Clinical trial

Phase One, Open Label, Homologous Reinfection With Dengue-1-Virus-Live Virus Human Challenge - (DENV-1-LVHC) or Dengue-3-Virus-Live Virus Human Challenge (DENV-3-LVHC) Virus Strains

Name
2023-01-UMU
Description
Previous studies with one dengue infection in a controlled environment at Upstate generated data that has been important in understanding the clinical signs and symptoms and how a person's body reacts to dengue infection over time. This has helped investigators compare what is seen in the clinic to what is seen in areas where dengue is prevalent. The investigators want to collect similar information when a person gets the same dengue twice in a controlled environment with the hope that this will lead them to a better understanding of the disease. New participants * will receive one inoculation of dengue and then return to the clinic or be contacted by phone over 6 months; * will receive a second inoculation after 6 months and return to the clinic or be contacted by phone for three more months; * will collect saliva at home; * will allow the study team to collect blood and saliva at the clinic visits. Participants who have been in previous dengue inoculation studies at SUNY Upstate * will receive one inoculation of dengue and then return to the clinic or be contacted by phone over 6 months; * will collect saliva at home; * will allow the study team to collect blood and saliva at the clinic visits. All participants will be seen in the clinic every other day for the first three weeks after any inoculation.

Provide consent for release of medical history records from primary care physician, college or university, urgent care or emergency room visit Exclusion Criteria: 1. Female: pregnant or lactating 2. Heavy menstrual bleeding within the last 6 months- menstrual periods lasting longer than 6 days or requiring 5 or more pads or tampons per day, endometriosis or uterine scarring 3.

If the subject has previously screened negative for dengue in the last 12 months and has not traveled to an endemic area. The results of the previous screening will be used. 6. Any history of dengue infection or dengue vaccination (licensed or experimental) (cohorts 1 and 2); or planned dengue vaccination during the study period (all cohorts) 7. Recent (in the past 4 weeks) travel to any dengue endemic area or travel to a country with risk of yellow fever or Japanese encephalitis transmission 8. Positive urine screen for cocaine, amphetamines, opiates or methadone 9. Currently taking anti-coagulant medication, aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) 10. Active diabetes, active peptic ulcer disease (PUD), chronic obstructive pulmonary disease (COPD), coronary artery disease (CAD) 11. Known or suspected congenital or acquired immunodeficiency; or receipt of immunomodulation therapy such as anti-cancer chemotherapy or radiation therapy; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months) 12.
