XF-73 Dermal infection project advances into clinically enabling safety study as part of ongoing agreement with US Government’s NIAID

Brighton, United Kingdom, 15th November 2022 – Destiny Pharma plc (AIM: DEST), a clinical stage innovative biotechnology company focused on the development of novel medicines that can prevent life-threatening infections, is pleased to announce the commencement of an Investigational New Drug (IND) enabling safety study with its novel XF-73 Dermal formulation.

This study is the second of two planned preclinical safety studies of the XF-73 Dermal formulation and will utilise a suite of preclinical services for interventional agent assessment (Contract No. HHSN272201800001I/75N93023F00001) held by the National Institute of Allergy and Infectious Diseases (NIAID), part of the US National Institutes of Health (NIH). The first study met its objectives and generated positive data as announced in February 2022. Following a US Food and Drug Administration (FDA) review of the first study, Destiny Pharma has completed further work developing both the dermal formulation and potential regulatory and clinical plans, which has cleared the path for progression into this second and final preclinical safety study.

Destiny Pharma is developing the novel formulation of XF-73 Dermal for the prevention of infections associated with open wounds and broken skin including diabetic foot ulcers (DFUs) – up to 25% of US diabetic patients may suffer from DFUs in their lifetime and c. 13% have active ulcers. The XF-73 Dermal product is planned to be a fast, cost-effective dermal treatment that kills all relevant bacteria quickly, helping the wound heal and combatting the threat of Antimicrobial Resistance (AMR) through its novel, patented action.

Destiny Pharma will continue to work with NIAID to complete this preclinical safety package which will support future clinical development of XF-73 Dermal in serious wound infections. The study is planned to complete in Q2 2023 and should then be ready to move into clinical trials.

Neil Clark, CEO of Destiny Pharma, said: “We are very pleased with the continuing progress of our novel XF-73 Dermal infection programme which is targeted at meeting a clear clinical need driven by the increasing incidence of diabetes across the world. There are 29 million people diagnosed in the United States alone who are at risk of developing diabetic foot ulcer infections and peak product sales could reach half a billion US dollars. The start of this second preclinical study means that this programme is well placed to deliver a second clinical candidate in 2023 from our XF platform following the excellent Phase 2 clinical results generated for the XF-73 Nasal gel for the prevention of post-surgical infections caused by Staphylococcal aureus.”

About XF-73

XF-73 is the lead drug candidate from Destiny Pharma’s XF platform, initially being developed for the prevention of post-surgical staphylococcal infections, such as methicillin-resistant Staphylococcus aureus (MRSA), which cause significant complications and increased healthcare costs in the hospital setting. XF‑73 has been awarded both Qualified Infectious Disease Product (QIDP) and Fast Track status by the US FDA.

Dermal Infections

XF-73 is being developed as a new treatment for serious dermal infections such as diabetic foot ulcer infections (DFUs) to target a market which is estimated to be a $0.5 billion global sales opportunity based on the incidence of such infections, the costs of the associated medical care and a realistic product pricing of XF-73 in this new market. Driven by the growing number of diabetics and associated complications such as infected DFUs, this represents a significant market opportunity for XF-73. It is estimated that twenty-nine million people in US have a diagnosis of diabetes and of these 13% have active DFUs.

As with all anti-infectives, AMR is also a concern within this market. There is no dominant treatment for DFUs, and specialist physicians are therefore working to find better treatment options, including topical formulations. In addition, the target product profile of XF-73 tested favourably with dermal clinicians looking for better treatments for the smaller market for burns/wound infections and venous leg ulcers.

Destiny’s China partner CMS is also running a programme for XF-73 in superficial skin infections.
