General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study is to assess the safety and tolerability of Octaplas in the pediatric population by monitoring serious adverse events (SAEs), adverse drug reactions (ADRs), thrombotic events (TEs), thromboembolic events (TEEs) and hyperfibrinolytic events (HFEs), including laboratory parameters for metabolic derangements, renal function, and hematologic implications.
|
||
Protection of trial subjects |
This trial was conducted in accordance to the principles of ICH- GCP, ensuring that the rights, safety and well-being of patients are protected and in consistency with the Declaration of Helsinki.
Inclusion and exclusion criteria were carefully defined in order to protect subjects from contraindications, interactions with other medication and risk factors associated with the investigational medicinal product.
Throughout the study safety was assessed, such as of monitoring of ADRs, thrombotic events (TEs), thromboembolic events (TEEs), Hyperfibrinolytic event (HFEs) of causality and documentation of concomitant medication.

Dosage and administration details |
Octaplas was used per the approved labeling for the product. The number of infusion episodes and volume of Octaplas administered within the 72-hour treatment period depended on the clinical setting. The infusion rate of Octaplas was not to exceed 0.020-0.025 mmol citrate per kg per minute. The minimum dose of the first infusion was 10 mL/kg or one unit unless a lower dose was medically justified.

Date |
Amendment |

17 Mar 2015 |
Amendment #4 was issued to primarily update conditions for storage and use, since new stability data had been approved by FDA. |
||
18 Mar 2015 |
Amendment #3 was issued to primarily apply several enhancements. |
||
03 Feb 2016 |
Amendment #5 was issued to primarily apply several enhancements. |
||
09 Sep 2016 |
Amendment#7:
- Use of Octaplas to Prime Cardiopulmonary Bypass (CPB):Language was added into the protocol in order to explain that patients who undergo cardiac surgery and receive Octaplas solely for the priming of the CPB circuit are qualified for enrollment and will be part of the full analysis set
- Reduction of Age Categories
-The end of study timeline has been revised |
||
19 Nov 2016 |
Amendment#8: The timing of the pre-and post-infusion samples for patients on cardiopulmonary-bypass was clarified in the protocol. |
||
29 Nov 2017 |
Amendment#9: Given that there have been no safety concerns thus far in all age groups and since most patients meeting the eligibility criteria have the required surgery at an early stage in their life, i.e. 0-2 years, the planned enrollment for the 2-16 year age category was changed from a minimum of 17 patients to a minimum of 13 patients. |
