Is this trial a fit for you?

Likely a good fit

Adults with a confirmed diagnosis of schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder and neuroleptic-induced TD for at least three months with AIMS dyskinesia total score ≥6 are ideal candidates.

Probably not a fit

Patients with comorbid parkinsonism, only mild TD, or TD not caused by neuroleptic exposure are unlikely to benefit from this specific trial.

What this trial studies

This Phase 2 interventional trial compares the investigational drug NBI-1065890 to placebo in adults who have neuroleptic-induced tardive dyskinesia and a qualifying psychiatric diagnosis. Participants must have had TD for at least three months and meet a minimum severity threshold on the AIMS dyskinesia total score as confirmed by a blinded external video reviewer. Dosing is compared against placebo while blinded certified site raters and external reviewers use AIMS video assessments to measure changes in abnormal movements; safety and tolerability are also monitored. The study is being conducted at Neurocrine Clinical Sites in California and Florida.

Why it matters

Potential benefit: If effective, NBI-1065890 could reduce the severity of involuntary movements and improve daily functioning for people with tardive dyskinesia.

How similar studies have gone: Drugs targeting the same general pathway (VMAT2 inhibitors such as valbenazine and deutetrabenazine) have shown benefit in TD, so this approach builds on established pharmacology though NBI-1065890 itself is investigational.

Key Inclusion Criteria:

* Medically confirmed diagnosis of schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder (MDD) as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) for at least 3 months prior to screening.
* Medically confirmed diagnosis of neuroleptic-induced TD as defined in the DSM-5 for at least 3 months prior to screening.
* Moderate or severe TD (AIMS Item 8, severity of abnormal movement overall) as assessed by a blinded, external AIMS video reviewer using a video recording of the participant's AIMS assessment administered at the clinical site by a blinded, certified site AIMS rater. The AIMS dyskinesia total score (sum of Items 1 to 7) must be ≥6 as assessed by the blinded, external AIMS video reviewer.

Key Exclusion Criteria:

* Comorbid parkinsonism (drug-induced or otherwise) or more than a minimal level of extrapyramidal signs/symptoms, as documented by a score on the Modified Simpson-Angus Scale (mSAS) (excluding Items 8 and 10) \>6 at screening or Day -1 (baseline) or a score \>3 in any one item (excluding Items 8 and 10).
* Barnes Akathisia Rating Scale (BARS) global clinical assessment score ≥2 at screening or Day -1.
* Brief Psychiatric Rating Scale (BPRS) total score ≥50 at screening or Day -1.
* Hospitalized for schizophrenia, schizoaffective disorder, bipolar disorder, or MDD within 6 months of screening.
* Participant has an unstable medical condition or unstable chronic disease.
* Any known history of neuroleptic malignant syndrome (NMS).

Note: Other protocol-defined inclusion and exclusion criteria may apply.
