The patent addresses the need for improved diagnostic and therapeutic approaches for neurodegenerative disorders, emphasizing biomarker identification and targeted treatment modalities. It leverages the discovery of specific molecular markers associated with disease progression—primarily focusing on protein aggregation, neuroinflammation, and neurodegeneration pathways.
Core Inventions
The patent’s core contributions involve:
- Detection methods for specific biomarkers such as misfolded proteins (e.g., beta-amyloid, alpha-synuclein).
- Therapeutic agents or methods designed to modulate these biomarkers or their associated pathways.
- Diagnostic compositions capable of identifying early-stage neurodegeneration through biological samples (e.g., blood, cerebrospinal fluid).
- Use of imaging agents that bind selectively to pathological protein aggregates for non-invasive diagnostics.
Claim Analysis
Claim 1 (Independent Claim):
The broadest claim centers on a method for diagnosing neurodegenerative disease involving detecting a biomarker (such as beta-amyloid or phosphorylated tau) using a labeled compound with high affinity and specificity. It sets the foundation for subsequent claims, covering both the composition of the detection agents and the process for diagnosing by binding to pathological proteins.
Scope of Claim 1:
- Applies to disease diagnosis based on biomarkers linked to neurodegeneration.
- Covers the use of specific labeled compounds (e.g., radiolabeled, fluorescent) that bind the target biomarkers.
- Includes sample collection and detection steps applicable to various biological matrices.
Dependent Claims:
Subsequent claims narrow the scope by specifying:
- Types of biomarkers (e.g., alpha-synuclein, tau).
- Specific labels (e.g., PET imaging agents, antibodies, or nanobodies).
- Sample types (blood serum, cerebrospinal fluid).
- Detection methods (e.g., fluorescence, positron emission tomography).
- Therapeutic modalities involving antibodies, inhibitors, or small molecules targeting the same biomarkers.
Implication of Claims:
The patent claims are designed to cover a comprehensive platform—from composition to method—targeting early diagnosis and potential therapeutic intervention in neurodegenerative conditions linked to these biomarkers.
