Trial Outcomes

Recurrence of an Infarct, Defined as a Stroke or a New or Enlarged Silent Cerebral Infarct

The primary end point was the recurrence of infarct or hemorrhage as determined by neuroimaging, clinical evidence of permanent neurologic injury, or both. A new infarct had to meet the criteria for a silent cerebral infarction; an enlarged silent cerebral infarct was defined as a previously identified silent cerebral infarct that increased by at least 3 mm along any linear dimension in any plane on MRI. (NCT00072761)
Timeframe: From study entry to study exit

Percentage of Participants With Dose Limiting Toxic Events

An expected toxicity rate of 20% and acceptable toxicity rate of 30% were used for statistical calculations. After 53 participants at each site complete 3 months of therapy, if ≤ 15 participants have hematologic toxicity there is no early evidence against safety. If ≥ 15 of the initial participants experience toxicity, this is early evidence against safety. Future participants will begin at a lower dose of hydroxyurea (10 ± 2.5 mg/kg), with another 53 participants recruited of the same safety analysis. Upon final analysis of 133 participants at the same starting dose, safety for fixed-dose hydroxyurea can be concluded. (NCT01966731)

Barthel Index (Change From Baseline)

The Barthel Index is a measure of activities of daily living (ADL) and assesses the degree of disability in a particular participant. The index records indicators of independence in terms of the disability caused by impairments, such as those that may be sequelae of stroke. The index was used as a record of what the participant did, not as a record of what the participant could do. Barthel scores range from 0 to 100, with higher scores indicating greater independence in daily living activities (caring for oneself). (NCT00122980)

Liver Iron Content (LIC) Change-from-baseline

LIC change-from-baseline is the second component of the composite primary endpoint. LIC was measured by quantitative liver biopsy at baseline and at 30 months or exit from the study.LIC values were transformed into Log10 values prior to computing the change from baseline. (NCT00122980)

This test is designed to assess both broad and narrow cognitive abilities in children age 4 years and above as well as to measure major aspects of academic achievement in persons aged 2-90 years. Higher scores mean better abilities/achievements. Scaled scores range from 0-100. (NCT00122980)

Occurrence of an Adjudicated Secondary Stroke During the 30-month Treatment Period

Secondary stroke is the first component of the composite primary endpoint and considers the number of participants with recurrent secondary stroke events during 30 months of treatment. Stroke was defined as any clinical event with brain injury due to vascular disease. All neurological events underwent formal stroke adjudication. (NCT00122980)

Pediatric Quality of Life (PedsQL) - Child Report (Change From Baseline)

The PedsQLTM Measurement Model is a modular approach to measuring health-related quality of life (HRQOL) in healthy children and adolescents and those with acute and chronic health conditions. It has a Likert 5-points scale (never to almost always) which were transformed to a 0 to 100 scale based on the PedsQL scoring algorithms, higher scores indicating better quality of life characteristics.

The PedsQL(TM) Measurement Model is a modular approach to measuring health-related quality of life (HRQOL) in healthy children and adolescents and those with acute and chronic health conditions. It has a Likert 5-points scale (never to almost always) which were transformed to a 0 to 100 scale based on the PedsQL scoring algorithms, higher scores indicating better quality of life characteristics. (NCT00122980)

Woodcock-Johnson Test of Cognitive Abilities (WJ-C) and Achievement (WJ-III) (Change From Baseline)-Excluding Verbal

This test is designed to assess both broad and narrow cognitive abilities in children age 4 years and above as well as to measure major aspects of academic achievement in persons aged 2-90 years. Scaled scores range from 0-100. Higher scores mean better abilities/achievements. (NCT00122980)

Difference in TCD Time-averaged Mean Velocity (TAMV) on the Index Side

The primary endpoint for the TWiTCH trial was the difference between the treatment groups of the maximum TCD TAMV on the index side, calculated from a mixed model. The index side is the side with the higher mean (averaged over baseline evaluations) of the maximum (over arteries on that side) TCD time-averaged velocity. Values of the TAMV on the index site were obtained at clinic visits during baseline and during the treatment period. (NCT01425307)
Timeframe: Since the study was terminated early, time frame is from beginning of treatment until end of treatment (up to 24 Months).
