Anti-inflammatory Therapy to Improve Outcomes After TPIAT
Anti-inflammatory Therapy to Improve Outcomes in Patients With Chronic Pancreatitis Undergoing Total Pancreatectomy Islet Autotransplantation
Source: ClinicalTrials.gov · Last updated 9 Jun 2026
Brief summary (registry, in English)
Patients with severe chronic pancreatitis may be candidates to have their pancreas removed and their islets transplanted into the liver to reduce the risk of diabetes mellitus, a procedure called total pancreatectomy with islet autotransplant (TPIAT). However, over half of patients who have a TPIAT will need to remain on some supplemental insulin life-long after the procedure. We will study therapies that may reduce damage to transplanted islets, and thereby improve long-term outcomes. Two promising anti-inflammatory therapies are available to protect islets from damage at the time of transplant: (1) the Tumor Necrosis Factor (TNF)-alpha inhibitor etanercept and (2) the serine protease inhibitor alpha-1 antitrypsin. Both agents are commercially available for clinical trials. Proof-of-principle for etanercept has been demonstrated in type 1 diabetic allotransplant recipients, in whom a 10 day course of etanercept early post-transplant significantly improved long-term insulin independence, due to better survival of the transplanted beta cell mass in the engraftment period. Alpha-1 antitrypsin (A1AT) reduces inflammatory cytokines, protects against cytokine-induced beta cell apoptosis, and prolongs islet graft survival in mice and intraportal IAT non-human primates. This initial 3-arm drug-treatment clinical trial will investigate the use of Etanercept and A1AT to improve IAT function at 90 days and 1 and 2 years post-TPIAT compared to standard care. Forty-five patients undergoing TPIAT will be randomized 1:1:1 to receive either: 1) etanercept (50 mg on day 0; 25 mg on days 3, 7, 10, 14, and 21), 2) alpha-1 antitrypsin (90 mg/kg IV days -1, +3, 7, 14, 21, 28) or 3) standard care. Patients will have mechanistic assessments drawn in the early post-operative period including inflammatory cytokines and chemokines and measures of beta cell loss. Metabolic testing will occur at 90, 365, and 730 days post-TPIAT, including mixed meal tolerance testing, IV glucose tolerance testing, and glucose-potentiated arginine-induced insulin secretion (GPAIS).

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Use of any of the following treatments in the 30 days prior to enrollment: insulin, metformin, sulfonylureas, glinides, thiazolidinediones, Glucagon Like Peptide (GLP)-1 agonists, dipeptidyl peptidase (DPP-4) inhibitors, or amylin.
- History of multiple sclerosis, transverse myelitis, Guillain Barre, or other suspected demyelinating disease, due to risk of exacerbation of these conditions with use of etanercept; or prior history of systemic lupus erythematosus
Other illness
- Known history of human immunodeficiency virus (HIV) infection, hepatitis B (chronic), or hepatitis C (chronic).
- History of tuberculosis (TB) (latent or active disease), or positive TB skin test.
- History of symptomatic fungal lung infection.
- Known hypersensitivity to etanercept or A1AT.
- Any condition that is likely, in the opinion of the patient's medical providers, to necessitate use of TNF alpha therapeutically in the future (such as psoriatic arthritis).
- Known coagulopathy, or need for anticoagulant therapy preoperatively (coumadin, enoxaparin), or any history of pulmonary embolism.
- Untreated psychiatric illness that may interfere with ability to give informed consent, or other developmental delay or neurocognitive disorder that impairs with a patient's ability to consent on their own behalf.
- Any other medical condition that, in the opinion of the investigator, may interfere with the patient's ability to successfully and safely complete the trial.
Lab values
- Pre-existing diagnosis of diabetes mellitus, fasting blood glucose \>115 mg/dl, or hemoglobin A1c level \>6.0% because these are all evidence of inadequate beta-cell mass.
- Immunoglobulin (IgA) deficiency (serum level \<5 mg/dL), which has been associated with hypersensitivity to alpha-1 antitrypsin.
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST)\>2.5 times the upper limit of normal (ULN). Bilirubin \>ULN, unless due to benign diagnosis such as Gilbert's.
- Any of the following hematologic abnormalities: severe anemia (hgb \<10 g/dL), thrombocytopenia (\<150/mm3), or neutropenia (\<1.0 x109/L).
- Current use or expected use of oral or injected corticosteroids, or any mediation likely to affect glucose tolerance. However, use of hydrocortisone for physiologic replacement, or use of any topical, inhaled, or intranasal glucocorticoid is permitted.
Other
- Current or expected use of any other immunosuppressive agent.
- For females, plans to become pregnant or unwillingness to use birth control for the study duration.
- Inability to comply with the study protocol.
Who the study is looking for
- Age 18- 68 years. .
- Scheduled for total pancreatectomy and IAT at University of Minnesota (UM). All patients who are approved for pancreatectomy and IAT at UM are reviewed by a multi-disciplinary committee including surgeons, gastroenterologists specializing in pancreatic disease, a pain specialist, psychologist, and endocrinologist to confirm the diagnosis of chronic pancreatitis and candidate suitability for surgery.
- Able to provide informed consent
