Arm && Interventions

Group	Intervention	Description
Placebo Group	Placebo	Subjects will receive placebo for 2 cycles of 2 consecutive days (first on days 0 \& 1 and then repeated on days 28 \& 29)
Fisetin Group	Fisetin	Subjects will receive the supplement, Fisetin, for 2 cycles of 2 consecutive days (first on days 0 \& 1 and then repeated on days 28 \& 29)

Primary Outcome Measures

Name	Time	Method
Change in immunophenotyping of peripheral T lymphocytes	Baseline, 6 months	Measured by percentage of activated CD4+25+ T cells

Secondary Outcome Measures

Name	Time	Method
Change in 6 minute walk test	Baseline, 6 months	Number of subjects to have a 10% improvement in 6 minute walk test. The 6 minute walk test measures the distance a person is able to walk in 6 minutes.
Change in radiologic imaging in subjects	Baseline, 3 months, 6 months	Number of subjects to have a 10% improvement with the CT scoring system. Radiologist will score the CT scans at each time point and changes in score at each time point will be noted.
Adverse Events	6 months	Number of adverse events reported
Change in quality of life	Baseline, 6 months	Measured using the RAND 36-Short Form Survey Instrument (SF-36). The SF-36 Health Survey is a 36-item, participant-reported survey that measures patient health and disability. Possible scores range from 0 to 100, with 0 indicating maximum disability, and 100 indicating no disability
Use of MRI imaging for assessment of GLILD	6 months	Number of MRI images that were used to assess for GLILD compared to High-resolution Computed Tomography (HRCT) use
Infectious complications	6 months	Number of subjects to experience infectious complications
Change in Forced Vital Capacity (FVC)	Baseline, 6 months	Measured by spirometry to determine the maximal amount of air that can be forcibly exhaled from the lungs after a full inhale, reported as liters (L)
