Descrizione dettagliata
Lo scopo di questo studio è valutare la farmacocinetica, la sicurezza e la tollerabilità del farmaco anti-TBC DLM in combinazione con OBR per MDR-TB in bambini con infezione da HIV e bambini non infetti da HIV con MDR-TB.
I partecipanti saranno iscritti a una delle quattro coorti di età: da 12 a meno di 18 anni, da 6 a meno di 12 anni, da 3 a meno di 6 anni o da 0 a meno di 3 anni. Tutti i partecipanti riceveranno DLM dosato in base alla loro fascia di età e peso per 24 settimane.
Le visite di studio avverranno all'ingresso dello studio; Settimane 2 e 4; ogni 4 settimane fino alla settimana 40; e alle settimane 48, 60, 72 e 96. Le visite possono includere esami fisici; prelievo di sangue, urina ed espettorato; radiografie del torace; elettrocardiogrammi (ECG); test dell'udito; valutazioni di aderenza; e questionari di accettabilità.

Acceptability assessments were assessed by Study Staff at study visits and by Participant Caregiver whilst at home.
The participants had the option of taking the study drug either as 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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.
