Aadi Bioscience Appoints Brendan Delaney as Chief Operating Officer

LOS ANGELES, Sept. 20, 2021 Aadi Bioscience, Inc. ( Aadi ) (Nasdaq: AADI), a clinical-stage biopharmaceutical company focusing on precision

therapies for genetically-defined cancers with alterations in mTOR pathway genes, today announced the appointment of Brendan Delaney to the role of Chief Operating Officer (COO). Brendan has had an established career in oncology-focused commercial

leadership roles, launching multiple groundbreaking new products and building effective and cohesive commercial teams. Most recently Brendan was Chief Commercial Officer at Constellation Pharmaceuticals, which was acquired by MorphoSys AG for

$1.4 billion prior to a commercial launch of pelabresib a first-in-class BETi inhibitor with blockbuster potential across multiple hematology indications. Prior to

this, as Chief Commercial Officer at Immunomedics, Inc. Brendan led the launch of TRODELVY , the first TROP-2 directed antibody-drug conjugate for the

treatment of triple-negative breast cancer which was acquired by Gilead Sciences, Inc. for $21 billion.

Brendan and I collaborated closely

when I was Executive Chairman of Immunomedics to bring TRODELVY to market, and I am delighted to be reunited with Brendan in his new capacity as Aadi becomes a fully integrated biopharmaceutical company, stated Behzad Aghazadeh, Ph.D.,

Managing Partner and Portfolio Manager, Avoro Capital and member of Aadi s Board of Directors. Brendan has a stellar track record of bringing orphan oncology drugs to market, leading commercial teams at three major oncology companies that

have now been acquired. Aside from being an invaluable addition to the Company at this time, Brendan will also establish Aadi s presence on the East Coast since he is based in the tri-state area .

We are delighted that Brendan has accepted the role of COO. His commercial expertise will be critical as we get ready to launch ABI-009 for malignant PEComa and expand our focus to the broader applications of this exciting product , stated Neil Desai, Chief Executive Officer of Aadi. In his role as COO we will be able to leverage

his extensive leadership experience to build out across various functions in this important growth phase of the Company.

Mr. Delaney began his

career at Bristol-Myers, Genentech and Chiron in roles of increasing responsibility in oncology marketing and strategy, and led global branding, strategy and franchises in Novartis oncology division for blockbuster brands. At Immunomedics,

Mr. Delaney led the build-out of the marketing, sales, market access and commercial operations teams related to TRODELVY. Prior to his Chief Commercial Officer roles at Constellation and Immunomedics,

Mr. Delaney was Vice President, U.S. Commercial Hematology Oncology of Celgene Corporation, prior to its acquisition by Bristol-Myers Squibb in 2019.

Mr. Delaney commented, I am thrilled to join Aadi at this pivotal time ahead of the

November 26, 2021 Prescription Drug User Fee Act (PDUFA) target date of its investigational candidate, ABI-009 for PEComa. I look forward to leveraging my commercialization expertise to bring this

promising investigational candidate to market, and to maximize the utility of the nab-sirolimus technology platform in tumor agnostic indications such as in patients with solid tumors harboring TSC1 or TSC2 inactivating

alterations, for which we plan to initiate a registrational trial by year-end.

About Aadi Bioscience and FYARRO

Aadi is a clinical-stage biopharmaceutical company developing precision therapies for

genetically-defined cancers. Aadi s primary goal is to bring transformational therapies to cancer patients with mTOR pathway driver alterations such as alterations in TSC1 or TSC2 genes, where other mTOR inhibitors have not

or cannot be effectively exploited due to problems of pharmacology, effective drug delivery, safety, or effective targeting to the disease site. Aadi s lead product candidate is

FYARROTM (sirolimus albumin-bound nanoparticles for injectable suspension; nab-sirolimus; ABI-009), an mTOR inhibitor bound to human albumin that

has demonstrated significantly higher tumor accumulation, greater mTOR target suppression, and increased tumor growth inhibition over other mTOR inhibitors in preclinical models2.

Aadi s registration trial of FYARRO in advanced malignant PEComa (the AMPECT trial ) demonstrated meaningful clinical efficacy in malignant

PEComa1, a type of cancer with the highest known alteration rate of TSC1 or TSC2 genes. FYARRO has received Breakthrough Therapy, Fast-Track and Orphan Designations from the

U.S. Food and Drug Administration (FDA). A rolling New Drug Application (NDA) submission was completed in May 2021 for this indication and the FDA accepted the NDA in July 2021 and granted Aadi Priority Review status with a Prescription Drug User

Fee Act ( PDUFA ) target action date of November 26, 2021.

Based on the AMPECT trial and emerging data for FYARRO in other solid tumors

with TSC1 or TSC2 inactivating alterations3, and following discussions with the FDA, Aadi plans to initiate a tumor-agnostic registrational trial in mTOR inhibitor-na ve solid tumors harboring TSC1 or TSC2 inactivating alterations by the end of 2021. Aadi also has ongoing studies to evaluate dosing of FYARRO in combination regimens. FYARRO is

an investigational drug that has not been approved by the FDA for commercial distribution in the United States. More information is available on the Aadi website at www.aadibio.com.
