A Clinical Study of FT1 in Patients With Short Bowel Syndrome

Официальное название

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

Обзор

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.

Подробное описание

In this placebo-controlled, double-blind, randomized, crossover phase 2 trial, 8 adult SBS patients are treated with once-weekly FT1 or placebo (1:1) for 5 weeks, followed by a washout period of at least 6 weeks, and then the alternate treatment for a further 5 weeks.

Efficacy is evaluated through a 72 hour metabolic balance study conducted at baseline and at the end of each treatment cycle.
