Experiencing Symptoms of Essential Tremor?

Please note: This trial has finished recruiting and is not accepting new participants.

Research Center: The Royal Melbourne Hospital
Location: 4 East, Neurosciences 300 Grattan Street Royal Melbourne Hospital Parkville VIC 3050
Ethics Committee: This study has been reviewed and approved by The Alfred Hospital Ethics Committee


Essential Tremor (ET) is a nerve disorder characterized by uncontrollable shaking, or “tremors,” in different parts and sides of the body. A tremor is an involuntary, rhythmic, movement of a body part. While current treatments are available, these medications do not provide patients long lasting results, with about 50% of patients return to experiencing symptoms and tremors.

This study is looking to understand if a new investigational medication can provide a long lasting response and well-tolerated option for those with essential tremor. This research study involves a study drug that is not approved by any regulatory agency, including Australia’s Therapeutic Goods Administration, so this research is therefore considered experimental. Information gathered from this study may help others with essential tremor in the future.

This study seeks men and women 18-75 who have been diagnosed with essential tremor for at least 3 years and were diagnosed before the age of 65 Participants are required to attend 7 study visits at the research site over approximately 14-16 weeks. Because the study drug may cause sedation and dizziness, caution must be used in activities requiring mental alertness such as driving a car or operating heavy machinery. This impairment may be made worse by other medications that also cause sedation or reduce alertness.

Please note:

Due to the current situation with COVID-19 outbreaks, the study team would like to point out the following:

  • Patients are asked not to participate in research if they have confirmed/suspected COVID-19. The research staff contact all patients prior to appointments to ensure that they do not have symptoms.

  • Hand sanitisers are available at the research site.
  • The research staff adheres to strict hygienic practices as well as other safety measures to prevent the spread of COVID-19.
  • Any staff suspected to have COVID-19, or has come into contact with someone who has COVID-19, will automatically undergo a voluntary quarantine for 14 days.
  • Interested participants will not be left waiting for a long period of time and will be quickly attended to.
  • Parking is available at the research site.
