Brief Summary

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

The aim of the study is to evaluate in adult subjects with resistant depression the effect of an injection of botulinum toxin in the corrugator and procerus muscles, in comparison to the infiltration of the crow's feet area, in addition to the current antidepressant treatment.

Detailed Description

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

Three randomized, double-blind, placebo-controlled studies have shown that a single injection of OnaBotulinum Toxin A (OnaA) into the corrugator and procerus (frowning muscles) allows for a significant decrease in patients with a depressive episode characterized resistant.

However, the effectiveness of this method of treating depression can not currently be considered established.

The main objective of our study is therefore to evaluate the efficacy of OnaA injections in the glabellar zone with a different methodology, using lateral muscle injection orbicularis oculi (involved in crow's feet wrinkles). ) as another injection zone in comparison.

The efficacy will correspond to the number of responders at 6 weeks in the two groups of injection.

This evaluation will be done at 6 weeks, then at 3 months (S12).

Intervention Model

PARALLEL

The main pitfall of these studies is indeed the difficulty in ensuring a double-blind when the TB is injected into the corrugator and the procerus with placebo as physiological saline, since the patient as the examiner can guess which product was administered.

The main objective of our study is therefore to evaluate the efficacy of OnaA injections in the glabellar zone , using lateral muscle injection orbicularis oculi (involved in crow's feet wrinkles) as another injection zone in comparison.
