Percentage of Participants With at Least One Adverse Event (AE) During the Study
Time Frame: From screening (Day -28 to Day -2) up to end of study (EOS) visit day 20 (+/-1)
|
An AE was any untoward medical occurrence in a patient or clinical investigation study participant administered a pharmaceutical product that did not necessarily have a causal relationship with this treatment.
An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

From screening (Day -28 to Day -2) up to end of study (EOS) visit day 20 (+/-1)
|
Percentage of Participants With at Least One Serious Adverse Event (SAE) During the Study
Time Frame: From screening (Day -28 to Day -2) up to end of study (EOS) visit day 20 (+/-1)
|
A SAE was any untoward medical occurrence that at any dose resulted in death, was life-threatening, required in patient hospitalization or prolongation of existing hospitalization, was a congenital anomaly or birth defect, was an infection that requires treatment parenteral antibiotics or other important medical events which based on medical or scientific judgement could jeopardize the patients, or could require medical or surgical intervention to prevent any of the above.
