About this study

Official title: Identification, Assessment, and Treatment of Tardive Dyskinesia With Valbenazine in Adults With Intellectual/Developmental Disabilities and Co-occurring Psychiatric and/or Behavioral Disorders

The goal of this open-label clinical trial is to test the safety and efficacy of valbenazine treatment in patients with Intellectual/Developmental Disability (IDD) who have a diagnosis of Tardive dyskinesia (TD). The main questions this study aims to answer are:

  • Does valbenazine treatment of TD in the previously untreated patient population of adults with IDD produce comparable amelioration of signs of movement disorder as what has historically been reported in adults without IDD?
  • Is valbenazine treatment of TD in persons with IDD as safe as what has historically been reported in adults without IDD?
  • Does valbenazine treatment improve Quality of Life (QOL) in persons with IDD and TD treated with valbenazine?
  • Does valbenazine treatment produce positive change in Activities of Daily Living (ADLs) in persons with IDD and TD?
  • Does valbenazine treatment of TD in persons with IDD reduce caregiver burden?

In this study, 25 participants with IDD and TD will undergo valbenazine treatment for 24 weeks. The participants will be seen for a total of 5 visits: at baseline, and at follow up visits at 3 weeks, 6 weeks, 12 weeks, and 24 weeks.

This study does not include a comparison group. Therefore, researchers will compare the response of the study participants to valbenazine treatment with those from a previous reported work that resulted in the FDA approval of this medication.

Read the detailed description

Tardive dyskinesia (TD) is recognized as a common and often debilitating movement disorder, associated with treatment of a variety of illnesses with dopamine receptor-blocking medications (also commonly known as antipsychotic medications. In addition to the distressing and disfiguring movements of TD, there is now also evidence of a reduced quality of life in patients with TD compared to peers with similar psychiatric disorders without TD.

When originally described, TD had been thought to be primarily associated with use of First-Generation Antipsychotics (FGA's, also known as typical antipsychotics), but there are now good studies to suggest that TD is also frequently a result of exposure to Second Generation Antipsychotics (SGA's) as well. Valbenazine, a selective vesicular monoamine transporter 2 inhibitor, is now available to treat the symptoms of TD, with a favorable efficacy and safety profile. This medication offers, for the first time, a treatment option for patients - as well as their caregivers and families - suffering with TD.

Individuals with intellectual and developmental disabilities (IDD) commonly suffer from co-occurring psychiatric and/or behavioral disorders (informally known as a "dual diagnosis"). Such individuals are commonly prescribed antipsychotic medications to treat these co-occurring disorders. Several authors have noted that antipsychotic medications have frequently been over-prescribed for individuals with IDD, often in the absence of an identified psychotic illness. Some studies have shown that up to 20-30% of adults with IDD are prescribed antipsychotic medications across a variety of residential settings.

Surrounding this frequent use of antipsychotic medications in persons with IDD, it is now well-established that persons and that having intellectual disability is a recognized risk factor for developing TD when treated with antipsychotic medications. Finally, recent research has confirmed the long-suspected belief that persons with IDD are MORE susceptible to movement disorder side effects when treated with antipsychotic medications when compared to persons without IDD.

Based on their increased exposure to antipsychotics, and increased susceptibility to movement disorders including TD, it would seem that persons with IDD who have TD are a group who could benefit most from treatment with a novel agent which can address this movement disorder.

Before TD can be treated, it must be clinically identified and formally diagnosed. Once diagnosed, patients and families must be educated on the availability of treatment options, outcomes when no treatment is undertaken, and the potential benefits (and risks) of treatment itself.

Movement disorders such as TD have been diagnosed on the basis of clinical examination, often using formal assessment tools to identify and quantify the movement abnormalities seen. One such instrument is the Abnormal Involuntary Movement Scale (AIMS). The AIMS has been used for many years as the gold standard for this purpose. In addition, there have been recent attempts to quantify the amount of improvement (change in movement intensity, and reduction in AIMS scores) that are considered clinically significant in rating improvement. Additionally, a number of authors have noted the difficulty in using the AIMS in persons with IDD who cannot cooperate fully in the examination process. For this reason, some have suggested using videotaped AIMS exams as a methodology for more accurately quantifying change. Videotaping of exams pre- and post-treatment for blind rating of improvement has been a methodology utilized in a number of recent studies of valbenazine.

In this study, 25 participants with IDD and TD will undergo valbenazine treatment for 24 weeks. The participants will be seen for a total of 5 visits: at baseline, and at follow up visits at 3 weeks, 6 weeks, 12 weeks, and 24 weeks. Consented participants will have an AIMS administered and videotaped at each visit, initially to identify and quantify TD, and subsequently to measure possible response to valbenazine. Subjects' TD response to valbenazine will also be assessed using the Clinical Global Impression of Change (CGI-C) scale (by investigator) and Caregiver Global Impression Scale (by proxy caregiver). Subjects' quality of life will be assessed with the World Health Organization Quality of Life Scale- For Persons with Disability (WHOQOL-DIS), a proxy-reported instrument designed for individuals with IDD, before and after valbenazine treatment. Participants' behavior will be assessed with the Aberrant Behavior Checklist-Irritability Subscale, before and after valbenazine treatment. Subjects' Activities of Daily Living (ADL's) will be assessed with the Waisman Activities of Daily Living Scale (W-ADL), a proxy-reported instrument designed for individuals with IDD and other disabilities, before and after valbenazine treatment. Caregiver burden will be assessed with the Zarit Burden Inventory, short version, before and after valbenazine treatment.

What is being measured

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

  1. Change in AIMS total scores of items 1-7

    The Abnormal Involuntary Movement Scale (AIMS) has been used for many years as the gold standard for this purpose and the amount of improvement (change in movement intensity, and reduction in AIMS scores) have been assessed clinical significance in rating improvement. A number of authors have noted the difficulty in using the AIMS in persons with IDD who cannot cooperate fully in the examination process. For this reason, some have suggested using videotaped AIMS exams as a methodology for more accurately quantifying change. Videotaping of exams pre- and post-treatment for blind rating of improvement has been a methodology utilized in a number of recent studies of valbenazine. The minimum value of the AIMS total score of items 1-7 is 0 and the maximum value is 49. Higher total AIMS scores mean worse outcomes.

    Measured: Baseline and 24 weeks from start of treatment

Secondary outcomes (6)
  1. Change in AIMS item 8 scores

    Item 8 of the AIMS represents an overall index of severity of abnormal involuntary movements. The minimum value of the AIMS total score of items 1-7 is 0 and the maximum value is 4; Higher total scores mean worse outcomes.

    Measured: Baseline and 24 weeks from start of treatment

  2. CGI-C

    Clinical Global Impression of Change (CGI-C), as the names indicates, denotes the clinician's impression of change between baseline and after the treatment in which -3 will be marked worsening, -2 moderate worsening, -1 mild worsening, 0 no change, +1 will be marked for mild improvement, +2 moderate improvement, and +3 marked improvement.

    Measured: Baseline and 24 weeks from start of treatment

  3. CaGI-C

    Caregiver Global Impression of Change (CaGI-C). This is similar to the CGI-C, except that this is the impression of the participant's caregiver, -3 will be marked worsening, -2 moderate worsening, -1 mild worsening, 0 no change, +1 will be marked for mild improvement, +2 moderate improvement, and +3 marked improvement.

    Measured: Baseline and 24 weeks from start of treatment

  4. Change in ABC-I score

    The Aberrant Behavioral Checklist, Irritability Subscale (ABC-I) is commonly used in clinical trials. It consists of 15 items, which are scored on a 4-point Likert scale of severity, ranging from "not at all a problem" to "the problem is severe in degree."

    Measured: Baseline and 24 weeks from start of treatment

  5. Change in W-ADL score

    The Waisman Activities of Daily Living (W-ADL) Scale for adolescents and adults with developmental disabilities, is a validated scale that consists of 17 items in the final version of the W-ADL pertain to the current or expected performance of the target individual at the time when the survey was given. The target adult's performance of each activity is rated on a 3-point scale (0 = "does not do at all", 1 = "does with help", 2 = "independent"), and item scores are summed to produce an overall score. Therefore, this means that the scores can range from a minimum of 0 to a maximum value of 51. Higher total W-ADL scores mean better outcomes.

    Measured: Baseline and 24 weeks from start of treatment

  6. Change in Zarit Burden Interview (short version) score

    The short version of the Zarit Burden Interview is suitable across diagnostic groups of cognitively impaired older adults, and can be used in cross-sectional, longitudinal, and intervention studies. It consists of 12 items, which are answered by a caregiver and measures the change over time, resulting from the progression of (or therapeutic effect of an intervention on) the care recipient's condition. Each item is scored on a 5-point Likert scale, with higher scores indicating greater burden, i.e., worse outcome.

    Measured: Baseline and 24 weeks from start of treatment
