Conference call to be held today at 8:30 am EST

LOS ANGELES, Nov. 8, 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 announced financial results for the quarter ended September 30, 2023, and highlighted recent corporate progress.

"The third quarter was marked by strong execution by our Aadi Bio team.  Our PRECISION1 tumor-agnostic trial continued rapid enrollment, and we look forward to sharing an early interim analysis on the first third of patients by mid-December," said Dave Lennon, President and CEO of Aadi Bioscience.  "FYARRO continued to demonstrate the importance of a tumor-targeting mTOR inhibitor for PEComa patients, and we are progressing in our previously announced development strategy with the initiation of new Phase 2 studies for endometrial cancer and in neuroendocrine tumors."

Key Operational Highlights

• PRECISION 1 interim analysis on track for mid-December 2023. Presentation of an interim analysis on the first third of trial participants (n=40) with a minimum of 4.5 months of follow-up is planned for mid-December 2023. The presentation is expected to include safety and investigator-assessed response in approximately 20 patients in each of the TSC1 and TSC2 arms.
  
  
• PRECISION1 catalysts expected in 2024. The trial is expected to reach full enrollment (n=120) with approximately 60 patients per arm in the spring of 2024 with trial completion expected by the end of 2024. Presentation of an additional interim analysis is planned when two-thirds of trial patients reach six months of follow-up, currently anticipated in the third quarter of 2024.
  
  
• Presentations at 2023 EORTC-NCI-AACR International Conference on Molecular Targets and Cancer Therapeutics highlight real-world impact of TSC1 and TSC2 inactivating alterations in cancer. Real-world NGS analysis of nearly 440,000 patients with advanced cancer showed that TSC1 or TSC2 known or likely pathogenic alterations occurred in approximately 2% of all advanced cancers. TSC1 or TSC2 inactivating alterations most commonly occurred in lung, gastrointestinal, genitourinary, breast and gynecological tumors. Posters with this and other related data are available on the Aadi Bio website under "Publications and Abstracts."
  
  
• Dave Lennon, Ph.D., appointed President and CEO. In early October, Aadi announced the appointment of Dave Lennon, Ph.D. as President and Chief Executive Officer. Dr. Lennon brings more than twenty years of experience leading global biotechnology and pharmaceutical teams, with significant expertise in development and commercialization in mTOR-driven diseases.
  
  
• Initiation of Phase 2 combination trial in endometrial cancer. The Phase 2 trial investigating the combination of nab-sirolimus with letrozole for the treatment of advanced or recurrent endometrioid-type endometrial cancer (EEC) has been initiated and is currently enrolling patients. The Company presented a trials-in-progress poster on the EEC Phase 2 study at the International Gynecologic Cancer Society (IGCS) 2023 Annual Global Meeting earlier in November.
  
  
• Initiation of Phase 2 study in neuroendocrine tumors (NETs). The Phase 2 study in neuroendocrine tumors (NETs) has been initiated and is currently enrolling patients. This multicenter, open-label, single-arm trial is evaluating nab-sirolimus in adult patients with functional or non-functional, well-differentiated, locally advanced unresectable or metastatic NETs of the GI tract, lung, or pancreas who have received no more than two prior lines of therapy.

Third Quarter 2023 Financial Results

• Total revenue resulting from sales of FYARRO for the quarter ended September 30, 2023, was $6.0 million. This compares to the prior year period of $4.2 million.
  
  
• Cash, cash equivalents and short-term investments as of September 30, 2023, were $119.3 million as compared to $172.6 million as of December 31, 2022, which is expected to fund operations into 2025 based on current plans.
  
  
• Net loss for the three months ended September 30, 2023, was $16.3 million as compared to $14.5 million for the three months ended September 30, 2022.

About FYARRO®

FYARRO is an mTOR inhibitor indicated for the treatment of adult patients with locally advanced unresectable or metastatic malignant perivascular epithelioid cell tumor (PEComa).

About the PRECISION1 Trial

The PRECISION1 trial is a multi-center, open-label, tumor-agnostic registrational 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 November 2021, the FDA granted Fast Track designation to evaluate nab-sirolimus for this patient population.

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.
