About this study
Official title: An Open-Label Study to Evaluate the Immunogenicity and Safety of Raxibacumab (Human Monoclonal Antibody to B. Anthracis Protective Antigen) Administered in Healthy Subjects
This is an open-label study to evaluate the immunogenicity and safety of raxibacumab in healthy adult male and female subjects. Subjects who have received raxibacumab >= 4 months ago will be enrolled and dosed as follows: A maximum of 25 subjects (to include 3 evaluable female subjects) will receive a second dose of raxibacumab equal to that of the previous dose >= 4 months following the first dose. Subjects will remain in house from Day 0 until Day 1 and will be followed for 70 days after receiving the second dose of raxibacumab. Raxibacumab has been shown to provide improved survival in rabbit and monkey anthrax spore challenge studies. Preliminary data from our rabbit pivotal efficacy study showed significant survival benefit for raxibacumab over placebo. Exposure to anthrax and resulting clinical disease can occur more than once, especially in individuals who do not develop protective immunity. Hence, if clinically indicated for the treatment of anthrax, there may be a requirement for the repeat administration of raxibacumab. The rationale of the study is to evaluate the immunogenicity and safety of repeat administration of raxibacumab with a >= 4 month interval between dosing.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Who Developed a Positive Anti-raxibacumab Antibody Response
Number of participants who developed an positive anti-raxibacumab antibody response during the study were assessed.The antibody response to raxibacumab was assessed using a screening assay (i.e. by electrochemiluminescence counts). Positive samples would be further tested in an inhibition of binding assay to confirm the specificity of binding.
Measured: From the date of the dose administration of study agent for this study (Day 0) until Day 70
Secondary outcomes (12)
Number of Participants With Any Adverse Event (AE) or Any Serious Adverse Event (SAE) During the Treatment Period
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect. Medical or scientific judgment should be exercised in deciding whether reporting is appropriate in other situations. Refer to the General Adverse AE/SAE module for a complete list of AEs and SAEs.

This is an open-label study to evaluate the immunogenicity and safety of raxibacumab in healthy adult male and female subjects. Subjects who have received raxibacumab >= 4 months ago will be enrolled and dosed as follows: A maximum of 25 subjects (to include 3 evaluable female subjects) will receive a second dose of raxibacumab equal to that of the previous dose >= 4 months following the first dose. Subjects will remain in house from Day 0 until Day 1 and will be followed for 70 days after receiving the second dose of raxibacumab.

Hence, if clinically indicated for the treatment of anthrax, there may be a requirement for the repeat administration of raxibacumab.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Raxibacumab in people with Therapeutic Treatment of Inhalation Anthrax, run by Human Genome Sciences Inc..
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 7 inclusion and 8 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 29 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.
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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 25 Jun 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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 Participants Who Developed a Positive Anti-raxibacumab Antibody Response (time frame: From the date of the dose administration of study agent for this study (Day 0) until Day 70). 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 29 Nov 2018.
