FDA Approves Expanded Use of Vraylar (cariprazine) in the Treatment of Bipolar Depression

In continuation of my update on Cariprazine
Cariprazine.svg
Allergan plc (NYSE: AGN) and Gedeon Richter Plc.   announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental New Drug Application (sNDA) for Vraylar (cariprazine) for expanded use to treat depressive episodes associated with bipolar I disorder (bipolar depression) in adults. Vraylar is also approved in the U.S. to treat manic or mixed episodes associated with bipolar I disorder in adults. There are nearly 11 million adults in the U.S. living with bipolar disorder, a condition that causes extreme shifts in mood, energy, and activity levels.
"Treating bipolar disorder can be very difficult because people living with the illness experience a range of depressive and manic symptoms, sometimes both at the same time, and this FDA approval gives healthcare providers a new option to treat the full spectrum of bipolar I disorder symptoms, specifically manic, mixed, and depressive episodes, with just one medication," said Dr. Stephen Stahl, Professor of Psychiatry at the University of California San Diego and lead author of the post hoc analysis, Cariprazine Efficacy in Patients with Bipolar Depression and Concurrent Manic Symptoms. "Treating depression, mania and mixed episodes with a single medication is important for people living with, and healthcare providers treating, this complex illness. This approval can streamline a treatment decision while helping to stabilize the disorder."
Seventy percent of people living with bipolar disorder receive at least one misdiagnosis and consult an average of four doctors over approximately 10 years before being accurately diagnosed.3 Many patients take multiple medications to treat the symptoms of this condition.
The FDA approval for the expanded indication of Vraylar is based on three pivotal trials, including RGH-MD-53, RGH-MD-54 and RGH-MD-56, in which cariprazine demonstrated greater improvement than placebo for the change from baseline to week six on the Montgomery Asberg Depression Rating scale (MADRS) total score. In all three studies, the Vraylar 1.5 mg dose demonstrated statistical significance over placebo; additionally, in RGH-MD-54, the Vraylar 3 mg dose demonstrated statistical significance over placebo. Common adverse events reported in the pivotal trials were nausea, akathisia, restlessness, and extrapyramidal symptoms.
"This approval represents an important milestone in our efforts to help patients and prescribing healthcare providers effectively manage bipolar I disorder and demonstrates our ongoing focus on mental health," said David Nicholson, Chief Research & Development Officer at Allergan.  "We are committed to developing therapies for complex mental health disorders, including Vraylar, which is currently in Phase 3 clinical trials for the treatment of major depressive disorder."
"This approval is considered a notable achievement in the development process of cariprazine, our flagship product," said Dr. István Greiner, Research Director of Gedeon Richter Plc. "We are pleased that more and more patient groups suffering from psychiatric disorders will get access to cariprazine as a treatment option."
About Vraylar (cariprazine)
Vraylar is an oral, once daily atypical antipsychotic approved for the acute treatment of adults with manic or mixed episodes associated with bipolar I disorder (3 to 6 mg/day) and for the treatment of depressive episodes associated with bipolar I disorder (bipolar depression) in adults (1.5 or 3 mg/day). Vraylar is also approved for the treatment of schizophrenia in adults (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-HT1A receptors and antagonist activity at serotonin 5-HT2A 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-HT1A 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-HT2B and 5-HT2A receptors with high and moderate binding affinity, respectively as well as it binds to the histamine H1 receptors.
Vraylar shows lower binding affinity to the serotonin 5-HT2C and α1A- 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.

Allergan Receives FDA Approval for Vraylar (cariprazine) in the Maintenance Treatment of Schizophrenia

In continuation of my update on Cariprazine

Cariprazine.svg

Allergan plc (NYSE: AGN)  announced that the U.S. Food and Drug Administration (FDA) has approved the supplemental New Drug Application (sNDA) for Vraylar (cariprazine) for the maintenance treatment of adults with schizophrenia. Vraylar is also approved in the U.S. in adults for the acute treatment of schizophrenia and acute treatment of manic or mixed episodes of bipolar I disorder.

"Schizophrenia is one of the most challenging mental health disorders to manage – particularly due to the complexity of patient symptoms, varying response to treatment and high rates of relapse," said Dr. Herbert Meltzer, Professor of Psychiatry and Behavioral Sciences at Northwestern Feinberg School of Medicine. "The goal of clinicians is to minimize relapses, which can cause significant personal distress, and can often have serious implications for a patient's health. The approval of Vraylar for the maintenance treatment of schizophrenia provides an important therapy for patients and physicians who are in need of long-term treatment options."
Without maintenance treatment, 60 – 70 percent of schizophrenia patients relapse within one year. Once a schizophrenia patient reaches the stable or maintenance phase of treatment, it is important for the physician to develop a long-term treatment management plan to minimize relapse risk, monitor for and reduce severity of side effects, and address residual symptoms where possible.2
The efficacy of Vraylar in the maintenance treatment of schizophrenia was based on an up to 72-week, multinational, double-blind, placebo-controlled, randomized withdrawal study in the prevention of relapse in adult patients with schizophrenia. The study included a 20-week open-label phase where patients with schizophrenia were treated with cariprazine 3, 6 or 9 mg per day. Patients who responded and met the stabilization criteria during the open-label period were then randomized either to continue their Vraylar dose (3, 6 or 9 mg per day) or be switched to placebo for up to 72 weeks or until a relapse occurred. The primary endpoint was time to relapse during the randomized, double blind phase.1 The study demonstrated that Vraylar significantly delayed the time to relapse compared to placebo (P=0.0010). Relapse occurred in nearly twice as many placebo-treated patients (49.5%, n=49/99) as Vraylar-treated (29.7%, n=30/101) patients. The safety results were consistent with the profile observed to-date for Vraylar.
"The differences in how people with schizophrenia respond to treatment underscores the importance of having additional treatment options," said David Nicholson, Chief Research & Development Officer at Allergan. "We are pleased that the FDA has recognized the benefits of Vraylar for maintenance treatment of adults with schizophrenia. This approval demonstrates our continued investment in Vraylar, as well as our commitment to developing treatments that address unmet needs facing people living with mental illness."

Vraylar (cariprazine) capsules now approved by FDA to treat schizophrenia, bipolar disorder in adults


Cariprazine.svg


We know that, Cariprazine (trade name Vraylar, previously known as RGH-188) is an antipsychotic drug developed by Gedeon Richter. It acts as a D2 and D3 receptor partial agonist, with high selectivity towards the D3 receptor.  Positive Phase III study results were published for schizophrenia and mania early 2012, while Phase II studies in bipolar disorder I, and for bipolar depression are in progress.  Action on the dopaminergic systems makes it also potentially useful as an add-on therapy in major depressive disorder  

Rights are currently owned by Gedeon Richter and Actavis. The drug received FDA approval on September 17, 2015.


Now The U.S. Food and Drug Administration today approved Vraylar (cariprazine) capsules to treat schizophrenia and bipolar disorder in adults.

"Schizophrenia and bipolar disorder can be disabling and can greatly interfere with day-to-day activities," said Mitchell Mathis, M.D., director of the Division of Psychiatry Products in the FDA's Center for Drug Evaluation and Research. "It is important to have a variety of treatment options available to patients with mental illnesses so that treatment plans can be tailored to meet a patient's individual needs."

Schizophrenia is a chronic, severe and disabling brain disorder affecting about one percent of Americans. Typically, symptoms are first seen in adults younger than 30 years of age and include hearing voices or seeing things that are not there, believing other people are reading their minds or controlling their thoughts, and being suspicious or withdrawn.

Bipolar disorder, also known as manic-depressive illness, is another brain disorder that causes unusual shifts in mood, energy, activity levels and the ability to carry out day-to-day tasks. The symptoms of bipolar disorder include alternating periods of depression and high, irritable mood, increased activity and restlessness, racing thoughts, talking fast, impulsive behavior and a decreased need for sleep.

The efficacy of Vraylar in treating schizophrenia was demonstrated in 1,754 participants in three six-week clinical trials. In each of the trials, Vraylar was shown to reduce the symptoms of schizophrenia compared to placebo.

The efficacy of Vraylar in treating bipolar disorder was shown in three three-week clinical trials of 1,037 participants. Vraylar was shown to reduce symptoms of bipolar disorder in each of the trials.
