Background Concurrent chemoradiotherapy (CCRT) is the standard treatment for patients with locally advanced non–small-cell lung cell cancer (LA-NSCLC). We conducted a phase I/II study of biweekly carboplatin and nab-paclitaxel (nab-PTX) with radiotherapy (RT). Materials and Methods In the phase I part, patients with inoperable stage IIIA/IIIB NSCLC were treated with carboplatin (area under the time-concentration curve, 4) and nab-PTX (60-100 mg/m2) on days 1, 15, and 29. Thoracic RT was administered from day 1 to a total dose of 60 Gy in 30 fractions. In the phase II part, patients were administered carboplatin and nab-PTX on days 1, 15, and 29 at the recommended dose (RD). The primary endpoint of the phase I part was to determine the maximum tolerated dose and the RD. In the phase II part, the primary endpoint was 2-year overall survival (OS) rate, and secondary endpoints were the objective response rate, progression-free survival, OS, and safety profile. Results In the phase I part, although maximum tolerated dose was not obtained, the RD was carboplatin (area under the time-concentration curve, 4) and nab-PTX (100 mg/m2). Of the evaluable 28 patients, the rate of 2-year OS was 67.8% (95% confidence interval, 49.3%-82.1%). The objective response rate was 96.4%, and the median follow-up time was 33.2 months. The median progression-free survival was 18.2 months (95% confidence interval, 13.1 months to not reached). The most common toxicities of grade 3 or higher were neutropenia (60.5%), anemia (14.2%), thrombocytopenia (7.2%), and pneumonitis (3.6%). Conclusions This study achieved the primary endpoint. Biweekly carboplatin and nab-PTX with concurrent RT was well-tolerated and exerted promising antitumor activity.

Nintedanib has been approved for the treatment of idiopathic pulmonary fibrosis (IPF). In addition, in EU countries, nintedanib plus docetaxel is used for patients with advanced non-small cell lung cancer (NSCLC) after first-line chemotherapy. Here, we report a case of advanced NSCLC in a patient with IPF successfully treated with nintedanib monotherapy. A 69-year-old man was diagnosed with NSCLC complicated by IPF. After three lines of chemotherapy, he still had progressive disease. Because his IPF had also progressed, requiring supplemental oxygen, we decided to start best supportive care and introduced nintedanib to treat his IPF. One month later, we observed a partial remission of the primary tumor and pleural disseminations without severe adverse events. Nintedanib monotherapy might therefore be an effective therapeutic choice for NSCLC in patients with IPF who are unable to tolerate cytotoxic chemotherapy. KEY POINTS: Efficacy of nintedanib administered in a NSCLC patient with IPF. Nintedanib monotherapy might be a therapeutic option for NSCLC patients with IPF who are unable to tolerate chemotherapy.

Background Adjuvant chemotherapy with platinum‐based regimens for completely resected early‐stage non‐small cell lung cancer (NSCLC) provides overall survival benefit in several clinical trials. Objectives We conducted this prospective study to evaluate the efficacy and safety of adjuvant chemotherapy with carboplatin and S‐1 for patients with completely resected stage II to IIIA NSCLC. Methods Patients with completely resected stage IIA to IIIA NSCLC were treated with four cycles of carboplatin with area under the concentration time curve of 5 mg/mL/min on day 1 plus S‐1 at 80–120 mg/bodyweight per day for two weeks, followed by one‐week rest as adjuvant chemotherapy. The primary endpoint was the completion rate of three cycles of the treatment. The secondary endpoints were safety and two‐year survival rate. Results A total of 19 patients were enrolled, until the study was terminated prematurely because of fatal pulmonary embolism in two patients. The median number of treatment cycles was three (range: 1–4). The completion rate of three cycles was 78.9% (95% confidence interval [CI]: 56.6–91.4%). Two‐year disease‐free survival rate was 57.8%. Grade 3 or 4 hematological toxicities included neutropenia (26.2%), anemia (5.2%), and thrombocytopenia (15.7%). Grade 3 or 4 nonhematological toxicities were anorexia (10.5%) and nausea (10.5%). Febrile neutropenia developed in 5.2%. In two patients (10.5%), grade five pulmonary embolism was observed, and the causal relationship with treatment could not be denied. Conclusions Carboplatin and oral S‐1 had modest survival benefit, but this regimen was not tolerable in an adjuvant setting because fatal pulmonary embolism occurred in two patients. Key points Carboplatin and oral S‐1 had modest survival benefit but this regimen was not tolerable. Fatal pulmonary embolism occurred in this regimen.

Background: The INPULSIS trials revealed that nintedanib reduced the decline in lung function in patients with idiopathic pulmonary fibrosis. We aimed to evaluate the efficacy and safety of nintedanib in Japanese idiopathic pulmonary fibrosis patients in real-world settings. Method: Medical records of idiopathic pulmonary fibrosis patients, who received treatment with nintedanib in five institutions between July 2015 and June 2017, were reviewed. Patients with % forced vital capacity ⩾50% and % predicted diffusing capacity of the lung carbon monoxide ⩾30% were classified as the moderate group and those with more impaired lung functions as the severe group. Result: Among 158 patients analyzed, 132 (84.6%) were classified as the moderate group and 26 (15.4%) as the severe group. In the moderate group, changes in forced vital capacity in 12 months were significantly different between before and after nintedanib administration (−253 ± 163 vs −125 ± 235 mL; p = 0.0027). In contrast, changes in forced vital capacity in 12 months were not significantly changed by nintedanib treatment in the severe group (−353 ± 250 vs −112 ± 341 mL; p = 0.2374). Incidence of acute exacerbation was higher in the severe group than in the moderate group (30.8% vs 18.9%). The overall survival of the moderate and the severe groups was 17.2 and 10.1 months. Conclusion: In real-world practice, nintedanib showed comparable efficacy to those observed in previous trials. In the severe group, the efficacy of nintedanib might be limited.

e21078 Background: Concurrent chemoradiotherapy (CCRT) is the standard treatment for patients with locally advanced non-small cell lung cell cancer (LA-NSCLC). We previously reported the phase I study of biweekly carboplatin and nab-paclitaxel (nab-PTX) with RT. Recommended dose for phase II study was carboplatin (AUC 4) and nab-PTX (100 mg/m2) (J Clin Oncol 2015 suppl; abstr 7529). Here we report the phase II part designed to assess the efficacy of biweekly carboplatin and nab-PTX with concurrent RT (UMIN000023802). Methods: Patients with inoperable stage Ⅲ NSCLC were treated with carboplatin (AUC 4) and nab-PTX 100 mg/m2 on days 1, 15, and 29. Thoracic radiotherapy was administered from day 1 to a total dose of 60 Gy in 30 fractions. Consolidation chemotherapy after CCRT was 2 cycles of carboplatin (AUC 6) on day 1 and nab-PTX 100 mg/m2 on days 1, 8, and 15. The primary endpoint for the phase II part is 2-year overall survival (OS) rate. Assuming an expected survival rate was 60% and a lower limit was 35% (alfa 0.05, beta 0.2). Secondary endpoints were the objective response rate (ORR), progression-free survival (PFS), OS, and safety profile. Results: A total of 28 patients (median age 66 years, male 94%) were enrolled. Of the evaluable patients (n = 28), the rate of 2-year OS was 67.8% (95% CI: 49.3–82.1). The ORR was 96%, a median follow-up time was 33.2 months. Median PFS was 18.2 months (95% CI 13.1–not reached), and median OS was not reached (95% CI, 25.6–not reached). The most common toxicities of grade 3 or higher were neutropenia (60.5%), anemia (14.2%), thrombocytopenia (7.6%) and pneumonitis (3.6%). Conclusions: This study achieved the primary endpoint. Biweekly carboplatin and nab-PTX with concurrent RT therapy was well tolerated and promising systemic antitumor activity for patients with LA-NSCLC. Clinical trial information: 000023802 .
