Brief Summary:
This clinical trial will explore the safety and effect of GCSF-mobilized autologous ex vivo selected CD34 cells for the treatment of CMD in adults currently experiencing angina and with no obstructive coronary artery disease. Eligible subjects will receive a single intracoronary infusion of CLBS16.

Primary Outcome Measures :
  1. Change From Baseline in Coronary Flow Reserve [ Time Frame: Day 180 ]
    Coronary Flow Reserve (CFR) is a measure of coronary microvascular function.

Secondary Outcome Measures :
  1. Change From Baseline in Microvascular Function as Assessed by Intracoronary Administration of Acetylcholine [ Time Frame: Day 180 ]
  2. Change From Baseline in Peripheral Arterial Tonometry [ Time Frame: Day 180 ]
  3. Change in Angina Frequency From Baseline [ Time Frame: 6 months ]
  4. Canadian Cardiovascular Society Angina Class [ Time Frame: 6 months ]

    Canadian Cardiovascular Society angina class grading scale is assessed according to the following scores:

    Grade 1: Ordinary physical activity does not cause angina, such as walking and climbing stairs. Angina with strenuous or rapid or prolonged exertion at work or recreation Grade 2: Slight limitation of ordinary activity. Walking or climbing stairs rapidly, walking uphill, walking or stair climbing after meals, or in cold, or in wind, or under emotional stress, or only during the few hours after awakening. Walking more than two blocks on the level and climbing more than one flight of ordinary stairs at a normal pace and in normal conditions Grade 3: Marked limitation of ordinary physical activity. Walking one or two blocks on the level and climbing one flight of stairs in normal conditions and at normal pace Grade 4: Inability to carry on any physical activity without discomfort, anginal syndrome may be present at rest A higher grade is a worse outcome.

  5. Change From Baseline in Seattle Angina Questionnaire [ Time Frame: 6 months ]
    The SAQ quantifies patients' physical limitations caused by angina, the frequency of and recent changes in their symptoms, their satisfaction with treatment, and the degree to which they perceive their disease to affect their quality of life. Each scale is transformed to a score of 0 to 100, where higher scores indicate better function (eg, less physical limitation, less angina, and better quality of life).

  6. Change From Baseline in SF-36 Scores [ Time Frame: 6 months ]
    The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability.
