Official title: Gonadic Function and Pubertal Development in Female Patients With Classic Galactosemia

Run by IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT07461519 · Data updated 2026-11-12

This project will collect clinical, hormone, growth, and fertility information on girls and young women with classic galactosemia to see if specific factors are linked to ovarian insufficiency and pubertal outcomes.

Is this trial a fit for you?

Likely a good fit

Female patients born between January 1, 1980 and December 31, 2024 with genetically confirmed classic galactosemia who are followed at participating Pediatric Endocrinology or Inherited Metabolic Disease centers and can provide informed consent.

Probably not a fit

Patients with known chromosomal abnormalities, ovarian insufficiency from other causes, males, or those without genetic confirmation of classic galactosemia are unlikely to benefit from the study's specific findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a large multicenter Italian observational cohort of genetically confirmed female patients with classic galactosemia, aiming to document clinical, auxological, hormonal, developmental, and fertility-related features across key pubertal stages. Data will be compared with general population references and analyzed to identify factors associated with primary ovarian insufficiency (POI). The study includes standardized clinical visits and retrospective and prospective data collection from participating Pediatric Endocrinology and Metabolic Disease centers. Secondary outcomes include final height relative to familial targets, quality of life, psycho-emotional adjustment, and cognitive/psychomotor development.

Why it matters

Potential benefit: If successful, the study could identify predictors of ovarian insufficiency and inform timing and options for fertility preservation and reproductive counseling for affected women.

How similar studies have gone: Previous smaller single-center reports and case series have repeatedly shown high rates of ovarian dysfunction in classic galactosemia, but large homogeneous multicenter cohorts addressing risk factors and fertility features have been lacking.
