Brigatinib (AP-26113, Alunbrig) is a second-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) that is highly active in non-small cell lung cancer (NSCLC) harboring ALK translocation. Brigatinib was found to be very active against different ALK resistance mutations that mediate acquired resistance biology processes, particularly G1269A ALK C1156Y, I1171S/T, V1180L and others. Different clinical trials evaluated the activity of brigatinib in crizotinib-resistant patients, confirming high activity with durable response not only in parenchymal disease, but also in intracranial disease...

In the last decade, there have been major therapeutic advances in the management of patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer. Crizotinib was the first approved ALK inhibitor with significant benefits over chemotherapy. However, patients inevitably develop disease progression especially in central nervous system and acquire resistance to crizotinib. Several next-generation ALK inhibitors have been developed to overcome these resistance mechanisms and have demonstrated clinical benefits in crizotinib-refractory non-small cell lung cancer including in central nervous system...

Brigatinib is the second-generation anaplastic lymphoma kinase - inhibitor in non-small cell lung cancer and it can overcome the crizotinib-resistance. Chromatographic separation was carried out on an Acquity Ultra Performance Liquid Chromatography (UPLC) unit with a BEH C18 column (2.1mm×50mm, 1.7μm). The mobile phase was composed of acetonitrile and 0.1% formic acid in water. No endogenous interfering compounds was discovered at retention time of brigatinib (0.56min) and imatinib (IS, 1.41min). MS/MS detection was performed in positive mode...

Tumorigenic rearrangements in anaplastic lymphoma kinase (ALK) account for 3-7% of all non-small cell lung cancers (NSCLC). Treatment with targeted tyrosine kinase inhibitors (TKIs) has shown impressive clinical responses. Crizotinib was the first agent approved for front-line therapy of ALK-rearranged NSCLC after it demonstrated superiority to chemotherapy in response rate, duration of response, and progression-free survival. However, eventually all patients progress on crizotinib therapy, with the central nervous system (CNS) being the most common site, which served as the impetus for the development of more potent next-generation ALK inhibitors...

Patients with lung cancer who show EML4-ALK translocation are routinely treated with ALK tyrosine kinase inhibitors, although in the majority of cases, these patients develop resistance over time. The central nervous system is a common of site of recurrence in this population, which calls for next-generation drugs that can penetrate into the brain and achieve clinically meaningful central nervous system activity. Here, I report the case of a female patient diagnosed with adenocarcinoma of the lung in 2005, at the age of 46 years, who underwent lobectomy and then experienced a series of progression episodes 6 years later...

Brigatinib (ALUNBRIG™) is a small molecule antineoplastic anaplastic lymphoma kinase (ALK) inhibitor being developed by ARIAD Pharmaceuticals (a wholly-owned subsidiary of Takeda Pharmaceutical Company). In April 2017 brigatinib received accelerated approval in the USA for the treatment of patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to crizotinib. The development of resistance to crizotinib is a therapeutic challenge that has led to the development of second-generation ALK-inhibitors such as brigatinib, which have activity against treatment-resistant ALK mutants...

The FDA has approved the ALK inhibitor brigatinib for patients with metastatic non-small cell lung cancer who cannot take crizotinib or whose disease worsened despite its use. The decision was based upon results of a phase II study that assessed two drug doses, with overall response rates of 45% and 56% respectively. The drug's effect on overall survival remains unclear, as does the optimal sequence of brigatinib and the three other ALK inhibitors.

Purpose Most crizotinib-treated patients with anaplastic lymphoma kinase gene ( ALK)-rearranged non-small-cell lung cancer (ALK-positive NSCLC) eventually experience disease progression. We evaluated two regimens of brigatinib, an investigational next-generation ALK inhibitor, in crizotinib-refractory ALK-positive NSCLC. Patients and Methods Patients were stratified by brain metastases and best response to crizotinib. They were randomly assigned (1:1) to oral brigatinib 90 mg once daily (arm A) or 180 mg once daily with a 7-day lead-in at 90 mg (180 mg once daily [with lead-in]; arm B)...

Brigatinib (AP26113) is a dimethylphosphine oxide group-containing tyrosine kinase inhibitor (TKI) constructed around a bisanilinopyrimidine scaffold with potent activity against the anaplastic lymphoma kinase (ALK) and several other targets. Despite the activity of first- and second-generation ALK inhibitors in advanced ALK-rearranged lung cancers, the development of acquired resistance represents an ongoing challenge. Later generation ALK inhibitors such as brigatinib are important potential tools in the management of patients with acquired resistance characterized by continued dependency on ALK...

The discovery of anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC) in 2007 led to the development and subsequent approval of the ALK inhibitor crizotinib in 2011. However, despite its clinical efficacy, resistance to crizotinib invariably develops. There is now a next generation of ALK inhibitors, including two that have been approved-ceritinib and alectinib-and others that are in development-brigatinib, lorlatinib and X-396. Ceritinib and the other next-generation ALK inhibitors are more potent than crizotinib and can overcome tumor cell resistance mechanisms...

Osimertinib has been demonstrated to overcome the epidermal growth factor receptor (EGFR)-T790M, the most relevant acquired resistance to first-generation EGFR-tyrosine kinase inhibitors (EGFR-TKIs). However, the C797S mutation, which impairs the covalent binding between the cysteine residue at position 797 of EGFR and osimertinib, induces resistance to osimertinib. Currently, there are no effective therapeutic strategies to overcome the C797S/T790M/activating-mutation (triple-mutation)-mediated EGFR-TKI resistance...

Results from a phase I/II trial indicate that the investigational ALK inhibitor brigatinib is active in patients with ALK-rearranged non-small cell lung cancer. Patients who had previously received crizotinib-as well as those who hadn't-responded to the drug, which was also active in patients with brain metastases.

BACKGROUND: Anaplastic lymphoma kinase (ALK) gene rearrangements are oncogenic drivers of non-small-cell lung cancer (NSCLC). Brigatinib (AP26113) is an investigational ALK inhibitor with potent preclinical activity against ALK mutants resistant to crizotinib and other ALK inhibitors. We aimed to assess brigatinib in patients with advanced malignancies, particularly ALK-rearranged NSCLC. METHODS: In this ongoing, single-arm, open-label, phase 1/2 trial, we recruited patients from nine academic hospitals or cancer centres in the USA and Spain...

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...

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...

Crizotinib is an oral inhibitor of anaplastic lymphoma kinase (ALK) with remarkable clinical activity in patients suffering from ALK-rearranged non-small cell lung cancer (NSCLC), accounting to its superiority compared to chemotherapy. Unfortunately, virtually all ALK-rearranged tumors acquire resistance to crizotinib, frequently within one year since the treatment initiation. To date, therapeutic strategies to overcome crizotinib resistance have focused on the use of more potent and structurally different compounds...
