A new antifungal drug called Novamycin is being developed to treat invasive fungal infections that currently kill up to 80% of patients even with treatment. This matters because invasive fungal diseases—caused by moulds like *Aspergillus fumigatus* and yeasts like *Candida auris*—are becoming more common as cancer chemotherapy, organ transplants, and immunosuppressant drugs weaken patients’ immune defences. Untreated, these infections are 100% fatal. Yet only three main classes of antifungal drugs exist, compared to more than ten classes of antibiotics, and antifungal resistance is a growing but under-recognised threat. Existing treatments also carry serious toxicity risks because they can damage healthy human cells. If successful, Novamycin could change how doctors treat life-threatening fungal infections. The drug is derived from the body’s own natural antifungal defence system, so it selectively kills fungi without harming human cells. Its unique mechanism of action also makes it harder for fungi to develop resistance. This project will turn Novamycin from a laboratory-stage compound into a clinically tested, fully formulated drug candidate—potentially offering a safe, effective, and resistance-limiting therapy for patients who currently have few good options.
View original technical description
Novamycin is a novel antifungal drug being developed by NovaBiotics for front-line treatment of medically unmet, tissue and bloodstream (i.e. invasive) fungal infections caused by difficult to treat moulds and yeasts (including Aspergillus fumigatus and Candida auris). Untreated, invasive fungal disease (IFD) has a mortality rate of 100% and even with treatment, mortality can be as high as in 80% of patients infected with certain fungi. With an ageing global population and medical interventions that suppress our immunity and allow life-threatening fungal infections to establish (chemotherapy for cancer, immunosuppresants, transplant etc.) becoming more commonplace, IFD is occuring more frequently, placing more lives at risk and greater burdens on global health-care systems. There is therefore a clear and urgent need for the development and introduction to clinical practice of new antifungal treatments but a greater awareness of antimicrobial resistance (AMR) against treatments for bacterial infections has overshadowed what is arguably the greater clinical challenge of antifungal AMR. Sufficient progress has undoubtedly yet to be made in providing solutions to bacterial AMR, but research and development in the antifungal sphere is even futher 'behind'. Our solution to this challenge, Novamycin, is active against drug-resistant fungi and has a unique mechanism of action that mitigates opportunites for resistance developing in the future. Novamycin is highly differentiated from existing antifungal treatments (of which there are only 3 main classes versus >10 classes of antibacterial therapy) in how it rapidly kills its target fungi. Novamycin is also not associated with the potentially serious toxicity issues posed by current antifungal treatment options. This is largely because its provenance is the natural antifungal defence system employed by our own bodies and so unlike other antifungal agents that do not always distinguish healthy human cells from a fungal pathogen, Novamycin does not posses any off target pharmacology. The project we propose to undertake will transform Novamycin from a promising, laboratory-stage ‘raw’ antifungal compound to a clinically tested, fully formulated antifungal drug candidate. This would represent a potential breakthrough in advancing Novamycin further towards addressing the significant need for new, safe, effective and resistance limiting therapies for life-threatening invasive fungal infections.
