General information about the trial
|
|||
Main objective of the trial |
The purpose of the study is to assess the safety, efficacy and pharmacokinetics of 2 separate dose regimens (75 μg/kg and 225 μg/kg) of Coagulation Factor VIIa (Recombinant) for the treatment of bleeding episodes in hemophilia A or B patients with inhibitors to Factor VIII or IX in 13 patients ( birth to <6 years old), and 12 patients (≥6 years old to <12 years old).
|
||
Protection of trial subjects |
This study was conducted in compliance with good clinical practice (GCP) as described in the International Conference on Harmonisation (ICH) document “Guidance for Industry-E6 Good Clinical Practice: Consolidated Guidance” dated April 1996 and its addendum dated November 2016. These practices were consistent with the principles stated in the Declaration of Helsinki (October 2013 revised version). All other applicable regulations were followed.

Good: Symptoms of bleed (e.g., swelling, tenderness, and decreased range of motion in the case of musculoskeletal
hemorrhage) had largely been reduced by the treatment, but had not completely disappeared. Symptoms had improved
enough to not require more infusions of the study drug.
Excellent: Full relief of pain and cessation of objective signs of bleed (e.g., swelling, tenderness, and decreased range
of motion in the case of musculoskeletal hemorrhage). No additional infusion of study drug was required.

Categories of Response to Treatment are Described as Follows:
None: No noticeable effect of the treatment on the bleed or worsening of patient's condition. Continuation of treatment
with the study drug was needed.
Moderate: Some effect of the treatment on the bleed was noticed, e.g., pain decreased or bleeding signs improved, but
bleed continued and required continued treatment with the study drug.
Good: Symptoms of bleed (e.g., swelling, tenderness, and decreased range of motion in the case of musculoskeletal
haemorrhage) had largely been reduced by the treatment, but had not completely disappeared. Symptoms had
improved enough to not require more infusions of the study drug.
Excellent: Full relief of pain and cessation of objective signs of bleed (e.g., swelling, tenderness, and decreased range

04 Aug 2015 |
This amendment included the following key changes: -Timing around treatment for severe bleeding episode was added. -Clarifying statement regarding enrollment of patients <12 years old following DMC review of PK, safety and efficacy data. -Table of Total Amount of Blood Taken during the study added to ensure awareness of the maximum allowable blood volume collection in pediatric patients. -Added exclusion criterion #10: hypersensitivity to the active substance or excipients. - Added information regarding required reporting periods for SAEs. -Added weight and dose adjustment at each 6 week visit due to pediatric patient weight fluctuation. -Added signs and symptoms of thromboembolic events as an additional safety precaution unrelated to any safety concern. -Several minor corrections were also made. This amendment was not implemented. |

This amendment includes the following key changes: -The LR769 surgical study (LFB-FVIIa-008-14) could only include patients younger than 12 years of age if sufficient PK, efficacy and safety data becomes available and after the DMC has reviewed these data and determined the appropriateness of including this population. This information was included for clarification that patients <12 years old would not be enrolled into the surgical study from this pediatric study until review of PK, safety and efficacy data was reviewed by the DMC. |
