About this study

Official title: A Phase II, Open-Label, Multi-Center Prospective, Conversion Study in Stable Liver Transplant Patients to Compare the Pharmacokinetics of LCP-Tacro Tablets Once-A-Day to Prograf® Capsules Twice-A-Day

A three sequence, open-label, multi-center, prospective, study in stable liver transplant patients to assess and compare the pharmacokinetics (Cmax, C24, and AUC), and safety of LCP-Tacro (tacrolimus) tablets versus Prograf (tacrolimus) capsules.

Read the detailed description

A three sequence, open-label, multi-center, prospective, study in stable liver transplant patients to assess and compare the pharmacokinetics (Cmax, C24, and AUC), and safety of LCP-Tacro (tacrolimus) tablets versus Prograf (tacrolimus) capsules.

Stable liver 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 14 days with one fixed dose change allowed at Day 15.

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.

What participants receive

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

  • LCP TacroDrug

    Also called tacrolimus

    In the morning of Day 8 (after completing one week treatment with Prograf), all patients will be converted to LCP Tacro QD with a conversion ratio of 0.66-0.8.

    LCP-Tacro will be administered for 14 Days with one fixed dose change allowed at Day 15. LCP-Tacro will be administered orally once daily in the morning, with an interval of 24 ± 1 h between doses.

    Trough levels were to be maintained within predefined therapeutic ranges of 5 to 15 ng/mL.

  • PrografDrug

    Also called Tacrolimus

    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 Day 0 through Day 7 to maintain target trough levels of 5-12 ng/mL.

Study groupRoleWhat they receive
LCP-TacroExperimentalPrograf was administrated BID, doses per product labeling, with an interval of 12±1 hours between the morning and evening doses. Patients continued on the same dose from Day 0 through Day 7. On Day 8, all patients were converted to LCP Tacro QD for 14 Days with one fixed dose change allowed at Day 15. LCP-Tacro was administered orally once daily in the morning, with an interval of 24 ± 1 h between doses. Trough levels were to be maintained within predefined therapeutic ranges of 5 to 15 ng/mL. LCP-Tacro tablets were provided in 3 strengths: 1 mg, 2 mg, and 5 mg oral tablets.

What is being measured

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

  1. Evaluation of Steady State Tacrolimus Trough Levels (C24).

    Patients had a baseline trough level (C24) measured at day 7 before conversion to LCP-Tacro.

    Measured: 7 Days

  2. Evaluation of Steady State Tacrolimus Exposure (AUC 0-24).

    Patients had a baseline AUC measured (0 to 24 hours) at day 7 before conversion to LCP-Tacro.

    The following time points were used to obtain the PK curve for Prograf on day 7: 0 (pre-dose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 12.5, 13, 13.5, 14, 15, 16, 20 and 24 hours after the morning dose.

    Measured: 7 Days

  3. Evaluation of Steady State Tacrolimus Exposure Trough Levels (C24).

    Patients were converted from Prograf to LCP-Tacro on day 7. On day 21, a trough level (C24) was measured.

    Measured: 21 Days

  4. Evaluation of Steady State Tacrolimus Exposure (AUC 0-24) on Day 21.

    Patients were converted from Prograf to LCP-Tacro on day 7. On day 21, AUC was measured (0 to 24 hours).

    The following time points were used to obtain the PK curve for LCP-Tacro on day 21: 0 (pre-dose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 20 and 24 hours post-dose.

    Measured: 21 Days

  5. Safety Evaluation

    A combination of deaths, graft failure and biopsy proven acute rejections (BPAR) was used to evaluate the safety.

    Measured: 52 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LCP Tacro and Prograf in people with Liver Failure, run by Veloxis Pharmaceuticals at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 22 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 28 Aug 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 28 Aug 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?

Evaluation of Steady State Tacrolimus Trough Levels (C24). (time frame: 7 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 NCT00608244, 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2015.
