Eligibility Criteria

18 Years - 60 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

General:

  • Age: 18 to 60
  • Complete a written assessment of understanding prior to enrollment and verbalize understanding of all questions answered incorrectly
  • 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:

    1. An active condition that is life threatening
    2. A condition for which repeated injections or blood draws may pose additional risk to the participant
    3. A condition that requires active medical intervention or monitoring to avert grave danger to the participant's health or well-being
    4. 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.
  • Negative for Hepatitis B surface antigen and Hepatitis C virus (HCV) antibodies (If HCV antibodies are positive, and negative for HCV by polymerase chain reaction (PCR), subject is eligible)
  • Negative Food and Drug Administration (FDA)-approved human immunodeficiency virus (HIV) blood test within 8 weeks prior to enrollment
  • Normal urine dipstick or urinalysis:

    1. Negative glucose, and
    2. Negative or trace protein and negative or trace hemoglobin (if trace hemoglobin is present, a urinalysis is required to exclude participants with counts greater than the institutional normal range)

5. Study Description

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.
Detailed Description
In the event of a smallpox outbreak, or threat of one, mass immunization of all vulnerable individuals would take place. This would include persons with immunodeficiency as seen post Hematopoietic Stem Cell Transplant (HSCT). The current Food and Drug Administration (FDA) approved smallpox vaccine (Dryvax®) is a live replicating virus (vaccinia) and is contraindicated in both immunocompromised persons and those in close physical contact with them. The Modified Vaccinia Ankara (MVA), specifically IMVAMUNE® has been developed as a safer, less reactogenic vaccine against smallpox. Study participants will include 24 male or female participants, from 18 to 60 years of age. This study assesses the safety, reactogenicity and immunogenicity of 2 doses of MVA-BN (IMVAMUNE®) given to persons who have undergone an HSCT more than 2 years prior to study participation. There are 2 arms in the study, each receiving 2 doses 28 days apart of either 1 x 10^7 or 1 x 10^8 tissue culture infectious dose 50 (TCID50). Each arm will be comprised of 12 subjects, 10 of whom will receive IMVAMUNE® and 2 of whom will receive placebo under a double blind, randomized allocation. Subjects will be followed for safety and reactogenicity. Clinical assessments will be performed and blood samples will be obtained sequentially for safety and immunogenicity determinations. All subjects will complete a memory aid for 15 days after each vaccination to record oral temperature and note the occurrence of solicited and unsolicited adverse events as well as any medication use. Adverse events will be collected for 56 days after each vaccination. Serious adverse events and concomitant medications will be collected throughout the entire study period. Study staff will assess subjects clinically at days 14 and 28 after each vaccination and on days 42, 56, 84, and 180. Hematology and blood chemistry studies including hemoglobin, white blood cell and platelet counts and kidney and liver function tests will be obtained. Electrocardiogram and Troponin I or T will be obtained prior to first vaccination and on days 14 and 28 after each immunization and at day 180. Clinical laboratory assays will be conducted in the clinical laboratory at both the Brigham and Women's Hospital or the Dana Farber Cancer Institute. The primary objective of this study is to determine the safety and reactogenicity of MVA in persons who have undergone allogeneic HSCT more than 2 years prior to study participation. The secondary objective of this study is to determine the immunogenicity of MVA in persons who have undergone HSCT more than 2 years prior to study participation. Immunogenicity will be determined by humoral immune responses and cell mediated immune responses.
