Lewy Body Dementia Treatment Market

Overview

Dementia with Lewy Bodies (DLB) stands as a progressive neurodegenerative condition characterized by cognitive decline, visual hallucinations, and motor symptoms akin to Parkinson's disease. Ranked as the second most prevalent degenerative dementia after Alzheimer's disease, DLB poses diagnostic challenges due to its symptom overlaps with other disorders, necessitating comprehensive assessments blending clinical, imaging, and biomarker data for enhanced accuracy. Its diagnosis demands clinical acumen and a keen awareness, given its fluctuating cognitive patterns, varied motor presentations, and notable visual hallucinations, all of which contribute to its intricate management landscape. Furthermore, the association of DLB with REM sleep behavior disorder underscores its multifaceted nature and emphasizes the need for specialized care approaches to navigate its complexities effectively.

Lewy Body Dementia Diagnosis and Treatment Algorithm

The diagnosis and treatment algorithm for Dementia with Lewy Bodies (DLB) present multifaceted challenges due to the condition's complex symptomatology and overlap with other neurodegenerative disorders. Diagnosing DLB requires a comprehensive assessment integrating clinical evaluation, neuroimaging, and biomarker analysis, given its fluctuating cognitive symptoms, variable motor manifestations, and prominent visual hallucinations, which often lead to misdiagnosis or delayed diagnosis. Effective treatment entails managing symptoms such as cognitive decline, hallucinations, motor dysfunction, and sleep disturbances, although medications may have limited efficacy and potential side effects, necessitating individualized approaches.

A multidisciplinary team approach, involving neurologists, psychiatrists, geriatricians, neuropsychologists, and other healthcare professionals, is crucial for optimal DLB management. Non-pharmacological interventions, including cognitive stimulation therapy, physical exercise, and caregiver support programs, are also essential for enhancing quality of life. Ongoing research aims to develop disease-modifying treatments, improve diagnostic accuracy, and enhance symptom management strategies to address the unique challenges posed by DLB comprehensively.

Lewy Body Dementia Epidemiology

The Lewy Body Dementia epidemiology section provides insights into the historical and current Dementia with Lewy Bodies (DLB) patient pool and forecasted trends for seven individual major countries. It helps recognize the causes of current and forecasted trends by exploring numerous studies and views of key opinion leaders. This part of the report also provides the diagnosed patient pool, its trends, and assumptions undertaken.

Key Findings

• The Lewy Body Dementia Prevalence across the 7MM in 2022 was significant, with an estimated total of approximately 21 million cases, of which around 52% were diagnosed. Projections suggest a continued increase in cases throughout the forecasted period from 2023 to 2034.
• Among the 7MM countries, the United States emerged with the highest diagnosed prevalent cases of dementia, reaching around 5 million individuals. Notably, only approximately 0.3 million, or 5.9% of these cases, were identified as dementia with Lewy bodies, signifying a significant distribution among various dementia subtypes.
• Japan ranked second after the United States in terms of diagnosed prevalent cases of DLB in 2022, accounting for approximately 0.13 million cases, followed by the UK with around 44 thousand cases of all cases across the 7MM.
• DelveInsight's findings highlighted a gender disparity in DLB prevalence across the 7MM, with more cases identified among males compared to females in 2022. Projections suggest a further increase by 2034, urging deeper exploration into factors such as genetic susceptibility and healthcare-seeking behaviors driving this trend.
• In the segmented age groups of 60–69 years, 70–74 years, 75–79 years, 80–84 years, and 85+ years, the highest number of diagnosed cases of DLB was estimated to be in the 85+ years group. 

Lewy Body Dementia Treatment Market

The Lewy Body Dementia treatment market anticipates growth driven by increased awareness and healthcare infrastructure spending. With the rising prevalence of DLB and advancements in understanding the disorder, targeted therapies are expected to drive market expansion. However, the current treatment landscape primarily focuses on symptomatic management, lacking curative options. Mainstay treatments include Acetylcholinesterase inhibitors, Anti-depressants, Anti-psychotics/Mood stabilizers, and Other therapies, aiming to alleviate symptoms. While Japan has seen Donepezil approval, the US and EU4, and the UK await exclusive treatment opportunities, indicating ongoing shifts in treatment patterns and the quest for improved therapeutic options.

The Dementia with Lewy Bodies treatment market suggests a promising landscape with opportunities for innovation, improved treatment options, and better outcomes for individuals affected by this neurodegenerative disorder. According to DelveInsight, the Dementia with Lewy Bodies (DLB) market in the 7MM is expected to change during the study period 2020–2034 significantly.

Lewy Body Dementia Marketed Drugs 

The current Lewy Body Dementia treatment market landscape primarily focuses on symptomatic management, lacking curative or disease-modifying therapies. In 2014, donepezil (ARICEPT) became the first approved DLB treatment in Japan, followed by an expanded approval for zonisamide (TRERIEF) in 2018, the world's first drug indicated for parkinsonism in DLB. Both drugs have gone generic in the Japanese market. While no EMA and FDA-approved DLB treatments exist, off-label use of Alzheimer's drugs like cholinesterase inhibitors, antipsychotics, and other medications such as memantine and zonisamide are common. Cholinesterase inhibitors like donepezil and rivastigmine are recommended as first-line treatments for DLB, targeting cognitive and psychiatric symptoms.

Lewy Body Dementia Emerging Drugs 

The Lewy Body Dementia drugs market dynamics are expected to change, primarily due to increased healthcare spending worldwide. Lewy Body Dementia Companies such as Cognition Therapeutics, Athira Pharma, Eisai Inc., Eli Lilly and Company, EIP Pharma Inc. and others are actively involved in developing Lewy Body Dementia treatments.

• Neflamapimod: EIP Pharma Inc.

EIP Pharma Inc.’s Neflamapimod is a brain-penetrant, oral small molecule that inhibits the intracellular enzyme p38 MAP kinase alpha (p38α). While p38 alpha protects cells from an acute injury, chronically activated p38 alpha activity within neurons can damage synapses and contribute to alpha-synuclein-associated toxicity. In November 2020, the US FDA granted FTD to neflamapimod to investigate treating DLB. The drug has completed a Phase IIa study showing that neflamapimod improves cognitive function in patients with mild-to-moderate DLB. Additionally, the company has initiated a confirmatory Phase IIb clinical trial for DLB.CT1812: Cognition Therapeutics

Cognition Therapeutics’ CT1812, is an orally administered drug. By acting to inhibit the formation of the deleterious α-synuclein oligomers responsible for DLB and the toxic Aβ oligomers driving Alzheimer's disease, CT1812 has the potential to halt the advancement of both diseases. During the course of a 24-week double-blind treatment phase, patients with dementia with Lewy bodies were being investigated for the safety and efficacy of CT1812. The clinical development is currently in Phase II trial in the US.
