What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
TAK-771 (immune globulin with hyaluronidase)
What this could lead to
If successful, this could confirm that TAK-771 is safe for long-term use in managing primary immunodeficiency diseases.
What could go wrong
This is a small, open-label extension study with only 15 participants, so results may not apply to all patients. Side effects are still possible.
