Aadi NDA for Rare Sarcoma Drug
FDA has accepted for priority review an Aadi Bioscience NDA for its nanoparticle albumin-bound mTOR inhibitor Fyarro (sirolimus albumin-bound nanoparticles for injectable suspension) for treating advanced malignant PEComa, an ultra-rare sarcoma. The agency has set a user fee review action target date of 11/26.
The submission is based on data from the AMPECT registration trial evaluating Fyarro as a monotherapy in patients with advanced malignant PEComa. Data from the trial showed that the therapy had a 39% independently reviewed confirmed overall response rate in the patient population, according to the company. It says the mTOR inhibitor bound to human albumin has demonstrated greater mTOR target suppression and increased tumor growth inhibition over other mTOR inhibitors in preclinical models.
