LOS ANGELES, March 13, 2024 /PRNewswire/ -- Aadi Bioscience, Inc. (NASDAQ: AADI), a commercial-stage, precision oncology company focused on developing and commercializing therapies for cancers with alterations in the mTOR pathway, today announced financial results for the fourth quarter and full-year ended December 31, 2023, and highlighted recent corporate progress.

"With strong execution against our commercial and development goals, 2023 was a year of progress and momentum for Aadi," said Dave Lennon, President and CEO of Aadi Bioscience. "As the preferred treatment for malignant PEComa, FYARRO saw significant growth and high penetration in academic and community settings. Clinically, we were encouraged by the interim results from the registration-directed PRECISION1 trial, and look forward to the two-thirds readout expected in Q3. We also initiated enrollment of two Phase 2 trials in what we believe are promising mTOR-driven cancer targets, endometrial cancer and neuroendocrine tumors, as we further characterize the potential of nab-sirolimus. With a commercial foundation, bold development vision and solid cash runway in to Q4 2025, we believe we are well-positioned to realize our ambition of becoming a multi-indication precision oncology company."

Recent Operational Highlights

• FYARRO net product sales were $6.3 million in the fourth quarter, or 21% growth over the prior year period, and $24.4 million for full-year 2023, representing 60% growth year-over-year.
• PRECISION1 on track to complete enrollment by May 2024, with the two-thirds interim analysis expected in Q3 2024. Early data presented in December 2023 demonstrated sustained tumor reductions in heavily pre-treated population from investigator-assessed responses in first 40 patients across both arms. The safety profile was consistent with the nab-sirolimus label and the mTOR inhibitor drug class.
• Enrollment of two single-indication Phase 2 trials underway to investigate the potential of nab-sirolimus for difficult-to-treat mTOR-driven cancers: neuroendocrine tumors (NETs), and advanced or recurrent endometrioid-type endometrial cancer (EEC) in combination with letrozole.
  • NETs are rare, ~3,500 cases a year, with low response rates to existing recommended treatments. Preclinical models indicate improved target suppression relative to other mTORs in the NETS population.
  • Endometrial cancer is the most common cancer of the female reproductive organs and one of the few cancers with increasing mortality. There are an estimated 10,000 cases of EEC diagnosed annually. Prior clinical studies with mTOR inhibitors and letrozole have yielded promising results in EEC.

Fourth Quarter and Full-year 2023 Financial Results

• Cash, cash equivalents and short-term investments as of December 31, 2023, were $108.8 million as compared to $172.6 million as of December 31, 2022, which is expected to fund operations into Q4 2025 based on current plans.
• Total revenue for the quarter ended December 31, 2023, was $6.3 million, and $24.4 million for the full-year ended December 31, 2023, resulting from sales of FYARRO.
• Net loss for the three months ended December 31, 2023, was $16.3 million as compared to $13.9 million for the three months ended December 31, 2022. Net loss for the full-year ended December 31, 2023, was $65.8 million, as compared to $60.5 million for the same period in 2022.
