Acombat BioSenic

BioSenic is a leading biotechnology company that specializes in the development of clinical assets issued from: (Yo), the ALLOB allogeneic cell therapy platform and (ii) the Arsenic trioxide (ATO) platform. Key target indications for the platforms include graft-versus-host disease (GVHD), systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and high-risk tibial fractures.

Following the merger in October 2022, BioSenic combines the strategic positioning and strengths of Medsenic and Bone Therapy. The merger also allows Biosenic to add to its innovative cell therapy platform and strong intellectual property for tissue repair protection an entirely new arsenal of various anti-inflammatory and anti-autoimmune formulations utilizing the immunomodulatory properties of ATO/OATO.

BioSenic is based in Louvain-la-new Science Park in Mont-Saint-Guibert, Belgium. More information is available at

On BioSenic technology platforms

BioSenic The technology is based on:

1) The allogeneic cell and gene therapy platform, developed by Bone Therapeutics with differentiated mesenchymal stromal cells (MSCs) of bone marrow origin that can be stored at the point of use in hospitals. Its current investigational drug, ALLOB, represents a unique, patented approach to organ repair and specifically bone regeneration, by converting undifferentiated stromal cells from healthy donors into bone-forming cells at the site of injury. These cells are produced through a proprietary BioSenic scalable manufacturing process. Following approval of the CTA by regulatory authorities in Europe, the company has begun patient recruitment for the phase IIb clinical trial of ALLOB in patients with difficult tibial fractures, using its optimized production process. ALLOB continues to be evaluated for other orthopedic indications, including spinal fusion, osteotomy, maxillofacial, and dental, and should be of value in new indications when cells will be further adapted or transformed with additional targeting properties.

two) arsenic trioxide (ATO) platform developed by Medsenic. The immunomodulatory properties of ATO have demonstrated a dual basic effect on cells of the immune system. The first effect is increased cellular oxidative stress on activated B, T or other cells of the innate/adaptive immune system to the point that they will enter a cell death (apoptosis) program and be eliminated. The second effect is the potent immunomodulatory properties of various proinflammatory cytokines involved in inflammatory or autoimmune cellular pathways. A direct application is its use in oncoimmunology to treat GVHD (graft versus host disease) in its established chronic stage. GvHD is one of the most common and clinically significant complications affecting long-term survival of allogeneic hematopoietic stem cell transplantation.hello-SCT). GvHD is primarily mediated by the transplanted immune system which can cause severe multi-organ damage. Medsenic had been successful in a phase II trial with its intravenous formulation, allowing the FDA and EMA to grant arsenic trioxide orphan drug designation status and is heading towards an international Phase III confirmation study, with a new IP-protected oral formulation (OATO).

Moderate to severe forms of systemic lupus erythematosus (SLE)° are another selected target, using the same oral formulation. ATO has shown good safety and significant clinical efficacy in various target organs (skin, mucous membranes and the gastrointestinal tract) in a phase IIa to study.
Systemic Sclerosis is also part of the clinical pipeline of BioSenic. Preclinical studies in relevant animal models are positive. This gives a good basis to launch a Phase II clinical protocol for this serious disease that severely affects the skin, lungs or vascularization, and no real current effective treatment.
