Continued growth in total revenue on FYARRO® with sales of $6.2 million for 2Q 2023

On-track for interim analysis on 40 patients in PRECISION1 trial before the end of 2023

Expanding pipeline to include programs in Endometrial Cancer and Neuroendocrine Tumors (NETs)

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

LOS ANGELES, Aug. 9, 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 provided a corporate update and announced financial results for the second quarter of 2023.

"We are seeing continued growth in FYARRO sales and are pleased with the positive feedback we are receiving from the treatment community," said Scott Giacobello, Interim CEO and President and CFO of Aadi. "The PRECISION1 trial is progressing well, and we are looking forward to providing results of an interim analysis on 40 patients with appropriate follow-up before the end of the year.  We expect to complete enrollment as planned in the spring of 2024."

"With PRECISION1 on track, we are excited to announce the expansion of our pipeline to further investigate mTOR pathway inhibition in endometrial cancer and NETs," continued Giacobello. "We are encouraged by the positive feedback received from clinicians, and we believe our preclinical data supporting these programs is promising.  We look forward to harnessing the unique pharmacology of nab-sirolimus, both in combination and as monotherapy, to provide enhanced therapeutic benefit in these indications with meaningful patient populations and high unmet need." 

Second Quarter 2023 Updates and Recent Operational Highlights

• Interim analysis from PRECISION1 expected before the end of 2023.   An interim analysis from the tumor agnostic PRECISION1 trial on 40 patients with appropriate follow-up is on track with data expected before the end of 2023.  Enrollment continues to be well-balanced between the two arms, and as previously reported, more than 15 discrete tumor types have been enrolled, supporting the thesis that TSC1 and TSC2 alterations occur broadly across different solid tumors.
• FYARRO net product sales were $6.2 million in the second quarter, reflecting growth of approximately 6% over Q1 2023 and 80% over the prior year quarter.
• Planned initiation of Phase 2 combination trial in endometrial cancer.  The Company is initiating a Phase 2 trial investigating the combination of nab-sirolimus with letrozole for the treatment of advanced or recurrent endometrioid-type endometrial cancer (EEC).  This is a Phase 2 open-label, multi-institutional study to evaluate the efficacy and safety of nab-sirolimus and letrozole in patients with advanced or recurrent endometrioid endometrial carcinoma.  Prior clinical studies with mTOR inhibitors and letrozole in endometrial cancer patients have yielded promising results. In preclinical models, intravenous nab-sirolimus demonstrates significantly higher tumor growth inhibition, intra-tumoral drug accumulation, and greater mTOR target suppression compared with oral inhibitors. The Company is exploring whether the combination of nab-sirolimus with endocrine therapy may produce synergistic anti-tumor activity in patients with EEC. Initiation of this trial is expected in the fourth quarter of 2023.
• Planned initiation of Phase 2 study in neuroendocrine tumors (NETs).  The Phase 2 study is a multicenter, open-label, single-arm trial that is evaluating 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.  In preclinical animal models, nab-sirolimus demonstrated improved target suppression relative to similar weekly doses of sirolimus and everolimus, supporting further exploration of nab-sirolimus in NETs.  Initiation of this trial is expected in the fourth quarter of 2023.
• Initiated Phase 1/2 trial in KRAS^G12C in collaboration with Mirati Therapeutics.  The first patient has been dosed in a Phase 1/2 trial evaluating the combination of adagrasib with nab-sirolimus in this collaborative study. The open-label Phase 1/2 trial is intended to determine the optimal dose and recommended Phase 2 dose in patients with KRAS^G12C mutant solid tumors.
• Multiple posters presented at ASCO Annual Meeting 2023.  Aadi presented a company-sponsored TIP update from the PRECISION1 Phase 2 study and combination data of nab-sirolimus and pazopanib (PAZO) from an ongoing Investigator Initiated Trial at ASCO 2023.  The posters are available on the investor relations page of the Aadi website at www.aadibio.com.

Second Quarter 2023 Financial Results

• Total revenue resulting from sales of FYARRO for the quarter ended June 30, 2023, was $6.2 million. This compares to the prior year period of $3.4 million.
• Cash, cash equivalents and short-term investments as of June 30, 2023, were $134.9 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 June 30, 2023, was $18.0 million as compared to $18.3 million for the three months ended June 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.
