NCT04352946

Brief Summary

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. 374 health care workers will be randomized at a 1:1 allocation between the intervention and placebo arms and followed for 90 days. 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).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Health care worker (HCW) at the hospital who work on a "full time" basis during the study period. For the purposes of the study, "health care workers" are physicians, nurses, nurse practitioners, physician assistants, respiratory therapists, X-ray technicians, social workers and support staff (including but not limited to house-keeping, and porters).
  • Age ≥18 years.
  • Ability to communicate with study staff in English

You may not qualify if:

  • Known hypersensitivity/allergy to hydroxychloroquine or to 4-aminoquinoline compounds.
  • Current use of hydroxychloroquine for the treatment of a medical condition.
  • Known prolonged QT syndrome, or concomitant medications which simultaneously may prolong the QTC that cannot be temporarily suspended/replaced. These are including but not limited to Class IA, IC and III antiarrhythmics; certain antidepressants, antipsychotics, and anti-infectives; domperidone; 5-hydroxytryptamine (5-HT)3 receptor antagonists; kinase inhibitors; histone deacetylase inhibitors beta-2 adrenoceptor agonists.
  • Known pre-existing retinopathy of the eye.
  • Disclosure of self-administered use of hydroxychloroquine or chloroquine currently under investigation \<4 weeks prior to study. This window is intended to account for the drug half-life of HCQ (21 days).
  • Baseline symptom of COVID-19 disease at enrollment and baseline viral detection specimen positive for SARS-COV-2. All participants with COVID-19 symptoms at enrollment will be directed to have confirmatory testing (within the department or occupational health as per the site guidelines). Participants who are negative for SARS-COV-2 will be redirected to enrollment procedures, those testing positive will be excluded.

Masking Details
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.
