Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • To evaluate the occurrence of clinical adverse event (tolerance) to intracavernous injection of autologous MSC in patients 18 to 50 years of age with complicated type 1 diabetes mellitus with erectile dysfunction refractory to oral treatment.

    Occurrence within 2 weeks after the injection of CSMa at the expected dose (10.106, 20.106, 30.106 and 40.106) of a clinical adverse event: thrombosis (s) of the cavernous body, subcutaneous hematoma, induration of the cavernous body , local inflammatory reaction (redness, pain), general effects: fever, chills

    within 2 weeks after the injection of CSMa

Secondary Outcomes (10)

  • Evaluation of the efficacy of autologous MSC intracavernous injections at different doses with evaluation of the clinical score IIEF-5 (International Index of Erectile Function-5)

    12 and 24 weeks after injection

  • Evaluation of the efficacy of autologous MSC intracavernous injections at different doses with evaluation of the EHS score

    12 and 24 weeks after injection

  • Evaluation of the efficacy of autologous MSC intracavernous injections at different doses with evaluation of arterial insufficiency

    12 and 24 weeks after injection

  • Evaluation of the efficacy of autologous MSC intracavernous injections at different doses with evaluation of venous insufficiency (venous leakage)

    12 and 24 weeks after injection

  • Evaluation of the feasibility of the autologous MSC intracavernous injection protocol by the number of bone marrow extraction

    19 months

  • +5 more secondary outcomes
