Summary
Brief summary
This is an open label, multicenter, safety and PK study comparing safety, efficacy, and pharmacokinetic (PK) levels of Tacrolimus Inhalation Powder in lung transplant patients that require reduced tacrolimus blood levels due to kidney toxicity.

Part A of the study will consist of a 12 week safety, efficacy, and PK study.

Part B of the study will be an optional safety extension following successful completion of the 12 week safety, efficacy, and PK study. Patients would have the option to continue Tacrolimus Inhalation Powder for up to 1 year, with a possibility to extend to 2 years depending on the results from Part A.
