Brief summary
The proposed project is focused towards evaluation of Pirfenidone as a novel therapeutic strategy in patients with chronic pancreatitis (CP).
Detailed description
This is a multi-institutional, double-blind, placebo-controlled clinical trial of the safety, tolerability and efficacy of Pirfenidone in patients with CP. Patients with a confirmed diagnosis of CP will be randomly assigned to Pirfenidone or placebo (2:1 randomization). The assigned allocation (drug or placebo) will be continued for 48 weeks. Subjects will be asked to complete questionnaires, have blood draws, and will be randomized to either the IP or placebo. They will have both in person and telephone/remote visits.
Interventions
Oral tablets taken with food three times daily. Titrated over 14 days: one tablet three times daily in week 1, two tablets three times daily in week 2, and three tablets three times daily (801 mg three times daily) from week 3 onward. Continued for 48 weeks unless reduced or interrupted to manage an adverse event. Dispensed by Investigational Drug Services according to the randomization code.
Matching placebo tablets, identical in appearance and packaging to the pirfenidone tablets to maintain double blinding. Administered on the same schedule: one tablet three times daily in week 1, two in week 2, and three from week 3 onward, taken with food, for a total of 48 weeks. Dispensed by Investigational Drug Services according to the randomization code.
Patient-reported outcome instrument administered to all participants in both arms to assess health-related quality of life. Completed by the participant at Weeks 0, 4, 12, 24, 36, 48, 60, 72, 84 and 96, and at Early Termination.
Patient-reported outcome instrument administered to all participants in both arms to assess perceived pain. Completed by the participant at Weeks 0, 4, 12, 24, 36, 48, 60, 72, 84 and 96, and at Early Termination.
Patient-reported outcome instrument administered to all participants in both arms. Administered once per visit and used for two purposes: the pain severity items assess perceived pain, and the pain interference items assess ability to participate in social roles and activities. Completed by the participant at Weeks 0, 4, 12, 24, 36, 48, 60, 72, 84 and 96, and at Early Termination.

If the patient is able to consult with their prescriber and switch to an alternative medication that is not a CYP1A2 inhibitor, they may be eligible for inclusion in the clinical trial. Any patient who stops a CYP1A2 inhibitor to be enrolled in the clinical trial, we will wait for 7 days or 5 half-lives (whichever is longer) before the study drug is started. 23. Patients taking strong CYP1A2 inducers, namely Albendazole, Carbamazepine, Primidone and Rifampin, and who cannot stop these drugs safely, will be excluded.

All participants of childbearing potential, except if post-menopausal \[see definition of menopause below\] or had a hysterectomy, bilateral tubal ligation/clip (surgical sterilization) or surgical removal of both the ovaries), must have a negative urine pregnancy test documented within 2 days prior to initiation of the study drug. Menopause can be assumed to have occurred when there is either: A) Either twelve \[12\] months of spontaneous amenorrhea; or B) six \[6\] months of spontaneous amenorrhea with serum FSH levels \> 40 mIU/mL; or C) six \[6\] weeks postsurgical bilateral oophorectomy with or without hysterectomy. Hormonal deficiency will be documented in the case of suspected spontaneous menopause as follows: 1. If age \>54 years and with the absence of normal menses: Serum FSH (Follicle Stimulating Hormone) level elevated to within the post-menopausal range based on the laboratory reference range where the hormonal assay is performed; 2. If age \<54 years and with the absence of normal menses: Negative serum or urine -Human Chorionic Gonadotropin (HCG) with concurrently elevated serum FSH (Follicle Stimulating Hormone) level in the post-menopausal range, depressed estradiol (E2) level in the post-menopausal range, and absent serum progesterone level, based on the laboratory reference ranges where the hormonal assays are performed
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With at Least One Grade 3 or Grade 4 Adverse Event as Assessed by CTCAE Version 5.0 | From first dose of study drug through Week 48 | Adverse events will be assessed and graded using a modified Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, which grades events from Grade 1, mild, to Grade 5, death related to adverse event. A participant is counted once if one or more adverse events of Grade 3 or Grade 4 are recorded during the treatment period, regardless of how many such events occur. The proportion of participants meeting this criterion will be compared between the pirfenidone and placebo arms. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of Pancreatitis-Related Emergency Room Visits Not Requiring Hospital Admission Per Participant-Year | From randomization through Week 96 | : The total number of emergency room visits attributed to pancreatitis, comprising visits for pancreatic pain, for episodes of acute pancreatitis, or for pancreatitis-related complications, that did not result in hospital admission, divided by the total participant-years of follow-up. Reported as events per participant-year; higher values indicate more frequent visits. |
| Rate of Pancreatitis-Related Hospital Admissions Per Participant-Year | From randomization through Week 96 | The total number of hospital admissions attributed to pancreatitis, comprising admissions for pancreatic pain, for episodes of acute pancreatitis, or for pancreatitis-related complications, divided by the total participant-years of follow-up. Reported as events per participant-year; higher values indicate more frequent admissions. |
| Number of Participants With at Least One Documented Episode of Acute Pancreatitis | From randomization through Week 96 | An episode of acute pancreatitis is documented by amylase or lipase elevation of two times or more the upper limit of normal, by findings of pancreatic inflammation on cross-sectional imaging, or by clinical diagnosis alone. Episodes are counted whether or not they result in an emergency room visit or hospital admission. A participant is counted once if one or more such episodes occur. |
| Mean Change From Baseline in PROMIS Global Health Global Physical Health T-Score | Baseline (Week 0), Week 48, and Week 96 | The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health short form is self-completed by the participant. Global Physical Health raw scores are converted to a T-score calibrated so that the United States general population has a mean of 50 and a standard deviation of 10. Higher scores indicate better physical health. |
| Mean Change From Baseline in PROMIS Global Health Global Mental Health T-Score | Baseline (Week 0), Week 48, and Week 96 | The Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health short form is self-completed by the participant. Global Mental Health raw scores are converted to a T-score calibrated so that the United States general population has a mean of 50 and a standard deviation of 10. Higher scores indicate better mental health. |
| Mean Change From Baseline in Comprehensive Pain Assessment Tool Short Form (COMPAT-SF) Total Score | Baseline (Week 0), Week 48, and Week 96 | The Comprehensive Pain Assessment Tool Short Form is a pancreatitis-specific multidimensional pain instrument self-completed by the participant. Higher scores indicate greater pain burden. |
| Mean Change From Baseline in Brief Pain Inventory Pain Severity Score | Baseline (Week 0), Week 48, and Week 96 | The Brief Pain Inventory is self-completed by the participant. The four pain severity items are each scored from 0, no pain, to 10, pain as bad as you can imagine, and are averaged to produce a severity score ranging from 0 to 10. Higher scores indicate greater pain severity. |
| Mean Change From Baseline in PANQOLI Role Function Subscale Score | Baseline (Week 0), Week 48, and Week 96 | The role function subscale of the Pancreatitis Quality of Life Instrument (PANQOLI) is self-completed by the participant. |
| Mean Change From Baseline in Opioid Use Measured in Morphine Milligram Equivalents | The 30 days preceding Baseline (Week 0), Week 48, and Week 96 | Opioid dispensing records are obtained from the Prescription Drug Monitoring Program with participant consent and are complemented by participant-reported intake. Total opioid consumption over the 30 days preceding each assessment is converted to morphine milligram equivalents using established conversion factors. Higher values indicate greater opioid use. |
| Number of Participants With a New Diagnosis of Pancreatic Endocrine Dysfunction | Baseline (Week 0), Week 48, and Week 96 | Endocrine status is determined by hemoglobin A1c and by fasting or random blood glucose, interpreted by the investigator. A new diagnosis is recorded where the investigator determines that endocrine dysfunction is present at an assessment timepoint in a participant who did not have a diagnosis of diabetes at Week 0. A participant is counted once. |
| Number of Participants With a New Diagnosis of Pancreatic Exocrine Dysfunction | Within 2 months after first dose of study drug, at Week 48, and at Week 96 | Exocrine status is determined by fecal elastase measured on a participant-collected stool specimen. A new diagnosis is recorded where the investigator determines that exocrine insufficiency is present at an assessment timepoint in a participant who did not have exocrine insufficiency at the first timepoint. A participant is counted once. |
