Primary Outcome Measures
NameTimeMethod
Percentage of participants with with treatment-emergent adverse Events (TEAEs) leading to withdrawal from the studyFrom Baseline (Day 1) until Safety Follow-Up (up to Week 180)

Treatment-emergent adverse events (TEAEs) are any untoward medical incidence in a subject during administered study treatment, whether or not these events are related to study treatment.

Percentage of participants with treatment-emergent adverse events (TEAEs) during the studyFrom Baseline (Day 1) until Safety Follow-Up (up to Week 180)

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. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Percentage of participants with serious adverse events (SAEs) during the studyFrom Baseline (Day 1) until Safety Follow-Up (up to Week 180)

A serious adverse event (SAE) is any untoward medical occurrence that at any dose:

* Results in death

* Is life-threatening

* Requires in patient hospitalisation or prolongation of existing hospitalisation

* Is a congenital anomaly or birth defect

* Is an infection that requires treatment with parenteral antibiotics

* Other important medical events which based on medical or scientific judgement may jeopardise the patients, or may require medical or surgical intervention to prevent any of the above
