Neuren Pharmaceuticals (ASX:NEU) has requested an immediate trading halt on its shares, pending an update regarding US Food and Drug Administration (FDA) feedback on its NNZ-2591 treatment for Pitt Hopkins syndrome and hypoxic-ischemic encephalopathy, according to a Wednesday Australian bourse filing.
The trading halt will remain in place until either the market opens on Friday or the company releases an update, whichever comes first, the filing added.
