First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a single injection of botulinum toxin (NT 201) can reduce hand tremors in people with essential tremor. 78 participants received either the drug or a placebo, and neither they nor the researchers knew who got what. The main goal was to measure tremor improvement using a wearable sensor and a clinical rating scale.

Active substance

Botulinum toxin (NT 201, also known as incobotulinumtoxinA or Xeomin)

What this could lead to

If it works, this could provide a new treatment option to reduce hand tremors in people with essential tremor.

What could go wrong

This is an early phase 2 trial with only 78 participants. The treatment may not work better than placebo, and botulinum toxin can cause muscle weakness or other side effects.
