altered advanced solid tumor malignancy including metastatic urothelial cancer (UC). The study will be conducted in 2 phases: Phase 1a dose escalation (Cohort A1) and dose optimization (Cohort A2) and Phase 1b dose expansion. Phase 1a will assess safety, tolerability, and pharmacokinetics of LOXO-435 to determine the optimal dose for further expansion.

Phase 1b will include 6 dose expansion cohorts to evaluate the efficacy and safety of LOXO-435 as monotherapy or in combinations with pembrolizumab with or without enfortumab vedotin.
