COVID-19
Conditions
Brief summary
Off label study to evaluate the efficacy of HCQ for pre-exposure prophylaxis (PrEP) to prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. 350 participants will be assigned to the group that takes HCQ or the group that opts to not take the study medication. Participants will be NYULH HCW at high risk for occupational exposure to SARS-CoV-2. Study timepoints will include screening/enrollment, 30 day, 60 day, and 90 day visits. Questionnaires, and DBS will be collected in all timepoints.
Detailed description
Hydroxychloroquine (HCQ) is licensed for the chemoprophylaxis and treatment of malaria and as a disease modifying antirheumatic drug. It has a long history of being safe and well tolerated at typical doses. HCQ has antiviral activity in vitro against coronaviruses, and specifically Covid-19. This study is designed to evaluate the efficacy of hydroxychloroquine (HCQ) for pre exposure prophylaxis (PrEP) to prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among health care workers at high risk of occupational exposure to SARS-CoV-2 compared to the eligible cohort that declines treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in the Number of Participants With Seroconversion to SARS-CoV-2 at 1 Month | Baseline to 1 month post-baseline | Antibody titers will be measured to determine seroconversion, a binomial endpoint defined by a four-fold increase in antibody titers compared to baseline. |
| Number of Participants With Symptomatic vs. Asymptomatic Seroconversion | 4 Weeks Prior to Baseline | To characterize whether high-risk HCW who seroconvert to SARS-CoV-2 have asymptomatic infection or report symptoms of COVID-19 in the 4 weeks preceding seroconversion (assessed by symptom questionnaire). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With of AEs or SAEs Possibly, Probably, or Definitely Related to HCQ Upon Study Termination Time | Day 90 | To assess the tolerability of hydroxychloroquine SARS-CoV-2 PrEP in this population |
