Primary Purpose: Treatment
Official Title: A Double-Blind, Randomized, Placebo Controlled, Single Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetic and Pharmacodynamic Profiles of SLV354 After Oral Dose Administration in Healthy Adult Male Subjects

Further study details as provided by Abbott:

Primary Outcome Measures:
  • Safety and tolerability assessments including adverse events, clinical laboratory tests, ECG and vital signs (Part A) [ Time Frame: 1 week after each dose level ]
  • Safety and tolerability assessments including adverse events, clinical laboratory tests, ECG and vital signs (Part B) [ Time Frame: 2 weeks after each dose ]

Secondary Outcome Measures:
  • Pharmacokinetic parameters (AUC and Cmax) after single ascending oral dosing of max. 8 doses of SLV354 ranging from 20 to 1250 mg (Part A) [ Time Frame: 1 week after each dose level ]
  • Pharmacodynamic variables (EEG, Cognitive tests, Questionnaires, plasma hormones ACTH / cortisol / TSH / T3 / T4) (Part A) [ Time Frame: 1 week after each dose level ]
  • Pharmacokinetic parameters (AUC and Cmax) after single oral dosing of 2-4 doses of SLV354 chosen (Part B) [ Time Frame: 2 weeks after each dose ]
  • Pharmacodynamic variables : Cognitive tests, Questionnaires, fMRI) (Part B) [ Time Frame: 2 weeks after each dose ]
