Brief Summary

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

Diabetes is a major concern in public health because of its high frequency and its negative consequences. Erectile dysfunction (ED) is present, regardless of age, in 50 to 75% of men with diabetes. It is related to endothelial dysfunction and a decrease in smooth muscle and nerve cells. In type 1 diabetic patients, ED is part of the chronic complications of microangiopathy. Current therapies are exclusively symptomatic with moderate efficacy, estimated between 44 and 56%. The administration of culture-grown medullary mesenchymal stem cells (MSCs) would be a curative treatment and have the advantage of being single injection.

However, the data in the literature do not allow to define the optimal dose of MSC in this indication. In addition, the feasibility of this procedure is not known at present.

The aim of this study is to evaluate the tolerance and the efficacy of intracavernous injection of autologous MSC (bone marrow-derived MSCs) administered in a 4-dose-escalating design in patients from 18 to 50 years old with complicated type 1 diabetes mellitus and erectile dysfunction.
