Study summary

The overall aim of the study is to prospectively investigate the impact of two maintenance calcineurin inhibitor immunosuppressive regimens: once-daily extended release tacrolimus and twice-daily tacrolimus on subpopulations of T and B cells and alloreactive T cells as well as on renal allograft function.

Read the detailed description

Kidney transplantation is the treatment of choice for most patients with end-stage renal disease. Lifelong immunosuppressive therapies are required to prevent organ rejection. However, long term exposure to immunosuppressive therapy after kidney transplantation can place patients at risk for multiple adverse events. The optimal immunosuppressive therapy is not well established. Tacrolimus, a calcineurin inhibitor (CNI) is highly effective in preventing acute rejection after organ transplantation (2). It is used as part of the immunosuppression regimen for the majority of kidney and liver transplant recipients (3). However, treatment with current formulation of Tacrolimus generates high peaks and low troughs in drug concentrations in the blood. It is known that high exposure to CNI is associated with renal toxicities and adverse events (4). New once-daily dosage formulations are now developed with the hope of minimizing side effects while maintaining excellent outcomes (5-8).

LCP-Tacro (Envarsus® XR, Veloxis Pharmaceuticals), a new once-daily formulation of tacrolimus, was approved by the FDA in 2015 for conversion from twice-daily tacrolimus in kidney transplant recipients. It is a prolonged-release tacrolimus formulation, utilizing a MeltDose drug delivery technology designed to improve the bioavailability of drugs with low water solubility (1). Recent clinical data demonstrated that once-daily LCP-Tacro has improved pharmacokinetic bioavailability, rapid achievement of therapeutic trough levels, less fluctuation and swing in whole blood concentration, non-inferior efficacy and similar safety, with lower tacrolimus dose than other tacrolimus formulations.

The target population is adult recipients of immediately functioning living and deceased donor renal allografts. Immediate function will be defined as the absence of the need for hemodialysis in the first week following renal transplantation.

Terms in these criteria, in plain language(12)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2017 to primary completion in Feb 2021, 41 months.

Results were first posted in Apr 2023, 2 years 1 month after primary completion.

Of 66 phase 3 interventional studies under Kidney Failure, Chronic, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 48. This study's 41 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 10, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
