Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 32 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Age: 18-32 (Volunteers over 32 years of age are not included since they usually are not vaccinia-naive.) Children are excluded due to concerns of safety, including autoinoculation.
  • Acceptable medical history by screening evaluation form and brief assessment.
  • Negative urine pregnancy test for women.
  • Negative history of smallpox vaccination.
  • Negative ELISA for HIV or negative Western blot for volunteers who have a positive ELISA and have participated in an HIV vaccine trial.
  • Availability for follow-up for planned duration of the study (6 months). Note: Stage 1 - clinic visit at Day 180+/-15 days, Stage 2 - phone call at Day 180 +/- 15 days.

  • If the volunteer is female, she agrees to use acceptable contraception and not become pregnant for the duration of the study.
  • Willing to sign informed consent.
  • Adequate renal functions as defined as a serum creatinine of 1.5 mg/dL, urine protein < 100 mg/dL or negative proteinuria, and a calculated creatinine clearance > 55 mL/min based on the following formulas: For males ((140 minus age in years) x weight in kg)/72 x serum creatinine). For females: 0.85 x ((140 minus age in years) x weight in kg)/72 x serum creatinine). Note: Renal function is measured to ensure subjects could meet criteria for use of cidofovir if needed.

Who cannot join

  • History of immunodeficiency.
  • Serology positive for HIV, hepatitis B, or hepatitis C at the screening visit.
  • Known or suspected impairment of immunologic function including, but not limited to, clinically significant liver disease.
  • Diabetes mellitus.
  • Moderate to severe kidney impairment.
  • Malignancy, other than squamous cell or basal cell skin cancer.
Show all 28Show fewer
  • Autoimmune disease.
  • Use of immunosuppressive medication.
  • Corticosteroid nasal sprays are permissible.
  • Medical or psychiatric condition or occupational responsibilities that preclude subject compliance with the protocol.
  • History of "illegal" injection drug use.
  • Live attenuated vaccines within 60 days of study.
  • Use of experimental agents within 30 days prior to study.
  • Any history of vaccination with any vaccinia vectored or other pox vectored experimental vaccine.
  • Typical vaccinia scar without known history of vaccination.
  • History of smallpox vaccination.
  • Acute febrile illness on the day of vaccination.
  • Pregnant or lactating women.
  • Eczema or any degree or history of eczema.
  • History of exfoliative skin disorders/conditions.
  • Any acute skin disorders of large magnitude, e.g., laceration requiring sutures, burn greater than 2x2 cm.
  • Receipt of blood products or immunoglobulin in the past 6 months.
  • Household contacts/sexual contacts with, or occupational exposure to (other than minimal contact), people with any of the following: pregnancy, < 12 months of age, eczema or history of eczema, previously listed skin disorders/conditions, immunodeficiency disease or use of immunosuppressive medications.
  • Allergies to any component of the vaccines (e.g. polymyxin B sulfate, dihydrostreptomycin sulfate, chlortetracycline hydrochloride, neomycin sulfate).
  • Allergies to any known component of the diluent.
  • Allergies to any known component of VIG, i.e., thimerosal or previous allergic reaction to immunoglobulins.
  • Allergies to cidofovir or probenicid.
  • Blood donation within the past 55 days (stage 1 only).

About this study

Official title: A Phase I/II Study to Evaluate the Safety and Preliminary Efficacy of Various Concentrations of Aventis Pasteur's Smallpox Vaccine, USP (APSV) in Vaccinia-naive Adults

To define the safety of vaccination with APSV as determined by the reactogenicity of the vaccine and the development of expected and un-expected adverse events associated with vaccination.

To assess the proportion of individuals who respond to vaccination with a "take" (those who form a visible lesion at the injection site) 6 to 8 days after the vaccination.

Read the detailed description

The study will be a four-center, randomized, dose finding trial to evaluate safety, preliminary efficacy, and immunogenicity of Aventis Pasteur smallpox vaccine (APSV) in healthy, vaccinia-naive adults. Four concentrations of APSV, derived from 2 lots of vaccine, will be tested; ranging from 10 (exponent 6 pfu per ml) to 10 (exponent 7.5 pfu per ml). Four concentrations of Dryvax (ranging from 10 exp 6 per ml to 10 exp 8 per ml) will be evaluated as a positive control. This study is designed to assess the feasibility of the use of APSV and dilutions of APSV in an emergency vaccination scenario. The study will be conducted in two phases. The initial phase will consist of a single-center, randomized, open-label study in 45 subjects to evaluate the safety and approximate the take rate of undiluted APSV (two lots APSV plus a Dryvax control arm: n=15 per arm). A 14 day post vaccination safety follow-up will be completed for all subjects vaccinated in the initial phase prior to initiation of the second phase of the study with an additional 285 subjects. All subjects will be followed for 56 days post vaccination with a clinic visit at day 180 for stage 1 subjects and a follow-up phone call at day 180 for stage 2 subjects. The expansion phase of the study will be conducted at three additional sites.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Wetvax (APSV) in people with Smallpox, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 sites 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 9 inclusion and 28 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 27 Aug 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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. 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 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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.

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 27 Aug 2010.
