CO-1686 is a novel, irreversible and orally delivered kinase inhibitor that specifically targets the mutant forms of EGFR including T790M(IC50=21 nM).

Background Information

An orally bioavailable irreversible EGFR inhibitor ......by AOBIOUS INC
Rociletinib, also known as CO-1686, is an irreversible tyrosine kinase inhibitor with a Ki of 21.5 nM for the EGFR L858R/T790M mutant and a Ki of 303.3 nM for wt EGFR. It inhibited the growth of non-small cell lung cancer (NSCLC) cells expressing mutant EGFR, and it induced apoptosis. It also demonstrated in vivo anti-tumor activity in mice bearing NSCLC tumors with activating EGFR mutations. Walter A.O., et al. "Discovery of a mutant-selective covalent inhibitor of EGFR that overcomes T790M-mediated resistance in NSCLC." Cancer Discov. 3: 1404-1415 (2013). The T790M mutation is the most common reason for acquired resistance to existing EGFR inhibitors in NSCLC. Rociletinib potently inhibited mutant EGFR L858R/T790M with an IC50 < 0.51nM. Rociletinib blocked the growth of T790M-positive NSCLC cells in vitro and in vivo. Walter A.O., et al. "CO-1686, a novel mutant-selective EGFR inhibitor, overcomes T790M mediated resistance in non-small cell lung cancer (NSCLC)." http://www.clovisoncology.com/assets/pdf/CO-1686/Clovis-Avila_AACR_2012_CO-1686_Poster_ClovisFINAL_27MAR12.pdf A phase I clinical trial in patients with EGFR mutated NSCLC demonstrated that rociletinib was well tolerated, and activity was observed in dose escalation cohorts. Sequist L.V., et al. "First-in-human evaluation of CO-1686, an irreversible, selective, and potent tyrosine kinase inhibitor of EGFR T790M." http://www.clovisoncology.com/files/CLVS_ASCO_2013_poster_CO1686_P1monotx_abstract2524.pdf ......by LC Laboratoies
CO-1686 is a novel, irreversible and orally delivered kinase inhibitor that specifically targets the mutant forms of EGFR including T790M(IC50=21 nM). IC50 Value: 21.5±1.7 nM (EGFRL858R/T790M); 303.3 ± 26.7 nM (EGFRWT) [1] in vitro: CO-1686 is a potent inhibitor of EGFR L858R/T790M kinase (kinact/Ki = (2.41 ± 0.30) x 105 M-1s-1) and is approximately 22-fold selective over WT EGFR (kinactt/Ki = (1.12 ± 0.14) x 104 M-1s-1). CO-1686 potently inhibited proliferation in the mutant-EGFR NSCLC cellswith GI50 values ranging from 7 - 32 nM. In comparison, the GI50 value for A431 cells, an epidermoid cell line that is driven by amplified WT EGFR(19), was 547 nM. Two cell lines expressing WT EGFR in the presence of an N- or KRAS mutation (NCI-H1299 and NCI-H358, respectively) were inhibited by CO-1686 at a concentration of 4275 and 1806 nM, respectively [1]. in vivo: CO-1686 displayed high oral bioavailability (65%) and a relatively long half-life of 2.6 hours when dosed at 20 mg/kg. Tumor-bearing mice were dosed orally once daily with CO-1686 as single agent and its effect on tumor growth was determined in several EGFR dependent xenograft models (Fig. 3A-C). Continuous oral dosing of CO-1686 causes dose-dependent and significant tumor growth inhibition in all EGFR-mutant models examined. At 100 mg/kg/day CO-1686 caused tumor regressions in two erlotinib-resistant models expressing the L858R/T790M EGFR mutation, the NCI-H1975 cell line xenograft and the patient-derived lung tumor xenograft (PDX) LUM1868, while erlotinib had no inhibitory effect on tumor growth [1].

Phase1/2 ......by MedChemexpress Co., Ltd.
CO-1686, also know as AVL-301, is an orally available small molecule, irreversible inhibitor of epidermal growth factor receptor (EGFR) with potential antineoplastic activity. EGFR inhibitor CO-1686 binds to and inhibits mutant forms of EGFR, including T790M, thereby leading to cell death of resistant tumor cells. Compared to other EGFR inhibitors, CO-1686 inhibits T790M, a secondary acquired resistance mutation, as well as other mutant EGFRs and may have therapeutic benefits in tumors with T790M-mediated resistance to other EGFR tyrosine kinase inhibitors. This agent shows minimal activity against wild-type EGFR, hence does not cause certain dose-limiting toxicities. Check for active clinical trials or closed clinical trials using this agent.

Cell Experiment

Cell lines NSCLC cell lines expressing mutant EGFR (HCC827, PC9, HCC827-EPR, and NCI-H1975) and cell lines expressing WT EGFR (A431, NCI-H1299, and NCI-H358)
Conditions ~10 μM; 72 hours
Method Cells are seeded at 3,000 cells per well in growth media supplemented with 5% FBS, 2 mmol/L, L-glutamine, and 1% penicillin–streptomycin, allowed to adhere overnight, and treated with a dilution series of test compounds for 72 hours. Cell viability is determined by CellTiter-Glo, and results are represented as background-subtracted relative light units normalized to a dimethyl sulfoxide (DMSO)–treated control. Growth inhibition (GI 50) values are determined by GraphPad Prism 5.04. MK-2206 and XL-880 compounds are obtained from Selleck Chemical. CI data are generated using CalcuSyn.
