E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate efficacy of rilematovir compared to placebo with respect to the time to resolution of respiratory syncytial virus (RSV) lower respiratory tract disease (LRTD) symptoms. |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the effect of rilematovir as compared to placebo: 1) with respect to the incidence of post baseline RSV-related complications; 2) on medical resource utilization (MRU) with respect to respiratory therapeutic interventions associated with RSV-related disease progression; 3) on MRU with respect to medically attended visits associated with RSV-related disease progression; 4) on the overall RSV-related disease progression; 5) on the clinical course of RSV infection; 6) Health-Related Quality of Life; 7) on MRU. - To evaluate the: 1) safety and tolerability of rilematovir; 2) the antiviral effect of rilematovir as measured by RSV viral load in bilateral nasal mid-turbinate swab samples by quantitative reverse transcription polymerase chain reaction assay; 3) emergence of mutations in the viral genome potentially associated with resistance to rilematovir; 4) pharmacokinetics of rilematovir. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. 18 to 85 years of age. 2. Presentation to the healthcare facility with symptoms suggestive of a diagnosis of acute RSV infection and have at least any 2 symptoms of LRTD. 3. Tested positive for RSV infection using a molecular-based diagnostic assay or on a respiratory tract sample. 4. Participants must have at least one high-risk condition that predispose them to RSV-related disease progression. 5. Randomized to study intervention treatment within 72 hours after onset of any of the RSV symptoms or worsening of pre-existing symptoms. 6. Not be hospitalized during screening. |
|
E.4 | Principal exclusion criteria |
1. History of or concurrent disease or clinically significant findings during screening or medical history, physical examination, laboratory testing, vital signs, ECG recording, for which, in the opinion of the investigator, participation would not be in the best interest of the participant. 2. Any condition that could prevent, limit, or confound the protocol-specified assessments. 3. Known allergies, hypersensitivity, or intolerance to rilematovir or to any of the excipients of rilematovir or placebo formulation. 4. Participants who are considered by the investigator to be immunocompromised within the past 12 months, whether due to underlying medical condition or medical therapy.
