Brief Summary:
This is a randomized, placebo-controlled, double-blind, parallel arm, multi-center Phase 2b study.

Condition or disease Intervention/treatment Phase
Aging Frailty Biological: Longeveron Mesenchymal Stem Cells (LMSCs) Other: Placebo Phase 2

Detailed Description:
The objectives of this study are to assess safety and efficacy of three doses of Longeveron Mesenchymal Stem Cells (LMSCs) compared to placebo on 1) functional mobility and exercise tolerance, 2) patient-reported physical function, and 3) the inflammatory cytokine biomarker tumor necrosis factor (TNF-a).

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 120 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase 2b, Randomized, Blinded and Placebo-Controlled Trial to Evaluate the Safety and Efficacy of Longeveron Allogenic Human Mesenchymal Stem Cells Infusion in Patients With Aging Frailty
Actual Study Start Date : July 6, 2017
Estimated Primary Completion Date : June 2, 2019
Estimated Study Completion Date : September 28, 2019

Arm Intervention/treatment
Experimental: Study Group A
Single peripheral IV infusion of 25 million Longeveron Mesenchymal Stem Cells (LMSCs)
Biological: Longeveron Mesenchymal Stem Cells (LMSCs)
Intravenously delivered
Experimental: Study Group B
Single peripheral IV infusion of 50 million Longeveron Mesenchymal Stem Cells (LMSCs)
Biological: Longeveron Mesenchymal Stem Cells (LMSCs)
Intravenously delivered
Experimental: Study Group C
Single peripheral IV infusion of 100 million Longeveron Mesenchymal Stem Cells (LMSCs)
Biological: Longeveron Mesenchymal Stem Cells (LMSCs)
Intravenously delivered
Experimental: Study Group D
Single peripheral IV infusion of placebo
Other: Placebo
Intravenously delivered

Primary Outcome Measures :
  1. Change from baseline in 6 Minute Walk Test (6MWT) compared to placebo [ Time Frame: Baseline and 180 days post-infusion ]
    Change from baseline in 6MWT compared to placebo at 180 days post-infusion

Secondary Outcome Measures :
  1. Change in patient reported outcome of overall physical function capacity using the PROMIS-Physical Function-Short Form 20a compared to placebo [ Time Frame: 180 days post-infusion ]
    Change from baseline in physical function will be measured to assess Patient-Reported Outcome Measurement compared to placebo at 180 days post infusion.

  2. Change in TNF-a compared to placebo [ Time Frame: 180 days post-infusion ]
    Change in serum TNF-a compared to placebo

  3. Have a Canadian Study on Health and Aging (CSHA) Clinical Frailty Scale score of 5 "mildly frail" or 6 "moderately frail".
  4. Have a 6 minute walk distance of > 200m and < 400 m. Distances of two 6MWTs are to be within 15% of each other.
  5. Have a serum TNF-α level > 2.5 pg/mL

Exclusion Criteria:

  1. Be unwilling or unable to perform any of the assessments required by the protocol.
  2. Have a diagnosis of any disabling neurologic disorder, including, but not limited to, Parkinson's disease, Amyotrophic Lateral Sclerosis, multiple sclerosis, cerebrovascular accident with residual deficits (e.g., muscle weakness or gait disorder), or diagnosis of dementia.
  3. Have a score ≤ 24 on the Mini Mental State Examination (MMSE)
  4. Have poorly controlled blood glucose levels (HbA1c >8.0%).
  5. Have a clinical history of malignancy within 2.5 years (i.e., subjects with prior malignancy must be cancer free for 2.5 years) except curatively-treated basal cell carcinoma, melanoma in situ or cervical carcinoma.

  8. Be using chronic immunosuppressant therapy such as high-dose corticosteroids or TNF-α antagonists (prednisone use at doses of < 5 mg daily is allowed).
  9. Test positive for hepatitis B virus

    a. If the subject tests positive for anti-hepatitis B core antigen (HBc) or anti-HBs, they must be currently receiving treatment for Hepatitis B prior to infusion and remain on treatment throughout the study.

  10. Test positive for verimic Hepatitis C virus, HIV1/2, or syphilis
  11. Have a resting blood oxygen saturation of <93% (measured by pulse oximetry).
  12. Known or suspected alcohol or drug abuse within three years preceding Screening
  13. Have a known hypersensitivity to dimethyl sulfoxide (DMSO).
  14. Be an organ transplant recipient (other than transplantation for corneal, bone, skin, ligament, or tendon).
  15. Be actively listed (or expected future listing) for transplant of any organ (other than corneal transplant).
  16. Have any clinically important abnormal screening laboratory values, including, but not limited to:
