Background Camrelizumab has shown promising survival benefits in treatment-naïve advanced non-small cell lung cancer (NSCLC) patients when used in combination with chemotherapy. However, its effectiveness and safety outside the clinical trial setting are largely unknown. Therefore, we conducted NOAH-LC-101, a prospective multicenter cohort study, to investigate the real-world effectiveness and safety of camrelizumab on a large cohort of advanced NSCLC patients in daily clinical practice. Methods All consecutive patients aged ≥18 years with confirmed advanced NSCLC scheduled for camrelizumab treatment were screened for inclusion at 43 hospitals in China. The primary outcome was progression-free survival (PFS). The secondary outcomes included overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety. Results Between August 2019 and February 2021, 403 patients were included. The median age of participants was 65 years (range, 27–87 years). There were 57 (14.1%) participants with an Eastern Cooperative Oncology Group performance status (ECOG PS) of ≥2. Most participants received camrelizumab in the second or later lines (68.7%) and plus chemotherapy (64.8%). The median PFS was 12.6 [95% confidence interval (CI): 10.7–17.0] months and median OS was 22.3 months [95% CI: 19.3–not reached (NR)]. The ORR was 28.8% (95% CI: 24.4–33.5%) and DCR was 79.9% (95% CI: 75.7–83.7%). Adverse events of any grade occurred in 348 (86.4%) participants. No new safety signals were identified. Reactive cutaneous capillary endothelial proliferation was observed in 75 (18.6%) patients, all of which were grade 1–2. Conclusions This study demonstrates the effectiveness and safety of camrelizumab in a large sample of real-world NSCLC patients. The results are generally consistent with those previously reported in pivotal clinical trials. This study supports the clinical use of camrelizumab in a broader patient population (ChiCTR1900026089).
