New drug shows promise against superbug fungus in small trial
NCT ID NCT04148287
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This Phase 2 trial tested an experimental antifungal drug called APX001 (fosmanogepix) in 9 adults with blood or deep-organ infections caused by Candida auris, a fungus that often resists standard treatments. The drug was given by IV or mouth for up to 42 days. The goal was to see if the infection cleared and patients survived without needing other antifungals. Because the study was very small and had no placebo group, the results are encouraging but not conclusive.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- APX001 (fosmanogepix), an antifungal drug given by IV or mouth
- What this could lead to
- If it works, this could offer a new treatment option for people with dangerous Candida auris infections that resist standard antifungals.
- What could go wrong
- This was a very small study (9 people) with no comparison group, so results are preliminary. The drug may not work as well in larger, more diverse groups, and side effects are still being studied.

Inclusion Criteria: * Limited or no treatment options due to resistance, contraindication, intolerance or lack of clinical response to standard of care antifungal therapy, as advocated by the relevant regional/country treatment guidelines * Established mycological and clinical diagnosis of candidemia and/or invasive candidiasis caused by Candida auris * Able to have pre-existing intravascular catheters removed and replaced (if necessary) * Females of childbearing potential with male partners, and males with female partner(s) of childbearing potential, must agree to use 2 forms of highly effective contraception throughout the duration of the study and for 90 days following the last study drug administration. Females of childbearing potential must have a negative urine pregnancy test within 96 hours prior study entry. * Wiling to participate in the study, willing to give written informed consent, and willing to comply with the study restrictions; where permitted by local regulations, written informed consent from a legal authorized representative (LAR) will be obtained for patients who are unable to give consent Exclusion Criteria: * Life expectancy of less than 7 days in the opinion of the Investigator * Human immunodeficiency virus-infected patients who are receiving antiretroviral therapy that are moderate to strong inducers of CYP3A4, or who have detectable viremia, or who have had an active opportunistic infection within 6 months prior * Alanine aminotransferase or aspartate aminotransferase greater than or equal to 5 times the upper limit of normal * Total bilirubin greater than 3 time the upper limit of normal, unless isolated hyperbilirubinemia or due to documented Gilbert's disease * Pregnant or lactating female patient * Inappropriate fungal infection source control * Investigational drug administered within 30 days prior to dosing or five half-lives whichever is longer * Diagnosis of deep-seated Candida-related infections causing hardware associated septic arthritis, osteomyelitis, endocarditis, myocarditis, hepatosplenic candidiasis, or a central nervous system infection or site of infection that would require antifungal therapy to exceed the maximal duration of study drug treatment
