Part A: Number Of Participants Experiencing Adverse Events (AEs)Primary· From Day 1 up to 4 years and 7 months
An AE was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study drug, whether considered related to study drug or not. All AEs reported are treatment-emergent, which was defined as having a reported onset time or worsening in severity on or after the date of the first dose of study treatment through 30 days after the last dose (permanent discontinuation of study treatment) or initiation of new anticancer therapy. A summary of serious and all other non-serious AEs, regardl

Part A: Number Of Participants Experiencing Dose-limiting Toxicity (DLT)Primary· 21 days following the first dose of tislelizumab and pamiparib in Cycle 1
DLT was defined as an AE or abnormal laboratory value assessed as unrelated to disease progression, intercurrent illness, or concomitant medications, and occurs during the first 21 days following the first dose of tislelizumab and pamiparib in Cycle 1 and meets protocol-specified criteria. A summary of serious and all other non-serious AEs, regardless of causality, is located in the Reported Adverse Events module.

Time frame: Day 1 through 4 years and 7 months.
Reporting threshold: 3%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
This trial studied the safety, pharmacokinetics, and antitumor activity of the anti-programmed cell death 1 (PD-1) monoclonal antibody (mAb) BGB-A317 (tislelizumab) in combination with the poly(adenosine diphosphate ribose) polymerase (PARP) inhibitor BGB-290 (pamiparib) in participants with advanced solid tumors.
