Conditions
Brief summary
Researchers are trying to learn more about using sublingual (absorption under the tongue) tacrolimus in blood and marrow transplant patients.
Detailed description
Initial doses will be given via sublingual route and a steady state trough level will be collected after 4 consecutive doses. Participants will then switched to oral tacrolimus, the dose adjusted for a goal trough 8-12ng/mL, and another steady state trough will be drawn.
Interventions
Recommended starting dose will be in accordance with the established protocol (0.04 mg/kg/dose of ideal body weight), initially administered sublingually for four consecutive doses.

Eligibility
Inclusion criteria
* Individuals will be identified from within the adult allogeneic BMT program at Mayo Clinic in Rochester, Minnesota * Adults prescribed tacrolimus for treatment or prevention of Graft Versus Host Disease (GVHD)
Exclusion criteria
* Vulnerable populations * Patients with contraindications to tacrolimus, inclusive of hypersensitivity, history of posterior reversible encephalopathy syndrome or calcineurin-inhibitor induced thrombotic microangiopathy * Lacking the capacity to consent in English and declining to participate in research
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Median Tacrolimus Sublingual Trough Level | 14 days | Trough level is the lowest concentration in the patient's bloodstream and was collected after four consecutive sublingual doses. Measured as ng/mL. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Median Sublingual (SL) to Oral (PO) Ratio | 14 days | Total daily dose will be divided by the corresponding trough whole blood concentration for each route of administration to determine the dosing ratio of SL:PO. \[(daily doseSL/blood concentrationSL)/(daily dosePO/blood concentrationPO)\] for each individual participant. |

Outcome results
Median Tacrolimus Sublingual Trough Level
Trough level is the lowest concentration in the patient's bloodstream and was collected after four consecutive sublingual doses. Measured as ng/mL.
Time frame: 14 days

|---|---|---|
| Allogeneic Blood or Marrow Transplantation | Median Tacrolimus Sublingual Trough Level | 11.3 ng/mL |
Median Sublingual (SL) to Oral (PO) Ratio
Total daily dose will be divided by the corresponding trough whole blood concentration for each route of administration to determine the dosing ratio of SL:PO. \[(daily doseSL/blood concentrationSL)/(daily dosePO/blood concentrationPO)\] for each individual participant.
Time frame: 14 days
| Arm | Measure | Value (MEDIAN) |
