What this trial studies

This pilot study aims to evaluate the feasibility and acceptability of paricalcitol in adults suffering from chronic pancreatitis. It will assess the drug's effects on health-related quality of life, imaging results, and biomarker analysis. Participants will undergo MRI and DEXA scans to monitor their condition and bone mineral density, comparing those receiving paricalcitol to a placebo group. The study will also collect routine lab results to identify any adverse events or safety concerns throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with a diagnosis of chronic pancreatitis not caused by gallstones, medications, trauma, or autoimmune conditions.

Not a fit: Patients with chronic pancreatitis due to gallstones or other specific etiologies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that alleviates symptoms of chronic pancreatitis.

How similar studies have performed: While this approach is novel, preclinical evidence suggests that vitamin D analogues may have beneficial effects on pancreatitis.
