Baseline assessment of patients will include completion of 6 questionnaires, EKG (electrocardiogram), vision testing using a standard eye chart, markers of endothelial dysfunction hormone evaluation, laboratory blood tests, vital signs, penile ultrasound (optional), echocardiogram, chest x-ray, and endothelial function assessment (Endopat).
The adipose tissue sample is sent to Celltex's state-of-the-art laboratory in Houston, Texas. For those subjects in the placebo arm, the stem cells will be frozen for later use after one year when the patients cross over into the treatment arm. The subject (patient) will receive an infusion of either autologous stem cells (cells made from his own fat tissue) or placebo every 2 weeks for 3 months. Placebo will be in the form of normal saline. Subjects will be closely monitored every two weeks for first 3 months and once the treatment is complete, subjects will be monitored every 3 months for the first year. Each of the previously mentioned tests will be performed at the 3, 6, 9, and 12 month mark. However, the penile ultrasound (optional) and the echocardiogram will be performed only at the 3 and 12 month mark.
