Effect of Metformin on Frailty in 12 Subjects
Condition: Aging; Inflammation; Frailty
MeSH terms: Inflammation; Frailty
Intervention: Metformin; Placebo
Intervention description: Oral metformin (up to 2gm) will be given in divided doses; Oral Placebo will be given in divided doses
Intervention MeSH terms: Metformin
Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: Arms Assigned interventions Placebo Comparator: Metformin Chronic metformin administration through augmentation of cellular regeneration and reduction of senescence will improve frailty and physical functioning as studied by the short physical performance battery (SPPB) test. Drug: Metformin versus placebo This will be a pilot, feasibility study. Twelve subjects ≥60 years with stable CAD and prediabetes, who score <9 on SPPB test will be randomized to receive up to 2gm of oral metformin or placebo for 12 months.
Placebo comparator: Placebo Placebo will be compared to chronic metformin administration Drug: Metformin versus placebo This will be a pilot, feasibility study. Twelve subjects ≥60 years with stable CAD and prediabetes, who score <9 on SPPB test will be randomized to receive up to 2gm of oral metformin or placebo for 12 months.
Masking: Double (Participant, Investigator)
Enrollment: 7.0

Minimum age: 60 Years
Healthy volunteers: No

Summary:

      This study will test whether chronic metformin administration will improve longevity of the
      cell, improves its machinery by reducing aging-related biochemical parameters and thereby
      improving physical performance, as measured by short physical performance battery test.
