Manogepix (APX001A) In Vitro Activity against Candida auris: Head-to-Head Comparison of EUCAST and CLSI MICs
Open accessAbstract
Fosmanogepix is a novel prodrug in a new class of antifungal agents. Manogepix is the active moiety. We evaluated the CLSI and EUCAST MICs of manogepix and eight comparators against Candida auris . CLSI M27-A3 susceptibility testing of manogepix was performed for 122 C. auris isolates and compared to CLSI and EUCAST MICs for manogepix and eight comparators. Differences and agreement were calculated for each compound. Wild-type upper limits (WT-ULs; the upper MIC where the wild-type distribution ends) for manogepix and correlations with other drugs’ MICs were determined.

The finding that MGX was the most active compound tested against all C. auris study isolates is consistent with previous in vitro studies showing MGX to be the most potent antifungal tested against C. auris isolates.
“This is consistent with previous in vitro studies showing MGX to be the most potent antifungal tested against C. auris isolates (21, 22).”

When in vitro activity of MGX was evaluated against eight comparator agents against 122 wild type and non-wild type C. auris isolates, MGX had the most potent antifungal activity against all C. auris strains.
“When in vitro activity of MGX was evaluated against eight comparator agents against 122 wild type and non-wild type C. auris isolates, similar findings were reported, with MGX having the most potent antifungal activity against all C. auris strains (22).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
