Trial summary

This exploratory laboratory only study will assess alterations in immune cells in blood samples that may be responsive to an inflammatory mediator in asthma called IL-33 (Innate lymphoid type 2 cells, basophils and Th2 cells) in response to treatment with ANB020/placebo (a drug that targets IL-33, in the linked… Read more about this study

About this study

This exploratory laboratory only study will assess alterations in immune cells in blood samples that may be responsive to an inflammatory mediator in asthma called IL-33 (Innate lymphoid type 2 cells, basophils and Th2 cells) in response to treatment with ANB020/placebo (a drug that targets IL-33, in the linked clinical trial ANB020-004). The study will involve additional 10ml blood draws on scheduled study visits in the ANB020-004 clinical trial at baseline, 1 week, 5 weeks, 18 weeks (4 visits total). Total number of subjects is 24 at the same 3 participating UK sites as the main linked clinical trial ANB020-004.

Blood samples will be sent on the same day to a flow cytometry laboratory at the NIHR Leicester Biomedical Research Centre (BRC) - Respiratory. A dedicated post doctoral, trained laboratory scientist will analyse the blood samples for the required cell types using a technique called flow cytometry - this technique identifies cell surface and intercellular markers, that together provide a unique cell identity. The experiments will be supervised by a senior research scientist and flow cytometrist Professor Dave Cousins, at the University of Leicester and results of the experiments will be fed back to AnaptysBio (the linked clinical trial Sponsor). Professor Salman Siddiqui at the University of Leicester will oversee the clinical conduct of this laboratory study and act as the Chief Investigator. Professor Siddiqui is also the local site lead Principal Investigator at Leicester for the linked ANB020-004 clinical trial described below.

The linked study (ANB020-004) is a Double-blind Placebo-Controlled Proof of Concept Study to Investigate ANB020 (a drug that targets an inflammatory mediator called IL-33) Activity in Adult Patients with Severe Eosinophilic Asthma. The expected duration of the study is up to 141 days. Screening period of 7-14 days and treatment and follow-up period of 127 days.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To investigate whether treatment with ANB020, a drug that targets IL-33 alters levels of Basophils, Th2 cells or innate lymphoid type 2 cells (ILC2s) in peripheral blood

    To investigate whether treatment with ANB020, a drug that targets IL-33 (an inflammatory mediator in asthma) alters levels of Basophils, Th2 cells or innate lymphoid type 2 cells (ILC2s) in peripheral blood in patients receiving active drug compared to placebo, in a linked clinical trial sponsored by AnaptysBio - ANB020-004.

    Measured: 18 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Asthma, run by University of Leicester at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To investigate whether treatment with ANB020, a drug that targets IL-33 alters levels of Basophils, Th2 cells or innate lymphoid type 2 cells (ILC2s) in peripheral blood (time frame: 18 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Feb 2020.
