The Evolving Landscape of Alzheimer’s Treatment

As the fight against Alzheimer’s Disease (AD) continues, researchers are exploring new frontiers in treatment methods. Despite recent breakthroughs involving monoclonal antibodies targeting amyloid plaques, experts agree that these alone might not unravel the full mystery of AD. Enter repetitive transcranial magnetic stimulation (rTMS), a cutting-edge approach that is gaining momentum in the realm of cognitive restoration.

Targeting the Precuneus for Maximum Impact

Recent studies highlight the precuneus (PC) as a prime target for rTMS to combat the cognitive decline associated with Alzheimer’s. This area is pivotal within the brain's Default Mode Network (DMN) and is one of the first regions affected by amyloid plaques, leading to a slow decline in cognitive and sensory functions. Sinaptica’s innovative SinaptiStim System has shown remarkable promise, recently demonstrating both efficacy and safety in a phase 2 trial focused on patients with mild-to-moderate AD.

Success in Clinical Trials: A Breakthrough Approach

The phase 2 trial was a meticulous, double-blind, sham-controlled study that spanned 52 weeks. Participants underwent a two-week intensive treatment regimen, receiving daily rTMS over the PC, followed by weekly maintenance sessions. Notably, the results revealed a substantial slow down in cognitive decline, with significant improvements in the Clinical Dementia Rating-Sum of Boxes, sparking excitement about its potential to influence daily living activities.

Insights from Sinaptica CEO: The Future of Alzheimer’s Treatment

NeurologyLive® spoke with Ken Mariash, CEO of Sinaptica, who elaborated on the transformative potential of their personalized neuromodulation strategy targeting the DMN. This innovative treatment adapts to individual patient needs using a combination of TMS and electroencephalography for precision.

Personalized Therapy: The Key to Success?

In 20-minute weekly sessions, patients relax while receiving painless treatments individualized to their brain's response patterns. Findings from the trial underline the effectiveness of this personalized approach—showing an impressive 87% reduction in deterioration of daily activities over the year.

Outstanding Results: What the Data Reveals

The research findings were compelling. Data from the trial indicated that patients receiving the personalized rTMS experienced a 44% slower progression of Alzheimer’s over 12 months. This was accompanied by positive shifts in secondary evaluation metrics, including the Alzheimer’s Disease Assessment Scale and Mini-Mental State Examination.

Navigating Challenges in Neuromodulation Research

However, challenges persist. Training neurologists to utilize TMS effectively is crucial as many are unfamiliar with these techniques, despite their common use in mental health treatment. Additionally, gaining patient acceptance remains a focus—as the medical community works to inform and educate patients about the advantages of non-invasive therapies.

Safety First: A Promising Record

The phase 2 trial demonstrated not only efficacy but also safety, with minimal side effects reported. The promising results, along with a favorable safety profile, pave the way for upcoming studies, hinting at a hopeful trajectory for future AD therapies.

What Lies Ahead: Phase 3 Trials on the Horizon

Looking forward, Sinaptica plans to begin a pivotal phase 3 trial in 2025, bolstered by previous positive outcomes. With ongoing consultations with the FDA under the Breakthrough Device pathway, they aim to solidify this transformative treatment for Alzheimer’s, potentially reshaping the care landscape for millions.
