The purpose of this study is to assess the safety and efficacy of orally administered NLRP3 inhibitor, dapansutrile, for the treatment of moderate COVID-19 symptoms and early cytokine release syndrome (CRS) in patients with confirmed SARS-CoV-2 infection and moderate symptoms. Coronavirus disease 2019 (COVID-19) is caused by infection from a new strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 is characterized by fever, cough and shortness of breath, which in certain patients can lead to systemic organ failure and mortality. The data show that SARS-CoV-2 activates the innate immune signaling sensor NLRP3. Activation of NLRP3 initiates the cytokine release syndrome (CRS), which includes the production of primary cytokine, IL-1, triggering an intense inflammatory response that is prevalent in symptomatic COVID-19 patients. When CRS advances further to a fulminant 'cytokine storm', the data show that respiratory distress syndrome and multiple-organ failure take place. A specific inhibitor of NLRP3, dapansutrile may reduce or prevent the hyperinflammation associated with CRS by inhibiting the production of IL-1β early to arrest the progression to a severe 'cytokine storm.' The end result would be a reduction in the need for COVID-19 patients to receive intensive medical treatment, allowing for fewer hospitalizations, administration of mechanical ventilation and deaths.

Subjects with moderate COVID-19 consistent with the definition of "moderate" as set forth by the February 2021 FDA Guidance for Industry: COVID-19: Developing Drugs and Biological Products for Treatment or Prevention (FDA, 2021) who at the Screening/Baseline/Day 1 Visit: 1. have felt feverish within the past 24 hours, 2. have an SpO2 > 93% on room air at sea level when sitting, and 3. meet at least one of the following criteria: i). Respiratory rate: = 20 breaths/minute, when the subject is sitting, ii). SpO2: = 96% on room air at sea level, when the subject is sitting, iii).

At the time of screening if the subject is on anti- hypertensive medication(s) and diastolic or systolic rates are elevated, subject may be enrolled after consultation with the Medical Monitor, 5. Known respiratory disease (including asthma or chronic obstructive pulmonary disease [COPD]), 6. Known heart failure (note: subjects with New York Heart Association Class IV congestive heart failure cannot be enrolled per Exclusion Criterion 4), or 7. Known coronary disease; 6. Plasma CRP level must be collected at Screening/Baseline/Day 1 Visit; 7. Acceptable overall medical condition to be safely enrolled in and complete the study (with specific regard to cardiovascular, renal, and hepatic conditions) in the opinion of the Investigator; 8. Ability to provide written, informed consent prior to initiation of any study- related procedures, and ability in the opinion of the Investigator to understand and comply with all the requirements of the study, which includes abstaining from the use of prohibited medications. 9. Subject must present with at least moderate symptomatology, based on having symptoms in the prior 24 hours that were uncomfortable and interfered with daily activities or required treatment other than study drug and having at least one of the following symptoms: cough; fatigue; myalgia; diarrhea; vomiting; nausea; headache; sore throat; nasal congestion; rhinorrhea; loss of taste; loss of smell; fainting; or chills, shivering, and/or sweating. Exclusion Criteria: 1. Women of childbearing potential, or men whose sexual partner(s) is a woman of childbearing potential, who: 1. Are or intend to become pregnant (including use of fertility drugs) during the study; 2. Are nursing (female subjects only); 3. Are not using an acceptable, highly effective method of contraception until all follow-up procedures are complete. 2. Evidence of pre-existing or new-onset organ failure; 3. Evidence of moderate concurrent nervous system, renal, endocrine, or gastrointestinal disease, unrelated to COVID-19 as determined by the Investigator; 4. Evidence of cardiovascular disease with significant arrhythmia, congestive heart failure (New York Heart Association Class IV), unstable angina, cor pulmonale, or symptomatic pericardial effusion, not related to COVID-19 as determined by the Investigator; 5. Required use of vasoactive drug support; 6. History of myocardial infarction in the 6 months prior to the Screening/Baseline/Day 1 Visit; 7. Evidence of current liver disease, not related to COVID-19 as determined by the investigator; 8. History or evidence of active tuberculosis (TB) infection at Screening/Baseline/Day 1 Visit or one of the risk factors for tuberculosis such as but not limited or exclusive to: 1. History of any of the following: residence in a congregate setting (e.g., jail or prison, homeless shelter, or chronic care facility), substance abuse (e.g., injection or non-injection), health-care workers with unprotected exposure to subjects who are at high risk of TB or subjects with TB disease before the identification and correct airborne precautions of the subject or 2. Close contact (i.e., share the same air space in a household or other enclosed environment for a prolonged period (days or weeks, not minutes or hours)) with a person with active pulmonary TB disease within the last 12 months. 9. History of or currently active primary or secondary immunodeficiency; 10. Past or present requirement for oxygen (e.g., nasal cannula, proning, mechanical ventilation and/or supplemental oxygen). 11. Use of any prohibited concomitant medications/therapies over the defined or planned use of any concomitant medications/therapies during the Treatment Period, including specifically: 1. use of ibuprofen or diclofenac 2. use of colchicine 3. use of systemic steroids within 30 days of randomization 4. use of janus kinase (JAK) inhibitors 5. use of off-label agents (e.g., hydroxychloroquine, remdesivir, dexamethasone) and biologic and oral anti-cytokine agents (e.g., current treatment with adalimumab, infliximab, etanercept, golimumab, certolizumab pegol, tocilizumab, sarilumab, anakinra, canakinumab, rilonacept, baricitinib, tofacitinib, or upadacitinib); Note: During the treatment period a patient may meet the criteria for a treatment approved by the FDA specifically for COVID-19 (e.g. remdesivir). In this situation the investigator and medical monitor should confer and take the most appropriate decision for the patient. If possible, the preference would be for the patient to complete the 14 days of dosing before adding on the 2nd treatment. If that is not possible the preference would be for the patient to continue their 14 days on dapansutrile and complete all study related visits. 12. Known history of renal impairment (e.g., calculated glomerular filtration rate [GFR] < 45 mL/min); 13. Evidence of malignant disease, or malignancies diagnosed within the previous 5 years (except for local basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix uteri that has been excised and cured); 14. History of infection or known active infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV); 15. Any other concomitant medical or psychiatric conditions, diseases, or prior surgeries that, in the opinion of the Investigator, would impair the subject from safely participating in the trial and/or completing protocol requirements; 16. Individuals who have been in a chronic care facility in the past 30 days; 17. Individuals who are incarcerated; 18. Participation in any clinical trial and/or use of any investigational product within the immediate 30-day period prior to the Screening/Baseline//Day 1 Visit; or receipt prior to Screening/Baseline/Day 1 Visit or intending to receive during the trial a COVID-19 vaccination. |
