Oneness Biotech and Tanner Pharma Group initiate early access program for Fespixon®, a novel macrophage-regulating new therapy for the treatment of diabetic foot ulcers


15th November 2021

Oneness Biotech (4743.TT), a leading biotech company listed on the Taipei stock exchange, and Tanner Pharma UK Limited (“Tanner Pharma”), a specialist pharmaceutical services provider of medicine access solutions, announced the initiation of an early access program for Fespixon in Europe, the UK, Russia, Latin America, the Middle East and North Africa (MENA) where Fespixon is not commercially available.

Fespixon (developed under research code: ON101) is the world's first drug to treat diabetic foot ulcers (DFUs) by regulating the macrophages with superiority in incidence of complete wound closure to the standard care (60.7% vs 35.1%, p=0.0001) according to its publication on the JAMA Network Open. It has been approved by the Taiwan FDA, is under NDA review by China NMPA, and is under multiple NDA submissions to Asian health authorities. A Fast Track designation was granted to Fespixon earlier this year in the US where there is an ongoing Phase 3 study NCT04962139. For US patients who do not qualify for the clinical trial but who may be eligible for expanded access, requests for treatment with Fespixon will be considered on a case-by-case basis via the Oneness expanded access policy.

A diabetic foot ulcer is an open sore or wound on the foot, which can be a life-threatening disease in severe cases and may lead to amputation or even death among diabetic patients. In the past 20 years, there has been limited progress in the drug development process for diabetic foot ulcers, greatly impacting patients around the world. With the unique mechanism to regulate macrophages in chronic wounds caused by hyperglycemia, Fespixon has shown promise as an active-healing option for diabetic foot ulcers. The early access program with Tanner Pharma will enable more DFU patients in the world who would have otherwise gone without treatment to have access to Fespixon.
