Brief summary

A trial to compare the weekly and daily formulations of setmelanotide in participants with genetic defects in the melanocortin-4 receptor pathway.

Detailed description

This study is designed to compare the safety, pharmacokinetics, and efficacy of weekly and daily formulations of setmelanotide in participants with obesity associated with biallelic or heterozygous POMC (pro-opiomelanocortin), PCSK1 (proprotein convertase subtilisin/kexin Type 1), LEPR (leptin receptor) genetic variants, and participants with Bardet-Biedl Syndrome (BBS).

MeasureTime frameDescription
Number of Participants With Injection Site Reactions (ISRs) From Baseline Through Week 13Baseline through Week 13The injection site evaluation included the identification of areas of erythema, edema, and induration, as well as the presence of localized pain, tenderness, and itching. Baseline was defined as the last available measurement prior to the first dose of setmelanotide or placebo. Injection site reactions frequency of once daily (QD) and once weekly (QW) were reported. Data are reported by dose level (treatment regimen) in the DB Period. Number of participants with injection site reactions according to severity were reported.
Number of Participants With ISRs From Week 14 Through Week 27Week 14 through Week 27The injection site evaluation included the identification of areas of erythema, edema, and induration, as well as the presence of localized pain, tenderness, and itching. Injection site reactions frequency of QD and QW were reported. Data are reported by dose level (treatment regimen) in the OL Period. Number of participants with injection site reactions according to severity were reported.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)From first dose of study drug administration up to Week 30An adverse event (AE) is any untoward medical occurrence in a participant or clinical trial participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. The AEs reported after the start of the run-in period were considered TEAEs.

Pre-assignment details

Number of Participants With ISRs From Week 14 Through Week 27

The injection site evaluation included the identification of areas of erythema, edema, and induration, as well as the presence of localized pain, tenderness, and itching. Injection site reactions frequency of QD and QW were reported. Data are reported by dose level (treatment regimen) in the OL Period. Number of participants with injection site reactions according to severity were reported.

Time frame: Week 14 through Week 27

Population: Participants in the Safety Analysis Set with available data were analyzed.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

An adverse event (AE) is any untoward medical occurrence in a participant or clinical trial participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. The AEs reported after the start of the run-in period were considered TEAEs.

Time frame: From first dose of study drug administration up to Week 30

Population: Participants in the Safety Analysis Set (all participants who received at least 1 dose of protocol-specified study drug) were analyzed.
