Multicenter StudyA Phase II Study to Assess the Efficacy of Osimertinib in Patients With EGFR Mutation-positive NSCLC Who Developed Isolated CNS Progression (T790M-negative or Unknown) During First- or Second-generation EGFR-TKI or Systemic Disease Progression (T790M-negative) After Treatment With First- or Second-generation EGFR-TKI and Platinum-based Chemotherapy (WJOG12819L).
Osimertinib is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that has recently been established as a standard treatment option for chemotherapy-naive patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC). However, only about one-half of patients who have received prior treatment with a first- or second-generation EGFR-TKI are eligible for osimertinib therapy because its indication in the second-line setting is limited to metastatic NSCLC positive for the T790M resistance mutation of EGFR. ⋯ We have now designed a phase II study of osimertinib for patients with EGFR mutation-positive NSCLC who develop isolated central nervous system progression (T790M-negative or unknown) after first- or second-generation EGFR-TKI therapy (cohort 1) or who develop systemic disease progression (T790M-negative) after first- or second-generation EGFR-TKI therapy and platinum-based chemotherapy (cohort 2). A total of 70 patients (cohort 1, n = 17; cohort 2, n = 53) will be enrolled in this study, which originated from a suggestion of a dedicated network for patients with lung cancer in Japan.

Randomized Controlled Trial Multicenter StudyDesign and Rationale for a Phase III, Randomized, Placebo-controlled Trial of Durvalumab With or Without Tremelimumab After Concurrent Chemoradiotherapy for Patients With Limited-stage Small-cell Lung Cancer: The ADRIATIC Study.
Limited-stage (LS) small-cell lung cancer (SCLC) remains an area of high unmet medical need. The standard-of-care therapy comprises curative-intent platinum-based chemotherapy with concurrent radiotherapy (cCRT), which can be followed by prophylactic brain irradiation and then observation. However, most patients will relapse. ⋯ The primary endpoints are progression-free survival and overall survival. The secondary endpoints are overall survival and progression-free survival rates, objective response rate, and safety and tolerability. Recruitment began in September 2018.

Multicenter Study Observational StudyRelevance of Detection of Mechanisms of Resistance to ALK Inhibitors in ALK-Rearranged NSCLC in Routine Practice.
Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) have shown efficacy in the treatment of ALK-rearranged non-small-cell lung cancer (NSCLC), but the disease eventually progresses in all patients. In many cases, resistance to ALK TKIs arises through ALK mutations. Although clinical and biological data suggest variations in TKI efficacy according to the mechanism of resistance, ALK mutations are still rarely investigated in routine practice. ⋯ Targeted next-generation sequencing is suitable for detecting ALK resistance mutations in ALK-rearranged NSCLC patients in routine practice. It might help select the best treatment at the time of disease progression during treatment with an ALK TKI.

Multicenter Study Observational StudyCorrelations Between the Immune-related Adverse Events Spectrum and Efficacy of Anti-PD1 Immunotherapy in NSCLC Patients.
Immune-related adverse events (irAEs) developed during immunotherapy with anti-PD-1 agents, could be a predictive surrogate marker of clinical benefit in patients with advanced non-small-cell lung cancer (NSCLC). ⋯ Our study confirmed that irAEs are concordantly related to higher ORR, longer PFS, and longer OS with anti-PD-1 immunotherapy in patients with NSCLC.

Multicenter StudyEfficacy of Nivolumab and Pembrolizumab in Patients With Advanced Non-Small-Cell Lung Cancer Needing Treatment Interruption Because of Adverse Events: A Retrospective Multicenter Analysis.
The programmed death 1 antibodies (PD-1 Ab) nivolumab and pembrolizumab improve overall survival (OS) in advanced non-small-cell lung cancer (NSCLC). We evaluated the correlation between immune-related adverse events (irAE) and treatment interruption due to irAE on clinical efficacy of PD-1 Ab in advanced NSCLC. ⋯ Treatment interruption due to irAE was associated with a lower median OS compared to continuous PD-1 Ab therapy. Shorter OS seen with severe irAE might reflect the need for improved physician education in irAE treatment algorithms.
