Summary
This was a long-term extension trial to study the safety and tolerability of continued setmelanotide treatment in participants who had completed a previous clinical trial on treatment with setmelanotide for obesity associated with genetic defects upstream of the Melanocortin-4 (MC4) receptor in the leptin-melanocortin pathway.
