Safety and Tolerability of Pirfenidone in Acute Pancreatitis
Purpose
The goal of the current pilot clinical trial is to evaluate the safety and tolerability of pirfenidone in patients with predicted moderately severe and severe acute pancreatitis. Pirfenidone is currently approved by FDA for the treatment of idiopathic pulmonary fibrosis. Now, over 5 years of data has accumulated demonstrating safety of its use in humans. The investigators' preclinical data suggest that pirfenidone is very effective in reducing the severity of acute pancreatitis in animal models. Following are the objectives of the proposed clinical trial: Primary Objective: - To evaluate the safety and tolerability of pirfenidone, compared to placebo, in patients predicted to have moderately severe or severe AP. - To evaluate the efficacy of pirfenidone in reducing the laboratory markers of inflammation and improving patient reported outcome measures. Secondary Objective: - To evaluate the efficacy of pirfenidone in reducing the severity of acute pancreatitis, as measured by well-defined endpoints.

Advanced liver disease 14. Paralytic ileus or significant nausea and vomiting 15. Chronic Diarrhea 16. Immunosuppressive disorder or on immunosuppressive medications 17. Active or advanced malignancy 18. Known cancer that is end-stage with ongoing palliative care or for which palliative care is appropriate 19. Known established infection prior to the onset of acute pancreatitis 20. Known history of infective hepatitis 21. Known live vaccines or therapeutic infectious agents within one month of admission 22. Known pregnancy or lactation at the time of admission 23. Ongoing photosensitivity and rash 24. Women of childbearing potential who are not on oral or injectable contraceptives or IUDs and do not consent to practice abstinence for period of 4 weeks. 25. Known to be currently participating in a trial testing any investigational medicinal product or participation in a clinical study involving a medicinal product in the last three months 26.

Detailed Description
The study is a Randomized Pilot clinical trial evaluating safety and tolerability of pirfenidone in patients with predicted moderately severe to severe acute pancreatitis. There are built in secondary end-points for efficacy. The patients with acute pancreatitis, who present within 48h of establishment of the diagnosis, will be screened for exclusion and inclusion criteria and consented for the clinical trial. Patients with be randomized into placebo or pirfenidone arm and followed daily in-person, while in hospital, and by telephone once discharged from the hospital (weekly for 4 weeks, then monthly for up to 6 months) for study end points.
