NCT00565929

Brief Summary

The purpose of this study is to compare how the body's immune system reacts to a vaccine against smallpox infection, called Modified Vaccinia Ankara (MVA) and to evaluate the safety of this vaccine. Study participants will include 24 adults, ages 18-60 years, who have undergone a stem cell transplant more than 2 years ago. Study procedures will include a physical exam, blood samples, heart activity assessments, and urine samples. Participants will be assigned to 1 of 2 possible study vaccine groups. The participants will receive 1 of 2 possible vaccine doses or placebo (substance containing no medication) 28 days apart. Participants will make at least 8 visits to the clinic during the course of the study; additional visits may be needed if the participant experiences side effects from the vaccine. Participants may be involved in study related procedures for about 6 months.

MVA-BNBIOLOGICAL

The smallpox vaccine is a liquid frozen solution formulated to contain 0.605 mg Tris and 4.090 mg sodium chloride (NaCl) per 0.5 mL dose. The concentration of the virus will be 1 X 10\^8 tissue culture infectious dose 50 (TCID 50) per 0.5 mL dose and may be diluted in a solution of 0.9% saline prior to vaccination. Smallpox vaccine administered in 2 doses approximately 28 days apart in one of the following doses: 1X10\^7 or 1X10\^8 TCID 50.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • General:
  • Age: 18 to 60

  • Informed consent: Be able, willing, and have signed the informed consent form
  • Undergone stem cell transplant more than 2 years prior to enrollment
  • Current Health: Be in good general health without evidence of active malignancy and off immunosuppressant medications. Without evidence of clinically significant medical history, physical examination findings, or clinically significant abnormal laboratory results. A clinically significant condition or process includes one or more of the following:
  • An active condition that is life threatening
  • A condition for which repeated injections or blood draws may pose additional risk to the participant
  • A condition that requires active medical intervention or monitoring to avert grave danger to the participant's health or well-being
  • A condition or process in which signs or symptoms could be confused with reactions to vaccine
  • Laboratory:
  • Hematology and chemistries: Chemistries within 1.25x of the institutional normal limits for age and sex for alanine aminotransferase (ALT), aspartate aminotransferase (AST), Alkaline Phos, and Total Bilirubin. Creatinine less than or equal to 1.8 mg/dL. Platelets and Troponin I or T must be within normal range. Hemoglobin above 10.5 gm/dL for women and 11.5 gm/dL for men and white blood cells (WBC) between 3,000 and 12,500 cells/mm\^3.
