About this study

Official title: A Phase 2, Open-Label, Multi-Center, Randomized Trial to Demonstrate the Pharmacokinetics of LCP-Tacro™ Tablets Once Daily and Prograf® Capsules Twice Daily in Adult De Novo Liver Transplant Patients

The purpose of this study is to demonstrate the pharmacokinetics (PK, measuring the amount of medication in blood samples) and safety of a new medicine, LCP-Tacro™ tablets, and Prograf® capsules, a drug commonly taken by transplant recipients to prevent the body from rejecting a transplanted kidney and liver. LCP-Tacro is a tablet containing the same active ingredient (tacrolimus) that is in Prograf capsules, but the tablet has been designed to release tacrolimus over an extended period so that it only has to be taken once daily. LCP-Tacro is an investigational drug.

This study will evaluate the levels of tacrolimus in the blood in the first two weeks after a liver transplant in patients randomly assigned (by chance, like flipping a coin) to take either LCP-Tacro™ tablets (tacrolimus) once daily or Prograf® capsules twice daily. In addition, patients will remain on study drug for 360 days in order to evaluate the relative safety of LCP-Tacro™ tablets compared to Prograf over a longer period of time.

Read the detailed description

This was a randomized, parallel-group, open-label, multicenter study in adult de novo liver transplant patients to demonstrate the pharmacokinetics and safety of once-daily treatment of LCP-Tacro tablets and twice-daily Prograf capsules in the first 2 weeks after live transplantation. The study also compared the efficacy and safety of LCP-Tacro and Prograf over an additional 50 weeks after liver transplantation. Eligible patients were randomized (1:1 ratio) within 72 hours after transplantation (graft reperfusion) to receive either: 1) LCP-Tacr tablets orally once daily (QD) in the morning, with an interval of 24 +/- 1 hours between dosed, starting at 0.07 to 0.11 mg/kg (the starting daily dose for African-American patients was 0.09 to 0.13 mg/kg), or 2) Prograf capsules in 2 equally divided morning and evening doses, starting at 0.10 to 0.15 mg. Subsequent doses of study medications were to be adjusted by the investigator according to local practice to maintain a target whole blood tacrolimus trough level of 5 to 20 ng/mL thought Day 14. Twenty-four-hour pharmacokinetic assessments were performed on Days 1, 7 and 14; additionally whole blood tacrolimus trough levels for statistical analysis were measured on Days 2, 3, 4, 7, 10, 12, 12, 42, 90, 120, 180, 270, and 360. Physicians could also perform tacrolimus trough levels at other times at their discretion. On Day 360, the patients were placed on maintenance immunosuppressive regimen determined by their treating physician. Following completion of the third and final pharmacokinetic assessment on Day 14, patients entered the maintenance phase (Days 15 to 360) of study and remained on their assigned study medication until Day 360. Visits for safety assessments and tacrolimus trough levels during the maintenance phase were on Days 42, 90, 120, 180, 270 and 360.

Immunosuppressive therapy after the conclusion of the study was to be administered at the discretion of the patient's population.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LCP -TacroDrug

    Also called tacrolimus

    LCP-Tacro tablets will be administered orally once daily in the morning starting at 0.07 - 0.11 mg/kg. The starting dose for African-American patients will be 0.09 - 0.13 mg/kg. Subsequent doses of each study drug will be adjusted to maintain target whole blood tacrolimus trough levels of 5 - 20 ng/mL.

  • PrografDrug

    Also called tacrolimus

    Oral Prograf capsules will be administered starting at 0.10 - 0.15 mg/kg per day in two equally divided morning and evening doses. Subsequent doses of each study drug will be adjusted to maintain target whole blood tacrolimus trough levels of 5 - 20 ng/mL.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pharmacokinetics (Cmax and Cmin) of LCP-Tacro™ Compared to Prograf Early After Transplantations (Within the First 14 Days) in Adult de Novo Liver Transplant Recipients.

    The pharmacokinetic parameters (Cmax and Cmin) were evaluated during the first 14 days after liver transplant (on days 1, 7 and 14). The results for Day 14 is listed below as the primary outcome parameter for this study.

    The pharmacokinetic parameter (AUC, 0 to 24 hours post dose) was evaluated during the first 14 days after liver transplant (on days 1, 7 and 14). The results for Day 14 is listed below as the primary outcome parameter for this study.

    Measured: 14 days

  3. Percentage of Patients in Each Treatment Group Achieving Sufficient Tacrolimus Whole Blood Trough Levels (5 to 20 ng/mL) During the First 14 Days Post-transplantation.

    Percentage of patients with trough levels within the therapeutic range of 5 to 20 ng/mL was assessed during the initial 14 days (on days 1, 7 and 14) after liver transplant and compared between the two treatment groups.

    Measured: 1 day

  4. Percentage of Patients in Each Treatment Group Achieving Sufficient Tacrolimus Whole Blood Trough Levels (5 to 20 ng/mL) During the First 14 Days Post-transplantation.

    Percentage of patients with trough levels within the therapeutic range of 5 to 20 ng/mL was assessed during the initial 14 days (on days 1, 7 and 14) after liver transplant and compared between the two treatment groups.

    Measured: 7 days

  5. Percentage of Patients in Each Treatment Group Achieving Sufficient Tacrolimus Whole Blood Trough Levels (5 to 20 ng/mL) During the First 14 Days Post-transplantation.

    Percentage of patients with trough levels within the therapeutic range of 5 to 20 ng/mL was assessed during the initial 14 days (on days 1, 7 and 14) after liver transplant and compared between the two treatment groups.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Jun 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pharmacokinetics (Cmax and Cmin) of LCP-Tacro™ Compared to Prograf Early After Transplantations (Within the First 14 Days) in Adult de Novo Liver Transplant Recipients. (time frame: 14 days). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00772148, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
