OBJECTIVE: Very-low-calorie diets (VLCDs) are used to promote short-term weight loss in obese patients. However, long-term maintenance of weight loss is generally poor. We assessed the efficacy and safety of sibutramine in maintaining weight loss achieved in obese patients by means of a 3-month VLCD. DESIGN: A multicenter double-blind, parallel-group trial conducted over 18 months, following a 3-month open label VLCD run-in. SETTING: Eight hospital centers in The Netherlands, with subsequent follow-up in general practice. SUBJECTS: A total of 221 obese subjects, of whom 189 were randomized (mean screening BMI 36.6 kg/m(2); mean age 42.6 y). MEASUREMENTS: Patients were given a 3-month VLCD and were required to lose 10% or more of their initial weight. A total of 189 patients completed this phase (mean percentage weight loss 14.5+/-3.2%) and were randomized to sibutramine 10 mg/day (n=94) or matching placebo (n=95). All patients received a recommended diet and exercise program. The primary analysis was outcome in terms of achieving 80% weight maintenance of the VLCD period at month 18. Secondary analysis was percentage of initial weight loss maintained at months 6, 12, 18 and end point. RESULTS: At month 18, the odds ratio for achieving successful weight maintenance was 1.76 (95% CI 1.06, 2.93) in favor of sibutramine (P=0.03). In intention-to-treat analysis, more than 80% of the weight loss achieved during the VLCD phase was maintained by 70, 51 and 30% of sibutramine-treated patients at months 6, 12 and 18, respectively, compared to 48, 31 and 20% of placebo-treated patients. The differences between the treatment groups were significant (P< or =0.03) at all time points. CONCLUSION: Weight loss achieved with a VLCD is more effectively maintained with sibutramine in combination with a recommended diet and exercise program than with placebo over a follow-up period of 18 months. Sibutramine is well tolerated, with a safety profile consistent with that seen in other previous trials.
