Number of participants that the trial has enrolled

372

Results

For the primary efficacy outcome of absolute weight reduction after 24 weeks, both groups receiving tesofensine had greater weight loss than placebo (Placebo: 1.9 (SE: 0.3) kg; 0.25 mg tesofensine: 5.3 (SE: 0.4) kg, and 0.50 mg tesofensine: 8.6 (SE: 0.5) kg).

Baseline Characteristics

The mean age of the sample was 40.8 (SD:10.2) years and there was a greater participation of women than men (85.2% vs. 14.8%). Baseline anthropometric, clinical, and metabolic parameters were similar in the three study groups, as well as comparable variability of data.

Participant flow

Out of 411 Mexican subjects assessed for this study, 372 were randomized after corroborating fulfillment of all eligibility criteria. Recruitment was balanced among the two centers with 188 (50.5%) from AMIC and 184 (49.5%) from INER. Most subjects completed the 24-week follow-up period (77.4%, n=288). Of 84 subjects who discontinued treatment, 14.3% (n=12) were attributable to an adverse event.

Adverse events

Out of all subjects, a total of 242 (65.1%) experienced at least one adverse event (AE). The proportion of participants experiencing an AE across study groups was similar. There was a total of 1198 AE throughout the study including follow-up, of which 2 were severe (tendinous rupture in one patient receiving 0.5 mg tesofensine, and cholecystitis in a patient treated with 0.25 mg tesofensine); both were classified as unlikely related to the treatment.

Outcome measures

For the primary efficacy outcome of absolute weight reduction after 24 weeks, both groups receiving tesofensine had greater weight loss than placebo (Placebo: 1.9 (SE: 0.3) kg; 0.25 mg tesofensine: 5.3 (SE: 0.4) kg, and 0.50 mg tesofensine: 8.6 (SE: 0.5) kg).
