[14-December-2023] |
Interim results from investigator-assessed responses in first 40 patients from TSC1 and TSC2 arms demonstrate sustained tumor reductions in heavily pre-treated population 80 patients now enrolled in PRECISION1 supporting two-thirds interim analysis expected in 3Q 2024 Study on track for completion by end 2024; final data readout expected in early 2025 Company to host conference call today at 5:00 pm EST LOS ANGELES, Dec. 14, 2023 /PRNewswire/ -- Aadi Bioscience, Inc (NASDAQ: AADI), a biopharmaceutical company focused on developing and commercializing precision therapies for genetically defined cancers with alterations in mTOR pathway genes, today reported results from a planned interim analysis on the first third of participants in the ongoing tumor-agnostic PRECISION1 trial evaluating nab-sirolimus in patients with TSC1 or TSC2 inactivating alterations. “Our tumor agnostic PRECISION1 trial is designed to elucidate the impact of nab-sirolimus on cancers expressing inactivating alterations of TSC1 or TSC2, regardless of tumor type. We are encouraged by the preliminary data from this pre-planned analysis and by the responses and clinical benefit demonstrated in advanced cancer patients who have failed an average of three prior lines of therapy,” said Loretta Itri, MD, CMO of Aadi Bioscience. “Full enrollment in the trial is expected by the spring of 2024 and we believe we are on track to generate compelling clinical evidence for advancing nab-sirolimus toward potential expansion of the current registration, bringing this innovative therapeutic agent to more cancer patients.” The interim analysis includes data from the first third of trial participants (n=40) with a minimum of 4.5 months of follow-up, including investigator-assessed response and safety analyzed separately in each of the TSC1 and TSC2 arms. Nine different tumor types were enrolled in the TSC1 arm and 13 tumor types were enrolled in the TSC2 arm. Efficacy of nab-sirolimus in patients with tumors harboring pathogenic inactivating alteration in TSC1 Of the 22 patients enrolled, 19 patients received ≥ 1 post baseline scan and were evaluable for efficacy. Observations included:
Efficacy of nab-sirolimus in patients with tumors harboring pathogenic inactivating alteration in TSC2 Of the 18 patients enrolled, all 18 patients received ≥ 1 post baseline scan and were evaluable for efficacy. Observations included:
No new safety signals were observed, and no grade four treatment-related events or deaths occurred. One patient discontinued the study due to grade two pneumonitis that completely resolved after discontinuation of therapy. Across both arms, the safety profile was consistent with the nab-sirolimus label and the mTOR inhibitor drug class. 80 patients are currently enrolled in the PRECISION1 trial, supporting the two-thirds interim analysis expected in the third quarter of 2024. The ORR analysis in this cohort will be based on independent radiological review with a minimum of six months of follow-up for all patients. The trial is expected to be completed by the end of 2024 with results anticipated in early 2025. Conference Call Information The Aadi management team is hosting a conference call and webcast today at 5:00 pm ET (2:00 pm PT) to discuss the interim results from the PRECISION1 trial. Participants may access a live webcast of the call and the associated slide presentation on these data through the “Investors & News” page of the Aadi Bioscience website at aadibio.com. To participate via telephone, please register in advance at this link. Upon registration, all telephone participants will receive a confirmation email detailing how to join the conference call, including the dial-in number along with a unique passcode and registrant ID that can be used to access the call. A replay of the conference call and webcast will be archived on the Company’s website for at least 30 days. About PRECISION1 The PRECISION1 trial is a multi-center, open-label, tumor-agnostic prospective registration intended clinical trial of nab-sirolimus. This tumor agnostic study will evaluate approximately 60 mTOR inhibitor naïve patients in each of two independent study arms, or approximately 120 in total, comprised of patients with solid tumors harboring pathogenic inactivating alterations in either TSC1 or TSC2 genes. In September 2021, the FDA designated the investigation of nab-sirolimus for the treatment of adults and adolescents with solid tumors that have a pathogenic inactivating alteration of the TSC1 or TSC2 gene as a Fast Track development program. Nab-Sirolimus 100 mg/m2 is given weekly intravenously over 30 minutes on Days 1 and 8 of each 21-day cycle. The primary endpoint is overall response rate per independent radiographic review (IRR) using RECIST v1.1. Other endpoints include duration of response, time to response, progression-free survival by IRR, overall survival, patient-reported quality of life, and safety. About Aadi Bioscience Aadi is a commercial-stage biopharmaceutical company focused on precision therapies for genetically defined cancers to bring transformational therapies to cancer patients with mTOR pathway driver alterations. Aadi received FDA approval and has commercialized FYARRO® for the treatment of adult patients with locally advanced unresectable or metastatic malignant perivascular epithelioid cell tumor (PEComa). Aadi has also initiated PRECISION1, a Phase 2 tumor-agnostic registration-intended trial in mTOR inhibitor-naïve malignant solid tumors harboring TSC1 or TSC2 inactivating alterations.
