Summary
This is a phase 3 open-label, clinical study to evaluate the efficacy, safety and tolerability of setmelanotide over 1 year of treatment, in pediatric participants aged 2 to <6 years with obesity due to either biallelic variants of the pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1) or leptin receptor (LEPR) genes or Bardet-Biedl Syndrome (BBS).
Eligibility Criteria
Key Inclusion Criteria
- Participants must have obesity due to either:
- POMC, PCSK1, or LEPR deficiency, confirmed by genetic testing demonstrating biallelic variants that are interpreted as pathogenic, likely pathogenic, or of undetermined significance (VUS) by the American College of Medical Genetics and Genomics criteria (ACMG), or
- BBS confirmed clinical and genetic diagnosis
- Age between 2 to 9.0% at screening
- History of significant liver disease
- Glomerular filtration rate (GFR) <60 milliliter per minute per 1.73 meter square (mL/min/1.73 m^2)
- History or close family history of melanoma, or participant history of oculocutaneous albinism.
- Significant dermatologic findings relating to melanoma or pre-melanoma skin lesions (excluding non-invasive basal or squamous cell lesion)
- Participation in any clinical study with an investigational drug/device within 3 months prior to the first day of dosing.
- Previously enrolled in a clinical study involving setmelanotide or any previous exposure to setmelanotide.
- Significant hypersensitivity to any excipient in the study drug.
- Inadequate hepatic function
- Any other uncontrolled endocrine, metabolic or medical condition(s) known to impact body weight
Other protocol defined Inclusion/Exclusion criteria may apply.
