6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The studies described below were conducted with AUSTEDO tablets;
adverse reactions with AUSTEDO XR extended-release tablets are expected to be similar to AUSTEDO tablets.
Patients with Huntington’s Disease Study 1 [see Clinical Studies ( 14.1 )] was a randomized, 12-week, placebo-controlled study in patients with chorea associated with Huntington’s disease.
A total of 45 patients received AUSTEDO, and 45 patients received placebo.
Patients ranged in age between 23 and 74 years (mean 54 years);
56% were male, and 92% were Caucasian.
The most common adverse reactions occurring in greater than 8% of AUSTEDO-treated patients were somnolence, diarrhea, dry mouth, and fatigue.
Adverse reactions occurring in 4% or more of patients treated with AUSTEDO, and with a greater incidence than in patients on placebo, are summarized in Table
5 WARNINGS AND PRECAUTIONS QT Prolongation: Avoid use in patients with congenital long QT syndrome or with arrhythmias associated with a prolonged QT interval ( 5.3 ) Neuroleptic Malignant Syndrome (NMS): Discontinue if this occurs ( 5.4 ) Akathisia, agitation, restlessness, and parkinsonism: Reduce dose or discontinue if this occurs ( 5.5 , 5.6 ) Sedation/somnolence: May impair the patient’s ability to drive or operate complex machinery ( 5.7 ) 5.1 Depression and Suicidality in Patients with Huntington’s Disease Patients with Huntington’s disease are at increased risk for depression, and suicidal ideation or behaviors (suicidality).
AUSTEDO XR and AUSTEDO may increase the risk for suicidality in patients with Huntington’s disease.
In a 12-week, double-blind, placebo-controlled trial, suicidal ideation was reported by 2% of patients treated with AUSTEDO, compared to no patients on placebo;
no suicide attempts and no completed suicides were reported.
Depression was reported by 4% of patients treated with AUSTEDO.
Like all medications, Austedo can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
