CTTI Recommendations on Pediatric Antibacterial Development
The Clinical Trials Transformation Initiative (CTTI) has released new recommendations to streamline and improve pediatric trials in antibacterial drug development. Regarding pediatric drug development planning, CTTI recommends that sponsors engage with FDA to begin pediatric studies as early in drug development as possible to ensure a clear understanding of FDA requirements. Also, it says sponsors should consider doing this earlier in drug development than is current practice (for example, while Phase 2 adult trials are underway). And sponsors should consider initiating pediatric pharmacokinetic studies, especially in the older cohort of children, concurrently with adult Phase 3 trials when appropriate.
On trial protocol design and development, CTTI recommends that sponsors minimize the burden of participation for patients, their caregivers and study sites. “During the design and development of the protocol, obtain the input of stakeholders who will be affected by implementation of the trial(e.g., nurses, study coordinators, parents, patients, clinicians, site investigators),” it says. Also, sponsors should identify barriers that will affect trial efficiency and enrollment, including visit windows, invasive testing, endpoint timing, and length of follow-up.
Additionally, CTTI says sponsors should “streamline data collection to include only that which is relevant to the goals of the trial.” It says data collection should be focused on pre-specified, relevant outcomes, which should be primarily safety and PK, with efficacy endpoints as appropriate. “When efficacy in children can be extrapolated based on the demonstration of efficacy in adults, collection of efficacy data can be streamlined in the safety and PK studies,” CTTI says.
