ListOutcomeTime frameDescription
SecondaryPart B: Number of Participants who do not Require Other Immune Thrombocytopenia (ITP) Therapy (non-transfusion) During the Part B Treatment PeriodUp to 52 weeksNumber of Participants who do not require other ITP therapy (non-transfusion) following the last BIVV009 dose will be assessed.
SecondaryPart B: Number of Participants who do not Require Platelet Transfusions During the Part B Treatment PeriodUp to 52 weeksNumber of Participants who do not require platelet transfusions during the Part B treatment period will be reported.
SecondaryPart B: Number of Participants who Experience any Bleeding Episode, Bleeding by Grade or Serious BleedingUp to 52 weeksNumber of participants who experience any bleeding episode, bleeding by grade or serious bleeding according to the International Working Group (IWG) Bleeding Assessment Tool (BAT) will be reported.
SecondaryPlasma Concentrations of BIVV009Approximately 97 weeksPlasma concentrations of BIVV009 will be assessed.
SecondaryMaximum Observed Plasma Concentration (Cmax) of BIVV009Approximately 97 weeksMaximum observed concentration of BIVV009 in plasma will be assessed.
SecondaryTime to Reach Maximum Observed Plasma Concentration (Tmax) of BIVV009Approximately 97 weeksTime to Reach Maximum Observed Plasma Concentration (Tmax) of BIVV009 will be assessed.
SecondaryArea Under the Concentration-time Curve (AUC) From Hour 0 to the last quantifiable time point (AUC [0-t]) of BIVV009Approximately 97 weeksAUC (0-t) is the area under the Concentration-time curve (AUC) from hour 0 to the last quantifiable time point of BIVV009.
SecondaryNumber of Participants With Anti-drug antibodies (ADAs) Against BIVV009Up to 97 weeksBlood samples will be collected to determine number of participants with anti-drug antibodies (ADAs) against BIVV009.
SecondaryComplement System Classical Pathway Levels as Measured by WIESLAB AssayUp to 97 weeksInhibition by BIVV009 of the complement system classical pathway measured by the WIESLAB assay.
SecondaryTotal Complement (CH50) LevelsUp to 97 weeks
Complement CH50 is a blood test that helps us determine whether protein abnormalities and deficiencies in the complement system are responsible for any increase in autoimmune activity. It will be assessed using complement assays.
SecondaryTotal Complement Factor C4 LevelsUp to 97 weeksTotal C4 Levels will be assessed in plasma using complement assays.
SecondaryC1 Complex Components: C1qUp to 97 weeksC1q Levels will be assessed in plasma using complement assays.
SecondaryThrombopoietin LevelUp to 97 weeksThrombopoietin level will be assessed in plasma using complement assays.
