Study summary

The purpose of this study is to examine the antifungal activity of recombinant interferon-gamma 1b (rIFN-gamma 1b) given with standard antifungal therapy.

Read the detailed description

Patients are randomized into 1 of 3 parallel groups for a 3-arm, 2-stage, double-blind and dose-ranging study for 14 weeks. In Stage 1, patients are hospitalized for 14 days of acute therapy. Patients receive rIFN-gamma 1b or placebo sc 3 times per week, intravenous (IV) AMB daily, and with or without oral 5-FC every 6 hours. Patients who have the ability to take oral medications, who do not have any significant clinical deterioration during the previous 14 days, and who meet the eligibility criteria can progress to Stage 2. In Stage 2 patients receive 84 days of consolidation therapy (56 days with study drug and 28 days of follow-up). On an outpatient basis, patients receive either placebo or 1 of 2 doses of rIFN-gamma 1b sc 3 times per week, and oral fluconazole daily or oral itraconazole 2 times a day.

Inclusion criteria

Patients may be eligible for Stage 1 if they:

  • Are at least 13 years old.
  • Have consent of a parent, family member, or guardian if less than 18 years of age.
  • Have cryptococcal meningitis for the first time or have had a relapse.
  • Are not on any medications that cannot be taken with fluconazole or itraconazole, if the patient has trouble taking fluconazole.
  • Patients may be eligible for Stage 2 if they:
  • Had no serious decline in health, as determined by their doctor, during the previous 14 days (including mental health).
  • Have received at least 7.5 mg/kg AMB in Stage 1.
  • Have a positive CSF culture for C. neoformans.
  • Can take oral medications.

Exclusion criteria

Exclusion Criteria

Patients will not be eligible for this study if they:

  • Are in a coma.
  • Are pregnant or breast-feeding.
  • Are not using effective methods, if able to have children.
  • Are allergic to imidazole or triazole.
  • Are allergic to rIFN-gamma 1b.
  • Require drugs that are toxic to the kidneys, other than AMB.
  • Received erythropoietin or red blood cell transfusions within 4 weeks of entering the study.
  • Are receiving systemic therapy within 30 days of study or will require it during the study.
  • Have had serious heart disease.
  • Have had multiple sclerosis, peripheral vascular disease, or rheumatologic disorders.
  • Have had disorders of the central nervous system (CNS) (not including emotional problems) or a seizure disorder, or have a current CNS disorder that would interfere with the study.
  • Are receiving therapy for C. neoformans within 90 days of starting the study drug.
  • Have had more than 3 doses of AMB or more than 1200 mg of fluconazole or itraconazole as prior treatment and have begun current treatment for more than 72 hours prior to starting study medication. Fluconazole or itraconazole of no more than 200 mg daily is allowed.
  • Are receiving AMB for C. neoformans within 30 days of starting treatment for the present episode.
  • Are receiving rIFN-gamma 1b treatment within 90 days prior to starting the study drug.
  • Have had therapy which affects the immune system within 30 days prior to starting the study drug.
  • Are receiving investigational therapy for all other signs within 30 days prior to starting the study drug.
  • Are not able to meet the study requirements, in the opinion of the investigator.
  • Require chronic treatment with H2-blockers, and are able to receive only itraconazole in Stage 2.
  • Show signs of or get treatment for another serious opportunistic infection within 4 weeks of starting the study drug.
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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
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 Jun 3, 2009, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
