Welcome to Capsular Technologies

Micro-hydrogel vaccine delivery platform enabling

controlled-release of bioactive material

Capsular Technologies is a Melbourne based startup offering a unique vaccine encapsulation solution, turning multiple-shot injection into a single-shot immunology regime.

About Capsular

We are an Australian biotech company researching and developing a unique vaccine delivery platform by encapsulating the antigen in a controlled-release biopolymer gel formulation turning multiple-shot injection into a single-shot injection regime with the same immunological protection. 

As part of the wind up of the Polymers CRC, all of the technology from its encapsulation research program was assigned into the spin-off company Capsular Technologies P/L (‘Capsular’). Capsular has three strong patent applications, at various stages of development.

  • "Injectable composition for delivery of a biologically active agent" WO2017177265

  • "Biopolymer hybrid gel-depot delivery system"  WO2011003155

  • "Vaccine Composition" WO2019173871

Headquartered in Melbourne, Victoria, Capsular focuses on research and commercialisation of single injection micro-hydrogel biopolymers vaccine delivery platform. We have strong R&D capability across a network of research providers and collaborators including leading scientists at the Swinburne University of Technology and the University of Queensland.

Our Technology

The major issue with current veterinary vaccines is the fast clearing from the body after vaccination, which prevents the development of complete protective immune response, necessitating one or multiple booster shots to induce protection. Currently, there are no platform technologies commercialised that deliver single-dose sustained released of inactivated vaccines based on killed or subunit antigens due to poor antigen stability and the difficulty in obtaining unconventional release kinetics upon vaccine administration.

Capsular overcomes this limitation by encapsulating the vaccine antigen in micro-hydrogel. These micro-hydrogel form in situ in water droplets within oil adjuvant, giving a complex micro-hydrogel in emulsion structure. The water-in-oil micro-hydrogel emulsion modulates the release of antigen to produce a cascade of immune responses, allowing for the development of a protective immune response without the need for the booster shots. The encapsulation of the antigen relies on tailored electrostatic interactions and physical entrapment within the crosslinked hydrogel. Whereas the modulated release of the antigen relies on the diffusion and the biodegradation of the hydrogel in the body.

Steve Wright

EMBA, Grad. Dip. Mgt,  AFIML

Company Secretary

Steve has had a long and successful career working in science and technology based organisations that have predominantly focused on research, innovation and commercialisation/utilisation.  This has often been combined with an educational thrust that has significantly enhanced and grown Australia’s capabilities.

 

During this time Steve has undertaken strategic, facilitative and tactical activities in various roles including business manager, company secretary, director and CEO of management and spin-off companies.  The formation and early stage development of Capsular Technologies Pty Ltd is the most recent spin-off company in which he has been involved and he is very excited about the longer-term prospects for this company and the technology platform which it owns.

 

An undergraduate degree in economics from ANU and postgraduate management qualifications from UNSW have provided a sound basis for effectively addressing real world challenges.
