Subjects will receive Pirfenidone as part of treatment for their restrictive chronic lung allograft dysfunction (RCLAD). Pirfenidone: Subjects will receive pirfenidone for 52 weeks, titrated to 2403 mg/day (3 capsules, 3× daily) after a 4-week titration period (1 capsule, 3x daily for 2 weeks, 2 capsules, 3x daily for 2 weeks) for a total of 56 weeks of pirfenidone. Eligible participants will continue pirfenidone beyond 56 weeks.

PRIMARY outcome

Timeframe: From initiation of pirfenidone until discontinuation or until 56 weeks, which ever comes first.

The outcome will be the ratio of tacrolimus-while-taking-pirfenidone to tacrolimus-before-pirfenidone corrected for the subject's specific steady-state tacrolimus concentration.

SECONDARY outcome

Timeframe: FVC change from baseline (screening) to 1 year or death, whichever comes first.

The investigators will evaluate change in FVC from baseline to 1 year after pirfenidone start based on pulmonary function tests done as part of routine clinical care (usually obtained every 3 months) or death, whichever comes first.

SECONDARY outcome

Timeframe: Change between chest CT at screening and in 1-year follow up CT scan performed as part of routine clinical care or death, whichever comes first.

The investigators will evaluate the annual change in percent of lung affected by reticulation comparing the chest CT scan at screening and a 1-year follow up CT scan performed as part of routine clinical care or death, whichever comes first.

Interval -0.8 to 6.8

SECONDARY outcome

Timeframe: Change between Chest CT at screening and 1-year follow up CT scan performed as part of routine clinical care or death, whichever comes first.

The investigators will evaluate the change in traction bronchiectasis score on chest CT scan at screening and in a 1-year follow up CT scan performed as part of routine clinical care or death, whichever comes first. The extent of traction bronchiectasis was first scored in each of the six lung lobes separately (right upper, middle, and lower lobes, and left upper, lingula, and lower lobes) as 0-absent, 1-mild, 2-moderate, or 3-severe, and then summed into a total traction bronchiectasis score \[range 0-18 points\], with higher values reflecting greater extent of traction bronchiectasis.
