|Prophylaxis COVID-19 Health Care Worker Hydroxychloroquine||Drug: Hydroxychloroquine Pre-Exposure Prophylaxis Drug: Placebo oral tablet||Phase 3|
This is a double-blinded, randomized placebo-controlled trial to determine if pre-exposure prophylaxis (PrEP) with 400mg hydroxychloroquine (HCQ), taken orally once daily, for health care workers in the hospital reduces symptomatic and asymptomatic COVID-19 disease during the pandemic.
Secondary outcomes include 1) Adverse events; 2) Duration of symptomatic COVID-19 disease; 3) Days hospitalized attributed to COVID-19; 4) Respiratory failure attributable to COVID-19 disease requiring i) non-invasive ventilation or ii) intubation/mechanical ventilation; 5) Mortality attributed to COVID-19 disease, and; 6) Number of days unable to work attributed to COVID-19. Laboratory markers within participants with confirmed COVID-19 will also be explored.
A total of 374 HCW will be randomized using a fixed 1:1 allocation ratio with randomization in permuted block of varying sizes from four to eight will be used to ensure equal allocation to each group. The study population will be health care workers at the New York Presbyterian Hospital - Cornell Campus and they will participate in the study for 90 days.
To determine if the intervention has been successful, the cumulative incidence of COVID-19 infection in the intervention group will be compared to the cumulative incidence of COVID-19 in the placebo group with relative (risk ratio and 95% CI) and absolute measures (risk difference and 95% CI). Investigators will also calculate adjusted risk ratios and risk differences including job class as a covariate and any other baseline clinical and demographic characteristics that are not balanced between the treatment and placebo arms using a log-binomial regression model.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||374 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||HCW are randomized to either the study drug (HCQ) or placebo.|
|Masking:||Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)|
|Masking Description:||Participants in the study will be randomized to either the investigational drug (HCQ) or placebo. The investigational drug and placebo will have identical appearance and be taken at the same frequency and dosage. The administration of the drug and assessment will be blinded. Study arms will be unmasked at the end of the study for the final analysis.|
