Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key exclusion criteria
* SARS-CoV-2 positive within 28 days of Screening or at Screening following signature of full ICF.
* Clinical evidence of a lower respiratory tract infection, as determined by the Investigator.
* Anticipated need for hospitalization or emergency room care within 24 hours of Screening.
* Receipt of systemic antiviral, antibacterial, antifungal, or antimycobacterial therapy within 7 days of Screening and for the duration of the study
* Awareness of concomitant respiratory infections that are viral (other than RSV), bacterial, or fungal, including systemic bacterial or fungal infections, within 7 days of Screening.
* Frailty scale score =4 at Screening.
* History of chronic liver disease (eg, hemochromatosis, Wilson's disease, alpha-1 antitrypsin deficiency, autoimmune hepatitis, nonalcoholic steatohepatitis, and/or alcoholic liver disease); a history of biliary disease (eg, primary sclerosing cholangitis, cholecystitis, choledocholithiasis); or a history of portal hypertension. A diagnosis of hepatic steatosis (fatty liver) is not exclusionary.
* Heart disease: any congenital heart disease, acute or chronic heart failure, ischemic heart disease, congenital long QT syndrome, or any clinical manifestation resulting in QT interval prolongation.
* Neurological and neurodevelopmental disorders (including disorders of the brain, spinal cord, peripheral nerve, and muscle, eg, cerebral palsy, epilepsy [seizure disorders], stroke, muscular dystrophy, or spinal cord injury).
* Malignant tumor or history of malignancy that may interfere with the aims of the study or a subject completing the study.
* Prior receipt or the subject is waiting to receive a bone marrow, stem cell, or solid organ transplantation.
* Diagnosis of cystic fibrosis.
* Known positive human immunodeficiency virus, active hepatitis A virus infection, chronic hepatitis B virus infection, and/or current or treated hepatitis C virus infection.

* Pregnant or nursing female subjects.
* History of alcohol addiction or current heavy alcohol use defined as: >14 standard drinks per week and/or =4 standard drinks per occasion for males and >7 standard drinks per week and/or =3 standard drinks per occasion for females. A standard drink is 12 oz of beer (5% alcohol), 5 oz table wine (12% alcohol), or 1.5 oz of spirits (40% alcohol).
* Known or suspected, in the opinion of the Investigator, renal disease or renal impairment.
* Twelve-lead ECG demonstrating a QT interval corrected for heart rate according to Fridericia (QTcF) that is >500 msec or other clinically relevant abnormalities as judged by the Investigator at Screening.
* Use of or intention to use excluded or contraindicated medication(s) or supplements, including any medication known to be a moderate or potent inducer or inhibitor of the cytochrome P450 3A4 enzyme, within 14 days prior to Screening and for the duration of the study.
* Receipt of =14 days of systemic immunomodulator therapy (eg, oral corticosteroids) within 3 months of Screening.
* Prior to the first dose of study drug and during study participation, the subject has received any vaccine, investigational agent, or biological product within 30 days or 5 times the half-life, whichever is longer. Note: Influenza vaccination within 7 days of Screening is allowed.
* Use of St John's wort within 28 days prior to the first dose of study drug and for the duration of the study.
