-
Adolescents should be included in adult trials or adolescent trials should be conducted in parallel with adults unless scientifically justified.
-
Studies of medicines across the paediatric spectrum of ages/weights should be conducted in parallel rather than in serial age-staggered approach, taking into account for example the pharmacological characteristics of the particular medicinal product, e.g. specific safety or drug disposition factors which may warrant a different approach.

Pharmacokinetic (PK) and safety information in paediatric patients will be needed to support the appropriate dose for treatment of children.
-
Adolescents with pulmonary TB can be included in phase 3 clinical trials, if appropriate.
-
Paediatric patients can be enrolled in trials if sufficient safety and antimycobacterial activity data in adults are available and appropriate dosing regimens have been characterized.

Studies of drugs across the paediatric spectrum of ages/weights can be conducted in parallel rather than sequentially unless there is a specific safety or pharmacokinetic properties that warrants a different approach.
-
Paediatric development plans for new TB medicines could include children living with HIV and other common co-infections provided there are no safety or drug-drug interaction issues.
-
Cohorts for paediatric studies can be defined based on chronological age or weight-based criteria, particularly for oral drugs.
