Frequently asked questions about GCC2005

What is GCC2005 used for in T-cell lymphoma?

GCC2005 is an investigational therapy being studied for the treatment of relapsed or refractory T-cell lymphoma, including NK and T-cell malignancies. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does GCC2005 target?

GCC2005 targets CD5, a protein expressed on certain immune cells. By targeting CD5, the drug is designed to address malignant T-cells in conditions like T-cell lymphoma. This mechanism is being evaluated in early-stage clinical trials for safety and efficacy.

Who is developing GCC2005?

GCC2005 is being developed by Artiva Biotherapeutics, Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol ARTV. The company is conducting clinical research to evaluate the drug's potential in treating T-cell malignancies.

What phase is GCC2005 in?

GCC2005 is in Phase 1 clinical development. This early-stage trial is designed to investigate the safety, tolerability, and efficacy of the drug in patients with relapsed or refractory NK and T-cell malignancies. It is not yet approved for commercial use.

What clinical trials is GCC2005 in?

GCC2005 is being studied in a Phase 1 clinical trial registered as NCT06699771. This open-label, uncontrolled study is recruiting participants in South Korea and aims to enroll approximately 53 patients with T-cell lymphoma and related malignancies. The trial is currently active and recruiting.
