A Study of ASP1012 in Adults With Solid Tumors
Recruiting
ASP1012 is a type of virus called an oncolytic virus which is used to treat some cancers. ASP1012 was changed in a laboratory to infect and kill cancer cells, leaving healthy cells alone. It also makes the cancer cells visible to the immune system which will fight the cancer cells. Before ASP1012 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This will help find a suitable dose for future studies and check for potential medical pr... Read More

Testing the Addition of BMS-986016 (Relatlimab) to the Usual Immunotherapy After Initial Treatment for Recurrent or Metastatic Nasopharyngeal Cancer
Recruiting
This phase II trial tests the addition of BMS-986016 (relatlimab) to the usual immunotherapy after initial treatment for nasopharyngeal cancer that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to other places in the body (metastatic). Relatlimab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. The usual approach of treatment is initial treatment with chemotherapy such as the co...
