AGILE (Early Phase Platform Trial for COVID-19)

• Status: Recruiting
• Trial end date: 2022-04-30
• Target enrollment: 0
• Participant gender: All

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 determined by the AGILE Scientific Advisory Board based on pre-clinical data, evidence in the clinical setting and GMP capabilities.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: University of Liverpool
• Collaborators: Lancaster University; Liverpool School of Tropical Medicine; Liverpool University Hospitals NHS Foundation Trust; University of Cambridge; University of Southampton
• Treatments: Nitazoxanide

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. Is in generally good health (except for current respiratory infection) and is free of uncontrolled chronic conditions.

7. Is willing and able to comply with all study procedures and attending clinic visits through the 4th week.

8. Has someone, aged ≥ 16 living in the same household during the dosing period.

Master Protocol Exclusion Criteria:

1. Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) >5 times the upper limit of normal (ULN)

2. Stage 4 severe chronic kidney disease or requiring dialysis (i.e., estimated glomerular filtration rate <30 mL/min/1.73 m^2)

3. Pregnant or breast feeding

4. Anticipated transfer to another hospital which is not a study site within 72 hours

5. Allergy to any study medication

6. Patients taking other prohibited drugs (as outline in CST protocol) within 30 days or 5 times the half-life (whichever is longer) of enrolment

7. Patients participating in another CTIMP trial

N.B. The CST protocol exclusion criteria will take precedence over the master protocol exclusion criteria.

CST-2 Exclusion Criteria:

Additional criteria specific to this candidate are:

8. Has a febrile respiratory illness that includes signs of pneumonia, or requires hospitalization, oxygenation, mechanical ventilation, or other supportive modalities.

9. Has a platelet count less than 50x10^9/L, or lymphocytes less than 0.2x10^9/L, haemoglobin less than 10 g/dL, or has a disorder of the hematologic system including anaemic disorder or other blood dyscrasia, cancer of the hematologic system, history of bone marrow transplant, or other significant hematologic disease at screening.

10. Is experiencing adverse events or laboratory abnormalities that are Grade 3 or above based on the CTCAE scale.

11. Has clinically significant liver dysfunction or renal impairment.

12. Has history of Hepatitis C infection or concurrent bacterial pneumonia.

13. Has received an experimental agent (vaccine, drug, biologic, device, blood product, or medication) within 30 days prior to the first dose of study drug.

14. In the opinion of the investigator, has significant end-organ disease as a result of relevant comorbidities: chronic kidney disease, congestive heart failure, peripheral vascular disease including diabetic ulcers.

15. Has a SaO2<95% by oximetry or has lung disease that requires supplemental oxygen.

16. Has any condition that would, in the opinion of the investigator, put the patient at increased risk for participation in a clinical study.
