E.5 End points |
E.5.1 | Primary end point(s) |
A. Percentage of subjects with solicited local adverse events (AEs)
An adverse event is any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Solicited local adverse events assessed are injection site pain, erythema, swelling, induration.
Any erythema, swelling and swelling is defined as a symptom with a surface diameter equal or greater than 25 millimeter.
B. Percentage of subjects with solicited systemic adverse events
Solicited systemic adverse events assessed are (i.e., fever [temperature ≥ 38.0°C/100.4°F], nausea, fatigue, myalgia, arthralgia, headache).
C. Percentage of subjects with any unsolicited adverse events, Serious Adverse Events (SAEs), AEs leading to withdrawal and medically attended AEs .
Unsolicited adverse events are defined as any AE reported in addition to those solicited during the clinical study. Also, any ‘solicited’ symptom with onset outside the specified period of follow-up for solicited symptoms are reported as an unsolicited adverse event.
SAEs are any untoward medical occurrence that result in death, are life-threatening, require hospitalization or prolongation of existing hospitalization, result in disability/incapacity and is a congenital anomaly/birth defect in the offspring of a study subject
Medically attended AEs are symptoms or illnesses requiring hospitalization, or emergency room visit, or visit to/by a health care provider.
D. Percentage of subjects with any SAEs, AEs leading to withdrawal and medically attended AEs.
Serious adverse events, AEs leading to withdrawal and medically attended AEs throughout the study period are assessed.
E. Percentage of subjects with adverse events of special interest (AESI).
AESIs are predefined (serious or non-serious) adverse events of scientific and medical concern specific to the product or program, for which ongoing monitoring and rapid communication by the investigator to the sponsor can be appropriate, because such an event might warrant further investigation in order to characterize and understand it.
