Study population: This study is a single-center prospective observational study that seeks to characterize steady-state tacrolimus pharmacokinetics pharmacodynamics in adult recipients of their first allogeneic HCT. Adult subjects who receive prophylactic tacrolimus for aGVHD prevention, and who receive active follow-up surveillance at our institution, are eligible for enrollment. The study population will consist of subjects treated in the Inpatient Bone Marrow Transplant Unit at the University of North Carolina Medical Center. A total of 50 subjects will be enrolled.

About this study
Official title: Development of a Population Pharmacokinetic Model to Optimize Tacrolimus Dosing in Adult Recipients of Allogeneic Hematopoietic Stem Cell Transplant.
The purpose of this research study is to evaluate tacrolimus plasma concentrations in patients who will undergo an allogeneic hematopoietic stem cell transplant (HCT). The study aims to identify associations between plasma concentrations, baseline demographic characteristics, clinical lab parameters, and genetic factors. These associations will help clinicians determine the best starting dose for tacrolimus in order to minimize risks of aGVHD and tacrolimus-induced toxicities.
Read the detailed description
This study aims to evaluate tacrolimus concentration-time data to characterize tacrolimus inter-individual pharmacokinetic (PK) variability in adult patients who will receive HCT, and to associate concentration-time data, exposure and clearance data with important clinical endpoints such as acute graft-versus-host disease (aGVHD) and tacrolimus-induced toxicities. This study proposes to enroll 50 patients at University of North Carolina Medical Center (UNCMC) who will undergo allogeneic HCT, who will receive tacrolimus starting the third day prior to allogeneic HCT (Day -3) for aGVHD prophylaxis. This will be an observational study, and its goal will be to ideally collect baseline clinical and demographic data, concentration-time data for tacrolimus on Day -3 (3 days before the transplant), Day -2 (2 days before the transplant), Day -1 (one day before the transplant), and Day 0 (the day of the allogeneic HCT) for a full pharmacokinetic profile. A medical chart review will be conducted to extract data on tacrolimus-induced toxicities (i.e., acute kidney injury [AKI], hypertension, metabolic panel changes, etc.) and aGVHD incidence rate up to Day +100 (100 days post-allogeneic HCT). Blood will also be collected for genotyping and will also be collected after the transplant to obtain information for surrogate PD biomarkers of tacrolimus efficacy, such as interleukin 2 (IL2) production and quantifiable nuclear localization of the dephosphorylated nuclear-activated T cells (NFAT). These data will aid in the development of a population-based PK/pharmacodynamic (PD) model that will serve as the foundation for a proposed precision dosing approach to optimize tacrolimus dosing. One of the secondary endpoints will be time to aGVHD, which will be defined as the duration from D0 until the first occurrence of aGVHD, censored at 100 days post-allogeneic HCT (Day +100). In the case of haplo-transplant patients, they will receive tacrolimus starting on Day +5 (as opposed to on Day -3 in non-haplo-transplant recipients). Per standard of care, haplo-transplant patients are initiated on Day +5 (5 days after the transplant). Therefore, in these patients, serial blood draws will be collected on a similar timeline as the non-haplo-transplant patients, but in this case Day +5, Day +6 (6 days after the transplant), Day +7 (7 days after the transplant), and Day +8 (8 days after the transplant; Day +8 is when they reach steady-state). For the PD biomarker studies in haplo-transplant patients, blood draws will occur on Day +9 (9 days after the transplant), Day +16 (16 days after the transplant), and Day +23 (23 days after the transplant) (Figure 2). All other procedures will remain the same.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this research study is to evaluate tacrolimus plasma concentrations in patients who will undergo an allogeneic hematopoietic stem cell transplant (HCT). The study aims to identify associations between plasma concentrations, baseline demographic characteristics, clinical lab parameters, and genetic factors. These associations will help clinicians determine the best starting dose for tacrolimus in order to minimize risks of aGVHD and tacrolimus-induced toxicities.

Questions about this trial
What is this clinical trial studying?
An observational study of Acute GVHD, run by UNC Lineberger Comprehensive Cancer Center 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 4 inclusion and 3 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 17 Oct 2023. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Tacrolimus clearance (time frame: Day +1 of tacrolimus administration to Day +4 of tacrolimus administration). 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 NCT04645667, which also lists 25 linked publications.
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 17 Oct 2023.
