Study of Obeldesivir to Treat Nonhospitalized Adults With Acute Respiratory Syncytial Virus (RSV) Infection

Phase 2
Recruiting
Conditions
RSV Infection
Interventions
Drug: Obeldesivir Placebo
Registration Number
NCT06585150
Lead Sponsor
Gilead Sciences
Brief Summary

The goal of this clinical study is to learn more about the study drug, obeldesivir (ODV; GS-5245), and how safe and effective it is in treating nonhospitalized adults with acute respiratory syncytial virus (RSV) infection. The researchers want to see if obeldesivir can help participants' symptoms get better faster.

The primary objectives of this study are to evaluate the efficacy of ODV in reducing the duration of symptoms and to evaluate the safety and tolerability of ODV in nonhospitalized adult participants with acute RSV infection.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Experiencing Treatment-emergent Adverse Events (TEAEs) Through Day 29Up to 29 days
Percentage of Participants Experiencing Laboratory Abnormalities Through Day 29Up to 29 days
Time to Alleviation of Targeted Respiratory Syncytial Virus (RSV) Symptoms as Measured by Respiratory Infection Intensity and Impact Questionnaire (RiiQ) through Day 15Day 1 up to Day 15

The RiiQ symptom scale is a 13-item questionnaire rated on a 4-point scale. Each symptom is rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity.

Percentage of Participants Experiencing Serious Adverse Events (SAEs) and Adverse Events (AEs) Leading to Study Drug DiscontinuationFirst dose date up to Day 60
Secondary Outcome Measures
NameTimeMethod
Time to Sustained Alleviation of Targeted RSV Symptoms as Measured by RiiQ Through Day 15Day 1 up to Day 15

The RiiQ symptom scale is a 13-item questionnaire rated on a 4-point scale. Each symptom is rated on a scale of 0 to 3 where 0=None, 1=Mild, 2=Moderate, and 3=Severe. Higher scores indicated greater severity.

Time to RSV-Related Lower Respiratory Tract Infection (LRTI) Through Day 29Day 1 up to Day 29

RSV-related LRTI will be defined by symptoms (eg, cough, shortness of breath, wheezing, expectoration \[coughing up mucus\]) as assessed by the RiiQ symptom scale.

Time to RSV-Related Hospitalization or all-Cause Death Through Day 29Day 1 up to Day 29

RSV-related hospitalization is defined as ≥ 24 hours of acute care for a reason related to RSV, in a hospital or similar acute care facility, including emergency rooms or temporary facilities instituted to address medical needs of those with RSV.

Time to RSV-Related Medically Attended Visit (MAVs) or all-Cause Death Through Day 29Day 1 up to Day 29
Change from baseline in RSV Viral Load Through Day 3Baseline, Day 3
Change from Baseline in RSV Viral Load Through Day 5Baseline, Day 5
Change from Baseline in RSV Viral Load Through Day 7Baseline, Day 7
Change from Baseline in RSV Viral Load Through Day 10Baseline, Day 10
Change from Baseline in RSV Viral Load Through Day 15Baseline, Day 15
Pharmacokinetic (PK) Parameter: AUCtau of GS-441524Day 1 to Day 5

AUCtau is defined as the area under the concentration versus time curve over the dosing interval.

PK Parameter: Ctrough of GS-441524Day 1 to Day 5

Ctrough is defined as the concentration at the end of the dosing interval

PK Parameter: Cmax of GS-441524Day 1 to Day 5

Cmax is defined as the maximum observed concentration of drug in plasma.
