Alzheimer’s disease Overview

Alzheimer’s disease is a progressive neurodegenerative disorder and the leading cause of dementia, primarily affecting older adults. It is characterized by memory loss, cognitive decline, and behavioral changes that gradually impair daily functioning. The disease is driven by the accumulation of amyloid-beta plaques and tau protein tangles in the brain, resulting in neuronal damage and brain atrophy. Early symptoms include forgetfulness and difficulty with planning or problem-solving, which worsen over time. While current treatments mainly provide symptomatic relief, emerging disease-modifying therapies targeting underlying pathology are reshaping the future of Alzheimer’s care.

Alzheimer’s Disease Market Outlook

Existing Alzheimer’s disease treatments are largely aimed at relieving symptoms by influencing key neurotransmitters, including acetylcholine, serotonin, and noradrenaline, while also modulating glutamate and dopamine pathways.

However, these therapies are often associated with adverse effects, underscoring the importance of personalized treatment strategies that consider patient comorbidities and possible drug–drug interactions.

Recent regulatory approvals of LEQEMBI (lecanemab) from Biogen and Eisai, KISUNLA (donanemab-azbt) from Eli Lilly, and Brexpiprazole (REXULTI) highlight a transition toward more precise, targeted, and patient-centric approaches in Alzheimer’s disease care.

Alzheimer’s Disease Drugs Analysis: Competitive Landscape

Masitinib (AB1010) – AB Science

Masitinib is an orally administered tyrosine kinase inhibitor that targets neuro-immune cells such as mast cells and microglia, which accumulate in the central nervous system and play a role in Alzheimer’s disease pathology. Preclinical research indicates that masitinib preserves synaptic integrity by suppressing mast cell activity, leading to improved spatial learning and recovery of synaptic markers. In clinical development, Phase II studies showed therapeutic benefits in patients with mild to moderate Alzheimer’s disease, while Phase IIb/III trials reported a meaningful reduction in the rate of cognitive decline. The drug is currently being evaluated in confirmatory Phase III trials.

Valiltramiprosate (ALZ-801) – Alzheon, Inc.

ALZ-801 is an orally available small-molecule prodrug developed to prevent the formation of neurotoxic amyloid oligomers in the brain. It is a valine-linked derivative of tramiprosate that is metabolized into homotaurine, improving bioavailability and extending systemic exposure. Both ALZ-801 and tramiprosate are further metabolized into 3-sulfopropanoic acid (3-SPA), an active metabolite that inhibits Aβ42 aggregation. Engineered to enhance gastrointestinal tolerability and pharmacokinetic properties, ALZ-801 demonstrated consistent plasma concentrations in Phase I studies. It is currently undergoing Phase III clinical evaluation as a potential disease-modifying therapy for early Alzheimer’s disease.

Tricaprilin (CER-0001) – Cerecin

Tricaprilin (CER-0001), also referred to as AC-1204, is an oral caprylic triglyceride formulation designed to induce sustained mild ketosis and support mitochondrial energy metabolism. Since Alzheimer’s disease is associated with impaired brain glucose utilization, CER-0001 supplies ketone bodies as an alternative fuel source to enhance neuronal metabolism. Caprylic acid is metabolized into acetoacetic acid and β-hydroxybutyric acid, which are converted into acetyl-CoA for energy generation through the citric acid cycle. Clinical data suggest that CER-0001 may improve cognitive outcomes in patients with mild to moderate Alzheimer’s disease, particularly among those who are APOE4-negative.

Bezisterim (NE3107) – BioVie

NE3107 is an oral, brain-penetrant small molecule with combined anti-inflammatory and insulin-sensitizing properties. It selectively modulates the ERK/NF-κB signaling pathway, leading to reduced TNF production and regulated microglial activity without disrupting essential immune functions. Through this dual mechanism, NE3107 may alleviate central nervous system inflammation and insulin resistance, potentially slowing disease progression in Alzheimer’s patients. Formerly known as HE3286, the compound is also being studied in Parkinson’s disease, multiple myeloma, and prostate cancer. Phase III trials in mild to moderate Alzheimer’s disease have been completed, with data presented at AD/PD 2024 in Lisbon, highlighting its potential to reduce neurocognitive decline.
