Study summary

This will be a randomized controlled trial of asymptomatic (Cryptococcal Antigen test)CrAg positive persons in Uganda.

Patients will be randomized to receive preemptive treatment with 1 dose of liposomal amphotericin (10mg/kg) in addition to standard of care fluconazole therapy.

How the enhanced antifungal therapy prevents progression to meningitis in the first 24-weeks and overall survival in those who receive the intervention compared with participants receiving fluconazole per World Health Organisation (WHO) and national standard of care therapy will be evaluated.

Terms in these criteria, in plain language(2)

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.

What researchers measure

Primary outcomes

  1. Number of patients that develop meningitis in the AMBISOME arm compared to the fluconazole arm.

    Comparison will be made between those randomized to single dose liposomal amphotericin + standard of care (fluconazole) vs. standard of care (fluconazole) alone

    Time frame: 24 weeks

Secondary outcomes

  1. Number of grade 3 to 5 clinical adverse events or serious adverse events

    Symptoms causing inability to perform social and functional activities and potentially life threatening symptoms requiring intervention or hospitalization.

    Time frame: within two weeks of enrollment

  2. Number of grade 3 to 5 laboratory adverse events by NIAID DAIDS toxicity scale

    Abnormal laboratory findings that meet the DAIDS categorization of grade 3 and 4.

    Time frame: within two weeks of enrollment

  3. Cost-effectiveness of single dose liposomal amphotericin + fluconazole compared to fluconazole preemptive therapy alone, and compared to no preemptive therapy.

    what will be the added cost required to treat patients with AMBISOME when assessed in light of the outcomes.

    Time frame: 24 weeks

  4. Number of patients that will survive in the 24-week period.

    How many patients will be alive at 24 weeks when the two arms are compared.

    Time frame: 24 weeks
