General information about the trial
|
|||
Main objective of the trial |
The primary efficacy objective of the study is to evaluate the effect of IV iron isomaltoside 1000 compared with placebo in first-time female donors with p-ferritin below 60 µg/L.
The safety objective of the study is to evaluate the safety of IV iron isomaltoside 1000 compared to placebo.
|
||
Protection of trial subjects |
The protocol and amendments were approved by local ethics committees/Institutional Review Boards and competent authorities. The trial was conducted in accordance with good clinical practice and the Declaration of Helsinki. Informed consent was obtained in writing prior to any trial-related activities.

|||||||||||||||||||||||||||||||
Recruitment details |
Subjects were screened in the period 07 June 2013 to 30 June 2016. The trial took place at one site in Denmark. | ||||||||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||||||||
Screening details |
Women aged ≥ 18 years, who were first time blood donors and had a p-ferritin concentration < 60 ng/mL were able to participate in the trial after having signed the informed consent form. | ||||||||||||||||||||||||||||||

Blinding implementation details |
Randomisation, preparation, and connection of infusions were handled by personnel otherwise unrelated to the trial. Infusion bags and disposables were non-transparent. In order to ensure that, the infusion bags and all visible disposables will be wrapped in aluminium foil by the personnel unrelated to the trial. All used material will be removed by the same person without revealing the infused fluid.
The monitor performing data monitoring and site management (except IMP handling) was blinded.

Adverse events information
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Timeframe for reporting adverse events |
From the time a subject had signed the informed consent form and until he/she had completed the study, all AEs/SAEs were reported in the CRF.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
An AE was described in the following manner: The nature of the event will be described in precise, standard medical terminology (i.e. not necessarily the exact words used by the subject). If known, a specific diagnosis was stated. Furthermore the Investigator described an AE regarding seriousness, severity, relatedness, and outcome.

20 May 2014 |
• Change of inclusion criterion 3 from ‘P-ferritin < 30 ng/mL’ to ‘P-ferritin < 60 ng/mL’
• Change of inclusion criterion 8 from a specific list of contraceptives required to the more general term ‘adequate contraception (e.g. intrauterine devices, hormonal contraceptives, or double barrier method)’
• Specification that pre-planned procedures and pre-existing conditions that had not worsened were to be recorded on the medical history pages of the CRF
• Change from the current SmPC to the current Investigator’s Brochure for assessing expectedness of AEs
• Specification that it was the responsibility of Pharmacosmos to evaluate the SARs for expectedness
• Specification of the time period for reporting of AEs (from the time a subject had signed the ICF and until she had completed the trial)
• Change of reporting of SAEs (to be reported to Drug Safety, Pharmacosmos, instead of to Max Neeman International)
• The sentence stating that the trial would have a review committee for regular review of safety data was deleted
|
||
05 Aug 2015 |
• The requirement of a maximum of 40 subjects to participate in the exercise test at visit 2 and visit 2a was removed |
