General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study was to prospectively document the exposure to
IMMUNINE and to monitor FIX inhibitors over a period of approximately 20 – 50 EDs
while receiving prophylactic treatment in up to 50 PTPs aged 12 – 64 years and
approximately 20 pediatric PTPs up to 11 years of age with severe (FIX level < 1%) or
moderately severe (FIX level ≤ 2%) hemophilia B who were planned to enter BAX 326
pivotal study 250901 or BAX 326 pediatric study 251101, provided all eligibility criteria
had been met.
|
||
Protection of trial subjects |
The study was conducted in accordance with the principles set forth in Title 21 of the US Code of Federal Regulations (CFR), parts 50, 54, 56, 312 and 314, International Committee on Harmonisation (ICH) Guidelines for Good Clinical Practice (GCP), and applicable local and national regulatory requirements.

Hemostatic efficacy rating of IMMUNINE at resolution of bleeding | ||||||||||||||||||||||||||||||||
End point description |
Excellent: Full relief of pain and cessation of objective signs of bleeding (e.g., swelling, tenderness, and decreased range of motion in the case of musculoskeletal hemorrhage) after a single infusion. No additional infusion is required for the control of bleeding. Administration of further infusions to maintain hemostasis
would not affect this scoring.
Good: Definite pain relief and/or improvement in signs of bleeding after a single infusion. Possibly requires more than 1 infusion for complete resolution.
Fair: Probable and/or slight relief of pain and slight improvement in signs of bleeding after a single infusion. Required more than 1 infusion for complete resolution.
None: No improvement or condition worsens.

Incremental recovery (IR) was measured at Week 4, Week 12, Week 26, and Termination. Time points for blood sampling for IR were 0-30 minutes prior to infusion and 30 minutes ± 5 minutes post-infusion.
Pediatric subjects (<= 11 years) were 4 (Week 4); 2 (Week 12 and Week 26); 0 at Termination. '9999999999' was entered as result for termination since the results cannot be left blank.
Adolescent/adult subjects (>= 12 years) were 27 (Week 4); 20 (Week 12); 7 (Week 26); 18 (Termination).
