Gedetailleerde beschrijving
Het doel van deze studie is het evalueren van de farmacokinetiek, veiligheid en verdraagbaarheid van het anti-tbc-medicijn DLM in combinatie met OBR voor MDR-tbc bij hiv-geïnfecteerde en hiv-niet-geïnfecteerde kinderen met MDR-tbc.
Deelnemers worden ingeschreven in een van de vier leeftijdscohorten: 12 tot minder dan 18 jaar, 6 tot minder dan 12 jaar, 3 tot minder dan 6 jaar of 0 tot minder dan 3 jaar. Alle deelnemers krijgen gedurende 24 weken DLM gedoseerd volgens hun leeftijdsgroep en gewicht.
Studiebezoeken vinden plaats bij aanvang van de studie; Week 2 en 4; elke 4 weken tot en met week 40; en in week 48, 60, 72 en 96. Bezoeken kunnen lichamelijke onderzoeken omvatten; verzameling van bloed, urine en sputum; röntgenfoto's van de borst; elektrocardiogrammen (ECG's); gehoortesten; therapietrouw beoordelingen; en aanvaardbaarheidsvragenlijsten.

Age Effect on Bioavailability DLM
Tijdsspanne: 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
Tijdsspanne: 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.

Dose Effect on Bioavailability DLM
Tijdsspanne: 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.
