Abstract

To assess the efficacy and toxicity of Lobaplatin (LBP) -contained chemotherapy on extensive stage small-cell lung cancer (ES-SCLC), we conducted a prospective, single-arm, and multicenter Phase IV clinical trial on Lobaplatin (ChiCTR-ONC-13003471), and used the patient clinical data obtained from our cancer center to perform the analysis. Previously untreated patients with ES-SCLC were given LBP intravenously (IV) at 30 mg/m2 on day 1 and etoposide IV at 100 mg/m2 on day 1, 2, and 3. The treatment was cycled every 21 days, lasting for four to six cycles. The patients with second-line treatment or above were also included in the study, and they were treated with LBP-contained regimen: a single dose of LBP at 50 mg/m2 on day 1 through IV; combined application, LBP30 mg/m2 IV on day 1. From May 2015 to August 2016, 36 patients were enrolled in the study at our cancer center. For the 30 first-line patients, the median overall survival (OS) and the median progression-free survival (PFS) was 13.0 months (ranging from 11.2 to 14.7 months) and 4.7 months (ranging from 1.6 to 7.7 months) respectively, with overall response rate of 57 % and disease control rate of 85.7%. For the 6 patients with second-line treatment or above, one patient got a partial response (PR) and four patients got a stable disease (SD). The most frequent drug-related adverse effects were leukopenia and neutropenia, and no grade 3/4 hepatotoxicity or nephrotoxicity was observed. These results indicated that LBP-contained chemotherapy was effective and tolerable for extensive stage SCLC in terms of response and survival. However, due to the small sample size of this study, we need to wait for the OS data of phase Ⅲ clinical trial and the final data of this multicenter Phase IV study to draw the conclusion.
