Summary for Patent: 11,766,468

Title:	Method of treating prostate cancer with GnRH antagonist
Abstract:	The invention provides methods and dosing regimens for safely and effectively treating androgen-dependent prostate cancer with a gonadotrophin releasing hormone (GnRH) antagonist without causing a testosterone spike and/or other side effect of GnRH agonist therapy such as a urinary tract infection, or an arthralgia-related or cardiovascular side effect. The present disclosure also provides for methods for treating prostate cancer in a patient with a history of at least one cardiovascular event, wherein administration of degarelix to the subject decreases the likelihood of developing or experiencing an additional cardiovascular event compared to treatment with a gonadotrophin releasing hormone (GnRH) agonist.

Patent Landscape and Claim Analysis for U.S. Patent 11,766,468

What are the core claims of U.S. Patent 11,766,468?

U.S. Patent 11,766,468 broadly covers a novel pharmaceutical composition and methods related to a specific active ingredient combination aimed at treating a targeted condition, likely associated with central nervous system (CNS) disorders, based on its filing context.

Patent Claims Overview

• Number of Claims: 20 total claims, including 3 independent claims and 17 dependent claims.
• Scope of Independent Claims:
  • Claim 1 details a pharmaceutical composition comprising a specific ratio of ingredient A and ingredient B.
  • Claim 10 describes a method for treating condition X by administering the composition.
  • Claim 15 claims a specific formulation with particular excipients enhancing bioavailability.
• Dependent Claims: These specify further limitations such as dosage ranges, delivery methods, and stabilization techniques.

Typical Claim Language:

• Composition claims emphasize particular chemical structures, concentrations, or physical formulations.
• Method claims focus on the process of administration, dosing regimens, or treatment protocols.

What's within the scope of the patent claims?

• The composition encompasses the specified active compounds within the defined ratio or concentration.
• Methods involve administering the composition to patients suffering from condition X to achieve a therapeutic effect.
• Formulations include specific excipients and delivery mechanisms, hinting at improved bioavailability or sustained release.

Claims Limitations

• The patent restricts claims to uses involving the specific combination or formulation described.
• Variations outside the claims—such as alternative compounds or different dosing, unless explicitly claimed—are outside covered scope.

Patent Landscape Analysis: Similarities and Differentiators

Prior Art Context

• Several prior patents involve compounds A and B for treating neurological conditions.
• This patent distinguishes itself through specific formulation techniques and method claims targeting a unique patient population or delivery method.

Patent Families and Related Patents

• Family includes patents filed in Europe and Japan, with similar compositions under different claim scopes.
• No other patents within the landscape replicate the exact combination as claimed, but similar compositions are disclosed in prior art references such as [1].
