Study summary

A multicenter observational study aiming to evaluate the efficacy of kallikrein inhibition by lanadelumab in patients with bradykinin- angioedema

Read the detailed description

The bradykinin-angioedema (AE-BK) is characterized by recurrent and unpredictable episodes of swelling; it can be disabling and disfiguring and the attacks affecting the larynx can be life-threatening.

The clinical symptoms depend on accumulation of bradykinin (BK), a vasoactive peptide responsible for vasodilation and increase of vascular leakage. BK formation depends on activation of the kallikrein-kinin cascade leading to uncontrolled generation of plasma kallikrein and subsequent proteolysis of high molecular-weight kininogen (HK).

Lanadelumab is a fully human monoclonal antibody inhibitor of plasma kallikrein, thereby preventing BK production; it represents an attractive therapeutic strategy for BK-AE prophylaxis.

The aim of this study is to evaluate the kallikrein inhibition by assessing the levels of cleaved HK and the immunogenicity of the lanadelumab.

Study population

Hereditary or Acquired Angiodema

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male/female >18 years old
  • Patient with hereditary or acquired angioedema
  • Patient treated by lanadelumab
  • Patient whose the biological explorations have been carried out or will be carried out at Laboratory of Immunology of CHUGA
  • is obtained from the participant

Exclusion criteria

Exclusion Criteria:

  • Absence of biological material at T0 and M3 (stored for routine analysis)
  • Person under guardianship or curatorship
  • Female who is pregnant, nursing
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Evaluation of the efficacy of the kallikrein inhibition by lanadelumab in patients with bradykinin-angioedema

    Levels of cleaved HK measured by Western Blot

    Time frame: 3 months

Secondary outcomes

  1. Evaluation of the efficacy of kallikrein inhibition by lanadelumab in patients with bradykinin-angioedema between T0 and the others visits

    Levels of cleaved HK as measured by Western Blot Ratio Day 7/ Day 0, Ratio Month 6/ Day 0, Ratio Month 12/ Day (and if possible Month 24/ Day 0) of the levels of cleaved HK as measured by Western Blot - SE2: antidrug antibodies in the sera of patients at Months 3, 6, 12 (and if possible Month 24).

    Time frame: Day 7; 6, 12 and if possible 24 months

  2. Immunogenicity of lanadelumab

    Levels of antidrug antibodies in the sera of patients

    Time frame: Months 3, 6, 12 (and 24 if possible)

  3. Evaluation of therapeutic escape

    Increase/absence of decrease of the number of attacks during lanadelumab administration

    Time frame: Months 3, 6, 12 and if possible 24

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
