Aadi Bioscience Presents PRECISION 1 Trial in Progress Poster and AMPECT Trial Final Analysis at the Connective Tissue Oncology Society (CTOS) 2022 Annual Meeting


Trial-in-progress poster showcases clinical trial design for PRECISION 1 and two additional posters demonstrate favorable durability of response and long-term safety of nab-sirolimus in the completed AMPECT study

LOS ANGELES, Nov. 17, 2022 /PRNewswire/ -- Aadi Bioscience, Inc. (NASDAQ: AADI), a commercial-stage biopharmaceutical company focused on developing and commercializing precision therapies for genetically-defined cancers with alterations in mTOR pathway genes, today presented three posters on completed and ongoing clinical trials for nab-sirolimus at the Connective Tissue Oncology Society (CTOS) 2022 Annual Meeting, taking place November 16-19, 2022 in Vancouver, Canada. nab-sirolimus (FYARRO®) is a novel mTOR inhibitor that leverages albumin-bound nanoparticle technology and is approved for the treatment of locally advanced unresectable or metastatic malignant perivascular epithelioid cell tumor (PEComa).

"We are thrilled to share more information from our AMPECT and PRECISION 1 trials with the leading sarcoma specialists from around the globe at CTOS 2022," said Loretta Itri, M.D., Chief Medical Officer of Aadi Bioscience. "The trial-in-progress poster presents the design of our PRECISION 1 trial, while our two additional posters provide long-term analysis from our AMPECT trial that demonstrates nab-sirolimus' durability of response and long-term safety. We want to thank the CTOS organizers for the opportunity to showcase Aadi's clinical success and the patients who participated in these studies."

Details of the poster presentations are below:

Title: "Phase 2, Multicenter, Open-Label Basket Trial of nab-Sirolimus for Patients with Malignant Solid Tumors Harboring Pathogenic Inactivating Alterations in TSC1 or TSC2 Genes (PRECISION 1)"
Date/Time: Thursday, November 17, 2022

Aadi and its collaborators present a trial-in-progress poster for PRECISION 1, a registrational-directed trial now recruiting for patients with solid tumors driven by TSC1/TSC2 alterations, an underserved patient population with no targeted therapeutic options.

Title: "Study-end Analysis from AMPECT, an Open-Label, Phase 2 Registration Trial of Patients with Advanced Malignant PEComa Treated with nab-Sirolimus, Showing Durability of Responses and Long-Term Safety"
Date/Time: Thursday, November 17, 2022

Aadi and its collaborators present final 3-year follow up data from the AMPECT Phase 2 study. The AMPECT study met its primary endpoint, showing a median Duration of Response (DoR) of over 3 years. In addition, median Overall Survival (OS) was updated to 53.1 months. Overall Response Rate (ORR), Disease Control Rate (DCR), and Progression Free Survival (PFS) were consistent with prior analysis of nab-sirolimus in AMPECT.

Title: "Management of Adverse Events in the AMPECT Trial of nab-Sirolimus for the Treatment of Advanced Malignant Perivascular Epithelioid Cell Neoplasm (PEComa)
Date/Time: Thursday, November 17, 2022

Aadi and its collaborators present data on the adverse event (AE) management in the AMPECT trial over three years after the primary analysis was presented.  nab-Sirolimus was generally well-tolerated, and the majority of the AEs due to nab-sirolimus treatment in the AMPECT trial were manageable. Importantly, dose reductions for AE management did not appear to compromise efficacy in patients who responded to therapy.

About Aadi Bioscience

Aadi is a commercial-stage biopharmaceutical company focused on precision therapies for genetically defined cancers. Aadi's primary goal is to bring transformational therapies to cancer patients with mTOR pathway driver alterations where other mTOR inhibitors have not or cannot be effectively exploited due to problems of pharmacology, effective drug delivery, safety, or effective targeting to the disease site. In November 2021, Aadi received FDA approval for FYARRO® for the treatment of adult patients with locally advanced unresectable or metastatic malignant perivascular epithelioid cell tumor (PEComa), and in February 2022, Aadi announced the commercial launch of FYARRO in this indication.

Based on exploratory data from AMPECT, a registrational study supporting approval in advanced malignant PEComa, and following a pre-IND meeting with the FDA, Aadi has initiated PRECISION 1, a Phase 2 tumor-agnostic registration-intended trial in mTOR inhibitor-naïve malignant solid tumors harboring TSC1 or TSC2 inactivating alterations.
