NCT ID NCT05397431
First seen Jun 24, 2026 · Last updated Aug 05, 2026 · Updated 3 times
Summary
This study follows 155 people in Japan with hereditary angioedema (HAE) who are taking TAKHZYRO (lanadelumab) injections every two weeks. Researchers will monitor side effects and check if the drug helps control swelling attacks over 12 months. The goal is to see how well TAKHZYRO works in everyday medical practice.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lanadelumab (TAKHZYRO)
- What this could lead to
- If successful, this study could confirm that TAKHZYRO is safe and effective for long-term use in controlling HAE attacks.
- What could go wrong
- This is an observational survey, not a controlled trial, so results may be less definitive. Side effects are still possible, and the study only includes Japanese participants, so findings may not apply to everyone.
