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.
Interventions
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.
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.

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. Arm 2: Standard care. 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.
