Outcome Measures

Primary Outcomes (2)

• Occurrence of TEAEs

  An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. Treatment emergent adverse events (TEAEs) are adverse events not present prior to the pharamceutical product administration or an already present event that worsens either in intensity or frequency

  From Baseline Visit up to the End of Study Visit (Week 8)

• Occurrence of treatment-emergent SAEs

  A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose: Results in death Is life-threatening Requires inpatient hospitalisation or prolongation of existing hospitalisation Results in persistent or significant disability/incapacity, or Is a congenital anomaly/birth defect Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above

  From Baseline up to the End of Study Visit (Week 8)

Secondary Outcomes (3)

• Cmax

  From Day 1 (predose) up to the End of Study Visit (Week 8)

• AUC0-t

  From Day 1 (predose) up to the End of Study Visit (Week 8)

• AUCinf

  From Day 1 (predose) up to the End of Study Visit (Week 8)
