Safety, Tolerability & Immunogenicity of the Recombinant Plague Vaccine rF1V

United States40 participantsStarted 2004-11

Plain-language summary

The purpose of this study is to evaluate the safety and tolerability of a two-dose schedule of the recombinant plague vaccine rF1V in healthy volunteers when given as an intramuscular (IM) injection at four ascending dose-levels. The purpose of the Cohort 4 Extension is to evaluate the safety and tolerability of a third intramuscular (IM) dose of 160 ug rF1V in healthy volunteers who have previously been vaccinated with the same concentration of rF1V vaccine.

Inclusion Criteria: * The volunteer is male or female and 18 to 40 years of age (inclusive) at the time of the first dose of investigational product * Good health as determined by screening medical history and physical examination * The volunteer has the following laboratory parameters within normal range: total WBC, Hemoglobin, platelets, LFT (AST, ALT, ALP, Bilirubin) and/or ≤ 1+ proteinuria. Other laboratory parameters must be within 10 % of the upper or lower limits of the normal range of the University of Kentucky clinical laboratory and not clinically significant as assessed by the Investigator and/or Sponsor Medical Monitor. * The volunteer has a normal electrocardiogram (ECG). However, if a potential volunteer is reported to have a benign ECG abnormality (e.g., sinus bradycardia) the results may be discussed with the Sponsor Medical Monitor and Covalent Medical Monitor. With the agreement of the Investigator, Covalent Medical Monitor and Sponsor Medical Monitor and documentation of the consultation in the volunteer's study record the Investigator may include the volunteer in the study. * The volunteer is willing to have his or her blood samples stored for future plague research studies. * The volunteer has signed the Informed Consent Form, successfully completed (at least 90 % correct) the Test of Understanding, and has signed the HIPAA authorization form. * The volunteer agrees not to donate blood for at least 30 days following vaccination. * The volunteer is willin…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
