Weight Loss

October 1, 2012

Zafgen issued results from a phase Ib trial of beloranib for the reduction of body fat, rapid weight loss and improvements in cardiovascular disease risk in obese females. This randomized, double-blind, placebo-controlled study enrolled obese women with a mean (SEM) age of 45.7 years, body weight of 104.9kg and BMI of 39.5kg/m2. Subjects were randomized into three arms and received beloranib 3.0mg or 6.0mg, or placebo, twice weekly for four weeks. Patients were allowed to eat normally and were not counseled to change their exercise habits. After four weeks, subjects on 3.0mg beloranib lost an average of 4.7kg from baseline (p=0.0008), 6.0mg beloranib lost 6.7kg (p=0.0013) and placebo-dosed subjects gained an average of 0.2kg. Body composition measurements were consistent with reduced adipose tissue mass. Despite the fact that they lost weight, hunger tended to be reduced (-28% with 3.0mg, -52% with 6.0mg, -2% with placebo). Blood pressure (BP) and glucose did not change with treatment. The drug was well tolerated. The most frequent adverse events were mild diarrhea, nausea, headache, dizziness, infusion site injury and sleep disturbance. Based on these data, Zafgen will expand its clinical development program to include more subjects.

Acacia Pharma issued results from a phase IIa trial of APD209 for cancer cachexia. The trial enrolled 13 subjects with an average weight loss of 11.4% in the previous six months. The subjects received APD209 for eight weeks. The primary efficacy endpoint was major response, defined as an increase in quadriceps muscle size of at least 4% and/or an increase of at least 10% in quadriceps strength. Seven subjects completed the eight week course of treatment, with six achieving a major response. Among the responders, the average increase in quadriceps volume was 6% and quadriceps strength rose on average 16%. Hand grip strength increased on average 17%. Physical activity was also markedly improved in three subjects. In two of these subjects the average daily step count more than doubled between the start and end of treatment. Side effects related to APD209 were generally mild.
