General information about the trial
|
|||
Main objective of the trial |
To assess the efficacy of immunoglobulin administered together with hyaluronidase (HyQvia) in large doses subcutaneously compared to conventional treatment with subcutaneous immunoglobulin (Subcuvia) in patients with MMN
|
||
Protection of trial subjects |
This study was conducted in accordance with the recommendations of the International Conference on Harmonization (ICH) Guideline for Good Clinical Practice and was monitored by the the local GCP units throughout the study.

Recruitment
|
||||||||||||||||
Recruitment details |
Recruitment was conducted at all three departments in Denmark responsible for the treatment of multifocal motor neuropathy, the Department of Neurology, Aarhus University Hospital, the Department of Neurology, Odense University Hospital and Department of Neurology, Rigshospitalet, Copenhagen University Hospital. | |||||||||||||||

Notes [1] - The number of roles blinded appears inconsistent with a single blinded trial. It is expected that there will be one role blinded in a single blind trial. Justification: The same blinded person assessed the patients during study and upon study completion was unblinded and analyzed data.

Justification: The same blinded person assessed the patients during study and upon study completion was unblinded and analyzed data. |

Recombinant human hyaluronidase was manually injected at a dose of 80 U/g IgG followed by infusion of a 10% solution of human normal immunoglobulin (HyQvia, Shire, Lexington, MA, USA) [3] using an
electronic peristaltic pump (Mini Rythmic PN+ R, Micrel Medical Devices, Athens, Greece). The maximum volume infused at one site was 600 ml at a rate of 300 ml/h.
