The Impact of Thymosin α-1 on the Efficacy of Concurrent Chemoradiotherapy Followed by Immunotherpay Consolidation for Locally Advanced NSCLC

Participants were treated with definitive thoracic radiotherapy

All participants receive two cycles of albumin-bound paclitaxel (260mg/m2) on d1 and cisplatin (25mg/m2) from d1 to d3 in combination with tislelizumab (200mg) on d1.

Concurrent chemotherapy consists of weekly albumin-bound paclitaxel (50mg/m2) and cisplatin (25mg/m2).

Participants without disease progression, grade ≥3 toxicities, and/or grade ≥2 pneumonitis after CCRT receive tislelizumab 200 mg (Q3W) for up to 12 months.

"Participants in the Tα1 treatment group will receive Tα1 from the beginning of induction chemo-immunotherapy until the completion of immunotherapy consolidation. In detail, Tα-1 would be administered according to the following three stages:~1. Induction chemo-immunotherapy: Tα-1 will be subcutaneously administered at 4.8 mg on d1 and d3 for each cycle.~2. Concurrent chemoradiotherapy: Tα-1 will be subcutaneously administered at 4.8mg biweekly.~3. Immunotherpay consolidation: Tα-1 will be administered concurrently with tislelizumab at 4.8mg (Q3W) for up to 12 months."
