A Randomized, Double-blind, Crossover, Placebo-controlled Phase IIa Clinical Study Evaluating the Efficacy and Safety of Recombinant Acylated Glucagon Like Peptide-2 Analog (FT1) for Injection in Patients With Short Bowel Syndrome
The goal of this clinical trial is to learn if FT1 is safe and works to treat short bowel syndrome (SBS) in adults. It will also learn about the PK/PD profile of FT1. Researchers will compare FT1 to a placebo (a look-alike substance that contains no drug) to see if FT1 is safe and effective in patients with SBS. Participants will * Receive multiple injections of FT1 or placebo according to weight. * Visit the clinic for assessment.
• Age ≥ 18 years, male or female.
• SBS secondary to surgical resection of the small intestine, screened for at least 12 months after pre intestinal resection surgery;
• Stable weight before screening; For patients requiring parenteral support (PS), PS volume remained stable (with changes in volume or energy content\<25%) within 14 days prior to randomization;
• Willing to undergo colonoscopy and remove polyps assessed by researchers to be at risk of cancer;
• During the trial period, there were no plans to perform any major abdominal surgeries (such as intestinal resection exceeding 10% or surgeries that alter intestinal anatomy, such as stoma surgery);
• During the baseline metabolic balance study, the average daily fecal wet rearrangement amount was ≥ 800g;
