Dapiglutide for the Treatment of Obesity — DREAM  

Obesity Clinical Trial

Official title: Dapiglutide for the Treatment of Obesity (DREAM): a Randomised, Double-blind, Placebo-controlled, Investigator-initiated Trial

Status Active, not recruiting

Clinical Trial Summary

This study is an investigator-initiated, proof-of-concept, randomised, double-blind, placebo-controlled, parallel-group, single-centre clinical trial investigating the body weight loss potential of dapiglutide, a dual GLP-1R/GLP-2R agonist, administered subcutaneously once weekly. The study will investigate the efficacy of once-weekly subcutaneously administered of 4 mg and 6 mg dapiglutide versus placebo in 54 obese individuals (BMI >30 kg/m2) during a 12-week treatment period.

Clinical Trial Description

In total, 54 obese participants with a body mass index (BMI) of ≥ 30 kg/m² are randomised to either treatment with the investigational medicinal product (IMP), being either dapiglutide 4 mg, dapiglutide 6 mg, or placebo for 12 weeks. To ensure blinding, the placebo arm is split between 4 mg and 6 mg placebo, making the randomisation sequence 2:2:1:1. The trial encompasses a 3-week screening period containing a screening visit (V1) to assess eligibility, followed by a randomisation visit (V2) and subsequently a 12-week treatment period concluded with a 4-week follow-up period. The IMP is subcutaneously administered in the abdomen once weekly from week 0 (V2) until week 12 (V14). The IMP is initiated at 2 mg once-weekly and up-titrated every third week with 2 mg until the respective trial doses are reached in each arm. Hereafter, the participants are kept at the dose level for the remainder of the trial (from week 3 and week 6 for the 4 mg and 6 mg doses, respectively). To reduce dropout in cases of low tolerability of the IMP, the investigator can postpone up-titration or down-titrate if judged necessary for participant retention or safety. The trial schedule will consist of five on-site visits, including screening, randomisation and a safety follow-up visit (four weeks after end of treatment (EOT)), in addition to a minimum of 10 telephone consultations. Therefore, the maximum trial duration is 16 weeks. For exploratory purposes, participants are invited to participate in a gastroduodenoscopy sub-study obtaining gastric and duodenal biopsies before and after treatment with IMP. A maximum of 7 participants from each treatment arm (total n=21) participate in this sub-study. ;
