Are you experiencing symptoms of RSV?
This clinical research study is looking at the safety and effectiveness of an experimental treatment for Respiratory Syncytial Virus (RSV), a contagious virus that can cause infections in the lungs and air passages.
The purpose of this study is to learn about the safety and effects of sisunatovir. Sisunatovir is being studied for the possible treatment of Respiratory Syncytial Virus (RSV). RSV is a virus that causes lung infections with cold-like symptoms, but it can cause severe illness in some people. Sisunatovir is studied in adults:
- who are not admitted to the hospital and
- who have high chances of having a severe illness from RSV infection.
This study is seeking participants who:
- Are confirmed to have RSV.
- Have symptoms of a lung infection.
- Are 18 years of age or older.
- Have one or more of the following which increases the chances of RSV illness:
- A long-term lung disease.
- heart failure.
- a condition that weakens the immune system.
- Are 65 years of age or older and do not have any of the conditions above
Half of the participants in this study will receive sisunatovir. The other half will receive a placebo for 5 days. Placebo looks same like the study medicine but does not have any medication. Both sisunatovir and placebo will be taken by mouth. The study will compare the experiences of people receiving sisunatovir to those of the people who do not. This will help decide if sisunatovir is safe and effective.
Participants will attend about 8-10 study visits over 5 weeks. During this time, they will have:
- visits at the study clinic,
- blood work,
- swabs of the nose,
- questionnaires,
- a follow-up phone call.
Would you like to take part?
As a volunteer in a research study, you will receive study-related medical care from the study doctor and regular follow up of your condition to monitor the effectiveness of the care you will receive. The results of this research will be used to find out if the investigational medication being studied will be of benefit to other patients with RSV, and whether it will be made widely available in Canada. Study volunteers are an important part of moving medical care forward.
You may qualify to participate in this study if you:
- Are aged 18 years or older at screening.
- Have a diagnosis of RSV infection collected within 5 days prior to randomization.
- Have any new onset or worsening (if present chronically) of at least one of the following signs and/or symptoms consistent with a viral acute respiratory infection (ARI), within 5 days prior to randomization: nasal congestion, nasal discharge, sore throat, cough, sputum production, shortness of breath, or wheezing.
- Have at least 1 of the following characteristics or underlying medical conditions:
- 65 years of age or older
- Chronic lung disease,
- Heart failure,
- Immunosuppressive disease/condition or immune-weakening medication
You may not qualify to participate in this study if you:
- Have any medical or psychiatric condition that may increase the risk of study participation or, in the investigator’s judgment, make the participant inappropriate for the study or interfere with the evaluation of response to the study intervention.
- Have a diagnosis of viral respiratory infections other than RSV including influenza and SARS-CoV-2
- Have a current need for hospitalization or anticipated need for hospitalization for any reason to provide inpatient/acute care within 24 hours after randomization
- Have any known history or risk factors for QT prolongation or Torsades de Pointes or congenital deafness, family history of long QT syndrome or unexplained sudden death, or a standard 12-lead ECG with QTcF ≥450 ms
- Have hypersensitivity to or other contraindication to any of the components of the study interventions, as determined by the investigator
There are other eligibility requirements that the study doctor will review. Only the study doctor can finally determine whether you are eligible to participate in the study or not.
