All subjects randomized set (RND): The RND consisted of all subjects in the subjects enrolled set (all subjects who provided informed consent for this trial.) who were randomized to trial medication. For analyses and displays based on RND, subjects were classified according to randomized treatment.

From the first drug administration until 43 days observation period after drug administration and up to 70 days safety follow up period

Regular investigator assessment at study visits. The safety analysis set was used which consisted of all subjects who provided informed consent and who received at least one dose of trial medication.
