E.5 End points |
E.5.1 | Primary end point(s) |
Safety:
Occurrence of DLT.
Efficacy:
The ratio of PuFS over puncture-free interval at baseline.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Occurrance of DLT -Time of first drug related AE that occurs during 28 day period after first dose of Imalumab.
PuFS is defined as the time from the last dose of BAX69 to the first therapeutic paracentesis after that, or death, whichever occurs first.
Puncture-free interval at baseline is calculated as the time between the last 2 therapeutic paracenteses immediately before the first dose of BAX69. |
|
E.5.2 | Secondary end point(s) |
Efficacy:
The ratio of time to first paracentesis post-treatment over puncture-free interval at baseline
The change in ascites volume per unit time with treatment. The volume of ascites from the last dose of BAX69 to the first post-treatment therapeutic paracentesis per unit time will be compared to the volume of the last pre-treatment paracentesis per unit time. At each paracentesis, the volume of fluid
that can be removed safely (measured by ultrasound-guided paracentesis) to achieve close to dryness should be withdrawn, measured, and documented.
The changes in ascites-related symptoms (anorexia, nausea, early satiety, vomiting, abdominal pain, abdominal swelling, dyspnea, fatigue, swollen ankles, and heartburn) at baseline, weekly during the treatment period, and every 2 weeks during the Safety Follow-up period using a four-point Likert
scale (none, mild, moderate, and severe) for self-reporting.
Safety and Immunogenicity:
Occurrence of serious adverse events (SAEs) and/or TEAEs, regardless of causality or relationship to study drug graded using NCI CTCAE v4.03
Occurrence of binding and/or neutralizing anti-BAX69 antibodies following treatment with BAX69
PK:
BAX69 plasma PK parameters will be calculated, if estimable, using non compartmental methods and/or population PK modeling (including maximum observed concentration [Cmax], minimum observed concentration [Cmin], area under the concentration vs time curve [AUC], half-life [t1/2], apparent systemic clearance [CL/F], and volume of distribution [Vz/F])
QoL:
QoL will be assessed using EORTC QLQ-C30 |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Efficacy:
Time to first paracentesis post-treatment is calculated as the time between the last dose of BAX69 to subsequent first therapeutic paracentesis.
At each paracentesis, the volume of fluid that can be removed safely (measured by ultrasound-guided paracentesis) to achieve close to dryness should be withdrawn, measured, and documented
changes in ascites-related symptoms
at baseline, weekly during the
treatment period, and every 2 weeks during the Safety Follow-up period using a four-point Likert scale (none, mild, moderate, and severe) for self-reporting.
