2046-P: NS-0200 (Leucine-Metformin-Sildenafil) Reduces Weight in Obese Subjects: A 24-Week Randomized Trial
2019
We previously showed leucine to activate the SIrt1/AMPK/NO pathway and to synergize with other activators of this pathway, and developed NS-0200 (leucine-metformin-sildenafil combination) to treat diseases of energy dysregulation. During a previous trial of NS-0200 of nonalcoholic fatty liver disease we noted significant weight loss induced by NS-0200. Accordingly, we have conducted a 24-week placebo-controlled double-blind trial in 258 weight-stable obese subjects to evaluate the effects of leucine (1.1 g) + sildenafil (1 or 4 mg) with or without metformin (500 mg) administered b.i.d. on weight loss in the absence of lifestyle modification; data presented are for the 202 per-protocol completers. Leu/Met/Sil 1.0 or 4.0 mg and Leu/Sil 4.0 mg produced significant weight loss, while LeuSil 1.0 mg did not. Leu/Met/Sil 1.0 mg exerted the greatest effect (2% placebo-adjusted weight loss, p 2, vs. 42% in Caucasians, and Leu/Met/Sil 1.0 resulted in a 61% decrease in both insulin and HOMAIR(p 2 (p=0.017); those with elevated insulin at baseline lost ∼twice as much weight as those with lower insulin (-3.8 vs. -1.8%), and 30% of this subgroup achieved 5% weight loss vs. 6% of placebo. These data indicate NS-0200 results in significant 6-month weight loss, especially in insulin-resistant subjects, and suggest therapeutic utility for obese insulin-resistant individuals.
