Dirlotapide is a novel microsomal triglyceride transfer protein inhibitor intended for the treatment and management of obesity in dogs. The biologic effects of dirlotapide, weight loss, decreased food intake, increased fecal fat, decreased serum cholesterol, and body composition, were evaluated in a controlled, blinded study. Sixteen obese beagles were randomized to treatment with placebo (n = 4) or dirlotapide (n = 12) following a 2-week acclimation period in which baseline data were collected. The dirlotapide dose, adjusted to produce weight loss for 3 months and then stabilize body weight for 1 month (weight management), produced a significant difference (expressed as a percentage of baselines) in weekly weight loss, food intake, fecal fat, serum cholesterol concentration, and body composition (measured by dual energy X-ray absorptiometry) compared with placebo treatment (P < 0.05). The initial dirlotapide dosage of 0.5 mg/kg (10 times the initial label dose) resulted in a high rate of weight loss (3.3% weekly) and anorexia, emesis, and loose stools for some dogs. A 25% dose reduction (mean dosage: 0.36 mg/kg) followed by biweekly 25% dose adjustments based on individual weight loss, produced 1-2% weekly weight loss and total weight loss of 18.8% in 12 weeks at a final mean dosage of 0.41 mg/kg (range: 0.15-0.60); a dosage range of 0.10-0.34 mg/kg stabilized body weight. Body weight changes for placebo-treated dogs were -0.8% to +0.9% weekly; total weight gain during the weight loss phase was 10.6%. No apparent change in food intake, percentage of fecal fat, and serum cholesterol was observed in the placebo group. Food intake and body weight increased when dirlotapide was discontinued. Dirlotapide produced weight loss by both reducing appetite (about 90% of the weight loss activity) and by increasing fecal fat excretion (about 10% of the weight loss activity).

Dirlotapide was evaluated in the management of obesity in dogs in two multicenter, clinical studies in North America. A total of 335 obese dogs of various breeds were randomized to dirlotapide or placebo in a 2:1 ratio. Dirlotapide was administered orally once daily to dogs at an initial dose of 0.05 mg/kg, increased after 14 days to 0.1 (study B, label dose) or 0.2 mg/kg (study A) and then adjusted according to individual weight loss at 28-day intervals. Dogs were examined and weighed, and body condition scores (BCSs) were recorded every 28 days. Study A had three consecutive phases: weight loss (16 weeks, day 0-112); weight management (12 weeks); and post-treatment (8 weeks). Study B had a weight loss phase only. For dirlotapide-treated dogs, mean weight loss by day 112 was 11.8-14.0% compared with 3.0-3.9% for placebo (P = 0.0001). In study A, weight losses for dirlotapide were 19.3% after 12 weeks of weight management and 16.7% (regain of 3.4%) by 8 weeks after dirlotapide was discontinued. In both studies, dogs in both treatments had emesis, lethargy, anorexia, diarrhea, and mildly elevated hepatic transaminase activity, that resolved spontaneously with time. These were experienced more frequently with dirlotapide. Improved activity levels and BCS for >50% dogs were reported with dirlotapide. Dirlotapide was safe and effective in the reduction and management of body weight in obese dogs.
