- Tislelizumab + Chemoradiotherapy
- description
- Participants received 200 mg tislelizumab administered intravenously (IV) once every 3 weeks in combination with concurrent chemoradiotherapy (CRT) for up to approximately 6 weeks followed by 200 mg tislelizumab for a total of up to 24 months (about 35 cycles), or until disease progression, unacceptable toxicity, withdrawal of consent, or another treatment discontinuation criterion was met, whichever occurred first. Concurrent chemotherapy consisted of cisplatin (25 mg/m² IV; Days 1-3 of each 3-week cycle) in combination with paclitaxel (135 mg/m² IV; Day 1 of each 3-week cycle) and radiotherapy was delivered in 28 fractions (total dose, 50.4 Gy).
