PRIMARY outcome

Timeframe: 14±1 days after the drug administration (up to last visit time point)

Population: Safety population: subjects who received at least one dose of PBTZ169. The population was used for the analysis and evaluation of the demographic and other baseline data and all safety parameters including AEs, physical examination, evaluation of the vital signs, previous and current therapy, ECG, all laboratory tests

The frequency of adverse events for which a relationship to the test drug PBTZ169 was noted
