Aadi Bioscience Provides PRECISION1 Trial and Corporate Updates

Rhea-AI Summary

Aadi Bioscience (NASDAQ: AADI) has announced the halt of its PRECISION1 trial for nab-sirolimus in solid tumors with TSC1 or TSC2 alterations due to unlikely regulatory approval. The company will now focus on its FYARRO® commercial business for PEComa and conduct a strategic review. To extend cash runway into at least 2H 2026, Aadi will:

• Adjust ongoing Phase 2 trials
• Reduce R&D headcount by 80%
• Pause new enrollment in EEC and NET trials
• Continue dosing previously enrolled patients

FYARRO® sales reached $6.2M in Q2. The company will provide a full analysis of the PRECISION1 trial later and has hired an advisory firm to explore options for maximizing shareholder value.

Positive

• FYARRO® delivered sales of $6.2M in Q2 2024
• Cash runway extended into at least 2H 2026
• Sufficient patients enrolled in EEC (n=20) and NET (n=10) trials to assess initial efficacy signals later this year

Negative

• PRECISION1 trial halted due to unlikely regulatory approval
• R&D workforce reduced by 80%
• New enrollment paused in Phase 2 trials for EEC and NETs

Oncology Researcher

The halt of the PRECISION1 trial is a significant setback for Aadi Bioscience. The trial's failure to meet the efficacy threshold for accelerated approval in TSC1/TSC2 mutated solid tumors limits the company's near-term growth prospects. However, it's important to note that nab-sirolimus did show some monotherapy activity, which may still hold value for future research or targeted applications.

The decision to continue dosing in the endometrial cancer (EEC) and neuroendocrine tumor (NET) trials is prudent. With 20 and 10 patients enrolled respectively, these studies may still yield valuable efficacy data later this year. This could potentially open new avenues for FYARRO beyond its current PEComa indication, albeit on a longer timeline.

Financial Analyst

Aadi's strategic pivot demonstrates responsible financial management in the face of a clinical setback. The 80% reduction in R&D workforce and halting of new enrollments will significantly reduce cash burn. This extends the company's cash runway into at least 2H 2026, providing a substantial buffer for strategic realignment.

The focus on FYARRO's commercial performance is critical. With $6.2 million in Q2 sales for PEComa, there's a foundation to build upon. However, investors should closely monitor future quarters to assess growth trajectory in this niche market. The engagement of an advisory firm signals openness to various strategic options, which could include partnerships, asset sales, or even a potential company sale to maximize shareholder value.

PRECISION1 tumor-agnostic trial unlikely to meet regulatory threshold to support an accelerated approval and will be halted

Aadi will focus on FYARRO^® commercial business for its approved indication, PEComa, and conduct a comprehensive strategic review to maximize shareholder value

To further preserve cash position, Aadi will adjust ongoing Phase 2 trials and reduce R&D headcount by 80%, thereby extending cash runway into at least 2H 2026

LOS ANGELES, Aug. 20, 2024 /PRNewswire/ -- Aadi Bioscience, Inc. (NASDAQ: AADI) today announced it will halt the registration-intended PRECISION1 trial of nab-sirolimus in patients with solid tumors harboring TSC1 or TSC2 inactivating alterations. An analysis by the Independent Data Monitoring Committee demonstrated that the study was unlikely to exceed an efficacy threshold necessary to support an accelerated approval, the key goal of this Phase 2 study.  The approximately 25 patients in PRECISION1 who are still benefiting from nab-sirolimus will be eligible for transition to a planned expanded access protocol, and a complete analysis of the PRECISION1 trial will be provided at a later date.

Aadi will now focus on preserving cash while maximizing its commercial business.  Aadi's marketed product, FYARRO^®, is the only preferred treatment for patients with advanced malignant PEComa, a rare and aggressive cancer.  In the second quarter of this year, FYARRO delivered sales of $6.2M.

To further preserve cash runway, Aadi will pause new enrollment, but continue dosing previously enrolled patients, in two, ongoing Phase 2 trials of nab-sirolimus for advanced or recurrent endometrioid-type endometrial cancer (EEC) and neuroendocrine tumors (NETs). Both studies have enrolled sufficient patients (n=20 and n=10 for EEC and NETs, respectively) to assess initial efficacy signals later this year.  Aligned to these pipeline adjustments, the Company is reducing its Research & Development workforce by 80%.  Together these actions extend cash runway into at least 2H 2026.

"We are humbled by the effort of the investigators, support staff, and most importantly, the patients and their families who took part in PRECISION1. While nab-sirolimus showed monotherapy activity in the study population, the trial fell short of delivering what we believe would be required to support an accelerated approval in the broad TSC1/TSC2 inactivating mutations indication. We look forward to providing the full trial analysis at a later date," said David Lennon, President and CEO of Aadi Bioscience. "I want to thank the dedicated Aadi employees who worked tirelessly on this trial and are negatively impacted by this outcome. Given the change in the development pipeline, we have taken the necessary steps to immediately preserve cash runway, and have hired an advisory firm to explore all options to maximize value for shareholders."
