| Hazard Information | Back Directory | [Usage]
It is a tight-binding, uncompetitive inhibitor of mitogen-activated protein kinase kinases (MEK) 1 and 2 currently in clinical development. | [Description]
Selumetinib (AZD6244; ARRY-142886) is an oral MEK inhibitor. In a randomized trial, NSCLC patients with wild-type KRAS were randomized to erlotinib
alone or combination therapy with selumetinib, while mutant KRAS patients were
randomized to selumetinib alone or combination therapy. The primary end points
were PFS for the KRAS wild-type cohort and objective response rate (ORR) for the
KRAS mutant cohort. Results were not impressive, with no PFS difference in the
KRAS wild-type arm (2.4 vs. 2.1?months) and no ORR difference in the KRASmutated subgroup (0% vs. 10%). A planned trial of selumetinib in combination
with the anti-PD-L1 antibody durvalumab has since been suspended (NCT03004105). | [Uses]

ChEBI: A member of the class of benzimidazoles that is 1-methyl-1H-benzimidazole which is substituted at positions 4, 5, and 6 by fluorine, (4-bromo-2-chlorophenyl)amino, and N-(2-hydroxyethoxy)aminocarbonyl groups, respectiv
ly. It is a MEK1 and MEK2 inhibitor. | [target]

| Questions And Answer | Back Directory | [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.
