Abstract
For non-small cell lung cancer patients with dual mutations in EGFR and ALK, there are currently no effective therapies. Consequently, novel EGFR/ALK dual-target inhibitors are urgently needed for the treatment of NSCLC. Here, we designed a series of highly effective small molecule dual inhibitors of ALK and EGFR. The biological evaluation highlighted that most of these new compounds could effectively inhibit both ALK and EGFR in enzymatic and cellular assays. Compound (+)-8l was investigated for its antitumor properties, and it was found that (+)-8l blocked the phosphorylation of EGFR and ALK induced by ligands and inhibited phosphorylation-ERK and phosphorylation-AKT induced by ligands. Furthermore, (+)-8l also induces apoptosis and G0/G1 cell cycle arrest in cancer cells and inhibits proliferation, migration, and invasion. Notably, (+)-8l significantly suppressed tumor growth in the H1975 cell-inoculated xenograft model (20 mg/kg/d, TGI: 96.11%), PC9 cell-inoculated xenograft model (20 mg/kg/d, TGI: 96.61%) and EML4 ALK-Baf3 cell-inoculated xenograft model (30 mg/kg/d, TGI: 80.86%). These results highlight the differentiated potential of (+)-8l to inhibit ALK rearrangement and EGFR mutation in NSCLC.

Abstract
The treatment of patients with advanced non-small cell lung cancer with anaplastic lymphoma kinase chromosomal rearrangements has been revolutionized by the development of tyrosine kinase inhibitors (TKIs). Excellent progress has been made over the past decade, with 4 TKIs now approved in the front-line setting. Alectinib is the preferred first-line option based on its efficacy and side-effect profile. The central nervous system (CNS) activity of alectinib and brigatinib has allowed for treatment of CNS metastases with TKI therapy. Once resistance inevitably develops, newer therapies such as lorlatinib can be considered.

Efficacy of Platinum/Pemetrexed Combination Chemotherapy in ALK-Positive NSCLC Refractory to Second-Generation ALK Inhibitors. J Thorac Oncol 2019; 15:258-265. [PMID: 31669591 DOI: 10.1016/j.jtho.2019.10.014] [Citation(s) in RCA: 48] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 09/14/2019] [Accepted: 10/12/2019] [Indexed: 12/17/2022]
Abstract
INTRODUCTION The current standard initial therapy for advanced ALK receptor tyrosine kinase (ALK)-positive NSCLC is a second-generation ALK tyrosine kinase inhibitor (TKI) such as alectinib. The optimal next-line therapy after failure of a second-generation ALK TKI remains to be established; however, standard options include the third-generation ALK TKI lorlatinib or platinum/pemetrexed-based chemotherapy. The efficacy of platinum/pemetrexed-based chemotherapy has not been evaluated in cases that are refractory to second-generation TKIs. METHODS This was a retrospective study performed at three institutions. Patients were eligible if they had advanced ALK-positive NSCLC refractory to one or more second-generation ALK TKI(s) and had received platinum/pemetrexed-based chemotherapy. RESULTS Among 58 patients eligible for this study, 37 had scans evaluable for response with measurable disease at baseline. The confirmed objective response rate to platinum/pemetrexed-based chemotherapy was 29.7% (11 of 37 patients; 95% confidence interval [CI]: 15.9% - 47.0%), with median duration of response of 6.4 months (95% CI: 1.6 months - not reached). The median progression-free survival for the entire cohort was 4.3 months (95% CI: 2.9 - 5.8 months). Progression-free survival was longer in patients who received platinum/pemetrexed in combination with an ALK TKI compared to those who received platinum/pemetrexed alone (6.8 months vs. 3.2 months, respectively; hazard ratio = 0.33; p = 0.025). CONCLUSIONS Platinum/pemetrexed-based chemotherapy shows modest efficacy in ALK-positive NSCLC after failure of second-generation ALK TKIs. The activity may be higher if administered with an ALK TKI, suggesting a potential role for continued ALK inhibition.
