T2000 at 600-1000 mg daily
T2000 at previous most effective, well-tolerated dose (600-1000mg daily)
Essential tremor (ET) is a common form of involuntary shaking not related to Parkinson's disease. The medications that are currently used to treat ET work in a small proportion of patients and provide only partial improvement in symptoms. Use of these current medications is also limited by side-effects in many patients.
T2000 is a medication currently under development for the treatment of essential tremor. Although T2000 is a new medication, it belongs to a class of medications that has been used for many years for the treatment of a variety of medical conditions. In previous studies, T2000 appeared to be effective in controlling symptoms of ET and some patients with severe ET had major improvements in tremor. In some patients T2000 was well tolerated for periods up to 5 months and the minimal side-effects seen were those that would be expected for medications in this class.
The current study will evaluate the safety and efficacy of T2000 in patients with moderate to severe essential tremor. Patients will receive doses of T2000 beginning at 600 mg a day, followed by 800 mg a day and up to 1000 mg a day. The total duration of treatment will be 18 months. Patient's tremor and neurological examination will be monitored throughout the study.
