Plain English Summary

Background and study aims
Administration of antibodies into a vein (intravenous immunoglobulin [IVIG]) has proved to be useful in a variety of clinical conditions. In patients suffering from immune thrombocytopenia (ITP), several studies have shown IVIG to be effective in increasing platelet counts (PC) to prevent or control bleeding. In this study we will assess whether Octagam 10% similarly corrects (i.e., increases) the platelet count compared with normal IVIG.

Who can participate?
Patients aged 18 – 65 with chronic Primary Immune Thrombocytopenia (ITP) of at least 12 months duration.

What does the study involve?
All patients will receive two infusions of Octagam 10% for two consecutive days. Vital signs will be monitored at the start of the infusion, at least once during the infusion and about 1 hour after the end of the infusion. Over the study period of 22 days participants will be asked to give a small amount of blood for assessment of platelet count and safety parameters.

What are the possible benefits and risks of participating?
Patients will receive highly purified antibodies for a quick increase in platelet count. Due to the 10% concentration, this may shorten the infusion time compared to commercial IVIG treatments the patient previously received. The product underwent two times some of the production steps in which impurities and viruses are eliminated. During this study the patients’ health condition will be assessed very thoroughly and in shorter intervals than normal. Even though the patient may not receive any personal benefit, participation in this study will benefit society as a whole by providing new information about the treatment of ITP and thus improving quality of life to those who suffer the condition. The risks of IVIG administration are well documented. In general, the incidence of adverse events associated with IVIG tends to increase with the rate of infusion, and thus the recommended dosage, infusion rates, and monitoring procedures should be adhered to.

Where is the study run from?
The study has been set up by a pharmaceutical company producing and selling products developed from blood plasma, called Octapharma AG (Switzerland).

When is the study starting and how long is it expected to run for?
It is anticipated that recruitment will start in August 2012. Participants will be enrolled in the study for a period of almost 2 years or until the 30th patient has completed the study. The study is expected to be completed in March 2014.

Who is funding the study?
Funding has been provided by Octapharma AG (Switzerland).

Study information

Scientific title

Prospective, open-label, non-controlled, multicenter, phase III clinical study to evaluate the efficacy and safety of Octagam 10% in Primary Immune Thrombocytopenia


Study hypothesis

The efficacy of Octagam 10% ('double-processed' Octagam) in correcting the platelet count (PC) is to be expected for a compound of this class.

On 10/04/2013 the following changes were made to the trial record:
1. The anticipated start date was updated from 11/07/2012 to 30/08/2012.
2. The anticipated end date was updated from 30/06/2014 to 29/03/2013.
