Sirolimus Albumin-Bound

Fully enrolled registration-intended PRECISION1 trial; two-thirds interim analysis planned for Q3 2024 FYARRO® sales of $5.4 million for Q1 2024, reflects distributor ordering patterns and fewer commercial patient initiations at the start of the year Conference call to be held today at 8:30 am EDT LOS ANGELES, May 8, 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 first quarter ended March 31, 2024, and highlighted recent corporate progress. "I'm pleased to announce that PRECISION1 is now fully enrolled across a broad array of tumor types and our promising development plan continues to gain momentum. We look forward to providing the two-thirds interim analysis in the third quarter, and full results in early 2025. Additionally, the recently initiated Phase 2 trials in EEC and NETs are enrolling well, and we anticipate initial data from these later this year," said Dave Lennon, President and CEO of Aadi Bioscience. "On the commercial side, FYARRO continues to perform well and has cemented its position as the preferred treatment for malignant PEComa after just two years on the market. The impacts to sales in the first quarter are well-understood events and we expect to return to sales growth in Q2." Recent Operational Highlights FYARRO net product sales were $5.4 million in the first quarter of 2024. This decrease of 8.8% from the prior year period reflects impacts from distributor ordering patterns and fewer new patient initiations than the historical average, which we anticipate will correct in subsequent quarters. Registration-intended PRECISION1 trial is now fully enrolled. PRECISION1 is exploring nab-sirolimus in solid tumors with TSC1 or TSC2 inactivating alterations. The two-thirds interim analysis is expected in Q3 2024, and study completion is expected by year-end. Enrollment into two Phase 2 trials ongoing. These tumor specific trials are investigating the potential of nab-sirolimus for difficult-to-treat mTOR-driven cancers: advanced or recurrent endometrioid-type endometrial cancer (EEC) in combination with letrozole, and neuroendocrine tumors (NETs). At Aadi's request, Mirati/Bristol Myers Squibb and Aadi mutually agreed to terminate their collaboration and clinical supply agreement. Aadi is prioritizing investment in its Phase 2 trials in EEC and NETs. The Phase 1/2 trial with Mirati/Bristol Myers Squibb evaluated the combination of nab-sirolimus + adagrasib in non-small cell lung cancer with a KRASG12C mutation. First Quarter 2024 Financial Results Cash, cash equivalents and short-term investments as of March 31, 2024, were $88.3 million as compared to $108.8 million as of December 31, 2023, which is expected to fund operations into Q4 2025 based on current plans. Total revenue for the quarter ended March 31, 2024, was $5.4 million, resulting from sales of FYARRO. Net loss for the three months ended March 31, 2024, was $18.3 million as compared to $15.2 million for the three months ended March 31, 2023.
