What was measured

The following toxicities were considered to be treatment limiting toxicities: any \>=Grade 4 AE; Grade 3 non-infectious pneumonitis and any other Grade 3 AE (excluding pneumonitis), that did not improve to Grade 2 within 7 days after onset despite medical management and supportive care. Exceptions included the following: Grade 3 or 4 leukopenia, lymphopenia, neutropenia, or febrile neutropenia; Grade 3 or 4 thrombocytopenia not associated with significant bleeding; Grade 3 anemia; Grade 4 cytokine release syndrome (CRS) or toxicities related to CRS that resolved to Grade \<=2 within 7 days; other Grade 3 laboratory abnormality determined to be not clinically significant by the Investigator; Grade 3 or 4 fever and chills; Grade 3 or 4 hypoalbuminemia or abnormal electrolytes that responded to supplementation/correction; AE related to the cancer or its progression.

Analysis population: ITT Population. Treatment limiting toxicities were assessed in GSK3377794+pembrolizumab arm only.

Groups in this outcome

GSK3377794+Pembrolizumab

Eligible participants underwent leukapheresis to manufacture engineered T-cells. Participants then underwent lymphodepleting chemotherapy with cyclophosphamide and fludarabine followed by a single IV infusion of GSK3377794 in combination with pembrolizumab 200 milligrams (mg) administered as an IV infusion every 3 weeks up to Week 108.
