General information about the trial
|
|||
Main objective of the trial |
The primary objective of this study is to determine the efficacy of subcutaneous immunoglobulin octanorm in the maintenance treatment of DM patients who have previously responded to IGIV therapy.
|
||
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 occurrence of AEs, local injection site reactions, safety labs, vital signs and physical examinations.

octanorm or placebo | ||||||||||
Arm description |
Subjects were to be randomly assigned to either 0.5 g/kg/week octanorm or to placebo. A dose of 0.5 g/kg/week had to be administered subcutaneously every week (±2 days). A minimum interval of 4 days must have been kept in between two consecutive subcutaneous infusion cycles. | ||||||||||

Dosage and administration details |
The only patient treated in the study was assigned to octanorm. Octanorm had to be administered subcutaneously every week (±2 days) using a syringe driver for precise infusion rates. The total dose/volume of a weekly infusion was calculated on the basis of the body weight (0.5 g/kg). The weekly infusion was performed in two separate sessions (= 1 infusion cycle for a given weekly administration). An infusion cycle comprises both sessions to be administered on 1 or 2 days, either on the same day or on two consecutive days or with maximum one day in between two sessions.

End point title |
Clinically important deterioration [1] | ||||||||
End point description |
Primary endpoint is defined as the proportion of patients with clinically important deterioration during the treatment period up to Week 32. A patient with clinically important deterioration is defined as a patient with 1) MMT 8 worsening ≥ 6 points (scale of 150) OR CDASI worsening ≥ 5 points, AND 2) a Physician’s Global Disease Activity VAS worsening ≥ 2 cm.
