Pappas, M.D. of the University of Alabama at Birmingham. Top line data from this trial was first announced earlier this year. Additional fosmanogepix clinical and preclinical data will also be presented at separate poster sessions, including a subset analysis of Phase 2 patients with renal insufficiency. In addition, data on Amplyx's preclinical oral Gwt1 inhibitor with highly potent activity against Cryptococcus, APX2039, will be presented at the conference. Details are as follows:

About Fosmanogepix
Fosmanogepix, is a novel, broad-spectrum antifungal agent being evaluated in multiple clinical trials in patients with life-threatening fungal infections.  Fosmanogepix demonstrated a high level of treatment success (80%) in a Phase 2, proof-of-concept study as first-line treatment of infections caused by Candida.  Additional Phase 2 studies of fosmanogepix are ongoing in patients with Aspergillus and rare mold infections, as well as infections caused by multi-drug-resistant Candida auris, a life-threatening fungal infection recently characterized as an "urgent" threat by the Centers of Disease Control (CDC).

Fosmanogepix has a novel mechanism of action, and its active moiety has shown broad-spectrum activity against common species of Candida and Aspergillus, including multi-drug resistant strains, such as C. auris and C. glabrata, as well as rare, hard-to-treat molds including Fusarium, Scedosporium and some fungi from the Mucorales order. Invasive fungal infections result in high mortality rates (30-80%), despite standard-of-care treatment. The frequency of fungi resistant to both the azole and echinocandin classes of drugs is increasing and there is a significant unmet medical need for a new, broad-spectrum antifungal agent.

Fosmanogepix has received Fast Track and Orphan Drug designations from the US FDA for seven separate indications and is also designated as a Qualified Infectious Disease Product (QIDP) for the treatment of four indications.

About MAU868
MAU868, a novel human monoclonal antibody that potently neutralizes the BK virus, which can cause significant morbidity and mortality in transplant patients.  Antibodies to BKV are found in approximately 80 to 90% of adults worldwide, indicating previous infection or exposure to the virus. A weakened immune system may result in BKV reactivation and cause serious disease. In patients who have had kidney transplant, BKV can lead to the loss of the transplanted kidney. BKV reactivation in the bladder can also cause hemorrhagic cystitis. Severe cases require bladder irrigation, clot evacuation, blood transfusion, stenting and nephrostomy. There are currently no approved treatments for renal nephropathy or hemorrhagic cystitis caused by BKV.

MAU868 potently neutralizes all four major genotypes of BKV at sub-nanomolar concentrations and has a high barrier to resistance in vitro.  MAU868 also has neutralizing activity against the closely related JC virus, the cause of progressive multifocal leukoencephalopathy

MAU868 is currently being evaluated in a multicenter, randomized, double-blind, placebo-controlled Phase 2 clinical trial to assess the safety, pharmacokinetics, and efficacy for the treatment of BK viremia in kidney transplant recipients at centers in the US and Canada. The study's primary objectives are to assess the safety of MAU868 in this patient population and to evaluate the efficacy of MAU868 in reducing BKV plasma viral load.
