Perinatal Arterial Stroke: A Multi-site RCT of Intensive Infant Rehabilitation (I-ACQUIRE) (I-ACQUIRE)

May 27, 2026 updated by: Sharon Ramey, Virginia Polytechnic Institute and State University
This is a Phase III clinical trial to compare the efficacy of two dosages of a new infant rehabilitation protocol - I-ACQUIRE - to usual and customary forms of infant rehabilitation in infants who experienced Perinatal Arterial Stroke (PAS).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The proposed study is a Phase III trial powered to determine efficacy of two different doses of I-ACQUIRE for children 8 to 36 months old with PAS and hemiparesis. The design is a prospective Randomized Controlled Trial (RCT) in which 216 children will be randomly assigned to one of 3 treatment groups (N=80 per group): 1) Moderate Dose I-ACQUIRE (3 hrs/day, 5 day/wk X 4 wks), 2) High Dose I-ACQUIRE (6hrs/day, 5 days/wk X 4 wks), or 3) Usual and Customary Treatment (U&CT). I-ACQUIRE will be delivered by protocol-trained therapists and monitored weekly for dosage and treatment fidelity; U&CT will be provided by community therapists with dosage and approaches documented weekly. All primary and secondary efficacy outcomes rely on blinded assessments at baseline, end of treatment, and 6 mos post-treatment. Exploratory outcomes and supplemental clinical measures may provide valuable additional data about development and health in this sample of children with PAS.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

8 months to 3 years (Child)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in Emerging Behaviors Scale (EBS) Score
Time Frame: Both immediately after treatment (within 7 days) and 6 months (plus or minus 2 months) post-treatment
The primary efficacy is measured by the Emerging Behaviors Scale (EBS) that counts the number of upper extremity skills on the hemiparetic side that the child displays (from 0 to 30). The source for observation comes from a battery of standardized age-appropriate neuromotor assessment tools (Gross Motor Function Measure-66, The Bayley III Fine and Gross Motor scales, unilateral skills during the Mini AHA) and independent observational coding of the videotaped assessment session with supplemental parent ratings on the Infant Motor Activity Log and daily skills on the MacArthur-Bates Communicative Development Inventory. A favorable outcome is defined as a gain of ≥7 new EBS skills above the child's baseline (pre-treatment) score. The EBS requires evidence of each skill from at least two independent sources.
Both immediately after treatment (within 7 days) and 6 months (plus or minus 2 months) post-treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in Bilateral Use of the Hemiparetic Upper Extermity based on the Mini-Assisting Hand Assessment (Mini-AHA) play assessment
Time Frame: Both immediately after treatment (within 7 days) and 6 months (plus or minus 2 months) post-treatment
The secondary efficacy outcome is measured by increases in the use of the hemiparetic upper extremity while engaged in bilateral activities during the interactive play session of the Mini-AHA. Each item is scored on a 4-pt scale where the points are behaviorally anchored and adjusted for the child's age range. Raw scores are converted into a summary Logit score (0 to 100) based on Item Response Theory analyses, indicating the relative difficulty and sequence in which certain levels of performance appear. For this metric, higher scores are considered better.
Both immediately after treatment (within 7 days) and 6 months (plus or minus 2 months) post-treatment
