About this study
Official title: A Phase I, Double-blind, Randomized, Placebo Controlled, Dose Escalation Study of Valortim® (MDX-1303) Administered Intravenously (IV) as a 120 Minute Infusion in Healthy, Normal Subjects
Valortim is the name of the experimental drug that volunteers will receive in this study. Valortim may also be called MDX-1303. Experimental means that the drug is not yet approved by the Food and Drug Administration (FDA). Valortim is a monoclonal antibody (laboratory-made immune system molecule) for the treatment of inhalation anthrax (when the infection starts in the lungs). Valortim works by attaching itself to part of the anthrax toxin preventing the toxin from doing damage to cells. This study is being conducted to see if Valortim given over 120 minutes is safe and tolerable. This study will take place in five parts: Screening Phase, Check-in Phase (the day you arrive at Quintiles to start the study), Treatment Phase (the time when you receive the study medication), Follow-up Phase (the time after you receive the study medication) and Final Visit.
Read the detailed description
Twenty-eight subjects will be recruited and entered into one of three dose groups 1mg/kg, 5mg/kg, 10mg/kg or placebo. Subjects will be stagger dosed into one of the three groups and randomly assigned to receive Valortim or saline. Subjects will reside in the clinical trial Phase I Unit from Day -1 through Day 2. After discharge on Day 2, all subjects will return to the Phase I unit 7 times at specified time points over an additional 130 days post-dosing (133 days total participation from check-in on Day -1)or placebo.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Normal Saline for Injection and MDX1303 in people with Anthrax, run by PharmAthene, Inc. 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 1 inclusion and 1 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 9 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?
Safety (time frame: 133 days). 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 9 Dec 2013.
