Description
Inclusion Criteria:
To be eligible to participate in this study, all candidates must meet the following eligibility criteria at Baseline or at the time point specified in the individual eligibility criterion listed:
All Participants
1. Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information in accordance with national and local subject privacy regulations
Subjects with Sarcopenia
- Men and postmenopausal women of 65 years of age or older
- Gait speed measured over 4 meters of <1.0 m/s OR grip strength < 26 kg for men or < 16 kg for women.
- Appendicular skeletal muscle adjusted for BMI by DXA ≤ 0.789 for men and ≤ 0.512 for women.
- Weigh at least 40kg;
- Self-reported difficulty climbing 10 steps OR walking outside on level ground for 1/4 mile
Healthy Controls
- Men and postmenopausal women of 65 Years of age or older
- Body mass index (BMI) between 18.5 and 30 kg/m2 inclusive at the time of Screening
- Measures of Physical Performance and Lean Mass exceed thresholds defined for Sarcopenia group.
- ≥ 150 minutes/week moderate-intensity physical activity OR regular engagement in resistance training ≥ 2 days/week
- Willing to maintain a consistent diet and pattern of physical activity for the duration of the study
Exclusion Criteria:
Candidates will be excluded from study entry if any of the following exclusion criteria exist at Screening:
- History of human immunodeficiency virus (HIV), hepatitis B or C, or tuberculosis (TB)
- Immunocompromized subjects, as determined by the Investigator, based on medical history, physical examination, or laboratory testing, or due to prior or current immunosuppressive or immunomodulating treatment, including, but not limited to, HIV infection, history of organ transplantation, and anti-rejection therapy
- Acute infection (urinary, respiratory, other) within past week or hospitalization within one month
- Participation in any interventional clinical study within 12 weeks
- A lower limb fracture in the past 6 months or any impairment or disease severely affecting gait (e.g. stroke with hemiparesis, myasthenia gravis, Parkinson's disease, peripheral polyneuropathy, intermittent claudication in advanced peripheral vascular disease, spinal stenosis, or severe osteoarthritis of the knee or hip);
- Any underlying muscle disease including active myopathy or muscular dystrophy.
- Confirmed diagnosis of heart failure classified as New York Heart Association Class III and IV (e.g. cardiomyopathy) or hypertrophic cardiomyopathy.
- Type I diabetes or uncontrolled Type 2 diabetes (HA1C ≥ 9).
- Requires regular assistance from another person for general activities of daily living (e.g. bathing, dressing)
- Moderate to Vigorous Exercise performed in week prior to study visits (temporary exclusion - will be rescheduled)
- Any other condition judged by the Principal Investigator or Study Physician to preclude safe participation in the study
