HXP124: an onychomycosis therapeutic opportunity
Global onychomycosis market
US$3.06 billion in 2015 and projected to reach US$4.7 billion by 2021. Major deficiencies in current therapies.
• Poor efficacy rates• Long treatment times• Oral therapies can be toxic• Expensive
—Estimated that between 50 and 90% of individuals with fungal nail infections are not receiving treatment.
Large potential for rapid growth in the market with an effective product.

HXP124
Hexima is developing a novel therapeutic (HXP124) for the treatment of fungal nail infections (onychomycosis).
HXP124 has the potential to be superior to current therapies.• Potent, broad-spectrum antifungal molecule
—Member of the Plant Defensin class of molecules
• Readily penetrates nails (>20% within 72 h)• Rapidly kills the fungus
12
Plant defensins
Potent, broad spectrum antifungal agents.• Small peptides• Naturally produced by plants for protection
against fungal diseases• Water soluble• Very stable in formulation• Manufacturable using yeast fermentation• Rapidly purified to achieve quality required
for clinical trials
Hexima has built the world’s leading competency in plant defensins and a broad IP portfolio.• 6 patent families relating to the use of plant defensins to treat human and plant fungal disease.• Patent coverage for plant defensins as a treatment for onychomycosis valid to 2033 (if granted).
13
HXP124: a broad-spectrum antifungal defensin
Kills several human fungal pathogens including the yeast Candida and the agents responsible for fungal nail infections.
Very specific for fungal cells. • Not active against mammalian cells• Not active against bacteria
14
No treatment Low dose (10 µg/mL)
High dose(50 µg/mL)
Growth of Trichophyton rubrum (causative agent of ~90% of fungal nail infections) in the presence and absence of HXP124.
HXP124 kills fungi more readily than current treatments for nail infections
15
Kills fungal cells within 30 min.• Inefficient killing by drugs currently
on the market means the fungus is likely to become resistant during long treatment times and will regrow when treatment is stopped.
Fluorescence Associated Cell Sorting (FACS) of Propidium Iodide stained cells was used to identify living and dead Candida albicans cells after 30 min treatment with antifungal molecules.

Fungi do not readily develop resistance to HXP124We cultured C. albicans in the presence of
HXP124 and efinaconazole to examine how quickly resistance could develop.
C. albicans does not become resistant to HXP124 after 15 rounds of selection.• HXP124 has very high kappa (steepness of
killing curve) and rapid cell killing kinetics, both of which are important to prevent the development of resistance.
• C. albicans becomes highly resistant to efinaconazole (Jublia® active ingredient) after <10 rounds of selection.

Dose site
HXP124 accumulates in the nail under the site of application and diffuses sideways to areas that were not dosed.
Nails dosed with HXP124 in nail penetration assays were drilled to collect nail material from the dose site (yellow arrow) and the edge of the nail (white arrow) and the amount of HXP124 present at each site was analysed.
HXP124 is as effective as Jublia®
in an infected nail model
MedPharm (UK) have tested HXP124 in an “infected nail model” to provide additional confidence that HXP124 passes through nails and kills fungal cells.• Industry standard assay.• Nail and fungal growth conditions more
representative of clinical condition.
Jublia® and Penlac® were used as comparator products in this study.• Jublia® is the current industry ‘gold
standard’.
