General information about the trial
|
|||
Main objective of the trial |
Part A:
To demonstrate the pharmacokinetic (PK) non-inferiority of BAY81-8973 as compared to sucrose formulated successor Kogenate (Kogenate FS) using bioequivalence criteria following single dose administration.
Part B:
To demonstrate the efficacy and safety of BAY81-8973 for the treatment of bleeds and prophylaxis.
Part C:
To demonstrate efficacy for hemostasis during major surgery.
|
||
Protection of trial subjects |
The conduct of this clinical study met all local legal and regulatory requirements. The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and the International Conference on Harmonization guideline E6: Good Clinical Practice. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.

Notes [1] - Period 1 is not the baseline period. It is expected that period 1 will be the baseline period. Justification: The study was conducted in three different parts, as Part A, Part B and Part C. Hence, the baseline period of all enrolled subjects in a study was created to publish the baseline characteristics data. |

Adverse event reporting additional description |
The objective of Part C was efficacy assessment of surgery hemostasis, not safety assessment. It was allowed to include the same subject for several surgeries and for each surgery the subject was assigned a new subject number. Due to this approach, one subject with 3 surgeries was analyzed as 3 different subjects, therefore the number at risk is 7.

Amendment 1, specified the following modifications:
1. The regulatory agencies requested clarification regarding the surgery indication, such as a definition of the surgery types, safety data required prior to surgery, and evaluation times of the surgery outcome data during the study.
2. The study criteria were clarified as >= 10 surgeries in >= 10 subjects.
3. The PK blood sampling scheme was revised to include an additional timepoint, 30 h post-injection, to comply with the regulatory agencies’ request for additional timepoints.
4. Amendment 1 specified that following randomization, subjects were to be supplied with and were to use only antihemophilic factor (recombinant), Kogenate
FS where there was a need for FVIII treatment, and the investigational product, BAY81-8973, was not provided.
5.The one-time titration and change in dose per injection was removed, thus, a fixed, consistent dose was to be administered for each injection.
6. The injection time for PK (Part A) and for in vivo recovery (Part A and Part B) was changed to 10 min instead of 5-10 min. Treatment interruption of prophylaxis treatment was revised as not permitted. The dosage range for prophylaxis treatment was clarified as occurring in 5 IU/kg increments over the range of 20-40 IU/kg (ie, 20, 25, 30, 35, or 40 IU/kg), administered 2-3 times per week, at the investigator’s discretion.
7. Editorial changes in primary objective and changes in most efficacy objectives to reflect that efficacy data will be combined with Protocol 2009-012150-20 (14319) for statistical analysis. Change in secondary objective of the study from “demonstrate the non-inferiority of BAY 81-8973 based on potency determinations (CS/EP vs CS/ADJ)” to “compare BAY 81-8973 based on potency determinations (CS/EP vs CS/ADJ) as measured by in vivo recovery”. |

Amendment 5, specified the following modifications:
- The inclusion criterion for current inhibitor antibody was clarified and the washout time was revised to be consistent with a washout period of 3 days specified throughout the protocol. In addition, the inhibitor history inclusion criterion was corrected from >1.0 to 1 BU. In the original protocol, the inhibitor inclusion criterion was 1 Bethesda unit (BU). It was changed in error to >1 BU in Amendment 1. In Amendment 5 it was corrected back to 1 BU.
- The exclusion criterion for CD4 lymphocyte cell count (< 400 cells/microliter) was revised to be consistent with previous studies (< 250 cells/microliter). In addition, the exclusion criterion of portal vein hypertension was clarified as “significant portal vein hypertension in the judgement of the investigator”.
- The number of subjects to be enrolled into Part A of the protocol was revised from 16 to up to 30.
- Since it was not required that Kogenate was to be administered within 15 minutes (min) of surgery, this condition was deleted. Also, since a urine dipstick test was not performed (only urinalysis), the dipstick test was deleted.
- The treatment administration time was changed from 5 – 10 min to 1 – 15 min. This change was made to be consistent with the product labeling for Kogenate FS.
- Concomitant therapy was revised to allow subjects with arthritis to receive treatment with NSAIDS. |

Amendment 6, specified the following modifications:
- The definition for severe hemophilia A in the inclusion criteria was clarified and expanded to allow subjects with previous medical history documentation of < 1% FVIII:C, determined by the one-stage clotting assay, to be included in the trial without further testing/confirmation of severe hemophilia A if the screening result turned out to be >=1%.
- The number of surgeries (across both studies 12954 and 14319) was increased from “>=10 surgeries in >= 10 subjects” to “ >=15 surgeries in >=15 subjects”, and the classification of surgery types was clarified (“at least 8 must be classified as major surgical procedures”) to enable a more thorough evaluation of the safety and efficacy of BAY 81-8973 in the surgical setting.
- To further ensure subject safety, the requirement was added that BAY81-8973 should not be supplied for use in the surgical setting until at least 20 bleeding events (across both studies) had been assessed to ensure the hemostatic activity of BAY81-8973. It was further specified that all sites were to be informed by the Sponsor when surgical treatment using BAY81-8973 was allowed to commence.
- Editorial revision of the change regarding dipstick urine test.
- Since the 3-day washout of FVIII applied to both Part A and B and not just Part A, the appropriate exclusion criterion was revised. "Any subject in Part A who cannot forego at least 3 days without receiving FVIII before the PK sessions for washout purposes." was changed to "Any subject who cannot forego at least 3 days without receiving FVIII for washout purposes. |

Amendment 7, became effective after 28 subjects had started treatment. It specified the following modification:
Addition of “known hypersensitivity against mouse protein” as an exclusion criterion. |

13 Jan 2011 |
Amendment 8, specified the following modifications:
- The study objectives of Part B of the study were reorganized to ensure that the primary and secondary study objectives included objectives for results of this study alone, and a separate category, “addendum objectives”, was added to include objectives for the pooled results of this study and Study 2009-012150-20 (14319). Importantly, no Part B objectives were deleted or significantly revised.
- The highest dosage was increased from 40 IU/kg to 50 IU/kg in Part B of the study, in order to account for standard of care of some centers who use this dose as a standard prophylaxis dosing.
- A pharmacogenetic sample for FVIII genetic analysis was added which allows the genetic analysis of FVIII polymorphism in different ethnic groups participating in this trial.
- If another product had to be used during the study to control the bleed (according to the local standard of care), the product was no longer required to be a marketed recombinant FVIII product, and could be another marketed FVIII product as not all participating sites were using recombinant products as standard of care.
- Visit 4 and Visit 5 were combined into one visit, Visit 4/5, because 2 visits within 3 days were thought to be very difficult to arrange for young subjects who are in an active life, and could be a barrier for recruitment. The recovery required at Visit 4, the end of the first period, was changed to Visit 3. |

Amendment 9, specified the following modifications:
- Additions to study objectives (“additional objectives”), description of Part C (“Major Surgery Arm”), inclusion criteria, and other protocol sections to account for major surgeries.
- Introduction of the extension period (treatment beyond the 1-year treatment period for 1 further year) and a detailed description of this in the appropriate protocol sections. |
