Condition(s) targeted: Secondary Recurrent Miscarriage

Intervention: Intravenous immunoglobulin (Drug); Human albumin (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Rigshospitalet, Denmark

Official(s) and/or principal investigator(s):
Ole B. Christiansen, MD, D.M.Sc., Principal Investigator, Affiliation: Rigshospitalet, Denmark


The investigators want to test whether infusions of intravenous immunoglobulin - a blood

product known to modify immune responses - in early pregnancy will increase the chance of a

subsequent live birth in women with three or more miscarriages after a birth and a total of at least four miscarriages. This will be done in a trial where 82 patients will be randomly allocated to infusions with intravenous immunoglobulin or placebo during pregnancy.

Clinical Details

Official title: A Randomized, Placebo-controlled, Double-blind Trial of Intravenous Immunoglobulin for Women With Unexplained Secondary Recurrent Miscarriage

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: The difference in the subsequent livebirth rate among patients with secondary recurrent miscarriage who, during the trial, receive intravenous immunoglobulin or placebo, respectively, without any exclusions (ITT analysis)

Secondary outcome: The difference in the subsequent livebirth rate among women with secondary recurrent miscarriage who receive intravenous immunoglobulin or placebo, respectively, after relevant and predefined exclusions (PP analysis).


Minimum age: 18 Years. Maximum age: 40 Years. Gender(s): Female.


Inclusion Criteria:

- 4 or more miscarriages before the end of gestational week 14 in patients with

- Allergy to albumin, IvIg or one of the substances added to preserve the drugs.

- Presence of chronic disease, which necessitate permanent treatment with e. g.
