(London UK and Boston USA, 21 September 2020) Immune Regulation Limited ("Immune Regulation"), a US and UK based clinical stage biotechnology company, today announced the closing of a Series B funding round led by Boston based Morningside Ventures ("Morningside"), alongside existing shareholders including London based 24Haymarket. The investment round is structured in two tranches and includes an option for Morningside to invest further capital at a step up to the initial two tranches. In addition, Immune Regulation has raised £6 million / $7.8 million of advance subscription funds from private investors led by Metellus AG which has been applied to the issue of shares.

The new funding will accelerate Immune Regulation's efforts to develop first-in-class drug product candidates that reset the immune system from a pro-inflammatory state to a balanced state, with the potential to achieve long term disease remission in autoimmune and allergic diseases.

"We have two clinical stage drug product candidates, '1805 and '1104, that have demonstrated impressive efficacy and safety data in phase 2a clinical studies on Rheumatoid Arthritis and Allergic Disease respectively and we are delighted to have Morningside as a partner to advance our programs," said Jonathan Rigby, U.S. based Group CEO of Immune Regulation. "This partnership with Morningside allows us to build our team in the U.S. and the UK as we prepare for multiple phase 2 clinical studies for both of our lead assets. In addition, we are progressing towards a clinical evaluation of '1104 to treat COVID-19 related Acute Respiratory Distress Syndrome (ARDS)."

"After extensive due diligence, Morningside concluded that Immune Regulation has drug products with significant potential to treat autoimmune and allergic diseases," said Isaac Cheng M.D. of Morningside Ventures. "I am pleased to be joining the Board of Directors and working with management to build a strong company that will deliver on the promise of its' drug product candidates."
