Brief Summary:
This clinical study is designed to investigate the safety and potential ability of relocated autologous SVF (stromal vascular fraction) to restore erectile function in men with ED (erectile dysfunction).

Condition or disease Intervention/treatment Phase
Erectile Dysfunction Device: Injection of adipose derived cells into penis Not Applicable

Detailed Description:

Prospective, multi-center, two-arm, blinded, randomized treatment. Covariate adaptive randomization will be used. Covariates included in the adaptive randomization process will be investigational center, history of diabetes, and radical prostatectomy. The two randomized study arms are:

  1. Treatment with SVF followed six months later with sham treatment (ARM 1)
  2. Sham treatment followed six months later by treatment with SVF (ARM 2) Study population is 60 adult male subjects with organic erectile dysfunction (IIEF-EF score 11-22) of greater than 6 months' duration due to radical prostatectomy, diabetes mellitus, and/or vascular disease. Subjects will be followed for 12 months after initial treatment.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Prospective, multi-center, two-arm, blinded, randomized treatment. Covariate adaptive randomization will be used. Covariates included in the adaptive randomization process will be investigational center, history of diabetes, and radical prostatectomy.
Masking: Single (Participant)
Masking Description: Sham treatment
Primary Purpose: Treatment
Official Title: Evaluation of the Tissue Genesis Icellator Cell Isolation System to Treat Erectile Dysfunction
Estimated Study Start Date : September 1, 2018
Estimated Primary Completion Date : September 1, 2019
Estimated Study Completion Date : September 1, 2020

Arm Intervention/treatment
Experimental: ARM 1
Injection of adipose derived cells into penis followed six months later with sham control saline injection procedure
Device: Injection of adipose derived cells into penis
Injection of Icellator-derived cells
Other Name: Sham control intervention of injection of saline into penis

Experimental: ARM 2
Sham control saline injection procedure followed six months later by injection of adipose derived cells into penis
Device: Injection of adipose derived cells into penis
Injection of Icellator-derived cells
Other Name: Sham control intervention of injection of saline into penis




Primary Outcome Measures :
  1. Primary Efficacy Objective: ability of adipose derived cells to restore erectile function using the 6-Item IIEF-EF score [ Time Frame: 6 months ]
    Evaluate the ability of adipose derived cells to restore erectile function at 6 months using the 6-Item IIEF-EF score


Secondary Outcome Measures :
  1. Safety Objective: assessment of any adverse events [ Time Frame: 12 months ]
    Will be evaluated by the IDMC through assessment of any adverse events that occur during or after adipose tissue harvest and intracorporal injection of adipose derived cells through 12-month follow-up. All adverse events will be reviewed by the IDMC and the Sponsor at least every 3 months throughout enrollment, and at least annually throughout study follow-up.

Criteria

Inclusion Criteria:

  • Willing and able to provide written informed consent
  • Chronic, organic ED, duration at least 0.5 years, with baseline IIEF-EF score of 11-22
  • Willing to complete a 6-item erectile function questionnaire (IIEF-EF), a 4-week diary of sexual encounters (a single-item erection hardness assessment (EHS) and SEP-2 and SEP-3), 3 erectile function treatment Global Assessment Questions (GAQs), and 3 continence questions within 8 weeks before study treatment (baseline- except GAQs), and at each of the follow-up time points: 6 weeks (excluding EHS, SEP-2, SEP-3, and NPT), and 3, 6, 9, and 12 months after study treatment/ randomization
  • Involved in a monogamous, heterosexual relationship for at least 3 months with both partners motivated to have or attempt sexual intercourse at least 4 times per month beginning two weeks after study treatment (subject reported)
  • Willing to limit alcohol intake and eliminate use of recreational drugs for sexual encounters
  • Willing to undergo two minor surgical procedure (small-volume liposuction, totaling approximately 60 - 120 cc) and two treatments of an injection of up to 30 cc of autologous SVF (or saline) into the corpora cavernosa over a 2- to 4-minute period, with a compression band applied at the base of the penis for total duration of up to 15 minutes
  • Abdominal area amenable to two liposuction of at least 60-120 cc each of adipose tissue based on Investigator examination
  • Mentally competent and able to understand all study requirements (based on investigator assessment)
  • Willing to be available for all baseline, treatment and follow-up examinations required by protocol
  • Willing to forego participation in any other study throughout the duration of this study unless receiving prior approval by Sponsor.

Exclusion Criteria:

  • Evidence of prostate cancer which requires additional radiotherapy or other adjuvant therapy, or PSA > 0 after radical prostatectomy
  • Previous pelvic or abdominal radiation therapy
  • Anti-androgen therapy within the last 12 months or anti-androgen therapy of greater than 6 months in duration
  • Untreated hypogonadism or low serum total testosterone (< 300 ng/dL)
  • Clinically evident penile anatomical deformities (e.g., Peyronie's disease) or history of priapism
  • 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)
  • Any previous penile implant or penile vascular surgery
  • Current or previous malignancy other than localized prostate cancer or non-abdominal, non-melanoma skin cancer (successfully treated or treatable by curative excision or other local curative therapy- abdominal skin cancer is exclusionary)
  • Uncontrolled hypertension or hypotension (systolic blood pressure > 170 or < 90 mm Hg, and diastolic blood pressure > 100 or < 50 mm Hg)
