Efficacy and safety of fixed dose combination of Sitagliptin, metformin, and pioglitazone in type 2 Diabetes (IMPACT study): a randomized controlled trial.

BACKGROUND: Due to the progressive decline in ß-cell function, it is often necessary to utilize multiple agents with complementary mechanisms of action to address various facets and achieve glycemic control. Thus, this study aimed to evaluate the efficacy and safety of a fixed-dose combination (FDC) of metformin/sitagliptin/pioglitazone (MSP) therapy vs. metformin/sitagliptin (MS) in type 2 diabetes mellitus (T2DM). METHODS: In this phase 3, multicenter, double-blind study, patients with T2DM who exhibited inadequate glycemic control with HbA1c of 8.0-11.0% while taking ≥1500 mg/day metformin for at least 6 weeks were randomized to receive either FDC of MSP (1000/100/15 mg) or MS (1000/100 mg) per day for 24 weeks. The primary outcome measure was the change in HbA1c, and secondary outcomes included changes in fasting plasma glucose (FPG), postprandial plasma glucose (PPG), and body weight from baseline to 24 weeks along with safety and tolerability. RESULTS: Among the 236 patients randomized, 207 (87.71%) successfully completed the study. All baseline characteristics were comparable between the FDC of MSP and MS groups. There was a subsequent significant reduction of HbA1c in FDC of MSP (- 1.64) vs. MS (- 1.32); between groups was [- 0.32% (95% CI, - 0.59, - 0.05)], P = 0.0208. Similar reductions were found in FPG [- 13.2 mg/dL (95% CI, - 22.86, - 3.71)], P = 0.0068, and PPG [- 20.83 mg/dL (95% CI, - 34.11, - 7.55)], P = 0.0023. There were no significant changes in body weight. A total of 27 adverse effects (AEs) and one severe AE were reported, none of which were related to the study drug. CONCLUSION: The FDC of MSP demonstrated significant efficacy in managing glycemic indices and could serve as a valuable tool for physicians in the management of Indian patients with T2DM.

Therapeutic efficacy of artemisinin combination therapies and prevalence of S769N mutation in PfATPase6 gene of Plasmodium falciparum in Kolkata, India

OBJECTIVE@#To study the in vivo efficacy of these two ACTs in the treatment of Plasmodium falciparum (P. falciparum malaria) in Kolkata and to determine the prevalence of mutant S769N codon of the PfATPase6 gene among field isolates of P. falciparum collected from the study area.@*METHODS@#A total of 207P. falciparum positive cases were enrolled randomly in two study arms and followed up for 42 days as per WHO (2009) protocol. A portion of PfATPase6 gene spanning codon S769N was amplified and sequenced by direct sequencing method.@*RESULTS@#It was observed that the efficacy of both the ACT regimens were highly effective in the study area and no mutant S769N was detected from any isolate.@*CONCLUSIONS@#The used, combination AS+SP is effective and the other combination AM+LF might be an alternative, if needed.
