Company Announcements

• Presentations demonstrate the potential of AdoShell^® for allogenic cell therapy in diabetes without immunosuppression, by delivering pancreatic human islets or iPSCs¹
• New preclinical data support AdoShell^® Islets progression toward First-In-Human clinical trial submission in 2025
• Data to be presented at the American Diabetes Association’s (ADA) 85^th Scientific Sessions, the International Pancreas and Islet Transplant Association (IPITA) World Congress, the European Islets Study Group (EISG), and the International Society for Cell & Gene Therapy (ISCT) Annual Meeting

LYON, France--(BUSINESS WIRE)--Apr. 28, 2025-- Regulatory News:

Adocia (Euronext Paris: FR0011184241 – ADOC), a clinical-stage biopharmaceutical company focused on the research and development of innovative therapeutic solutions for the treatment of diabetes and obesity (the “Company”), today announced the latest preclinical data from its innovative AdoShell^® technology platform have been selected for presentations at four upcoming scientific conferences.

AdoShell^® Islets is an innovative immunoprotective hydrogel designed to encapsulate pancreatic islets, with the goal of curing diabetes through cell therapy without requiring immunosuppression. This semi-permeable hydrogel allows the diffusion of insulin and glucose, while preventing the infiltration of antibodies and immune cells that would lead to graft rejection. Currently, to prevent this normal body reaction, every allogeneic transplant patient must take immunosuppressive drugs on a chronic basis, with significant side effects. AdoShell^® is easily implantable and fully retrievable via laparoscopy.

The new data to be presented by Adocia notably disclose the success of the scale-up to deliver the therapeutic dose for the first-in-human study, which is planned to be submitted with the regulatory authorities in 2025.

In addition, new in vitro and in vivo data to be presented confirm the compatibility of AdoShell^® with stem cell-derived islets, notably their ability to mature into insulin producing cells within AdoShell^®. The integration of these stem cell-derived islets into our technology represents a key step toward broader access to type 1 diabetes treatment through cell therapy, without the need for immunosuppression.

Adocia envisions that AdoShell^® could be applied beyond pancreatic cells to other cell types. Data with primary and differentiated stem cells for the release of various therapeutic molecules other than insulin will also be presented, illustrating the possibility to make AdoShell^® a technology platform.
