Kairos Biotech Ltd announced today that they have received follow on funding of €1m from Dutch entity EchiumBio Holding BV. EchiumBio received 38.1% share of a fully diluted equity pool of the company.

Kairos Biotech management comprises CEO & founder, Dr Mike Bunce, R&D director Ben Passey, Senior Scientist Hayley Hogan and investor director Dr Wietse Mulder.

Kairos Biotech’s development laboratory operates from Wrexham University’s OpTIC Technology Centre in St Asaph, North Wales.

The transaction was executed with legal support from Herke van Hulst and Angela Saldanha at Osborne & Clarke in Amsterdam and Catherine Williams from Keystone Law in London.

The follow-on investment came after the company achieved significant milestones in developing its novel molecules for transplant diagnostics and applications in targeted immunotherapy.

Our approach in transplantation

Successful kidney and other solid organ transplants need to avoid immunological rejection to succeed. Unfortunately, many patients have pre-formed anti-donor T and B cells that restrict the opportunities for transplant. Some patients may wait years for a transplant opportunity due to deleterious anti-donor immunological responses.

Kairos Biotech aims to improve transplant success by developing small molecules that are suitable for both improving diagnostics, and molecularly enhanced to modulate or remove immunological anti-donor responses. We will demonstrate that these ‘designer immunosuppressive molecules’ can interfere and remove the anti-donor responses in a highly-specific and possibly permanent way. This transplant tolerance is expected to be highly beneficial for the transplant of highly sensitized patients. This will enable shorter waiting times for transplant, and potentially improved transplant survival.
