NCT01502345

Brief Summary

The purpose of this study is:

  • To assess safety and tolerability of the HTNV and PUUV DNA vaccines, pWRG/HTN-M(x) and pWRG/PUUV-M(s2), administered intramuscularly using a TDS-IM electroporation device Secondary:
  • To evaluate clinical immunogenicity of the HTNV and PUUV DNA vaccines, pWRG/HTN-M(x) and pWRG/PUUV-M(s2), including an assessment of the acute procedure tolerability when administered with the TDS-IM electroporation.

Eligibility Criteria

Age18 Years - 49 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Healthy adult male or non-pregnant, non-lactating female, ages 18-49 (inclusive) at time of screening
  • Have demonstrated adequate comprehension of the protocol, by achieving a score of at least 80% correct on a short multiple-choice quiz
  • Individuals who fail to achieve a passing score on the initial quiz will be given the opportunity to retest after a review of protocol information
  • Individuals who fail the comprehension assessment for the second time will not be enrolled
  • Have provided written informed consent before screening
  • Free of clinically significant health problems, as determined by pertinent medical history and clinical examination before entry into the study
  • Available and able to participate for all study visits and procedures
  • If sexually active, known to be at least 1 year post-menopausal, or willing to use an effective method of contraception (e.g., birth control pill, diaphragm, cervical cap, intrauterine device, condom, or anatomical sterility \[in self or partner\]) from the date of screening until at least 6 months after the last vaccination
  • Negative hantavirus IgG antibody test result at screening (ELISA)

You may not qualify if:

  • History or serologic evidence of prior infection with either HTNV or PUUV virus, or prior participation in a HTNV or PUUV virus vaccine trial
  • History of severe local or systemic reactions to any vaccination or a history of severe allergic reactions
  • Any serologic evidence of hepatitis B or C infection
  • Ongoing participation in another clinical trial
  • Receipt or planned receipt of any vaccination, experimental or otherwise, within the period 30 days prior to initial injection through 60 days after the Day 70 follow-up (approximately a 6 month period in total)
  • Individuals in whom a skinfold measurement of the cutaneous and subcutaneous tissue for all eligible injection sites (deltoid region) exceeds 40 mm
  • Individuals in whom the ability to observe possible local reactions at the eligible injection sites (deltoid region) is, in the opinion of the investigator, unacceptably obscured due to a physical condition or permanent body art
  • Acute or chronic, clinically significant hematologic, pulmonary, cardiovascular, hepatic or renal functional abnormality as determined by the investigator based on medical history, physical examination, EKG, and/or laboratory screening test
  • Pregnant or lactating female, or female who intends to become pregnant during the study period
  • Administration of immunoglobulins and/or any blood products within the 120 days preceding study entry or planned administration during the study period
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus infection
  • Administration of chronic (defined as more than 14 days) immunosuppressants or other immune-modifying drugs within 6 months of study entry
  • For corticosteroids, this will mean prednisone, or equivalent, greater than or equal to 0.5 mg/kg/day
  • Inhaled and topical steroids are allowed
  • Any chronic or active neurologic disorder, including seizures and epilepsy, excluding a single febrile seizure as a child
  • +5 more criteria
