About this study

Official title: Phase I, Single-centre, Open-label Study to Evaluate the Pharmacokinetics of ALX-0171, Administered by Oral Inhalation or Intravenously, in Healthy Male Volunteers

The overall aims of the study are:

  • To provide additional information on the pharmacokinetics of ALX-0171 by measuring (i) local (bronchoalveolar lavage fluid (BALF)) and systemic (plasma) concentrations of ALX-0171 after oral inhalation, and (ii) systemic (plasma) and urine concentrations after intravenous administration.
  • To further determine the safety and local and systemic tolerability of ALX-0171.
  • To further evaluate local (induced sputum) and/or systemic (serum) immunogenicity of ALX-0171, by analysing the potential occurrence of anti-drug antibodies (ADA).

What is being measured

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

  1. Pharmacokinetics: concentration of ALX-0171 after oral inhalation in BALF samples and in plasma samples

    Measured: Day 1 to Day 9

  2. Pharmacokinetics: ALX-0171 concentration in plasma and urine after intravenous administration

    Measured: Day 1 to Day 4

Secondary outcomes (2)
  1. Safety and tolerability: safety markers

    • Lung function test pre- and post-inhalation with 4 mL of ALX-0171 placebo (on Day -1, applicable for oral inhalation only).
    • Lung function tests
    • Physical examination (including physical examination of the lung for oral inhalation)
    • Vital signs
    • 12-lead ECG.
    • Clinical laboratory
    • Limited safety lab (haematology + limited chemistry).
    • Adverse events (AEs) and concomitant medication

    Measured: from signing of Informed Consent Form (ICF) until last follow-up visit (i.e 35 to 42 days after first study drug administration)

  2. Immunogenicity: concentration of Anti-Drug Antibodies (ADA)in induced sputum (after oral inhalation only) and serum

    Measured: during screening until last follow-up visit (i.e. 35 to 42 days after first study drug administration)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALX-0171 in people with Healthy and RSV Infection, run by Ablynx, a Sanofi company at 1 site in Belgium.

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 16 inclusion and 19 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 Belgium. 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?

Pharmacokinetics: concentration of ALX-0171 after oral inhalation in BALF samples and in plasma samples (time frame: Day 1 to 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?
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.
