Descripción detallada
El propósito de este estudio es evaluar la farmacocinética, la seguridad y la tolerabilidad del fármaco antituberculoso DLM en combinación con OBR para la TB-MDR en niños infectados y no infectados por el VIH con TB-MDR.
Los participantes se inscribirán en una de las cuatro cohortes de edad: de 12 a menos de 18 años, de 6 a menos de 12 años, de 3 a menos de 6 años o de 0 a menos de 3 años. Todos los participantes recibirán DLM dosificado según su grupo de edad y peso durante 24 semanas.
Las visitas de estudio se realizarán al ingresar al estudio; Semanas 2 y 4; cada 4 semanas hasta la semana 40; y en las semanas 48, 60, 72 y 96. Las visitas pueden incluir exámenes físicos; recolección de sangre, orina y esputo; radiografías de tórax; electrocardiogramas (ECG); pruebas de audición; evaluaciones de adherencia; y cuestionarios de aceptabilidad.

Periodo de tiempo: Assessments conducted at weeks 2, 8 and 24
|
Acceptability assessments were assessed by Study Staff at study visits and by Participant Caregiver whilst at home.
Participants' dose formulations were not restrictive as at each visit, the participant was given the option of taking the study drug as either a dispersible tablet or tablet formulation.
At a visit, the participant could have been taking a dispersible tablet and at the next visit the same participant could have been taking a tablet formulation.

Age Effect on Bioavailability DLM
Periodo de tiempo: Approximately Week 2
|
Plasma concentrations are used to determine age effect on bioavailability.
The age covariate describes the fold change in bioavailability for each respective age group of 0-1 year and 1-2 years, with participants aged >2 to <18 years used as the reference group.
Study arms were combined for the analysis of age effect.

Age Effect on Fraction Metabolised From Delaminid to DM-6705
Periodo de tiempo: Approximately Week 2
|
Plasma concentrations are used to determine age effect on bioavailability.
The age covariate describes the fold change in bioavailability for each respective age group of 0-1 year and 1-2 years, with participants aged >2 to <18 years used as the reference group.
Study arms were combined for the analysis of age effect.

Dose Effect on Bioavailability DLM
Periodo de tiempo: Approximately Week 2
|
Plasma concentrations are used to determine dose effect on bioavailability.
For doses > 50 mg the bioavailability is described by F=(dose/100)-0.66.
The participants receiving the dose 100 mg are the reference group and the dose effect of doses 15-20mg, 25mg and 50mg on the bioavailability are compared to the reference group and the fold change is presented.
Study arms were combined for the analysis of dose effect.
