Cobenfy Approved for Adult Patients with Schizophrenia

Data from the EMERGENT trials showed statistically significant reductions in schizophrenia symptom severity compared with placebo.

The Food and Drug Administration (FDA) has approved Cobenfy® (xanomeline and trospium chloride) for the treatment of adults with schizophrenia.

Cobenfy® is a first-in-class, twice-daily, oral medication that contains xanomeline, a selective M1 and M4 muscarinic receptor agonist, and trospium chloride, a muscarinic receptor antagonist that works primarily in the tissues peripherally. 

Approval was based on data from the phase 3 placebo-controlled EMERGENT-2 (ClinicalTrials.gov Identifier: NCT04659161) and EMERGENT-3 trials (ClinicalTrials.gov Identifier: NCT04738123) which had identical designs. 

Study participants (N=470) were randomly assigned to receive xanomeline and trospium chloride 50mg/20mg twice daily for 2 days, followed by 100 mg/20mg twice daily for days 3 to 7 days, and then 125 mg/30mg twice daily or placebo for 5 weeks.

The primary endpoint was met by the treatment groups in both trials showing statistically significant reductions from baseline to week 5 in the Positive and Negative Syndrome Scale (PANSS) total score compared with placebo:

  • In the EMERGENT-2 trial there was a 9.6 point reduction (-21.2 xanomeline and trospium chloride vs -11.6 placebo; P <.0001); and
  • In the EMERGENT-3 trial there was an 8.4 point reduction (-20.6 xanomeline and trospium chloride vs -12.2 placebo; P <.0001).

In the EMERGENT-2 trial, the secondary endpoint, change from baseline Clinical Global Impression-Severity (CGI-S) score at week 5, also significantly improved in the xanomeline and trospium chloride group compared with placebo (-1.2 xanomeline and trospium chloride vs -0.7 placebo; P <.0001)

The most common adverse reactions (at least 5% and twice placebo) were nausea, dyspepsia, constipation, vomiting, hypertension, abdominal pain, diarrhea, tachycardia, dizziness, and gastroesophageal reflux disease.

Gordon Lavigne, chief executive officer of the Schizophrenia & Psychosis Action Alliance, said, “People living with schizophrenia want and deserve more. Today’s approval provides a new option as people with schizophrenia move forward with proper support to rebuild their lives.”

Cobenfy® is supplied in 50 mg/20mg, 100 mg/20mg, and 125 mg/30mg capsule strengths of xanomeline and trospium chloride.
