Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Experimental: Phase 1b: Cohort B2 LOXO-435 Monotherapy Dose Expansion - LOXO-435 administered orally to participants with FGFR3-altered advanced urothelial carcinoma who have not received a prior FGFR inhibitor.

Experimental: Phase 1b: Cohort B3 LOXO-435 Plus Pembrolizumab - LOXO-435 administered orally in combination with pembrolizumab administered intravenously (IV) to participants with FGFR3-altered advanced urothelial carcinoma who have not received a prior FGFR inhibitor.

Summary
Brief summary
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435. 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.
