[Multiple System Atrophy](/diseases/multiple-system-atrophy) Relevance

AbbVie's neuroscience portfolio has significant relevance to [Multiple System Atrophy](/diseases/multiple-system-atrophy), an α-synucleinopathy with prominent autonomic dysfunction:

• ABBV-954 (α-synuclein inhibitor): Direct relevance to MSA pathogenesis; oligodendrocyte α-syn pathology is a hallmark of MSA
• Autonomic dysfunction expertise: AbbVie's research on autonomic dysfunction in PD (Duodopa, orthostatic hypotension) directly translates to MSA, where autonomic failure is a core feature
• Gene therapy (ABBV-951): AADC gene therapy may have potential for MSA-P variant with severe dopaminergic deficits
• TREM2 partnerships: Neuroinflammation research relevant to MSA pathology

Autonomic Dysfunction in Parkinson's Disease

AbbVie's Parkinson's disease portfolio addresses several autonomic dysfunction manifestations common in PD:

Duodopa/Duopa (Levodopa-Carbidopa Intestinal Gel)

Duodopa provides significant benefit for autonomic symptoms in advanced PD[@olanow2014]:

• GI Dysfunction: Continuous intestinal delivery bypasses gastric emptying issues, addressing gastroparesis and constipation that affect up to 80% of PD patients
• Improved Medication Timing: Stable plasma levodopa levels reduce fluctuations that can exacerbate autonomic symptoms
• OFF-time Reduction: Reducing OFF episodes can decrease catecholamine surges and associated blood pressure fluctuations

AbbVie's neuroscience programs explore mechanisms relevant to orthostatic hypotension:

• Research into alpha-synuclein propagation and its effects on autonomic nuclei including the [dorsal motor nucleus of the vagus](/cell-types/dorsal-motor-nucleus-vagus) and [locus coeruleus](/cell-types/locus-coeruleus-norepinephrine-neurons-in-neurodegeneration)
• TREM2 partnerships may provide insights into neuroinflammation effects on autonomic regulation

| Program | Target | Autonomic Relevance |
|---------|--------|---------------------|
| ABBV-951 | AADC gene therapy | May improve autonomic response to levodopa |
| Alpha-synuclein inhibitors | Propagation | Protect autonomic neurons |

BRAIN Platform Technology

AbbVie has developed the BRAIN (Blood-brain barrier "Receptor" ABC for Intractable CNS) platform, a proprietary technology for delivering large molecule therapeutics across the blood-brain barrier. This platform represents AbbVie's strategic investment in addressing the long-standing challenge of CNS drug delivery.

Mechanism of Action

The BRAIN platform utilizes the CD98hc (CD98 heavy chain, also known as SLC3A2) transporter, which is expressed on brain endothelial cells and mediates amino acid transport across the BBB:

Key Steps:

CD98hc/LAT1 Biology

The CD98hc (SLC3A2) protein forms the heavy chain of the LAT1 (SLC7A5) heterodimeric amino acid transporter. LAT1 is one of the major amino acid transporters at the BBB and is upregulated in certain conditions:

• High expression: LAT1 is overexpressed on brain endothelial cells compared to peripheral endothelium
• Substrate scope: Transports large neutral amino acids, hormones, and therapeutic compounds
• Upregulation: Increased expression in neuroinflammation and some CNS disorders
• Tumor expression: Also overexpressed in many cancers, enabling targeted drug delivery

Comparison to Other BBB Platforms

| Platform | Company | Mechanism | Cargo | Status |
|----------|---------|-----------|-------|--------|
| BRAIN | AbbVie | CD98hc/LAT1 | Antibodies | Preclinical |
| Brain Shuttle | Roche | TfR | Antibodies, siRNA | Phase 2 |
| Transport Vehicle | Denali | LDLR | Gene therapy | Phase 2/3 |
| J-Brain Cargo | JCR | Insulin receptor | Enzymes | Approved (Japan) |

Preclinical Data

AbbVie has presented preclinical data on the BRAIN platform:

• Enhanced brain exposure: 5-10x improvement in brain:plasma ratios compared to conventional antibodies
• Efficacy models: Demonstrated target engagement in Alzheimer's and Parkinson's disease models
• Safety profile: No significant accumulation in brain endothelial cells; normal transporter kinetics

Clinical Pipeline

The BRAIN platform is being applied to several AbbVie CNS programs:

| Program | Target | Modality | Indication | Stage |
|---------|--------|----------|------------|-------|
| ABBV-916 | Amyloid-beta | Antibody | Alzheimer's | Phase 1 |
| BRAIN-enabled tau | Tau | Antibody | Alzheimer's | Preclinical |
| BRAIN-enabled α-syn | Alpha-synuclein | Antibody | Parkinson's | Discovery |

Strategic Importance

The BRAIN platform positions AbbVie competitively in the BBB delivery space:
