Paradigm Biopharmaceuticals (ASX:PAR) said it received US ethics approval to start a phase 3 trial of injectable pentosan polysulfate sodium (iPPS) for the potential treatment of knee osteoarthritis, according to a Thursday filing with the Australian bourse.
The approval, granted by a centralized institutional review board, allows the company to start the trial across the US, the filing said.
The first patient is expected to be enrolled in the third quarter of the year, the filing added.
