What this Trial Is About

Researchers are studying the safety, side effects, and effectiveness of LOXO-435 alone or combined with other standard cancer medicines in people with advanced solid tumors that have changes in the FGFR3 gene. This includes cancers of the urinary system like urothelial cancer. This open-label, multi-center phase 1 study aims to find the best dose and evaluate how well LOXO-435 works, with participation lasting up to 2.5 years or longer if the cancer does not worsen. The study has two main phases: Phase 1a, which focuses on dose escalation and optimization of LOXO-435 given orally, and Phase 1b, which expands the dose evaluation. LOXO-435 is studied as monotherapy or combined with pembrolizumab (an intravenous drug) with or without enfortumab vedotin (also given intravenously). Different groups receive these treatments to assess safety and early effectiveness in treating FGFR3-altered cancers. Participants will have regular assessments including tumor measurements, safety checks, and monitoring for side effects over the course of the study. Researchers will collect data on treatment response, progression, survival, physical function, and bladder-related symptoms. The study also monitors drug levels in the body and tracks adverse events for up to about 30 months, ensuring close follow-up throughout the trial.

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

Treatment

Duration - Up to approximately 30 months or 2.5 years

Participants receive LOXO-435 as an oral drug, alone or in combination with pembrolizumab and/or enfortumab vedotin administered intravenously, to assess safety, tolerability, and preliminary anti-tumor activity.

Visits occur regularly during treatment cycles, including initial dose escalation and optimization phases followed by dose expansion cohorts.
