Frequently asked questions about NY-ESO-1 Peptide vaccine

What is NY-ESO-1 Peptide vaccine used for?

NY-ESO-1 Peptide vaccine is being studied for use in ovarian cancer, specifically in patients with Stage IV ovarian cancer. The investigational therapy is part of a combination strategy being evaluated in a Phase 2 clinical trial to prevent resistance to anti-PD-1 therapy in metastatic ovarian cancer patients.

Who makes NY-ESO-1 Peptide vaccine?

NY-ESO-1 Peptide vaccine is being developed by Coherus Oncology, Inc., a company traded under the ticker symbol CHRS. The company is conducting a Phase 2 clinical trial of the vaccine in patients with advanced ovarian cancer.

What phase is NY-ESO-1 Peptide vaccine in?

NY-ESO-1 Peptide vaccine is currently in Phase 2 clinical development. It is an investigational therapy, meaning it has not been approved by regulatory authorities and is still being evaluated in clinical trials for safety and efficacy in ovarian cancer.

What clinical trials is NY-ESO-1 Peptide vaccine in?

NY-ESO-1 Peptide vaccine is being evaluated in a single Phase 2 clinical trial with the identifier NCT05479045. The trial, titled "A Combination Therapy Strategy to Prevent Anti-PD-1 Therapy Resistance in Metastatic Ovarian Cancer Patients," is not yet recruiting and plans to enroll 24 female patients in the United States.

What is the target of NY-ESO-1 Peptide vaccine?

NY-ESO-1 Peptide vaccine is designed to target the NY-ESO-1 antigen, a tumor-associated antigen expressed in various cancers. By targeting this antigen, the vaccine aims to stimulate an immune response against cancer cells, potentially helping to prevent resistance to anti-PD-1 therapy in ovarian cancer patients.
