3. XF-73 Nasal. XF-73 is the lead product from the XF platform, targeting the prevention of post-surgical infection from Staphylococcus aureus, a leading cause of surgical site infection. The market for XF-73 Nasal is huge. The risk of being infected with MRSA or another Staphylococcal strain is high for a third of the population who carry this bacteria and who have to undergo radical surgery; approximately 14 million people per year in the US alone. Currently pre-surgical treatments, such as Mupirocin, are becoming less effective due to AMR, so the demand for a more effective treatment is high.
As stated in RNS 17/10/2023, in an independent study reporting on the efficacy of XF-73 against 2,527 isolated Staphylococcal cases from around the world, XF-73 was effective against ALL cases tested, including ALL MRSA cases and is effective against ALL tested antibiotic resistance. These independent results endorse the extremely positive XF-73 Phase 2b Clinical Trial results, reported in Q1 2021.
Of course, a drug is not ‘proven’ until it has successfully completed Ph. 3 clinical trials and these have yet to be specified (still waiting for a partnership agreement announcement), let alone completed. “Surgical site infections are serious complications that occur in a significant number of patients post-surgery and can lead to severe life-long morbidities and can even be life-threatening. In addition to the impact on health, surgical sites infections cost approximately 10 Billion USD in the US alone”. The approach of XF-73 is to reduce Staphylococcal surgical site infections through nasal decolonisation. The Ph. 2b clinical trials achieved a 99.5% reduction in Staphylococcus aureus bacterial nasal carriage. The key target for Ph. 3 is the same as that of Ph. 2b, although it will be with a much larger sample of patients and from a different category of surgery. With such a high success rate of this target in 2b trials (99.5%), I very confident of achieving a similar level of success with the large sample in Ph. 3 (although I am no expert in the field!).
In conclusion, the demand for an effective drug to prevent post surgical infection is simply massive, current treatments are increasingly less effective due to AMR and all studies so far indicate that XF-73 is a highly effective treatment.
