ABSTRACT
Introduction:
Savolitinib has been found to have encouraging antitumor activity and a favorable safety profile in Chinese patients with pulmonary sarcomatoid carcinoma and other NSCLCs with MET exon 14 skipping alterations (MET ex14 positive) at the primary analysis of a phase 2 study. Here, we present the long-term efficacy and safety data of savolitinib, including subgroup analyses.Methods:
This multicenter, single-arm, open-label, phase 2 study in the People's Republic of China enrolled MET inhibitor-naive adults with locally advanced or metastatic METex14-positive NSCLC (NCT02897479). Oral savolitinib at a dose of 400 or 600 mg was administered once daily (body weight dependent). The primary objectives of the final analysis were long-term overall survival (OS) and subgroup analyses by previous systemic treatment, NSCLC subtypes, and brain metastases.Results:
At the final analysis cutoff date (June 28, 2021), a total of 70 patients were enrolled and receiving savolitinib, and median follow-up was 28.4 (interquartile range 26.2-36.3) months. The median OS was 12.5 months (95% confidence interval [CI] 10.5-21.4 [18- and 24-mo OS rates, 42.1% and 31.5%, respectively]). Median OS in pretreated or treatment-naive patients was 19.4 (95% CI 10.5-31.3) and 10.9 (95% CI 7.5-14.0) months, respectively; it was 10.6 months (95% CI 4.6-14.0) in patients with pulmonary sarcomatoid carcinoma, 17.3 months (95% CI 10.6-23.6) in other NSCLC subtypes, and 17.7 months (95% CI 10.5-not evaluable) in patients with brain metastases. No new safety signals emerged with prolonged follow-up and exposure.Conclusions:
The updated results further confirm the favorable benefit and acceptable safety of savolitinib in Chinese patients with METex14-positive NSCLC.
