- Secondary Outcome Measures
Name Time Method Incidence of Treatment-Emergent Adverse Events (TEAEs) From Baseline up to Day 35 An Adverse Event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment.
Incidence of Serious Adverse Events (SAEs) From Baseline up to Day 35 A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose:
* Results in death
* Is life-threatening
* Requires in patient hospitalization or prolongation of existing hospitalization
* Is a congenital anomaly or birth defect
* Is an infection that requires treatment parenteral antibiotics
* 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
