Clinical trial NCT04353037
Conditions: Coronavirus Corona Virus Infection

Start date: 2020-04-07; Completion date: 2020-07-11
Enrollment: 39 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
The proposed hypothesis is that high doses of hydroxychloroquine (HCQ) for at least 2 weeks can be effective antiviral medication both as a treatment in ambulatory patients and prophylaxis/treatment in health care workers because it impairs lysosomal function and reorganizes lipid raft (cholesterol and sphingolipid rich microdomains in the plasma membrane) content in cells, which are both critical determinants of Emerging Viral Disease (EVD) infection. This hypothesis is based on a growing literature linking chloroquine to antiviral activity. It is estimated that enough information exists to launch a clinical trial of hydroxychloroquine for COVID-19.

Detailed description:
Sub-Study 1: COVID-19 patients in self-quarantine. Group 1: Hydroxychloroquine 400 mg bid (two 200 mg tablets taken twice a day; totaling 800 mg per day) for two weeks; Group 2: Placebo 2 pills twice a day for two weeks

Sub-Study 2: Asymptomatic health care worker prophylaxis. Group 1: Hydroxychloroquine 600 mg once a day (three 200 mg tablets taken once a day) for up to 2 months; Group 2: Placebo 3 pills once a day for up to 2 months; cross-over from placebo to HCQ 600 mg once a day is allowed upon confirmatory diagnosis for COVID-19.

2.0 
BACKGROUND AND RATIONALE 
2.1 Overview of SARS-CoV-2 and Chloroquine Derivatives 
 
Chloroquine derivatives show preclinical efficacy against coronavirus but very little clinical data is 
available. Emerging viral diseases (EVDs) encompass a growing list of zoonotic viruses that have a major impact 
on global health and economics. These include Ebola, SARS, MERs, Marburg, and the recently identified virus 
that causes COVID-19 disease (Wuhan Coronavirus: SARS-CoV-2) (1). In each of these cases there is currently 
no effective drug treatments or prophylaxis agents that can be quickly applied to large populations at risk for the 
virus. As of March 2020, The SARS-CoV-2 virus has infected more than 180,000 people causing more than 5000 
deaths. This has led to a lockdown of entire megacities in China, international travel bans, and disruptions in 
global supply chains. More alarming is the recent evidence that health care workers are getting infected and dying 
of the virus, wreaking havoc on the chain of care.  In addition, while prior epidemics such as Ebola seemed to be 
contained in Africa, the current COVID-19 global crisis demonstrates how with the extent of globalization and 
international travel, no country is safe from these EVDs.   
 
Coronaviruses are a large family of viruses that commonly infect many animals, including camels, cattle, cats, 
and are often found in bats as their zoonotic reservoir. While it is rare, animal coronaviruses can infect people 
and then spread between people, as had occurred with Middle East respiratory coronavirus (MERS-CoV) and 
severe acute respiratory coronavirus (SARS-CoV), and now the newly emerged coronavirus SARS-CoV-2 (also 
known as COVID-19). The SARS-CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV.  All three 
of these viruses have their origins in bats. While SARS-CoV and MERS-CoV exhibit significantly higher 
mortality than SARS-CoV-2, the ability to spread between humans is less than SARS-CoV-2. There is emerging 
evidence from Asia that patients can be highly contagious with one patient spreading viral particles to 87% of 15 
sites within the patient’s room. Virus can be shed in urine and feces as well as respiratory secretions increasing 
the likelihood that sick contacts and hospital staff will become infected (2). An epidemiological survey of 72,000 
cases in China found and overall 3.8% infection rate in hospital workers, but a 68% infection rate of hospital 
workers in Wuhan at the epicenter of disease.  This suggests that if low rates of infection are in a community,  the 
likelihood of hospital workers  contracting disease is low, but if there are a large number of cases then the 
likelihood of hospital workers contracting the disease is high (3).   Patients above the age of 50 are more likely to 
die of this disease and the time from diagnosis to death can occur within one month despite access to high-level 
intensive care units (4). A high rate of intra-family transmission and rapid community transmission has been 
documented in Shenzen China (5).  Meanwhile a screen of compounds found that chloroquine prevented and 
eradicated established infection of SARS-CoV-2 virus in vitro. I was contacted by researchers in China who 
indicated that 8/10 coronavirus infected patients treated with chloroquine 500 mg daily cleared their virus. The 
hospital ran out of chloroquine, and they have had to turn to other means of treating the virus. We believe 
hydroxychloroquine is a safer drug than chloroquine and affords the ability to dose escalate to concentrations that 
we know are effective at blocking the lysosome in patients.   
 
Our hypothesis is that high doses of hydroxychloroquine for at least 2 weeks can be effective antiviral medication 
both as a treatment in ambulatory patients and prophylaxis/treatment in health care workers because it impairs 
lysosomal function and reorganizes lipid raft (cholesterol and sphingolipid rich microdomains in the plasma 
membrane) content in cells, which are both critical determinants of EVD infection. This hypothesis is based on a 
growing literature linking chloroquine to antiviral activity.  We believe there is enough information to launch a 
clinical trial of hydroxychloroquine for COVID-19.

2.2a Coronaviruses. Coronaviruses (CoV) infect mammals and birds causing respiratory, gastrointestinal, and 
central nervous system diseases. Coronavirus virions contain an envelope, a helical capsid, and a single-stranded 
RNA genome, the largest among all RNA viruses. The name “coronaviruses” derives from the spike proteins on 
their envelope that give the virions a crown-like shape. CoVs include the following: 1) α-genus:  human 
coronavirus NL63 (HCoV-NL63), porcine transmissible gastroenteritis coronavirus (TGEV), and porcine 
respiratory coronavirus (PRCV) 2) β-genus: SARS-CoV-2/COVID-19, severe acute respiratory syndrome 
coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), mouse hepatitis 
coronavirus (MHV), and bovine coronavirus (BCoV). 3) CoVs of the γ-genus include avian infectious bronchitis 
virus (IBV) and do not infect humans so are valuable laboratory agents (6). Coronaviruses impose health threats 
to humans and animals. SARS-CoV caused the SARS epidemic in 2002 to 2003, with over 8,000 infections and 
a fatality rate of ∼10%. MERS-CoV emerged from the Middle East in 2012 causing 877 infections with a fatality 
rate of ∼36%.  HCoV-NL63 from the α-genus is a widespread pathogen that produces the common cold in healthy 
adults and acute respiratory illness in young children. CoVs are also major animal pathogens.  TGEV and MHV 
cause close to 100% fatality in young pigs and young mice, respectively; BCoV and IBV also cause significant 
healthcare burden for domesticated cattle and chickens, respectively. Therefore, research on coronaviruses has 
strong health and economic implications (6). 
 
2.2b CoV infection requires functional lysosomes. Receptor recognition by viruses is the first and essential step of viral 
infections of host cells. An envelope-anchored spike protein mediates coronavirus entry into host cells by first binding to a 
receptor on the host cell surface and then fusing viral and host membranes. CoVs recognize a number of different host 
receptors. Once the receptor is bound, there is viral and cell membrane fusion, followed by endocytosis and lysosomal 
processing. CoVs like SARS enter the cell through lipid raft enriched endocytosis (7). The details of the interaction between 
the virus spike protein, virus membrane and the lipid rafts are not worked out. In the lipid raft literature, it is often the case 
that lipid rafts (semisolid phase membrane filled with cholesterol and sphingolipids) are only physiologically functional if 
there is a non-lipid raft membrane region next to it.  After membrane fusion, endosomal pH acidification is a fusion trigger 
for CoVs and other viruses including influenza virus and vesicular stomatitis virus (VSV). For instance the use of lysosomal 
inhibitor blocked the entry of the model coronavirus IBV (8). The authors directly assessed the pH dependence of IBV 
fusion and found that fusion only occurs at acidic pH. For some CoVs that harbor a non-cleaved spike protein on their 
surface, such as MHV-2 and SARS-CoV, it has been shown that they rely on lysosomal proteases for productive entry. In 
fact one study found that bat cells have more efficient lysosomal proteolysis than human cells providing an explanation for 
why bats are preferred zoonotic hosts for CoVs (9).  
 
2.2c Evidence that chloroquine prevents coronavirus infection. It has been reported that chloroquine has strong antiviral 
effects on SARS-CoV infection and spread in vitro (10-12). In to increasing endosomal/lysosomal pH, these studies 
demonstrated that CQ abrogates glycosylation of ACE2, the cellular receptor of SARS-CoV, which may contribute further 
to infection suppression. The IC50 of chloroquine for inhibition of SARS-CoV in vitro is 8.8 micromolar which would 
require higher concentrations than typically delivered in malaria. Importantly, the suppressive effects are observed when 
the cells are treated with chloroquine either before or after exposure to the virus, suggesting both prophylactic and 
therapeutic treatment paradigms could be employed (10, 11). The work by Kayaerts looked at human coronavirus OC43 
which causes neonatal death in mice. Treatment with chloroquine of pregnant mothers provided a 98.6% protection against 
death in newborn mice. This is in the only in vivo demonstration of chloroquine efficacy against a CoV.  DeWilde et al. 
screened a library of 348 FDA-approved drugs for anti- MERS-CoV activity in cell culture and only four compounds 
(chloroquine, chlorpromazine, loperamide, and lopinavir) were found to inhibit the viral replication (50% effective 
concentrations, EC50 3–8 lmol/L) (12). The protective activity of chloroquine against CoVs such as SARS, MERS and 
COVID-19 has not yet been established in animal models.  
 
2.2d Chloroquine is active against COVID-19/ SARS-CoV-2: A recent paper from Wuhan China isolated 
SARS-CoV-2 (the virus that causes COVID-19 disease) and tested 6 modern antiviral drugs and chloroquine and 
found that the best suppressors of viral infection were remdesivir (IC50 0.77 µmol) and chloroquine (IC50 1 
µmol) (13). Only chloroquine given at 10 µM was able to suppress infection either with pretreatment, at the time

of infection, or after infection occurred. This has led to clinical trials and off label use of chloroquine in China 
(Dr. Amaravadi personal communication with scientists in China). There are Chinese guidelines for the use of 
chloroquine 500 mg bid for the treatment of COVID-19 (Ref). In addition, an update provided by Chinese 
physicians suggests initial experience with chloroquine and/or hydroxychloroquine have been positive (ref).  
Hospitals have run out of chloroquine, and doctors are not confident on proper dosing of hydroxychloroquine. 
Careful clinical trials with optimized chloroquine derivatives would be well received in a hot zone.  
 
2.3 Clinical experience with high dose hydroxychloroquine in cancer patients 
 
In contrast to CQ, which can produce blindness at high cumulative doses, our recent body of work has 
demonstrated that high dose HCQ can be administered safely to humans for months. Our work on autophagy as 
a resistance mechanism to cancer therapy had identified CQ derivatives as potential anti-cancer agents (14). Since 
HCQ has had a longer track record of dose escalation and chronic dosing in rheumatoid arthritis and lupus, we 
chose HCQ as our lysosomal autophagy inhibitor to test in combination regimens in cancer patients. We reported 
the first 6 phase I dose escalation clinical trials involving HCQ in combination with FDA approved anti-cancer 
drugs in refractory stage IV cancer patients (15-20). In most patients on these trials we were able to escalate the 
dose of HCQ to 1200 mg per day and dose patients in some cases safely for more than one year. In over 220 
patients treated across multiple studies the rate of grade 3-4 non-hematological toxicities was < 10%. Most of 
these had more to do with the severity of the cancer and would likely not be seen in a healthy population. 
Specifically, no retinal, cardiac, neurological, hepatic or renal toxicity was observed. Hematological toxicities 
could be attributed to the other cancer drug (chemotherapy) that HCQ was paired with, and the most common 
side effects included manageable gastrointestinal symptoms such as bloating, diarrhea, constipation and mild non-
bloody diarrhea. 
 
2.4 Low dose versus high dose HCQ 
 
In HCQ studies in cancer patients we conducted population pharmacokinetic studies and pharmacodynamic 
studies and determined that 800-1200 mg daily was required to effectively and consistently impair the lysosome 
in peripheral blood mononuclear cells. Our PK studies determined that it took roughly 2 weeks to achieve steady 
state in cancer patients. For these reasons there is rationale to propose a high dose (600 mg po bid) prolonged 
schedule treatment (2 weeks). In contrast an in vitro study recently published which included PK-PD modeling 
extrapolated from published PK studies indicated that HCQ was very active against COVID-19 but only 400 mg 
po bid X1 followed by 200 mg po bid for 5-10 days was enough for treatment. A recent non-randomized open 
label French trial Geuret et al Int J Antimicrobial Agents 2020) showed that 600 mg qd of HCQ cleared virus in 
70 % of mildly ill hospitalized patients compared to 12.5% at 6 days of control patients. This generates a major 
question in how to use this agent in different populations that can best be answered in this two-part placebo 
controlled randomized trial.

5. Package containing blinded study drug supply, study journals (medicine log, symptom tracker and 
experience log) and study documents (details on aims, design, consent forms, and any additional 
instructions) are delivered to the address provided by participant as place of residence during study. 
Delivery of blind study drug supply will occur in two shipments, each containing a 30-day supply. Day 1 
is defined as the first day the blinded study drug is taken by the participant. 
6. Each day active medication is taken (HCQ or placebo), participants will record 1) temperature (to be 
reported twice daily, either via thermometer or self-report); 2) time medication taken; and 3) any 
symptoms and AEs. 
7. Every week, clinical research coordinators will review the study portal to assess for AEs and indication 
of reported symptoms indicative of influenza like illness.  The research coordinator will also review self-
reported fever and/or temperature.  If COVID-19 symptoms are evident, the research coordinator will 
outreach to the HCW (at clinic or by phone). Clinical research coordinators may clinically escalate any 
medical determinations to Co-PI following study portal review. 
8. The HCW also has access to the study coordinators via the study phone number.  If the HCW feels 
symptomatic, then he/she should call the clinical research coordinator team, and document symptoms in 
the study portal. Clinical research coordinators may clinically escalate any medical determinations to Co-
PI. 
9. If during the study symptoms indicative of an influenza like illness present, participant will be asked to 
comply with their employer’s potential or confirmed COVID-19 incident protocol and be tested for 
COVID-19 by an accepted method. Participants negative for COVID-19 continue with the assigned 
blinded study drug regimen. 
10. If confirmed COVID-19 diagnosis, participant will be unblinded. Participants assigned to HCQ can 
continue with medication schedule. Individuals assigned to the placebo arm will be offered the 
opportunity to cross-over to HCQ 600 mg daily for 14 days. Individuals will be expected to continue 
self-reporting temperature, time medication taken and any symptoms/AEs into the study portal while 
taking active HCQ medication.

be asked to undergo COVID-19 and serology testing for IgM/IgG on either Day 61, 62, or 63. 
 
5.0 RANDOMIZATION 
Randomization will be done using computer generated randomization numbers. Randomization will be 
stratified by age. Treatment will start upon receipt of the product by the patient after enrolling in the 
study, notifying the pharmacy and having the product/placebo sent.  
 
Blinding: Both sub-studies will have a double-blind placebo-controlled design.   
 
Unblinding: (See study process flows) 
o For PATCH 2 (Sub-study 1), If patient in PATCH 2 experiences worsening of symptoms, a Co-PI will 
be notified to take appropriate clinical action. Co-PI can choose to unblind for clinical determinations.  
 
o For PATCH 3 (Sub-Study 2), confirmation of a COVID-19 diagnosis would trigger the unblinding 
pathway for a participant (for details see Section 4.0, Participant Registration, PATCH 3 (Sub-Study 2) 
Participant Procedure).

6.0 TREATMENT PLAN    
PATCH 2 (Sub-Study 1) 500 patients with 2 interim analyses  
• 
Arm 1 (HCQ): Hydroxychloroquine 400 mg bid (two 200 mg tablets taken twice a day; totaling 800 mg per day) 
for 14 days 
• 
Arm 2 (Placebo): Two pills taken twice daily (totaling four pills each day) for 14 days 
 
PATCH 3 (Sub-Study 2) 350 participants with 2 interim analyses 
• 
Arm 1 (HCQ): Hydroxychloroquine 600 mg qd (three 200 mg tablets taken once day) for 60 days 
• 
Arm 2 (Placebo): Three pills once a day for 60 days with optional crossover to HCQ 600 mg qd for 14 days upon 
presentation of symptoms indicative of an influenza like illness and subsequent confirmatory diagnosis for 
COVID-19 
 
7.0 DETAILS OF STUDY TREATMENT 
7.1a Hydroxychloroquine 
Mechanism of Action: The mechanism of action is not fully understood. Previously it was thought that HCQ 
and other chloroquine derivatives are weak bases that deacidify lysosomes through purely chemical basis. 
Recently our group has identified the missing molecular target of HCQ as palmitoyl protein thioesterase 1 
(PPT1).

Storage and formulation: HCQ tablets are manufactured by a number of generic drug companies as well as Novartis. Each 
tablet contains 200 mg hydroxychloroquine sulfate (equivalent to 155 mg base). It is dispensed in a tight, light-resistant 
container as defined in the USP/NF.HCQ should be stored at room temperature up to 30° C (86° F). 
Pharmacokinetics: The PK of HCQ is characterized by a large volume of distribution, binding to red blood 
cells, and long time to peak concentration and steady state. Population PK studies in cancer patients have 
demonstrated dose proportional change in exposure. 
Administration: Hydroxychloroquine is an oral medication available in 200 mg tablets. HCQ will be supplied 
by the study team via Avella Pharmacy. Tablets of HCQ are available in 200 mg strength. In PATCH 2 (Sub-
Study 1), HCQ will be administered in divided doses (every 12 hours) with each dose consisting of two 200 mg 
tablets (or 400 mg bid), totaling 800 mg daily. The two daily doses of HCQ should be taken 12 hours apart, 
for example, 9 am and 9 pm. In PATCH 3 (Sub-Study 2), HCQ will be administered as three 200 mg tablets 
taken once a day (600 mg qd) at the same time. Hydroxychloroquine sulfate tablets should be taken with a meal 
or a glass of milk. Participants will be required to keep a study journal and document the time HCQ doses are 
taken; journal completion will be reviewed by study staff. The HCQ schedule may be adjusted if necessary, to 
minimize gastrointestinal side effects. 
For complete information please refer to the package inserts at http://dailymed.nlm.nih.gov/dailymed/ 
 
7.1b Placebo 
 
There will be no active medication in the placebo tablets, which will be supplied by the study team via Avella 
Pharmacy and mailed to the participant’s provided address. In PATCH 2 (Sub-Study 1), placebo will be 
administered in two divided doses (every 12 hours) with each dose consisting of two tablets, totaling four 
tablets daily. The two daily doses of placebo should be taken 12 hours apart, for example, 9 am and 9 pm. In 
PATCH 3 (Sub-Study 2), placebo will be administered as three tablets taken once a day at the same time. 
Tablets should be taken with a meal or a glass of milk. Participants will be required to keep a study journal and 
document the time placebo doses are taken. The dosing schedule may be adjusted if necessary, to minimize, 
gastrointestinal side effects. Journal completion will be reviewed by study staff.  
 
7.2 Concomitant Medication, Drug-Drug interactions and Procedures 
Participants will be instructed not to take any medications, including over the counter products, without first 
consulting with the study team. The study phone number and additional contact information will be provided 
with the welcome packet, allowing for the study team to be contacted if the participant is seen by a health care 
provider or medications are changed. 
Drug Interactions  
Insulin or antidiabetic drugs: As HCQ may enhance the effects of a hypoglycemic treatment, a decrease 
in doses of insulin or antidiabetic drugs may be required.  
Drugs that prolong QT interval and other arrhythmogenic drugs: HCQ can prolong the QT interval and should 
not be administered with other drugs that have the potential to induce cardiac arrhythmias. Also, there may be 
an increased risk of inducing ventricular arrhythmias if HCQ is used concomitantly with other arrhythmogenic 
drugs.  
Antiepileptics: The activity of antiepileptic drugs might be impaired if co-administered with HCQ.

Cyclosporin: An increased plasma cyclosporin level was reported when cyclosporin and HCQ were 
co-administered.  
Because HCQ has known effects on P450 enzymes, participants requiring anti-convulsants may be treated with 
any of the non-enzyme inducing anti-convulsants which include: felbamate, valproic acid, gabapentin, 
lamotrigine, tiagibine, topiramate, or levetiracetam. Due to the fact that both zonisamide and HCQ accumulate 
in red blood cells, zonisamide should be avoided if possible. Other concomitant medications may be permitted. 
The following medications and treatments are not allowed during the study. The sponsor must be notified if the 
participant receives any of these during the study: 
1. PATCH 2 and 3 (Sub-Studies 1 and 2): Any investigational or off-label antiviral therapy  
2. Any concurrent chemotherapy, radiotherapy, immunotherapy, biologic or hormonal therapy for cancer 
treatment, except as noted in the exclusion criteria. Concurrent use of hormones for noncancer-related 
conditions (e.g. insulin for diabetes, hormone replacement therapy) is acceptable. 
3. Immunosuppressive medications, including, corticosteroids at doses exceeding 10mg/day of prednisone or 
equivalent, methotrexate, azathioprine, and TNF-alpha blockers. Use of immunosuppressive medication for the 
management of study treatment-related AEs or in subjects with contrast allergies is acceptable. In addition, use 
of topical, inhaled and intranasal corticosteroids is permitted 
4. Live attenuated vaccines during the study through 180 days after the last dose of both drugs 
 
7.3 Duration of Protocol Treatment and Follow-up.  
PATCH 2 (Sub-Study 1) duration of treatment is 14 days (two weeks) with follow-up with COVID-19 testing 
on Day 15, 16 or 17, and Day 29, 30 or 31 where Day 1 marks the first day blinded study drug is taken by the 
participant. 
  
PATCH 3 (Sub-Study 2) duration of treatment is up to 60 days with an option to cross-over for participants 
taking placebo upon presentation of symptoms indicative of an influenza like illness and testing positive for 
COVID-19 (or a COVID-19 diagnosis is made by a health care provider). Participants remaining undiagnosed 
for COVID-19 by Day 60 will undergo testing for SARS-CoV-2 and IgM/IgG antibodies on either Day 61, 62, 
or 63. The maximum study medication duration and follow-up testing is 63 days.  
 
7.4 Crossover from Control to HCQ arm.   
  
PATCH 2 (Sub-Study 1): There is no cross-over. 
 
PATCH 3 (Sub-Study 2): Participants that develop symptoms indicative of an influenza like illness and 
diagnosed with COVID-19 will be unblinded. If they were assigned to the placebo arm and deemed appropriate, 
they will be offered the option crossover to HCQ 600 mg qd for 14 days.

8.0 TOXICITY CRITERIA, MONITORING, DOSE DELAYS AND MODIFICATIONS 
8.1 Toxicity Criteria 
This study will utilize the DAIDS table for grading adult adverse events (AEs). A copy of the DAIDS grading 
system is available at: https://rsc.niaid.nih.gov/sites/default/files/daidsgradingcorrectedv21.pdf. All appropriate 
treatment areas should have access to a copy of the DAIDs grading table. 
8.2 Dose Delays 
Major Events are Grade 3 and 4 hematologic and non-hematologic toxicities that are not treatment related. 
Treatment should be delayed for major events if HCQ may further complicate the non-treatment related event.  
If a major event requires a delay of treatment, treatment must be delayed until toxicity is resolved (≤ Grade 2 or 
≤ Baseline). For treatment-related toxicities and major events, if toxicity is not resolved in ≤ 7 days, participant 
will be taken off treatment unless there is an exception granted by the medical monitor.  
8.3 Ocular toxicity 
The only toxicity that requires discontinuation of HCQ is retinopathy. Published literature indicates HCQ 
retinopathy is idiosyncratic and is uncommon in patients receiving HCQ for less than a few years. Our ongoing 
study of dabrafenib, trametinib, and HCQ (BAMM; NCTNCT02257424) found no clinically meaningful ocular 
toxicity in 10 patients studied extensively with serial ocular exams (21). Therefore, we have not included 
mandatory ocular exams in this protocol. However, if there is a visual field deficit, retinal vein occlusion, serous 
retinopathy, bullseye retinopathy, or retinal detachment, HCQ should be permanently discontinued. 
 
8.4 Participant Safety Monitoring and Data Collection 
Adverse events will be captured via self-report by participants within the study portal. Participants are 
instructed to contact the study team at the phone number provided in the Welcome Packet to report all adverse 
events. The study team will reach out to the participant to gather additional information surrounding the adverse 
event in order to complete DAIDS grading if necessary. Additional information pertaining to the adverse event 
will be captured within the study portal by the study team and reviewed by the PI’s for causality to study drug. 
Adverse events meeting seriousness criteria will be reported to the IRB as noted below.  
 
PATCH 2 (Sub-Study 1):  
Clinical Symptom Monitoring: Participants will be contacted three times per week to assess AEs and COVID-
19 symptoms and collect/review self-reported AE’s. Worsening COVID symptoms and/or new or worsening 
AE’s will be reviewed by the PI’s for causality to study drug. 
Temperature Measurements: Home quarantined participants will be asked to report twice daily either presence of 
fever or temperature and record the measurements.  
COVID-19/SARS-CoV-2 Testing: On Days 15-17 and 29-31, participants will undergo follow-up testing for 
COVID-19.  
Pill Count and Journal: Participants will be contacted three times per week and following the end of treatment to 
compare data entry on the portal and collect any missed entries over the phone.  
Monitoring Co-Inhabitants: Participants will be contacted three times per week to identify if any co-inhabitants 
have developed symptoms and/or tested positive for COVID-19. Participants will also be asked to provide a 
description of co-inhabitants’ symptomology, and time of positive testing for COVID-19 via self-reporting. 
 
PATCH 3 (Sub-Study 2):  
Adverse events will be captured solely based on participant self-reporting via the study portal and/or by calling 
the study team at the number provided in the Welcome Packet. The study team will review the portal for self-
reported AE’s not previously reported to the study team.  New AEs not previously reviewed which cannot be

graded based upon self-reported data within the portal will require follow-up from the study team to gather 
additional information from the participant. New or worsening AE’s will be reviewed by the PI”s for causality 
to study drug.  
COVID-19/SARS-CoV-2 testing: Upon the presentation of symptoms indicative of an influenza like illness, 
participants will be asked to undergo testing for SARS-CoV-2 virus. Participants undiagnosed for COVID-19 at 
Day 60 will also be tested for SARS-CoV-2 and IgM/IgG antibodies (via serology testing) on either Day 61, 62, 
or 63.  
Clinical Symptom monitoring: The study team will assess AEs, symptoms, and record temperature (either 
reported temperature or self-report of fever) for any participants taking active medication (placebo or HCQ).  
Worsening COVID symptoms and/or new or worsening AE’s will be reviewed by the PI’s for causality to study 
drug. The rate of conversion to receiving a positive COVID-19 test result in each arm at the 2-month mark will 
be used to assess the primary endpoint.   
Pill count and Journal: Participants will be contacted to compare data entry on the portal and collect any missed 
entries over the phone.  
 
Participants will be instructed to call 911 upon immediate presentation of the following symptoms as identified 
by the CDC as requiring emergency action: bluish lips or face; new confusion/dizziness or inability to arouse; 
persistent pain or pressure in the chest (not caused by coughing); and difficulty breathing (including severe 
shortness of breath and single word speech). 
 
Participant confidentiality is strictly held in trust by all personnel granted access to the trial data. Therefore, the 
study data, and all other information generated will be held in strict confidence. No information concerning the 
study, or the data will be released to unauthorized parties.  
 
The study investigators and study team, the research sponsor and its designees, personnel from ProHealth with 
authorized access to study data, government agencies, reviewing Institutional Review Board (IRB), regulatory 
agencies and/or company supplying study product may inspect all documents and records required to be 
maintained by the sponsor, including but not limited to, clinical, pharmacy and lab records for participants 
enrolled in the study. All applicable parties will permit access to such records.  
 
The participant’s study contact information will be securely stored within the online study portal for internal use 
during the study. At the end of the study, all records will continue to be kept in a secure location for as long as 
dictated by the reviewing IRB and institutional policies.  
 
Study participant research data, which is for purposes of statistical analysis and scientific reporting, will be 
transmitted to and stored at UHG R&D in a de-identified manner. This will not include participant’s contact or 
identifying information, unless otherwise specified in the informed consent form. Rather, individual participants 
and their research data will be identified by a unique study identification number. The study data entry and study 
management systems will be secured, and password protected. At the end of the study, study data will be de-
identified and may be made public.

8.5 Hydroxychloroquine Dose Reduction 
Any Adverse Event Grade 3 or higher requires HCQ to be withheld. Treatment may be resumed once toxicity is 
≤ Grade 2 according to the below Dose Reduction Schema (Table 1). If toxicity does not resolve or improve to 
≤ Grade 2 within 7 days, participant will be withdrawn from active treatment unless granted an exception by the 
Medical Monitor. Medical Monitor should be notified of all toxicities requiring dose withholding or dose 
adjustments via email or phone.  
  
Any AE = Grade 2 and attributed as possibly, probably or definitely related to HCQ will result in a dose 
reduction of HCQ as described in Table 1.  
 
If AE remains = Grade 2 following the first dose reduction and attributed as possibly, probably or definitely 
related to HCQ following the second dose reduction, then the participant should discontinue treatment.  
No more than 2 dose reductions are allowed. It is recommended that dose reductions occur at a minimum of 48 
hours apart.

Reported non-serious toxicities attributable to HCQ include nausea, anorexia, vomiting, constipation, diarrhea 
and rash.  For any of these AEs occurring at Grade < 2, HCQ may be continued and the AE managed with 
supportive care. For Any AE with a Grade ≥ 3, HCQ will be held until the toxicity improves to ≤ Grade 2, after 
which HCQ may be restarted at a reduced dose as described in Table 1.   
Example:  Management of diarrhea in randomized subjects   
Grade 1: (an increase in stool up to 3 per day) results in no change to HCQ 
Grade 2: (an increase in stool up to 4-6 per day) results in a Dose Reduction according to Table 1  
Grade 3+: (an increase in stool up to 7 or more per day) results in Withholding of HCQ until AE at 
Grade level 2 or less, followed by a reduction in dose per Table 1.   
9.0 ADVERSE EVENTS AND REPORTING 
The timely reporting of adverse events (including toxic deaths) is required by the Food and Drug 
Administration. The reporting of toxicities is part of the data reporting for this study. The investigator is 
responsible for ensuring that all adverse events (AEs) and serious adverse events (SAEs) as self-reported during 
the study are collected and reported to the FDA, appropriate IRB(s), in accordance with CFR 312.32 (IND 
Safety Reports).

9.1 Adverse Events Definition 
An adverse event (AE) is any symptom, sign, illness or experience that develops or worsens in severity during 
the study that does not necessarily have a causal relationship with this treatment. Intercurrent illnesses or injuries 
should be regarded as adverse events. Abnormal results of diagnostic procedures are considered to be adverse 
events if the abnormality: 
• results in study withdrawal 
• is associated with a serious adverse event 
• is associated with clinical signs or symptoms 
• leads to additional treatment or to further diagnostic tests or considered by the investigator to be of clinical 
significance 
9.2 Adverse Events Reporting Period 
The study period during which adverse events must be reported is defined as the period from the initiation of 
the first study treatment to the last administration of study treatment. 
9.3 Adverse Events Post Study 
All unresolved adverse events at the conclusion of the dosing period should be followed by the investigator 
until the event is resolved, the participant is lost to follow-up, or the adverse event is otherwise explained. At 
the last scheduled contact, the study staff should instruct each participant to report any subsequent event(s) that 
the participant, or the participant’s personal physician, believes might reasonably be related to participation in 
this study. 
9.4 Adverse Events Assessment and Recording 
At each contact with the participant, the investigator or study staff will assess for information on adverse events 
and review all self-reported AE’s via the study portal. Information surrounding adverse events should be 
recorded in the study portal. Related signs, symptoms, and abnormal diagnostic procedures results should be 
recorded in the study portal and grouped under one diagnosis as applicable. 
Adverse events can be spontaneously reported or elicited during open-ended questioning. Adverse events will 
be measured and graded in accordance with the document entitled Division of AIDS (DAIDs) Table for Grading 
the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1, July 2017 issued by the US 
Department of Health and Human Services. The clinical course of each event should be followed until 
resolution, stabilization, or until it has been determined that the study treatment or participation is not the cause. 
Serious adverse events that are still ongoing at the end of the study period must be followed up to determine the 
final outcome. Any serious adverse event that occurs after the study period and considered to be at least 
possibly related to the study treatment or study participation should be recorded and reported immediately. 
9.4.1 Relationship to Study Drug 
The causal relationship can be one of the following: 
• Related: There is a possible, probable or definite causal relationship between study drug 
administration and the AE 
• Not related: There is evidence suggesting a causal relationship to something other than the study 
drug.

This trial does not require any safety laboratory assessments. However, in the event a participant has a standard 
of care labs completed which are self-reported and meet the DAIDS criteria for Grade 2 or greater, and cannot 
be attributed to another cause, study drug should be held and or reduced in accordance with section 8 above. 
 
9.6 Diagnosis vs. Signs and Symptoms 
If known at the time of reporting, a diagnosis should be reported rather than individual signs and symptoms 
(e.g., record only liver failure or hepatitis rather than jaundice, asterixis, and elevated transaminases). However, 
if a constellation of signs and/or symptoms cannot be medically characterized as a single diagnosis or syndrome 
at the time of reporting, it is ok to report the information that is currently available. If a diagnosis is 
subsequently established, it should be reported as follow-up information. 
9.7 Preexisting Medical Conditions 
A preexisting medical condition is one that is present at the start of the study. Such conditions should be 
reported as medical and surgical history. A preexisting medical condition should be re-assessed throughout the 
trial and reported as an AE or SAE only if the frequency, severity, or character of the condition worsens during 
the study. When reporting such events, it is important to convey the concept that the preexisting condition has 
changed by including applicable descriptors (e.g., “more frequent headaches”). 
10.0 SERIOUS ADVERSE EVENTS 
A serious adverse event is any AE that is: 
• fatal 
• life-threatening 
• requires or prolongs hospital stay 
• results in persistent or significant disability or incapacity 
• a congenital anomaly or birth defect 
• a suspected transmission of an infectious agent (e.g., pathogenic or nonpathogenic) via the study drug 
• an important medical event 
• All Serious Adverse Events (SAEs) that occur following the participant’s written consent to participate in 
the study must be reported, whether related or not related to study drug. If applicable, SAEs must be 
collected that relate to any later protocol-specified procedure. 
• Following the participant’s written consent to participate in the study, all SAEs, whether related or not 
related to study drug, are collected, including those thought to be associated with protocol-specified 
procedures. The investigator should report any SAE occurring after these aforementioned time periods, 
which is believed to be related to study drug or protocol-specified procedure. 
• An SAE report should be completed for any event where doubt exists regarding its seriousness; 
• If the investigator believes that an SAE is not related to study drug but is potentially related to the 
conditions of the study (such as withdrawal of previous therapy or a complication of a study procedure), the 
relationship should be specified in the narrative section of the SAE Report Form. 
All SAEs should be followed to resolution or stabilization. Serious adverse events that are ongoing at the end of 
the study period must be followed to determine the outcome. Any serious adverse event that occurs after the 
study period and is at least possibly related to the study treatment or study participation should be recorded and 
reported immediately to the Medical Monitor and the IRB per the IRB reporting guidelines.

23 
 
All adverse events that do not meet any of the criteria for serious should be regarded as non-serious adverse 
events. 
10.1 Important Medical Event 
Important medical events are those that may not be immediately life threatening but are clearly of major clinical 
significance. They may jeopardize the participant and may require intervention to prevent one of the other 
serious outcomes noted above. For example, drug overdose or abuse, a seizure that did not result in in-patient 
hospitalization, or intensive treatment of bronchospasm in an emergency department would typically be 
considered serious. 
10.2 Hospitalization, Prolonged Hospitalization or Surgery 
Any adverse event that results in hospitalization or prolonged hospitalization should be documented and 
reported as a serious adverse event unless specifically instructed otherwise in this protocol. Any condition 
responsible for surgery should be documented as an adverse event if the condition meets the criteria for an 
adverse event. 
Neither the condition, hospitalization, prolonged hospitalization, nor surgery are reported as an adverse event in 
the following circumstances: 
• Hospitalization or prolonged hospitalization for diagnostic or elective surgical procedures for a preexisting 
condition. Surgery should not be reported as an outcome of an adverse event if the purpose of the surgery 
was elective or diagnostic and the outcome was uneventful. 
• Hospitalization or prolonged hospitalization required to allow efficacy measurement for the study. 
• Hospitalization or prolonged hospitalization for therapy of the target disease of the study, unless it is a 
worsening or increase in frequency of hospital admissions as judged by the clinical investigator. 
Expected adverse events are those adverse events that are listed or characterized in the Package Insert or current 
Investigator Brochure. 
Unexpected adverse events are those not listed in the Package Insert (P.I.) or current Investigator Brochure 
(I.B.) or not identified. This includes adverse events for which the specificity or severity is not consistent with 
the description in the P.I. or I.B. For example, under this definition, hepatic necrosis would be unexpected if the 
P.I. or I.B. only referred to elevated hepatic enzymes or hepatitis. 
10.3 Deaths 
All deaths that occur during the protocol-specified AE reporting period (see Section 12.1), regardless of 
attribution, will be reported to the appropriate parties. When recording a death, the event or condition that 
caused or contributed to the fatal outcome should be reported as the single medical concept. If the cause of 
death is unknown and cannot be ascertained at the time of reporting, report “Unexplained Death”. 
10.4 Pregnancy 
If a female subject becomes pregnant while receiving investigational therapy or within 120 days after the last 
dose of study drug, the investigator must immediately notify the Sponsor in accordance with SAE reporting 
guidelines. Follow-up to obtain the outcome of the pregnancy should also occur. Abortion, whether accidental, 
therapeutic, or spontaneous, should always be classified as serious, and expeditiously reported as an SAE. 
Similarly, details of the birth, and the presence or absence of any congenital anomaly/birth defect or maternal 
and/or newborn complications in a child born to a female subject exposed to the study drug should be reported 
as an SAE. Follow-up information regarding the course of the pregnancy, including perinatal and neonatal 
outcome and, where applicable, offspring information must be reported. In order for Sponsor or designee to

disclosure of this information. Any pregnancy that occurs in a female partner of a male study participant should 
be reported. Information on this pregnancy will be collected on the Pregnancy Surveillance Form. In order for 
Sponsor or designee to collect any pregnancy surveillance information from the female partner, the female 
partner must sign an informed consent form for disclosure of this information. 
 
11.0 IRB NOTIFICATION  
The UHG IRB requires expedited reporting of those events related to study participation that are unforeseen and 
indicate that participants or others are at increased risk of harm. The IRB will not acknowledge safety reports or 
bulk adverse event submissions that do not meet the criteria outlined below. The IRB requires researchers to 
submit reports of the following problems within 10 working days from the time the investigator becomes aware 
of the event: 
• Any adverse event (regardless of whether the event is serious or non-serious, on-site or off-site) that 
occurs any time during or after the research study, which in the opinion of the principal investigator is: 
Unexpected (An event is “unexpected” when its specificity and severity are not accurately reflected in the 
protocol-related documents, such as the IRB-approved research protocol, any applicable investigator brochure, 
and the current IRB-approved informed consent document and other relevant sources of information, such as 
product labeling and package inserts.) 
AND 
Related to the research procedures (An event is “related to the research procedures” if in the opinion of the 
principal investigator or sponsor, the event was more likely than not to be caused by the research procedures.) 
Deaths occurring for participants on-study and within 30 days of study drug administration that are considered 
unforeseen and indicates participants or others are at increased risk of harm (i.e. unexpected and 
probably/definitely related), must be reported to the IRB within 24 hours of notification. 
Copies of each report and documentation of IRB notification and receipt will be kept in the Clinical 
Investigator’s study file. 
For clinical drug trials, the following events are also reportable to the IRB: 
• Any adverse experience that, even without detailed analysis, represents a serious unexpected adverse 
event that is rare in the absence of drug exposure (such as agranulocytosis, hepatic necrosis, Stevens-
Johnson syndrome). 
• Any adverse event that would cause the sponsor to modify the investigators brochure, protocol or 
informed consent form, or would prompt other action by the IRB to assure protection of human 
participants. 
• Information that indicates a change to the risks or potential benefits of the research, in terms of severity 
or frequency. For example: 
-- An interim analysis indicates that participants have a lower rate of response to treatment than initially 
expected. 
-- Safety monitoring indicates that a particular side effect is more severe, or more frequent than initially 
expected.

-- A paper is published from another study that shows that an arm of your research study is of no 
therapeutic value. 
• Change in FDA safety labeling or withdrawal from marketing of a drug, device, or biologic used in a 
research protocol. 
• Breach of confidentiality 
• Change to the protocol taken without prior IRB review to eliminate apparent immediate hazard to a 
research participant. 
• Incarceration of a participant when the research was not previously approved under Subpart C and the 
investigator believes it is in the best interest of the participant to remain on the study. 
• Complaint of a participant when the complaint indicates unexpected risks, or the complaint cannot be 
resolved by the research team. 
• Protocol violation (meaning an accidental or unintentional deviation from the IRB approved protocol) 
that in the opinion of the investigator placed one or more participants at increased risk or affects the 
rights or welfare of participants. 
The IRB will accept other reports when the investigator is unsure whether the event should be reported, and the 
IRB will review such reports to determine whether the event meets the threshold for an unanticipated event 
presenting risk to the participant.  Reports requiring IRB consideration or consultation are to be emailed to 
Tracy Ziolek, Vice President, Human Research Affairs at UnitedHealth Group at tracy_ziolek@uhg.com. 
 
11.1 Reporting Process to IRB. 
Principal Investigators are encouraged to submit reports of unanticipated problems posing risks to participants 
or others via a written report of the event (including a description of the event with information regarding its 
fulfillment of the above criteria, follow-up/resolution and need for revision to consent form and/or other study 
documentation) within 7 working days to the UnitedHealth Group Office of Human Research Affairs (OHRA).  
Participating sites should follow local, institutional guidelines on Event Reporting. For reportable deaths, the 
initial submission to the IRB may be made by contacting Tracy Ziolek at tracy_ziolek@uhg.com. 
This study is IND exempt and reporting to the FDA is voluntary using a MedWatch 3500 or via the FDA’s 
website for voluntary reporting. 
12.0 PARTICIPANT WITHDRAWAL 
Each participant has the right to withdraw from the study at any time without prejudice. The investigators may 
discontinue any participant’s participation for any reason, including adverse event or failure to comply with the 
protocol. Should a participant withdraw from the study, the reason(s) must be recorded within the study portal.  
Reasons for withdrawal include the following: 
• Progression of Disease: Remove participant from study at the time progressive disease is documented. 
• Extraordinary Medical Circumstance: If at any time the treating physician feels constraints of this protocol 
are detrimental to the participant’s health the participant should be withdrawn. 
• Participant’s refusal to continue treatment: In this event, document the reason(s) for treatment refusal. 
• Failure to comply with protocol (as judged by the investigator such as compliance below 80%, failure to 
maintain appointments, etc.). 
• Delay in treatment > 7 days due to toxicity or ongoing toxicity ≥ Grade 2 following two (2) dose 
reductions.

13.0 MEDICAL MONITORING 
It is the responsibility of the investigators to oversee the safety of the study at their site. This safety monitoring 
will include careful assessment and appropriate reporting of adverse events, as noted above, as well as the 
construction and implementation of a site data and safety monitoring plan. Medical monitoring by an independent 
clinician, will include a regular assessment of the number and type of serious adverse events on a periodic basis.   
13.1 Study Monitoring Plan 
This study will be monitored by the investigators and sub-investigators, as appropriate. Such monitoring will 
include at least weekly meetings of the study team to review accrual, toxicity, SAEs. Dose escalations and study 
finding. In addition, the PI will ensure that data are completed in a timely manner and their designee will review 
the data for accuracy, completeness and integrity.  
13.2 Auditing and Inspecting 
The investigator will permit the Office of Human Research Affairs, UnitedHealth Group to review records, data 
and facilities at mutually agreeable times. This study will be audited on an as needed basis with a complete review 
occurring at completion of enrollment. If enrollment numbers are not met, audit will occur in alignment with 
being notified of closure of the trial.

15.0 MEASUREMENT OF EFFECT 
15.1 Definitions 
Evaluable for toxicity:  All participants will be evaluable for toxicity from the time of their first treatment with 
HCQ or placebo through final assessment. 
Evaluable for primary outcome: Participants who received at least one continuous week of HCQ will be evaluable 
for the primary outcome.   
15.2 Response Criteria 
PATCH 2 (Sub-Study 1): Measurement of SARS-CoV-2 positivity confirmed by an accepted testing method. 
Rate of hospitalization will be defined by a hospitalization occurring within 30 days of the date of participant 
enrollment. 
PATCH 3 (Sub-Study 2): Rate of COVID-19 infection will be defined by measurement of SARS-CoV-2 
identified by accepted testing methods.  
 
16.0 STATISTICAL CONSIDERATIONS 
16.1 Sample size calculation  
Because we are uncertain about the outcome values for both control (placebo) and treatment (HCQ) arms of the 
study, we will use group-sequential methods, allowing us to stop early for both efficacy and futility.  We conduct 
two interim analyses and a final analysis, after approximately 1/3, 2/3, and 100% of participants have completed.

PATCH 2 (Sub-Study 1), Home quarantined patients with COVID-19: We will assume the null 
hypothesis that in the placebo arm 70% will recover without requiring hospitalization. For the low dose HCQ 
cohort 95% of home quarantined patients recover without requiring hospitalization. We will continue to 
enroll and randomize patients at the time of testing 1:1 HCQ to control until we reach at least 100 patients 
with at least 50 in the low dose HCQ arm and at least 50 in the placebo arm who have tested positive 
COVID19. The one-sided z- test (alpha=.05) will have an at least 90% power to detect a significant difference 
between the groups of greater than 25% between the population rates. We estimate we will need to enroll 500 
patients at the time of testing to reach the 100 patients who test positive for COVID19. 
 
The hypothesis will be tested with only patients who tested positive for COVID19 using a one-sided test, 
with a z-score corresponds to the log of the odds-ratio for recovery between the two groups. We will obtain 
the estimate of the odds ratio, and 95% CI, from logistic regression. As a secondary analysis, we will stratify 
the analysis, and obtain separate estimates of the odds-ratio by group. However, we are not powered to test 
the interaction for significance, and we do not expect significance within group.   
 
 
Interim analysis: We will perform two interim analyses at 34% and 68% completion, testing for early efficacy 
or futility, using z-score boundaries that follow Hwang-Shih-DeCani alpha spending rules.  Following those 
rules, we have 90% power using 100% of the sample, if scenario is true.  
 
PATCH 3 (Sub-Study 2), Prophylaxis in Health Care Workers: The transmission of SARS-COV-2 from 
patient to hospital worker depends on many factors including specifics of standard care to prevent 
transmission, but especially on the number of patients seen at a given hospital or outpatient practice. Across 
China the reported hospital worker infection rate is 3.8%, but in Wuhan it is reported as 58% at the height of 
the epidemic. We will use a 10% transmission rate as the null hypothesis (low dose group). In order for HCQ 
to be considered effective our alternative hypothesis will be a 1% transmission rate. With a 1:1 randomization 
for the HCQ to control arms we would require a total of 350 health care workers across all participating 
ProHealth NY and AHN sites.  With the placebo group of 175 participants and the high dose HCQ arm of 
175 participants, a one-sided z-test (alpha=0.05) comparing the rates in the two groups would have an at least 
80% power to detect a significant difference when the difference in the population rates is at least 9%.  
 
The hypothesis will be tested using a one-sided test, with a z-score corresponds to the log of the odds-ratio 
for the rate of transmission between the two groups. We will obtain the estimate of the odds ratio, and 95% 
CI, from logistic regression.

Drug Classes 
Protocol Language 
Anticonvulsant  
• 
(Exclude) Patients receiving cytochrome P450 enzyme-inducing anticonvulsant drugs (i.e. phenytoin, 
carbamazepine, Phenobarbital, primidone or oxcarbazepine) within 4 weeks of the start of the study 
treatment   
 
• 
Acceptable drug alternatives include:  Because HCQ has known effects on P450 enzymes, patients 
requiring anti-convulsants may be treated with any of the non-enzyme inducing anti-convulsants 
which include: felbamate, valproic acid, gabapentin, lamotrigine, tiagibine, topiramate, or 
levetiracetam. Due to the fact that both zonisamide and HCQ accumulate in red blood cells, 
zonisamide should be avoided if possible. All other concomitant medications are permitted. 
 
Antiviral 
• 
(Exclude) Any investigational or off-label antiviral therapy   
• 
(Include)  Patients with HIV may participate   
• 
(Include)  Patients with herpes may participate 
Cancer Treatments 
• 
(Exclude) Anyone receiving active cancer treatments.   
• 
(Exclude) Any concurrent chemotherapy, radiotherapy (except radiotherapy as designated in this 
study or radiotherapy indicated for CNS metastasis) 
• 
(Exclude) Immunotherapy,

(Exclude) Immunosuppressive medications, including, corticosteroids at doses exceeding 10mg/day of 
prednisone or equivalent, methotrexate, azathioprine, and TNF-alpha blockers.  
• 
(Include) Use of immunosuppressive medication for the management of study treatment related AEs 
or in subjects with contrast allergies is acceptable.  
• 
(Include) In addition, use of topical, inhaled and intranasal corticosteroids is permitted. 
 
Live attenuated 
vaccines 
• 
(Exclude) If using live attenuated vaccines during the study through 180 days after the last dose of 
both drugs.  Examples include: MMR, Zostavax, Polio, Varicella 
• 
(Include) If using non-living vaccines.  Examples include: Flu vaccine, Pneumonia vaccine 
Insulin or 
antidiabetic drugs 
• 
Reduce dosage consideration.  As HCQ may enhance the effects of a hypoglycemic treatment, a 
decrease in doses of insulin or antidiabetic drugs may be required. 
Arrhythmogenic  
• 
Drugs that prolong QT intervals.  
• 
HCQ can prolong the QT interval and should not be administered with other drugs that have the 
potential to induce cardiac arrhythmias.  
• 
Also, there may be an increased risk of inducing ventricular arrhythmias if HCQ is used concomitantly 
with other arrhythmogenic drugs 
 
Antiepileptics 
• 
Side effect.  The activity of antiepileptic drugs might be impaired if co-administered with HCQ.

HCQ vs CQ 
What is the difference 
between the recently 
published study in Brazil and 
There are several key but crucial differences between the recently 
published study in Brazil and the PATCH studies: 
1. The Brazil study involved chloroquine, not hydroxychloroquine. 
Chloroquine is chemically similar to hydroxychloroquine but the

the PATCH studies being 
conducted at ProHEALTH? 
two have very different safety records at high doses with 
hydroxychloroquine being the safer of the two.  
 
2. Participants in the Brazil study were taking two additional 
antibiotics (Ceftriaxone and Azithromycin) which are known to 
exacerbate this problem. 
 
3. Not only is the medication itself different, but so is the dose. The 
daily dose in the Brazil study was very high. 
 
4. The PATCH study populations are different from the Brazil study 
which involved individuals hospitalized for COVID-19, which is 
not the case here.

Drug Classes 
Protocol Language 
Anticonvulsant  
• 
(Exclude) Patients receiving cytochrome P450 enzyme-inducing anticonvulsant drugs (i.e. phenytoin, 
carbamazepine, Phenobarbital, primidone or oxcarbazepine) within 4 weeks of the start of the study 
treatment   
 
• 
Acceptable drug alternatives include:  Because HCQ has known effects on P450 enzymes, patients 
requiring anti-convulsants may be treated with any of the non-enzyme inducing anti-convulsants 
which include: felbamate, valproic acid, gabapentin, lamotrigine, tiagibine, topiramate, or 
levetiracetam. Due to the fact that both zonisamide and HCQ accumulate in red blood cells, 
zonisamide should be avoided if possible. All other concomitant medications are permitted. 
 
Antiviral 
• 
(Exclude) Any investigational or off-label antiviral therapy   
• 
(Include)  Patients with HIV may participate   
• 
(Include)  Patients with herpes may participate 
Cancer Treatments 
• 
(Exclude) Anyone receiving active cancer treatments.   
• 
(Exclude) Any concurrent chemotherapy, radiotherapy (except radiotherapy as designated in this 
study or radiotherapy indicated for CNS metastasis) 
• 
(Exclude) Immunotherapy,  
• 
(Exclude) Biologic or hormonal therapy for cancer treatment, except as noted in the exclusion criteria.  
• 
(Include)  A Cancer survivor receiving no treatments may participate 
• 
(Include)  Concurrent use of hormones for non-cancer-related conditions (e.g. insulin for diabetes, 
hormone replacement therapy). 
Immunosuppressive   • 
(Exclude) Immunosuppressive medications, including, corticosteroids at doses exceeding 10mg/day of 
prednisone or equivalent, methotrexate, azathioprine, and TNF-alpha blockers.  
• 
(Include) Use of immunosuppressive medication for the management of study treatment related AEs 
or in subjects with contrast allergies is acceptable.  
• 
(Include) In addition, use of topical, inhaled and intranasal corticosteroids is permitted. 
 
Live attenuated 
vaccines 
• 
(Exclude) If using live attenuated vaccines during the study through 180 days after the last dose of 
both drugs.  Examples include: MMR, Zostavax, Polio, Varicella 
• 
(Include) If using non-living vaccines.  Examples include: Flu vaccine, Pneumonia vaccine 
Insulin or 
antidiabetic drugs 
• 
Reduce dosage consideration.  As HCQ may enhance the effects of a hypoglycemic treatment, a 
decrease in doses of insulin or antidiabetic drugs may be required. 
Arrhythmogenic  
• 
Drugs that prolong QT intervals.  
• 
HCQ can prolong the QT interval and should not be administered with other drugs that have the 
potential to induce cardiac arrhythmias.  
• 
Also, there may be an increased risk of inducing ventricular arrhythmias if HCQ is used concomitantly 
with other arrhythmogenic drugs

HCQ vs CQ 
What is the difference 
between the recently 
published study in Brazil and 
the PATCH studies being 
conducted at ProHEALTH? 
There are several key but crucial differences between the recently 
published study in Brazil and the PATCH studies: 
5. The Brazil study involved chloroquine, not hydroxychloroquine. 
Chloroquine is chemically similar to hydroxychloroquine but the 
two have very different safety records at high doses with 
hydroxychloroquine being the safer of the two.  
 
6. Participants in the Brazil study were taking two additional 
antibiotics (Ceftriaxone and Azithromycin) which are known to 
exacerbate this problem. 
 
7. Not only is the medication itself different, but so is the dose. The 
daily dose in the Brazil study was very high. 
 
8. The PATCH study populations are different from the Brazil study 
which involved individuals hospitalized for COVID-19, which is 
not the case here.
