Tislelizumab combined with nab-paclitaxel and cisplatin as the more effective chemoimmunotherapy strategy in the neoadjuvant treatment of locally advanced thoracic esophageal squamous cell carcinoma: A prospective, two-cohort, phase 2 trial.
This prospective, two-cohort phase 2 trial with random allocation was conducted to evaluate the safety and efficacy of neoadjuvant tislelizumab combined with nab-paclitaxel/paclitaxel and cisplatin (TP) in patients with esophageal squamous cell carcinoma (ESCC). Patients were enrolled and randomly assigned to the nab-paclitaxel or paclitaxel cohorts at a 1:1 ratio, and received intravenous tislelizumab (200 mg, day 1) combined with cisplatin (25 mg/m2, days 1-3) and either nab-paclitaxel (125 mg/m2, days 1 and 8) or paclitaxel (150 mg/m2, day 1) in a 21-day cycle for two cycles before surgery. The primary endpoint was the major pathological response (MPR) rate. From March 01, 2022 to April 10, 2023, 46 patients were enrolled (n = 23 in each cohort), with 42 patients receiving the full two-cycle treatments and undergoing surgery (n = 22 in the nab-paclitaxel cohort, n = 20 in the paclitaxel cohort). The MPR rate and the pCR rate in the total cohort were 44.2% (19/42) and 19.0% (8/42), respectively, with 59.1% (13/22) and 31.8% (7/22) in the nab-paclitaxel cohort and 30.0% (6/20) and 5.0% (1/20) in paclitaxel cohorts. The most common treatment-related adverse events (TRAEs) were anemia (89.1%) and alopecia (71.7%), and no significant difference in TRAEs was observed between the two cohorts. Up until March 28, 2024, the median follow-up time was 15.5 months (range of 6.0-24.3 months), and the survival analysis revealed that the patients in the nab-paclitaxel cohort had a higher event-free survival (p = .002). In conclusion, neoadjuvant tislelizumab combined with cisplatin and nab-paclitaxel, rather than cisplatin and paclitaxel, is a more effective neoadjuvant strategy for locally advanced thoracic ESCC.
