Clinical trial NCT04605588
Conditions: SARS-CoV Infection Covid19
Sponsor: Rutgers, The State University of New Jersey
Start date: 2020-12-02; Completion date: 2021-02-04
Enrollment: 7 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
New outpatient treatments for COVID-19 are urgently needed. There is some evidence that a combination of three medications currently used to treat other viral infections could be effective in fighting this new virus. The purpose of this trial is to evaluate the efficacy of Nitazoxanide (NTZ), Ribavirin (RBV) and Hydroxychloroquine (HCQ) versus placebo in participants with proven SARS-CoV-2 infection

The study will enroll 70 participants within the 7 days after having been diagnosed with coronavirus infection. The purpose is to determine if those randomized to 5-day dosing with the three medication combination have decreased viral load and severity of illness in the 10 days following treatment as compared to those taking placebo. Participants will be actively followed for 28 days.

Detailed description:
Participants will be randomized into one of two treatment plans

* Triple combination:

  * Nitazoxanide (500 mg po BID for day 1and then 500 mg BID for 4 days)
  * Ribavirin (600 mg po BID for day 1and then 400 mg BID for 4 days)
  * Hydroxychloroquine sulfate (400 mg po BID for day 1 and then 200 mg BID for 4 days)
* No active Medication:

  * Placebo administered according to the above schedule

Viral load (qPCR via nasal swab) will be assessed at baseline (day 0) as well as at days 3, 6, and 10 to monitor response to antiviral treatment. Immune status will be determined by antibody testing of blood collected at baseline and day 28. Symptom questionnaires will be completed daily for 10 days and day 28.

Arms: arm 1: 5 day dosing of Nitazoxanide, Ribavirin \& Hydroxychloroquine sulfate arm 2: 5 day dosing of placebo
Interventions: intervention 1: Nitazoxanide intervention 2: Placebo Nitazoxanide intervention 3: Ribavirin intervention 4: Placebo Ribavirin intervention 5: Hydroxychloroquine intervention 6: Placebo Hydroxychloroquine
Intervention descriptions: intervention 1: Nitazoxanide (500 mg po BID for day 1and then 500 mg BID for 4 days) intervention 2: Placebo Nitazoxanide (500 mg po BID for day 1and then 500 mg BID for 4 days) intervention 3: Ribavirin (600 mg po BID for day 1and then 400 mg BID for 4 days) intervention 4: Placebo Ribavirin (600 mg po BID for day 1and then 400 mg BID for 4 days) intervention 5: Hydroxychloroquine sulfate (400 mg po BID for day 1 and then 200 mg BID for 4 days) intervention 6: Placebo Hydroxychloroquine sulfate (400 mg po BID for day 1 and then 200 mg BID for 4 days)

1.1 Purpose/Specific Aims 
The purpose of this study is to evaluate the efficacy of Nitazoxanide (NTZ), Ribavirin (RBV) and 
Hydroxychloroquine (HCQ) versus placebo in participants with proven SARS-CoV-2 infection who are 
asymptomatic or mildly symptomatic with COVID-19. Those with illness requiring hospitalization, or 
who present with hypoxia (PO2<92%) or shortness of breath at time of enrollment are excluded. 
 
A.  Objectives  
 
In participants with proven SARS-CoV-2 infection who are asymptomatic or mildly symptomatic with 
COVID-19 randomly allocated to nitazoxanide, ribavirin plus hydroxychloroquine (NTZ, RBV + HCQ) 
or placebo. 
 
Primary Objective: 
To assess the rate of decline in viral load over the 10 days after randomization between participants 
treated with NTZ, RBV + HCQ for COVID-19 and placebo. 
 
Secondary Objective: 
1. To compare the proportion of participants with virus below LLOQ at day 10  
2. To compare the proportion of participants who are asymptomatic and symptomatic at day 
10  
3. To compare the time of onset and frequency of the development of fever and other 
symptoms of COVID-19 in those who were asymptomatic at enrollment 
4. To compare the progression in severity of COVID-19 symptoms (hospitalization and length 
of stay; admission to intensive care unit and number of days in unit; intubation, Death (any 
cause))   
5. To compare the severity of disease in participants who develop symptoms of COVID-19  
6. To compare the side effects of NTZ, RBV + HCQ compared to placebo 
7. To determine whether baseline viral load predicts response to therapy 
8. To assess the rate of decline in viral load over days 3 and 6 after randomization 
9. To assess new, self-reported COVID-19 infection in household members 
 
B. Hypotheses / Research Question(s) 
We hypothesize that treatment with NTZ, RBV + HCQ decreases viral load and the progression of 
symptoms, or emergence of symptoms in those who are asymptomatic at baseline, in SARS-CoV-
2-positive adults compared to placebo. 
 
1.2 Research Significance 
 
From its origins in late 2019 at a wet seafood market in Wuhan, China, infection with severe acute 
respiratory syndrome coronavirus-2 (SARS-CoV-2) has rapidly become a global pandemic 1. The clinical 
manifestations of coronavirus disease-2019 (COVID-19) range from asymptomatic carriage and mild upper 
respiratory symptoms to severe pneumonia, respiratory failure, sepsis, and death 2. Viral transmission 
appears to occur predominantly via inhalation or by contact with infectious droplets 3. In addition to spread 
from symptomatic persons, pre-symptomatic and asymptomatic hosts also can transmit SARS-CoV-2, 
complicating efforts to contain its spread 4.  
 
Since the virus is novel in humans and pre-existing immunity appears to be lacking, estimates of its spread 
are guided by previous pandemics of new influenza strains that could infect 50-70% of the world population 
within 2 years 5. SARS-CoV-2 is highly infectious, with estimated R0 between 2 and 4, and  doubling in 
many countries about every 4 days 6. The U.S has experienced similar exponential spread, and despite 
community efforts to encourage social distancing through school and event cancellations, remote 
workplaces, and self-quarantining, many experts predict that the U.S. health care system, like those in parts

of Europe and Asia, will soon be overwhelmed with new cases, with hospitals and healthcare workers 
(HCW) facing unprecedented challenges 7, 8 
  
A triple combination antiviral coronavirus therapy (TriACT) comprised of hydroxychloroquine sulfate, 
ribavirin, and nitazoxanide for the treatment of acute illness due to SARS-CoV-2 infection is being tested 
in the study.  Each of these drugs is currently available as oral drug product approved for marketing in 
many of the major world markets.  In the US, they are available under the trade names, PLAQUENIL® 
(hydroxychloroquine sulfate, USP) tablets, for oral use;  Rebetol® (ribavirin, USP) capsules and oral 
solution, for oral use; or Alinia® (nitazoxanide) tablets, for oral use. 
 
The pharmacological rationale for the treatment of SARS-CoV-2 with a triple combination antiviral therapy 
is based on two distinct rationales:  i) high antiviral potency through synergy, in order to block viral 
replication, and ii) creating a high genetich barrier to antiviral drug resistance.  It was previously 
discovered that by carefully selecting drugs that block sequential steps in viral replication could lead to 
synergy, or a multiplicative increase in antiviral potency.  The triple combination therapy of amantadine, 
ribavirin and oseltamivir was shown to be 20-fold synergistic, in both in vitro models and in vivo models.9 
This product was evaluated in a global Phase 2 clinical trial conducted by NIH/NIAID, which showed that 
this three- antiviral drug combination significantly reduced viral load compared to oseltamivir alone.10 
The in vitro pharmacology of hydroxychloroquine sulfate, ribavirin, and nitazoxanide has been examined 
in SARS-CoV-2 and related viral infections, and have all demonstrated promising, yet modest effects, on 
slowing viral replication in vitro and in vivo.  These drugs sequentially block steps in the SARS-CoV-2 viral 
replication life cycle, including uncoating, replication and reassembly of virus particles in the host human 
cells.  Each of these drugs exhibit effective antiviral concentrations (or EC50s) ~1 µg/ml based upon in 
vitro data in corona virus infected cell lines that approximate the blood concentration ranges of their 
respective labels:   
 
 
Hydroxychloroquine:   
0.24 to 2.4 µg/ml 11,12   
 
Ribavirin: 
 
 
4 to 8 µg/ml 13 
 
Nitazoxanide:   
 
0.3 to 1 µg/ml 14  
 
In addition to the direct antiviral activity of the triple combination each of the individual drugs has 
documented immunomodulatory activities that may contribute to the overall impact on the host.15-17  
Combining drugs with both direct antiviral and immunomodulating activity is a rational approach based on 
the pathophysiology of the infection where immune dysregulation and hyperinflammatory responses 
contribute to multi-organ dysfunction and death(cytokine storm).   
 
The clinical efficacy, safety, and pharmacokinetics of orally administered hydroxychloroquine sulfate, 
ribavirin, and nitazoxanide have been investigated as monotherapies in SARS-CoV-2 and related 
infections.   
 
Hydroxychloroquine has been widely studied in clinical trials for coronaviruses, including COVID19.  In a 
randomized controlled trial (RCT) comparing HCQ (n = 31) versus no HCQ (n = 31) in mild to common 
COVID-19 (NHC criteria) patients, Chen et al. reported that the HCQ group had shorter time to clinical 
recovery and radiologic improvement in pneumonia.18  A non-randomized case-control study in France, 
which compared HCQ (n = 14) and HCQ plus azithromycin for prevention of bacterial superinfection (n = 
6) against a control group (n = 16). At day 6 of treatment, all patients in the HCQ plus azithromycin group 
tested virus-free, compared to 57.1% in the HCQ-alone group and 12.5% of the control group (P 
<0.001).19 Other studies have shown less favorable results. A small non-blinded RCT in China comparing 
HCQ (n = 15) against a control group (n = 15) in patients with common COVID-19 (NHC criteria) showed 
that following 7 days of treatment, throat swabs were negative for the virus in 86.7% of the HCQ group 
compared to 93.3% of the control group (P > 0.05).20 The mean duration from hospitalization to viral 
clearance was comparable in both groups. Results of combination therapy from a retrospective cohort 
study of 368 males from the US Veterans Health Administration medical centers who received either

HCQ, HCQ plus azithromycin or no HCQ for COVID-19 of varying severities showed that the risk of death 
from any cause was higher in the HCQ group (adjusted hazard ratio (HR) = 2.61; 95% CI: 1.10–6.17; P = 
0.03) compared to the no-HCQ group.21 The risk of ventilation was no different in patients who did not 
receive HCQ compared to those who received HCQ alone (adjusted HR, 1.43; 95% CI: 0.53–3.79; P = 
0.48) or with azithromycin (adjusted HR = 0.43; 95% CI: 0.16–1.12; P = 0.09). The risk of death after 
ventilation also was not significantly different across the 3 groups. 
 
The safety of HCQ in Covid patients has been examined in multiple studies of varying rigor. HCQ use, 
with or without azithromycin among patients hospitalized with COVID-19 in retrospective cohort study of 
1438 patients hospitalized in metropolitan New York, treatment with HCQ, azithromycin, or both was not 
associated with significantly lower in-hospital mortality.22  In another study in New York City, Investigators 
analyzed 1,376 COVID-19 patients who had been admitted to the hospital , including 811 who received a 
5-day course of HCQ.23 The time-to-event analysis found no greater—or lower—risk of intubation or 
death with hydroxychloroquine recipients vs. nonrecipients. Three studies have investigated the use of 
HCQ in severe COVID-19 patients that have reported prolongation of QT intervals.  In a prospective case 
series of 11 severe COVID-19 patients treated with HCQ plus azithromycin, 1 patient discontinued 
treatment due to prolonged QT interval.24 In a cohort study of 181 patients with severe COVID-19 within 
48 hours of admission, 8 (9.5%) of 84 patients in the HCQ group discontinued HCQ after 4 days due to 
prolonged QT interval or first-degree atrioventicular block.25  Perinel et al. examined HCQ dosing in 
severe to critically ill COVID-19 patients by studying the pharmacokinetic properties of HCQ in 13 COVID-
19 ICU patients. In the study, HCQ was withdrawn in 2 (15.4%) patients due to prolonged QT intervals.26 
 
Spontaneous reports to pharmacovigilance centers and drug manufacturers provide an additional 
important source of information that can be used to detect rare adverse events. A summary from the 
WHO Global Database of Individual Case Safety Reports listed a total of 40 cases of sudden death 
and/or death as an outcome of TdP/QT interval prolongation following any antimalarial treatment, all of 
which originated in Europe and North America.27 In 22 cases, the antimalarial was used for an indication 
other than malaria, with drug dosages and durations varying accordingly. In 16 cases, concomitant use of 
another medicine that could potentially increase the risk of QT/QTc interval prolongation was reported. 
Quinidine was the suspected antimalarial in 16 cases; in 12 of these cases, there was evidence of a 
cardiac-related indication and/or concomitant medications, suggesting quinidine was used as an 
antiarrhythmic. Exposure to chloroquine and hydroxychloroquine was reported in six and five cases of 
sudden death, respectively. In four of these cases, overdose was listed as the indication. 
Hydroxychloroquine was used to treat rheumatoid arthritis, systemic lupus erythematosus and small cell 
lung carcinoma in one case each.  
 
The clinical efficacy of ribavirin has been reported in small research studies on the treatment of 
coronaviruses during the SARS‐CoV outbreaks in China and North America, and MERS‐CoV outbreaks 
in the Middle East and Asia. No clinical study has documented a therapeutic benefit of ribavirin 
monotherapy for treatment of corona virus infections. Results from a retrospective cohort study of the 
combination of oral ribavirin with interferon alpha significantly improved survival and in the first reported 
case of MERS-COV in south Korea lead to successful recovery after early treatment.28,29 In a published 
case report, triple therapy with Lopinavir/ritonavir, interferon alpha and oral ribavirin in a patient with 
MERS-CoV infection led to virologic clearance after 6 days of treatment and a full recovery at day 13.30  In 
a prospective, open-label, randomized, phase 2 trial in adults with COVID-19 who were admitted to six 
hospitals in Hong Kong, patients were randomly assigned to a 14-day combination of lopinavir 400 mg 
and ritonavir 100 mg every 12 h, ribavirin 400 mg every 12 h, and three doses of 8 million international 
units of interferon beta-1b on alternate days (combination group) or to 14 days of lopinavir 400 mg and 
ritonavir 100 mg every 12 h (control group).31 Results showed that triple antiviral therapy was safe and 
superior to lopinavir–ritonavir alone in alleviating symptoms and shortening the duration of viral shedding 
and hospital stay in patients with mild to moderate COVID-19.  Finally, a large phase 2 study was 
conducted in influenza patients examining triple combination antiviral drug (TCAD) regimen composed of 
ribavirin, amantadine, and oseltamivir versus oseltamivir monotherapy with matching placebo. A

significant decrease in viral shedding was observed at day 3 relative to monotherapy, however the 
difference was not associated with improved clinical benefit.10  
 
Hemolytic anemia is a common dose-dependent side effect that frequently complicates prolonged use of 
ribavirin for treatment of HCV. Two studies have confirmed similar decreases in hemoglobin level that 
were linearly related to steady-state plasma concentrations of ribavirin and that hemoglobin levels of<8.5 
g/dL occurred when the steady-state ribavirin concentration increased above 3.5 mg/mL.32,33   However, in 
short courses of treatment for influenza and COVID-19 mentioned above, no significant decrease was 
reported.10,31 
 
Nitazoxanide, in addition to antiparasitic activity, has broad-spectrum in vitro antiviral activity against 
influenza, RSV, norovirus, rotavirus, and hepatitis B and C viruses and has shown In vitro activity against 
MERS-CoV and other corona viruses.14 Clinical results for treatment of viral infections have been mixed. 
In one phase 2b/3 clinical trial, oral administration of nitazoxanide 600 mg twice daily for five days 
reduced the duration of clinical symptoms and reduced viral shedding compared to placebo in patients 
with influenza.34  However, in a phase 2 study of nitazoxanide + SOC in patients with severe acute 
respiratory illness (SARI), nitazoxanide did not reduce the duration of hospital stay, supplemental oxygen 
use, or shedding of respiratory viruses on day 3 in patients with SARI.35 
 
Nitazoxanide is generally well tolerated.  In the study by Haffizulla et al., adverse events were similar 
between groups, the most common being headache reported by 24 (11%) of 212 patients enrolled in 
placebo group, 12 (6%) of 201 patients in the nitazoxanide low-dose group, and 17 (8%) of 211 patients 
in the nitazoxanide high-dose group, or diarrhea, reported by seven (3%) patients in the placebo 
group, four (2%) patients enrolled in the nitazoxanide low-dose group, and 17 (8%) patients in the 
nitazoxanide high-dose group.34   Similar safety and tolerability was seen in the study by Gamiño-Arroyo et 
al which reported the similar frequency of adverse events between nitazoxanide and placebo, the most 
common being gastrointestinal disorders (31.9%), infections and infestations (16.3%) and respiratory and 
thoracic disorders (16.3%).35 
 
The pharmacokinetics of hydroxychloroquine, ribavirin, and nitazoxanide are summarized below.  
 
Following a 200 mg oral dose, hydroxychloroquine reached a Cmax of 129.6ng/mL with a Tmax of 3.26h 
in the blood and a Cmax of 50.3ng/mL with a Tmax of 3.74h in the plasma.  Oral hydroxychloroquine has 
an absorption half-life of 3-4 hours.  A 200 mg oral dose of hydroxychloroquine has a half-life of 537 
hours or 22.4 days in blood, and 2963 hours or 123.5 days in plasma.  Steady state modelling of steady 
state dosing of HCQ has been carried out, showing that a 400 mg BID loading dose, followed by 200 mg 
BID for 5 days results in the unbound Css of 600 ng/ml, with lung concentrations >10,000 ng/ml 11(Smith 
et al 2020, data on file). Based on a clinical study, hydroxychloroquine is a weak-to-moderate inhibitor of 
CYP2D6 (causing about a 65% increase in exposure of metoprolol).   
 
After oral ingestion of ribavirin, the plasma concentration exhibits a characteristic three-phase profile, 
consisting of two rapid phases (absorption and distribution) and one long terminal elimination phase. 
Ribavirin is promptly absorbed into circulation, with the help of gastrointestinal, sodium-dependent 
nucleoside transporters in the proximal small bowel. The average time to reach Cmax is 2 hours after oral 
administration of 1200 mg ribavirin. Following administration of 1200 mg/day with food for 12 weeks 
mean±SD (n=39; body weight greater than 75 kg) AUC was 25,361±7110 ng·hr/mL and C was 2748±818 
ng/mL. The terminal half-life of ribavirin following administration of a single oral dose of ribavirin is about 
120 to 170 hours. The total apparent clearance following administration of a single oral dose of ribavirin is 
about 26 L/h.  After 5 days of dosing, Ribavirin levels approaching 3000 ng/ml are achieved with 600 mg 
BID dosing (Wu, et al, 2018).  Ribavirin is eliminated by metabolism and renal elimination, with the latter 
accounting for about 5–15% of single dose elimination.

The active metabolite of NTZ is tizoxanide (desacetyl-nitazoxanide). The initial reaction in the metabolic 
pathway of Nitazoxanide is hydrolysis to tizoxanide, followed by conjugation, primarily by glucuronidation 
to tizoxanide glucuronide.  Following a 500mg oral dose, tizaxoadnide reached a Cmax of 10600 ng/mL 
with a Tmax of 3 h in the plasma.  When administered with food, the AUC of tizoxanide and tizoxanide 
glucuronide in plasma is increased to almost two-fold and the maximum concentration is increased by 
almost 50% compared to when ingested without food.  Following oral administration of a single 
nitazoxanide tablet every 12 hours for 7 consecutive days, there was no significant accumulation of 
nitazoxanide metabolites tizoxanide or tizoxanide glucuronide detected in plasma. 
 
In summary, there do not appear to be overlapping or synergistic toxicities among the drugs.  It is not 
expected that co-administration of these drugs will result in increased safety concerns compared to the 
drugs given individually.  Pharmacokinetic interactions are also not expected to occur, given that each is 
cleared via differing mechanisms.  The use of TriACT has not been investigated in clinical studies to date.   
 
 
1.3 Research Design and Methods 
 
We will conduct a randomized clinical trial enrolling eligible participants who are determined to be SARS-
CoV-2-positive (e.g., via Rutgers Corona Cohort [RCC] study, hospital or other screening programs) who 
volunteer for the study. Specifically, we will enroll 70 participants whose test has been performed within 
the past 7 days who are either asymptomatic or mildly symptomatic at baseline. Mild COVID-19 
symptoms include new cough, sore throat, fever, myalgias, new vomiting or diarrheaor change in smell or 
taste. Illness requiring hospitalization, or those who present with hypoxia (PO2<92%) or shortness of 
breath at time of enrollment will be classified as significantly symptomatic and excluded from study 
participation. People who are allergic or intolerant to NTZ, RBV or HCQ will be excluded. We will 
randomly allocate participants stratified by presence of mild symptoms to 1) NTZ, RBV and HCQ or 2) 
placebo. Treatment with the investigational agents or placebo will continue for 5 days. Viral load will be 
assessed at baseline (day 0) as well as at days 3, 6, and 10 to monitor response to antiviral treatment. 
Immune status will be determined by antibody testing of blood collected at baseline and day 28.  An 
online symptom questionnaire will be completed daily for 10 days and day 28. 
 
Prior to initiating enrollment, we will prepare two randomization tables for treatment assignment using 
permuted blocks of six which will be provided to the research pharmacist. One table will be used for 
participants without symptoms and the other will be used for those with mild symptoms.  The pharmacist 
will prepare kits containing the 5-day supply of study medications (investigational drugs/placebo) which 
will be sequentially numbered in accordance with the randomization tables.  The contents of each kit 
(investigation drugs/placebo) will be indistinguishable.  Study staff will establish symptom status at the 
baseline visit, and per pharmacy order, provide the participant the next numbered medication kit in the 
participant’s stratum (no symptoms/mild symptoms).  The study investigators, staff interacting with the 
participants and the participants are all masked to treatment assignment

2. Treatment Plan: 
 
 
Dosage and Administration 
   Arm 1: NTZ 1000 mg (2 x 250  mg tablets BID for day one) and then  
 1000 mg (2 x 250 mg tablets BID for 4  days) 
 RBV 1200 mg (3 x 200 mg capsules BID day one) and then  
 RBV 800 mg (2 x 200mg capsules BID for 4 days) 
 HCQ 800 mg (2 x 200 mg tablets bid day one) and then 
 HCQ 400 mg (1 x 200 mg tablet BID for 4 days)               
 
Arm 2: Placebo for NTZ (2 tablets BID for day one and then 2 tablets BID for 4 days) 
Placebo for RBV (3 capsules BID day one and then 2 capsules BID for 4 days) 
Placebo for HCQ (2 tablets bid day one and then 1 tablet BID for 4 days) 
 
 
 
Hydroxychloroquine sulfate (HCQ) 
One hydroxychloroquine sulfate tablet contains 200 mg of hydroxychloroquine sulfate, 
which is the equivalent to 155 mg base. 
 
Ribavirin (RBV) 
One ribavirin capsule contains 200 mg of ribavirin. 
 
Nitazoxanide (NTZ) 
One nitazoxanide tablet contains 500 mg of nitazoxanide. 
 
Take all tablets/capsules with a meal or a glass of milk. 
 
All study drugs should be stored at room temperature 20°-25° (68°-77 °F). 
 
 
Concomitant Medications & Supportive Guidelines 
Study participants can receive full supportive care therapies concomitantly during the study. We 
will advise rest, fluids, hot/ showers/baths. We will recommend NO antipyretics since they make 
infections worse by interfering with the generation of fever--which is considered beneficial until it 
reaches 102 degrees F. 
 
B. Participant Enrollment 
We will identify asymptomatic or mildly symptomatic participants who test positive for SARS-CoV-
2 from the Rutgers Coronavirus Cohort (RCC) and hospital screening programs, or from the 
community through advertisements at our medical center, university, and in local publications.  The 
recruiting materials will direct the potential participants to online materials that include information 
about the trial, consent forms, and a screener questionnaire to assess eligibility. If eligible for the 
trial, we will answer any questions and provide as much time as needed to review all study 
materials. The participant may then electronically sign the consent or, as an alternative, wait until 
the initial visit to re-review and sign the consent.  The consenting process will be primarily 
performed remotely to protect research personnel.  
 
As soon as possible after consent, the participant will participate in an in person visit for baseline 
biospecimen collection. On arrival, research staff wearing PPE will re-review the consent, 
confirm/obtain signatures, measure the PO2, do a urine pregnancy test in women with potential to 
be pregnant and measure the baseline QTc interval with the Kardia Mobile 6L (AliveCor, Inc).  A 6 
lead EKG is obtained when the patient places their fingers on 2 electrode sensors while holding 


 
 
 
Protocol Title:  A Triple Combination Antiviral Coronavirus Therapy 
(TriACT) RCT

the device on their leg. The ECG is uploaded to an iPhone and the tracing is sent to the 
Electrophysiologist cardiologist who will calculate the QT and QTc. The device is approved by the 
FDA for QTc measurements.   The participant will be excluded if the Q-T interval is prolonged 
beyond 450 Msec. We will also exclude anyone who has a PO2<92% or a positive pregnancy test.  
We will randomly allocate the participant, provide the assigned medications, and obtain mid-
turbinate self nasal swab and blood samples. We will also take the participant’s temperature and 
pulse.  We will provide education to the patient on how to complete all at-home study procedures 
and use all ancillary study supplies which we will provide (self nasal swab specimen kits, 
thermometer, and pulse oximeter). 
 
We will telephone the participant about 2 hours after the initial medication dose to confirm that the 
Zio AT patch has been triggered for the one-time 2 hour reading (see the Risks of Harm/Potential 
for Benefits to Subjects to Subjects section, page 35), review the BID dosing schedule, study 
procedures, and any participant questions. We will also call on days 3, 6, and 10 for procedure 
review and to confirm self- specimen collection and AE review. We will have an in person visit on 
day 14 to collect a blood specimen and on day 28 to collect a blood specimen and urine 
pregnancy test, review medical status and AEs  Self collection of mid-turbinate nasal swab to 
measure viral shedding will be on days 3, 6 and10 post randomization.  
 
QT interval will be measured on an ongoing basis through day 10 via the Zio AT mobile cardiac 
telemetry device describe in section 4.7 E.  If the corrected QT - QTc interval increases from 
baseline of > 60msec or QT > 500 msec, the medications, if still being taken, will discontinued at 
that time. Participant QTc intervals will be monitored every 6 hours until the interval returns to 
baseline. If a serous arrhythmia is detected during the continuous monitoring, the study 
cardiologist and participant will be promptly contacted, and the participant will be directed to seek 
medical treatment as appropriate.    
 
 
C. Study Safety Assessments 
The Principal Investigator is responsible for ensuring that all staff involved in the study are familiar 
with the content of this section. 
 
1. Definitions: 
 
Adverse Events: 
An adverse event is the development of an undesirable medical condition or the 
deterioration of a pre-existing medical condition following or during exposure to a 
pharmaceutical product, whether considered causally related to the product. An 
undesirable medical condition can be symptoms (e.g., nausea, chest pain), signs (e.g., 
tachycardia, enlarged liver), or the abnormal results of an investigation (e.g., laboratory 
findings, electrocardiogram). In clinical studies, an AE can include an undesirable medical 
condition occurring at any time, including run-in or washout periods, even if no study 
treatment has been administered. The term AE is used to include both serious and non-
serious AEs. 
 
 
Serious Adverse Events: 
A serious adverse event is an AE occurring during any study phase (i.e., screening, run-
in, treatment, wash-out, follow-up), at any dose of the study drugs that fulfills one or more 
of the following criteria: 
o 
Results in death 
o 
Is immediately life-threatening 
o 
Requires in-patient hospitalization or prolongation of existing hospitalization  
o 
Results in persistent or significant disability or incapacity  


 
 
 
Protocol Title:  A Triple Combination Antiviral Coronavirus Therapy 
(TriACT) RCT 
Protocol Version Date:  V3.2 8Oct2020 
 
Page 11 of 41 
 
 
 
o 
Is a congenital abnormality or birth defect 
o 
Is an important medical event that may jeopardize the patient or may require medical 
intervention to prevent one of the outcomes listed above. 
o 
The causality of SAEs (their relationship to all study treatment/procedures) will be 
assessed by the investigator(s) and communicated to the FDA via MedWatch form, if 
applicable. 
 
2. Recording of Adverse Events 
Non-serious adverse events and SAEs will be determined from the time the study drug is 
given, throughout the treatment period and up to and including the one month follow-up 
period. All grade 3 or higher AEs will be recorded. Grade 1 – 2 AEs do not need to be 
recorded. After withdrawal from treatment, participants must be followed-up for all existing 
and new AEs for 60 calendar days after the last dose of trial drug and/or until event 
resolution. All new AEs occurring during that period must be recorded (if SAEs, they must be 
reported to Data Safety Monitoring Board (DSMB) and Rutgers IRB as per SOPs.).   
 
All study-related toxicities/ SAEs must be followed until resolution, unless in the Treating 
Investigator’s opinion, the condition is unlikely to resolve due to the patient’s underlying 
disease. 
 
3. Reporting of Serious Adverse Events 
Investigators and other site personnel must inform the DSMB and Rutgers IRB. FDA will be 
informed as required accordance with the reporting obligations of 21 CFR 312.32. It is the 
responsibility of the principal investigator to compile all necessary information and ensure that 
the FDA receives a report according to the FDA reporting requirement timelines. 
 
All SAEs meeting the criteria for expedited reporting will be reported to the Rutgers IRB within 
the mandated time frames. All SAEs within the safety follow-up window (e.g., within 30 days 
after the last dose of study medications) established in the protocol will be reported. 
 
4. Clinical Safety Assessments 
 
Recording of Adverse Events 
Non-serious adverse events and SAEs will be determined from the time the study drug is 
given, throughout the treatment period and up to and including the 28-day follow-up 
period. All grade 3 or higher AEs will be recorded. Grade 1-2 AEs do not need to be 
recorded. After withdrawal from treatment, participants must be followed-up for all 
existing and new AEs for 28 calendar days after the last dose of trial drug and/or until 
event resolution. All new AEs occurring during that period must be recorded (if SAEs, 
they must be reported to the Data Safety Monitoring Committee and Rutgers IRB).   
 
 
Adverse Events Based on Signs and Symptoms 
When collecting AEs, the recording of diagnoses is preferred (when possible) to 
recording a list of signs and symptoms. However, if a diagnosis is known and there are 
other signs or symptoms that are not generally part of the diagnosis, the diagnosis and 
each sign or symptom will be recorded separately. 
 
D. Data Points 
 
Case Report Forms 
Completion of the electronic case report forms (eCRFs) will be done in accordance with the 
instructions outlined in the study specific data capture plan. All eCRFs are considered the primary

There are data supporting the antiviral activity of NTZ, RBV and HCQ as single agents as summarized 
in Section 1.2. There is no previous human experience with this triple combination.   
 
1.5 Sample Size Justification 
      
      Primary outcome:   
 
Rate of decline in viral load. We expect a gradual decay in viral loads (depending on when in the 
infection's natural history participants are enrolled. Participants will be detected as being SARS-CoV-
2-positive by our screen at varying points in the infection (some early, some late).  Based on the 4 
manuscripts with measurements, including Hung et al 31 and Gautret et al 19, we can calculate an 
expected decline rate. One outcome would be a greater than expected fall in viral load in the active 
arms vs the SoC arm (e.g., 0.3 log10 /day greater decline =0.9 log10 in 3 days). 
 
We will compare rate of decline in viral load Arm 1 (NTZ, RBV + HCQ) to Arm 2 (placebo) with the aim 
of determining if the combination of NTZ, RBV + HCQ is superior to placebo.  We plan to enroll 35 
participants in each arm of the trial for a total of 70.  We assume data are collected at baseline and 3, 
6 and 10 days after enrollment.  
 
Power calculations were obtained from simulated data, where: 
 
Baseline log10 VL was generated from uniform (3,9) distribution (i.e., at baseline, people were 
equally likely to have log10 VL anywhere from 3 to 9. This is consistent with Hung et al 31 
 
For the control group, average change per day was set to either -0.3 or -0.4. In Hung et al 31 it 
appears to be about -0.37. 
 
For the treatment group, the average decline per day was greater (steeper) than the control group 
by either 0.2 or 0.3. In Hung et al 31the difference in slopes appears to be about 0.2 
 
Within person SD was set to either 0.5 or 1. 
 
SD of the slope between individuals was set to 0.2.  In Hung et al 31 the within-group IQR of log10 
VL was relatively small, so we do not expect a large amount of variation in slopes between 
participants. 
 
Power was calculated using the following steps: (1) generate 1000 data sets in each scenario; (2) fit 
random slope and intercept models to the simulated data; (3) record the proportion of times that the 
test of the interaction between treatment and slope was rejected.  
 
Results: Power (%) based on a sample size of 30 per group

In all of these scenarios we would have >80% power to detect a difference in the slope between groups.

C18H26ClN3O•H2SO4           Molecular Weight: 433.95 
 
Hydroxychloroquine sulfate tablets, USP contain 200 mg hydroxychloroquine sulfate, 
equivalent to 155 mg base, and are for oral administration. 
 
Pharmacokinetics:  Following a single 200 mg oral dose of hydroxychloroquine sulfate to 
healthy males, the mean peak blood concentration of hydroxychloroquine was 129.6 ng/mL, 
reached in 3.26 hours with a half-life of 537 hours (22.4 days). In the same study, the plasma 
peak concentration was 50.3 ng/mL reached in 3.74 hours with a half-life of 2963 hours 
(123.5 days). Urine hydroxychloroquine levels were still detectable after 3 months with 
approximately 10% of the dose excreted as the parent drug. Results following a single dose 
of a 200 mg tablet versus I.V. infusion (155 mg), demonstrated a half-life of about 40 days 
and a large volume of distribution. 
 
Mechanism of Action: The precise mechanism by which hydroxychloroquine exhibits activity 
against Plasmodium is not known. Hydroxychloroquine, like chloroquine, is a weak base and 
may exert its effect by concentrating in the acid vesicles of the parasite and by inhibiting 
polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA. 
 
Warnings: 
 
Ocular: Irreversible retinal damage has been observed in some patients who had received 
hydroxychloroquine sulfate. Significant risk factors for retinal damage include daily doses of 
hydroxychloroquine sulfate greater than 6.5 mg/kg (5 mg/kg base) of actual body weight, 
durations of use greater than five years, subnormal glomerular filtration, use of some 
concomitant drug products such as tamoxifen citrate and concurrent macular disease. 
 
Cardiac Effects, including Cardiomyopathy and QT prolongation: Post-marketing cases 
of life-threatening and fatal cardiomyopathy have been reported with use of 
hydroxychloroquine sulfate as well as with use of chloroquine. Hydroxychloroquine sulfate 
prolongs the QT interval. Ventricular arrhythmias and torsades de pointes have been 
reported in patients taking hydroxychloroquine sulfate (see OVERDOSAGE). Therefore, 
hydroxychloroquine sulfate should not be administered with other drugs that have the 
potential to prolong the QT interval. 
 
Worsening of psoriasis and porphyria 
 
Proximal Myopathy and Neuropathy 
 
Neuropsychiatric events, including suicidality

Hypoglycemia: Hydroxychloroquine sulfate has been shown to cause severe hypoglycemia 
including loss of consciousness that could be life threatening in patients treated with or 
without antidiabetic medications 
 
General precautions: General: Use with caution in patients with gastrointestinal, 
neurological, or blood disorders, and in those with a sensitivity to quinine. 
 
Hepatic/Renal Disease: Antimalarial compounds should be used with caution in patients 
with hepatic disease or alcoholism or in conjunction with known hepatotoxic drugs. A 
reduction in dosage may be necessary in patients with hepatic or renal disease, as well as in 
those taking medicines known to affect these organs. 
 
Hematologic Effects/Laboratory Tests: Antimalarial compounds should be used with 
caution in patients with hepatic disease or alcoholism or in conjunction with known 
hepatotoxic drugs. Periodic blood cell counts should be performed if patients are given 
prolonged therapy.  
 
Hydroxychloroquine sulfate should be administered with caution in patients having glucose-6-
phosphate dehydrogenase (G-6-PD) deficiency. 
 
Dermatologic Effects: Dermatologic reactions to hydroxychloroquine sulfate may occur and, 
therefore, proper care should be exercised when it is administered to any patient receiving a 
drug with a significant tendency to produce dermatitis. 
 
Drug Interactions (include but not limited to): Digoxin, Insulin or antidiabetic drugs, Drugs 
that prolong QT interval and other arrhythmogenic drugs, Mefloquine and other drugs known 
to lower the convulsive threshold, Antiepileptics, Methotrexate, Cyclosporin, Praziquantel, 
Antacids and kaolin, Cimetidine, Ampicillin. 
 
Availability: FDA approved; commercially available hydroxychloroquine sulfate will be 
supplied free of charge to all patients enrolled.

C8 H12 N4 O5 and the molecular weight is 244.2  
 
Ribavirin, USP is white, crystalline powder. It is freely soluble in water and slightly soluble in dehydrated 
alcohol. Each film-coated ribavirin tablet intended for oral administration contains 200 mg or 400 mg or 
500 mg or 600 mg of ribavirin. In addition, each tablet contains the following inactive ingredients: 
crospovidone, hypromellose, iron oxide red, iron oxide yellow, magnesium stearate, microcrystalline 
cellulose, polyethylene glycol, povidone, silicon dioxide, talc, and titanium dioxide. 
 
Pharmacokinetics 
Multiple dose ribavirin pharmacokinetic data are available for HCV patients who received ribavirin in 
combination with peginterferon alfa-2a. Following administration of 1200 mg/day with food for 12 weeks 
mean±SD (n=39; body weight greater than 75 kg) AUC was 25,361±7110 ng·hr/mL and C was 2748±818 
ng/mL. The average time to reach C was 2 hours. Trough ribavirin plasma concentrations following 12 
weeks of dosing with food were 1662±545 ng/mL in HCV infected patients who received 800 mg/day 
(n=89), and 2112±810 ng/mL in patients who received 1200 mg/day (n=75; body weight greater than 75 
kg). The terminal half-life of ribavirin following administration of a single oral dose of ribavirin is about 120 
to 170 hours. The total apparent clearance following administration of a single oral dose of ribavirin is 
about 26 L/h. There is extensive accumulation of ribavirin after multiple dosing (twice daily) such that the 
C at steady state was four-fold higher than that of a single dose.

Pregnancy: Women who are or may become pregnant. Ribavirin may cause fetal harm when 
administered to a pregnant woman. women who are or may become pregnant. If this drug is used during 
pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the 
potential hazard to the fetus Men whose female partners are pregnant.  
Hemoglobinopathies: Patients with hemoglobinopathies (e.g., thalassemia major or sickle-cell anemia).

In combination with didanosine: Reports of fatal hepatic failure, as well as peripheral neuropathy, 
pancreatitis, and symptomatic hyperlactatemia/lactic acidosis have been reported in clinical trials.  
 
Ribavirin and peginterferon alfa-2a combination therapy is contraindicated in patients with:  
 
Autoimmune hepatitis. 
 
Hepatic decompensation (Child-Pugh score greater than 6; class B and C) in cirrhotic CHC mono infected 
patients before treatment. 
 
Hepatic decompensation (Child-Pugh score greater than or equal to 6) in cirrhotic CHC patients 
coinfected with HIV before treatment. 
 
Warnings: 
 
Significant adverse reactions associated with ribavirin/peginterferon alfa-2a combination therapy 
include severe depression and suicidal ideation, hemolytic anemia, suppression of bone marrow 
function, autoimmune and infectious disorders, ophthalmologic disorders, cerebrovascular disorders, 
pulmonary dysfunction, colitis, pancreatitis, and diabetes. The Peginterferon alfa-2a Package Insert 
should be reviewed in its entirety for additional safety information prior to initiation of combination 
treatment. 
 
Pregnancy 
Ribavirin may cause birth defects and/or death of the exposed fetus. Ribavirin has demonstrated 
significant teratogenic and/or embryocidal effects in all animal species in which adequate studies have 
been conducted. These effects occurred at doses as low as one twentieth of the recommended human 
dose of ribavirin. Ribavirin therapy should not be started unless a report of a negative pregnancy test has 
been obtained immediately prior to planned initiation of therapy.  
 
Anemia 
The primary toxicity of ribavirin is hemolytic anemia, which was observed in approximately 13% of all 
ribavirin/peginterferon alfa-2a- treated participants in clinical trials. Anemia associated with ribavirin 
occurs within 1 to 2 weeks of initiation of therapy. Because the initial drop in hemoglobin may be 
significant, it is advised that hemoglobin or hematocrit be obtained pretreatment and at week 2 and week 
4 of therapy or more frequently if clinically indicated. Patients should then be followed as clinically 
appropriate. Caution should be exercised in initiating treatment in any patient with baseline risk of severe 
anemia (e.g., spherocytosis, history of gastrointestinal bleeding). Fatal and nonfatal myocardial infarctions 
have been reported in patients with anemia caused by ribavirin. Patients should be assessed for 
underlying cardiac disease before initiation of ribavirin therapy. Patients with pre-existing cardiac disease 
should have electrocardiograms administered before treatment and should be appropriately monitored 
during therapy. If there is any deterioration of cardiovascular status, therapy should be suspended or 
discontinued. Because cardiac disease may be worsened by drug-induced anemia, patients with a history 
of significant or unstable cardiac disease should not use ribavirin. 
 
Hepatic Failure 
Chronic hepatitis C (CHC) patients with cirrhosis may be at risk of hepatic decompensation and death 
when treated with alpha interferons, including peginterferon alfa-2a. Cirrhotic CHC patients coinfected 
with HIV receiving highly active antiretroviral therapy (HAART) and interferon alfa-2a with or without 
ribavirin appear to be at increased risk for the development of hepatic decompensation compared to 
patients not receiving HAART.  
 
Hypersensitivity 
Severe acute hypersensitivity reactions (e.g., urticaria, angioedema, bronchoconstriction, and 


 
 
 
Protocol Title:  A Triple Combination Antiviral Coronavirus Therapy 
(TriACT) RCT

anaphylaxis) have been observed during alpha interferon and ribavirin therapy. If such a reaction occurs, 
therapy with peginterferon alfa-2a and ribavirin should be discontinued immediately, and appropriate 
medical therapy instituted. Serious skin reactions including vesiculobullous eruptions, reactions in the 
spectrum of Stevens-Johnson Syndrome (erythema multiforme major) with varying degrees of skin and 
mucosal involvement and exfoliative dermatitis (erythroderma) have been reported in patients receiving 
peginterferon alfa-2a with and without ribavirin. Patients developing signs or symptoms of severe skin 
reactions must discontinue therapy  
 
Pulmonary Disorders 
Dyspnea, pulmonary infiltrates, pneumonitis, pulmonary hypertension, and pneumonia have been 
reported during therapy with ribavirin and interferon. Occasional cases of fatal pneumonia have occurred. 
In addition, sarcoidosis or the exacerbation of sarcoidosis has been reported. If there is evidence of 
pulmonary infiltrates or pulmonary function impairment, patients should be closely monitored and, if 
appropriate, combination ribavirin/peginterferon alfa-2a treatment should be discontinued. 
 
Bone Marrow Suppression 
Pancytopenia (marked decreases in RBCs, neutrophils, and platelets) and bone marrow suppression 
have been reported in the literature to occur within 3 to 7 weeks after the concomitant administration of 
pegylated interferon/ribavirin and azathioprine. In this limited number of patients (n=8), myelotoxicity was 
reversible within 4 to 6 weeks upon withdrawal of both HCV antiviral therapy and concomitant 
azathioprine and did not recur upon reintroduction of either treatment alone. peginterferon alfa-2a, 
ribavirin, and azathioprine should be discontinued for pancytopenia, and pegylated interferon/ribavirin 
should not be re-introduced with concomitant azathioprine. 
 
Pancreatitis 
Ribavirin and peginterferon alfa-2a therapy should be suspended in patients with signs and symptoms of 
pancreatitis and discontinued in patients with confirmed pancreatitis. 
 
Impact on Growth in Pediatric Patients 
During combination therapy for up to 48 weeks with peginterferon alfa-2a plus ribavirin, growth 
inhibition was observed in pediatric participants 5 to 17 years of age. Decreases in weight for age z-score 
and height for age z-score up to 48 weeks of therapy compared with baseline were observed. At 2years 
post-treatment, 16% of pediatric participants were more than 15 percentiles below their baseline weight 
curve and 11% were more than 15 percentiles below their baseline height curve. The available longer 
term data on participants who were followed up to 6 years post-treatment are too limited to determine the 
risk of reduced adult height in some patients [see Clinical Studies Experience

C12 H9 N3 O5 S and the molecular weight is 307.3 
 
Nitazoxanide is a light yellow crystalline powder. It is poorly soluble in ethanol and practically insoluble in 
water. 
 
 ALINIA Tablets contain 500 mg of nitazoxanide and the following inactive ingredients: maize starch, 
pregelatinized corn starch, hydroxypropyl methylcellulose, sucrose, sodium starch glycollate, talc, 
magnesium stearate, soy lecithin, polyvinyl alcohol, xanthan gum, titanium dioxide, D&C Yellow No. 10 
Aluminum Lake, FD&C Yellow No. 6 Aluminum Lake, and FD&C Blue No. 2 Aluminum Lake. 
 
ALINIA for Oral Suspension, when reconstituted with 48 mL of water, produces 60 mL of a 
homogeneous suspension with a pink color that contains 100 mg nitazoxanide per 5 mL and the 
following inactive ingredients: sodium benzoate, sucrose, xanthan gum, microcrystalline cellulose and 
carboxymethylcellulose sodium, anhydrous citric acid, sodium citrate dihydrate, maltodextrin, modified 
food starch, triacetin, FD&C Red No. 40 and artificial strawberry flavoring.  
 
Pharmacokinetics 
Absorption Single Dosing: Following oral administration of ALINIA Tablets or Oral Suspension, the parent 
drug, nitazoxanide, is not detected in plasma.  
 
Multiple dosing: Following oral administration of a single ALINIA Tablet every 12 hours for 7 consecutive 
days, there was no significant accumulation of nitazoxanide metabolites tizoxanide or tizoxanide 
glucuronide detected in plasma.  
 
Bioavailability: ALINIA for Oral Suspension is not bioequivalent to ALINIA Tablets. The relative 
bioavailability of the suspension compared to the tablet was 70%. When ALINIA Tablets are administered 
with food, the AUC of tizoxanide and tizoxanide glucuronide in plasma is increased almost two-fold and 
the Cmax is increased by almost 50%. When ALINIA for Oral Suspension was administered with food, the 
AUC of tizoxanide and tizoxanide glucuronide increased by about 45-50% and the Cmax increased by 
≤10%. 
 
Distribution: In plasma, more than 99% of tizoxanide is bound to proteins.  
Elimination Metabolism: Following oral administration in humans, nitazoxanide is rapidly hydrolyzed to an 
active metabolite, tizoxanide (desacetyl-nitazoxanide). Tizoxanide then undergoes conjugation, primarily 
by glucuronidation.  
 
Excretion: Tizoxanide is excreted in the urine, bile, and feces, and tizoxanide glucuronide is excreted in 
urine and bile. Approximately two-thirds of the oral dose of nitazoxanide is excreted in the feces and one-
third in the urine.

1.9 Data Collection 
 
A. Primary Data Collection 
Data collection will occur at a baseline visit with follow-up data collected over the subsequent 
month as described below.  
 
 
Location: Study site visits (baseline, day 14 & day 28) will take place at the designated 
RWJMS study location at 93 French St, New Brunswick, NJ which is an Institutional Biosafety 
Committee (IBC) approved location to meet with SARS-Cov-2 positive individuals. Consent 
and all questionnaires will be completed electronically online. This questionnaire will include 
items on health and medical history, lifestyle, employment and patient contact, and 
demographics. At baseline, contact information (e-mail/phone) for the participant will be 
collected as well as contact information of 2 individuals who know the participant well who we 
can reach out to in case the participant falls ill.  
 
Follow-up questionnaires will be administered daily for 10 days and on day 28 after entering 
the study. Follow-up questionnaires will include items on symptoms of COVID-19, reactions to 
the study medications and health status of household members since the last questionnaire 
Up to 3 daily automated reminders will be sent to remind participants to complete the surveys. 
In addition, participants will self-report their body temperature, PO2, and pulse daily through 
REDcap, daily for the first 10 days of the study period. Participants will receive automated 
email/text reminders to record this information daily. We will also call on days 3, 6 and 10 to 
confirm self specimen collection, check medical status and study drug dosing (on days 3 & 6) 
and questionnaire completion compliance. On day 14 participants will return for a blood draw 
and to return the ZIO AT monitoring device.  On day 28, participants will return to the clinic for 
a final symptom assessment, a blood draw for immune function and CBC, pregnancy test, if 
applicable and final study drug accountability.   
 
 
Process of Data Collection: All in-person data collection will be overseen by the clinical 
study coordinator team conducting study visits, with questionnaires self-administered by 
participants.  The blood specimens will be collected at the in-person visits (baseline, day 14 & 
28). Participants will be responsible for reporting their own daily temperatures, PO2 and pulse.

Participant Identifiers: Biospecimen and questionnaire data will be coded by study ID. A link 
between study ID and participant name/date of birth will be retained and available to approved 
study staff to link specimens to participants. 
B. Secondary Data Collection  
For participants who develop symptoms or seek clinical care for any medical, and grant 
permission to obtain records, we will access medical records related to their infection and 
subsequent care. We will review hospital records from acute illness resulting from COVID-19 
including discharge summary, imaging, laboratory studies, and treatments. No medical 
records will be reviewed for participants who remain asymptomatic, and no data will be 
abstracted on unrelated conditions or previous health history.   
 
Type of Records: In those developing symptoms, medical records related to the possible 
infection will be abstracted. Relevant fields include diagnoses, lab values, imaging data, 
medications and other interventions, other inpatient care related to the infection, and 
disposition (e.g., discharge, death).  
 
Location: Study staff with authorized access to the RBHS and hospital electronic records will 
access those records directly. Records that are at outside locations or to which the 
researchers do not have authorized access will be requested directly from the facility. At the 
time of consent, each participant will be asked to sign a form authorizing the release of these 
data. 
 
Inclusion/Exclusion: Records will be abstracted from the date of randomization forward until 
the end of the 28-day active follow-up period. Charts will be reviewed by trained clinical study 
coordinators using secure connections.  
 
Data Abstraction Form(s): Each participant will be assigned a unique study identification 
number that will be linked to each completed electronic questionnaire as well as to the collected 
biospecimens. All questionnaires will be administered via and stored in REDCap software 
hosted by Rutgers Robert Wood Johnson Medical School 17.

4.0 Participant Considerations 
 
4.1 Participant Selection and Enrollment Considerations  
 
A. Method to Identify Potential Participants 
 
The study population will consist of those with a known positive test for SARS-CoV-2 who have no or 
mild symptoms of infection.  We anticipate these individuals will be identified due to their participation 
in ongoing (and upcoming) screening programs (e.g., the RCC study, hospital wide screenings, first 
responder screenings). We will develop relationships with these screening programs and, if 
agreeable, the programs will have participants self-identify as interested in volunteering for future 
research.  We will reach out directly to potentially eligible participants identified in this manner.  We 
will determine if they are asymptomatic or mildly symptomatic and, if eligible, offer participation in the 
trial. We will also recruit participants from the general public through advertisements in local press, 
letters to local clinicians, and emails to university staff and faculty. Interested participants will review 
the trial methods and complete the eligibility questionnaire. We will also send an email to employees 
of Robert Wood Johnson University Hospital, University Hospital, and Rutgers University seeking 
volunteers with SARS-CoV-2-positive tests within the past 7 days.   
 
B. Recruitment Details 
 
We will recruit eligible participants from the RCC study or participants identified from the community 
who test positive for SARS-CoV-2.  The recruiting materials will direct the potential participants to online 
materials that include information about the trial, consent forms, and a screening questionnaire to 
assess eligibility.  
 
C. Participant Screening 
 
We will require all volunteers to complete an on-line screening questionnaire which will identify eligible 
participants. Based on the responses to the screening questionnaire, the volunteers will be notified if 
they could be eligible for the study. Eligible participants will be asked to provide their name, e-mail 
address, and phone number so that study staff may follow up with them to further assess their 
willingness to participate in the trial. 
 
The participant will then come to the study location at 93 French in New Brunswick to complete final 
screening for the trial eligibility. P02 will be measured and 6 lead portable electrocardiogram will be 
performed; if PO2<92% or QT interval is QTc interval > 450 mSEC the participant will be excluded. 
Females of childbearing potential will have a urine test to confirm that they are not pregnant.

4.4 Consent Procedures 
 
A.  Consent Process 
 
Location of Consent Process 
Eligible individuals will complete the consent online following discussion with research 
coordinators by telephone. Remote consent will be utilized to protect the safety of the 
research personnel and others. At the baseline visit, the study staff will review the consent 
document and study procedures, answer any remaining questions, confirm the participant’s 
signature, and also sign the consent. 
 
Ongoing Consent  
Participants will undergo intensive follow-up over the 28 day study period, particularly over 
the first days of active treatment. There will not be ongoing written informed consent 
obtained, but study staff will make it clear that participants may ask questions about the 
research or cease their participation at any time.  
 
Individual Roles for Researchers Involved in Consent 
All consent will be done online by participants (see 1.3A for details) or by the NJ ACTS and 
other RBHS clinical research coordinators who conduct the study visits. 
 
Consent Discussion Duration 
It is anticipated that consent will take approximately 30 minutes to complete. However, we 
recognize that in some cases, additional time may be needed to answer questions or address 
concerns with a study team member. We will answer any questions and provide as much 
time as needed to review all study materials. 
 
Coercion or Undue Influence 
Participants self-initiate interest in study participation by completing the online screening 
survey. We will make it clear that participation is voluntary and that electing not to participate 
will not impact clinical care or employment status.  
 
Participant Understanding 
At the time the research coordinators obtain the electronic consent, they will query to the 
participant to be certain they understand they questionnaire completion and specimen 
collection obligations. Similarly, research coordinators will verify the understanding of these 
procedures of participants who completed an online eConsent before proceeding with 
biospecimen collection. 
 
B. Waiver or Alteration of Consent Process  
N/A 
 
C. Documentation of Consent 
 
Documenting Consent 
Prospective participants who are deemed eligible after completing the online screening survey 
may read through the consent form.  Study staff will contact each individual who provides their 
contact information and express interest in participation.  The consent, eligibility and exclusion 
criteria and study procedures will be reviewed, and questions will be answered. The participant 
will may then electronically sign the consent or, as an alternative, wait until the initial visit to re-
review and sign the consent. The consent will be also be signed by the person obtaining 
consent. The signed consent will be stored in the REDCap database. The consenting process 
will be primarily performed remotely to protect research personnel.

4.6 Economic Burden and/or Compensation for Participants 
 
A.  Expenses  
 
The study drugs will be provided at no charge. At the initial visit we will provide each participant 
with a Zio AT mobile cardiac telemetry device. Participants will return the device at their day 28 
visit. Study participants will not be charged for the cost of any research procedures which are 
conducted as part of this study. Participants and/or their insurance carriers (or Charity Care in the 
absence of insurance) will be expected to pay for the standard of care costs related to COVID-19 
treatment and follow-up and for any other medical treatment (e.g., drug reactions) they require. 
 
B. Compensation/Incentives 
  
Participants will receive a ClinCard at the initial study visit, which will be preloaded with money to 
pay for that day’s parking. On the day 14 and 28 day visits, we will add money to that card to cover 
the parking costs on those days as well. 
 
We will add additional money to the card at the final (day 28) study visit (maximum amount $50). 
The amount of they receive will be based on completion of the study tasks: $25 for completing all 
of the self-collected specimens (days 3, 6, & 10) and $25 for completing both the day 24 and day 
28 (final) study visit and returning ZioAT monitoring device.  
 
Participants will also keep the thermometer and the pulse oximeter provided at the initial study visit,

RIBAVIRIN Adverse Events 
 
Significant adverse reactions associated with Ribavirin/peginterferon alfa-2a combination therapy include 
severe depression and suicidal ideation, hemolytic anemia, suppression of bone marrow function, 
autoimmune and infectious disorders, ophthalmologic disorders, cerebrovascular disorders, pulmonary 
dysfunction, colitis, pancreatitis, and diabetes. 
 
Pregnancy 
Ribavirin may cause birth defects and/or death of the exposed fetus. Ribavirin has demonstrated 
significant teratogenic and/or embryocidal effects in all animal species in which adequate studies have 
been conducted. These effects occurred at doses as low as one twentieth of the recommended human 
dose of Ribavirin. 
 


 
 
 
Protocol Title:  A Triple Combination Antiviral Coronavirus Therapy 
(TriACT) RCT 
Protocol Version Date:  V3.2 8Oct2020 
 
Page 32 of 41 
 
 
 
Ribavirin therapy should not be started unless a report of a negative pregnancy test has been obtained 
immediately prior to planned initiation of therapy. Extreme care must be taken to avoid pregnancy in 
female patients and in female partners of male patients. Patients should be instructed to use at least two 
forms of effective contraception during treatment and for 6 months after treatment has been stopped. 
Pregnancy testing should occur monthly during Ribavirin therapy and for 6 months after therapy has 
stopped.  
 
Anemia 
The primary toxicity of Ribavirin is hemolytic anemia, which was observed in approximately 13% of all 
Ribavirin/peginterferon alfa-2a- treated participants in clinical trials. Anemia associated with Ribavirin 
occurs within 1 to 2 weeks of initiation of therapy. Because the initial drop in hemoglobin may be 
significant, it is advised that hemoglobin or hematocrit be obtained pretreatment and at week 2 and week 
4 of therapy or more frequently if clinically indicated. Patients should then be followed as clinically 
appropriate. Caution should be exercised in initiating treatment in any patient with baseline risk of severe 
anemia (e.g., spherocytosis, history of gastrointestinal bleeding)  
 
Fatal and nonfatal myocardial infarctions have been reported in patients with anemia caused by Ribavirin. 
Patients should be assessed for underlying cardiac disease before initiation of Ribavirin therapy. Patients 
with pre-existing cardiac disease should have electrocardiograms administered before treatment and 
should be appropriately monitored during therapy. If there is any deterioration of cardiovascular status, 
therapy should be suspended or Because cardiac disease may be worsened by drug-induced anemia, 
patients with a history of significant or unstable cardiac disease should not use Ribavirin.  
 
Hepatic Failure 
Chronic hepatitis C (CHC) patients with cirrhosis may be at risk of hepatic decompensation and death 
when treated with alpha interferons, including peginterferon alfa-2a. Cirrhotic CHC patients coinfected 
with HIV receiving highly active antiretroviral therapy (HAART) and interferon alfa-2a with or without 
Ribavirin appear to be at increased risk for the development of hepatic decompensation compared to 
patients not receiving HAART. In Study NR15961 among 129 CHC/HIV cirrhotic patients receiving 
HAART, 14 (11%) of these patients across all treatment arms developed hepatic decompensation 
resulting in 6 deaths. All 14 patients were on NRTIs, including stavudine, didanosine, abacavir, 
zidovudine, and lamivudine. These small numbers of patients do not permit discrimination between 
specific NRTIs or the associated risk. During treatment, patients’ clinical status and hepatic function 
should be closely monitored for signs and symptoms of hepatic decompensation. Treatment with 
peginterferon alfa-2a/ Ribavirin should be discontinued immediately in patients with hepatic 
decompensation  
 
Hypersensitivity 
Severe acute hypersensitivity reactions (e.g., urticaria, angioedema, bronchoconstriction, and 
anaphylaxis) have been observed during alpha interferon and Ribavirin therapy. If such a reaction occurs, 
therapy with peginterferon alfa-2a and Ribavirin should be discontinued immediately, and appropriate 
medical therapy instituted. Serious skin reactions including vesiculobullous eruptions, reactions in the 
spectrum of Stevens-Johnson Syndrome (erythema multiforme major) with varying degrees of skin and 
mucosal involvement and exfoliative dermatitis (erythroderma) have been reported in patients receiving 
peginterferon alfa-2a with and without Ribavirin. Patients developing signs or symptoms of severe skin 
reactions must discontinue therapy. 
 
Pulmonary Disorders 
Dyspnea, pulmonary infiltrates, pneumonitis, pulmonary hypertension, and pneumonia have been 
reported during therapy with Ribavirin and interferon. Occasional cases of fatal pneumonia have 
occurred. In addition, sarcoidosis or the exacerbation of sarcoidosis has been reported. If there is 
evidence of pulmonary infiltrates or pulmonary function impairment, patients should be closely monitored 
and, if appropriate, combination Ribavirin/peginterferon alfa-2a treatment should be discontinued.

Bone Marrow Suppression 
Pancytopenia (marked decreases in RBCs, neutrophils, and platelets) and bone marrow suppression 
have been reported in the literature to occur within 3 to 7 weeks after the concomitant administration of 
pegylated interferon/Ribavirin and azathioprine. In this limited number of patients (n=8), myelotoxicity was 
reversible within 4 to 6 weeks upon withdrawal of both HCV antiviral therapy and concomitant 
azathioprine and did not recur upon reintroduction of either treatment alone. peginterferon alfa-2a, 
Ribavirin, and azathioprine should be discontinued for pancytopenia, and pegylated interferon/Ribavirin 
should not be re-introduced with concomitant azathioprine. 
 
Pancreatitis 
Ribavirin and peginterferon alfa-2a therapy should be suspended in patients with signs and symptoms of 
pancreatitis and discontinued in patients with confirmed pancreatitis. 
 
Impact on Growth in Pediatric Patients 
 During combination therapy for up to 48 weeks with peginterferon alfa-2a plus Ribavirin, growth inhibition 
was observed in pediatric participants 5 to 17 years of age. Decreases in weight for age z-score and 
height for age z-score up to 48 weeks of therapy compared with baseline were observed. At 2 years post-
treatment, 16% of pediatric participants were more than 15 percentiles below their baseline weight curve 
and 11% were more than 15 percentiles below their baseline height curve. 
 
The available longer term data on participants who were followed up to 6 years post-treatment are too 
limited to determine the risk of reduced adult height in some patients.  
 
 
 
 
NITAZOXANIDE Adverse Events 
 
Gastrointestinal 
Gastrointestinal side effects have included abdominal pain (6.6% to 7.8%), diarrhea (2.1% to 4.2%), and 
nausea (3%). Side effects occurring in less than 1% of patients have included vomiting, anorexia, 
flatulence, dyspepsia, constipation, dry mouth, and thirst. 
 
The incidence of gastrointestinal side effects may be dose related. Abdominal pain, diarrhea and 
discolored urine occurred more often in participants receiving higher doses (1 gram twice daily). 
 
Nervous system 
Nervous system side effects have included headache (3.1%). Dizziness, somnolence, insomnia, tremor, 
and hypesthesia have been reported by less than 1% of the patients. 
 
Other 
Adverse effects affecting the body as a whole have included asthenia, fever, pain (pelvic/back), flu 
syndrome, earache, and chills in less than 1% of patients. 
 
Metabolic 
Metabolic side effects have included increased creatinine and SGPT in less than 1% of patients. 
 
Dermatologic 
Dermatologic side effects have included pruritus, rash, and sweat in less than 1% of patients. 
 
Ocular 
Ocular side effects have included pale yellow eye discoloration (<1%).

Renal 
Renal side effects have included kidney pain. 
 
 
 
B. Procedures which Risk Harm to Embryo, Fetus, and/or Pregnant Participants 
Women who are pregnant or unwilling to stop breast feeding are excluded from this trial due to 
the absence of data which demonstrates that this therapy changes morbidity or mortality. 
The US FDA labelling for hydroxychloroquine sulcate risk states the following: 
Teratogenic Effects: Human pregnancies resulting in live births have been reported in the 
literature and no increase in the rate of birth defects has been demonstrated. Embryonic deaths 
and malformations of anophthalmia and microphthalmia in the offspring have been reported when 
pregnant rats received large doses of chloroquine.  
 
Nursing Mothers: Caution should be exercised when administering PLAQUENIL to nursing 
women. It has been demonstrated that hydroxychloroquine administered to nursing women is 
excreted in human milk and it is known that infants are extremely sensitive to the toxic effects of 
4-aminoquinolines.” 
 
The US FDA Labelling for ribavirin states the following: may cause birth defects and/or death of 
the exposed fetus. Ribavirin has demonstrated significant teratogenic and/or embryocidal effects 
in all animal species in which adequate studies have been conducted. These effects occurred at 
doses as low as one twentieth of the recommended human dose of Ribavirin. Ribavirin therapy 
should not be started unless a report of a negative pregnancy test has been obtained immediately 
prior to planned initiation of therapy. Extreme care must be taken to avoid pregnancy in female 
patients and in female partners of male patients. 
 
All patients must be made fully aware of the information relating to the potential for reproductive 
toxicity as detailed in the Informed Consent Form. Patients of childbearing potential and their 


 
 
 
Protocol Title:  A Triple Combination Antiviral Coronavirus Therapy 
(TriACT) RCT

Page 35 of 41 
 
 
 
partners, who are sexually active, must agree to the use of two highly effective forms of 
contraception throughout their participation in the study and for 6 months after last dose of study 
drug(s). 
Women of childbearing potential 
Females of childbearing potential should use reliable methods of contraception from the time of 
screening until 6 months after discontinuing study treatment. Acceptable methods of 
contraception include abstinence, tubal ligation, combined oral, transdermal, or intra-vaginal 
hormonal contraceptives, medroxyprogesterone injections (e.g., Depo-Provera), copper-banded 
intra-uterine devices, hormone impregnated intra-uterine systems and vasectomised partners. All 
methods of contraception (except for total abstinence) should be used in combination with the 
use of a condom by their male sexual partner for intercourse. 
 
Males 
Male patients must use a condom during sexual intercourse with all sexual partners including a 
pregnant female partner during the study and for 4 weeks after discontinuing study treatment. 
However, where a sexual partner of a male participant is a woman of childbearing potential who 
is not using effective contraception, men must use a condom during sexual intercourse during 
the; study and for 6 months after discontinuing study treatment. Male patients should avoid 
procreation during the trial and for 6 months after discontinuing study treatment. 
 
C. Risks of Harm to Non-Participants 
When evaluating the patient during the visit, research personnel will wear appropriate personal 
protective equipment (PPE) as recommended by the CDC. This includes the following: 
 
Gown 
 
Gloves 
 
Eye/face protection (i.e., goggles, face shield) 
 
If available, National Institute for Occupational Safety and Health (NIOSH)-certified 
disposable N95 or better respirator. The CDC has stated that surgical (face) masks have 
been determined to be an acceptable alternative to N95 or better respirators, when the 
supply chain of respirators cannot meet the demand so long as procedures that are likely 
to generate respiratory aerosols are not being performed. The use of mid-turbinate nasal 
swabs to collect viral load specimens during this study is not considered an aerosolizing 
procedure. 
 
 
D. Assessment of Social Behavior Considerations 
N/A 
 
E. Minimizing Risks of Harm 
Once participants are started on study drug, monitoring for prolongation of QTc or development of 
polymorphic ventricular tachycardia is required.  The Zio AT (iRhythm Technologies, Inc.) is a 
mobile cardiac telemetry device that allows continuous monitoring of the QTc interval and heart 
rhythm abnormalities. The Zio AT consists of a small transdermal patch that is applied on the 
participant’s upper chest and a gateway device (size of a cell phone) that has to be kept within 10 
feet of the participant.  The ECG signal is transmitted to iRhythm technologies via the internet 
using the gateway.  The participant does not have to change batteries or do anything to the 
device for the 10-day monitoring interval.  We have used this device clinically and participant 
compliance is excellent. The rhythm is monitored continuously for arrhythmias and our EP-
cardiology team will be notified immediately for any run of ventricular tachycardia (VT) greater 
than 4 complexes and other significant arrhythmias (pauses greater than 3 seconds, heart block, 
atrial fibrillation). We are monitoring for any run of VT since we have found that most episodes of 
torsade de pointes VT are preceded by shorter runs of polymorphic VT. The participant can also

Page 36 of 41 
 
 
 
trigger a transmission by pressing a small button on the transdermal patch if they experience any 
cardiac symptoms. We will monitor the QTc with this device. We will obtain a baseline 
transmission at the initial visit after the participant has been deemed to be eligible based on the 
Kardia Mobile 6L QTc measurement. We will ask the participant to do a transmission for QTc 
measurement 2 hours after the first dose of study drug. These will be reviewed and QTc 
measured by our EP cardiology team.  We will then monitor the QTc interval twice a day at two 
predetermined times. This type of monitoring is equivalent to what can be done in the hospital on 
telemetry and in practice may be superior since the protocol will be strictly adhered to and 
measurements made by an electrophysiologist. If QT interval increases from baseline of > 
60msec or QT > 500 msec, the medications, if still being taken, will discontinued at that time. 
Participant QT will be monitored every 6 hours until the interval returns to baseline. If a serous 
arrhythmia is detected during the continuous monitoring, the study cardiologist and participant will 
be promptly contacted, and the participant will be directed to seek medical treatment as 
appropriate. 
 
Hemolytic anemia has been associated with long-term use of ribavirin.  The study participants will 
receive only a 5 day course of medication.  As an added safety measure hemoglobin level will be 
checked at baseline, day 14 and then again at day 28.  A comprehensive metabolic panel will be 
drawn at baseline, day 14, and day 28.

F. Potential Benefits to Participants 
There may be direct benefit to the patient for participation in this study because the study 
participant may receive hydroxychloroquine sulfate ribavirin and nitazoxanide, which are FDA 
approved and have been shown to have potential activity in patients with COVID-19, although this 
does not guarantee that each individual participant will benefit.

6.0 Data Management Plan 
 
6.1 Data Analysis 
 
We will follow intention-to-treat principles and analyze the groups as randomized. A summary table of 
baseline variables will be created with means and standard deviations for continuous variables or 
percentages for categorical variables, all stratified by treatment group.  
 
Primary outcome. We will have repeated measures of log10 VL for each participant. These 
measurements will occur on day 0 (baseline) and at about days 3, 6 and 10. We will fit a linear mixed 
effects model, where log10 VL is the outcome, indicators for treatment group (SoC reference), time, and 
treatment by time interactions are the predictors. The model will include a random slope and intercept, to 
account for within participant correlation. The robust sandwich variance will be used to estimate standard 
errors. Because we are estimating within participant changes over time from randomization, we can 
estimate a treatment effect at any particular day. Our primary hypotheses involve the change over time, 
which we will assess with the treatment by time interaction terms. If participants drop out from the study

before the day 10 visit, we will use all of their preceding data. Linear mixed effects models rely on the 
assumption that missing data are missing at random.  
 
Secondary outcomes. For binary outcomes, such as progression to having symptoms, intubation, death, 
hospitalization, and admission to intensive care unit, we will fit logistic regression models. The covariates 
will include the treatment group indicators. We will report odds ratios and 95% confidence intervals. For 
change variables, such as change in viral shedding or change in Q-T interval, we will fit linear mixed 
effects models (similar to primary outcome). 
 
 
6.2 Data Security 
Data will be entered into electronic case report forms (eCRFs) through REDCap. These eCRFs are 
used to record participant data generated by participant events: including labs, study medication 
administration, or procedures of the protocol. Access to the database is limited to the research staff on 
a need to know basis. Each authorized user accesses the software using his/her Rutgers NetID and 
password. Audit trails are built into the software to track when data entry was started, when the form 
was declared complete, when the form was monitored/queried, amended, and then finalized.  
 
6.3 Data and Safety Monitoring 
 
A. Data/Safety Monitoring Plan 
 
We will convene an independent DSMB comprised of experts in infectious disease, biostatistics, and 
ethics. The DSMB will review the study protocol and provide recommendations. Recruitment will be 
initiated after the DSMB approves the study protocol. 
 
B. Data/Safety Monitoring Board Details 
 
The DSMB will review recruitment, retention, data completeness, protocol deviations, adverse 
events (AEs), severe adverse events (SAEs) and unexpected problems (UPs) when ½ of the 
participants have been enrolled and will provide written recommendations to the PI.  
 
Adverse events will be monitored in following ways: 1) the DSMB will review all reported adverse 
events and monitor the incidence rates after ½ participants are enrolled, 2) the expedited review of 
unexpected SAEs related to the protocol and unanticipated problems (UP). If unexpected safety 
concerns arise from the trial data or from external research or literature, then safety data reporting 
will be expanded and examined on an ad-hoc basis. The investigators will work with the DSMB to 
ensure that the board members have sufficient information to comprehensively monitor patient 
safety throughout the trial. The DSMB may advise early termination of the trial for safety reasons, 
efficacy of the primary outcome or other modifications to the protocol.  
 
6.4 Reporting Results 
 
A. Individual Participants’ Results  
We will provide each participant the results their immune testing at the end of the trial. 
 
B. Aggregate Results 
Aggregate research results will be shared with the study participants. 
  
C. Professional Reporting 
The policies and procedures of Rutgers University’s legal department (see: Investigator’s 
Handbook) will govern publication of the trial. It is expected that the results of this trial will be 
submitted for publication in a timely manner following the conclusion.

CONSENT TO TAKE PART IN A RESEARCH STUDY 
 
 
Title of Study: A Triple Combination Antiviral Coronavirus Therapy (TriACT) RCT Comparing 
Nitazoxanide, Ribavirin and Hydroxychloroquine vs. Placebo   
Principal Investigator: Jeffrey L Carson, MD 
 
 
STUDY SUMMARY: This consent form is part of an informed consent process for a research study 
and it will provide information that will help you decide whether you want to take part in this study.  It is 
your choice to take part or not.  
 
The purpose of the research is to determine whether treating people like you who test positive for 
coronavirus infection (COVID-19) but who do not have symptoms, or who have mild symptoms, will 
reduce the amount of virus and the chances of getting sick. Currently there are no proven treatments 
for COVID-19. There is some evidence that medications currently used to treat other viruses might also 
work against COVID-19, especially if they are used in combination.  If you take part in this study, you 
will be assigned to take the medicine combination being studied or to take pills called placebo that do 
not have any effect. You will be asked to answer questions about yourself and your health. You will self 
swab your nose and allow us to take blood samples, pregnancy test, and electrical tracings of your 
heart (ECG) using a hand held machine. You will have small patch placed on your upper chest that you 
will keep on for 10 days to monitor your heart beat.  Your first visit will take about 35 minutes (15 
minutes to complete a questionnaire and 20 minutes for the medical testing and to be given the study 
medicines that are assigned to you). You will be given supplies to take home including a small device 
that clips to your fingertip to check the oxygen level in your blood, kits to swab your nose, and a 
thermometer. You will take the study medications 2 times a day for the next 5 days. For the next 10 
days you will take your temperature and your fingertip oxygen level and complete a 5 minute 
questionnaire. On days 3, 6 & 10 you will use one of the kits that we have provided to take a swab of 
your nose and ship the specimens to the research laboratory. You will come in for a 10 minute visit on 
day 14 to provide a blood sample and return the ECG monitoring patch.  On day 28 you will complete 
the final 5 minute questionnaire and also come in for a final study visit to provide a blood sample and 
pregnancy test.  
 
Possible harms or burdens of taking part in the study may be discomfort from giving the samples and 
having side effects from the study medications, such as an upset stomach, a skin rash or itching, or an 
irregular heart beat. The possible benefits of taking part may be that taking the study medicines 
decreases how sick you become from the infection.  
 
An alternative to taking part in the research Your alternative to taking part in the research study is 
not to take part in it. 
 
 
The information in this consent form will provide more details about the research study and what will be 
asked of you if you choose to take part in it. If you have any questions now or during the study, if you 
choose to take part, you should feel free to ask them and should expect to be given answers you 
completely understand.  After your questions have been answered and you wish to take part in the

Why is this study being done?  
 
 
The coronavirus disease-2019 (COVID-19) is spreading throughout the United States.  There are no 
proven therapies to treat those who have become sick and what, if any treatment, should be provided is 
unknown. There is some evidence that a combination of three medications currently used to treat other 
viral infections could be effective in fighting this new virus. This combination includes one medication 
currently used to treat diarrhea (nitazoxanide, also known as Alinia), one medication currently used to 
treat severe lung infection and hepatitis (ribavirin, also known as Rebetol), and one medication currently 
used to treat rheumatoid arthritis, lupus, and malaria (Hydroxychloroquine sulfate, also known as 
Plaquenil). 
 
Some people who test positive for the coronavirus infection do not appear to be sick or have mild 
symptoms. We are trying to learn more about the infection in these people within the month after being 
diagnosed. We want to learn if taking the three medication combination might help those with coronavirus 
infection who have not developed serious illness.  
 
This study is to see how much infection (measured in samples taken from nasal swabs) there is at the 
beginning of the study and how much that changes during the study. We also want to see who develops 
new symptoms (for example, a new fever or cough), or if there is any change in mild symptoms. The 
study will see whether there is any benefit to taking these medications.  
 
 
Who may take part in this study and who may not? 
 
You may take part in this study if you are 21 or older and have been tested for coronavirus (Sars-CoV-2) 
within the past 7 days and told that those results were positive and you do not have symptoms requiring 
hospitalization and you are not currently short of breath. 
 
You cannot take part in this study if you have a known reaction to any of the study medications 
(Nitazoxanide, Ribavirin, and Hydroxychloroquine sulfate) or are currently taking these medications, have 
a heart rhythm problem that requires medication, take medicines that might lead to heart rhythm problem, 
or are known to have had serious disturbances to your heart rhythm, or if you have problems in your 
retina (back of your eye). You cannot participate if you are on kidney dialysis, if you have difficulty taking

medications by mouth, or if you are pregnant or nursing, or planning to become pregnant within the next 6 
months. 
 
If you are a female of childbearing potential both you and your partner must agree to the use of two highly 
effective forms of birth control for the 6 months after you enter the study. Acceptable methods of include 
abstinence, tubal ligation, combined oral, transdermal or intra-vaginal hormonal contraceptives, 
medroxyprogesterone injections (e.g., Depo-Provera), copper-banded intra-uterine devices, hormone 
impregnated intra-uterine systems. All methods of contraception should be used in combination with the 
use of a condom by your partner.  
 
If you are a male you must use a condom during sexual intercourse with all sexual partners including a 
pregnant female partner during the study and for 4 weeks after discontinuing study treatment. If your 
partner is not using effective contraception and is of childbearing potential, you must use a condom 
during sexual intercourse during the; study and for 6 months after discontinuing study treatment.  
 
 
Why have I been asked to take part in this study? 
 
You have been notified that your test results show that you have coronavirus infection and you do not 
have symptoms or you have symptoms that do not require hospitalization and you are not short of breath. 
This study is being done to better understand how best to treat the infection in people like you.  
 
 
How long will the study take and how many subjects will take part? 
 
There will be about 70 participants in the study.  From time of enrollment, each participant will be actively 
followed for one month.  It will take one year to complete the study. 
 
 
What will I be asked to do if I take part in this study? 
 
If you take part in this study, you will complete questionnaires.  You will have 3 study visits 1) an initial 
study visit when you are first enrolled, 2) a second visit on day 14, and 3) a final visit at day 28 when the 
study ends.  You will have an ECG and fingertip oxygen level when you enter the study, provide a nose 
swab, and have a blood sample (about 3 teaspoons) of blood taken. You will have a small patch applied 
to your upper chest that you will keep on for 10 days to measure your heart rhythm. You will take the 
study medications that you are given for twice a day for 5 days. You will be given home collection kits to 
swab your nose on days 3, 6 and 10.  These kits also contain packaging materials and postage paid 
labels for you ship your specimens to the study research laboratory on each of the collection days. You 
will also be given a thermometer and a fingertip oxygen measurement device (known as a pulse 
oximeter).  For the first 10 days, you will also take your temperature and your fingertip oxygen level and 
complete questionnaires.  You will return for a study visit on day 14 to provide a blood sample (about 3 
teaspoons) and to return the ECG monitoring device. You will have a blood sample (about 3 teaspoons) 
taken and a pregnancy test at the day 28 (final) study visit.  
 
After your eligibility has been confirmed and you sign this consent form, you will come to the study 
location at the 93 French St, New Brunswick, N.J. If your ECG shows that you are at risk for the study 
medication causing a disturbance to your heart rhythm, or if your fingertip oxygen level is less than 92%, 
you will not be included in the study; your participation will end, and we will suggest you contact your 
healthcare provider.  If you are a female of childbearing age, you will be given a urine pregnancy test to 
confirm that you are not pregnant.

If you continue in the study, the research staff will supervise your self nose swab and draw your blood. 
We will also place a small patch on your upper chest that is to stay in place for the next 10 days.  This 
may require that we shave any hair that could be in the way. You will be able to shower and perform your 
usual activities while the patch is in place. 
 
You will then be assigned by random rules of research (like a coin flip) to receive one of the treatment 
plans being studied.  One treatment plan is the combination of the medicines (Nitazoxanide, Ribavirin, 
and Hydroxychloroquine sulfate) and the other plan is not to receive any real (active) medications. You 
will have an equal chance of being in each of the plans.  Neither you nor the research team will know 
which plan you are in.  The research staff will give you a 5 day supply of pills.  The number of pills and the 
schedule for taking them is the same in each of the plans.  If you are in the plan where you are not taking 
the real medication, the pill that you receive will look the same but it will not have any ingredients that will 
affect you (for example, it may be made of sugar or starch). This pill is called a placebo.  All pills are 
always to be taken by mouth.  The schedule for taking the pills is

The initial questionnaire will capture information about your health history including what diseases and 
conditions you already have, the medications you are currently taking, and what symptoms you are 
currently experiencing. The follow-up questionnaires will ask you to confirm that you have taken the 
required number of study medications, your temperature and fingertip oxygen levels, and will ask about 
your current health and if you have any new symptoms to report. We will keep in touch with you by 
telephone or other secure communication to be sure that you are taking the study medication, collecting 
and shipping your specimens, review study procedures and to answer any questions that might arise.  
 
Your participation will end at the day 28 study visit which will take place at 93 French St, New Brunswick, 
N.J.

Genomics Research Institute (TGen) Phoenix, Arizona, the study research laboratory, where they will be 
analyzed for amount of virus. 
 
Should you develop symptoms from coronavirus disease-2019 (COVID-19) that require medical 
treatment, we would like to request records related to that treatment. If you agree, we will have you sign a 
form that gives the study doctors permission to review all of your medical records related to the infection 
for the month that you are in the study, or until the infection clears. We would not review records 
unrelated to COVID-19 or records from before you entered the study or after you leave the study. 
 
You will also provide your contact information and the names and contact information of 2 individuals who 
know you well to use if you have missed a study activity and we are not able to reach you.

The use of the three study medications (nitazoxanide, ribavirin, and hydroxychloroquine) in combination 
has not been studied.  While there is a possible benefit from using the combination, it is also possible 
there is an increased risk of side effects. 
Risks associated with the questionnaire: We will ask questions pertaining to your health and medical 
conditions that you have.  This information will be secured and used only for the purposed described in 
this consent. 
Risks associated with blood draw: When blood is drawn, there may be a bruise, or bleeding, or 
infection, at the place where the blood is drawn. However, infection is rare. 
Risks associated with nose swab: A nose swab test has few risks. You may also feel slightly 
uncomfortable, but you should not feel any pain. You may have a minor nosebleed afterwards.    
 
Risks associated with ECG: The baseline ECG will be performed with a handle held device by having 
you place both thumbs on the top sensors, and touching the bottom sensor to the bare skin of your left 
leg (knee or ankle). There are no risks. The continuous ECG monitoring is performed using a 2-by-5-inch 
adhesive patch, worn much like a bandage, on the upper left side of the chest. It is water resistant and 
can be kept on around the clock while you sleep, exercise, or take a shower.  
Reproductive Risks: You should not become pregnant or father a baby while on this study because the 
drugs in this study can affect an unborn baby.  Women should not breastfeed a baby while on this 
study.  It is important to understand that you need to use birth control while on this study.  You also must 
avoid getting pregnant for up to 6 months after receiving the last dosing of study drug. Check with your 
study doctor about what kind of birth control methods to use and how long to use them.  Some methods 
might not be approved for use in this study.  If you become pregnant or father a baby within 6 months 
after the last study drug dose, you must inform your study doctor immediately. 
 
Are there any benefits to me if I choose to take part in this study? 
 
If the study finds that one of the treatment plans reduces amount of virus or illness, then the participants 
assigned to that plan may benefit.  However, we do not know if there will be any benefit to taking the 
study medications.  
 
You will be allowed to keep the thermometer and the pulse oximeter. 
 
There is much that is unknown about coronavirus infection.  Your participation in this study will provide 
valuable information towards the development of treatments and strategies to combat the illness and its 
spread. 
 
 
 
What are my alternatives if I do not want to take part in this study? 
 
Your alternative is not to take part in this study and to discuss treatment with your personal physician.. 
 
 
How will I know if new information is learned that may affect whether I am willing to stay in the 
study?

During the study, you will be updated about any new information that may affect whether you are willing 
to continue taking part in the study.  If new information is learned that may affect you after the study or 
your follow-up is completed, you will be contacted. 
 
Will I receive the results of the research? 
 
In general, we will not give you any individual results from the study. If we find something of urgent 
medical importance to you, we will inform you, although we expect that this will be a very rare occurrence.   
 
At the end of the study, we will provide your antibody results from your blood test. 
 
Will there be any cost to me to take Part in this study? 
 
There is no cost to you for participating in this study.  All study medications as well as the Zio Patch 
continuous ECG monitoring will be provided to you free of charge.  Should you require medical attention 
for COVID-19, those costs will be paid by the insurance plan that you are covered by. 
 
 
Will I be paid to take part in this study? 
 
We will provide a ClinCard (which is a specially designed debit card for clinical research) at your initial 
study visit, which will be preloaded with money to pay for that day’s parking.  When you come in for the 
day 14 and 28 day visits, we will add money to that card to cover your parking costs on those days as 
well. 
 
We will also add additional money to the card at the final (day 28) study visit.  That amount  (up to a 
maximum of $50) is based on completion of the study tasks: $25.00 for completion of all of the at home 
nose swabs and $25.00 for completing the day 14 & 28 visits (includes return of the ECG monitoring 
device).   
 
Greenphire, the company which developed the ClinCard, will act as an agent of Rutgers University to 
manage the payment. You will be given a Greenphire ClinCard, which is a debit card that your study 
payments are loaded onto following completion of study visits. When a study visit is completed, the 
payment will be approved and loaded onto your card. The funds will be available within one hour of the 
completed visit, unless the study coordinator advises you that it may take a little longer. You may use the 
ClinCard as you choose. You will be issued one ClinCard for the duration of your study participation. If 
your card is lost or stolen, you can contact ClinCard support at (866) 952-3795. This phone number is 
also on the back of the card. If you do need a replacement card and you obtain it directly through the 
ClinCard customer support service, it will be mailed to your address. In that event, the balance from your 
lost card will be loaded onto your replacement card, minus a $7 replacement fee charged by the customer 
support service. Or, you may request a replacement card during your next visit with your study 
coordinator, who will provide you with a replacement card for a fee of $3.50, which will be subtracted from 
your ClinCard balance. 
 
How will information about me be kept private or confidential? 
 
All efforts will be made to keep your personal information in your research record confidential, but total 
confidentiality cannot be guaranteed. Rutgers will make every effort to keep the information collected 
from you private. In order to do so, we will assign all of your study materials (including your stored 
biological samples) a study number and remove all identifying information. All documents with your name 
on them will be kept in a locked file or encrypted (made impossible to read) on a computer. Only the study 
team will have access to this information. All staff associated with the project will be trained in procedures

for maintaining confidentiality. Results of the research may be presented at meetings or in publications, 
but your name and identity will never be disclosed. Sometimes, however, researchers need to share 
information that may identify you with people that work for the University, government regulators, or study 
sponsor 
 
A description of this clinical trial will be available on ClinicalTrials.gov, as required by U.S. law. This 
website will not include information that can identify you. At most, the website will include a summary of 
the results. You can search this website at any time. 
 
What will happen to my information or biospecimens collected for this research after the study is 
over? 
 
Nose swabs and blood specimens collected will be used for the purposes of this research.   
 
After information that could identify you has been removed, de-identified information and left over 
biospecimens collected for this research may be used by or distributed to investigators for other research 
without obtaining additional informed consent from you. Personal details that identify you, such as your 
name and date of birth, will not be shared in the future without your additional permission. 
 
What will happen if I am injured during this study? 
 
Participants in this study will be exposed to certain risks of personal injury in addition to those associated 
with standard forms of treatment, which include the risks of associated with Nitazoxanide, Ribavirin, and 
Hydroxychloroquine sulfate (the study medicines) that were described in the Risks section of this consent.  
In addition, it is possible that during the course of this study, new adverse effects of these medications 
that result in personal injury may be discovered. The University will make appropriate referrals for medical 
and/or dental treatment for subjects who sustain personal injuries or illnesses as a direct consequence of 
participation in the research. The subject’s health insurance carrier or other third-party payer (or Charity 
Care if there is no insurance) will be billed for the cost of this treatment; provided that the University shall 
not submit to federally funded programs, e.g., Medicare, Medicaid or CHAMPUS, for reimbursement first 
if submission to such programs is prohibited by law.  No financial compensation will be provided by the 
University and no other type of assistance is available from the University. However, by signing this form, 
you are not giving up any legal rights to seek further compensation. 
What will happen if I do not wish to take part in the study or if I later decide not to stay in the 
study? 
 
It is your choice whether to take part in the research. You may choose to take part, not to take part, or 
you may change your mind and withdraw from the study at any time. 
 
If you do not want to enter the study or decide to stop taking part, your relationship with the study staff will 
not change, and you may do so without penalty and without loss of benefits to which you are otherwise 
entitled. 
 
Beginning on the date that you withdraw your approval, no new personal health information will be used 
for research.  However, the study doctor/investigator may continue to use the health information that was 
provided before you withdrew your approval. To withdrawal your approval you must do this in writing to
