Abstract:
Objective To evaluate the efficacy and safety of treatments in phase Ⅰ oncology clinical trials in patients with advanced non-small-cell lung cancer (NSCLC).
Methods We retrospectively analyzed the clinical data of 65 patients with advanced NSCLC who received phase Ⅰ antitumor trial drugs at the Clinical Trial Research Center of The First Affiliated Hospital of Bengbu Medical University from January 2020 to December 2023. The efficacy and occurrence of serious adverse events (SAEs) were analyzed.
Results The objective response rate (ORR) and disease control rate (DCR) were 9.2% and 61.4%, respectively, whereas the median progression-free survival (PFS) and overall survival (OS) were 2.9 and 15.1 months, respectively. Previously receiving second-line or more lines of treatment and SAE occurrence were independent risk factors for a shorter PFS (P<0.05). A history of smoking and previous second-line or more lines of treatment were independent risk factors for a shorter OS (P<0.05). The SAE incidence was 15.4%, and no treatment-related deaths occurred.
Conclusions Treatments in phase Ⅰ oncology clinical trials are beneficial for patients with advanced NSCLC. Patients with a higher number of previous treatment lines and those who experienced SAEs during the trial had a shorter PFS, whereas patients with no smoking history and fewer previous treatment lines had a longer overall survival. The overall safety of the treatments was acceptable.
