Brentuximab vedotin will be administered after diluted with 100 ml normal saline as an IV infusion over approximately 30 minutes on Day 1 of each 21-day cycle at a dose of 1.8 mg/kg. Tislelizumab will be administered after diluted with 100 ml normal saline as an IV infusion over approximately 30 minutes on Day 1 of each 21-day cycle at a fixed dose of 200 mg. The rationale of fixed dose of Tislelizumab is according to the drug description, which is based on previous I/II phase clinical trial results of Tislelizumab. The time interval between administration of tislelizumab and brentuximab vedotin should be not less than 2 hours, and thereafter, the dosing cycle of tislelizumab is synchronized with that of brentuximab vedotin.
