Abstract
Rationale: A fatal acute exacerbation (AE) occasionally develops during chemotherapy for small cell lung cancer (SCLC) with comorbid idiopathic pulmonary fibrosis (IPF).Objectives: This study aimed to assess the safety and efficacy of carboplatin, etoposide, and nintedanib combination therapy for unresectable SCLC with comorbid IPF.Methods: The NEXT-SHIP study is a multicenter, single-arm, phase 2 trial for unresectable SCLC with IPF (Japan Registry of Clinical Trials registry number jRCTs031190119). The patients received carboplatin, etoposide, and nintedanib (150 mg twice daily). The primary endpoint was the incidence of IPF-AE at 28 days after the last administration of cytotoxic chemotherapy, and the sample size was set at 33 (5.0% expected, 20.0% threshold).Results: A total of 33 patients were registered; 87.9% were male, the median age was 73 years, the median percentage forced vital capacity was 85.2%, and 51.5% had honeycomb lungs. The median observation period was 10.5 months. The incidence of IPF-AE at 28 days after the last administration of cytotoxic chemotherapy was 3.0% (90% confidence interval [CI], 0.2-13.6). The objective response rate was 68.8% (95% CI, 50.0-83.9). The median progression-free survival and overall survival times were 4.2 months (95% CI, 4.2-5.5) and 13.4 months (95% CI, 8.1-21.6), respectively. The most common adverse event of grade 3 or higher was neutropenia (81.8%), followed by leukopenia (39.4%) and thrombocytopenia (30.3%).Conclusions: This study met its primary endpoint regarding the incidence of IPF-AEs with promising results for efficacy. Carboplatin, etoposide, and nintedanib combination therapy may be one of the standard treatment options for SCLC with comorbid IPF.Clinical trial registered with the Japan Registry of Clinical Trials (jRCTs031190119).
