Pioglitazone Versus Empagliflozin for Chronic Pancreatitis/Recurrent Acute Pancreatitis Associated Diabetes Mellitus (PEP-DM)

March 30, 2026 updated by: Yogish C. Kudva, Mayo Clinic

Randomized, Parallel Group, Dose Escalation Trial of Pioglitazone Versus Empagliflozin for Chronic Pancreatitis/Recurrent Acute Pancreatitis Associated Diabetes Mellitus: The PEP-DM Trial

The purpose of this study is to evaluate efficacy of pioglitazone (PIO) versus empagliflozin (EMPA) to improve glycemic control in people with Chronic Pancreatitis (CP) or Recurrent Acute Pancreatitis (RAP) associated with Diabetes Mellitus (DM). To evaluate mixed meal response in PIO versus EMPA group to better understand physiology of both therapies in CP-DM.

Study Overview

Detailed Description

This trial will test the efficacy of PIO versus EMPA in improving glycemic control in CP-DM. The anticipated enrollment will consist of 40 subjects, age 18-80 years who have been diagnosed with CP or RAP with DM, at two clinical sites in the United States. The primary objective is to evaluate the efficacy of PIO vs. EMPA to improve glycemic control in people with CP or RAP associated with DM.

Patients will be willing to safely withdraw one or more study medication or mealtime insulin under the supervision of the study team by the time of screening. The patients clinical team will be informed promptly. Patients not on any antihyperglycemic medications are also eligible.

    a. If on a GLP-1 medication (e.g., semaglutide [Ozempic, Wegovy, Rybelsus], liraglutide, dulaglutide, exenatide, tirzepatide, etc.), the patient must be on a stable dose for at least 3 months prior to enrollment, with stable weight status at the time of enrollment and the GLP-1 dose cannot be escalated during the study period.

  13. Active alcohol dependence or chemical dependence including tobacco based on investigator discretion
  14. On a ketogenic diet
  15. Autoimmune pancreatitis, obstructive pancreatitis, and prior surgery of pancreas (Whipple procedure, total pancreatectomy, and distal pancreatectomy)

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Pioglitazone (PIO)
PIO (Actos) is a thiazolidinedione and an agonist for peroxisome proliferator activated receptor (PPAR) gamma indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 DM in multiple clinical settings. Its use has limitation for type 1 DM or for treatment of diabetic ketoacidosis. It is contraindicated to use in established NYHA class III or IV heart failure.
Subjects will take 30 mg tablet, once daily in the morning, taken with or without food for 12 weeks and after 12 weeks dose will be escalated to 45 mg based on Hemoglobin A1c (HbA1c) levels (HbA1c >7.0% at 12 weeks, escalate the dose) once daily in the morning, taken with or without food till 24 weeks.
Experimental: Empagliflozin (EMPA)
EMPA is a sodium-glucose co-transporter 2 inhibitor, FDA approved drug. It is indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in adults with heart failure, to reduce the risk of cardiovascular death in adults with type 2 DM and established cardiovascular disease and as an adjunct to diet and exercise to improve glycemic control in adults with type 2 DM. It is not recommended in patients with type 1 DM. It may increase the risk of diabetic ketoacidosis. Not recommended for use to improve glycemic control in adults with type 2 DM with an eGFR less than 30mL/min/1.73m2.
Subjects will start with 10 mg dose, once daily in the morning, taken with or without food for 12 weeks and after 12 weeks dose will be escalated to 25 mg based on Hemoglobin A1c (HbA1c) levels (HbA1c >7.0% at 12 weeks, escalate the dose) once daily in the morning, taken with or without food.

Patient-Reported Outcomes Measurement Information System - 29 Profile v2.1 (PROMIS-29 Profile v2.1)
Time Frame: Baseline to 24 weeks

The PROMIS-29 Profile assesses following domains:

  • Physical function
  • Pain interference
  • Anxiety
  • Depression
  • Fatigue
  • Sleep disturbance
  • Ability to participate in social roles and activities

PROMIS-29 is scored using T-scores. Higher T-scores indicate a higher level of the underlying construct.

Each domain has a set of questions, typically 4 to 6 items, and responses are rated on a 5-point Likert scale (e.g., "Never," "Rarely," "Sometimes," "Often," "Always" or "Not at all," "A little bit," "Somewhat," etc.). The responses are then scored on a T-score scale (with a mean of 50 and a standard deviation of 10 in the general population).

T-scores Interpretation:

  • A T-score of 50 is the average score for the general population.
  • T-scores above 50 indicate better functioning or less severe symptoms.
  • T-scores below 50 indicate worse functioning or more severe symptoms.
