Pasireotide LAR and bone health in adults with acromegaly

Effects of Pasireotide Lar Therapy on Bone Metabolism

Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT07179926

This study will test whether switching adults with uncontrolled acromegaly to pasireotide LAR changes bone turnover and the risk of vertebral fractures.

What this trial studies

This observational project follows adults with acromegaly whose disease remains uncontrolled after at least six months of first-generation somatostatin receptor ligand therapy and who are switched to pasireotide LAR, with a retrospective comparison group of patients switched to pegvisomant. Bone health will be monitored using morphometric spine radiography to detect vertebral fractures and by tracking markers of bone turnover and hormonal control as part of routine care. The prospective cohort will be followed after the treatment switch, while historical data from the retrospective cohort will be reviewed to compare skeletal outcomes. The aim is to characterize how different second-line medical therapies relate to bone metabolism and fracture prevalence in this population.

Who should consider this trial

Good fit: Adults over 18 with acromegaly not controlled after ≥6 months on first-generation SRLs who are switching to pasireotide LAR (prospective) or who previously switched to pegvisomant (retrospective) and can provide informed consent.

Not a fit: Patients with well-controlled acromegaly, those under 18, or those unable to undergo spine radiography are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, results could help clinicians choose treatments that reduce bone fragility and vertebral fractures in people with acromegaly.

How similar studies have performed: Prior studies have documented hormonal effects of pasireotide and pegvisomant, but bone-specific outcomes and vertebral fracture data are limited, making this a relatively under-studied area.
