Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Primary outcomes

  1. Number of Participants With Serious Adverse Events (SAEs), Treatment-Emergent Adverse Events (AEs), Deaths, AEs Leading to Discontinuation, Extra Pyramidal Syndrome (EPS)-Related AEs

    Participants with Adverse Events (AEs), Deaths, Serious AEs (SAEs), and AEs leading to study discontinuation. AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition. SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a cancer, is a congenital anomaly/birth defect, results in the development of drug dependency or drug abuse, is an important medical event.

    Time frame: From Screening (up to 42 days prior to treatment start) through Week 52 (end of study) for SAEs; from Week 0 (Baseline) through Week 52 (End of Study) for AEs

  2. Mean Change From Baseline in Total Simpson-Angus Scale (SAS) At Week 8, Week 26, and Week 52

    The SAS is a 10-item instrument used to evaluate the presence and severity of parkinsonian symptomatology. It is the most commonly used rating scale for Parkinsonism in clinical trials over the past 25 years. The ten items focus on rigidity rather than bradykinesia, and do not assess subjective rigidity or slowness. Items are rated for severity on a 0-4 scale, with definitions given for each anchor point. The total SAS Score has a possible range from 10 to 50. Negative change scores indicate improvement.

    Time frame: Baseline, Week 8, Week 26, Week 52

  3. Mean Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) At Week 8, Week 26, and Week 52

    The AIMS is an assessment of movement dysfunctions. It is a 12-item instrument assessing abnormal involuntary movements associated with antipsychotic drugs and 'spontaneous' motor disturbance related to the illness itself. Scoring the AIMS consists of rating the severity of movement in 3 main anatomic areas (facial/oral, extremities, and trunk), based on a five-point scale (0=none, 4=severe). The AIMS Total Score has a possible range from 0 to 28. Negative change scores indicate improvement in movement dysfunction.

  11. Mean Change From Baseline by Time Period in Body Weight Z-Score

    The Z-Score indicates how many standard deviations a person is from the population norm values. The body weight z-scores are designed to take into account the amount of weight gain that would be expected due to normal growth in children and adolescents. The body weight z-scores are by age and gender standardized values (corresponding to a normal distribution with mean 0 and a standard deviation of 1) of the actual weight measurements, based on the Growth Charts provided by the Centers for Disease Control (CDC; see Links section of this record). Subjects included in the period evaluation had a baseline and at least 1 measurement within the time period that was assessed. Patients are only counted once in each time period but can appear in multiple time periods. For those with multiple records in 1 time period, only the last record in that period is included in calculations.

These abbreviations are used in the table of ECG measurements: supraventricular (SV), baseline (BL), 1 degree (1°), atrioventricular (A-V), intraventricular (IVT), symmetrical (SYM), corrected QT interval (QTc). QRS complex is a recording of a single heartbeat on ECG corresponding to the depolarization of the right and left ventricles. PR interval is measured from beginning of P wave to beginning of QRS complex. QT interval is a measure of time between start of Q wave and end of T wave in the heart's electrical cycle. ↑ = increase from baseline, ↓ = decrease from baseline, → = "to"

PrimaryMean Change From Baseline by Time Period in Body Weight Z-Score

The Z-Score indicates how many standard deviations a person is from the population norm values. The body weight z-scores are designed to take into account the amount of weight gain that would be expected due to normal growth in children and adolescents. The body weight z-scores are by age and gender standardized values (corresponding to a normal distribution with mean 0 and a standard deviation of 1) of the actual weight measurements, based on the Growth Charts provided by the Centers for Disease Control (CDC; see Links section of this record). Subjects included in the period evaluation had a baseline and at least 1 measurement within the time period that was assessed. Patients are only counted once in each time period but can appear in multiple time periods. For those with multiple records in 1 time period, only the last record in that period is included in calculations.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2006 to primary completion in Jun 2009, 33 months.

Results were first posted in Jan 2010, 7 months after primary completion.

Of 15 phase 3 interventional studies under Autistic Disorder, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 48. This study's 33 months is close to that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 4, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
