Show all 25Show fewer
  • Individuals who are determined as healthy by the Investigator, based on medical evaluations including, but not limited to, medical history, physical examination, laboratory tests, vital signs, and electrocardiogram (ECG).
  • Subjects have mild, stable, allergic asthma with episodic wheeze and shortness of breath. Asthma therapy is limited to inhaled, short-acting β2 agonists (should not be used on more than 2 occasions in a week, excluding for prophylactic treatment).
  • Subjects have no current exposure to allergens to which the subject experiences asthmatic responses (except for the house dust mite).
  • Positive methacholine challenge (PC20 ≤16 mg/mL) at screening (Visit 2).
  • Positive skin-prick test to at least one common aeroallergen at screening (Visit 1).
  • Positive early and late airway responses during the screening allergen challenge. The EAR will be a fall in FEV1 of ≥20% during the 2 hours after allergen challenge. The LAR will be defined as a fall in FEV1 of ≥15% during the 3-7 hours after allergen challenge.
  • Pre-bronchodilator FEV1 at screening (Visit 1) ≥70% of predicted normal value.
  • Weight
  • Body mass index (BMI) within the range 18 to 35 kg/m2 (inclusive).

  • WOCBP should be stable on their chosen method of highly effective birth control for a minimum of 3 months prior to Visit 1, and willing to use this for the entire duration of the study (from the time they sign the ICF), and for 1 month after the last dose of study treatment. With the exception of abstinence, addition of a barrier method (such as a condom) must be used from Visit 1 until 1 month after the last dose of study treatment. Female subjects must not donate ova for the same time period
  • Male subjects must be surgically sterile or using an acceptable method of contraception for the duration of the study (from the time they sign consent) and for 1 month after the last dose of study treatment to prevent pregnancy in a partner (unless the partner is considered postmenopausal).

  • Negative urine pregnancy test for female subjects, confirmed pre dose prior to randomization.
  • Visit 6 pre dose methacholine PC20 ≤1 doubling concentration lower than the corresponding baseline value at Visit 2.
  • Ability to produce a sputum sample and viable cytospin for assessment of the cell differential count at the screening allergen challenge. The purpose of this analysis is to support exploratory endpoints only and is not related to treatment decisions.
  • A Visit 6 pre-dose FEV1 that is not more than 10% lower than that measured at the screening Visit 2, to demonstrate asthma stability.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AZD8154 nebulizer suspension, 20 mg/mL in people with Asthma, run by AstraZeneca at 5 sites in Canada.

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

Who may be eligible to take part?

The sponsor lists 25 inclusion and 41 exclusion criteria. 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: withdrawn, as of the sponsor's last update on 3 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Canada. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Maximal percentage decrease in forced expiratory volume in 1 second (FEV1) 3-7 hours post-allergen challenge (time frame: At day 9). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04187508.

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 3 Nov 2020.
