Description of intervention(s) / exposure
Part A:
This is a double-blinded, placebo-controlled, randomized, dose-ranging study evaluating five different dose levels (0.5, 1.0, 2.5, 5, and 10 mg).

On Day 1 of each period, subjects will receive a single dose of either TFF tacrolimus inhalation powder or a matching placebo. Participants will receive only one dose level of TFF tacrolimus. Participants will be required to fast overnight prior to dosing and for 2 hours following dosing, and will be domiciled at the clinical research center. Treatments will be administered by the clinic staff.

For the 2.5 mg dose level, subjects will be given two administrations, one fasted and one with a high fat meal (50%-60% fat), in a fixed sequence fashion separated by one week. Safety and PK will be monitored on both occasions.

Part B:
This is a double-blinded, placebo-controlled, randomized, multi-dose study evaluating three different dose levels (1.0, 2.5, and 5.0 mg BID). Participants who enrolled in Part A are not eligible to enroll in Part B.

Tacrolimus inhalation powder or matching placebo will be administered twice per day for 6.5 days for a total of 13 doses. Participants will receive only one dose level of TFF tacrolimus.
Participants will be domiciled at the clinical research center and treatments will be administered by the clinic staff.

Summary
Brief summary
TFF Pharmaceuticals Australia Pty Limited is developing the study drug TFF tacrolimus as a potential new treatment to lower the risk of rejection for lung transplantations.

Tacrolimus is an immunosuppressive drug used mainly after an organ transplant to lower the risk of organ rejection. Immunosuppression has been a key factor for the success of organ transplants.

Tacrolimus as inhalation therapy (TFF tacrolimus) is being investigated specifically to lower the risk of rejection for lung transplantations. Tacrolimus is available as oral capsules and as intravenous injections (into the vein). The purpose of this study is to determine safe and tolerable inhaled doses that will be investigated further in future human studies.
