Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

THAI-CARES RSV Study is a Phase II, open-label, multicenter, randomized controlled trial with a two-arm, parallel-group design. The study aims to assess the safety, efficacy, and acceptability of a five-day course of Remdesivir (VEKLURY®) in children under two years of age who are hospitalized with confirmed respiratory syncytial virus (RSV) infection, as determined by either a rapid antigen test or RT-PCR. The primary objectives include evaluating the treatment's safety profile, its ability to significantly reduce RSV replication, and its overall acceptance in this patient population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An overall target of 120 participants will be involved in the study. Eligible participants will be randomized (1:1) to receive ARM 1: Standard of care alone (control arm). ARM 2: Remdesivir in combination with the standard of care. Remdesivir will be administered by intravenous infusion every 24 hours for five (5) consecutive days. Each participant will be followed during hospitalization plus 7-10 days after Day 6\* for final visit.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard of care (control arm).

Standard of care treatments will be delivered according to local practice at each hospital. The standard of care for lower respiratory tract infection includes oxygen therapy as needed, bronchodilators, intravenous fluids, in some cases the use of steroids, antibiotics and any treatment for underlying disease.

Group Type NO_INTERVENTION

No interventions assigned to this group

Intervention arm

Remdesivir will be used in combination with the standard of care. Remdesivir will be administered by intravenous infusion every 24 hours for five (5) consecutive days with a dosage based on the participant's weight at the time of the randomisation.

Group Type EXPERIMENTAL

Remdesivir

Intervention Type DRUG

Remdesivir (RDV) has shown potent antiviral activity against RSV A in an animal model. Remdesivir has been also shown to be a safe treatment option in pediatric patients hospitalized with COVID-19. Based on previous clinical evidence and preclinical data, to address the unmet medical need for safe and effective RSV therapy, this study is being conducted to investigate remdesivir in infants and children (aged 0 days to \<2 years) as a potential treatment for RSV infection.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Signed informed consent from parents/caregivers
* Aged 0 to \<2 years
* Weighing at least 2.0 kg
* Onset of RSV associated-symptoms within 1 week of screening
* Confirmed\* with RSV infection (by rapid antigen test or RT PCR)
* Hospitalized children fulfilling at least two of the following three RSV disease severity criteria:

* Inadequate oral feeding
* Inadequate oxygen saturation (peripheral capillary oxygen saturation \[SpO2\] \<95% on room air or requiring oxygen supplementation to maintain SpO2 ≥95%)
* Signs of respiratory distress (respiratory rate of ≥60 breaths per min for children aged up to 1 year, or ≥40 breaths per min for those older than 1 year, or accessory respiratory muscles use \[subcostal, intercostal, or suprasternal retraction\], or both)

Exclusion Criteria

* Preterm infants (gestational age at birth less than 37 weeks) who are aged \<56 days
* Being hospitalized for other clinically relevant concurrent conditions (except for risk factors for severe RSV, e.g., cardiac disease, pulmonary disease, genetic disease, and prematurity)
* Concurrent treatments with other agents with actual or possible direct antiviral activity against RSV \<24 hours prior to study drug dosing (e.g. ribavirin)
* ALT or AST \> 5 × ULN
* eGFR \<30 mL/min/1.73m2 using the Schwartz formula if aged ≥1 year; or if aged \<1 year based on a creatinine value cut off dependent on chronological age
* Any major congenital renal anomaly if \<28 days
* Apgar score \< 5 when last recorded if age \<24 hours
* Known hypersensitivity to the study drug, the metabolites, or formulation excipient.
* On renal replacement therapies (e.g., intermittent hemodialysis, peritoneal dialysis, continuous renal replacement therapy)
* Any condition that, in the opinion of the site investigator, would make participation in the study unsafe for the child, or comprise the study objectives
