Aadi Bioscience won approval for Fyarro, the albumin-bound sirolimus that treats the rare sarcoma PEComa, then sold it and renamed itself Whitehawk Therapeutics to develop antibody-drug conjugates.
Aadi Bioscience developed nab-sirolimus (Fyarro, ABI-009), an mTOR inhibitor bound to albumin nanoparticles for better tumour delivery. The FDA approved it in November 2021 for malignant perivascular epithelioid cell tumour, the first drug for that sarcoma; the PRECISION 1 trial tested it in tumours with TSC1 or TSC2 alterations. In 2025 Aadi sold Fyarro to Kaken Pharmaceutical, in-licensed three antibody-drug conjugates from WuXi Biologics and Hangzhou DAC, and became Whitehawk Therapeutics.
Fyarro is an infusion of the transplant drug sirolimus packaged in albumin particles. It is the first approved treatment for malignant PEComa, a rare soft-tissue tumour driven by loss of the TSC genes.
