Frequently asked questions about TUB-030

What is TUB-030?

TUB-030 is an investigational small molecule antibody-drug conjugate being developed by Gilead Sciences, Inc. for the treatment of advanced solid tumors. It is currently in Phase 1 clinical development and is not yet approved for any indication. The program is evaluating TUB-030 in a first-in-human study across several tumor types.

What is TUB-030 used for?

TUB-030 is being studied for advanced solid tumors, including head and neck squamous cell carcinoma, small cell lung cancer, non-small cell lung cancer, triple-negative breast cancer, and colorectal cancer. It is investigational and has not been approved for any use. All evaluation to date is within a Phase 1 clinical trial.

What does TUB-030 target?

TUB-030 targets 5T4, a tumor-associated antigen, and is designed as an antibody-drug conjugate. The 5T4 target is expressed on several solid tumor types, which is the basis for studying TUB-030 across the cancer indications in its clinical program. Gilead Sciences is developing the asset.

Who is developing TUB-030?

Gilead Sciences, Inc. is developing TUB-030. The company trades on the Nasdaq under the ticker GILD. Gilead is running the Phase 1 first-in-human study of TUB-030 in patients with advanced solid tumors.

What phase is TUB-030 in?

TUB-030 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA or any other regulatory agency. The ongoing first-in-human study is designed to evaluate the drug in patients with advanced solid tumors.
