Rexgenero, a regenerative medicine company pioneering the development of advanced cell-based therapies to treat chronic limb-threatening ischaemia (CLI), welcomes the news announced today by Atelerix that it has been awarded a grant of £267,000 from Innovate UK.  

The grant will be used to develop gel stabilisation technologies, developed by Atelerix, with the first objective of extending the shelf-life of Rexgenero’s cell-based therapies for storage and transport at room temperature. The project will initially focus on developing a stabilisation technology for REX-001, Rexgenero’s lead development candidate, but is expected to have broad applicability to a wide range of other cell therapies. The project will benefit from additional expertise and experience provided by the Cell and Gene Therapy Catapult.

Atelerix’s patented technology enables the storage and transport of human cells at temperatures between 4°C and 25°C, preserving and extending their functional viability from days to weeks. The technology encapsulates cells in a natural hydrogel for safe shipment and storage. The cells can be recovered when needed by the addition of a gentle, cell-friendly buffer.

REX-001 consists of bone marrow-derived white blood cells extracted from a patient’s own bone marrow (autologous). Rexgenero is currently recruiting 138 patients at 35 sites in countries across Europe for its Phase III SALAMANDER trials of REX-001 for the treatment of CLI in diabetic patients.

CLI is a chronic condition and the most serious form of peripheral arterial disease (PAD) in which a build-up of fatty deposits in the arteries restricts blood supply to leg muscles, leading to chronic ischemic at-rest pain, ulcers, or gangrene in one or both legs. It is a major health and societal issue affecting an estimated 3-5 million people in Europe, growing at 1-2% p.a. due to the link with diabetes and ageing.

Extending the shelf-life of REX-001 will provide increased flexibility for transportation to and from the hospital and facilitate use for physicians treating patients with CLI.                   

Joe Dupere, CEO of Rexgenero commented, "We look forward to initiating this project. Extending the shelf-life of our REX-001 autologous cell therapy is important to ensure that hospitals have the flexibility for less rigid scheduling of operating theatres, making it easier to treat patients and therefore enabling as many patients as possible to be treated with this novel, potentially curative therapy. Room temperature storage and transportation also widens our manufacturing options and should help to drive down cost."

Dr Mick McLean, CEO of Atelerix, added, "We’re excited to be part of this collaboration with Rexgenero and the team at the Cell and Gene Therapy Catapult, and we deeply appreciate the support of Innovate UK to bring us together for this important project. The critical logistics of getting viable cell therapies to the patient are often overlooked and extending the shelf life of therapies such as REX-001 at room temperature would open up an entirely new approach for this sector."

Keith Thompson, CEO of the Cell and Gene Therapy Catapult also added, "We have a long-standing relationship with Rexgenero and have collaborated with them previously to support the commercial manufacture of the REX-001 product. This collaboration underlines the strength of expertise that exists within the UK to support the cost-effective commercialization of cell therapies including in the important area of supply chain technologies. It is a great example of bringing together the capabilities of CGT Catapult and the expert companies that make up the complete UK cell and gene therapy ecosystem."

About Rexgenero
Rexgenero is a clinical-stage regenerative medicine company developing innovative cell-based therapies targeting serious diseases with unmet medical needs.
The Company’s lead candidate REX-001, is a highly innovative autologous cell therapy that is being studied in a Phase III clinical programme in patients with chronic limb-threatening ischaemia (CLI) with diabetes, a poorly treated disease with a high risk of amputation and death. REX-001 has been shown to be effective in Phase I/II and Phase II trials, alleviating CLI in the majority of patients, offering the potential to increase the quality of life of CLI patients by reducing pain, alleviating ulcers, increasing mobility, improving sleep and reducing the need for amputation. Rexgenero is developing REX-001 in a range of indications and, pending approval, intends to launch and market this specialty product in major territories.
Rexgenero is a privately-owned company, which draws on an exceptional understanding of the fundamental science of cell therapies developed by the Andalusian Health Authority (Servicio Andaluz de Salud) and Andalusian Initiative of Advanced Therapies.
The Company was founded in 2015 and is headquartered in London (UK) with R&D and manufacturing operations in Seville (Spain) and Frankfurt (Germany).

About the REX-001 Phase III SALAMANDER Trials
Rexgenero is planning to treat a total of 60 patients with CLI and rest pain and 78 patients with CLI and non-healing ischemic ulcers in two independent Phase III SALAMANDER trials in approximately 30 hospitals across Europe. Clinical trials sites are open and recruiting patients in Spain, Austria, Portugal, Poland, the Czech Republic, Hungary and The Netherlands. The trials are given the name SALAMANDER in reference to the amphibian’s ability to regenerate its tail and limbs.

About Atelerix
Atelerix is a spin out from Newcastle University in the UK that has a transformative technology for the storage and transport of viable cells at room temperature, overcoming the barriers and limitations presented by the current need for cryo-shipping. The Company does this by using its patented process of encapsulating the cells in a natural hydrogel for safe shipment and storage. The cells can be recovered when needed by the addition of a gentle, cell-friendly buffer.

Atelerix’s Impact:

Predictability and reliability in drug discovery models and for cells used as therapies

Extended shelf life for currently short-lived cell therapy products

Customers can use cells and assays immediately on arrival

No need for cryopreservation, nor need for cytotoxic or animal-derived supplements

Cells retain their natural state and are not damaged or altered

The Company was founded in 2017 and is headquartered in Cambridge (UK) with R&D and manufacturing operations in Newcastle upon Tyne (UK).

About Cell and Gene Therapy Catapult
The Cell and Gene Therapy Catapult was established as an independent centre of excellence to advance the growth of the UK cell and gene therapy industry, by bridging the gap between scientific research and full-scale commercialisation.
