Frequently asked questions about ARR-002

What is ARR-002 used for?

ARR-002 is an investigational therapy being studied for advanced or metastatic ovarian cancer, including platinum-resistant ovarian cancer, and for advanced or metastatic endometrial cancer. It is a small molecule in Phase 1 development and has not been approved for any use. All testing to date is in the clinical trial setting.

What does ARR-002 target?

ARR-002 targets MUC16, also known as NaPi2b, a cell surface antigen. MUC16/NaPi2b is expressed on ovarian and endometrial tumor cells, making it an antigen-directed target for this small molecule. Targeting this antigen is the basis for the drug's proposed antitumor activity in the cancers under study.

Who is developing ARR-002?

ARR-002 is being developed by ArriVent BioPharma, Inc., which trades on the Nasdaq under the ticker AVBP. The company is the sponsor of the ongoing Phase 1 clinical program evaluating the agent in ovarian and endometrial cancer.

What phase is ARR-002 in?

ARR-002 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA or any other regulatory agency. The single ongoing study is designed to assess safety, tolerability, pharmacokinetics, immunogenicity, and antitumor activity in patients with advanced disease.

What clinical trials is ARR-002 in?

ARR-002 is being evaluated in one active clinical trial, NCT07755436, a Phase 1 study of safety, tolerability, pharmacokinetics, immunogenicity, and antitumor activity in advanced or metastatic ovarian or endometrial cancer. The trial is currently recruiting in the United States and plans to enroll approximately 180 female participants aged 18 years and older.
