​Gedeon Richter Plc ("Richter") today announced the amendment of its existing license agreement with Allergan Plc. ("Allergan") for cariprazine to include major markets in Latin America (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru and Venezuela).

Under the terms of the amended agreement Allergan will be responsible for the registration of the compound in the newly licensed territories. Allergan will also pay tiered net sales related royalties to Richter.

"We are very pleased to further increase the geographic coverage of cariprazine for schizophrenia, bipolar I disorder and bipolar depression, providing an innovative treatment for patients suffering of such a complex condition as the spectrum disease", said Gábor Orbán, Chief Executive Officer of Richter.

 

About cariprazine

Cariprazine is an oral, once daily atypical antipsychotic approved by FDA 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). Cariprazine is also approved by FDA for the treatment of schizophrenia in adults (1.5 to 6 mg/day).

While the mechanism of action of cariprazine is unknown, the efficacy of cariprazine 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.

Cariprazine 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.

Cariprazine was discovered and co-developed by Gedeon Richter Plc and is licensed by Allergan, in the U.S. and in Canada. For more than a decade both companies have conducted over 50 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.

Apart from being available in the US for more than 3 years cariprazine is also approved in the EU in schizophenia indication and has already been marketed in 15 European countries.
