This clinical trial is focused on studying a type of cancer known as Head and Neck Squamous Cell Carcinoma. This cancer affects areas such as the mouth, throat, and voice box. The study is exploring the use of a medication called Tislelizumab, which is given through an intravenous infusion, meaning it is delivered directly into the bloodstream through a vein. Tislelizumab is being tested in combination with other investigational agents, which are new treatments that are still being studied and are not yet approved for general use. These investigational agents include BGB-A425 and LBL-007, both of which are also administered through intravenous infusion.
The purpose of this study is to assess the antitumor activity of Tislelizumab when used with these investigational agents. Participants in the study will receive these treatments to see how well they work in controlling the cancer. The study will involve multiple groups, with some participants receiving Tislelizumab alone and others receiving it in combination with one or more of the investigational agents. The study will monitor the response of the cancer to these treatments over a period of time, which can last up to 24 months.
Throughout the study, researchers will observe how the cancer responds to the treatment, including whether it shrinks or stops growing. They will also monitor the participants’ overall health and any side effects they may experience. The study aims to provide valuable information on the effectiveness and safety of these treatments for people with recurrent or metastatic head and neck cancer, which means the cancer has returned or spread to other parts of the body.
