Design outcomes

Primary

MeasureTime frameDescription
Occurrence of TEAEsFrom Baseline Visit up to the End of Study Visit (Week 8)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
Occurrence of treatment-emergent SAEsFrom Baseline up to the End of Study Visit (Week 8)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

Secondary

MeasureTime frameDescription
CmaxFrom Day 1 (predose) up to the End of Study Visit (Week 8)Cmax: Maximum serum concentration
AUC0-tFrom Day 1 (predose) up to the End of Study Visit (Week 8)AUC0-t: Area under the curve from 0 to the time of the last quantifiable concentration
AUCinfFrom Day 1 (predose) up to the End of Study Visit (Week 8)AUCinf: Area under the curve from 0 to infinity
