PURPOSE Brigatinib, a next-generation anaplastic lymphoma kinase (ALK) inhibitor, demonstrated superior progression-free survival (PFS) and improved health-related quality of life (QoL) versus crizotinib in advanced ALK inhibitor–naive ALK-positive non–small cell lung cancer (NSCLC) at first interim analysis (99 events; median brigatinib follow-up, 11.0 months) in the open-label, phase III ALTA-1L trial (ClinicalTrials.gov identifier: NCT02737501 ). We report results of the second prespecified interim analysis (150 events). METHODS Patients with ALK inhibitor–naive advanced ALK-positive NSCLC were randomly assigned 1:1 to brigatinib 180 mg once daily (7-day lead-in at 90 mg once daily) or crizotinib 250 mg twice daily. The primary end point was PFS as assessed by blinded independent review committee (BIRC). Investigator-assessed efficacy, blood samples for pharmacokinetic assessments, and patient-reported outcomes were also collected. RESULTS Two hundred seventy-five patients were randomly assigned (brigatinib, n = 137; crizotinib, n = 138). With median follow-up of 24.9 months for brigatinib (150 PFS events), brigatinib showed consistent superiority in BIRC-assessed PFS versus crizotinib (hazard ratio [HR], 0.49 [95% CI, 0.35 to 0.68]; log-rank P < .0001; median, 24.0 v 11.0 months). Investigator-assessed PFS HR was 0.43 (95% CI, 0.31 to 0.61; median, 29.4 v 9.2 months). No new safety concerns emerged. Brigatinib delayed median time to worsening of global health status/QoL scores compared with crizotinib (HR, 0.70 [95% CI, 0.49 to 1.00]; log-rank P = .049). Brigatinib daily area under the plasma concentration–time curve was not a predictor of PFS (HR, 1.005 [95% CI, 0.98 to 1.031]; P = .69). CONCLUSION Brigatinib represents a once-daily ALK inhibitor with superior efficacy, tolerability, and QoL over crizotinib, making it a promising first-line treatment of ALK-positive NSCLC.

Purpose Alectinib is an anaplastic lymphoma kinase (ALK) –specific kinase inhibitor that seems to be effective against non–small-cell lung cancer (NSCLC) with a variety of ALK mutations. The primary analysis of AF-001JP reported a promising overall response rate. To assess progression-free survival (PFS) and overall survival (OS), patients from the phase II part of AF-001JP were followed up for approximately 3 years. Patients and Methods Oral alectinib 300 mg was administered twice per day to patients with ALK inhibitor–naïve, ALK-positive NSCLC who had progressed after one or more regimens of previous chemotherapy. In this long-term follow-up, efficacy (PFS, OS), correlation between tumor shrinkage and PFS, safety of alectinib, and relief of cancer symptoms were evaluated. Results At the updated data cutoff (September 10, 2015; first patient in August 30, 2011, last patient in April 18, 2012), 25 of 46 phase II patients were still receiving alectinib. Disease progression was confirmed in 18 patients (39%); median PFS was not reached (3-year PFS rate, 62%; 95% CI, 45 to 75). Fourteen patients had brain metastases at baseline; of these, 6 remained in the study without CNS and systemic progression. Tumor shrinkage and PFS showed no correlation. The 3-year OS rate was 78% (13 events). The most common treatment-related adverse event (all grades) was increased blood bilirubin (36.2%). Most cancer symptoms were relieved early, and medication for symptoms was dramatically decreased during alectinib therapy. Conclusion Alectinib was effective in this 3-year follow-up with a favorable safety profile over a long administration period in ALK-positive NSCLC without previous ALK inhibitor treatment.

PURPOSE: In our previous phase II study, the cisplatin, gemcitabine, and vinorelbine (PGV) regimen produced a median survival time (MST) of approximately 1 year in advanced non–small-cell lung cancer (NSCLC) patients. The present study was aimed at comparing the MST of patients treated with this triplet regimen with the MSTs of patients receiving cisplatin and vinorelbine (PV) or cisplatin and gemcitabine (PG). PATIENTS AND METHODS: From April 1997, patients with locally advanced or metastatic NSCLC, an age of ≤ 70 years, and an Eastern Cooperative Oncology Group performance status ≤ 1 were randomized to receive one of the following regimens: cisplatin 50 mg/m2, gemcitabine 1,000 mg/m2, and vinorelbine 25 mg/m2 on days 1 and 8 every 3 weeks (arm A); cisplatin 100 mg/m2 on day 1 and gemcitabine 1,000 mg/m2 on days 1, 8, and 15 every 4 weeks (arm B); or cisplatin 120 mg/m2 on days 1 and 29 and vinorelbine 30 mg/m2/wk (arm C). According to the two-stage design for phase III trials, an interim analysis was planned when the first 60 patients per arm were assessable for survival. RESULTS: The survival data of 180 NSCLC patients (stage IIIB, 76 patients; stage IV, 104 patients) were analyzed in April 1999. Overall, 128 patients had died (PGV, n = 33; PG, n = 42; and PV, n = 53). The MST of patients in the PGV, PG, and PV arms was 51, 42, and 35 weeks, respectively, and the corresponding 1-year projected survival rates were 45%, 40%, and 34%, respectively. When only patients with stage IV disease were considered, an even stronger difference was seen between PGV (MST = 47 weeks) and both PG (34 weeks) and PV (27 weeks). At multivariate Cox analysis, the estimate hazard of death for patients receiving PGV compared with those receiving PV was 0.35 (95% confidence interval, 0.16 to 0.77; P < .01). The response rates were 47% in the PGV arm, 30% in the PG arm, 25% in the PV arm. Both hematologic and nonhematologic toxicities were not substantially worse in patients who received the PGV regimen. CONCLUSION: The PGV regimen is associated with a substantial survival gain (MST > 3 months longer) when compared with the PV combination. Because this difference in survival met one of the early stopping rules, the accrual in the PV arm has been stopped (null hypothesis rejected). Enrollment still continues in the PGV and PG arm to ascertain whether the PGV regimen can also produce a significantly longer survival than that obtained with the PG regimen.

e20542 Background: Anaplastic lymphoma kinase (ALK) inhibitors show high clinical efficacy in patients with ALK-positive advanced non-small cell lung cancer (NSCLC). However, the long-term clinical outcomes remain unknown. Methods: We retrospectively reviewed medical records of patients with ALK inhibitor-naïve ALK-positive advanced NSCLC who initiated alectinib or crizotinib therapy at the Shizuoka Cancer Center between June 2010 and December 2011. Results: This retrospective study included 14 patients (male/female, 5/9; PS 0/1, 6/8; adenocarcinoma/adenosquamous carcinoma, 13/1; smoker/never smoker, 8/6; brain metastasis presence/absence, 5/9; number of prior chemotherapy regimens 0/1/≥2, 1/7/6; alectinib/crizotinib, 4/10) with a median age of 55 years (range, 28-71). At the data cut-off (January 16, 2017), three patients were still receiving first ALK inhibitors (alectinib in two patients and crizotinib in one). One patient requested the discontinuation of alectinib therapy after five years. One patient discontinued crizotinib therapy due to unacceptable toxicity. Nine patients discontinued first ALK inhibitors due to disease progression. The overall response rate was 78.6% with complete response in two patients (14.3%), partial response in nine (64.3%), stable disease in one (7.1%), and progressive disease in two (14.3%). The median progression-free survival (PFS) for all 14 patients was 15.3 months, and the five-year PFS rate was 35.7%. The five-year PFS rates in patients treated with alectinib and crizotinib were 75.0% and 20.0%, respectively. The median overall survival (OS) for all 14 patients was 36.8 months, and the five-year OS rate was 42.9%. The five-year OS rates in patients treated with alectinib and crizotinib were 75.0% and 30.0%, respectively. Conclusions: ALK inhibitors showed favorable long-term clinical outcomes in patients with ALK inhibitor-naïve ALK-positive advanced NSCLC, especially in patients treated with alectinib.
