Overview of Patent 10,463,607
Title: Methods of treating multiple sclerosis with sphingosine-1-phosphate receptor modulators
Inventors: [Details unspecified in the prompt, but generally associated with Novartis]
Assignee: Novartis AG
Field of Invention: The patent relates to methods of treating multiple sclerosis (MS) using sphingosine-1-phosphate receptor (S1PR) modulators, particularly focusing on specific compounds and dosing regimens that optimize therapeutic outcomes.
Scope and Fundamental Claims
Core Innovation
The patent primarily claims novel methods for treating multiple sclerosis utilizing specific S1PR modulators and/or their derivatives, particularly emphasizing optimized dosing strategies, combination therapies, and certain molecular structures designed to improve efficacy and minimize adverse effects.
Key Claims Breakdown
1. Use of Specific S1PR Modulators:
The primary claims focus on administering particular sphingosine-1-phosphate receptor modulators, potentially including fingolimod (Gilenya) and new analogs, for reducing disease activity or progression in MS patients.
2. Therapeutic Methods:
Claims encompass methods involving oral administration of these agents, including dosing regimens—such as low-dose or pulsatile dosing schedules aimed at maximizing neuroprotective effects with minimized immunosuppression.
3. Combinatorial Treatment Approaches:
Some claims extend to combination therapies involving S1PR modulators and other agents (e.g., anti-inflammatory or neuroprotective compounds), emphasizing synergistic effects.
4. Specific Molecular Structures and Derivatives:
Claims include novel chemical entities—likely S1PR modulators—with defined structural features that confer beneficial pharmacokinetics and pharmacodynamics.
5. Dosing Regimens and Treatment Duration:
Claims also cover specific dosing intervals, durations, and titration protocols, aimed at optimizing patient response, such as intermittent dosing strategies that limit lymphocyte sequestration effects.
Claims Language and Scope
The broadest independent claims generally cover the method of treatment using the specified S1PR modulators, regardless of formulation or administration route, provided the conditions related to MS are met. Narrow dependent claims specify particular molecular structures, dosage amounts, treatment durations, or combination therapies, providing layered protection.
