Hydroxyurea Therapy: Optimizing Access in Pediatric Populations Everywhere

Status Terminated

Clinical Trial Summary

Primary Objective 1. Define the pharmacokinetics of liquid-formulated HU in infants (9 months to <2 years) 2. Assess the relative bioavailability of HU "sprinkles" compared to capsules in children and adolescents (≥2 to 18 years). Secondary Objective: Compare PK parameters in infants versus older children on this study and those from our previous "Pharmacokinetics and Bioavailability of a Liquid Formulation of Hydroxyurea in Pediatric Patients with Sickle Cell Anemia" (NCT01506544) trial. Exploratory Objectives: Capture information regarding the taste of HU sprinkles using palatability questionnaire. This trial is an open label, single center assessment of the pharmacokinetics of two formulations of hydroxyurea (HU) designed to (1) determine the pharmacokinetic profile of a liquid formulation in infants and to (2) determine the bioavailability of "sprinkles", a novel method of administration for older children. The study aims to generate data to facilitate FDA approval for HU in children and potentially validate a new mode of administration ("sprinkles") that will optimize access and adherence for children in the US and globally.

Clinical Trial Description

HOPE18 will be an open label, 2-arm study of HU disposition in 48 children with SCD. In Arm 1, n=18 infants ages 9 months to 2 years will be administered an extemporaneous oral liquid formulation of HU on a single occasion followed by PK sampling. The dose administered will be ~20 mg/kg/day or the infant's usual daily dose. In Arm 2, n=30 children who range in age from 2 to 18 years will be administered HU, both a sprinkle formulation and capsules (Droxia® 200 mg), on two separate occasions separated by at least 1 day but no more than 30 days in a randomized, crossover fashion. The doses of HU on each occasion will be rounded to the nearest 200 mg and will not exceed 35 mg/kg or 2000 mg. We hypothesize that the PK profile of the sprinkle formulation will not differ significantly from the PK profile of Droxia® capsules in children and adolescents ages ≥2 - 18 years of age. Participants in both arms will be followed up to 30 days from receiving last HU dose. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
