Efficacy and Safety of PJ009 in Patients With Short Bowel Syndrome Requiring Parenteral Nutrition

A Multicenter, Randomized, Double-blind, Placebo-controlled Phase 3 Study to Evaluate the Efficacy and Safety of PJ009 in Patients With Short Bowel Syndrome Requiring Parenteral Nutrition

Sponsor

Chongqing Peg-Bio Biopharm Co., Ltd.

Enrollment

72 participants

Start Date

Sep 3, 2024

Study Type

INTERVENTIONAL

Conditions

Short Bowel Syndrome

Summary

The main aim of this clinical trial is to assess the efficacy and safety of PJ009 in patients aged ≥14 with short bowel syndrome (SBS) requiring parenteral nutrition. The main questions it aims to answer are: * How effective is PJ009 in treating short bowel syndrome? * Is PJ009 safe in these patients? Researchers will compare PJ009 to a placebo (a look-alike substance that contains no drug) to see if PJ009 works to treat SBS. Participants will * Receive daily subcutaneous injections of PJ009 or placebo according to weight for 24 weeks, and then the participants receive placebo will be switched to receive PJ009 for another 12 weeks, while participants receive PJ009 continued the same treatment until the end of 36 weeks, * Visit the clinic at the end of week 1(w1), w2, w4, w8, w12, w16, w20, w24, w30 and w36 for assessment, * Keep a diary of the amount of their parenteral nutrition/ intravenous fluids (PN/IV), enteral nutrition and urine volume.
