GLP-1 Agonists for Prevention of Recurrent Hypertriglyceridemic Acute Pancreatitis (RECAP-GLP1)

May 28, 2026 updated by: DONG WU, Peking Union Medical College Hospital

Effects of GLP-1 Agonists on Prevention of HTG-Induced Acute Pancreatitis Recurrence: Protocol for a Randomized Clinical Trial

Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is associated with a high risk of recurrence despite standard lipid-lowering therapy and lifestyle modification. The goal of this clinical trial is to evaluate whether GLP-1 receptor agonist therapy can reduce the recurrence of HTG-AP in adults with a history of HTG-AP and hypertriglyceridemia.

The main questions this study aims to answer are:

  • Whether GLP-1 receptor agonist therapy reduces the recurrence rate of HTG-AP.
  • Whether GLP-1 receptor agonist therapy improves triglyceride control, body weight, and metabolic parameters.
  • Whether GLP-1 receptor agonist therapy is safe and well tolerated in this patient population.

Researchers will compare GLP-1 receptor agonist therapy plus standard care with standard care alone to determine whether GLP-1 receptor agonist therapy provides additional benefit in preventing recurrent HTG-AP.

Participants will:

  • Receive either GLP-1 receptor agonist therapy plus standard care or standard care alone.
  • Undergo regular clinical follow-up visits and laboratory assessments.
  • Receive monitoring of triglyceride levels, recurrence events, metabolic outcomes, and adverse events during the study period.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Semaglutide
Participants receive once-weekly subcutaneous semaglutide for 18 months. Semaglutide is initiated at 0.25 mg weekly for 4 weeks and escalated to 0.5 mg weekly thereafter. Participants also receive standard-of-care management and lifestyle modification counseling, including low-fat diet, physical activity, weight management, smoking cessation, and alcohol limitation.
Semaglutide is administered as a once-weekly subcutaneous injection for 18 months. Treatment is initiated at 0.25 mg once weekly for the first 4 weeks and escalated to 0.5 mg once weekly thereafter to improve tolerability.
Other Names:
  • Ozempic
  • Wegovy
Placebo Comparator: Placebo
Participants receive once-weekly matching placebo (normal saline) subcutaneous injections for 18 months following the same administration schedule as the experimental arm. Participants also receive standard-of-care management and lifestyle modification counseling, including low-fat diet, physical activity, weight management, smoking cessation, and alcohol limitation.
Placebo consists of normal saline administered as a once-weekly subcutaneous injection following the same administration schedule as semaglutide for 18 months. Participants receive 0.25 mg-equivalent injection volume once weekly for the first 4 weeks followed by 0.5 mg-equivalent injection volume once weekly thereafter.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of participants with recurrent hypertriglyceridemia-induced acute pancreatitis
Time Frame: Within 18 months after randomization
Recurrent hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is defined as an episode of acute pancreatitis occurring at least 1 month after complete symptom resolution from the index episode, with serum triglycerides >1000 mg/dL or triglycerides 500-1000 mg/dL accompanied by chylous serum and no other identifiable cause of acute pancreatitis.
Within 18 months after randomization

Secondary Outcome Measures

Time Frame: 18 months after randomization
Total number of recurrent HTG-AP episodes experienced by each participant during follow-up.
18 months after randomization
