Atovaquone for Treatment of COVID-19 : Atovaquone for Treatment of COVID-19

Design of the ATaQ COVID-19 Trial:The purpose of the current study is to accelerate the use of a clinically available therapeutic already FDA-approved for other indications in the setting of pandemic COVID-19 addressing a serious and emergent unmet medical need. In consideration of the information included in this protocol, the overall risks to participants are outweighed by the potential benefits of atovaquone experimental therapy for the treatment of COVID-19. The benefit-risk balance for this study is considered positive.Inclusion Criteria:Diagnosis of COVID-19 by positive RT-PCR requiring hospitalization within 72 hoursAge ≥18 years oldAble to provide informed consent, or (as allowed by IRB), immediate availability of designated legally authorized representative to provide consent by proxyAnticipated hospitalization for >48 hoursExclusion CriteriaPatients who meet any of the following exclusion criteria are not to be enrolled in this study:Participation in any other clinical trial with antiviral activity against COVID-19Breastfeeding womenKnown hypersensitivity to atovaquone or formulation excipientActive treatment with rifampinHIV patients with AIDS requiring treatment for Pneumocystis jirovecii or Toxoplasma gondiiNot expected to survive for 72 hours.>14 days from symptom onsetRandomization:Patients who meet eligibility criteria and volunteer to participate will be randomized in a 2:1 ratio to atovaquone or placebo on Day 1 using computerized randomization. An unblinded investigational pharmacist not otherwise involved in the trial will know treatment assignment and dispense investigational product. As GI absorption of atovaquone increased when taken with food, so we will administer with a meal or snack.Blinding:Double blinding of treatment assignments will be performed in this study, with the study team and patients blinded to treatment assignment.The list of concomitant medications will be assessed only from Day 1 prior to enrollment to Day 15 or discharge, whichever is earlier.Patient Enrollment and Treatment Assignment:Entry into screening does not guarantee enrollment into the study. In order to manage the total study enrollment, the study researchers may suspend screening and/or enrollment at any at any time.Pretreatment Assessments:Screening VisitPatients will be screened within 2 days before randomization and dosing to determine eligibility for participation in the study. Screening will occur under approved HIPAA waiver for research to identify and screen all hospitalized COVID-19 positive patients on a daily basis.Obtain informed consent.After informed consent has been negotiated and the form signed, the following assessments will be performed to determine eligibility requirements as specified in the inclusion and exclusion criteria:Review of focused medical history including the following information (e.g., date of first symptoms, overall symptoms, exposure source, demographics, baseline characteristics), allergies and past medical history.Review and record medications and therapies for the current illnessRecording of vital signs (heart rate, temperature, blood pressure), body weight, and heightDocumentation of respiratory support: Respiratory Rate, Oxygen supplementation: room air, nasal canula, face mask, non-rebreather, high-flow device, mechanical ventilation; and FiO2SpO2 at rest or PaO2Radiographic findingsStudy patients who qualify and volunteer to participate should be immediately consented and randomized. Randomization and initiation of dosing should occur on the same day if possible.Baseline/Day 1 AssessmentsThe following evaluations are to be completed at the Day 1 visit. The investigator must have confirmed eligibility and signing of consent before proceeding with randomization on the Day 1 visit, followed immediately by first dose of investigational product. The assessments can be completed by the patient care team and do not need to be repeated by research personnel. The following assessments must be documented before administering investigational product, using the most recent data available at the time of randomization:Recording of vital signs (heart rate, temperature, blood pressure, body weight, height)Documentation of respiratory status:Respiratory rateOxygen supplementation and FiO2: room air, nasal canula, face mask, non-rebreather, noninvasive ventilation or high flow oxygen devices, mechanical ventilation, or ECMOOxygenation: (SpO2 or PaO2)Radiographic findings (if available)Review AEs and document concomitant medicationsDocument Ordinal Scale at baselineObtain saliva sample and nasopharyngeal swab sample for viral load quantification at day 1 prior to initial doseObtain blood for research sampleDaily Study Assessments (Days 2-15):The following evaluations are to be documented daily from Days 2 - 15 or until discharge whichever comes earlier, using the data recorded at or closest to 12:00 noon each day:Vital signs (heart rate, temperature, blood pressure), body weight (if available).Documentation of respiratory status: Respiratory rate, Oxygen supplementation and FiO2: room air, nasal canula, face mask, non-rebreather, noninvasive ventilation or high flow oxygen devices, mechanical ventilation, or ECMOOxygenation: (SpO2 or PaO2)Radiographic findings (if available)Review of AEs and document concomitant medicationsSaliva sample for COVID-19 RT-PCR every 12 hours (Days 2-8)Saliva sample for COVID-19 RT-PCR once daily (Days 9-15)Additional blood draws for biobanking (Day 3, and 5 only)Clinical Laboratory Assessments:Clinical laboratory assessments will be conducted as clinically indicated and all laboratory testing will be completed by local laboratories. Clinical laboratory data to be captured in the trial database will include serum chemistries, liver function tests, complete blood counts including absolute neutrophil count, hs-CRP, D-dimer, ferritin, IL-6, troponin, NTpBNP.SARS-CoV-2 testing will include RT-qPCR to detect or quantify SARS-CoV-2 or virus sequencing results from saliva (baseline and daily until discharge or death, and 8 days and last day of hospitalization or Day 15 if still hospitalized.Pretreatment and posttreatment samples with detectable SARS-CoV-2 may be sequenced for resistance monitoring of the viral polymerase gene. For all clinical laboratory tests, except those at Day 1, when more than 1 result is available in a calendar day, the value closest to 12:00 noon should be captured in the eCRF. For Day 1 tests, the most recent result before dosing should be used.Physical Examination:No physical examination is mandated by the study protocol beyond the capture of vital signs (heart rate, respiratory rate, temperature, blood pressure, SpO2 at rest or PaO2) as documented clinically.Post-treatment Assessments:Treatment will continue to complete a 10 Day course or until viral clearance is documented, whichever occurs first.Telephone call on Day 15 and 29 for those discharged. The phone call will include a brief survey on symptoms and information on any re-hospitalizations.Final review of AEs and concomitant medication.Vital signs will be captured if still inpatient and the ordinal scale will be assessed..
