Brief summary:
The purpose of this study is to explore the efficacy of Aggrenox in patients with SARS-CoV-2 infection with symptoms consistent with COVID-19. An anticipated total of 132 participants will be randomly divided almost equally into 2 groups: one group will receive Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally along with the standard of care and the other group with receive the standard of care only but no Dipyridamole ER 200mg/ Aspirin 25mg. Participants will be screened, enrolled, receive treatment, and followed for 28 days. The clinical and laboratory outcomes of all the participants enrolled in the study will be evaluated at the end of the study to explore if there is any difference in the outcomes between 2 groups.

Detailed description:
Purpose/Specific Aims: The purpose of this study is to explore the efficacy of Aggrenox in patients with SARS-CoV-2 infection with symptoms consistent with COVID-19.

Among 132 SARS-CoV-2 patients (66 patients in each randomized arm), we will determine the efficacy of Aggrenox on clinical outcomes.

Hypotheses / Research Question(s) Compared to standard care, the addition of Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg), to standard care will result in improvement in the composite COVID ordinal scale at day 15. Additionally, combined Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally), and standard care will reduce the need for ventilation, length of mechanical ventilation, hospital length of stay, ICU length of stay, decrease risk of thromboembolic complications and improve survival more than standard care alone in SARS-CoV-2 patients.

Research Design and Methods Randomized design. Participants will be randomized 1:1 to Aggrenox or standard treatment. Arm 1: Active Comparator: (Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally).

Participants will receive Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally), 2 times daily (FDA-recommended dose) starting on the day of enrollment for a total of 2 weeks + standard care.

Arm 2: Standard care Comparator: Participants will receive standard care starting on the day of enrollment for a total of 2 weeks.

The investigators will perform a randomized, 2-arm, open-label single-site pilot study to evaluate the effect of oral Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally), on clinical outcomes in patients with SARS-CoV-2. In this research proposal, investigators will randomly assign 132 consenting participants with diagnosis of SARS-CoV-2 to two treatment groups: 1) Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally) + standard care and 2) standard care alone. Participants will be screened, enrolled, receive treatment and followed for 28 days. The study aim and procedure will be explained to every eligible subject and informed consent will be obtained from interested subjects or authorized proxy to participate in the study. The investigators will collect demographic, clinical, laboratory and radiological data. The patients would be followed daily for 2 weeks after enrollment while the patient is in the hospital and once discharged, they will be called every 3rd day to follow up on the symptoms.

Arms: arm 1: Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally plus standard care. Participants will receive Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally), 2 times daily starting on the day of enrollment for a total of 2 weeks. arm 2: Participants will receive standard care starting on the day of enrollment for a total of 2 weeks. Standard of care treatment consist of an intravenous Remidesivir 200 mg loading dose and then 100 mg/daily for a total of 4 days for non-intubated patients and 10 days for intubated patients, intravenous/oral decadron 6 mg/daily for 10 days and prophylactic subcutaneous LMWH daily, started on the day of enrollment and for the duration of hospitalization. If the patients are discharged before 10 days, they are prescribed oral decadron 6 mg daily to complete the course of 10 days.
Interventions: intervention 1: Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally AND Standard of care intervention 2: Standard of care
Intervention descriptions: intervention 1: Participants in the experimental group will receive Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally (if they have a feeding tube), 2 times daily starting on the day of enrollment for a total of 2 weeks. intervention 2: Participants will receive standard care starting on the day of enrollment for a total of 2 weeks. Standard of care treatment consist of an intravenous Remidesivir 200 mg loading dose and then 100 mg/daily for a total of 4 days for non-intubated patients and 10 days for intubated patients, intravenous/oral decadron 6 mg/daily for 10 days and prophylactic subcutaneous LMWH daily, started on the day of enrollment and for the duration of hospitalization. If the patients are discharged before 10 days, they are prescribed oral decadron 6 mg daily to complete the course of 10 days.

1.0 Research Design
1.1 Purpose/Specific Aims
The purpose of this study is to explore the efficacy of Aggrenox (Dipyridamole ER 200mg 
and Aspirin 25mg), in brand or generic formulation, in patients with SARS-CoV-2 infection 
with symptoms consistent with COVID-19. For ease, we will identify the drug as Aggrenox, 
regardless of the formulation.
Among 132 SARS-CoV-2 patients (66 patients in each randomized arm), we will 
determine the efficacy of Aggrenox on clinical outcomes.
A.  Endpoints:

resumption of normal activities; 2) not hospitalized, but unable to resume normal activities; 
3) hospitalized, not requiring oxygen; 4) hospitalized, requiring oxygen; 5) hospitalized, 
requiring high-flow oxygen therapy, or noninvasive ventilation; 6) hospitalized, requiring 
invasive ventilation; 7) ventilation plus additional organ support such as vasopressors, renal 
replacement therapy and ECMO and 8) death.
Secondary Endpoints:
1) all-cause mortality assessed on day 15 and day 28. 
2) oxygen-free days through day 28. 
3) invasive-ventilator-free days through day 28. 
4) ICU-free days through day 28.
5) hospital-free days through day 28. 
6) increase in cycle threshold (Ct) of SARS-CoV-2 PCR test as an approximation of decline 
in viral load at days 7 and 15. 
7) decrease in the markers D-dimer/ ferritin/ c-reactive protein at days 7 and 15.
8) thromboembolic complications including stroke at day 28.

B.  Hypotheses / Research Question(s)
Compared to standard care, addition of Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg), 
to standard care will result in improvement in composite COVID ordinal scale at day 15.

SARS-CoV-2 patients.
1.2 Research Significance

threat to public health worldwide.1,2. Thus, development of effective preventative and therapeutic 
interventions is paramount.
     Despite its importance, information about pathologic mechanisms of SARS-CoV-2 remains 
incomplete. Recent data suggests the role of exaggerated immune/inflammatory response and 
hypercoagulability as pathogenic mechanisms leading to clinical manifestations such as acute 
respiratory distress syndrome (ARDS), stroke and extrapulmonary multiorgan dysfunction.3 Due 
to the significant activation of coagulation system, the coagulopathy associated with COVID-19 
may result in thromboembolic complications such as deep venous thrombosis, pulmonary 
embolism and strokes.4 
Prophylactic anti-coagulation therapies have become the standard of care in the management 
of these patients.4 The International society of thrombosis and hemostasis has recommended 
that all COVID-19 patients admitted to the hospital, irrespective of the severity of their illness, 
should be started on prophylactic dose of low molecular weight heparin (LMWH).5 The Society 
of thrombosis and haemostasis research also recommended that all hospitalized COVID-19 
patients should receive pharmacological venous thromboembolism (VTE) prophylaxis unless 
contraindicated.6 Recent literature shows that the risk of thromboembolism is higher in patients 
admitted to the ICU. For the patients admitted to the ICU or having additional risk factors for 
VTE such as BMI> 30mkg/m2, history of VTE or rapidly rising D-dimer levels, high-risk 
prophylactic LMWH dosages twice daily should be considered.6 The therapeutic doses of either 
UFH or LMWH should be considered for those who have confirmed thrombosis including filter 
thrombosis.7 The anti-inflammatory properties of LMWH have been suggested to provide 
additional benefits in COVID-19 patients.4 
Utilization of a therapeutic that can simultaneously intervene along multiple pathways (viral 
replication, inflammation, vasoconstriction, and coagulation) can dramatically improve patient 
outcomes.    
Adenosine is a highly potent immunoregulatory nucleoside that interferes with inflammatory 
processes by modulating the biosynthesis and release of proinflammatory cytokines, slowing 
down the oxidative activity, preventing platelet aggregation, and reducing neutrophils adhesion 
and degranulation.8,9 One mechanism to increase extracellular adenosine is to inhibit 
intracellular uptake of adenosine and thereby capitalize on its anti-inflammatory properties. It 
has a wide-ranging effects on multiple organ systems by interacting with different adenosine 
receptors.9 Equilibrative nucleoside transporters (ENTs) are nucleoside transporters that 
regulate the flux of endogenous nucleosides, nucleobases and therapeutic analogs.10 Given the 
critical nature of regulating nucleosides in a number of pathological processes, ENTs have 
emerged as a druggable target. ENT inhibitors are used to modulate nucleosides in a number of 
disease states including viral infections such as HIV11, and tumors12.
     Dipyridamole (DIP) is one such ENT inhibitor (specific for the major and ubiquitous 
nucleoside transporter ENT-1), that inhibits nucleoside (adenosine) uptake into the endothelial 
and other cells and has been shown to enhance the anti-inflammatory and immunomodulatory 
effect of adenosine.13 A recent study has shown that DIP increases extracellular adenosine 
levels and thereby provides a significant decrease in CD8+T-cell activation and decreased 
macrophage activation among persons with HIV-1 infection on antiviral  therapy.11 
DIP may have additional therapeutic advantages to SARS-CoV-2 patients. DIP is a widely 
known phosphodiesterase (PDE) inhibitor with antiplatelet14 and vasodilatoratory15 effects. Of 
particular note, a recent screen of FDA approved drugs identified the ability of DIP to effectively

suppress SARS-CoV-2 replication with a therapeutically achievable EC50 concentration of 100 
nM.16 Moreover, a small study of 22 COVID-19 patients suggested improved outcomes 
including reduction in coagulation markers.17 These antiviral data are not without precedent as 
DIP has also been shown to have powerful antiviral activity against single-stranded RNA viruses 
in vitro, and in a VSV-induced viral pneumonia model in vivo.18-20 Additional possible benefits 
could include the anti-inflammatory action and promotion of mucosal healing.21 It may also 
prevent acute injury and progressive fibrosis of the lung, heart, liver, and kidney.22 In one small 
clinical series of 12 patients (pre-print, not peer-reviewed data), the authors used DIP as a 
prophylactic anti-coagulation therapy and reported significantly increased platelet and 
lymphocyte counts and decreased D-dimer levels in comparison to control patients. Two weeks 
after initiation of DIP therapy 60% of their severe patients and all patients with mild disease 
were discharged from the hospital.17 
     Aspirin is a well-known anti-platelet drug with anti-inflammatory properties. Aspirin inhibits 
platelet cyclooxygenase-1 activity that is essential for generation of thromboxane A2. 
Thromboxane A2 is a potent vasoconstrictor that also induces platelet aggregation and release 
of proinflammatory proteins from platelet storage granules. The literature evidence suggests 
that aspirin plus extended-release dipyridamole may be more suitable for preventing secondary 
stroke because, in addition to their antiplatelet actions, these drugs possess complementary 
anti-inflammatory properties.23
     Thus, we hypothesize that Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg 
orally/enterally), adjunctive therapy can be useful for SARS-CoV-2 infected patients through 
enhancing immune recovery, antiviral properties, and correcting the coagulation profile. 
     We propose a randomized, 2-arm, open-label single-site pilot study to evaluate the effect of 
oral/enteral Aggrenox on clinical outcomes in patients with SARS-CoV. We will randomly assign 
132 consenting participants to two treatment groups: 1) Aggrenox (Dipyridamole ER 200mg/ 
Aspirin 25mg orally/enterally), + standard care and 2) standard care alone. We will collect 
demographic, clinical, laboratory and radiological data. The patients would be followed daily for 
2 weeks after enrollment while the patient is in the hospital and once discharged, they will be 
called every 3rd day to follow up on the symptoms. 
1.2 Research Design and Methods
1: 1 Randomized design.
Arm 1: Aggrenox plus standard care. Participants will receive Aggrenox (Dipyridamole ER 
200mg/ Aspirin 25mg orally/enterally), 2 times daily (FDA–recommended dose) starting on the 
day of enrollment for a total of 2 weeks along with standard care.
Arm 2: Standard care. Participants will receive standard care starting on the day of enrollment 
for a total of 2 weeks. 
We will perform a randomized, 2-arm, open-label single-site pilot study to evaluate the effect of 
oral Aggrenox (Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally), on clinical outcomes in 
patients with SARS-CoV-2. In this research proposal, we will randomly assign 132 consenting 
participants with diagnosis of SARS-CoV-2 to two treatment groups: 1) Aggrenox (Dipyridamole 
ER 200mg/ Aspirin 25mg orally/enterally) + standard care and 2) standard care alone. 
Participants will be screened, enrolled, receive treatment and followed for 28 days. The study

aim and procedure will be explained to every eligible subject and informed consent will be 
obtained from interested subjects or authorized proxy to participate in the study. We do not 
anticipate problems with enrollment as sufficient number of COVID-19 patients are admitted at 
Rutgers-NJMS (approximately 2-5 new COVID-19 admissions daily, and total 18-20 patients 
who are currently admitted at Rutgers-NJMS with 5-6 patients in intensive care units).
Randomization. The P.I. or study coordinator will review the screening and enroll participants 
in the randomization. Once a participant has been randomized, we will conduct all evaluations 
irrespective of whether the participant starts the treatment, and how long the participants 
continues on the treatment or not. SARS-CoV-2 patients will be allocated in a 1:1 randomized 
fashion using computer generated random sequence to one of two groups: the Aggrenox 
(Dipyridamole ER 200mg/ Aspirin 25mg orally/enterally), plus standard care or the standard 
care. Data collection will end after 28 days, or the patient dies or withdraws consent.

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. 
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 and deemed secondary to the use of study drug: 

Results in death

Is immediately life-threatening

Requires in-patient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability or incapacity

Is a congenital abnormality or birth defect

Is an important medical event that may jeopardize the patient or may require medical   
intervention to prevent one of the outcomes listed above.
1.1.1
The causality of SAEs (their relationship to all study treatment/procedures) will be 
assessed by the investigator(s) and communicated to Boehringer Ingelheim (BI) via BI 
SAE form and the FDA via MedWatch form, if applicable. 
      Causality will be reported as either “Yes” or “No”.

Yes:
There is a reasonable causal relationship between the investigational product 
administered and the AE. 

No:
There is no reasonable causal relationship between the investigational product 
administered and the AE.

into the study and up to and including the 2 weeks follow-up period (after the completion of 2 
weeks of treatment with Aggrenox) for a total of 28 days . All grade 3 or higher AEs will be 
recorded. Grade 1-2 AEs do not need to be recorded. After withdrawal from treatment, subjects 
must be followed-up for all existing and new AEs for 14 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 DSMB and Rutgers IRB as per SOPs.). AEs will be 
recorded per Rutgers IRB SOPs. The common terminology criteria for adverse events (CTCAE) 
will be used as a reference to grade the adverse events.

All study-related adverse events/ 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 Rutgers IRB per the SOPs on the 
required forms. FDA will be informed per SOP, via a MedWatch, of any serious or unexpected 
adverse events that occur in 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. 
In addition to FDA, the Sponsor shall report all SAEs and non-serious AEs that occur 
,throughout the treatment period and up to and including the 2 weeks follow-up period (after the 
completion of 2 weeks of treatment with Aggrenox) for a total of 28 days which are relevant for a 
reported SAEs and any AEs relevant to a reported SAE  by fax or other secure method using BI 
IIS SAE form to the BI Unique Entry Point in accordance with timeline specified in the safety 
data exchange agreement . 
For each adverse event, the investigator will provide the onset date, end date, causality, 
intensity,treatment required, outcome, seriousness, and action taken with the investigational 
drug. 
The investigator does not need to actively monitor patients for adverse events once the clinical 
trial has ended. However, if the investigator becomes aware of an SAE(s) that occurred after the 
patient has completed the clinical trial (including any protocol specified follow-up period), it 
should be reported to BI if investigator considers it as relevant to the BI study drug.
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 14 days 
after the last dose of study medications) established in the protocol will be reported. 
Non-serious adverse events and SAEs will be collected from the time the patient is enrolled into 
the study, throughout the treatment period and up to and including the 2 weeks follow-up period 
(after the completion of 2 weeks of treatment with Aggrenox) for a total of 28 days. After 
withdrawal from treatment, subjects must be followed-up for all existing and new AEs for 14 
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, then they must be reported to the FDA 
as per their reporting criteria). 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. 
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 2 weeks 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, subjects must be followed-up for all existing and new AEs for 14 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 DSMB and Rutgers IRB as per 
SOPs.). AEs will be recorded per Rutgers IRB SOPs. 
•  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. 
•  Vital Signs
Temperature will be obtained at least two times a day (AM and PM). Nursing staff will record the 
temperature while the patient is in the hospital. Body temperature will be measured in degrees 
Fahrenheit using an automated thermometer. An automated thermometer will be provided to the 
patient once discharged from the hospital for checking the temperature at least once a day for 
the study duration (28 days total from the enrollment day). 
Study Efficacy/Response Assessments 
Change in composite COVID ordinal scale at day 15. Ordinal scale: 1) not hospitalized with 
resumption of normal activities; 2) not hospitalized, but unable to resume normal activities; 3) 
hospitalized, not requiring oxygen; 4) hospitalized, requiring oxygen; 5) hospitalized, requiring 
high-flow oxygen therapy, or noninvasive ventilation; 6) hospitalized, requiring invasive 
ventilation; 7) ventilation plus additional organ support such as pressors, renal replacement 
therapy and ECMO and 8) death.
Other response criteria used as secondary endpoints include the need of invasive ventilation, 
the days dependent on ventilator, hospital free days, thromboembolic complications, COVID 
ordinal scale at day 28 and mortality.

1.4 Preliminary Data
This is the first study of its kind. No preliminary data is available with the use of Aggrenox in 
patients with COVID-19. The use of Dipyridamole in a small unpublished study from China 
showed better outcomes in patients with COVID-19.17 
1.5 Sample Size Justification
The sample size of 132 patients (66 patients in each arm) was estimated to provide 90% power 
to detect a relative between-group difference of 20% reduction in composite ordinal scale (from 
day 0 to day 15) with assumption of mean composite ordinal scale value of 4.5 ± 1.6 (yes- this is 
SD) at baseline (day 0) and two-sided P value of 0.05.25 For primary efficacy, we will do an 
intention-to-treat analysis and include all patients who have undergone randomization and will 
adjust for the minimization variables. We will analyze continuous measures by means of linear 
regression and present as mean differences. For binary outcomes, we will present data as risk 
ratios from a binomial regression model.

Aspirin is an odorless white needle-like crystalline or powdery substance. When exposed to 
moisture, aspirin hydrolyzes into salicylic and acetic acids, and gives off a vinegary odor. It is 
highly lipid soluble and slightly soluble in water. 
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action 
The antithrombotic action of AGGRENOX is the result of the additive antiplatelet effects of 
dipyridamole and aspirin. 
Dipyridamole 
Dipyridamole inhibits the uptake of adenosine into platelets, endothelial cells and erythrocytes in 
vitro and in vivo; the inhibition occurs in a dose-dependent manner at therapeutic concentrations 
(0.5–1.9 μg/mL). This inhibition results in an increase in local concentrations of adenosine which 
acts on the platelet A2-receptor thereby stimulating platelet adenylate cyclase and increasing 
platelet cyclic-3',5'- adenosine monophosphate (cAMP) levels. Via this mechanism, platelet 
aggregation is inhibited in response to various stimuli such as platelet activating factor (PAF), 
collagen and adenosine diphosphate (ADP). 
Dipyridamole inhibits phosphodiesterase (PDE) in various tissues. While the inhibition of cAMP-
PDE 
is weak, therapeutic levels of dipyridamole inhibit cyclic-3',5'-guanosine monophosphate-PDE 
(cGMP- PDE), thereby augmenting the increase in cGMP produced by EDRF (endothelium-
derived relaxing factor, now identified as nitric oxide). 
Aspirin 
Aspirin inhibits platelet aggregation by irreversible inhibition of platelet cyclooxygenase and thus 
inhibits the generation of thromboxane A2, a powerful inducer of platelet aggregation and 
vasoconstriction. 
Pharmacodynamics 
The effect of either agent on the other's inhibition of platelet reactivity has not been evaluated. 
Pharmacokinetics 
There are no significant interactions between aspirin and dipyridamole. The kinetics of the 
components are unchanged by their co-administration as AGGRENOX. 
Absorption

Peak plasma levels of dipyridamole are achieved 2 hours (range 1–6 hours) after administration 
of a daily dose of 400 mg AGGRENOX (given as 200 mg BID). The peak plasma concentration 
at steady- state is 1.98 μg/mL (1.01–3.99 μg/mL) and the steady-state trough concentration is 
0.53 μg/mL (0.18– 1.01 μg/mL). 
Aspirin: 
Peak plasma levels of aspirin are achieved 0.63 hours (0.5–1 hour) after administration of a 50 
mg aspirin daily dose from AGGRENOX (given as 25 mg BID). The peak plasma concentration 
at steady- state is 319 ng/mL (175–463 ng/mL). Aspirin undergoes moderate hydrolysis to 
salicylic acid in the liver and the gastrointestinal wall, with 50%–75% of an administered dose 
reaching the systemic circulation as intact aspirin. 
Effect of Food 
Dipyridamole: 
When AGGRENOX capsules were taken with a high fat meal, dipyridamole peak plasma levels 
(Cmax) and total absorption (AUC) were decreased at steady-state by 20-30% compared to 
fasting. Due to the similar degree of inhibition of adenosine uptake at these plasma 
concentrations, this food effect is not considered clinically relevant. 
Aspirin: 
When AGGRENOX capsules were taken with a high fat meal, there was no difference for 
aspirin in AUC at steady-state, and the approximately 50% decrease in Cmax was not 
considered clinically relevant based on a similar degree of cyclooxygenase inhibition comparing 
the fed and fasted state. 
Distribution 
Dipyridamole: 
Dipyridamole is highly lipophilic (log P=3.71, pH=7); however, it has been shown that the drug 
does not cross the blood-brain barrier to any significant extent in animals. The steady-state 
volume of distribution of dipyridamole is about 92 L. Approximately 99% of dipyridamole is 
bound to plasma proteins, predominantly to alpha 1-acid glycoprotein and albumin. 
Aspirin: 
Aspirin is poorly bound to plasma proteins and its apparent volume of distribution is low (10 L). 
Its metabolite, salicylic acid, is highly bound to plasma proteins, but its binding is concentration-
dependent (nonlinear). At low concentrations (<100 mcg/mL), approximately 90% of salicylic 
acid is bound to albumin. Salicylic acid is widely distributed to all tissues and fluids in the body, 
including the central nervous system, breast milk, and fetal tissues. Early signs of salicylate 
overdose (salicylism), including tinnitus (ringing in the ears), occur at plasma concentrations 
approximating 200 mcg/mL. 
Metabolism and Elimination 
Dipyridamole: 
Dipyridamole is metabolized in the liver, primarily by conjugation with glucuronic acid, of which 
monoglucuronide which has low pharmacodynamic activity is the primary metabolite. In plasma,

about 80% of the total amount is present as parent compound and 20% as monoglucuronide. 
Most of the glucuronide metabolite (about 95%) is excreted via bile into the feces, with some 
evidence of enterohepatic circulation. Renal excretion of parent compound is negligible and 
urinary excretion of the glucuronide metabolite is low (about 5%). With intravenous (i.v.) 
treatment of dipyridamole, a triphasic profile is obtained: a rapid alpha phase, with a half-life of 
about 3.4 minutes, a beta phase, with a half- life of about 39 minutes, (which, together with the 
alpha phase accounts for about 70% of the total area under the curve, AUC) and a prolonged 
elimination phase λz with a half-life of about 15.5 hours. Because of the extended absorption
phase of the dipyridamole component, only the terminal phase is apparent from oral treatment 
with AGGRENOX which was 13.6 hours. 
Aspirin: 
Aspirin is rapidly hydrolyzed in plasma to salicylic acid, with a half-life of 20 minutes. Plasma 
levels of aspirin are essentially undetectable 2–2.5 hours after dosing and peak salicylic acid 
concentrations occur 1 hour (range: 0.5–2 hours) after administration of aspirin. Salicylic acid is 
primarily conjugated in the liver to form salicyluric acid, a phenolic glucuronide, an acyl 
glucuronide, and a number of minor metabolites. Salicylate metabolism is saturable and total 
body clearance decreases at higher serum concentrations due to the limited ability of the liver to 
form both salicyluric acid and phenolic glucuronide. Following toxic doses (10–20 g), the plasma 
half-life may be increased to over 20 hours. 
The elimination of acetylsalicylic acid follows first-order kinetics with AGGRENOX and has a 
half- life of 0.33 hours. The half-life of salicylic acid is 1.71 hours. Both values correspond well 
with data from the literature at lower doses which state a resultant half-life of approximately 2–3 
hours. At higher doses, the elimination of salicylic acid follows zero-order kinetics (i.e., the rate 
of elimination is constant in relation to plasma concentration), with an apparent half-life of 6 
hours or higher. Renal excretion of unchanged drug depends upon urinary pH. As urinary pH 
rises above 6.5, the renal clearance of free salicylate increases from <5% to >80%. 
Alkalinization of the urine is a key concept in the management of salicylate overdose [see 
Overdosage (10)]. Following therapeutic doses, about 10% is excreted as salicylic acid and 
75% as salicyluric acid, as the phenolic and acyl glucuronides, in urine. 
Specific Populations 
Geriatric Patients: 
Dipyridamole: 
In ESPS2 [see Clinical Studies (14)], plasma concentrations (determined as AUC) of 
dipyridamole in healthy elderly subjects (>65 years) were about 40% higher than in subjects 
younger than 55 years receiving treatment with AGGRENOX. 
Hepatic Dysfunction: 
No study has been conducted with AGGRENOX in patients with hepatic dysfunction. 
Dipyridamole: 
In a study conducted with an intravenous formulation of dipyridamole, patients with mild to 
severe hepatic insufficiency showed no change in plasma concentrations of dipyridamole but 
showed an increase in the pharmacologically inactive monoglucuronide metabolite. 
Dipyridamole can be dosed without restriction as long as there is no evidence of hepatic failure.

Aspirin: 
Avoid aspirin in patients with severe hepatic insufficiency. 
Renal Dysfunction: 
Dipyridamole: 
In ESPS2 patients [see Clinical Studies (14)], with creatinine clearances ranging from about 15 
mL/min to >100 mL/min, no changes were observed in the pharmacokinetics of dipyridamole or 
its glucuronide metabolite if data were corrected for differences in age. 
Aspirin: 
Avoid aspirin in patients with severe renal failure (glomerular filtration rate <10 mL/min). Drug 
Interaction Studies 
A dedicated drug interaction study was conducted in 60 healthy volunteers to evaluate the 
effects of omeprazole 80 mg administered once daily on the pharmacokinetics (PK) of 
dipyridamole and the pharmacodynamics (PD) of acetylsalicylic acid when co-administered with 
AGGRENOX twice daily. Dipyridamole exposure (Cmax and AUC) at steady-state were similar 
with or without omeprazole co- administration. The pharmacokinetics of acetylsalicylic acid was 
not characterized. However, the antiplatelet activity as measured by arachidonic acid induced 
platelet aggregation was similar between the treatment arms at steady-state. 
NONCLINICAL TOXICOLOGY
Carcinogenesis, Mutagenesis, Impairment of Fertility 
In studies in which dipyridamole was administered in the feed to mice (up to 111 weeks in males 
and females) and rats (up to 128 weeks in males and up to 142 weeks in females), there was no 
evidence of drug-related carcinogenesis. The highest dose administered in these studies (75 
mg/kg/day) was, on a 2 mg/m basis, about equivalent to the maximum recommended daily 
human oral dose(MRHD )in mice and about twice the MRHD in rats. 
Combinations of dipyridamole and aspirin (1:5 ratio) tested negative in the Ames test, in vivo 
chromosome aberration tests (in mice and hamsters), oral micronucleus tests (in mice and 
hamsters) and oral dominant lethal test (in mice). Aspirin, alone, induced chromosome 
aberrations in cultured human fibroblasts. Mutagenicity tests of dipyridamole alone with bacterial 
and mammalian cell systems were negative. 
Combinations of dipyridamole and aspirin have not been evaluated for effects on fertility and 
reproductive performance. There was no evidence of impaired fertility when dipyridamole was 
administered to male and female rats at oral doses up to 500 mg/kg/day (about 12 times the 
MRHD on a mg/m2 basis). A significant reduction in number of corpora lutea with consequent 
reduction in implantations and live fetuses was, however, observed at 1250 mg/kg (more than 
30 times the MRHD on a mg/m2 basis). Aspirin inhibits ovulation in rats.

4.7 Risks of Harm/Potential for Benefits to Subjects
A. Description of Risks of Harm to Subjects
Reasonably Foreseeable Risks of Harm (this data I got from Aggrenox product 
information available online- Appendix is attached for your review)) 
Risk of Bleeding
AGGRENOX increases the risk of bleeding. 
Risk factors for bleeding include the use of other drugs that increase the risk of bleeding (e.g., 
anticoagulants, antiplatelet agents, heparin, anagrelide, fibrinolytic therapy, and chronic use of 
NSAIDs). 
Intracranial Hemorrhage In European Stroke Prevention Study-2 (ESPS2), the annualized event 
rate for intracranial hemorrhage was 0.39%/year in the AGGRENOX group, 0.26%/year in the 
extended-release dipyridamole (ER-DP) group, 0.24%/year in the aspirin (ASA) group, and 
0.29%/year in the placebo groups. 
Gastrointestinal (GI) Side Effects 
GI side effects include stomach pain, heartburn, nausea, vomiting, and gross GI bleeding. 
Although minor upper GI symptoms, such as dyspepsia, are common and can occur anytime 
during therapy, physicians should remain alert for signs of ulceration and bleeding, even in the 
absence of previous GI symptoms. Inform patients about the signs and symptoms of GI side 
effects and what steps to take if they occur. In ESPS2, the annualized event rate for 
gastrointestinal bleeding was 2.97%/year in the AGGRENOX group, 1.58%/year in the 
extended-release dipyridamole group, 2.06%/year in the aspirin group, and 1.40%/year in the 
placebo groups. 
Peptic Ulcer Disease 
Avoid using aspirin in patients with a history of active peptic ulcer disease, which can cause 
gastric mucosal irritation and bleeding. 
Alcohol Warning 
Because AGGRENOX contains aspirin, counsel patients who consume three or more alcoholic 
drinks every day about the bleeding risks involved with chronic, heavy alcohol use while taking 
aspirin. 
Renal Failure 
Avoid aspirin in patients with severe renal failure (glomerular filtration rate less than 10 
mL/minute) [see Use in Specific Populations. 
Hepatic Insufficiency 
Elevations of hepatic enzymes and hepatic failure have been reported in association with 
dipyridamole administration.
Coronary Artery Disease

Dipyridamole has a vasodilatory effect. Chest pain may be precipitated or aggravated in patients 
with underlying coronary artery disease who are receiving dipyridamole. For stroke or TIA 
patients for whom aspirin is indicated to prevent recurrent myocardial infarction (MI) or angina 
pectoris, the aspirin in this product may not provide adequate treatment for the cardiac 
indications. 
Hypotension 
Dipyridamole produces peripheral vasodilation, which can exacerbate pre-existing hypotension.
Stress Testing with Intravenous Dipyridamole and Other Adenosinergic Agents 
Clinical experience suggests that patients being treated with AGGRENOX capsules who also 
require pharmacological stress testing with intravenous dipyridamole or other adenosinergic 
agents (e.g. adenosine, regadenoson) should interrupt AGGRENOX capsules for 48 hours prior 
to stress testing. 
Intake of AGGRENOX capsules within 48 hours prior to stress testing with intravenous 
dipyridamole or other adenosinergic agents may increase the risk for cardiovascular side effects 
of these agents and may impair the sensitivity of the test. 
Drug Interaction Study Information Obtained From Literature
Adenosinergic agents (e.g. adenosine, regadenoson)
Dipyridamole has been reported to increase the plasma levels and cardiovascular effects of 
adenosine. Adjustment of adenosine dosage may be necessary. Dipyridamole also increases 
the cardiovascular effects of regadenoson, an adenosine A2A-receptor agonist. The potential 
risk of cardiovascular side effects with intravenous adenosinergic agents may be increased 
during the testing period when dipyridamole is not held 48 hours prior to stress testing. 
Angiotensin Converting Enzyme (ACE) Inhibitors 
Because of the indirect effect of aspirin on the renin-angiotensin conversion pathway, the 
hyponatremic and hypotensive effects of ACE inhibitors may be diminished by concomitant 
administration of aspirin. 
Acetazolamide 
Concurrent use of aspirin and acetazolamide can lead to high serum concentrations of 
acetazolamide (and toxicity) due to competition at the renal tubule for secretion. 
Anticoagulants and Antiplatelets 
Patients taking AGGRENOX in combination with anticoagulants, antiplatelets, or any substance 
impacting coagulation are at increased risk for bleeding. Aspirin can displace warfarin from 
protein binding sites, leading to prolongation of both the prothrombin time and the bleeding time. 
Aspirin can increase the anticoagulant activity of heparin, increasing bleeding risk. 
Anagrelide 
Patients taking aspirin in combination with anagrelide are at an increased risk of bleeding. 
Anticonvulsants 
Salicylic acid can displace protein-bound phenytoin and valproic acid, leading to a decrease in 
the total concentration of phenytoin and an increase in serum valproic acid levels.

Beta Blockers 
The hypotensive effects of beta blockers may be diminished by the concomitant administration 
of aspirin due to inhibition of renal prostaglandins, leading to decreased renal blood flow and 
salt and fluid retention. 
Cholinesterase Inhibitors 
Dipyridamole may counteract the anticholinesterase effect of cholinesterase inhibitors, thereby 
potentially aggravating myasthenia gravis. 
Diuretics 
The effectiveness of diuretics in patients with underlying renal or cardiovascular disease may be 
diminished by the concomitant administration of aspirin due to inhibition of renal prostaglandins, 
leading to decreased renal blood flow and salt and fluid retention. 
Methotrexate 
Salicylate can inhibit renal clearance of methotrexate, leading to bone marrow toxicity, 
especially in the elderly or renal impaired. 
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) 
The concurrent use of aspirin with other NSAIDs may increase bleeding or lead to decreased 
renal function. 
Oral Hypoglycemics 
Moderate doses of aspirin may increase the effectiveness of oral hypoglycemic drugs, leading 
to hypoglycemia. 
Uricosuric Agents (probenecid and sulfinpyrazone) 
Salicylates antagonize the uricosuric action of uricosuric agents.

Elevations of hepatic enzymes and hepatic failure have been reported in association with 
dipyridamole administration.
•
Coronary Artery Disease 
Dipyridamole has a vasodilatory effect. Chest pain may be precipitated or aggravated in 
patients with underlying coronary artery disease who are receiving dipyridamole. For stroke 
or TIA patients for whom aspirin is indicated to prevent recurrent myocardial infarction (MI) 
or angina pectoris, the aspirin in this product may not provide adequate treatment for the 
cardiac indications. 
•
Peptic Ulcer Disease 
Avoid using aspirin in patients with a history of active peptic ulcer disease, which can cause 
gastric mucosal irritation and bleeding. 
•
Other Foreseeable Risks of Harm
One potential risk is loss of confidentiality. We have taken several steps to minimize the 
probability of this risk.

Observation and Sensitive Information 
      N/A 
Procedures which Risk Harm to Embryo, Fetus, and/or Pregnant Subjects
Pregnancy 
Risk Summary 
Available data from published studies and postmarketing experience with AGGRENOX use 
during pregnancy have not identified a clear association between AGGRENOX use and major 
birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). AGGRENOX 
contains low-dose aspirin which is an NSAID (see Clinical Considerations). In animal 
reproduction studies, there were adverse developmental effects with administration of aspirin in 
rats and rabbits at doses about 66 and 44 times, respectively, the human exposure at the 
maximum recommended daily dose of aspirin-dipyridamole. Reproduction studies with 
dipyridamole in mice, rabbits, and rats have revealed no evidence of harm to the fetus up to 
doses about 25 times the maximum recommended daily human dose of aspirin/dipyridamole. 
Nonclinical data are suggestive of a possible potentiation of aspirin-related fetal toxicity when 
combined with dipyridamole (see Data). 
The estimated background risk of major birth defects and miscarriage for the indicated 
population is unknown. All pregnancies have a background risk of birth defect, loss, or other 
adverse outcomes. In the U.S. general population, the estimated background risk of major birth 
defects and miscarriage in clinically recognized pregnancies is 2-4 and 15-20%, respectively. 
Clinical Considerations 
Labor and Delivery 
AGGRENOX, which contains dipyridamole and low-dose aspirin, increases the risk for bleeding.

Maternal use of high-dose aspirin can result in excessive blood loss at delivery, prolonged 
gestation, prolonged labor, intracranial hemorrhage in premature infants, low birth weight, 
stillbirth, and neonatal death. Data Human Data Published data from clinical trials, observational 
studies, case series, and case reports over several decades have not identified a clear 
association between aspirin-dipyridamole use in pregnancy and major birth defects, 
miscarriage, or adverse maternal or fetal outcomes. However, these studies cannot definitively 
establish the absence of any aspirin-dipyridamole associated risks. Methodological limitations of 
these studies include variability in the timing and dose of drug exposure (e.g., most exposures 
occurred beyond the first trimester) and the small sample sizes of individual studies. 
Animal Data 
Aspirin has been shown to be teratogenic in rats (spina bifida, exencephaly, microphthalmia and 
coelosomia) and rabbits (congested fetuses, agenesis of skull and upper jaw, generalized 
edema with malformation of the head, and diaphanous skin) at oral doses of 330 mg/kg/day and 
110 mg/kg/day, respectively. These doses, which also resulted in a high resorption rate in rats 
(63% of implantations versus 5% in controls), are, on a mg/m basis, about 66 and 44 times, 
respectively, the dose of aspirin contained in the maximum recommended daily human dose of 
aspirin-dipyridamole. Reproduction studies with dipyridamole have been performed in mice, 
rabbits and rats at oral doses of up to 125 mg/kg, 40 mg/kg, and 1000 mg/kg, respectively 
(about 1½, 2, and 25 times the maximum recommended daily human oral dose, respectively, on 
a mg/m basis) and have revealed no evidence of harm to the fetus due to dipyridamole. When 
330 mg aspirin/kg/day was combined with 75 mg dipyridamole/kg/day in the rat at doses about 
66 and 2 times, respectively, the maximum recommended daily human dose, the resorption rate 
approached 100%. 
Lactation 
Risk Summary 
Based on data from a clinical lactation study in breastfeeding women taking low-dose aspirin, 
the metabolite salicylic acid is present in human milk in low levels (see Data). Dipyridamole is 
also present in human milk. There is no information on the effects of AGGRENOX or 
dipyridamole on the breastfed infant or on milk production. There is insufficient information to 
determine the effects of aspirin on the breastfed infant and no information on the effects of 
aspirin on milk production. The developmental and health benefits of breastfeeding should be 
considered along with the mother's clinical need for AGGRENOX and any potential adverse 
effects on the breastfed child from AGGRENOX or from the underlying maternal condition. 
Data 
A published clinical study involved six exclusively breastfeeding women at 1 to 8 months 
postpartum who were taking 81 mg aspirin daily. Milk samples were collected at steady state, at 
0, 1, 2, 4, 8, 12, and 24 hours after taking a dose of aspirin. Aspirin was undetectable in human 
milk. Salicylic acid was present in milk at low levels (average concentration of 24 ng/mL). Based 
on an average milk consumption of 150 mL/kg/day, the calculated relative infant dose was 
0.4%. No adverse effects on the breastfed infants were noted.

Of the total number of subjects in ESPS2, 61% were 65 and over, while 27% were 75 and over. 
No overall differences in safety or effectiveness were observed between these subjects and 
younger subjects, and other reported clinical experience has not identified differences in 
responses between the elderly and younger patients, but greater sensitivity of some older 
individuals cannot be ruled out.  
Patients with Severe Hepatic or Severe Renal Dysfunction 
AGGRENOX has not been studied in patients with hepatic or renal impairment. Avoid using 
aspirin containing products, such as AGGRENOX, in patients with severe hepatic or severe 
renal (glomerular filtration rate). 
C. Risks of Harm to Non-Subjects 
The patient will be given a mask immediately upon arrival and escorted to a private room with a 
closed door. 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 a nasopharyngeal swab to collect 
viral load specimens during this study is not considered an aerosolizing procedure.

Ensuring that the conditions under which a procedure is performed or information is 
collected (e.g., physical locations, telephone contact, mail or email solicitations) afford 
protections against interactions with participants being witnessed, overheard or 
inadvertently intercepted or viewed. 
•
Limiting the information being collected to only the minimum amount of data necessary 
to accomplish the research purposes. 
The research team will make all efforts to ensure confidentiality is maintained by: 
•
Protecting PHI against public viewing; 
•
Proper storage and disposal of documents that contain PHI; 
•
Safeguarding computer workstations and databases that access PHI. 
F. Potential Benefits to Subjects 
There may be direct benefit to the patient for participation in this study because the study 
participant will receive Aggrenox, which is FDA approved and Dipyridamole has been shown to 
have some benefit in a small series of COVID-19 patients in an unpublished study from China. 
Although this does not guarantee that each individual patient will benefit. 
Data gathered from this study may allow us to identify an effective treatment for COVID-19 that 
could result in benefit to the patient or society as whole in the future.

6.0 Data Management Plan
6.1 Data Analysis
The sample size of 132 patients (66 patients in each arm) was estimated to provide 90% power 
to detect a relative between-group difference of 20% reduction in composite ordinal scale (from 
day 0 to day 15) with assumption of mean composite ordinal scale value of 4.5 ± 1.6 (yes) at 
baseline (day 0) and two-sided P value of 0.05.20 For primary efficacy, we will do an intention-to-
treat analysis and include all patients who have undergone randomization and will adjust for the 
minimization variables. We will analyze continuous measures by means of linear regression and 
present as mean differences. For binary outcomes, we will present data as risk ratios from a 
binomial regression model.

6.3 Data and Safety Monitoring
A. Data/Safety Monitoring Plan
The Principal Investigators will be responsible for monitoring the data, assuring protocol 
compliance, and conducting the safety reviews at the specified frequency, which must be 
conducted at a minimum of once a month (including when re-approval of the protocol is sought). 
The Rutgers Cancer Institute of New Jersey’s Human Research Oversight Committee (HROC) 
will be the DSMB of record. During the review process, the principal investigators (serving as 
monitor) will evaluate whether the study should continue unchanged, require 
modification/amendment, or close to enrollment. Either principal investigator, IRB or either Data 
or Safety Monitoring Committee have the authority to stop or suspend the study or require 
modifications at each institution. The PIs will be responsible for sharing this information in a 
timely fashion and coordinating appropriate parallel actions at the other institution. 
An audit will be conducted following enrollment of the first two (2) or three (3) patients. 
Subsequent audits will occur dependent on the rate of enrollment. More frequent audits of 
patient data and study conduct will occur if necessary. Prior audit findings and/or situations that 
may arise during the study will determine the need for more frequent auditing. All audit findings 
will be discussed with the principal investigator and the Rutgers University IRB.

CONSENT TO TAKE PART IN A RESEARCH STUDY
Title of Study: Aggrenox in Treatment of Patients with COVID-19: A Randomized Controlled 
Trial.
Principal Investigator: Amit Singla, MD, FAANS
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: explore the efficacy of Aggrenox (Aspirin-Dipyridamole) 
in patients with SARS-CoV-2 infection with symptoms consistent with COVID-19.
If you take part in the research, you will be asked to be a part of one of the 2 groups based on 
randomization; one group, the treatment group, will be given Aggrenox capsule twice a day in 
addition to standard care for COVID treatment and other group, the Standard care 
Comparator group will not be getting any additional drug apart from the standard care for 
COVID infection. 
The patients in the treatment group will receive Aggrenox (Dipyridamole ER 200mg/ Aspirin 
25mg orally), 2 times daily (FDA–recommended dose) starting on the day of enrollment for a 
total of 2 weeks + standard care. You will be given this medication for a total of 2 weeks after 
enrollment. During the hospital stay, you will be checked by the research coordinator to follow 
your symptoms and will get the labs and swabs done, which are part of your care for COVID 
infection. Once discharged, you will be called on day 15 and day 28 by the research 
coordinator to follow up on your symptoms.  This intervention for COVID patients is 
experimental, based on the literature evidence that COVID patients have higher tendency to 
form clots in blood vessels, and can also have an overblown response to the COVID infection 
call an inflammatory response. This medication is designed to prevent inflammation and 
blood clots.
Patients in the Standard care Comparator group will receive standard care starting on the day 
of enrollment for a total of 2 weeks. 
Possible harms or burdens of taking part in the study may be increased risk of bleeding, 
Gastrointestinal (GI) Side Effects such as nausea, vomiting, painful or difficult digestion, ulcer, 
GI bleeding. Chest pain could occur in patients with existing diseases of the blood vessels of 
the heart, low blood pressure, or an allergy to the drug You may feel discomfort and/or pain 
during some of the tests or procedures in the study. Your condition may not improve and 
could even worsen if you take part in this study. 
Possible benefits of taking part may be that the group that receives Aggrenox (Aspirin-
Dipyridamole) could do better, such as having a decreased risk of death, cut down the 
chance of needing the ventilator, a machine that helps you breathe, and less time in the 
hospital.  
Information learned from the study may help other people in the future. However, it is possible 
that you will not receive any direct personal benefit from taking part in this study.

Sponsor of the Study: Amit Singla, MD is the sponsor-investigator (the physician in charge) of 
this research study. He works at the New Jersey Medical School. Boehringer Ingelheim
Pharmaceuticals Inc. (BIPI) is the funding source for the study and supplying Aggrenox 
(Aspirin-Dipyridamole) (study drug) for this study and may request access to study records. 
Why is this study being done?
Coronavirus disease 2019 (COVID-19) is a lung illness that can spread from person to person. 
The virus that causes COVID-19 is a novel coronavirus that was first identified during an 
investigation into an outbreak in Wuhan, China.  There is currently no FDA approved treatment 
for COVID-19.
The purpose of the research is to determine if the addition of Aggrenox (Aspirin-Dipyridamole) 
to your standard of care treatment can improve symptoms in patients with COVID-19. The use 
of Aggrenox (Aspirin-Dipyridamole) has not been approved by the FDA for treatment of COVID-
19 and is experimental in this study.
Since we do not know which study treatment is better, we will compare the study groups.  A 
computer will assign you to one of two groups in the study.  This is called randomization and is 
done by chance like the flipping of a coin.  One group will receive Aggrenox (Aspirin-
Dipyridamole) and the other will not.  Neither you nor the study doctor will choose the group you 
get.

What are the risks of harm or discomforts I might experience if I take part in this study?
You may have side effects while on this study. Everyone taking part in the study will be watched 
carefully for any side effects. However, doctors do not know all the side effect that may happen. 
Side effects may be mild or very serious. Your study doctor may give you medicines to help 
lessen side effects. Your study doctor may also decide that it is necessary to delay or stop the 
study treatment. Many side effects go away soon after you stop taking the drugs. In some 
cases, side effects can be serious, long lasting, or never go away. You should talk with your 
study doctor about any side affects you may have while taking part in the study. 
•
Risk of Bleeding
AGGRENOX (Aspirin-Dipyridamole) (the study drug) increases the risk of bleeding. 
If you are on other blood thinner drugs such as Coumadin/Warfarin, therapeutic Heparin, 
Plavix/Clopidogrel, Brilinta, Eliquis, the risk of bleeding from Aggrenox (Aspirin-
Dipyridamole) increases. This risk is less than 5% based on the studies. 
•
Gastrointestinal (GI) Side Effects 
You can have GI side effects such as stomach pain, heartburn, nausea, vomiting, and gross 
GI bleeding. Minor upper GI symptoms, such as dyspepsia, are common and can occur 
anytime during therapy; if they happen and can be tolerated with or without the addition of 
anti-acidity medications such as Pepcid, you will be requested to continue to be in the study 
group. You will be monitored closely for signs of ulceration and bleeding, even in the 
absence of previous GI symptoms. If the serious GI bleeding happens or the GI ulcer is 
diagnosed during the study, the study drug will be discontinued. This risk is less than 5% 
based on the studies.
•
Peptic Ulcer Disease 
If you have a history of gastric/ intestinal ulcer, please let the study team know and you will 
not be included in the study due to a higher risk of bleeding. 
•
Alcohol Warning 
Due to the bleeding risk involved, if you have a history of chronic, heavy alcohol use, you 
will not be included in the study as a study participant. 
•
Coronary Artery Disease 
The study drug component Dipyridamole has a vasodilatory effect and it may precipitate 
chest pain if you have an underlying disease of the blood vessels of the heart. If you have a 
recent/recurrent heart attack or unstable angina (recurrent chest pains related to heart), you 
will not be included in the study as a study participant.  
•
Hypotension 
If you have a history of low blood pressure, the study drug may worsen pre-existing 
hypotension (low blood pressure). You will be closely watched for the change in blood

pressure after starting the study drug and if your blood pressure becomes too low and if 
deemed significant by the study team, you will be removed from the study as a study 
participant. 
•
Stress Testing with Intravenous Dipyridamole and Other Adenosinergic Agents  
(e.g. adenosine, regadenoson)
If while you are taking Aggrenox (Aspirin-Dipyridamole), you should need to have a stress 
test, we will temporarily stop your Aggrenox (Aspirin-Dipyridamole) treatment 48 hours prior 
to your scheduled stress test. 
Risk of Harm from an Intervention on a Subject with an Existing Condition 
•
Renal Failure 
If you have a history of severe kidney failure you will not be included in the study as a study 
participant. 
•
Liver Insufficiency 
If you have a history of severe liver failure you will not be included in the study as a study 
participant. 
Other Foreseeable Risks of Harm
One potential risk from being a study participant is loss of confidentiality of your health 
information. We have taken several steps to minimize the probability of this risk to you. 
Reproductive Risks of Harm
Available data from published studies and post marketing experience with AGGRENOX 
(Aspirin-Dipyridamole) use during pregnancy have not identified a clear association between 
AGGRENOX (Aspirin-Dipyridamole) use and major birth defects, miscarriage, or adverse 
maternal or fetal outcomes.
All women of child bearing potential involved in the study must use one of the approved 
methods of contraception or be abstinent from sexual intercourse for the duration of study. 
Likewise, for men with partners of child bearing potential should notify their partners about 
taking study drug and either be abstinent from sexual intercourse for the duration of study or 
use one of the approved methods of contraception.
Other risks/ cautions: 
You should not take any new over-the-counter medicines, herbal products, vitamins or food 
supplements while taking part in this study, unless you tell the study doctor and get permission 
from the study doctor to go on taking these medicines.  You will follow the instructions of the 
study doctor about the use of any of these products.
You should also tell the study doctor about all medicines that other doctors may have prescribed 
for you to take.
Are there any benefits to me if I choose to take part in this study?
The benefits of taking part in this study may be better clinical outcomes in the group which 
receive Aggrenox (Aspirin-Dipyridamole) such as decreased risk of mortality, decreased risk of 
needing the ventilator, reduced hospital stay. Dipyridamole has been shown to have some
