NCT03451006

Brief 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.

Outcome Measures

Primary Outcomes (6)

  • Change in Frailty

    Frailty will be measured by the Short Physical Performance Battery (SPPB). The short physical performance battery (SPPB) is a group of measures that combines the results of the gait speed, chair stand and balance tests. It has been used as a predictive tool for possible disability and can aid in the monitoring of function in older people. The scores range from 0 (worst performance) to 12 (best performance). Frailty is defined as a score of \<9.

    Baseline, 12 months

  • Change in Balance Score Standing With Feet Close Together

    This measure is part of the SPPB. The scores range from 0 (not attempted), to 2 (held for 10 seconds). Ability to stand longer in this position indicates greater balance.

    Baseline, 12 months

  • Change in Balance Score Standing in Semi Tandem Position

    This measure is part of the SPPB. The semi tandem position is the heel of one foot place by the big toe of the other foot. The scores range from 0 (not attempted), to 2 (held for 10 seconds). Ability to stand longer in this position indicates greater balance.

    Baseline, 12 months

  • Change in Balance Score Standing in Full Tandem Position

    This measure is part of the SPPB. The full tandem position is with the feet directly in front of each other. The scores range from 0 (not attempted), to 2 (held for 10 seconds). Ability to stand longer in this position indicates greater balance.

    Baseline, 12 months

  • Change in Gait Speed

    This measure is part of the SPPB. Subjects will be asked to walk 8 feet or 2.44 meters at their usual pace. They will be allowed to use a cane or other walking aid if it is their custom. Scores range from 0 = could not do to 4 =\<3.1 seconds.

    Baseline, 12 months

  • Change in Score, Standing Test From Chair

    This measure is part of the SPPB. Subjects will be asked to try to stand up from a chair 5 times with arms folded across their chest, and will be timed. Scores range from 0 to 4, with 0 = unable to stand without using arms, and 4 = completing 5 stands in \<11.1 seconds.

    Baseline,12 months

Secondary Outcomes (5)

  • Change in Interleukin 6 (pg/ml)

    Baseline, 12 months

  • Change in Matrix Metalloproteinase (ng/ml)

    Baseline, 12 months

  • Change in Plasminogen Activator Inhibitor

    Baseline, 12 months

  • Change in Monocyte Chemotactic Protein-1

    Baseline, 12 months

  • Change in Activin

    Baseline, 12 months
