DelSiTech Ltd Receives Funding for the Stabilization of Viral Vaccines

Turku, Finland – 24 October 2018: DelSiTech Ltd, a Finnish drug delivery and drug development company, today announced significant grant funding to support the development of thermostabilized viral vaccines from the Bill & Melinda Gates Foundation.


DelSiTechTMSilica Matrix is an advanced, sustained and controlled release delivery technology for administration of injectable, implant and topical eye drop dosage forms. One important feature of DelSiTech’s technology is the ability to confer thermostability to viruses over long periods of time, over years.


“To ensure the optimal potency of vaccines, storage conditions need careful attention and maintenance of the cold chain is especially important in developing countries, where outdoor temperatures can easily exceed 40°C,” said Dr. Lasse Leino, CEO of DelSiTech. “We are delighted and honoured to receive funding from the Bill & Melinda Gates Foundation for such an exciting and critical program.”

This is an advanced delivery technology for parenteral and local administration of injectable and implant dosage forms as well as eye drops. The proprietary technology is based on silica (SiO2) matrix into which the molecule or therapeutic agent of interest is embedded using a process called sol-gel. The resulting Matrix is non-porous, biocompatible and it can be designed to biodegrade by matrix dissolution at the desired rate to ensure a tightly controlled release of the active substance over periods of days up to many months or a year.


One important feature of DelSiTech’s technology is the ability to confer thermostability to viruses and therefore, overcome the need for storage at, for example, -80°C. It is estimated that 50% of lyophilized vaccines are discarded annually, and temperature instability is an appreciable contributing factor in this.
