Brief Summary:

To test if the medication Hydroxychloroquine will decrease the amount of virus(as measured by PCR) , 7 days after initiation of therapy compared to control patients receiving placebo.

The study design is a randomized (5 days of medication v. 5 days of placebo) clinical trial initiated immediately after diagnosis in ambulatory health care workers at University of South Alabama Health, or in ambulatory USA patients. At 7 days after enrollment another nasopharyngeal swab will be taken to measure if the virus is still present. At 10 weeks we will measure immunity from Covid-19 using a single blood sample. It is a phase 2/3 clinical trial.


Condition or disease Intervention/treatment Phase
Covid 19 Corona Virus Infection Drug: Hydroxychloroquine Other: Placebo Phase 2 Phase 3

Detailed Description:
Hydroxychloroquine (HCQ), which is a less toxic derivative of chloroquine (CQ), has been shown to be effective in inhibiting Covid-19 infection in vitro. The evidence from clinical research trials is sparse and has many flaws. Much of the Chinese experience with Chloroquine comes from a letter to the editor and a news briefing/conference held on February 15, 2020. The letter describes experience with more than 100 patients treated with CQ in multicenter clinical trials but the letter provides no quantitative data to back their claims. At least one non-randomized clinical trial has been performed in Europe. Covid-19 infected patients received 10 days of HCQ daily and underwent daily testing of viral loads from nasopharyngeal swabs. The subjects receiving HCQ were much more likely (P<0.02) to clear their viral load than subjects who did not receive HCQ. The study had many flaws, which make the conclusions less valuable than rigorously designed randomized clinical trial. This study is designed as a randomized, blinded trial to either confirm or refute the efficacy of HCQ in early treatment of Covid19 infection to ameliorate disease severity, and reduce viral load.

    Nasopharyngeal swab PCR measurement of viral load expressed as the % of negative PCR swabs

  2. Disease Severity [ Time Frame: 6 days ]
    Participants will self-report disease severity status as one of the following 5 options; no COVID19 illness (score of 1), COVID19 illness with no hospitalization (score of 2), or COVID19 illness with hospitalization (score of 3), or Covid 19 with care requiring hospitalization (score of 4), or Covid 19 with death (Score of 5) .


Secondary Outcome Measures :
  1. Number of Participants Who Are Hospitalized for Covid 19 Infection [ Time Frame: 14 days ]
    Number of subjects in each arm who are hospitalized for Covid 19 infection

  2. Number of Participants Who Die Secondary to Covid 19 Infection [ Time Frame: 70 Days (10 weeks) ]
    Number of subjects in each arm who die secondary to Covid-19 infection

  3. Number of Participants Who Have Confirmed Covid 19 Infection [ Time Frame: 14 days ]
    Number of subjects in each arm who have confirmed Covid-19 infection

  4. Number of Participants Who Discontinue or Withdraw Medication Use for Any Reason [ Time Frame: 14 days ]
    Number of subjects in each arm who discontinue or withdraw medication use for any reason

  5. Immunity to Covid-19 [ Time Frame: 70 days (10 weeks) ]
    Blood tests to determine level of immunity in each subject
