About the PRECISION 1 Trial
The PRECISION 1 Trial is a multi-center, open-label, tumor-agnostic pivotal study, of nab-sirolimus designed as a basket trial that will evaluate approximately 120 adult and adolescent patients with solid tumors harboring pathogenic inactivating alterations in TSC1 or TSC2 genes. The trial will have two independent arms of 60 patients each to separately evaluate patients with either TSC1 or TSC2 inactivating alterations. Aadi has received Fast Track designation to evaluate nab-sirolimus in this indication from the FDA. The trial opened for enrollment in February 2022.
