| Popis: | Background: Praliciguat (IW-1973), a soluble guanylate cyclase stimulator, has been shown to augment nitric oxide (NO) signaling and reduce fasting plasma glucose and proteinuria in an animal model of diabetic nephropathy. In healthy adults, repeated oral doses of 15-40 mg were tolerated and lowered blood pressure (BP). Methods: This Phase 2a, double-blind, placebo (PBO)-controlled study assessed the effects of oral praliciguat in 26 patients with type 2 diabetes mellitus (T2DM) and hypertension on stable glycemic and BP-lowering therapy. Most (69%) were also on statins. Two praliciguat regimens were tested: (1) 40 mg QD for days 1-14 (N=10), and (2) 20 mg BID for days 1-7 then 40 mg QD for days 8-14 (N=10). Assessments included serum chemistry, fasting plasma glucose, BP and heart rate, platelet function, reactive hyperemia index (RHI), plasma biomarkers, and adverse events (AEs). Results: Results were similar for both praliciguat regimens and are here combined. After 14 days of treatment, praliciguat-treated patients had notable differences in least squares mean change from baseline (95% CI) relative to PBO in 24-hour mean arterial pressure [-4.7 mmHg (-10, 0.8)], heart rate [2.9 bpm (-0.7, 6.5)], fasting glucose [-13 mg/dL (-32, 7)], HOMA-IR [-26 (-58, 7)], total serum cholesterol [-26 mg/dL (-44, -7)], and LDL cholesterol [-20 mg/dL (-37, -3)]. Praliciguat had no effect on platelet function or RHI. Among the exploratory biomarkers tested, levels of the endogenous NO synthase inhibitor asymmetric dimethylarginine were lower in praliciguat vs. PBO recipients. Both praliciguat dose regimens were generally well tolerated. Except for one serious AE of upper gastrointestinal hemorrhage, AEs in praliciguat-treated patients were mild. Conclusion: In this initial trial, praliciguat had beneficial effects on BP and metabolic parameters in T2DM patients with hypertension on standard therapies. Further clinical investigation of praliciguat in T2DM patients is warranted. Disclosure J.P. Hanrahan: Employee; Self; Ironwood. J.D. Wakefield: Employee; Self; Ironwood Pharmaceuticals, Inc..
