Summary:

      This is a multi-centre, randomised, placebo-controlled, double-blind, parallel-group
      comparative trial to be conducted in nocturia patients. The trial is designed to characterize
      the dose-response relationship of Minirin (desmopressin) Melt in order to establish correct
      dose recommendations in the target patient population. In particular, the trial is designed
      to link the duration of action to the clinical endpoint. Furthermore, the trial is designed
      to describe the safety of four different dose levels of desmopressin.
