Usage

Description

Selumetinib, also known as AZD6244 and ARRY-142886, is an oral MEK inhibitor that functions as a tight-binding, uncompetitive inhibitor of mitogen-activated protein kinase kinases (MEK) 1 and 2. It is currently in clinical development and has been studied for its potential use in treating non-small cell lung cancer (NSCLC) patients with specific KRAS mutations.
Used in Pharmaceutical Industry:
Selumetinib is used as a potent MEK inhibitor for the treatment of non-small cell lung cancer (NSCLC) patients with specific KRAS mutations. It has been evaluated in clinical trials for its efficacy in combination with other therapies, such as erlotinib and the anti-PD-L1 antibody durvalumab, although some trials have been suspended due to unimpressive results. Selumetinib's role as a biomarker in human lung cancer cell research highlights its potential in advancing targeted cancer therapies.

Indications and Usage

Selumetinib, 1 has a chemical name of 5-[(4-Bromo-2-chlorophenyl)amino]-4-fluoro-N-(2-hydroxyethoxy)-1-methyl-1H-benzimidazole-6-carboxamide. It was developed by British company AstraZeneca and is used to treat advanced non-small cell lung cancer (NSCLC). It is mainly used to treat bile duct cancer, colon cancer, NSCLC, etc. Currently, Selumetinib is in stage III clinical trials for treatment of NSCLC.

Mechanisms of Action

Selumetinib is the first mitogenextracellular kinase (MEK1/2) inhibitor to be used in thyroid cancer clinical trials. It inhibits extracellular signal regulating kinase (ERK/2) and activates caspase to dramatically inhibit ERK1/2 phosphorylation.

Clinical Research

In phase II clinical trials of radioiodine-refractory papillary thyroid carcinoma, 39 patients took daily oral doses of Selumetinib (100mg bid) for 28 days; results showed that 21 patients’ conditions stabilized (54%), 11 patients’ conditions worsened (28%), 49% patients’ conditions were stable for 16 weeks, 36% patients’ conditions were stable for 24 weeks, and survival terms did not progress to 32 weeks. Negative reactions mainly consisted of rashes (59%), diarrhea (44%), and weakness (41%). Some studies found that after treating 20 patients with thyroid cancer with Selumetinib (75mg bid) for 4 weeks, Selumetinib increased the iodine uptake and retention of patients with radioiodine-refractory papillary thyroid carcinoma. In a blind and random comparative study between a Selumetinib and Docetaxel (DOC) combination treatment group and DOC and placebo treatment group for 87 mutant NSCLSC patients, survival times were 9.4 months and 5.2 months, PFS were 5.3 months and 2.1 months, RR were 37% and 0%, thus showing dramatic differences. Selumetinib’s main negative reactions include neutrophil depletion, dermatitis, and respiratory failure.
