Neurocrine Biosciences initiates Part II NBI-1065890 research for TD
Neurocrine Biosciences has initiated a Part II scientific trial of NBI-1065890, a selective vesicular monoamine transporter 2 (VMAT2) inhibitor, in adults with tardive dyskinesia (TD).
TD is characterised by involuntary, repetitive actions that have an effect on the trunk, face, or different physique components.

The double-blind, placebo-controlled and randomized section II research goals to evaluate the efficacy, tolerability and security of this investigational agent in TD, a motion dysfunction typically related to long-term use of antipsychotic medicines.
Almost 100 adults with TD are enrolled. The primary efficacy endpoint is the change from baseline in Irregular Involuntary Motion Scale (AIMS) complete dyskinesia rating at week eight.
Neurocrine beforehand developed valbenazine, which acquired U.S. Meals and Drug Administration (FDA) approval in 2017 as the primary remedy for TD. Valbenazine was additionally authorized in 2023 for chorea related to Huntington’s illness.
NBI-1065890 was developed and found internally at Neurocrine Biosciences. It’s administered orally and is at present in scientific improvement for the therapy of TD.
VMAT2 inhibition might present therapeutic advantages in TD and different hyperkinetic motion or central nervous system problems through which dopaminergic signaling is disrupted.
Sanjay Keswani, Chief Medical Officer of Neurocrine Biosciences, mentioned: “NBI-‘890 is an internally found molecule with distinct bodily and chemical properties that would profit a broader vary of sufferers with tardive dyskinesia.
“Advancing this program to a Part II scientific trial is vital to our technique to outline the way forward for VMAT2 biology and ship lasting affect for sufferers.”
In December 2025, Neurocrine reported that its Part III trial evaluating the selective VMAT2 inhibitor valbenazine in pediatric and grownup sufferers with dyskinetic cerebral palsy didn’t meet endpoints.
