| Hazard Information | Back Directory | [Description]
CO-1686 is an irreversible kinase inhibitor that specifically targets mutant forms of the epidermal growth factor receptor (EGFR) including T790M (Ki = 21.5 nM) with significantly reduced activity at the wild-type form of the receptor (Ki = 303.3 nM).1 CO-1686 has been shown to inhibit the proliferation of non-small cell lung cancer (NSCLC) cells expressing mutant EGFR with GI50 values ranging from 7-32 nM in vitro, inducing apoptosis.1 It also demonstrates anti-tumor activity in NSCLC EGFR mutant xenograft and transgenic models dosed orally at 100 mg/kg/day.1 | [Uses]
CO 1686 is seen as an irreversible epidermal growth factor receptor (EFGR1) kinase inhibitor. | [target]

On May 20, 2014, Clovis Oncology announced that the US FDA had granted its test drug CO-1686 for breakthrough treatment drug qualification, as a second line, single administrated drug for the treatment of EFGR mutation non-small cell lung cancer (NSCLC) of the T790M mutation patients. The awarding for this breakthrough therapeutic drug eligibility was based on the efficacy and safety results of Co-1686 in an ongoing Phase 1/2 study. Data of related study have shown that CO-1686 is a third-generation EGFR inhibitor, being used for the treatment of non-small cell lung cancer, overcoming the drug resistance generated from the EGFR T790M mutations, and has excellent efficacy and tolerability on NSCLC with T790M + EGFR mutations. Its major market competitor, the third-generation EGFR inhibitor, AZD9291 (AstraZeneca) has also gained FDA's groundbreaking drug eligibility.
CO-1686 is a novel, oral-administrated, targeted covalent (irreversible) inhibitor of the epidermal growth factor receptor (EGFR) mutations, being able to suppress key activation mutations and T790 drug-resistant mutations, leaving the wild-type EGFR signal unused. This drug was developed for the treatment of NSCLC patients carrying initially activated EGFR mutations and major resistant mutant T790M.

Rociletinib (CO-1686, AVL-301) is an irreversible, mutation-selective EGFR inhibitor that targets EGFRL858R/T790M and EGFRWT with a Ki of 21.5 nM and 303.3 nM, respectively. Phase 2.
Target: EGFR (L858R/T790M) EGFR (wt)
IC50: 21.5 nM (Ki) 303.3 nM (Ki) | [In vitro study]
CO-1686 inhibited the p-EGFR in EGFR-expressing cells with an IC50 ranging from 62 to 187 nM while inhibiting EGFR phosphorylation. In three WT EGFR-expressing cells, the IC50 is larger than 2,000 nM. CO-1686 can selectively inhibit the growth of mutant EGFR expressing NSCLC cells with a GI50 ranging from 7 to 32 nM while inducing apoptosis. The CO-1686-resistant NSCLC cell line exhibited a signal for epithelial-mesenchymal transition and increased susceptibility to AKT inhibitors. | [In vivo studies]
In all EGFR mutant models, as well as in transgenic mice expressing human EGFRL858R-and EGFRL858R/T790M, CO-1686 caused significant tumor growth inhibition in a dose-dependent manner. | [Synthesis method]
5-fluoro-2-nitroanisole was condensed with piperazine, acetylated and reduced to give 1-(3-methoxy-4-aminophenyl)-4-acetylpiperazine (4) In addition, use 2, 4-dichloro-5-trifluoro methyl pyrimidine to undergo condensation with 3-nitroaniline, reduction and amidation to obtain N-[3-(2-Chloro-5-trifluoromethyl-pyrimidin-4-amino) phenyl] acrylamide (7). 4 and 7 were condensed to give the EGFR inhibitor, the anticancer drug CO-1686 with a total yield of about 71% (based on 2, 4-dichloro-5-trifluoromethyl pyrimidine).
