Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - NewGam

Experimental: 0.5 g/kg NewGam - All patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (0.5g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days).

Experimental: 1.0 g/kg NewGam - All patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (1.0g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days).

Experimental: 2.0 g/kg NewGam - All patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (2.0g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days).


Treatment: Drugs: NewGam
In the Dose-evaluation Phase, all patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (0.5, 1.0 or 2.0 g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days). If a patient is randomized to receive the low or medium NewGam dose, the same volume with the same infusion rate as would have been applied in case the patient would have been randomized to 2.0 g/kg NewGam will be used, thus supplemented with an authorized 0.9% w/v isotonic sodium chloride solution as appropriate and detailed in the following infusion bag split to maintain the blinding
