Brief Summary:
This phase I clinical trial is designed to evaluate the safety of autologous Mesenchymal Stem Cells (MSC) injected intracavernously.

Condition or disease Intervention/treatment Phase
Erectile Dysfunction Drug: mesenchymal stem cell Phase 1

Detailed Description:
Cellgram-ED is autologous bone marrow-derived mesenchymal stem cells ex vivo expanded for approximately 30 days. Ten patients (Diabetes -associated ED; 5 patients, Postprostatectomy; 5patients) will be injected Cellgram-ED directly into the intracavernous. Patient will be evaluated the safety and potential efficacy of MSC.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 10 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open, Single-center, Phase 1 Study to Evaluate Safety of Autologous Bone Marrow Derived Mesenchymal Stem Cell in Erectile Dysfunction.
Study Start Date : July 2015
Actual Primary Completion Date : January 31, 2018
Actual Study Completion Date : April 2018

Arm Intervention/treatment
Experimental: Mesenchymal stem cell
Patients will receive single intracavernous injection of Mesenchymal stem cell. Oral PDE5-inhibitor can take on demand.
Drug: mesenchymal stem cell
Patients will receive single injection of Cellgram-ED( 30,000,000 mesenchymal stem cell) intracavernously.
Other Name: Cellgram-ED




Primary Outcome Measures :
  1. Number and severity of adverse events [ Time Frame: 12month ]
    Analyze the laboratory, vital sign, physical exam results from baseline to end of the study for investigate adverse reactions and view safety.


Secondary Outcome Measures :
  1. Change From Baseline in the International Index of Erectile Function(IIEF) [ Time Frame: month 1, 3, 6, 9 and 12 ]
    Description of the average variation from the screening value in each group using the Student's preordered t-test (Wilcoxon's signed bank test).

  2. Penile Duplex Ultrasonography [ Time Frame: month 6, 12 ]
    Change From Baseline in Peak systolic velocity (PSV) and End diastolic velocity (EDV)

  3. Change From Baseline in Sexual Encounter Profile (SEP) Question 2 [ Time Frame: month 1, 3, 6, 9 and 12 ]
    The SEP2 survey describes cumulative success rates for 30 days, 3 months, 6 months, 9 months and 12 months after cell treatment.

  4. Global Assessment Question (GAQ) [ Time Frame: month 1, 3, 6, 9 and 12 ]
    The GAQ survey describes cumulative success rates for 30 days, 3 months, 6 months, 9 months and 12 months after cell treatment.
