About this study

Official title: A Phase I, Randomized, Double-Blind, Placebo-Controlled Study in Healthy Subjects to Assess the Safety, Tolerability, Pharmacokinetics, and Immunogenicity of CR8020, a Monoclonal Antibody Against Influenza A Viruses, Following Single-Dose and Repeat-Dose Intravenous Administration

The purpose of this study is to assess in healthy subjects the safety, tolerability, pharmacokinetics and immunogenicity of single escalating doses of CR8020, a monoclonal antibody against influenza A viruses.

Read the detailed description

This randomized, double-blind, placebo-controlled dose escalation study will enroll up to 5 cohorts of healthy subjects. Eight subjects will be enrolled in each cohort and will receive a single 2-hour intravenous infusion of CR8020 (6 subjects) or placebo (2 subjects) on Day 1. Subjects will be dosed in pairs of two. Once all subjects in a cohort have completed Study Day 8, the preliminary safety data will be reviewed. Provided that no safety issues are identified, dose escalation to the subsequent cohort may be permitted. After the completion of Cohort 5 enrollment, and the preliminary safety and tolerability of the 50mg/kg dose is demonstrated, a sixth cohort will be enrolled. Cohort 6 will be comprised of 24 subjects (randomized 5:1 to CR8020 30 mg/kg or placebo) who will receive 2-hour intravenous infusions on Days 1 and 8.

What is being measured

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

  1. Adverse events and changes in laboratory parameters and vital signs as measures of safety and tolerability of single escalating doses of CR8020

    Measured: From baseline to 98 days post-dose

Secondary outcomes (2)
  1. Assessment of pharmacokinetics of single escalating doses of CR8020

    Pharmacokinetic parameters include area under the serum concentration-time curve from zero to the time of the last measurable concentration (AUC0-t), area under the serum concentration-time curve from zero to infinity (AUC0-inf), maximum concentration (Cmax), time of Cmax (tmax), systemic clearance (CL), terminal elimination half life (t1/2), etc.

    Measured: From baseline to 98 days post-dose

  2. Assessment of antibodies binding to CR8020 as a measure of immunogenicity of single escalating doses of CR8020

    Measured: From baseline to 98 days post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 2 mg/kg CR8020, 5 mg/kg CR8020 and 15 mg/kg CR8020 in people with Influenza, run by Crucell Holland BV at 1 site in United States.

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 17 inclusion and 44 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 19 Dec 2013. 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 States. 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 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?

Adverse events and changes in laboratory parameters and vital signs as measures of safety and tolerability of single escalating doses of CR8020 (time frame: From baseline to 98 days post-dose). 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 19 Dec 2013.
