Our Focus

FivepHusion is optimising cancer therapy to improve patient treatment outcomes & quality of life.

We are developing Deflexifol™, a novel anti-cancer drug designed to address the safety and efficacy limitations of standard of care therapy.

Deflexifol™ combines the drug 5-fluorouracil (5-FU) and its biomodulator leucovorin, used to improve the anti-tumour activity of 5-FU.

These drugs are commonly used to treat various solid tumours including colorectal, pancreatic, and breast cancers. The Deflexifol™ all-in-one formulation delivers both agents simultaneously at a physiological pH, thereby improving their tolerability, safety, and anti-tumour activity.

Deflexifol™

Deflexifol™ has been administered to over 60 end-stage solid tumour patients across three phase I/II clinical trials to date, and is poised to enter phase III in 2025.

Deflexifol™ is associated with significantly improved tolerability compared to standard formulations, and has demonstrated a positive safety and efficacy profile.

Deflexifol™ is positioned to replace and enhance standard of care 5-fluorouracil therapy to improve patient treatment outcomes and quality of life.

As an optimised replacement of standard 5-fluorouracil chemotherapy, Deflexifol™ has the potential to improve the treatment outcomes and quality of life for patients with indications such as colorectal, pancreatic, gastric and breast cancers, which total over six million new cases globally each year.

The unique attributes of Deflexifol™ also enable potential use in patients and indications where standard 5-FU is not currently used. The use of Deflexifol™ for treating childhood brain cancers will be investigated in a phase clinical I/II trial commencing this year.

Standard 5-FU has previously demonstrated promising activity in a rare paediatric brain cancer called ependymoma, but the treatment was limited by toxicity. It is expected that the improved tolerability and efficacy of Deflexifol™ will benefit these young patients.

Deflexifol™ is being developed to address cancers with high unmet medical needs, including advanced solid tumours and paediatric brain cancers.
