What You Need to Know Before You Apply

What is the purpose of this trial?

This is a phase 3, open-label extension study to assess the long-term safety of KarXT for the treatment of mania or mania with mixed features in Bipolar-I disorder (BP-I) The primary objective of the study is to evaluate the long-term safety and tolerability of KarXT in the treatment of participants with mania or mania with mixed features associated with BP-I.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

How is the drug KarXT different from other treatments for bipolar disorder?

KarXT is unique because it combines two components, xanomeline and trospium, which target different pathways in the brain, potentially offering a novel approach to treating bipolar disorder compared to traditional mood stabilizers like lithium and valproate. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

This trial is for individuals with Bipolar-I Disorder who experience manic or mixed episodes. Participants must have completed a prior study of KarXT to join this extension study, ensuring they are familiar with the treatment and its effects.

Inclusion Criteria

Participants who participated in double-blind placebo-controlled study (CN0120036 or CN0120037) must have completed treatment period of parent study.

De novo participants who did not participate in double-blind placebo-controlled studies must have primary diagnosis of Bipolar-I disorder established by a comprehensive psychiatric evaluation based on DSM-5-TR criteria and confirmed by the Mini International Neuropsychiatric Interview (MINI, v7.0.2), with symptoms of mania or mixed mania.

De novo participants who did not participate in double-blind placebo-controlled studies must have Young Mania Rating Scale (YMRS) score of ≥ 14 at Screening and at baseline.

Exclusion Criteria

Participants who participated in double-blind placebo-controlled study (CN0120036 or CN0120037) and discontinued from any KarXT parent studies.

De novo participants who did not participate in double-blind placebo-controlled studies must not have primary diagnosis of BP-I with rapid cycling (ie, ≥ 4 distinct mood episodes in one year).

De novo participants who did not participate in double-blind placebo-controlled studies with a risk for suicidal behavior at baseline as determined by Investigator's clinical assessment or history of suicidal behavior as assessed on C-SSRS.
