Understanding how TMPRSS6 relates to liver and metabolism in LEPRD and lipodystrophy

Official title: Targeting the Hepatic BMP-SMAD Pathway in Leptin Receptor Deficiency (LEPRD): A New Strategy for Treating Severe Genetic Obesity or Leptin Deficiency

Run by Azienda Ospedaliero Universitaria Maggiore della Carita · NCT07833592 · Data updated 2026-11-12

This observational study tests whether TMPRSS6 levels or activity relate to blood sugar, lipids, body fat, and liver health in people with leptin receptor deficiency or genetic lipodystrophy.

Is this trial a fit for you?

Likely a good fit

Individuals of any age with LEPRD or genetically determined leptin deficiency-associated lipodystrophy, including those on setmelanotide or metreleptin.

Probably not a fit

Participants without these rare conditions or those not showing TMPRSS6-related signals may not experience direct personal benefits.

What this trial studies

This study collects blood samples and clinical data from participants with LEPRD or genetically determined leptin deficiency-related lipodystrophy to explore the role of TMPRSS6 in metabolic and liver health. Researchers will measure TMPRSS6 and other metabolic markers and analyze how these relate to glucose control, lipid levels, body fat distribution, and liver status. The goal is to better understand mechanisms driving metabolic complications in these rare conditions and to identify potential new targets for treatment. Participation is observational and involves no assigned interventions beyond standard care and study blood work. Adults and children with LEPRD or related lipodystrophy, including those on setmelanotide or metreleptin, may contribute data.

Why it matters

Potential benefit: If successful, the study could reveal new biological pathways that influence metabolic and liver health in LEPRD and lipodystrophy, informing future therapies.

How similar studies have gone: There is limited prior work directly linking TMPRSS6 and metabolic/liver outcomes in LEPRD or lipodystrophy; this represents a relatively novel observational exploration.
