Frequently asked questions about TRX518 monotherapy

What is TRX518 used for?

TRX518 is an investigational monoclonal antibody being studied for the treatment of unresectable Stage III or Stage IV malignant melanoma and other solid tumor malignancies, as well as solid tumors. It is in Phase 1 clinical development and is not yet approved by regulatory authorities.

What does TRX518 target?

TRX518 is a monoclonal antibody designed to target GITR, a protein involved in immune regulation. By binding to GITR, TRX518 aims to modulate the immune system's response against tumor cells, potentially enhancing anti-tumor activity in patients with certain cancers.

Who is developing TRX518?

TRX518 is being developed by Cypherpunk Technologies Inc., a biopharmaceutical company. The company is conducting clinical trials to evaluate the safety and efficacy of TRX518 in patients with advanced melanoma and other solid tumors.

What phase is TRX518 in?

TRX518 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. Clinical trials are ongoing to assess its safety, tolerability, and potential efficacy in treating certain types of cancer.

What clinical trials is TRX518 in?

TRX518 has been studied in two completed Phase 1 clinical trials. The first trial, NCT01239134, evaluated TRX518 in patients with unresectable Stage III or Stage IV malignant melanoma or other solid tumors. The second trial, NCT02628574, assessed TRX518 as monotherapy and in combination with gemcitabine, pembrolizumab, or nivolumab in patients with solid tumors.

Is TRX518 the same as anti-GITR mAb?

TRX518 is also known as anti-GITR mAb, as it is a monoclonal antibody that targets GITR. In clinical trial records, it is sometimes referred to by this descriptive name. Both names refer to the same investigational drug being developed by Cypherpunk Technologies Inc.
