- Analysis of biomarker levels from Lung tissue specimens [ Time Frame: Day 14 ]LOXL2 activity and TGFbeta1 signaling biomarkers such as Snail1 and pSmad3 will be measured in lung tissue from subjects treated with EGCG and compared levels seen in to lung tissue from untreated control subjects.
- Change from baseline in urinary biomarkers of LOXL2 collagen crosslinking [ Time Frame: Change from day 1 to day 14 ]Change from baseline to day 14 in biomarkers representative of LOXL2 collagen crosslinking will be measured in urine samples collected on day 1 and day 14.
- Analysis of serum biomarker Periostin and COMP levels from blood specimens [ Time Frame: Change from day 1 to day 14 ]Change from baseline to day 14 in serum biomarkers associated with IPF
- Maximum plasma concentration of EGCG [ Time Frame: 0, 2, 4, 12 hours post dose ]The maximum plasma concentration [Cmax] following a single dose of EGCG will be determined
- Plasma exposure of EGCG [ Time Frame: 0, 2, 4, 12 hours post dose ]Plasma exposure measured as AUC (area under the concentration curve) following a single dose of EGCG will be determined.
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] of EGCG [ Time Frame: 14 days ]The incidence of treatment-emergent Adverse Events [Safety and Tolerability] following EGCG treatment will be assessed.
