Study Summary

This trial is testing a new cancer treatment that combines VESANOID with pembrolizumab.

Who is the study for?
Adults with advanced melanoma (unresectable Stage III or IV) who plan to undergo pembrolizumab treatment, can consent, follow trial procedures for its duration, and use contraception. Excluded are those with recent cancer treatments, active infections, pregnancy/breastfeeding intentions during the trial, prior anti-PD-1/L1/L2 therapy, immunodeficiency or suppressive therapy within 7 days of starting the trial.Check my eligibility
What is being tested?
This Phase I/Ib open-label study tests a combination of VESANOID (All-Trans Retinoic Acid) and pembrolizumab in treating advanced melanoma. It aims to understand how well these drugs work together and their safety profile in patients.See study design
What are the potential side effects?
Potential side effects include immune-related reactions affecting organs like lungs or liver (pneumonitis/hepatitis), infusion reactions from pembrolizumab administration, fatigue, skin issues due to retinoids such as dryness or rash; exact side effects will be monitored throughout the study.
