AGN Allergan plc

DUBLIN, May 15, 2019 /PRNewswire/ -- Allergan plc (NYSE: AGN), a leading global pharmaceutical company, today announced it will showcase data during the upcoming American Psychiatric Association (APA) Annual Meeting in San Francisco, May 18 – May 22, 2019. Data being presented include research on VRAYLAR^® (cariprazine) that investigates its use for the treatment of depressive episodes associated with bipolar I disorder (bipolar depression) in adult patients.

"We are looking forward to sharing data at APA this year that further support the value of VRAYLAR, which now has 10 positive pivotal trials across bipolar I disorder and schizophrenia," said David Nicholson, Chief Research & Development Officer at Allergan. "We are particularly encouraged by the data related to bipolar depression. The potential to treat the full spectrum of bipolar I symptoms, specifically, manic, mixed and depressive episodes, with a single agent, presents an opportunity to streamline treatment decisions for this complicated disorder."

Cariprazine data for bipolar I disorder and cognition symptoms in schizophrenia will be featured in two posters at APA, which will be presented by two leading psychiatry experts, Stephen M. Stahl and Roger S. McIntyre. The titles of the poster presentations are as follows – all noted in local Pacific Time (PT):

• Cariprazine Efficacy in Patients With Bipolar Depression and Concurrent Manic Symptoms: Post Hoc Analysis of 3 Randomized, Placebo-Controlled Studies (#P8-080). Presented by Stephen M. Stahl (2:00 p.m. – 4:00 p.m. PT, Moscone South, Exhibition Level, Room 3-4).
• Effects of Cariprazine on Attentional Processes in Patients With Schizophrenia: Post Hoc Analysis From a Randomized, Controlled Phase III Study (#P7-043). Presented by Roger S. McIntyre (10:00 a.m. – 12:00 p.m. PT, Moscone South, Exhibition Level, Room 3-4).

Cariprazine was approved by the FDA in September 2015 and is marketed as VRAYLAR in the U.S. for the acute treatment of manic or mixed episodes associated with bipolar I disorder in adults and the treatment of schizophrenia in adults. More than 500,000 prescriptions have been written by more than 20,000 prescribers who have treated more than 100,000 patients with VRAYLAR.

About VRAYLAR^® (cariprazine)

VRAYLAR is an oral, once daily atypical antipsychotic approved for the acute treatment of adult patients with manic or mixed episodes associated with bipolar I disorder, with a recommended dose range of 3 to 6 mg/day, and for the treatment of schizophrenia in adults, with a recommended dose range of 1.5 to 6 mg/day.

While the mechanism of action of VRAYLAR is unknown, the efficacy of VRAYLAR could be mediated through a combination of partial agonist activity at central dopamine D₂ and serotonin 5-HT_1A receptors and antagonist activity at serotonin 5-HT_2A receptors. Pharmacodynamic studies with cariprazine have shown that it acts as a partial agonist with high binding affinity at dopamine D₃, dopamine D₂, and serotonin 5-HT_1A receptors. Cariprazine demonstrated up to ~8-fold greater in vitro affinity for dopamine D₃ vs D₂ receptors. Cariprazine also acts as an antagonist at serotonin 5-HT_2B and 5-HT_2A receptors with high and moderate binding affinity, respectively as well as it binds to the histamine H₁ receptors.

Cariprazine shows lower binding affinity to the serotonin 5-HT_2C and α_1A- adrenergic receptors and has no appreciable affinity for cholinergic muscarinic receptors. The clinical significance of these in vitro data is unknown.

VRAYLAR was discovered and co-developed by Gedeon Richter Plc and is licensed by Allergan, in the U.S. and Canada. For more than a decade both companies have conducted over 20 clinical trials enrolling thousands of patients worldwide to evaluate the efficacy and safety of cariprazine for people living with a broad range of mental health illnesses.

INDICATION AND USAGE
VRAYLAR (cariprazine) is indicated in adults for the treatment of schizophrenia and for the acute treatment of manic or mixed episodes of bipolar I disorder.

IMPORTANT SAFETY INFORMATION

Contraindication: VRAYLAR is contraindicated in patients with known hypersensitivity. Reactions have included rash, pruritus, urticaria, and events suggestive of angioedema.

Cerebrovascular Adverse Reactions, Including Stroke: In clinical trials with antipsychotic drugs, elderly subjects with dementia had a higher incidence of cerebrovascular adverse reactions, including fatalities vs placebo. VRAYLAR is not approved for the treatment of patients with dementia-related psychosis.

Neuroleptic Malignant Syndrome (NMS): NMS, a potentially fatal symptom complex, has been reported with antipsychotic drugs. NMS may cause hyperpyrexia, muscle rigidity, delirium, and autonomic instability. Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.  Manage with immediate discontinuation, intensive symptomatic treatment, and monitoring.

Tardive Dyskinesia (TD): Risk of developing TD (a syndrome of potentially irreversible, involuntary, dyskinetic movements) and the likelihood it will become irreversible may increase with the duration of treatment and the cumulative dose. The syndrome can develop after a relatively brief treatment period, even at low doses, or after treatment discontinuation. If signs and symptoms of TD appear, drug discontinuation should be considered.

Late-Occurring Adverse Reactions: Adverse events may first appear several weeks after initiation of VRAYLAR, probably because plasma levels of cariprazine and its major metabolites accumulate over time. As a result, the incidence of adverse reactions in short-term trials may not reflect the rates after longer term exposures. Monitor for adverse reactions, including extrapyramidal symptoms (EPS) or akathisia, and patient response for several weeks after starting VRAYLAR and after each dosage increase. Consider reducing the dose or discontinuing the drug.

Metabolic Changes: Atypical antipsychotics have caused metabolic changes, such as:

• Hyperglycemia and Diabetes Mellitus: Hyperglycemia, in some cases associated with ketoacidosis, hyperosmolar coma, or death, has been reported in patients treated with atypical antipsychotics. Assess fasting glucose before or soon after initiation of treatment, and monitor periodically during long-term treatment.
• Dyslipidemia: Atypical antipsychotics cause adverse alterations in lipids. Before or soon after starting an antipsychotic, obtain baseline fasting lipid profile and monitor periodically during treatment.
• Weight Gain: Weight gain has been observed with VRAYLAR. Monitor weight at baseline and frequently thereafter.

Leukopenia, Neutropenia, and Agranulocytosis: Leukopenia/neutropenia have been reported with antipsychotics, including VRAYLAR. Agranulocytosis (including fatal cases) has been reported with other antipsychotics. Monitor complete blood count in patients with pre-existing low white blood cell count (WBC)/absolute neutrophil count or history of drug-induced leukopenia/neutropenia. Discontinue VRAYLAR at the first sign of a clinically significant decline in WBC and in severely neutropenic patients.

Orthostatic Hypotension and Syncope: Atypical antipsychotics cause orthostatic hypotension and syncope, with the greatest risk during initial titration and with dose increases. Monitor orthostatic vital signs in patients predisposed to hypotension and in those with cardiovascular/cerebrovascular diseases.

Falls: VRAYLAR may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures, or other injuries. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotics and recurrently for patients on long-term therapy.

Seizures: Use VRAYLAR with caution in patients with history of seizures or with conditions that lower the seizure threshold.

Potential for Cognitive and Motor Impairment: Somnolence was reported with VRAYLAR. Caution patients about performing activities requiring mental alertness (eg, operating hazardous machinery or a motor vehicle).

Body Temperature Dysregulation: Use VRAYLAR with caution in patients who may experience conditions that increase body temperature (eg, strenuous exercise, extreme heat, dehydration, or concomitant anticholinergics).

Dysphagia: Esophageal dysmotility and aspiration have been associated with antipsychotics. Antipsychotic drugs, including VRAYLAR, should be used cautiously in patients at risk for aspiration.

Drug Interactions: Strong CYP3A4 inhibitors increase VRAYLAR concentrations, so VRAYLAR dose reduction is recommended. Concomitant use with CYP3A4 inducers is not recommended.

Adverse Reactions: In clinical trials, the most common adverse reactions (≥5% and at least twice the rate of placebo) are listed below:

• Schizophrenia: The incidences within the recommended dose range (VRAYLAR 1.5 – 3 mg/day and 4.5 – 6 mg/day vs placebo) were: EPS (15%, 19% vs 8%) and akathisia (9%, 13% vs 4%)
• Bipolar mania: The incidences within the recommended dose range (VRAYLAR 3 – 6 mg/day vs placebo) were: EPS (26% vs 12%), akathisia (20% vs 5%), dyspepsia (7% vs 4%), vomiting (10% vs 4%), somnolence (7% vs 4%), and restlessness (7% vs 2%)
