Phase

Phase

Das Stadium einer klinischen Studie, in der ein Medikament oder ein biologisches Produkt untersucht wird, basierend auf Definitionen, die von der U.S. Food and Drug Administration (FDA) entwickelt wurden. Die Phase richtet sich nach dem Ziel der Studie, der Anzahl der Teilnehmer und anderen Merkmalen. Es gibt fünf Phasen: Frühe Phase 1 (früher als Phase 0 aufgeführt), Phase 1, Phase 2, Phase 3 und Phase 4.

Number of CMV Seronegative Subjects With Appearance of Anti-CMV Tegument Protein IgG Antibodies in Serum.
Zeitfenster: From study Month 0 to Month 36
This outcome was part of the assessment of occurrence of CMV primary infections determined in all seronegative subjects, on samples collected during the 4-month site visits until study conclusion. A seronegative subject is a subject for whom anti-CMV IgG antibodies were not detected in serum sample collected at Month 0. CMV primary infection is defined as the first infection with CMV in subjects who were seronegative at enrollment.
