Hoth Therapeutics (NASDAQ: HOTH) made significant strides in Alzheimer’s disease (AD) with its experimental therapy, HT-ALZ, which showed promising results in preclinical studies. Following the announcement of these positive outcomes, the company experienced a remarkable 135% share value surge after Tuesday’s opening bell. While Hoth primarily focuses on dermatology, specifically atopic dermatitis and inflammatory skin conditions, their foray into AD research demonstrates their commitment to addressing unmet medical needs.

More on the HT-ALZ Study for Altzheimers Disease (AD)
In a recent study at Washington University in St. Louis, HT-ALZ showcased encouraging effects, particularly in improving spatial memory, with the higher dosage proving the most effective. Alzheimer’s disease is a degenerative neurological condition characterized by the accumulation of amyloid β (Aβ) plaques and neurofibrillary tangles of Tau protein in the brain, leading to symptoms such as dementia. Hoth’s initial data demonstrated a significant reduction in Aβ levels in both male and female mice with AD after acute treatment with HT-ALZ, compared to the placebo and baseline Aβ levels.

Driving Forces Behind the Expansion of Alzheimer’s Disease Research
Alzheimer’s disease has been receiving increased attention from preclinical biotech companies for several reasons:
- Growing prevalence: Alzheimer’s disease is a significant and escalating public health issue due to its increasing prevalence worldwide. As populations age, the incidence of Alzheimer’s is expected to rise, creating a greater need for effective treatments and interventions.
- High unmet medical need: There is no cure for Alzheimer’s disease, and the available treatments only provide limited symptomatic relief. This unmet medical need presents an opportunity for biotech companies to develop innovative therapies that can potentially slow down the progression of the disease or target its underlying causes.
- Advancements in understanding: Over the years, significant progress has been made in unraveling the complex mechanisms and underlying pathology of Alzheimer’s disease. This improved understanding of the disease has sparked renewed interest among biotech companies, as it provides a foundation for the development of novel therapeutic approaches.
- Technological advancements: The advancements in various scientific and technical fields, such as genomics, proteomics, and imaging techniques, have facilitated better disease characterization and identification of potential drug targets. These tools and technologies enable biotech companies to conduct more detailed research and develop therapies targeting specific pathways or biomarkers in Alzheimer’s.
- Supportive regulatory environment: Regulatory agencies have recognized the urgent need for effective Alzheimer’s treatments and are willing to support and expedite the development and approval processes. This has encouraged biotech companies to invest in Alzheimer’s research and development.
Centers for Medicare & Medicaid Services (CMS) reimbursement For Alzheimer’s Disease (AD)
On a related note, the Centers for Medicare & Medicaid Services (CMS) has announced plans to broaden coverage for Alzheimer’s drugs once they receive full approval from the Food and Drug Administration (FDA). However, CMS’s proposal requires patients to participate in registries that collect real-world data. The first drug that could be covered under this plan is Eisai’s Leqembi, pending FDA approval. CMS’s decision aims to ensure coverage for Medicare Part B enrollees who meet specific criteria, including participation in registries to gather evidence on drug effectiveness.
While the registry requirement has faced criticism as an unnecessary barrier, CMS officials defend it, citing the importance of real-world evidence in transforming patient care. CMS collaborates with multiple organizations to establish registries, but more details and enrollment information are needed.
The broader CMS reimbursement for Alzheimer’s drugs is expected to benefit Eisai, Biogen, and other companies in the anti-amyloid space. Given that over 5 million Medicare beneficiaries are affected by Alzheimer’s, the market potential is substantial. Analysts project significant revenue for Eisai and Biogen from Leqembi, with estimated annual sales in the United States reaching billions of dollars.
Conclusion
In conclusion, the combination of factors such as the growing prevalence of Alzheimer’s disease, unmet medical needs, advancements in understanding, technological progress, and supportive regulations have contributed to the increased attention and investment in AD research by preclinical biotech companies. Hoth Therapeutics’ remarkable improvement in its HT-ALZ study exemplifies the significance of these advancements and highlights the company’s potential in addressing this challenging disease.
