BIM-22493 does not alter animal behaviour Activation of the melanocortin pathways has been associated with several non-feeding related activities. Increased yawning, muscular stiffness, stretching and penile erection have all been described as consequences of activation of the melanocortin pathways (32; 40-42). Observation of the animals before, during and after the administration of BIM-22493 verified that we did not see these side effects in our animals. The lack of muscular stiffness can also be observed by the increase in activity during the treatment period. Adverse effects that could result in confounding factors in regards to food intake are headaches, asthenia, nausea, vomiting and diarrhea, as mentioned in clinical studies with another MC4R agonist (32). Cages were inspected daily for vomiting and diarrhea, both of which were never observed. At all times, the monkeys were eager to accept a small peanut butter treat in the afternoon. From personal observations the peanut butter treat will be rejected when the animal has nausea, for instance when induced by GLP-1 administration (data not shown). Further, studies in beagles also failed to demonstrate an increase in nausea (personal communication with M Culler). In contrast, LY2112688 caused gapping, a sign of nausea in 2 animals. This is consistent with the findings of the clinical study with LY2112688 (32). Finally, food intake did return to normal levels during the course of drug tre ment in the current experiment.

Supplementary Figure 2. Food intake is decreased in lean NHP treated with BIM-22493. A) Daily food intake measured during exposure of the animals (n=6) to a minipump filled with saline (weeks 1, 3, 5 and 7) or increasing doses of BIM-22493 (weeks 2, 4 and 6). B) Food intake was calculated as a daily average over 5 days during the minipump implantations. Data was analyzed as a repeated measures ANOVA (p<0.0001) with Bonferroni post hoc testing. Each dose was significantly decreased compared to weeks 3 and 5 (p<0.05 for 0.17 dose, p<0.001 for 0.5 and 1.5 mg/kg/day dose). None of the doses were significantly different from each other.

Supplementary Figure 4. Food Intake (A) and Body Weight (B) during the treatment period (0.5 mg/kg/day) and an extended washout period. An ivGTT test was performed 12 weeks after washout where we calculated HOMA-IR (C) and the total insulin secretion during the glucose bolus (D). All data was analysed using ANOVA with repeated measures and Dunnett’s posthoc test; p<0.05 was considered significant.

Supplementary Figure 6. Representative plots of 4 animals treated with 0.5 mg/kg/day of BIM-22493 or
LY2112688. All changes in systolic blood pressure and heart rate are represented as changes compared to the
vehicle period preceding the compound. Both vehicle and compound were delivered via osmotic minipump as
described in the materials and method section. One animal is not reported as we noticed an increase of 50mm Hg
two hours post-implantation of the 0.17 mg/kg/day dose. This animal was removed from the 0.5 mg/kg/day
LY2112688 experiment. However, no increases were noted when this animal was given 0.5 mg/kg/day of BIM-
22493.
