Effekter och bieffekter av bantningspreparatet Tesofensine

[Eddie Vedder]

Tesofensine är ett nytt bantningspreparat som fått en del uppmärksamhet på sistone. I den här nypublicerade danska studien undersökte man bantning plus regelbundet intag av Tesofensine och bantning plus placebo.

Summary
Background
Weight-loss drugs produce an additional mean weight loss of only 3—5 kg above that of diet and placebo over 6 months, and more effective pharmacotherapy of obesity is needed. We assessed the efficacy and safety of tesofensine—an inhibitor of the presynaptic uptake of noradrenaline, dopamine, and serotonin—in patients with obesity.
Methods
We undertook a phase II, randomised, double-blind, placebo-controlled trial in five Danish obesity management centres. After a 2 week run-in phase, 203 obese patients (body-mass index 30−≤40 kg/m2) were prescribed an energy restricted diet and randomly assigned with a list of randomisation numbers to treatment with tesofensine 0·25 mg (n=52), 0·5 mg (n=50), or 1·0 mg (n=49), or placebo (n=52) once daily for 24 weeks. The primary outcome was percentage change in bodyweight. Analysis was by modified intention to treat (all randomised patients with measurement after at least one dose of study drug or placebo). The study is registered with ClinicalTrials.gov, number NCT00394667.
Findings
161 (79%) participants completed the study. After 24 weeks, the mean weight loss produced by diet and placebo was 2·0% (SE 0·60). Tesofensine 0·25 mg, 0·5 mg, and 1·0 mg and diet induced a mean weight loss of 4·5% (0·87), 9·2% (0·91), and 10·6% (0·84), respectively, greater than diet and placebo (p<0·0001). The most common adverse events caused by tesofensine were dry mouth, nausea, constipation, hard stools, diarrhoea, and insomnia. After 24 weeks, tesofensine 0·25 mg and 0·5 mg showed no significant increases in systolic or diastolic blood pressure compared with placebo, whereas heart rate was increased by 7·4 beats per min in the tesofensine 0·5 mg group (p=0·0001).
Interpretation
Our results suggest that tesofensine 0·5 mg might have the potential to produce a weight loss twice that of currently approved drugs. However, these findings of efficacy and safety need confirmation in phase III trials.
