A new drug developed in New Zealand for the treatment of secondary progressive multiple sclerosis has been granted a patent in the United States.
The drug, called MIS416, was developed by biopharmacuetical company Innate Immunotherapeutics.
During a trial it resulted in 80 per cent of patients tested having a 30 per cent or greater improvement in at least one measure of MS-related clinical status.
Chief executive Simon Wilkinson said the US patent was a significant milestone because the US represents about 70 per cent of the worldwide MS market by revenue.
He said there were currently no drugs approved to effectively treat secondary progressive multiple sclerosis (SPMS).
