Orgenesis Inc, a pioneering, global biotech company committed to lowering costs, accelerating commercialization, and transforming the delivery of cell and gene therapies (CGTs), today announced that it has developed a breakthrough and patented manufacturing process for Bioxomes™, through its collaboration and licensing agreement with ExcellaBio Ltd.
Exosomes, or extracellular vesicles (EVs), are small vesicles that transfer DNA, RNA, and proteins to other cells, thereby altering the function of the targeted cells. Exosomes are believed to provide the same therapeutic benefit of cells without the risks and difficulties of administering entire cells to patients.
Together, Orgenesis and ExcellaBio have developed Bioxomes, which are synthetic exosomes/EVs. Until now, exosome/EV production has been based on conventional ultracentrifugation or ultrafiltration. These are both complex and costly techniques. Bioxomes are engineered and produced through a patented method as membrane nanoparticles isolated from cell cultures of various sources. Orgenesis and ExcellaBio have now demonstrated the optimization and scale up of Bioxomes™, while generating consistent and repeatable results, including uniform particles sizes.
These Bioxomes have demonstrated the ability to fuse with cell membranes and deliver an intracellular cargo, in a similar manner to natural exosomes. Bioxomes can be sourced effectively from various cell cultures. These include mesenchymal stem cells, immortalized cells, immune cells and epithelial cells. When loaded with predesignated genetic material, proteins, signaling molecules and drugs, Bioxomes can carry selected therapeutic cargo inside the target cells, mimicking the natural membrane fusion capacity of EVs.
Vered Caplan, CEO of Orgenesis, said, “Orgenesis and ExcellaBio developing this new process represents a true breakthrough in the field of cell and gene therapy. It provides the ability to produce robust yields in only a few steps. We believe this process may unlock the potential for large-scale production of Bioxomes for a variety of therapeutic applications based on the natural intracellular trafficking abilities of exosomes/ EVs. In particular, we are aiming to develop promising new therapies, where we can deliver intracellular antiviral payloads, among dozens of other potential cell and gene therapies.”
