ABSTRACT
Chiglitazar (CHI) is a potent and selective peroxisome proliferator-activated receptor potentially for the treatment of patients with type 2 diabetes mellitus (T2DM). An open-label, randomized, 3-period crossover and self-controlled study was conducted to investigate drug-drug interaction potential between CHI and metformin hydrochloride (MET). Eligible subjects received a single oral dose of CHI (48 mg), MET (1000 mg), or a combination in each period, followed by serial blood sampling collected for up to 48 hours postdose, and safety was assessed throughout the trial. The area under the plasma concentration-time curves from time 0 to 48 hours (AUC0-48 h ) of CHI was similar following administration alone or with MET (AUC0-48h , 12 540 ng·h/mL [9811-15 269 ng·h/mL] vs 12 130 ng·h/mL [9304-14 956 ng·h/mL]; 90% confidence interval [CI] of its geometric mean ratio [GMR], 89.7%-103.8%), whereas the maximum concentration (Cmax ) of CHI was reduced during coadministration, as its 90%CI of the GMR was slightly outside the acceptance range for bioequivalence (Cmax , 1620 ng/mL [1418-1822 ng/mL] vs 1420 ng/mL [1049-1791 ng/mL], 90%CI GMR, 77.%-94.1%). However, it was not considered clinically meaningful. The MET exposures remained consistent in the absence or presence of CHI (AUC0-48 h , 12 570 ng·h/mL [10681-14 459 ng·h/mL] vs 13 190 [10973-15 407 ng·h/mL); 90%CI of GMR 99.1%-110.5%; Cmax , 1790 ng/mL [1448-2132 ng/mL] vs 1820 ng/mL [1510-2130 ng/mL]; 90%CI of GMR, 94.2%-110.9%). No moderate to severe adverse events were reported. Our study indicated no clinically significant pharmacokinetic drug-drug interaction between CHI and MET and demonstrated good tolerance in subjects. These results support future application of CHI in combination with MET for treatment of T2DM.
