About this study

Official title: A Phase I, Single-centre, Open Label Study to Evaluate the Potential Occurrence, Reversibility and Prevention of Bronchoconstriction as Individual Response to Escalating Doses Followed by Repeated Doses of ALX-0171, Administered by Oral Inhalation to Adults With Hyperresponsive Airways

This is a Phase I, single-centre, open label study to evaluate the occurrence and subsequent reversibility and prevention, of bronchoconstriction following single and repeated oral inhalations of ALX-0171 in adults with hyperresponsive airways.

This phase I study is an exploratory study and serves to evaluate the occurrence and reversibility of bronchoconstriction upon inhalation of ALX-0171. The study is an open label trial with a sequential administration regimen of placebo and verum in all planned study subjects. Each subject will start the treatment with a single dose of ALX-0171 placebo (= formulation buffer) followed by escalating doses of ALX-0171 verum.

Eventually a second administration of ALX-0171 placebo may take place at the end of the study (as defined per protocol).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ALX-0171Biological

    Escalating dose of ALX-0171 during maximum 3 consecutive days: from 2.1 mg to maximum 200 mg per inhaled dose followed by daily dose of 70 mg, 140 mg or 200 mg per dose for maximum 4 consecutive days

What is being measured

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

  1. Number of subjects reacting with bronchoconstriction to treatment (ALX- 0171 placebo or ALX-0171 verum) with one or more drops in forced expiratory volume in one second (FEV1) within a period of 8h post-inhalation

    Measured: Within a period of 8 hours post-inhalation

Secondary outcomes (5)
  1. Total number of bronchoconstriction events

    Measured: Day 1 to Day 7

  2. The frequency of use of β2-agonist for the treatment of study drug/procedure induced bronchoconstriction

    Measured: Day 1 to Day 7

  3. Safety markers

    between others: physical examination, vital signs, 12-lead ECG, clinical laboratory (hematology and serum chemistry), urine analysis, serology, adverse events

    Measured: From screening to last follow-up visit which will take place between day 35 and day 42

  4. Pharmacokinetic parameters: plasma concentrations of ALX-0171

    Measured: Day 1 to Day 8

  5. Immunogenicity: presence of anti-drug antibodies (ADA) in serum, presence of ADA in sputum

    Measured: From screening to last follow-up visit which will take place between day 35 and day 42

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALX-0171 in people with Respiratory Syncytial Virus Infection, run by Ablynx, a Sanofi company at 1 site in Germany.

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 12 inclusion and 27 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: finished, as of the sponsor's last update on 13 Jul 2018. 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 Germany. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 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?

Number of subjects reacting with bronchoconstriction to treatment (ALX- 0171 placebo or ALX-0171 verum) with one or more drops in forced expiratory volume in one second (FEV1) within a period of 8h post-inhalation (time frame: Within a period of 8 hours post-inhalation). 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 13 Jul 2018.
