ALK inhibitors are anti-cancer drugs that act on tumours with variations of anaplastic lymphoma kinase (ALK) such as an EML4-ALK translocation. [1] They fall under the category of tyrosine kinase inhibitors , which work by inhibiting proteins involved in the abnormal growth of tumour cells.
Ceritinib is an anaplastic lymphoma kinase (ALK) inhibitor primarily used for the treatment of ALK positive metastatic NSCLC. [8] [9] Previously, it was only indicated for patients who had developed resistant to crizotinib, another ALK inhibitor, but has since had its usage expanded to serve as a primary option for metastatic NSCLC.
Alectinib (INN [8]), sold under the brand name Alecensa, is an anticancer medication that is used to treat non-small-cell lung cancer (NSCLC). [6] [7] It blocks the activity of anaplastic lymphoma kinase (ALK). [9] [10] It is taken by mouth. [6] It was developed by Chugai Pharmaceutical Co. Japan, which is part of the Hoffmann-La Roche group.
In people affected by relapsed or refractory ALK+ anaplastic large cell lymphoma, crizotinib produced objective response rates ranging from 65% to 90% and 3 year progression free survival rates of 60–75%. No relapse of the lymphoma was ever observed after the initial 100 days of treatment. Treatment must be continued indefinitely at present.
Anaplastic lymphoma kinase (ALK) was originally discovered in 1994 [5] [7] in anaplastic large-cell lymphoma (ALCL) cells. ALCL is caused by a (2;5)(p23:q35) chromosomal translocation that generates the fusion protein NPM-ALK, in which the kinase domain of ALK is fused to the amino-terminal part of the nucleophosmin (NPM) protein.
Inhibitors of vascular endothelial growth factor (VEGF) [13] bevacizumab (Avastin) [14] [unreliable medical source?] Inhibitor of EML4-ALK. crizotinib shows benefit in a subset of non-small cell lung cancer that is characterized by the EML4-ALK fusion oncogene, [15] [16] found in some relatively young, never or light smokers with adenocarcinoma ...
The TALAPRO-2 results show how we continue innovating to improve survival for men with prostate cancer, which is the second most common cancer in men and the fifth most common cause of cancer ...
Entrectinib, sold under the brand name Rozlytrek, is an anti-cancer medication used to treat ROS1-positive non-small cell lung cancer and NTRK fusion-positive solid tumors. [5] It is a selective tyrosine kinase inhibitor (TKI), of the tropomyosin receptor kinases (TRK) A, B and C, C-ros oncogene 1 and anaplastic lymphoma kinase (ALK). [5]
