PHRU CoV01 A Trial of Triazavirin (TZV) for the Treatment of Mild-moderate COVID-19

• Status: Recruiting
• Trial end date: 2021-12-31
• Target enrollment: 0
• Participant gender: All

Summary

A) Phase II: Early viral responses to triazavirin In hospitalised patients with mild-moderate COVID-19, in addition to standard of care therapy, treatment with triazavirin 250mg three times daily for five days, the slope of increase of the Ct values of serial nasopharyngeal swabs to 12 days after initiation of treatment will be ≥24% higher than in hospitalised patients receiving standard of care treatment only.

B) Phase III: Efficacy of triazavirin to improve clinical outcomes In hospitalised patients with mild-moderate laboratory proven COVID-19, in addition to standard of care therapy, treatment with triazavirin 250mg three times daily for five days will reduce a composite outcome - death; ICU admission or mechanical ventilation; or prolonged duration of admission- by ≥29% when compared to the composite outcome in hospitalised patients receiving standard of care therapy only.

• Phase: Phase 2/Phase 3

Criteria

Inclusion Criteria:

1. Patients ≥18 years of age, who have a clinical presentation suggestive of COVID-19, or who have had a molecular laboratory assay that confirms SARS-CoV-2 infection that was collected prior to the first dose of study treatment.

2. Patients with mild to moderate COVID-19 who need admission and may require oxygen at admission but not yet requiring escalation of oxygen therapy to CPAP, high flow nasal oxygen or intubation. We will not include patients with laboratory confirmation of SARS-CoV-2 who report no symptoms at all.

3. Able to provide own consent

4. Willing to have HIV test - unless already has clinical documentation of HIV infection (as evidenced by a HIV rapid test result during the admission, or any one of the following: a positive HIV ELISA assay; an ART prescription; a pill container for ART with the patient's name; a hard copy or an electronic viral load result that includes the patient's name showing detectable HIV copies; clinical documentation of HIV sero-positivity included in the medical record)

5. Randomisation must occur within 48 hours of first COVID-19 diagnosis during the current illness.

Exclusion Criteria:

1. Women who are pregnant or breastfeeding at the time of enrolment

2. Weight <40kg.

3. Evidence of current liver disease (AST/ALT >3x ULN ; total bilirubin>3xULN or prior history of cirrhosis or other chronic liver disease)

4. Renal dysfunction as evidenced by an estimated glomerular filtration rate (eGFR) <60ml/min, or prior/current diagnosis of chronic kidney disease.

5. Prior receipt of any treatment with putative or proven anti-SARS-Cov-2 activity apart from the following: chloroquine, hydroxychloroquine, or ritonavir/lopinavir initiated no more than 12 hours prior to first receipt of TZV/placebo for this trial. Antiretrovirals initiated prior to admission as treatment for HIV, supportive, steroidal and non-steroidal anti-inflammatory, or anti-pyretic treatments are allowed.

6. Indication for immediate initiation of antiretroviral therapy in HIV-infected patients, who are unable to delay ART initiation or re-initiation until the treatment phase of this study is complete.

7. Permanently lives or works more than 120km from the hospital where recruited

8. Unable to provide own consent

9. In the opinion of either the attending doctor, or a study investigator that the patient is not a candidate for a clinical trial

10. Receipt of anti-epileptic medication, warfarin or TB treatment at the time of recruitment or during the receipt of trial treatment.

11. Enrolled currently in a trial of novel preventive treatment or treatment of SARS-CoV-2.

12. Potential participants who are investigational site staff members, or relatives of a site staff member, or those who are employees of PharmaCentrix involved in the conduct of the trial.
