Not yet recruiting

• Conditions: Primary Immunodeficiency Diseases (PID)
• Interventions: Drug: IVIG-VImmune; Drug: IVIG-Immuglo

• Registration Number: NCT07017036
• Lead Sponsor: Virchow Group

Brief Summary

The study duration for individual patients will be up to 55 weeks for the 4-weekly and 3- weekly schedule of the treatment which includes 3 weeks for screening, 48 weeks for Study Medication administration and 4 weeks for follow-up assessments

Detailed Description

Eligible subjects will receive either test or reference as per the randomization in 1:1 ratio.

Test group: V-Immune will be administered at 200-800 mg/kg dose as a single infusion every 3 or 4 weeks. Patients will be treated with V-Immune from Week 0 (first dose) till Week 48 at an investigator-recommended dose.

Reference group: Immuglo will be administered at 200-800 mg/kg dose as a single infusion every 3 or 4 weeks. Patients will be treated with V-Immune from Week 0 (first dose) till Week 48 at an investigator-recommended dose

5. Patients must be able to adhere to the study visit schedule and other protocol requirements.

6. If subject is a female and is

   a. -of child bearing potential, she should be practicing an acceptable method of birth control for the duration of tl1e study as suggested by the investigator, such as a combination of male condom with either cap, diaphragm or sponge with spermicide (double barrier method), intrauterine device (IUD), or abstinence OR surgically sterile, bilateral tubal ligation done at least 6 months before the study should be documented
