Comparing Standard Dose with Precision Dose for patent ductus arteriosus
Official title: Precision Dosing of Oral Ibuprofen for PDA, A Pilot RCT
Model Informed Precision Dosing of Oral Ibuprofen for Treatment of Persistent Patent Ductus Arteriosus: A Pilot Randomized Controlled Feasibility Trial
- Phase 2
- 2 groups
- One site, in Hamilton
- Recruiting
Interventions
- Medication
Standard Dose - Ibuprofen oral suspension
Standard dosing administers ibuprofen without adjustments, starting with an initial loading dose followed by two maintenance doses at 24-hour intervals: 10/5/5 mg/kg for infants aged ≤72 hours, and 20/10/10 mg/kg for those \>72 hours old.
- Medication
Precision Dose - Ibuprofen oral suspension
Precision Dosing (Model-Informed Precision Dosing - MIPD): Begins with the same initial loading dose as the Standard Dosing arm, with subsequent doses adjusted based on a Bayesian forecasting model that integrates real-time PK and echocardiographic data.

About This Trial
Newborns born early are at risk for a serious health problem called patent ductus arteriosus (PDA). PDA is a passageway between heart and lung that can cause life-threatening complications such as bleeding in the brain or even death if it remains open and large. When closure of PDA is needed, doctors make every attempt to do it as soon as possible. Ibuprofen is the best drug to close the PDA, but it only works for 50% of small newborns. The investigators have shown before that small newborns handle ibuprofen differently and the amount of active ibuprofen that reaches their blood can be very unpredictable. Studies have shown if enough ibuprofen reaches the body, it can close the PDA. Therefore the investigators designed this study to see whether it is possible to give each newborn the right amount of ibuprofen that their body needs to close the PDA. The investigators will compare two ways to give ibuprofen in a small number of newborns: 1 - standard amount of ibuprofen to everyone, which is the usual care or 2 - ibuprofen doses that will be changed based on how much active ibuprofen has reached the body and how well the newborn's PDA is closing. The investigators will then compare the number of PDAs closed in each group and closely monitor any possible challenges for this new practice. By doing this project, the goals can be summarized as below: A. Primary goal: To determine if it is feasible to successfully run a larger study in the future. B. Secondary goals 1. To assess how well and how safely the personalized (MIPD) method works, using a tool called WAPPS-PDA to guide dosing. 2. To compare the effectiveness and safety of the personalized method with standard ibuprofen dosing. 3. To identify drug levels in the blood (Cmin, AUC0-24, AUC0-72) that are associated with complete, partial, or no response to treatment.
