United States Patent 9,125,939: A Detailed Analysis

Introduction

The United States Patent 9,125,939, titled "Carbostyril derivatives and mood stabilizers for treating mood disorders," is a significant patent in the field of psychiatric pharmacology. This patent, granted on September 8, 2015, covers compounds and methods for treating various mood disorders, including bipolar disorder and major depressive disorder.

Background

Mood disorders, such as bipolar disorder and major depressive disorder, are complex psychiatric conditions that affect millions of people worldwide. The treatment of these disorders often involves a range of pharmacological interventions, including mood stabilizers and antipsychotic medications. Aripiprazole, a compound mentioned in this patent, is a well-known antipsychotic medication with partial agonist activity at the 5-HT1A receptor, which is beneficial in treating types of depression and bipolar disorder[1].

Patent Overview

Inventors and Assignees

The patent was assigned to Otsuka Pharmaceutical Co., Ltd., a Japanese pharmaceutical company known for its innovative treatments in various therapeutic areas, including psychiatry.

Claims

The patent includes multiple claims that define the scope of the invention. Here are some key aspects:

  • Chemical Compounds: The patent claims cover specific carbostyril derivatives, which are chemical compounds with potential therapeutic effects on mood disorders. These compounds are described in detail, including their structural formulas and methods of synthesis[1].
  • Mood Stabilizers: The patent also claims mood stabilizers, including combinations of the carbostyril derivatives with other known mood stabilizers like lithium, valproate, and aripiprazole. These combinations are intended to enhance the therapeutic efficacy in treating mood disorders[1].
  • Methods of Treatment: The claims include methods for treating mood disorders, such as bipolar I disorder, bipolar depression, and major depressive disorder, using the claimed compounds and combinations[1].

Scope of the Patent

Therapeutic Indications

The patent covers a broad range of therapeutic indications, including:

  • Bipolar I Disorder: The treatment of manic and mixed episodes associated with bipolar I disorder.
  • Bipolar Depression: The treatment of depressive episodes in bipolar disorder.
  • Major Depressive Disorder: The adjunctive treatment of major depressive disorder[1][2].

Compound Specificity

The patent specifies the carbostyril derivatives and their use in combination with other drugs. For example, the combination of these derivatives with aripiprazole is highlighted for its potential in treating mood disorders[1].

Patent Landscape

Related Patents

The patent landscape surrounding US 9,125,939 includes several related patents that cover similar therapeutic areas and compounds. For instance:

  • Patent 8,642,600: Covers the acute treatment of manic and mixed episodes associated with bipolar I disorder, among other indications[2].
  • Patent 9,089,567: Relates to the treatment of cognitive impairments and schizophrenia, indicating a broader scope of psychiatric treatments by the same assignee[4].
