Descriptive Information

• Brief Title: Outcomes Related to COVID-19 Treated With Hydroxychloroquine Among In-patients With Symptomatic Disease
• Official Title: Outcomes Related to COVID-19 Treated With Hydroxychloroquine Among In-patients With Symptomatic Disease
• Brief Summary: ORCHID is a multicenter, blinded, placebo-controlled, randomized clinical trial evaluating hydroxychloroquine for the treatment of adults hospitalized with COVID-19. Patients, treating clinicians, and study personnel will all be blinded to study group assignment.

Detailed Description

Effective therapies for COVID-19 are urgently needed. Hydroxychloroquine is an antimicrobial agent with immunomodulatory and antiviral properties that has demonstrated in vitro activity against SARS-CoV-2, the virus that causes COVID-19. Preliminary reports suggest potential efficacy in small human studies. Clinical trial data are needed to determine whether hydroxychloroquine is effective in treating COVID-19.

Study Aim: To compare the effect of hydroxychloroquine versus placebo on clinical outcomes, measured using the COVID Ordinal Outcomes Scale at Day 15, among adults with COVID-19 requiring hospitalization.

Study Hypothesis: Among adults hospitalized with COVID-19, administration of hydroxychloroquine will improve clinical outcomes at Day 15.

.

• Study Type: Interventional
• Study Phase: Phase 3

Study Design

Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Eligible participants will be randomized 1:1 to hydroxychloroquine versus placebo. Randomization will be stratified by site and be in permuted blocks of variable size.

Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:

Patients, treating clinicians, trial personnel, and outcome assessors will be blinded to group assignment.

Primary Purpose: Treatment

Condition

• Coronavirus
• Acute Respiratory Infection
• SARS-CoV Infection

Intervention

• Drug: Hydroxychloroquine

  Hydroxychloroquine is available in 200 mg oral tablets of hydroxychloroquine sulfate.

  For this COVID-19 trial, we will use an oral or enteral dose of hydroxychloroquine 400 mg twice daily on the day of enrollment, then 200 mg twice daily for the next 4 days for a 5 day total course.

• Drug: Placebo
  Participants randomized to the control group will receive a dose of placebo enterally twice daily for 5 days (a total of 10 doses). The placebo pills will be as similar as possible to the hydroxychloroquine pills to ensure blinding.

Study Arms

• Active Comparator: Hydroxychlorquine
  Participants assigned to the hydroxychloroquine arm will receive hydroxychloroquine sulfate 400 mg twice daily on the day of enrollment, then 200 mg twice daily for the next 4 days for a 5 day total course.
  Intervention: Drug: Hydroxychloroquine
• Placebo Comparator: Placebo
  Participants randomized to the control group will receive a dose of placebo enterally twice daily for 5 days (a total of 10 doses). The placebo pills will be as similar as possible to the hydroxychloroquine pills to ensure blinding.
  Intervention: Drug: Placebo
