Anlotinib combined with PD-1 blockade for the treatment of lung cancer: a real-world retrospective study in China.

BACKGROUND: This study evaluated the efficacy and safety of anlotinib combined with programmed cell death protein 1 (PD-1) blockade for the treatment of small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: SCLC (n = 28) and NSCLC (n = 177) patients who received treatment at Hunan Cancer Hospital between June 1, 2019, and July 1, 2020, were retrospectively analyzed. Progression-free survival (PFS) and treatment responses were compared among patients who received combination therapy of anlotinib plus PD-1 inhibitor, or monotherapy of either chemotherapy or PD-1 inhibitor. Independent prognostic factors were identified by Cox regression analysis. RESULTS: Patients with relapsed SCLC who received anlotinib plus PD-1 inhibitor as a ≥ second-line therapy (n = 14) had a significantly longer PFS than those who received PD-1 inhibitor alone (n = 14, 5.0 vs. 3.0 months; P = 0.005). For patients with previously untreated wild-type NSCLC, the combination therapy in the first-line setting (n = 6) provided a marginally longer PFS than mono-chemotherapy (n = 6, 8.0 vs. 3.0 months; P = 0.075). For patients with relapsed NSCLC, the combination therapy in the ≥ second-line setting (n = 62) resulted in significantly higher objective response rate (19.3 vs. 5.0 vs. 2.4%; P = 0.013) and longer PFS (8.0 vs. 2.0 vs. 2.0 months; P <0.001) as compared to monotherapy of either chemotherapy (n = 41) or PD-1 inhibitor (n = 62). Anlotinib and PD-1 blockade combination therapy was an independent predictive factor of longer PFS (P <0.001). CONCLUSION: The combination of anlotinib and PD-1 inhibitor has promising efficacy and manageable toxicity as a second- or later-line treatment of relapsed NSCLC and possibly for relapsed SCLC.

Phase III Randomized Trial of Palonosetron and Dexamethasone With or Without Aprepitant to Prevent Nausea and Vomiting Induced by Full-dose Single-day Cisplatin-based Chemotherapy in Lung Cancer.

INTRODUCTION: This study aimed to determine the efficacy and safety of aprepitant, palonosetron, and dexamethasone to prevent chemotherapy-induced nausea and vomiting in patients with locally advanced or metastatic lung cancer receiving full-dose single-day cisplatin-based combination chemotherapy. MATERIALS AND METHODS: Patients diagnosed with locally advanced or metastatic lung cancer who received full dose single-day cisplatin-based chemotherapy were randomized (1:1) to aprepitant plus palonosetron and dexamethasone, or placebo plus palonosetron and dexamethasone. The primary endpoint was complete response of nausea and vomiting in the first cycle. The secondary endpoints were the proportion of patients with nausea and vomiting who received rescue antiemetic medication, the response of cross-over patients, and safety. RESULTS: A total of 244 patients were randomized. There was no difference between the 2 groups regarding personal characteristics. The administration of aprepitant significantly improved the complete response for vomiting in the overall period (92.6% vs. 79.93%; P < .01), but not a nausea-free response (75.4% vs. 71.3%; P > .05) in the first cycle. The percentage of patients who received rescue antiemetic medication was decreased for the aprepitant group (14.8% vs. 37.1%; P < .001). Patients who did not use aprepitant and suffered with nausea and vomiting in cycle 1 were crossed over to the aprepitant group (N = 32), and the rate of nausea and vomiting in cycle 2 was decreased to 37.5% (P < .05) and 25% (P < .05), respectively. There were no drug-related adverse effects. CONCLUSIONS: Aprepitant plus palonosetron and dexamethasone proved to be effective and well-tolerated in preventing chemotherapy-induced nausea and vomiting after administration of full-dose single-day cisplatin-based combination chemotherapy.
