CEP-32496

SKU: orb1226849

Description

CEP-32496 is a highly potent inhibitor of BRAF(V600E/WT) and c-Raf with Kd of 14 nM/36 nM and 39 nM, also potent to Abl-1, c-Kit, Ret, PDGFRβ and VEGFR2, respectively; insignificant affinity for MEK-1, MEK-2, ERK-1 and ERK-2. Phase 1/2.(In Vitro):Agerafenib (CEP-32496) exhibits high potency against several BRAFV600E-dependent cell lines and selective cytotoxicity for tumor cell lines expressing mutant BRAFV600E versus those containing wild-type BRAF. Agerafenib exhibits potent binding (BRAFV600E Kd=14 nM) and cellular activity (pMEK IC50=82 nM and A375 proliferation IC50=78 nM), with activity in the proliferation assay. Agerafenib also exhibits a favorable CYP450 inhibition profile, with measured IC50 values greater than 10 μM versus the CYP1A2, CYP2C9, CYP2D6, and CYP3A4 isoforms and an IC50=3.4 μM versus CYP2C19.\n(In Vivo):Oral administration of Agerafenib (CEP-32496) to Colo-205 tumor xenograft-bearing mice results in significant inhibition of pMEK in tumor cell lysates. For instance, a single 30 mg/kg (po) dose of Agerafenib leads to a 50 and 75% inhibition of normalized pMEK in tumor lysates at the 2 and 6 h postdose time point, respectively (p<0.03), while a 55 mg/kg (po) dose resulted in a 75% to 57% (p<0.03) inhibition of pMEK at 2 through 10 h post administration, with normalization to baseline by 24 h. Agerafenib exhibits an exceptional PK profile in mouse, dog, and cynomolgus monkey. Administration of Agerafenib to beagle dogs (single dose of 1 mg/kg iv and 10 mg/kg po) results in low clearance (CL=5.0 (mL/min)/kg) and excellent bioavailability (%F=100). Similarly, in cynomolgus monkey, the administration of Agerafenib (single dose of 1 mg/kg iv and 10 mg/kg po) leads to high oral exposure due to low clearance (CL=6.7 mL/min/kg) and excellent bioavailability (%F=100).
