Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This placebo-controlled, double-blind crossover study is to evaluate the GLP-1 analogue dulaglutide regarding changes in sexuality, the mood and the reproductive axis in healthy men.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This placebo-controlled, double-blind crossover study is to evaluate the GLP-1 analogue dulaglutide regarding changes in sexuality, the mood and the reproductive axis in healthy men.

The study consists of following two phases:

* Phase a (V1a-Ev2a): baseline evaluation (V1a), application of the trial medication (dulaglutide or placebo) during 4 weeks (V1a-V4a), evaluation of the primary and secondary outcomes (V2a-V4a, Ev1a), followed by a washout period of at minimum 28 days before evaluation of the last secondary outcome (Ev2a) and cross-over
* Phase b (V1b-Ev2b): baseline evaluation (V1b), application of the trial medication (dulaglutide or placebo) during further 4 weeks (V1b-V4b), evaluation of the primary and secondary outcomes (V2b-V4b, Ev1b), followed by a washout period of at minimum 28 days before evaluation of the last secondary outcome (Ev2b) and study end after study termination visit (STV).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

randomized, double-blind, placebo-controlled trial with crossover design: Dulaglutide or placebo weekly subcutaneously for 4 weeks; in random order, separated by washout period of at minimum 28 days.
Primary Study Purpose

BASIC_SCIENCE

Blinding Strategy

TRIPLE

Participants Caregivers Investigators
Participants, health-care providers and data collectors are blinded to treatment allocation. Excluded from the blinding are defined study nurses administrating the injections as injection devices (dulaglutide/ placebo) are not identical. The unblinded study nurses are otherwise not involved in the trial. During the injection participants are blindfolded such as the injection device and the injection site is not visible for them.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Phase a (V1a-Ev2a): Dulaglutide first- Phase b (V1b-Ev2b) Placebo second

Dulaglutide is injected via pen s.c. once a week. The titration scale will be 1x 1.5mg in 0.5 ml in the first week and 2x 1.5 mg in 2x 0.5 ml once weekly for 3 further weeks. Dulaglutide or placebo weekly subcutaneously for 4 weeks; in random order, separated by washout period of at minimum 28 days.

Group Type EXPERIMENTAL

Dulaglutide

Intervention Type DRUG

Dulaglutide: first week 1x 1.5mg in 0.5 ml, following 3 weeks 2 x 1.5 mg weekly in 0.5ml each, via Pen s.c.

Placebo

Intervention Type DRUG

Placebo: first week 1x0.5 ml physiological saline (0.9% sodium chloride) injection s.c. via syringe, following weeks 2x0.5 ml physiological saline (0.9% sodium chloride) injection s.c. via syringe once weekly for 3 further weeks.

Phase a (V1a-Ev2a): Placebo first- Phase b (V1b-Ev2b) Dulaglutide second

The Placebo will be injected via syringe and contains 0.5ml (only first injection) or 2x0.5ml (second to fourth injection) of 0.9% sodium chloride (0.9% NaCl). Dulaglutide or placebo weekly subcutaneously for 4 weeks; in random order, separated by washout period of at minimum 28 days.
