Study Description

Brief Summary:

The purpose of this study is to evaluate the safety and efficacy of adipose derived cells for the treatment of erectile dysfunction symptoms.

Condition or disease	Intervention/treatment	Phase
Erectile Dysfunction	Device: Tissue Genesis Cell Isolation System	Not Applicable

Detailed Description:

This trial is being conducted to determine the safety and efficacy of injecting autologous adipose derived cells into the penis of men with erectile dysfunction. Subjects will be randomized into a treatment and control arm.

6. Not interested or able to use oral PDE-5 inhibitor (PDE-5i) drug therapy, and willing to forgo these treatments for the first 6-month period following study treatment (in addition may include a minimum 4-week washout since last PDE-5i use prior to completion of the baseline erectile function assessments and study treatment)
7. Willing to limit alcohol intake and eliminate use of recreational drugs for sexual encounters
8. Willing to undergo a minor surgical procedure and injection
9. Abdominal area amenable to liposuction of at least 60-120 cc of adipose tissue based on Investigator examination
10. Mentally competent and able to understand all study requirements (based on investigator assessment)
11. Willing to be available for all baseline, treatment and follow-up examinations required by protocol
12. Willing to forego participation in any other study throughout the duration of this study unless receiving prior approval by Sponsor.

Exclusion Criteria:

1. Evidence of prostate cancer which requires additional radiotherapy or other adjuvant therapy
2. Previous pelvic or abdominal radiation therapy
3. Previous, concomitant or scheduled use of anti-androgen therapy
4. Untreated hypogonadism or low serum total testosterone (< 200 ng/dL)
5. Clinically evident penile anatomical deformities (e.g., Peyronie's disease) or history of priapism
6. Skin irritation, infection, wound, sore or disruption in the immediate areas of skin entry for abdominal liposuction or penile injection (including abdominal trauma and abdominal skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma))
7. Use of any non-study treatment for erectile dysfunction within 4 weeks of study treatment and a lack of willingness to continue through 6 months after study treatment
8. Any previous penile implant or penile vascular surgery
9. Current or previous malignancy other than localized prostate cancer or nonabdominal, non-melanoma skin cancer (successfully treated or treatable by curative excision or other local curative therapy- abdominal skin cancer is exclusionary as indicated in criteria 6)
10. Uncontrolled hypertension or hypotension (systolic blood pressure > 170 or < 90 mm Hg, and diastolic blood pressure > 100 or < 50 mm Hg)
11. Reported unstable cardiovascular disease (e.g., unstable angina, myocardial infarction within past 6 months, cardiac failure or life-threatening arrhythmia, congestive heart failure) or symptomatic postural hypotension within 6 months before screening
12. Hemoglobin A1c > 8% within 8 weeks prior to study treatment
13. Current urinary tract or bladder infection
14. Drug, alcohol, or substance abuse reported within the last three years (subject reported)
15. Subject's sexual partner is < 18 years of age, nursing, or known to be pregnant at screening, or wishes to become pregnant during the study period, or has any gynecologic problems, major medical conditions, or other factors that would limit participation in sexual intercourse to less than 4 times per month (subject reported)
