Brief Summary

The protocol describes a randomized, double-blind, placebo-controlled trial with independent sub-studies of setmelanotide in patients with obesity and at least one of the specific gene variants in the Melanocortin-4 Receptor pathway:

* POMC or PCSK1 (Sub-study 035a)

* LEPR (Sub-study 035b)

* SRC1 (Sub-study 035c)

* SH2B1 (Sub-study 035d)
