Brief Summary:
This is a prospective, randomized, double-blinded, placebo-controlled, pilot study to assess the preliminary efficacy and safety of hydroxychloroquine for the treatment of patients with lower respiratory tract SARS-CoV-2 infection.

Condition or disease Intervention/treatment Phase
COVID-19 SARS-CoV-2 Drug: Hydroxychloroquine Drug: Placebo Phase 2

Detailed Description:

A total of 40 participants are planned for enrollment. Those enrolled into this study will be randomized 1:1 to receive either hydroxychloroquine or placebo control.

Participants will receive their study intervention for 5 days, after which they will be considered off protocol- directed therapy and receive medical management of their disease according to institutional standards. Participants may be followed for up to 180 days from initiating protocol therapy for clinical outcome, after which they will discontinue study participation.

Arm Intervention/treatment
Experimental: Hydroxychloroquine
400 mg bid (PO) Day 1, followed by 200 mg bid (PO) Day 2 through Day 5
Drug: Hydroxychloroquine
Hydroxychloroquine is more polar, less lipophilic, and has more difficulty diffusing across cell membranes than the parent compound, chloroquine. These characteristics result in hydroxychloroquine having a longer half-life, comparatively lower toxicity to chloroquine, as well as fewer concerns pertaining to drug-drug interactions

Placebo Comparator: Placebo
Placebo pill bid (PO) Day 1 through Day 5 of the treatment period
Drug: Placebo
A placebo is a pill that looks like the study drug but has no real medicine in it.

Primary Outcome Measures :
  1. Clinical Status at Day 5 Assessed by a 6-Point Ordinal Scale [ Time Frame: Day 5 ]
    A 6-point ordinal scale ranging from "Death" to "Not hospitalized with full resumption of normal activities" is used to evaluate differences in the clinical status between participants that receive placebo vs hydroxychloroquine

Secondary Outcome Measures :
  1. Number of Participants with Detectable SARS-CoV-2 Virus from Day 0 to Day 28 and at Day 5 [ Time Frame: Day 0 to Day 28 and at Day 5 ]
    Assess differences in SARS-CoV-2 viral shedding between participants that receive placebo vs hydroxychloroquine

  2. Toxicity of Study Drug Assessed by Incidence of Adverse Events [ Time Frame: Day 0 to Day 28 ]
    Assess by incidence of Grade 3, Grade 4, and Serious Adverse Events (AEs)

Other Outcome Measures:
  1. Duration of Initial Hospitalization [ Time Frame: Day 0 to Day 28 ]
    Assess length of hospitalization

  2. Mortality During Follow-Up [ Time Frame: Day 0 to Day 28 ]
    Assess number of deaths during study follow-up

  3. Mortality During Initial Hospitalization [ Time Frame: Day 0 to Day 28 ]
    Assess number of deaths in the hospital during initial hospitalization

  4. Incidence of New Hospital Resource Utilization [ Time Frame: Day 0 to Day 28 ]
    Assessing utilization of hospital resources

  5. Duration of Hospital Resource Utilization [ Time Frame: Day 0 to Day 28 ]
    Assessing duration of hospital resource utilization

  6. Changes in Cytokine Profile [ Time Frame: Day 0 to Day 28 ]
    Provide preliminary characterization of differences in inflammatory response between participants that receive placebo vs hydroxychloroquine

Inclusion Criteria:

  1. Ability to understand and the willingness to sign a written informed consent document.
  2. Individuals aged ≥ 18 years of all races and ethnic groups.
  3. Must have documented positive test result for SARS-CoV-2 (COVID19), or high clinical suspicion for SARS-CoV-2 based on presence of typical clinical findings (e.g., fever, respiratory symptoms, pulmonary abnormalities on chest X-ray or CT scan), lack of alternative diagnosis, and history of exposure to a known case of SARS-CoV- 2 infection within the past 14 days
  4. Not receiving institutional therapy for treatment of SARS-CoV-2, including (but not limited to) remdesivir, chloroquine, hydroxychloroquine, or any other investigational agent(s).
  5. Must meet at least one of the following clinical stratifications:

    1. Have at least 1 minor criterion per ATS criteria (refer to Appendix A), or
    2. Have fever, respiratory symptoms, with pneumonia visible on chest imaging (e.g., X-ray or computed tomography [CT]), or
    3. High risk for poor outcome, as defined by any one of the following:
