INSIDE INFORMATION Combination of ATO with copper salts will allow BioSenic to work towards reducing the dosage of ATO in future trials overall and maintain efficacy Mont-Saint-Guibert, Belgium, March 30, 2023, 7am CET – BIOSENIC (Euronext Brussels and Paris: BIOS), the clinical stage company specializing in severe autoimmune/inflammatory diseases and cellular repair, today announces that data providing additional details about the mechanism of action of its lead API arsenic trioxide (ATO) to prevent autoimmune diseases has now been published in a peer-reviewed paper. The article entitled “Optimal combination of arsenic trioxide and copper ions to prevent autoimmunity in a murine HOCl-induced model of systemic sclerosis” also details an original ATO formula to maximize efficacy in fighting autoimmunity and reducing side effects. The peer-reviewed paper is published in Frontiers in Immunology. This new formulation data has been completed following pre-clinical activities and does not constitute data validated through clinical trial. BioSenic has already demonstrated safety and efficacy of arsenic trioxide in clinical programs targeting Chronic Graft-versus-Host Disease (cGvHD), with a successful Phase 2 trial and a Phase 2a trial on systemic lupus erythematosus (SLE). BioSenic considers that the clinical data it has generated during the last two decades will be adequate for its trial submissions of new indications in the field of autoimmunity and inflammatory diseases. The new peer-reviewed article also demonstrates that the efficacy of ATO is partly related to the generation of Reactive Oxygen Species (ROS), with a marked activation of oxidative cell phenomena and the ensuing selective deletion of activated -pathogenic- immune cells and fibroblasts. They improved the basic API’s efficacy by combining ATO with copper (Cu2+), a divalent cation, which has Fenton-like properties, explaining its capacity to increase oxidative cell stress. BioSenic combines ATO with copper chloride since they both cooperate to trigger the production of ROS. As a result, 50 percent less ATO is needed in combination with copper to observe the same efficacy as ATO alone to treat experimental SSc in a pre-clinical model. BioSenic’s CSO, Dr Carole Nicco, has had a decisive input in the understanding of the mechanism of action of arsenic trioxide, making a significant contribution to this paper and another published in Frontiers in Immunology in 2022 “A Fenton-like cation can improve arsenic trioxide treatment of sclerodermatous chronic Graft-versus-Host Disease in mice”. Biosenic ‘s work in this part of its pipeline is now oriented towards gaining further evidence for using the combination of ATO with copper salts to treat auto-immune diseases and other conditions. She also contributed to the first two papers along these lines, on cGvHD and SSc, as previously described by Kavian et al. (J Immunol 2012 May; Arthritis Rheum 2012 Oct). About BioSenic BioSenic is a biotech company focused on (i) the development of innovative products to address high unmet needs in orthopedics and (ii) exploiting the possibilities offered by the therapeutic use of arsenic salts (mainly arsenic trioxide (ATO) for patients with autoimmune diseases. Key target indications for the platforms include Graft versus Host Disease (GvHD), Systemic lupus erythematosus (SLE), Systemic Sclerosis (SSc) and high-risk tibial fractures and other orthopedics indications, such as osteoarthritis, by combining new and tested, IP protected, techniques. About BioSenic technology BioSenic’s technology is based on two main platforms: 1) The allogeneic cell and gene therapy platform, developed by BioSenic with differentiated bone marrow sourced Mesenchymal Stromal Cells (MSCs) that can be stored at the point of use in hospitals. Its current investigational medicinal product, ALLOB, represents a unique, proprietary approach to organ repair and specifically to bone regeneration, by turning undifferentiated stromal cells from healthy donors into bone-forming cells on the site of injury after a single local injection. These cells are produced via a BioSenic's scalable manufacturing process. Following the CTA approval by regulatory authorities in Europe, BioSenic has initiated patient recruitment for the Phase IIb clinical trial with ALLOB in patients with difficult tibial fractures, using its optimized production process. ALLOB is currently being evaluated in a randomized, double-blind, placebo-controlled Phase IIb study in patients with high-risk tibial fractures, using its optimized production process, after a successful first safety and efficacy study (Phase 1/2a) on fractured long bones, with late delayed union. The patient recruitment has been halted late February 2023 with 57 patients and the new rules permitted for statistical analysis should allow BioSenic to get the main results of this trial much earlier than anticipated in the original protocol, since they are expected by mid-2023. In addition, BioSenic is developing an off-the-shelf next-generation improved viscosupplement, JTA-004, consisting of a unique combination of plasma proteins, hyaluronic acid - a natural component of knee synovial fluid, and a fast-acting analgesic. JTA-004 intends to provide added lubrication and protection to the cartilage of the arthritic joint and to alleviate osteoarthritic pain (OA) and inflammation. In March 2023, after the identification of new OA subtypes, BioSenic delivered a new post-hoc analysis of its Phase III JTA-004 trial on knee OA with positive action on the most severely affected patient population. This new post-hoc analysis changes the therapeutic profile of the molecule and potentially allows for the possibility of stratifying patients for a new, optimized Phase III clinical study. BioSenic, which does not intend to allocate R&D resources to support the clinical development of JTA-004 and will continue to focus its R&D activities on the development of its autoimmune (ATO) and cell therapy (ALLOB) platforms, is now seeking to collaborate with existing and potential partners to explore options for the future development of JTA-004 based on this new post-hoc analysis.
