APSV in Vaccinia Naive Adults

August 26, 2010 updated by: National Institute of Allergy and Infectious Diseases (NIAID)

A Multicenter, Double-Blind, Randomized Study of the Safety and Efficacy of Aventis Pasteur's Smallpox Vaccine, USP (APSV) in Vaccinia-Naive Adults.

The study seeks to define, with precision, the safety and efficacy of APSV, two dose potencies of one lot in vaccinia-naive adults. The ability of this vaccine to induce a classic �take� as defined by formation of a lesion at the injection site consistent with the �Jennerian� process (see Appendix A) and vaccine specific immune responses will be assessed. The local cutaneous lesion is considered to be a surrogate for clinical effectiveness of live, replicating smallpox vaccines. Neutralizing antibody formation has been correlated with takes for the Dryvax vaccine and is considered to be cross-protective for other orthopoxviruses, including variola. The study also seeks to characterize preliminarily the cell mediated immune (CMI) response to APSV (as compared to Dryvax).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A Multicenter, double blind, randomized trial in which each volunteer will receive one of 2 dose concentrations of one of two lots of Aventis Pasteur Smallpox Vaccine as a single vaccination (undiluted, 1:5 dilution). Volunteers without a take at day 7 - 9 will be offered a vaccination with Dryvax at the end of the study.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
444

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 32 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

INCLUSION CRITERIA:

  • Adequate renal function defined as a serum creatinine 1.5 mg/dL; urine protein < 100mg/ dL or trace or negative proteinuria (by dipstick), and a calculated creatinine clearance >55 mL/min. Formula for calculations is contained within the Manual of Procedures.

(Note: Renal function is measured to ensure that subjects could meet criteria for use of cidofovir if needed).

  • Age 18-32 (children are excluded due to concerns of safety, including autoinoculation).
  • Willing to sign informed consent.
  • Availability for follow-up for planned duration of the study (56 days following the last vaccination).
  • Acceptable medical history by screen evaluation form and brief assessment.
  • Absence of a typical vaccinia scar and negative history of smallpox vaccination.
  • Negative urine or serum pregnancy test for women of childbearing potential.
  • If the volunteer is female and of childbearing potential, she agrees to use acceptable contraception, and not become pregnant for the duration of the study. (Acceptable contraception includes implants, injectables, combined oral contraceptives, effective intrauterine devices (IUDs), sexual abstinence, or a vasectomized partner).
  • Negative ELISA for HIV or negative Western blot for subjects who have a positive ELISA and have participated in an HIV vaccine trial.
  • Negative hepatitis B surface antigen and negative antibody to hepatitis C virus.
  • Negative urine glucose by dipstick.
  • ALT < 1.5 times institutional upper limit of normal.

EXCLUSION CRITERIA:

  • Allergies to any component of the vaccines (e.g., polymyxin B sulfate, dihydrostreptomycin sulfate, chlorotetracycline hydrochloride).
  • 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 with the exception of squamous cell or basal cell skin cancer.
  • Autoimmune disease.
  • Use of immunosuppressive medication.
  • Corticosteroid nasal sprays are permissible.
  • Medical or psychiatric condition or occupational responsibilities which 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.
  • Smallpox vaccination since 1990 (Vaccinia experience cohorts).
  • Typical vaccinia scar or history of smallpox vaccination (Vaccinia naive cohorts only).
  • Receipt of blood products or immunoglobulin in the past 6 months.
  • Recent donation of the equivalent of a pint of blood within the 30 days prior to enrollment.
  • Acute febrile illness (100.5 F) on the day of vaccination.
  • Pregnant or lactating women.
  • Eczema of 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.

Study Major Dates

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
