NCT ID NCT03238079

First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time

Summary

This study tests a new intravenous immunoglobulin (IGIV) called PlasmaCap IG in adults and children aged 2 to 70 with primary immune deficiency diseases (PIDD). Participants receive regular infusions of the therapy for 12 months. The goal is to see if it prevents serious bacterial infections and maintains protective antibody levels, while also checking for safety and tolerability.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Human Immunoglobulin (10% IGIV)

What this could lead to

If successful, this could provide a new, safe option for replacing missing antibodies in people with primary immune deficiency, helping prevent serious infections.

What could go wrong

This is a mid-stage trial with only 63 participants, so results may not apply to everyone. As with any blood product, there is a risk of allergic reactions or transmission of infections.
