A Phase 2 interventional study of Remdesivir in Respiratory Syncytial Virus (RSV), sponsored by PENTA Foundation. Recruiting at 8 sites in Thailand. Open to participants aged 0 Days to 2 Years. Per ClinicalTrials.gov, last updated 2025-07-23.
Sponsored by PENTA Foundation · Phase 2, Interventional, and Treatment
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.
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.
359 studies on the registry are indexed under Respiration Disorders; 64 are open to participants now.
This study's planned enrollment of 120 is above the median of 69 across 216 interventional studies indexed under Respiration Disorders.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

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.
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.
Drug: Remdesivir
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.
Also known as: VEKLURY®
Safety and tolerability of Remdesivir
Outcome Measures: Occurrence of the following events from the time of randomization until the last study visit: * serious adverse events (SAEs); * adverse events (AEs) of Grade 3 or higher * treatment-related AEs * AEs leading to treatment discontinuation * treatment-related AEs leading to treatment discontinuation * AEs of Grade 3 or higher leading to treatment discontinuation Acceptability of daily remdesivir infusions to children, health care personnel, and caregivers assessed through questionnaires and direct observation.
Time frame: 1 Week
Evaluation of the RSV RNA viral load
