Could a botox-like injection quiet shaky hands?
NCT ID NCT07673107
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study tests an investigational drug called gemibotulinumtoxinA (a type of botulinum toxin) injected into arm muscles to reduce tremor in adults with essential tremor. About 94 participants will receive either the drug or a placebo injection. Researchers will measure changes in tremor severity and daily function over 72 weeks, while monitoring for side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gemibotulinumtoxinA (AGN-151607-DP)
- What this could lead to
- If effective, this treatment could offer a new option to reduce hand tremors, making daily tasks like writing and eating easier for people with essential tremor.
- What could go wrong
- This is an early-phase trial with a small number of participants, so results may not apply to everyone. The treatment involves injections and may cause side effects like muscle weakness or injection-site reactions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Minimum body weight of 50 kg (110 pounds) at Screening. * Diagnosis of essential tremor (ET) in accordance with the modified Tremor Research Investigation Group (TRIG) criteria, as follows: * Bilateral postural tremor with or without kinetic tremor, involving hands and forearms * Tremor of other body parts may or may not be present in addition to upper limb (UL) tremor * Bilateral tremor may or may not be asymmetric * Tremor that is reported by the participant to be persistent, although the amplitude may fluctuate. Exclusion Criteria: * History of any medical condition that may put the participant at increased risk with exposure to purified botulinum toxin type A complex, including diagnosed muscular dystrophy (e.g., Duchenne's muscular dystrophy), myasthenia gravis, Eaton-Lambert syndrome, amyotrophic lateral sclerosis, mitochondrial disease, or any other significant disease that might interfere with neuromuscular junctional disorders. * History of an allergic reaction to or significant sensitivity to AGN-151607-DP or its excipients and/or other botulinum toxins.
