Study of Obeldesivir to Treat Children With Respiratory Syncytial Virus (RSV) Infection
- Registration Number
- NCT06784973
- Lead Sponsor
- Gilead Sciences
- Brief Summary
The goal of this clinical study is to check if obeldesivir (ODV; GS-5245) is safe and well-tolerated by children with respiratory syncytial virus (RSV) infection. It will also look at how well ODV helps reduce the time it takes for children to feel better and for their RSV symptoms to improve.
The primary objectives of this study are: a) to evaluate the safety and tolerability of ODV in pediatric participants with RSV infection; b) To evaluate the efficacy of ODV on time to alleviation of targeted RSV symptoms in pediatric participants with RSV infection.
- Detailed Description
Pediatric participants will be enrolled as follows:
* Cohort 1: Infants and children from 4 weeks postnatal age, weighing ≥ 1.5 kg to \< 40 kg
* Cohort 2: Neonates, either born at term or preterm, weighing ≥ 1.5 kg to \< 6 kg

- History of asthma or recurrent wheezing.
- Neuromuscular disease that affects swallowing.
- Cystic fibrosis.
- Participants who are immunocompromised.
- Alanine aminotransferase ≥ 5 × upper limit of normal (ULN).
- Abnormal renal function.
- Concurrent or previous treatment with other agents with actual or possible direct antiviral activity against RSV, received within 28 days or within 5 half-lives, whichever is longer, prior to randomization.
- Received palivizumab within 100 days, or nirsevimab within 1 year, or other RSV specific monoclonal antibody within 5 half-lives of the antibody, prior to randomization.
- Participant whose mother received RSV vaccination during pregnancy and who is < 1 year old prior to randomization.
Note: Other protocol defined Inclusion/Exclusion criteria may apply.

- Primary Outcome Measures
Name Time Method Percentage of Participants Experiencing Treatment-emergent Adverse Events (TEAEs) Through Day 28 First dose up to 28 days Percentage of Participants Experiencing Grade 3 or 4 Treatment-emergent laboratory abnormalities by Day 28 First dose up to 28 days Time to Alleviation of Targeted RSV Symptoms by Day 28 First dose up to 28 days
- Secondary Outcome Measures
Name Time Method Pharmacokinetic (PK) parameter AUCtau of ODV metabolite, GS-441524 Day 1 to Day 5 AUCtau is defined as the area under the concentration versus time curve over the dosing interval.
PK parameter Cmax of ODV metabolite, GS-441524 Day 1 to Day 5 Cmax is defined as the concentration at the end of the dosing interval.
PK parameter Ctrough of ODV metabolite, GS-441524 Day 1 to Day 5 Ctrough is defined as the concentration at the endo of the dosing interval.
Change From Baseline in RSV Nasal Swab Viral Load at Day 5 Baseline, Day 5 Time to Sustained Alleviation of Targeted RSV Symptoms by Day 28 First dose up to 28 days Time to Resolution of Targeted RSV Symptoms by Day 28 First dose up to 28days Assessment of Palatability and Acceptability Scores of Age-specific Formulation as Assessed by Caregiver at Days 1 and 5 Day 1 to Day 5 Palatability and acceptability assessed by a numeric response between numbers 1-5. Higher scores indicate better palatability and acceptability.
