Anaplastic lymphoma kinase (ALK) inhibitor crizotinib has dramatic effect in non-small cell lung cancer patients with ALK rearrangement. However, most patients eventually develop resistance. To discover therapeutic targets to overcome crizotinib resistance (CR), we generated patient-derived xenograft CR mice and subjected them to phosphorylation profiling, together with CR mice treated with ASP3026 or alectinib. We identified 100 proteins with different phosphorylation status in CR mice. Among them, AXL phosphorylation was increased in CR mice, which could not be reversed by ASP3026 or alectinib. Importantly, the combined treatment of crizotinib and AXL inhibitor in CR mice significantly inhibited tumor growth, compared to crizotinib alone. We also found that SHC1 phosphorylation was increased in CR mice and SHC1 knockdown sensitized ALK-driven cells to crizotinib. Our study provides a new view of signaling pathways leading to CR, suggesting AXL and SHC1 as potential targets for combination therapy to overcome CR.

Synaptic scaling is an extensively studied form of homeostatic plasticity critically involved in various brain functions. Although it is accepted that synaptic scaling is expressed through the postsynaptic accumulation of AMPA receptors (AMPARs), the induction mechanism remains elusive. In this study, we show that TTX treatment induces rapid but transient release of the neurite growth-promoting factor 2 (NGPF2), and this release is necessary and sufficient for TTX-induced scaling up. In addition, we show that inhibition of the anaplastic lymphoma kinase (ALK)-LIMK-cofilin signaling pathway blocks TTX- and NGPF2-induced synaptic scaling up. Furthermore, we show that TTX-induced release of NGPF2 is protein synthesis dependent and requires fragile X mental retardation protein 1 (FMRP1). These results indicate that activity blockade induces NGPF2 synthesis and release to trigger synaptic scaling up through LIMK-cofilin-dependent actin reorganization, spine enlargement, and stabilization of AMPARs at the synapse.

BACKGROUND AND OBJECTIVE:

Anaplastic lymphoma kinase gene rearrangements (ALKr) resulting in EML4-ALK proteins occur in a subset of solid tumors and are targeted by ALK inhibitors. Given the development of drug resistance to ALK inhibitors, ALK inhibitors with different kinase selectivity are required.

METHODS:

This phase I, non-randomized, open-label study evaluated the dose-limiting toxicity (DLT), safety, pharmacokinetics, and antitumor activity of ASP3026, a second-generation ALK inhibitor, in Japanese patients with solid tumors. Between 1 June 2011 and 20 January 2014, 29 patients received different daily doses of ASP3026 in the escalation (25 mg, n = 3; 50 mg, n = 3; 75 mg, n = 3; 125 mg, n = 4; 200 mg, n = 3; or 325 mg, n = 7) and expansion (200 mg, n = 6) cohorts.

RESULTS:

Three patients had DLTs at the 325-mg dose: cataract exacerbation, increased aspartate transaminase and alanine transaminase, and impaired hepatic function (all Grade 3 severity). Thus, the maximum tolerated dose was 200 mg. The treatment-emergent adverse event incidence was 100%; the most common events were nausea (n = 8, 27.6%), decreased appetite (n = 10, 34.5%), and fatigue (n = 9, 31.0%) of mild or moderate severity. Six patients were positive for ALK protein and three had ALKr. Two patients achieved partial responses: one with Ewing sarcoma (75-mg dose group) and one with an ALKr-positive inflammatory myofibroblastic tumor (125-mg dose group).

CONCLUSION:

ASP3026 at a 200-mg dose may provide therapeutic benefit for patients with solid tumors, with a tolerable safety profile.

CLINICAL TRIAL REGISTRATION:

This study is registered at ClinicalTrials.gov under the identifier NCT01401504 on July 25, 2011.
