Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 85 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • All study participants will be community-dwelling adults with aphasia.
  • Both Veterans and non-Veterans who are able to arrange daily transportation to and from the campus of the VA Pittsburgh Healthcare System (VAPHS), and who do not require housing, may be eligible to be study participants.

  • PIRATE participants are Veterans who are referred nationally to VAPHS.
  • Aphasia diagnosis is provided by the referring medical provider, based on performance on standardized aphasia-assessment measures, and will be verified by PIRATE staff prior to enrollment. Diagnosis will be based on clinical impression and performance on the Comprehensive Aphasia Test (CAT).

  • Lack of physical independence which would interfere with their ability to be present on the VAPHS campus
  • History of progressive neurological disease

  • Inability to tolerate intensive treatment as determined by previous therapy experiences and tolerance of the intensive initial evaluation (2 days of testing)
Show all 14Show fewer
  • In addition, participants who are enrolling in the study through the PIRATE program have the following exclusion criteria apply:
  • Inability to carry out activities of daily living necessary for self-care as determined by an occupational therapy assessment prior to program entry
  • Lack of physical independence
  • History of significant mood or behavioral disorder that is not currently stable/medically managed

About this study

This study examines aphasia treatment response among Veterans and non-Veterans living with aphasia. It seeks to identify cognitive and neural factors which are predictive of positive response to treatment targeting naming impairments in aphasia. It also examines the dose-response relationship for naming treatment. More broadly, it seeks to determine who aphasia therapy works best for, and how much aphasia therapy is sufficient to achieve positive treatment response.

Read the detailed description

Language and communicative impairments following stroke (aphasia) affect more than 30% of stroke survivors, with an incidence of over 180,000 new cases annually. The consequences of aphasia are far reaching and can affect psychosocial adjustment, family role participation, vocational opportunities, and the ability to function independently in society. Recent estimates suggest that VHA outpatient clinics see 2000 new cases of aphasia each year, meaning that approximately 20,000 enrolled VHA patients and 100,000 United States Veterans are currently living with the condition. In response to this need, the VA Pittsburgh Healthcare System Geriatric Research, Education, and Clinical Center (GRECC) initiated the Program for Intensive Residential Aphasia Treatment and Education (PIRATE) in January 2009. PIRATE is a clinical demonstration project that provides approximately 100 hours of cognitive-linguistically oriented aphasia treatment to community dwelling Veterans over a 4-week period. PIRATE currently serves 18 Veterans per year in bi-monthly sessions. Resource limitations associated with PIRATE and aphasia treatment in general require that treatments be offered in the most cost-effective doses to those Veterans most likely to benefit from them.

This treatment-effectiveness research study addresses these issues by examining the dose-response relationship for semantically-oriented naming treatment, and identifying cognitive, psycholinguistic and neuroanatomical predictors of treatment success. Study participants (n=60, over a 4-year period) will be recruited nationwide from Veterans enrolled in PIRATE. They will have their naming performance measured prior to PIRATE entry, during each week of treatment, and at program exit/follow-up. A battery of cognitive measures and structural magnetic resonance images of their brains will also be collected prior to treatment. Participants' performance on trained and untrained lexical items and a standardized measure of naming performance will be compared across time intervals to specify the therapy amounts for which maximum treatment benefits are achieved. Their treatment outcomes will also be correlated with specific cognitive test scores and the location and extent of their brain lesions to identify cognitive and neurological markers predictive of positive treatment response. Treatment response will also be compared across participants with different psycholinguistic profiles, to determine which groups of patients show greatest benefit from semantically-oriented naming treatment.

This study should provide answers to two interlocking questions: for whom is aphasia therapy most effective, and how much of it is needed to optimize treatment outcomes. These answers have the potential to set transformative new standards for how aphasia treatment is delivered within VHA and to stroke survivors with aphasia more broadly.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Naming therapyBehavioural

    Also called Semantic feature analysis

    Participants will receive behavioral therapy which is designed to stimulate semantic (meaning) representations which are required for successful naming (word production). Therapy will be administered for 4 weeks on an intensive schedule (5 days a week, approximately 4.5 hours per day).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Philadelphia Naming Test Score

    The Philadelphia Naming Test is a performance-based measure commonly used to assess naming (word production) ability among adults with aphasia. Participants are shown 175 pictures of common objects and asked to name each stimulus item within 30 seconds. Score range is from 0 to 175 (number out of 175 items that were correctly named), with higher scores representing better performance. Change in PNT score from entry to exit is the primary study outcome. Mean PNT change score measures treatment-related changes in naming ability.

    Measured: Baseline (at study entry) to the day after completion of intervention (after 4 weeks of behavioral therapy).

Secondary outcomes (1)
  1. Change From Baseline on Comprehensive Aphasia Test Modality Mean T-Score

    The Comprehensive Aphasia Test (CAT) is a performance-based measure of language processing across multiple language domains commonly used to assess language-processing ability among adults with aphasia. The CAT Modality Mean T-Score represents an measurement of overall language-processing ability (aphasia severity). Scores are on a T-score scale (mean score 50, 2 SD range from 30 to 70), with higher scores representing better performance. Change in CAT score from entry to exit (secondary outcome) measures treatment-related changes in overall aphasia severity.

    Measured: Baseline (at study entry) to the day after completion of intervention (after 4 weeks of behavioral therapy).

The record says: finished, as of the sponsor's last update on 4 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Nov 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Philadelphia Naming Test Score (time frame: Baseline (at study entry) to the day after completion of intervention (after 4 weeks of behavioral therapy).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2019.
