What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 600 participants in total. It began in 2020-07-03 with a primary completion date of 2027-03-31.

Brief Summary

The AGILE platform master protocol allows incorporation of a range of identified and yet-to-be-identified candidates as potential treatments for adults with COVID-19 into the trial. Candidates will be added into the trial via candidate-specific trial (CST) protocols of this master protocol as appendices. Having one master protocol ensures different candidates are evaluated in the same consistent manor and opening up new trials for new candidates is more efficient. Inclusion of new candidates will be based on pre-clinical data, evidence in the clinical setting and GMP capabilities.

Eligibility Criteria

Master Protocol Inclusion Criteria: 1. Adults (≥18 years) with laboratory-confirmed\* SARS-CoV-2 infection (PCR) 2. Ability to provide informed consent signed by study patient or legally acceptable representative 3. Women of childbearing potential (WOCBP) and male patients who are sexually active with WOCBP must agree to use a highly effective method of contraception (as outlined in the protocol) from the first administration of trial treatment, throughout trial treatment and for the duration outlined in the candidate-specific trial protocol after the last dose of trial treatment * If any CSTs are included in the community setting, the CST protocol will clarify whether patients with suspected SARS-CoV-2 infection are also eligible. Standard additional criteria that may be applied per CST protocol: Group A (severe disease) 4a. Patients with clinical status of Grades 4 (hospitalised, oxygen by mask or nasal prongs), 5 (hospitalised, on non-invasive ventilation, or high flow oxygen), 6 (hospitalised, intubation and mechanical ventilation) or 7 (ventilation and additional organ support - pressors, renal replacement therapy (RRT), extracorporeal membrane oxygenation (ECMO)), as defined by the WHO clinical severity score, 9-point ordinal scale. Group B (mild-moderate disease) 4b. Ambulant or hospitalised patients with the following characteristics peripheral capillary oxygen saturation (SpO2) \>94% RA N.B. The CST protocol inclusion criteria will take precedence over the master protocol inclusion criteria. CST-2 Inclusion Criteria: For the purpose of the EIDD-2801 candidate-specific trial the following inclusion criteria have been amended from the Master protocol to: 1\. Male or female ≥ 60 years old or ≥50 years old with at least one well controlled comorbidity: cardiovascular disease, chronic lung disease (e.g. COPD, or pulmonary hypertension), immune deficiency (taking the equivalent of 20 mg prednisone daily, chemotherapy, or immune modulating biologic therapies), diabetes (treated with insulin or oral medications), BMI≥30, or hypertension requiring medication with laboratory confirmed SARS-CoV-2 infection (PCR) . 3\. Women of childbearing potential (WOCBP) and male patients who are sexually active with WOCBP must agree to use two effective methods of contraception, one of which should be highly effective (as outlined in the protocol). For women, from the first administration of trial treatment, throughout trial and up to 50 days after the last follow up visit (50 days after day 29) and for men with female partners of child bearing potential, from the first administration until 100 days after last follow up visit (100 days after day 29). 4\. Group B (mild-moderate disease): Ambulant with the following characteristics peripheral capillary oxygen saturation (SpO2) \>94% RA (NB this differs to the Master Protocol which also includes hospitalised patients in this group). Additional criteria specific to this candidate are: 5\. Has signs or symptoms of COVID-19 that began within 5 days of the planned first dose of study drug. 6\.

Criteria 3 has been amended from the Master Protocol to: Women of childbearing potential (WOCBP) and male participants who are sexually active with WOCBP must agree to use a highly effective method of contraception (as outlined in section 5.5 of the Master Protocol) for the duration of the treatment and for six weeks following the last dose. Additional criteria specific to CST-8 are: * Initial onset of COVID-19 signs/symptoms within 5 days prior to the day of randomisation and at least 1 of the current specified COVID-19 signs/symptoms (listed on the NHS website) present on the day of randomisation * Is willing and able to comply with all study procedures and attending clinic visits CST-9a Inclusion Criteria: For the purpose of CST-9a, criteria 1 has been amended from the Master Protocol to: 1. Adults (\>/= 18 years of age) with a positive SARS-CoV-2 lateral flow test on screening or Day 1, who are at high risk (as defined in UK DHSC criteria) of progressing to severe COVID-19 disease, within 3 days of symptom onset, with at least one symptom of COVID-19 infection present on the day of randomization and are with mild- moderate disease severity at enrolment.
