    2. Respiratory failure defined based on resource utilization requiring at least one of the following:

    i. Endotracheal intubation and mechanical ventilation, oxygen delivered by high flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates > 20 L/min with fraction of delivered oxygen ≥ 0.5), noninvasive positive pressure ventilation, extracorporeal membrane oxygenation (ECMO), or clinical diagnosis of respiratory failure (i.e., clinical need for one of the preceding therapies, but preceding therapies not able to be administered in setting of resource limitation) ii. Shock (defined by systolic blood pressure < 90 mmHg, or diastolic blood pressure <60 mmHg or requiring vasopressors) iii. Multi-organ dysfunction/failure

  • Any other clinically significant acute illness unrelated to COVID-19 within seven days prior to first study drug administration
  • Receipt of any experimental treatment for COVID-19 (off-label, compassionate use, or study-related) within the 30 days prior to the time of the screening evaluation
  • Any excluded concomitant medication as described in the ARAKODA package insert [Section 16.1]. Receipt of a COVID-19 vaccine is not exclusionary.
  • Any COVID-19 symptoms which, in the opinion of the investigator, is suggestive of possible requirement to hospitalize within 48 hours of enrollment
  • Positive pregnancy test
  • Have been symptomatic for more than seven days when the first dose would be administered

5. Study Description

Brief Summary
A clinical study to assess the efficacy and safety of oral tafenoquine compared to placebo in patients with mild to moderate COVID 19 disease.
Detailed Description
The TQ 2020_06 study is a double-blind placebo-controlled, Phase 2 clinical trial that plans to enroll approximately 275 patients with mild to moderate infection with COVID-19. Patients will undergo a brief screening period before being randomized to receive either self-administer 200 mg tafenoquine or matching placebo for 10 days. Following the treatment period, patients will have a follow up visit at study Day 28 (28 days after the first dose of study medication). The study's primary efficacy endpoint is proportion of patients with clinical recovery from COVID-19 symptoms on Day 14 in patients with mild to moderate COVID-19 disease compared with placebo.

Planned Interim Analysis and Data Monitoring
Description
Binding futility analysis of primary endpoint will be performed a minimum of 3 weeks after the earlier of [i] 100 pts. randomized or [ii] 6 months has elapsed since randomization of the first pt. in the study. Objective is to determine if tafenoquine increases the proportion of pts. with clinical recovery from COVID-19 symptoms on Day 14 in pts. with mild/moderate COVID-19 disease compared with placebo. Enrolment may be paused by sponsor prior to futility analysis if total number of pts. randomized reaches n=100 and re-initiated by sponsor after completion of futility analysis, if continuing study is determined to be non-futile. Unblinded interim analysis will be conducted by DMC statistician and results will be presented to DMC. If conditional power is less than the predetermined threshold, DMC will recommend terminating enrollment. Sponsor and study team will remain blinded, but will curtail enrollment based on recommendation of the DMC.
