Study of Tislelizumab, Pamiparib, and Other Investigational Agents in Participants With Advanced Malignancies

For the purposes of this study, "study treatment" will refer to all investigational agents. A parent study is defined as the original BeiGene- or BeOne-sponsored clinical trial in which the participant was initially enrolled and received BeiGene or BeOne investigational drugs (with or without other treatments). Note: Our company, previously known as BeiGene, is now officially BeOne Medicines. Because some of our older studies were sponsored under the name BeiGene, you may see both names used for this study on this website.
