Leveraging Technology to Improve Medication Adherence in Youth With Kidney or Liver Transplant
What this study is about
Can the investigators create an effective way to improve adherence to immunosuppressant medication and reduce rejection, graft loss, and death in adolescents and young adults who have undergone kidney or liver transplantation? The investigators' mobile technology intervention uses real-time electronic pillbox-assessed dose timing and text message prompts to address antirejection medication nonadherence when nonadherence is detected.

The investigators' mobile technology intervention uses real-time electronic pillbox-assessed dose timing and text message prompts to address antirejection medication nonadherence when nonadherence is detected.
Interventions
BEHAVIORAL
mHealth Messaging Intervention Group
Participants will receive an electronic pill box; the research team will instruct participants on how to use this device. Participants will be asked to use the electronic pill box for their prescribed medicines for the duration of the study (up to 16 months). During the 12-week micro-randomized trial, participants will be randomized within person to receive (1) adherence support text messages or (2) no text message after each missed dose, and (1) praise text message or (2) no text message after each on time dose. Dose timing will be determined based on participant report of when they typically take their tacrolimus or sirolimus medicine.
Primary outcome measures
Electronically-measured medication adherence (dose taken or not)
Time frame: 16 months
Participants will use an electronic pillbox to assess daily immunosuppressant adherence (tacrolimus or sirolimus), defined as a binary variable: dose taken or not.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Adolescents and young adults (13-25 years old) who underwent kidney or liver transplantation at least 6 months prior to enrollment
- Currently prescribed tacrolimus or sirolimus.
Exclusion criteria
- Currently receiving dialysis
- Hospitalized for duration of study
- Significant developmental or cognitive delay
- No access to a mobile device that supports text messaging
- Decline to use electronic pill box to monitor daily medication adherence
- Non-English speaking
- If a participant meets inclusion criteria, enrolls in the study, and experiences graft failure potentially leading to dialysis in the case of kidney transplant recipients, the participant will be given the option to continue in the study if they remain on tacrolimus or sirolimus.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
