Population Pharmacokinetics of Terbinafine in Children With Tinea Capitis
China60 participantsStarted 2021-06-15
Plain-language summary
The goal of this observational study is to characterize the population pharmacokinetics (PPK) of terbinafine in pediatric patients with tinea capitis, evaluate its efficacy and safety, and identify covariates affecting drug disposition in Chinese children aged 2-18 years diagnosed with tinea capitis and treated with oral terbinafine. The main questions it aims to answer are:
What are the terbinafine pharmacokinetic parameters (e.g., AUC, CL, V) in children with tinea capitis, and how do they differ from adult values? Which covariates (e.g., age, body weight, CYP enzyme activity, renal function) significantly influence inter-individual variability in terbinafine PK parameters? What is the clinical efficacy (based on TSSS reduction and mycological cure rate) and safety profile of terbinafine in this pediatric population?
Participants will:
Undergo oral terbinafine treatment according to weight-based dosing (62.5-250 mg daily).
Concentration determination is carried out using the opportunistic sampling method.
Complete clinical assessments (TSSS scoring) and mycological examinations (microscopy/culture) at baseline and follow-up visits.
Undergo routine laboratory tests (liver/kidney function, hematology) to monitor safety.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is focused on measuring how terbinafine moves through children's bodies rather than testing whether it works — does that mean my child would be receiving a treatment that's already used for tinea capitis, and what would the blood sampling schedule actually look like for them?
2Since this study is measuring drug concentration and how quickly the body clears terbinafine, would my child need extra blood draws beyond what's typical for standard treatment, and how many times would we need to come in?
3The trial is listed as 'Phase NA,' which suggests it's a pharmacokinetics study rather than a traditional drug efficacy trial — does that mean the researchers are trying to figure out the right dosing for children specifically, and is the current dosing my child would receive already considered safe?
4Would my child receive the same terbinafine treatment they'd get outside of this trial, or are there differences in how it's given, and could we discuss whether standard care outside the study might be just as good an option for treating their tinea capitis?
5Because this study is collecting data on how terbinafine is processed in children's bodies, what happens if the drug levels measured in my child turn out to be outside the expected range — would their dose be adjusted during the study?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
