About this trial

Autoimmune pancreatitis (AIP) is an autoimmune disease with low incidence rate and involving the pancreas. In China, type I AIP is predominant. Glucocorticoids (GC) have a significant therapeutic effect. Even though a consensus has been reached on the effective initial GC treatment dose, type I AIP is prone to recurrence after GC induction and maintenance therapy. Currently, there is no consensus on how to reduce the disease recurrence rate in high-risk type I AIP patients. Multiple studies have shown that immunosuppressants (IM) combined with GC can effectively reduce the disease recurrence rate in IgG4 RD patients, including azathioprine, mycophenolate mofetil (MMF), etc. Among them, the incidence of adverse reactions in MMF is relatively low. As a special type of IgG4-RD, there is currently no prospective study evaluating the efficacy and safety of GC combined with MMF treatment in high-risk recurrent type I AIP patients. The smooth implementation of this project can provide new treatment ideas and evidence-based medicine for reducing the recurrence rate of high-risk type I AIP.

Treatments tested in this trial

  • Glucocorticoids

    Drug

    The study subjects were randomly divided into a GC monotherapy maintenance group and a GC combined with MMF maintenance group in a 1:1 ratio. The randomization sequence was generated online using a computer randomization scheme. Group A was the GC monotherapy maintenance group

  • Glucocorticoids+MMF

    Drug

    The study subjects were randomly divided into a GC monotherapy maintenance group and a GC combined with MMF maintenance group in a 1:1 ratio. The randomization sequence was generated online using a computer randomization scheme. Group B was the GC+MMF maintenance group

Trial outcomes

Primary outcomes

1

Disease remission rate within 3 years in high-risk type I AIP patients receiving glucocorticoid monotherapy versus glucocorticoid combined with MMF maintenance therapy

Disease remission is defined as the proportion of patients achieving complete or partial resolution of clinical symptoms, normalization or significant improvement of imaging findings, and reduction of serum IgG4 levels. Remission rate will be compared between the glucocorticoid monotherapy group and the glucocorticoid plus MMF combination therapy group within 3 years of follow-up.

Time frame
3 years
2

Disease remission rate within 1 years in high-risk type I AIP patients receiving glucocorticoid monotherapy versus glucocorticoid combined with MMF maintenance therapy

Disease remission is defined as the proportion of patients achieving complete or partial resolution of clinical symptoms, normalization or significant improvement of imaging findings, and reduction of serum IgG4 levels. Remission rate will be compared between the glucocorticoid monotherapy group and the glucocorticoid plus MMF combination therapy group within 1 years of follow-up.

Time frame
1 year

Secondary outcomes

1

Changes in endocrine function

Endocrine function will be assessed by the following measures: (1) incidence of new-onset diabetes mellitus during the 3-year follow-up period; (2) change from baseline in HbA1c levels; (3) change from baseline in C-peptide levels; (4) change from baseline in insulin secretion capacity.

Time frame
3 years
2

Changes in external secretion pancreatic function

Pancreatic exocrine function will be assessed by the following measures: (1) incidence of pancreatic exocrine insufficiency during the 3-year follow-up period; (2) change from baseline in serum vitamin levels (including vitamin A, D, E); (3) change from baseline in serum 25-OH-D3 levels.

Time frame
3 years
3

Incidence of malignant tumors

Incidence of newly diagnosed malignant tumors, specifically gastrointestinal tumors (including esophageal, gastric, pancreatic, and colorectal tumors), detected by endoscopic examination during the 3-year follow-up period. All tumor diagnoses will be confirmed by histopathological evaluation.

Time frame
3 years
