Brief Summary

The overall objective of this study is to efficiently evaluate the clinical efficacy and safety of different investigational therapeutics among adults who have COVID-19 but are not yet sick enough to require hospitalization. The overall hypothesis is that through an adaptive trial design, potential effective therapies (single and combination) may be identified for this group of patients. COVID-19 Outpatient Pragmatic Platform Study (COPPS) is a pragmatic platform protocol designed to evaluate COVID-19 treatments by assessing their ability to reduce viral shedding (Viral Domain) or improve clinical outcomes (Clinical Domain). To be included into the platform, every investigational product will collect data for both Domain primary endpoints. Individual treatments to be evaluated in the platform will be described in separate sub-protocols.

Outcome Measures

Primary Outcomes (1)

• For the Viral Domain: Change in Viral Shedding

  The number of participants who had viral shedding at Day 10 is reported. Change in shedding of SARS-CoV-2 virus through day 10 attained from self-collected nasal swab RT-PCR data after transformation using a referenced standard curve.

  10 days

Secondary Outcomes (8)

• For Clinical Domain: Time-to-sustained-resolution

  28 days

• Time to Viral Cessation

  28 days

• Time to First Resolution

  28 days

• Time to Full Resolution

  28 days

• Indicator of SARS-CoV-2 Related Hospitalizations, ED Visits, or Death in Outpatients With COVID-19 Disease.

Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• \. Outpatient setting
• Age ≥ 18 years and ≤ 80 years at the time of the assessment
• Able and willing to understand the study, adhere to all study procedures, and provide written informed consent
• Initial diagnosis of COVID-19 disease as defined by an FDA-cleared molecular diagnostic assay positive for SARS-CoV-2 with no more than 72 hours from the initial swab used in the diagnosis to the time of commencing informed consent.
• At baseline, at least two symptoms should have mild or higher severity score, where at least one of the mild symptoms is not cough, fatigue, or loss of smell/taste OR at least one symptom has a moderate or higher severity score on the COVID Outpatient Symptom Scale (COSS).
• Participant's COVID-19 related symptom onset occurred within 7 days prior to time of randomization.
• If male, must be sterile, OR agree not to donate semen AND agree to strictly adhere to contraceptive measures during the study and for seven days following the last dose of study medication
• If female, must be unable to bear children, OR ensure that their male partner is incapable of fathering a child, OR, if of childbearing potential will strictly adhere to contraceptive measures during the study and for seven days following the last dose of study medication, and must agree to stop breast-feeding prior to first dose of study drug and through seven days after completing therapy.

You may not qualify if:

• At screening, the participant needs to be admitted to the hospital or is being evaluated for potential admission.
• Previous use of experimental drugs that may be active against COVID-19 in the eyes of the investigators.
• Participant yields a positive urine pregnancy test at screening.
• Participant is using adrenocorticosteroids (except topical or inhaled preparations or oral preparations equivalent to or less than 10 mg of oral prednisone) or immunosuppressive or immunomodulatory drugs (e.g., immunosuppressants, anticancer drugs, interleukins, interleukin antagonists or interleukin receptor blockers).
• NOTE: Treatment of study participants following institutional COVID-19 treatment policies or guidelines, including the use of immunomodulatory medications, is permitted. This excludes treatment with agents that have the potential for direct antiviral activity, including convalescent plasma and NO, and co-enrollment into other clinical studies that evaluate investigational agents for COVID-19.
• Participant has a serious chronic disease (e.g., uncontrolled human immunodeficiency virus \[HIV\], cancer requiring chemotherapy within the preceding 6 months, and/or moderate or severe hepatic insufficiency).
• Has renal insufficiency including severe renal impairment and ESRD and/or requiring hemodialysis or continuous ambulatory peritoneal dialysis (CAPD).
• Has liver impairment greater than Child Pugh A.
• Has a history of alcohol or drug abuse in the previous 6 months.
• Has a psychiatric disease that is not well controlled where controlled is defined as: stable on a regimen for more than one year.
• Has taken another investigational drug within the past 30 days.
• Is deemed by the Investigator to be ineligible for any reason.
• Participant has a history of gout and coagulation disorders.
• Participant has a concomitant bacterial respiratory infection as documented by a respiratory culture with microbiologic growth. NOTE: Participants on empirical antibiotic treatment for possible but unproven bacterial pneumonia, but who are positive for SARS-CoV-2, are allowed in the study.
• Has previously received camostat mesilate within the past 30 days.
