The money will finance a Phase II clinical study to assess the safety, efficacy and tolerability of Opsona’s lead drug, OPN-305, in kidney transplant patients who are at high risk of delayed graft function - a form of post-transplant renal failure that can have very serious effect on patients.

The company, founded in 2004 as a spin-out from Trinity College Dublin, has already tested the drug's safety in healthy patients.
