Use of sibutramine in obese mexican adolescents: a 6-month, randomized, double-blind, placebo-controlled, parallel-group trial.
Clin Ther 2006; 28(5):770-82CT

Abstract

BACKGROUND

The prevalence of overweight and obesity in children and adolescents is increasing in both the United States and Mexico.

OBJECTIVE

The goal of this article was to assess the efficacy and safety of sibutramine in obese Mexican adolescents.

METHODS

This was a 6-month, randomized, double-blind, placebo-controlled, prospective clinical trial of sibutramine QD. Male and female patients aged 14 to 18 years with sex-specific body mass index (BMI) for age and sex >85th percentile were eligible. The primary end points for the trial were the baseline versus end point absolute values for body weight, BMI, and percentage of the initial BMI (%BMI); secondary end points were waist circumference and percentage of the initial waist circumference (%waist). These were measured at days -15, 0, 30, 60, 90, 120, 150, and 180 of the study. Quality of life was assessed at the study start and end using the 36-Item Short-Form Health Survey (SF-36) questionnaire. Blood pressure and heart rate were assessed, and adverse events (AEs) were recorded. Both groups received individually tailored diet and exercise programs.

RESULTS

Forty-six patients (age range, 14-18 years) with a BMI >95th percentile for age were included (sibutramine group, n = 23 [14 females, 9 males]; placebo group, n = 23 [12 females, 11 males]). Twenty-one patients in the sibutramine group and 19 patients in the placebo group completed the 6-month trial. Using the intent-to-treat data, weight (mean [SD]) in the sibutramine group changed from 92.5 (14.6) kg to 85.7 (14.4) kg, for a net weight loss of 7.3 kg (95% CI 4.6-9.9), a waist circumference loss of 8.0 cm (95% CI, 4.7-11.3), and a % BMI loss of 9.2% (95% CI, 6.9-11.6). In the placebo group, weight changed from 98.9 (22.7) kg to 94.6 (22.5) kg, a weight loss of 4.3 kg (95% CI, 1.7-6.9), a waist circumference loss of 3.8 cm (95% CI, 0.7-7.0), and a %BMI loss of 5.2% (95% CI, 2.4-7.9) (P < 0.05 for all intragroup comparisons; P > 0.05 for the intergroup comparisons). Mean (SD) scores on the SF-36 scale in the sibutramine group changed from 78.0 (13.3) at baseline to 84.8 (7.4) at study end (P < 0.05); the respective values in the placebo group were 82.8 (10.3) and 87.3 (7.6) (P < 0.05). At base-line, systolic blood pressure (SBP) was 116.7 (5.9) mm Hg in the sibutramine group and 118.3 (7.6) mm Hg in the placebo group; at end point, the respective SBPs were 112.4 (9.6) mm Hg and 112.6 (6.5) mm Hg. At baseline, diastolic blood pressure (DBP) was 78.9 (4.5) mm Hg in the sibutramine group and 79.5 (5.2) mm Hg in the placebo group; at end point, the respective DBPs were 73.5 (6.3) mm Hg and 76.6 (6.2) mm Hg. At baseline, heart rate was 76.3 (6.4) beats/min in the sibutramine group and 81.1 (9.5) beats/min in the placebo group; at end point, the respective findings were 79.8 (8.8) beats/min and 77.6 (8.6) beats/min (P > 0.05 for all preceding intergroup comparisons). One patient in the sibutramine group had increased blood pressure (at month 3) and 3 had increased heart rate (at months 1, 2, and 4); 2 patients receiving placebo had increased blood pressure (month 3) and 2 had increased heart rate (at months 1 and 3). These changes disappeared in 1 week and did not require treatment or trial suspension. Additionally, in the sibutramine group, 3 patients experienced 4 mild AEs: headache, dry mouth, headache with nausea, and headache with weakness and paleness (P > 0.05). In the placebo group, 3 patients experienced 4 mild AEs: 2 cases of headache, as well as 1 case of headache with somnolence and 1 case of headache with dry mouth (P > 0.05).

CONCLUSION

Sibutramine 10 mg QD in addition to diet and exercise was effective and generally well tolerated in this population of obese Mexican adolescents.
