Japan First to Approve Alectinib for ALK+ NSCLC

http://www.dddmag.com/news/2014/07/japan-first-approve-alectinib-alk-nsclc?et_cid=4034150&et_rid=523035093&type=headline

Roche announced that the Japanese Ministry of Health, Labor and Welfare (MHLW) has approved alectinib for the treatment of people living with non-small cell lung cancer (NSCLC) that is anaplastic lymphoma kinase fusion gene-positive (ALK+). The approval was based on results from a Japanese Phase 1/2 clinical study (AF-001JP) for people whose tumors were advanced, recurrent or could not be removed completely through surgery (unresectable).

Alectinib (also known as CH5424802,RO5424802), a second generation oral inhibitor of anaplastic lymphoma kinase (ALK), is being developed by Chugai and Roche for the treatment of patients with ALK-positive non-small cell lung cancer (NSCLC) that has progressed on Xalkori (Crizotinib).

Alectinib was discovered by Chugai Pharmaceutical Co. Ltd. Chugai became a subsidiary of Roche in 2002 and the Swiss group currently owns 59.9 percent of the company.

On October 8, 2013, Chugai Pharmaceutical announced that it has filed a new drug application to Japan’s Ministry of Health, Labour and Welfare (MHLW) for alectinib hydrochloride for the treatment of ALK fusion gene positive non-small cell lung cancer (NSCLC).

IT  is a potent and selective ALK inhibitor with IC50 of 1.9 nM.Alterations in the anaplastic lymphoma kinase (ALK) gene have been implicated in human cancers. Among these findings, the fusion gene comprising EML4 and ALK has been identified in non-small cell lung cancer (NSCLC) and fusion of ALK to NPM1 has been observed in anaplastic large cell lymphoma (ALCL). The possibility of targeting ALK in human cancer was advanced with the launch of crizotinib for NSCLC in the U.S. in 2011. The development of resistance to crizotinib in tumors, however, has led to the need for second-generation ALK inhibitors. One of these, alectinib hydrochloride, has been found to be an orally active, potent and highly selective ALK inhibitor with activity in ALK-driven tumor models. Alectinib has shown preclinical activity against cancers with ALK gene alterations, including NSCLC cells expressing the EML4-ALK fusion and ALCL cells expressing the NPM-ALK fusion. Alectinib was well tolerated and active in a phase I/II study conducted in Japan in patients with ALK-rearranged advanced NSCLC and in patients with ALK-positive NSCLC who had progressed on crizotinib. Alectinib has been submitted for approval in Japan for the treatment of ALK fusion gene-positive NSCLC and is in phase I/II development for ALK-rearranged NSCLC in the U.S.

(Preparation 30)
Compound F6-20

Under the same conditions as the synthesis of the compound B3-13-1, and the title compound was synthesized from compound F5-49.
1 H-NMR (400MHz, DMSO-D 6) δ: 12.70 (1H, s), 8.32 (1H, d, J = 7.9 Hz), 8.04 (1H, s), 8.00 (1H, s), 7.61 (1H , d, J = 8.5 Hz), 7.34 (1H, s), 3.64-3.57 (4H, m), 3.27-3.18 (2H, m), 2.82-2.66 (4H, m), 2.39-2.28 (1H, m ), 1.96-1.87 (2H, m), 1.76 (6H, s), 1.69-1.53 ​​(2H, m), 1.29 (3H, t, J = 7.3 Hz)
LCMS: m / z 483 [M + H] +
HPLC retention time: 1.98 minutes (analysis conditions U)

Hydrochloride 9 of compound F6-20 – ethyl-6, 6 – dimethyl-8 – (4 – morpholin-4 – yl – piperidin-1 – yl) -11 – oxo-6 ,11 – dihydro-5H-benzo [b I was dissolved at 60 ℃ in a mixture of 10 volumes of methyl ethyl ketone, 3 volumes of water and acetic acid volume 4-carbonitrile -] carbazol-3. I was dropped hydrochloric acid (2N) 1 volume of solution. After stirring for 30 minutes at 60 ℃, and the precipitated solid was filtered and added dropwise to 25 volume ethanol, 9 – Dry ethyl -6,6 – dimethyl-8 – (4 – morpholin-4 – yl – piperidin-1 – yl) I got a one-carbonitrile hydrochloride – 11 – oxo-6 ,11 – dihydro-5H-benzo [b] carbazol-3. Ethyl-6, 6 – 9 – obtained dimethyl-8 – (4 – morpholin-4 – yl – piperidin-1 – yl) -11 – oxo-6 ,11 – dihydro-5H-benzo [b] carbazol-3 – I was pulverized with a jet mill carbonitrile monohydrochloride.
1 H-NMR (400MHz, DMSO-D 6) δ: 12.78 (1H, s), 10.57 (1H, br.s), 8.30 (1H, J = 8.4 Hz), 8.05 (1H, s), 7.99 (1H , s), 7.59 (1H, d, J = 7.9 Hz), 7.36 (1H, s) ,4.02-3 .99 (2H, m) ,3.84-3 .78 (2H, m) ,3.51-3 .48 (2H, m), 3.15-3.13 (1H, s) ,2.83-2 .73 (2H, s) ,2.71-2 .67 (2H, s) ,2.23-2 .20 (2H, m) ,1.94-1 .83 (2H, m), 1.75 (6H, s ), 1.27 (3H, t, J = 7.5 Hz)
FABMS: m / z 483 [M + H] +

I was dissolved at 90 ℃ to 33 volume dimethylacetamide F6-20 F6-20 mesylate. Was added to 168 volumes mesylate solution (2 N) 1.2 volume, ethyl acetate solution was stirred for 4 hours. The filtered crystals were precipitated, and dried to obtain a F6-20 one mesylate. I was milled in a jet mill F6-20 one mesylate salt was obtained.
