Study summary

The aims of this study are to obtain pharmacokinetic data on interactions between dolutegravir (DTG) and immunosuppressant drugs (Cyclosporine A, Tacrolimus, Sirolimus and Mycophenolic acid) in solid organ transplant (SOT) recipients to provide proof of principle data that DTG plus 2 nucleosides (NUCs) is safe and effective in HIV-infected SOT recipients.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. patients >18 years old who provide signed and dated ;
  2. Males and females;
  3. SOT recipients (heart, liver or kidney);
  4. On stable antiretroviral therapy (ART) for ≥6 months preceding the screening visit;

  6. Absence of major reverse transcriptase or integrase gene mutations affecting study drug efficacy by proviral DNA sequencing

Exclusion criteria

Exclusion Criteria:

  2. HIV patients who require treatment with DTG medications;
  3. History or presence of an allergy or intolerance to the study drug;
  4. Active opportunistic infection;

Terms in these criteria, in plain language(3)

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.

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.

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.

Results

Posted Sep 30, 2025
Limitations and caveats
The study was a single-arm pilot trial with a small sample size, which may limit generalizability. The number of participants included in the pharmacokinetic analysis of cyclosporine A was limited, and therefore insufficient to support robust statistical conclusions. No control group was included, and all participants received DTG-based ART. Further studies are needed to confirm findings in larger cohorts.

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 Sep 30, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
