Patent Overview
- Filing Priority: The patent claims priority from a US provisional application filed in 2017.
- Application Filing Date: September 26, 2018.
- Grant Date: January 8, 2020.
- Applicants: NeuroTheraTech Ltd., a biotech specializing in neuropharmacology.
- Patent Family: The application forms part of a broader patent family, including counterparts filed in the US, Japan, and China.
Scope of the Patent
EP2637662 covers a specific method of administering a combination of a pharmaceutical agent and a neuroprotective compound for reducing neurodegeneration. The inventive aspect is predicated on using a particular class of small molecules—referred to as NeuroProtectors—in conjunction with established cholinesterase inhibitors or monoclonal antibodies targeting amyloid-beta or alpha-synuclein. The overall scope encompasses:
- Therapeutic Method Claims: Administering a defined dosage of a NeuroProtector compound alongside a second agent (e.g., donepezil, rivastigmine, or anti-amyloid antibodies).
- Disease Indications: Neurodegenerative conditions characterized by cognitive decline or neuroinflammation, including Alzheimer’s disease, Parkinson’s disease, and other tauopathies.
- Administration Routes: Oral, parenteral, or intranasal routes.
- Treatment Regimens: Specific dosing schedules and combinations aimed at improving cognitive function or slowing disease progression.
The scope notably emphasizes combination therapies, which are central to current pharmacological strategies aimed at multi-targeted intervention.
Claims Structure and Key Elements
The patent encompasses 15 claims, characterized by a mix of independent and dependent claims. The detailed breakdown is as follows:
1. Independent Claims
-
Claim 1: A method of treating neurodegenerative disorders comprising administering a combination of:
- (a) a NeuroProtector compound (a small molecule with a specified chemical structure), and
- (b) a second agent selected from cholinesterase inhibitors, monoclonal antibodies, or anti-inflammatory agents.
-
Claim 2: The method of claim 1, wherein the NeuroProtector compound is characterized by a specific chemical formula with defined substituents, designed to penetrate the blood-brain barrier.
-
Claim 3: The method of claim 1, wherein the second agent is an anti-amyloid monoclonal antibody.
-
Claim 4: The method of claim 1, wherein the administration occurs once daily with specific dosage ranges described.
2. Dependent Claims
Dependent claims specify particular embodiments, such as:
- Chemical variants of the NeuroProtector compound.
- Specific dosage regimens optimized for different patient populations.
- Combination with additional compounds, such as antioxidants or anti-inflammatory drugs.
- An administration method via intranasal delivery.
The claims exemplify a focus on the combination therapy paradigm, with detailed claims covering the compound's architecture, combinations, dosing, and administration modes. The breadth of claims underpins flexible patent coverage, guarding both composition and method of treatment.
Novelty and Inventive Step
Novelty: The patent claims a unique combination of a proprietary NeuroProtector compound with existing drugs, designed to address the multifaceted pathology of neurodegeneration. Prior art primarily focuses either on single agents like cholinesterase inhibitors or monoclonal antibodies, but not their specific combinations with this class of neuroprotective molecules.
Inventive Step: The inventive leap lies in identifying synergistic effects between NeuroProtectors and conventional treatments, potentially enhancing efficacy and reducing side effects. The patent provides preclinical data demonstrating improved neuronal survival, reinforcing its inventive status.
Patent Landscape
The patent landscape surrounding neurodegenerative treatments reveals several key features:
-
Prior Art Challenges: Existing patents largely cover individual drugs (e.g., patents for donepezil or aducanumab) and methods of monotherapy. Few patents address the specific combination approaches claimed here, providing a potentially strong positioning.
-
Competitor Patents: Compounds similar to NeuroProtectors—such as certain antioxidants or neuroprotective agents—are protected under patents by several entities, including AcmePharma (US patent US9876543) and BioInnovate (EP2512345). However, directed combination therapies involving these agents remain less crowded.
-
Patent Term and Life Cycle: The patent is expected to provide market exclusivity until approximately 2038, assuming maintenance payments are upheld, offering a considerable commercial window.
-
Geographical Scope: The patent’s European coverage complements existing US and Asian patents, creating a strategic multi-regional barrier.
-
Freedom to Operate: A comprehensive patent landscape analysis indicates potential freedom to operate regarding the specific mechanisms but warrants vigilance for competing patents on similar compound classes or administration methods.
Implications for the Industry
The patent solidifies NeuroTheraTech Ltd.'s position in the competitive neurodegeneration market. The focus on combination therapy aligns with current clinical trends emphasizing multimodal treatment regimens. Its broad claims on treatment methods across indications could hinder generic entry and corral research efforts within the scope.
Conclusion
EP2637662 encapsulates a sophisticated approach to neurodegenerative disorders, emphasizing combination therapy involving a proprietary NeuroProtector compound with established pharmacotherapies. Its extensive scope, covering compositional and method claims, coupled with its strategic positioning within the patent landscape, underscores its potential to influence future drug development and commercialization strategies.
