What This Study Did, in Plain Language

What Was Tested

This clinical trial, phase iii paper looks at Alpha-MSH and Setmelanotide.

No approved therapies for patients younger than 6 years old currently exist.

Who Took Part

The age groups tagged for this paper are young children, both men and women.

This phase 3, open-label, multicentre trial, conducted across six sites in the USA, the UK, Spain, and Australia, enrolled eligible patients aged 2-5 years who had hyperphagia and obesity due to biallelic POMC (including PCSK1) or LEPR variants or genetically confirmed BBS.

How the Study Was Run

The design is described as open-label and multicenter.

Everyone knew when Alpha-MSH was being given (open label), which is simpler to run but leaves more room for expectations to affect what is reported.

Running at several centres spread the Alpha-MSH study over different clinics and patient groups.

Additional endpoints measured safety, hunger, weight-related outcomes, and caregiver burden.

The study is registered at ClinicalTrials.gov (NCT04966741) and is complete.

What Was Measured

Topics PubMed links to this paper include Receptor, Melanocortin, Type 4, alpha-MSH, Obesity, Pro-Opiomelanocortin, Pediatric Obesity and Hyperphagia.

Our Notes on the Compounds

Alpha-MSH: A 13-amino-acid hormone that drives skin pigmentation and calms inflammation; afamelanotide (Melanotan I) is an analog.

Setmelanotide: An FDA-approved melanocortin-4 receptor agonist for rare genetic obesity (POMC, PCSK1, LEPR deficiency and Bardet-Biedl syndrome).
