Effect of Antimalarial Drugs to Rabies Vaccine for Post-exposure Prophylaxis.

Completed · Phase 4

Conditions studied: Rabies

In brief

This is an exploratory trial to evaluate the effect of antimalarial drugs on the immune response generated by rabies vaccine when administered for post-exposure prophylaxis. This study will use the FDA approved post-exposure prophylaxis vaccine regimen (without rabies immune globulin) in the presence or absence of an FDA-approved malaria chemoprophylaxis regimen.

• Previous history of receiving the rabies vaccine.

• Any major psychiatric disorder, such as severe depression, severe anxiety disorder, psychosis, schizophrenia, other major psychiatric disorders, or seizures. History of mild depression or anxiety disorder that are well controlled are not exclusion criteria.
• Use of any immunosuppressive drug at the time of the study or 30 days previously. Topical steroids will not be considered an immunosuppressive drug and their use will not be considered an exclusion criteria.

• History of renal insufficiency or requiring dialysis.
• Have any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.

• Temporary Exclusion Criteria: Moderate or severe acute illness/infection (according to investigator judgment) or febrile illness (temperature ≥ 38.0°C [≥ 100.4°F]) on day 0.. A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided. If the delay for the febrile illness exceeds the window between screening and vaccination, or if deemed necessary by the investigator, a prospective subject may be re-screened once the fever has resolved.
