What this trial studies

This clinical trial evaluates the efficacy and safety of metformin in patients diagnosed with post chronic pancreatitis diabetes mellitus (PPDM-C). Participants will be randomly assigned to receive either metformin or a placebo to assess its impact on glycemic control and the incidence of adverse effects. The study aims to address the lack of standardized management strategies for PPDM-C, which is a condition that arises in a significant number of chronic pancreatitis patients. By focusing on this specific patient population, the trial seeks to provide insights into effective treatment options.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with a diagnosis of chronic pancreatitis and diabetes that developed at least three months after their pancreatitis diagnosis.

Not a fit: Patients with type 1 diabetes or secondary diabetes not caused by chronic pancreatitis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve glycemic control in patients suffering from diabetes related to chronic pancreatitis.

How similar studies have performed: While there is limited research specifically on metformin for PPDM-C, metformin has shown efficacy in other diabetes populations, suggesting potential for success in this novel application.
