About this study

Official title: A Phase I, Blinded, Placebo-controlled, Dose-escalation Study of the Safety and Pharmacokinetics of XOMA 3AB Administered Intravenously in Healthy Adults

This is a phase I, single-center, placebo-controlled, double-blinded, dose escalation study of anti-botulinum toxin monoclonal antibodies in healthy adult volunteers. Volunteers will be hospitalized in the Johns Hopkins Phase 1 unit during the infusion and until after the 24-hour blood draw. Three escalating dose cohorts of a combination of three anti-botulinum monoclonal antibodies will be evaluated. Each cohort will consist of eight volunteers in which they will receive a single intravenous infusion of active drug or placebo. Placebo will be normal saline. Volunteers will be followed for safety for up to 120 days after infusion depending on dose cohort.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing XOMA 3AB in people with Botulism, run by National Institute of Allergy and Infectious Diseases (NIAID) 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 14 inclusion and 36 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 5 Dec 2014. 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?

Safety and tolerability of XOMA 3AB: occurrence of adverse events and serious adverse events. (time frame: Day 0 to Day 90 and to Day 120 (depending on dose cohort).). 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 NCT01357213, which also lists 1 linked publication.

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 Dec 2014.
