RESUMO

We studied the effect of food on pharmacokinetics, safety, and tolerability of BMS-690514. Two open-label, randomized, single-dose, 2-treatment, 2-period crossover studies were performed in healthy subjects. In study 1 (N = 26), a single oral dose of BMS-690514, 200 mg, was administered while fasting or after a high-fat meal, and in study 2 (N = 17), a single oral dose of BMS-690514, 200 mg, was administered while fasting or after a light meal. Compared with fasting, the adjusted geometric mean maximum observed plasma concentration (C(max)), area under the plasma concentration-time curve from time zero to time of last quantifiable concentration (AUC(0-T)), area under the plasma concentration-time curve from time zero extrapolated to infinite time (AUC(INF)) of BMS-690514 increased by 55%, 33%, and 34%, respectively, following a high-fat meal (951 kcal, 52% fat) and by 41%, 20%, and 20%, respectively, following a light meal (336 kcal, 75% carbohydrate). BMS-690514 was well tolerated in both studies. Most frequently occurring adverse events were diarrhea and acne in study 1 and rash, dry skin, and diarrhea in study 2. Systemic exposure of highly soluble BMS-690514 was increased when given along with a meal, probably through inhibition of intestinal first-pass metabolism and/or efflux transporters by food. These studies also demonstrated a tolerable safety profile of BMS-690514 in the absence and presence of food.

RESUMO

Substituted 3-((2-(pyridin-2-ylamino)thiazol-5-ylmethyl)amino)benzamides were identified as potent and selective inhibitors of vascular endothelial growth factor receptor-2 (VEGFR-2) kinase activity. The enzyme kinetics associated with the VEGFR-2 inhibition of 14 (Ki=49+/-9 nM) confirmed that the aminothiazole-based analogues are competitive with ATP. Analogue 14 demonstrated excellent kinase selectivity, favorable pharmacokinetic properties in multiple species, and robust in vivo efficacy in human lung and colon carcinoma xenograft models.
