PL3397-A-U401: A Long-term Study Evaluating Hepatotoxicity Associated With TURALIO™ (Pexidartinib) Treatment
Why are we doing this research?
This FDA post-marketing requirement study will evaluate the long-term risk of hepatic failure with TURALIO™ (pexidartinib) and the mechanism of liver injury based upon liver biopsy information among patients who received or are receiving TURALIO™ (pexidartinib) for symptomatic tenosynovial giant cell tumor (TGCT) associated with severe morbidity or functional limitations and not amenable to improvement with surgery, and who experience hepatotoxicity. A liver biopsy will be collected from enrolled patients for central laboratory analysis of macrophage and immune cell profiles to investigate possible mechanisms of the hepatotoxicity. Additionally, 4 blood samples will be collected to evaluate liver function, other relevant safety tests, peripheral immune cells, and for pharmacogenomic testing. Enrolled patients will be followed at least yearly for 10 years to assess long-term risk of hepatic failure.
