Ceritinib is a second-generation selective and potent oral anaplastic lymphoma kinase (ALK) inhibitor approved for ALK-positive advanced non-small cell lung cancer previously treated with crizotinib. Population pharmacokinetic (PK) analysis was performed to describe the PK of ceritinib and was used to evaluate the covariate effects on systemic exposure at its label dose (750 mg orally once daily). Ceritinib concentration-time data from 4 clinical studies were described by a 1-compartment model with delayed first-order absorption and time-dependent elimination...

The piperidine fragment in ceritinib was replaced with diverse aliphatic amines to improve inherent resistance issues of ceritinib. While most of the prepared compounds exhibit as similar in vitro activities as ceritinib, compound 10 shows encouraging activities against wild-type ALK as well as crizotinib-resistant mutants including extremely resistant G1202R mutant with an IC50 of 1.8 nM. Furthermore, pharmacokinetic profiles of 10 is apparently better than that of ceritinib. In murine xenograft studies, compound 10 turns out to be as active as ceritinib, suggesting that further optimization of 10 may lead to clinical candidates overcoming ALK mutant issues...

Anaplastic lymphoma kinase (ALK) gene rearrangements occur in a small portion of patients with non-small cell lung cancer (NSCLC). These gene rearrangements lead to constitutive activation of the ALK kinase and subsequent ALK-driven tumor formation. Patients with tumors harboring such rearrangements are highly sensitive to ALK inhibitors, such as crizotinib, ceritinib, and alectinib. Resistance to these kinase inhibitors occurs through several mechanisms, resulting in ongoing clinical challenges. This review summarizes the biology of ALK-positive lung cancer, methods for diagnosing ALK-positive NSCLC, current FDA-approved ALK inhibitors, mechanisms of resistance to ALK inhibition, and potential strategies to combat resistance...

Anaplastic lymphoma kinase (ALK) gene rearrangement was reported in 3-7% of primary non-small-cell lung cancer (NSCLC) and its presence is commonly associated with adenocarcinoma (AD) type and non-smoking history. ALK tyrosine kinase inhibitors (TKIs) such as crizotinib, alectinib and ceritinib showed efficiency in patients with primary NSCLC harboring ALK gene rearrangement. Moreover, response to ALK TKIs was observed in central nervous system (CNS) metastatic lesions of NSCLC. However, there are no reports concerning the frequency of ALK rearrangement in CNS metastases...

In 2007, the rearrangement of anaplastic lymphoma kinase (ALK) was identified to be associated with the pathogenesis of a subset of patients with non-small-cell lung cancer (NSCLC). Surprisingly, approximately 4 years after the discovery of ALK rearrangement in lung cancer, the first-in-class ALK inhibitor (ALKi), crizotinib, was approved for metastatic ALK-rearranged NSCLC by the US Food and Drug Administration. Subsequently, next-generation ALKis, such as alectinib and ceritinib, have been developed, and some of them have been applied in the clinical setting...

We examined an immediate, but short-lived, response to crizotinib, a drug with a new indication for ROS1 rearranged non-small cell lung cancer (NSCLC) in a middle-aged non-smoker. The patient presented with metastatic NSCLC and extensive disease in multiple organs. He was treated with crizotinib 250 mg twice a day. Within 2-3 days, his condition rapidly improved, which was evident in a CT scan 2 months later. However, after 3 months of treatment, his condition deteriorated dramatically. The patient did not respond to ceritinib, a second-line drug that targets anaplastic lymphoma kinase, and died shortly after...

Crizotinib, a first-generation anaplastic lymphoma kinase (ALK) tyrosine-kinase inhibitor, is known to be effective against echinoderm microtubule-associated protein-like 4 (EML4)-ALK-positive non-small cell lung cancers. Nonetheless, the tumors subsequently become resistant to crizotinib and recur in almost every case. The mechanism of the acquired resistance needs to be deciphered. In this study, we established crizotinib-resistant cells (A925LPE3-CR) via long-term administration of crizotinib to a mouse model of pleural carcinomatous effusions; this model involved implantation of the A925LPE3 cell line, which harbors the EML4-ALK gene rearrangement...

PURPOSE: Non-small cell lung cancers (NSCLCs) harboring ALK gene rearrangements (ALK(+)) typically become resistant to the first-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) crizotinib through development of secondary resistance mutations in ALK or disease progression in the brain. Mutations that confer resistance to second-generation ALK TKIs ceritinib and alectinib have also been identified. Here, we report the structure and first comprehensive preclinical evaluation of the next-generation ALK TKI brigatinib...

Many oncologists have already adopted ceritinib as a second-line treatment for ALK-positive non-small cell lung cancer in patients who have developed resistance to crizotinib. The results of a randomized trial, presented at the European Society for Medical Oncology 2016 Congress, confirm that ceritinib is an effective option because it increases progression-free survival by 4 months over chemotherapy.

Anaplastic lymphoma kinase (ALK) has become as an important target for the treatment of various human cancers, especially non-small-cell lung cancer. A mutation, F1174C, suited in the C-terminal helix αC of ALK and distal from the small-molecule inhibitor ceritinib bound to the ATP-binding site, causes the emergence of drug resistance to ceritinib. However, the detailed mechanism for the allosteric effect of F1174C resistance mutation to ceritinib remains unclear. Here, molecular dynamics (MD) simulations and binding free energy calculations [Molecular Mechanics/Generalized Born Surface Area (MM/GBSA)] were carried out to explore the advent of drug resistance mutation in ALK...

BACKGROUND: Clinical outcomes of anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancer according to ALK fusion variants are not clear. We aimed to investigate the prevalence of ALK fusion variants and to compare clinical outcomes according to ALK fusion variants. METHODS: A retrospective analysis was conducted on patients with advanced ALK-rearranged adenocarcinoma treated with chemotherapy and ALK inhibitors. ALK rearrangement was identified by fluorescence in situ hybridization and confirmed by immunohistochemistry...

The identification of anaplastic lymphoma kinase (ALK) gene rearrangements in subsets of non-small cell lung cancer patients has provided with unparalleled opportunities to hinder the progression of this disease through targeting the activity of these specific molecules. Unfortunately most patients develop disease progression in less than a year of treatment with crizotinib, the first-generation ALK-inhibitor. Areas covered: We review the resistance mechanisms to ALK inhibitors as well as an overview of the clinical activity of the alectinib, a second generation ALK inhibitor...

BACKGROUND: Inflammatory myofibroblastic tumors (IMTs) are rare sarcomas that can occur at any age. Surgical resection is the primary treatment for patients with localized disease; however, these tumors frequently recur. Less commonly, patients with IMTs develop or present with metastatic disease. There is no standard of care for these patients and traditional cytotoxic therapy is largely ineffective. Most IMTs are associated with oncogenic ALK, ROS1 or PDGFRβ fusions and may benefit from targeted therapy...

: Activation of the epidermal growth factor receptor (EGFR) pathway is one of the mechanisms inducing acquired resistance to anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) such as crizotinib and alectinib. Ceritinib is a highly selective ALK inhibitor and shows promising efficacy in non-small cell lung cancers (NSCLCs) harboring the ALK gene rearrangement. However, the precise mechanism underlying acquired resistance to ceritinib is not well defined. This study set out to clarify the mechanism in ALK-translocated lung cancer and to find the preclinical rationale overcoming EGFR pathway-induced acquired resistance to ALK-TKIs...

Ceritinib (Zykadia™) is an oral, selective inhibitor of the anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase which, after genetic rearrangement, acts as an oncogenic driver in a proportion of non-small cell lung cancers (NSCLCs). The drug is approved in several countries worldwide for the treatment of patients with ALK-positive, advanced NSCLC who have previously received the first-generation ALK inhibitor crizotinib (indication details may vary by country). Approval was based on its clinical benefit in this setting in the phase I and II trials known as ASCEND-1 and -2...

Patients are diagnosed as anaplastic lymphoma kinase (ALK) positive, i.e. exhibiting the ALK rearrangement, and comprise 3-7% of non-small-cell lung cancer (NSCLC) cases. Three generations of ALK inhibitors have been developed and used in targeted therapy, although there are still improving spaces of drug resistance at the initiation of each treatment. The current review discusses the pathophysiology of ALK-positive NSCLC and the role of three generations of ALK target inhibitors including crizotinib, ceritinib, alectinib and lorlatinib, as well as the mechanisms of the secondary resistance...

The treatment of patients with ALK-rearranged non-small-cell lung cancer was completely revolutionized by the introduction of Crizotinib, a small molecule inhibiting ALK, MET and ROS1. Given that resistance occurs within approximately 12 months, in order to develop more potent inhibitors and to increase drug penetration to CNS, innovative ALK-inhibitors were developed. Second-generation ALK inhibitors Ceritinib (LDK378), Alectinib (CH5424802/RO5424802) and Brigatinib (AP26113) have shown significant clinical activity, and were rapidly approved by regulatory agencies...

Anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancers (NSCLC) account for 3% to 7% of all NSCLC and require a standard treatment by crizotinib. However, crizotinib resistance is frequent within the first 12 months of treatment. Ceritinib is a novel tyrosine kinase inhibitor of ALK recently introduced in France for metastatic or locally advanced crizotinib-resistant ALK NSCLC. We report the first use of ceritinib in our institution with a spectacular tumoral response after only 3 months of treatment...

Anaplastic lymphoma kinase (ALK) plays a crucial role in multiple malignant cancers. It is known as a well-established target for the treatment of ALK-dependent cancers. Even though substantial efforts have been made to develop ALK inhibitors, only crizotinib, ceritinib, and alectinib had been approved by the U.S. Food and Drug Administration for patients with ALK-positive non-small cell lung cancer (NSCLC). The secondary mutations with drug-resistance bring up difficulties to develop effective drugs for ALK-positive cancers...
