Navigating the dementia landscape: Biomarkers and emerging therapies

Review

Author: Akhtar, Juber ; Ansari, Vaseem Ahamad ; Verma, Amita ; Maheshwari, Shubhrat ; Singh, Aditya ; Mahmood, Tarique ; Wasim, Rufaida

The field of dementia research has witnessed significant developments in our understanding of neurodegenerative disorders, with a particular focus on Alzheimer's disease (AD) and Frontotemporal Dementia (FTD). Dementia, a collection of symptoms arising from the degeneration of brain cells, presents a significant healthcare challenge, especially as its prevalence escalates with age. This abstract delves into the complexities of these disorders, the role of biomarkers in their diagnosis and monitoring, as well as emerging neurophysiological insights. In the context of AD, anti-amyloid therapy has gained prominence, aiming to reduce the accumulation of amyloid-beta (Aβ) plaques in the brain, a hallmark of the disease. Notably, Leqembi recently received full FDA approval, marking a significant breakthrough in AD treatment. Additionally, ongoing phase 3 clinical trials are investigating novel therapies, including Masitinib and NE3107, focusing on cognitive and functional improvements in AD patients. In the realm of FTD, research has unveiled distinct neuropathological features, including the involvement of proteins like TDP-43 and progranulin, providing valuable insights into the diagnosis and management of this heterogeneous condition. Biomarkers, including neurofilaments and various tau fragments, have shown promise in enhancing diagnostic accuracy. Neurophysiological techniques, such as transcranial magnetic stimulation (TMS), have contributed to our understanding of AD and FTD. TMS has uncovered unique neurophysiological signatures, highlighting impaired plasticity, hyperexcitability, and altered connectivity in AD, while FTD displays differences in neurotransmitter systems, particularly GABAergic and glutamatergic circuits. Lastly, ongoing clinical trials in anti-amyloid therapy for AD, such as Simufilam, Solanezumab, Gantenerumab, and Remternetug, offer hope for individuals affected by this devastating disease, with the potential to alter the course of cognitive decline. These advancements collectively illuminate the evolving landscape of dementia research and the pursuit of effective treatments for these challenging conditions.

Simufilam Reverses Aberrant Receptor Interactions of Filamin A in Alzheimer's Disease.

Article

Author: Wang, Hoau-Yan ; Jockers, Ralf ; Dam, Julie ; Burns, Lindsay H ; Cecon, Erika ; Pei, Zhe

Simufilam is a novel oral drug candidate in Phase 3 clinical trials for Alzheimer's disease (AD) dementia. This small molecule binds an altered form of filamin A (FLNA) that occurs in AD. This drug action disrupts FLNA's aberrant linkage to the α7 nicotinic acetylcholine receptor (α7nAChR), thereby blocking soluble amyloid beta_1-42 (Aβ₄₂)'s signaling via α7nAChR that hyperphosphorylates tau. Here, we aimed to clarify simufilam's mechanism. We now show that simufilam reduced Aβ₄₂ binding to α7nAChR with a 10-picomolar IC₅₀ using time-resolved fluorescence resonance energy transfer (TR-FRET), a robust technology to detect highly sensitive molecular interactions. We also show that FLNA links to multiple inflammatory receptors in addition to Toll-like receptor 4 (TLR4) in postmortem human AD brains and in AD transgenic mice: TLR2, C-X-C chemokine receptor type 4 (CXCR4), C-C chemokine receptor type 5 (CCR5), and T-cell co-receptor cluster of differentiation 4 (CD4). These aberrant FLNA linkages, which can be induced in a healthy control brain by Aβ₄₂ incubation, were disrupted by simufilam. Simufilam reduced inflammatory cytokine release from Aβ₄₂-stimulated human astrocytes. In the AD transgenic mice, CCR5-G protein coupling was elevated, indicating persistent activation. Oral simufilam reduced both the FLNA-CCR5 linkage and the CCR5-G protein coupling in these mice, while restoring CCR5's responsivity to C-C chemokine ligand 3 (CCL3). By disrupting aberrant FLNA-receptor interactions critical to AD pathogenic pathways, simufilam may promote brain health.

CASE DETAILS: According to the complaint, defendants provided investors with material information concerning Cassava's leading drug candidate, simufilam. Defendants' statements included, among other things, clear confidence in simufilam's ability to treat Alzheimer's Disease. On November 25, 2024, Cassava released topline results for the first of its two ongoing Phase 3 studies on simufilam, the "ReThink-ALZ" study. The results indicated that simufilam failed to meet each of the pre-specified primary, secondary, and exploratory endpoints; in sum, simufilam failed to outperform the placebo. Following this news, the price of Cassava's common stock declined dramatically. From a closing market price of $26.48 per share on November 22, 2024, Cassava's stock price fell to $4.30 per share on November 25, 2024, a decline of about 83.76% in the span of just a single day.
