Clinical Trials in Poland

The most recently authorised trials on the EU Clinical Trials Information System (CTIS), the single register for every trial run under the EU Clinical Trials Regulation (536/2014). CTIS holds a far larger historical archive than any one list can usefully show — this register states both numbers rather than picking one.
