Pharmacokinetics of LCP-Tacro in Stable Kidney Transplant Patients

Intervention / Treatment
Detailed Description
A three sequence, open-label, multi-center, prospective, study in stable kidney transplant patients to assess and compare the pharmacokinetics (Cmax, C24, and AUC), and safety of LCP-Tacro (tacrolimus) tablets versus Prograf (tacrolimus) capsules.
Stable kidney transplant patients who fulfill all I/E criteria will be enrolled and kept on Prograf for 7 days. Following a 24-hour PK study on Day 7 to determine pharmacokinetics for Prograf, all patients will be converted to once daily LCP-Tacro for 7 days with no dose changes allowed. On Day 14 and Day 21 a 24-hour LCP-Tacro PK study will be performed. On Day 22 patients will be converted back to their original twice daily dose of Prograf for a safety follow-up period of 30 days ending with a safety assessment on day 53.

- Patient treated for acute cellular rejection within the 30 days prior to enrollment
- Patient who is HCV negative and has received an HCV positive (HCV RNA by PCR or HCV antibody) donor kidney
- Patient has a current malignancy or a history of malignancy (within the past 5 years), except basal or non-metastatic squamous cell carcinoma of the skin that has been treated successfully
- Patient has uncontrolled concomitant infection, a systemic infection requiring treatment, or any other unstable medical condition that could interfere with the study objectives
- Patient has severe diarrhea, vomiting, active peptic ulcer or gastrointestinal disorder that may affect the absorption of tacrolimus

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: LCP-Tacro (tacrolimus)
Experimental: LCP Tacro; investigational product LCP-Tacro tablets were provided in 3 strengths: 1 mg, 2 mg, and 5 mg oral tablets.
|
Prograf will be administrated twice a day, per product labeling, with an interval of 12 ± 1 hours between the morning and evening doses. Patients will continue on the same dose on Day0 through Day 7 to maintain target trough levels of 7-12 ng/mL. On the morning of Day 8, following the final blood draw for the PK assessment, patient will be converted to LCP-Tacro using the conversion Ratio 0.66-0.8. LCP-Tacro tablets will be administered orally once daily in the morning, with an interval of 24 ± 1 hours between doses. Other Names: Tacrolimus modified-release LCP-Tacro tablets were provided in 3 strengths: 1 mg, 2 mg, and 5 mg oral tablets.
