Study summary

This pivotal, confirmatory trial seeks to independently verify the results observed in the EnACT Phase II Stage 2 trial (MB-70007).

Read the detailed description

Pivotal, prospective, randomized, open-label, non-inferiority trial to compare the efficacy and safety of step-down induction and consolidation therapy for the treatment of cryptococcal meningitis with oral MAT2203 plus flucytosine to standard of care therapy. Randomization will by 1:1:1 to one of two experimental arms or standard of care.

Inclusion criteria

  • CSF cryptococcal antigen (CrAg) positive meningitis
  • Ability and willingness to provide
  • Willing to receive protocol-specified lumbar punctures

Exclusion criteria

Exclusion Criteria:

  • Glasgow Coma Scale \< 15 at time of consent
  • Received >= 3 doses of amphotericin B within prior 30 days
  • Inability to take enteral (oral or nasogastric) medicine
  • Cannot or unlikely to attend regular clinic visits
  • Receiving chemotherapy or
  • Suspected paradoxical immune reconstitution inflammatory syndrome (IRIS)
  • Pregnancy or breastfeeding
  • Previous administration of MAT2203
  • Any condition for which participation would not be in the best interest of the participant or that could limit protocol specified assessments
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.

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.

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.
