Our BEPO® technology allow us to develop long-acting treatment

Our patented BEPO® technology makes it possible to control and guarantee the regular delivery of a drug at the optimal therapeutic dose for several days, weeks or months. At the time of the injection, the BEPO® technology forms a deposit of polymers of a few millimeters under the skin for a systemic action, or locally for a targeted action. The deposit diffuses the active ingredient by resorbing for the desired duration, like a mini pump that would be injectable and bio-resorbable.

In many indications

Once a medical need has been identified, the potential of the product validated and its technical feasibility evaluated positively, the MedinCell team creates a prototype that meets the targeted specifications, in particular the duration of action and the dose of active ingredient to be released. For each product, a new polymer combination is created, making each formulation unique and exclusive.

BEPO® Technology

BEPO ®
inside

BEPO® is composed of a solution of diblock (DB) and triblock (TB) copolymers containing hydrophilic and water-soluble blocks (polyethylene glycol – PEG) linked with hydrophobic and amorphous blocks (Poly(D,L-lactic acid) – PLA) which precipitate in forming a depot when exposed to an aqueous environment.
The API is entrapped within the polymer matrix and is released thereafter by difusion and following polymer degradation. The hygroscopy and consequently the API release kinetics from the depots can be fine tuned by adjusting the hydrophilicity of the DB and TB and their relative ratio.

PEG

PEG (polyethylene glycol) block

  • Also known as polyethylene oxide (PEO)
  • Commercially available over a wide range of MW
  • Hydrophilic, water soluble

PLA

  • PLA block
  • Poly (D,L-lactic acid) or poly (D,L-lactide)
  • Prepared by polymerization (ROP) of cyclic (D,L)-lactide monomer
  • Amorphous, hydrophobic
  • Biodegradable macromolecule (through hydrolysis)

Advisory Board

Prof. dr. ir. Tina Vermonden

Prof. dr. ir. Tina Vermonden Utrecht University, The Netherlands
Biomaterials for Regenerative Medicine and Drug Delivery

After obtaining a PhD in Organic Chemistry at Wageningen University, Tina Vermonden moved to Utrecht University in 2005 to join the Pharmaceutics division as a postdoctoral researcher. Since then, her research has focused on biomaterials science, which is a multidisciplinary field of research encompassing elements of medicine, biology, chemistry, and materials science. In 2020, she was appointed as full professor. Tina’s group focusses mainly on the development of polymeric materials that are suitable as either protein or drug delivery matrices or as scaffolds for regenerative medicine. Important parameters are biocompatibility, degradability and stability in time under physiological conditions.

ScD Prof. PhD Bernhardt L. Trout

Bernhardt L. Trout is the Raymond F. Baddour, ScD, (1949) Professor of Chemical Engineering at MIT. He received his S.B. and S.M. degrees from MIT and his Ph.D. from the University of California at Berkeley. In addition, he performed post-doctoral research at the Max-Planck Institute.

Trout’s research focuses on the development of advanced manufacturing processes and rational tools for formulation and product design, primarily liquid formulations, but also lyophilized formulations. A major aspect of his research focuses on developing both microscopic and macroscopic models to design stable formulations efficiently. In 2007, with several colleagues from MIT, he set up the Novartis-MIT Center for Continuous Manufacturing, a $85 million partnership with the objective of transforming pharmaceutical manufacturing. Among other outputs, this led in 2011 to the first end-to-end fully integrated and automated pharmaceutical process (bench scale). He was also Co-Chair of the Singapore-MIT Alliance Program on Chemical and Pharmaceutical Engineering. In addition to Novartis, he has worked with many other pharmaceutical companies in research or consulting. He has also developed a host of computational methods for the design of biologics products taking into account developability and manufacturability and continues to work in the field of continuous manufacturing. He recently started a project with the FDA on a continuous lyophilization process. In addition, he is Co-Chair of the International Symposium on Continuous Manufacturing of Pharmaceuticals. He has published over 200 papers and has 18 patents issued or pending.

Prof. PhD Juergen Siepmann

Juergen Siepmann studied pharmacy and did his Ph.D. at the Freie Universitaet Berlin, Germany. Since 2004 he is Professor of Pharmaceutical Technology at the University of Lille, France.

His research focuses on controlled drug delivery systems, in particular on the elucidation of the underlying mass transport phenomena, mathematical modeling and the optimization of the devices. He is heading the Inserm (French National Institute of Health and Medical Research) research group “Advanced Drug Delivery systems”, counting about 50 members.

Since 2010 he serves as president of the APGI (https://www.apgi.org), and since 2016 as Editor-in-Chief of the “International Journal of Pharmaceutics” (https://www.journals.elsevier.com/international-journal-of-pharmaceutics).

Prof. PhD Sébastien Lecommandoux

Sébastien Lecommandoux received in 1996 his PhD in Physical Chemistry from the University of Bordeaux. After a postdoctoral experience at the University of Illinois (UIUC, USA) in the group of Prof. Samuel I. Stupp, he started his academic career at the Laboratoire de Chimie des Polymères Organiques as Associate Professor in 1998 and was promoted to Full Professor at Bordeaux INP in 2005. He is currently Director of the Laboratoire de Chimie des Polymères Organiques (LCPO-CNRS) and is leading the group “Polymers Self-Assembly and Life Sciences”. His research interests include polypeptide and polysaccharide-based block copolymers self-assembly, the design of polymersomes for drug-delivery and theranostic, as well as biomimetic approaches toward design of synthetic viruses and artificial cells.
