Filter by:The purpose of the study is to assess the pharmacokinetics of three doses of NP-015 (210, 420 or 840 units TNA) in healthy volunteers. To evaluate the safety of NP-015 based on adverse events and laboratory assessments. To determine the dose proportionality relation of three different doses of NP-015.
This is a dose ranging study comparing different vaccine schedules of rPA vaccine, for Anthrax, to the licensed dose of AVA, another Anthrax vaccine. Safety and the capability to induce an immune response will be evaluated.

The purpose of this study is to evaluate the safety and pharmacokinetics (how long a drug stays in the bloodstream and how high the levels of the drug are at different times) of ETI-204 following intravenous (IV-into a vein) injections, and to evaluate the effects that ETI-204 may have on the pharmacokinetics of oral (by mouth) ciprofloxacin, an antibiotic approved by the U.S. Food and Drug Administration (FDA). ETI-204 is an experimental drug (not approved by the FDA) intended to protect against anthrax (a bacterial infection). Approximately 36 male and female healthy volunteers ages 18 to 50 will be in this study. Participation in this study may last up to eight weeks. Volunteers will have a single IV dose of the ETI-204 study drug or placebo (inactive substance, and some participants will also receive ciprofloxacin. They will stay in the Clinical Pharmacology Unit at least 36 hours after the dose.
Our 4-year project uses public domain software and content developed by a University of Alabama at Birmingham (UAB) team and updates, refines, and tailors it to the unique clinician populations and electronic educational applications of VAMCs We are testing an innovative, web-based intervention adapted specifically for the VA to increase syndromic recognition, treatment, and post-exposure prophylaxis of biological warfare agents at multiple VA sites via a randomized controlled trial (RCT). Ultimately, we will disseminate the intervention throughout the entire VA system.
Anthrax Clinical Trial Objectives: To assess whether: - Anthrax vaccine (AVA or BioThrax, BioPort Corp. Lansing MI) administered by the intramuscular (IM) route elicits antibody responses that are not inferior (i.e., "non-inferior") to that achieved by the currently licensed schedule. - BioThrax administered by the IM route and containing fewer numbers of doses elicits antibody responses that are not inferior (i.e., "non-inferior") to that achieved by the currently licensed schedule. - Differences in reactogenicity exist between the IM and subcutaneous (SQ) administration of BioThrax. Additionally for the final report we will assess whether: - Occurrence of adverse events following AVA administration is influenced by selected risk factors.
This study will examine the recombinant, that is, produced by genetic engineering, protective antigen (rPA) that brings about antibodies to neutralize the anthrax toxin and that could therefore be predicted to offer protection against anthrax. Today, anthrax is rarely encountered in the United States, since the introduction of vaccines for cattle in the 1930s. A human vaccine was licensed in 1970. Vaccination against anthrax has been confined to people at risk, such as wool sorters and some veterinarians. However, the rising prospects of B. anthracis being used as a weapon have led to routine administration of the anthrax vaccine to members of the armed forces. Adults who are in good health may be eligible for this study. The involvement of 300 adults is planned. Participants will have a general physical exam and test for vital signs. There will also be collection of blood for chemistry and hematology; urinalysis; tests for HIV, hepatitis B and C, and liver function; and a pregnancy test, if applicable. On a random basis, patients will receive one of the rPA formulations. Two doses of rPA will be evaluated, 10 microgram ((Micro)g) and 20 (Micro)g. This evaluation aims to establish the safety and most desirable level of dosage. Patients will receive one injection of the vaccine, administered in the left shoulder or left thigh. About 30 minutes later, their temperature will be taken, and the injection site will be inspected. Rare but severe reactions could occur if there is extreme sensitivity to a vaccine. However, such an occurrence is extremely rare following a vaccine, and if there are any dangerous symptoms, they can be effectively treated by medications available to patients while they are at the clinic. If there are no significant abnormal results, patients may return home. About 6 hours later and daily for 7 days, they will take their temperature and examine the injection site. The vaccine may cause temporary discomfort at the site of injection, and participants may experience a mild fever for 1 or 2 days after vaccination. Patients will receive diary cards, a digital thermometer, and instructions on taking their temperature and measuring redness and swelling at the injection site, as well as for recording aches, muscle pain, or sensitivity to light for 7 days. They will be examined at the clinic at 72 hours following vaccination and also on the 7th day if they have a fever at or above 100.4 , if swelling is at or more than 2 inches, or if they request an exam. Meanwhile, a clinic staff member will call patients and discuss the findings. Then patients will receive a second and third injection of the same vaccine at 2-month intervals. There will also be interviews about patients' health at each visit to the clinic, plus monitoring of the vaccination after 6 hours and for 7 days. One year later, patients will receive a fourth injection of the same vaccine. Direct benefit to participants in this study is not guaranteed, although an antibody response is predicted. The results in this study will help in the development of improved vaccines for anthrax.
The purpose of this phase 1 study is to evaluate the safety and immunogenicity of rPA102 vaccine, using anthrax vaccine adsorbed (AVA) as a comparator.
The purpose of this study is to assess the safety and immunogenicity of rPA102 vaccine given intramuscularly at 0 and 4 weeks over 2 dose ranges and 4 adjuvant levels.
The primary objective is to determine the tolerability and safety, from days 0 to 210, of escalating doses of rPA either with or without Alhydrogel (an adjuvant; used to increase the action of the principle drug) given in a two-dose, intramuscular regimen to health adults. The secondary objective is to evaluate antibody responses to rPA, from days 0 to 210, following one of four escalating doses of vaccine given with and without Alhydrogel given in a two-dose series to healthy adults, and to compare immune responses following rPA with those following BioThrax (tm) given by either the intramuscular or SQ route. The tertiary objective is to describe the antibody kinetics following vaccination. This information will be used to determine the most probable optimal dose of rPA and/or Alhydrogel that is safe, well tolerated, and maximally immunogenic for use in future phase II trials.
