AIMS: Macrophage recruitment through C-C motif chemokine receptor-2 (CCR2) into adipose tissue is believed to play a role in the development of insulin resistance and type 2 diabetes mellitus (T2DM). The objective of this Phase 2 proof-of-concept study was to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of JNJ-41443532, an orally bioavailable CCR2 antagonist, in patients with T2DM.
METHODS: This was a 4-week, double-blind, placebo-controlled, randomized, multicenter study. A total of 89 patients were randomized to receive either 250- or 1000-mg of JNJ-41443532 twice daily, 30-mg of pioglitazone once daily (reference arm), or placebo. The primary endpoint was change from baseline in 23-h weighted mean glucose (WMG); secondary endpoints included change from baseline in fasting plasma glucose (FPG), insulin resistance (Homeostatic Model Assessment [HOMA-IR]), insulin secretion (HOMA-%B) and body weight.
RESULTS: Absorption of JNJ-41443532 into the systemic circulation occurred at a median tmax of 2 h, and the mean t½ was approximately 8 h for both doses; plasma systemic exposures increased slightly more than dose-proportionally. After 4 weeks, reductions in 23-h WMG and FPG were observed in all treatment groups compared with placebo and were significantly lower for 250-mg JNJ-41443532 and pioglitazone. HOMA-IR was lower for all treatment groups, but significantly lower only for pioglitazone. Conversely, HOMA-%B was increased for all groups, but significantly increased only for 250-mg JNJ-41443532. All groups, including placebo, had decreased body weight over time. There were no clinically significant findings during routine safety assessments and the incidence of treatment-emergent adverse events was similar across all groups.
CONCLUSIONS: Administration of JNJ-41443532 resulted in modest improvement in glycaemic parameters compared with placebo, and was generally well tolerated in patients with T2DM.
