How long does it take for Austedo to work?

Austedo (deutetrabenazine) can start improving symptoms within two weeks, based on phase III clinical trials in patients with Huntington’s disease-associated chorea and tardive dyskinesia.

During the dose titration phase of these trials a continuous improvement in symptoms was observed. During the dose titration phase of these trials the dose of Austedo was optimized over six-to-eight weeks, or the dose of Austedo was titrated up over four weeks until the maximum dose the patient was assigned to receive was achieved.

How Quickly Does Austedo Work for Huntington’s Disease?

Improvements in Total Maximal Chorea (TMC) scores were observed by week 2 of a 12-week trial conducted in 90 patients with Huntington’s disease who received either Austedo or placebo.

• The dose was adjusted over the first 8 weeks until symptoms were well controlled, followed by a 4-week maintenance phase.
• Symptoms improved week-by-week during titration. After stopping treatment at week 13, TMC scores returned to baseline levels.

How Quickly Does Austedo Work for Tardive Dyskinesia?

Improvements in Abnormal Involuntary Movement Scale (AIMS) scores were observed by week 2 of two 12-weeks trials, which enrolled more than 300 patients with tardive dyskinesia who received either Austedo or placebo.

• The dose was adjusted over 4 to 6 weeks until dyskinesia was adequately controlled or the assigned maximum dose was reached.
• Patients continued on a maintenance dose for the remainder of the trial, with ongoing improvements in AIMS scores throughout the 12-week period.
• Significant symptom reductions were observed at 24 mg/day and 36 mg/day, but not at 12 mg/day in one trial.
• Another phase III trial reported significant improvements, with an average maintenance dose of 38 mg/day.
