Anavex Life Sciences has released new data from its Phase 2b/3 trial for its investigational drug, blarcamesine (Anavex®2-73), targeting Alzheimer’s disease. The study, designed to evaluate the safety and efficacy of blarcamesine, demonstrated encouraging outcomes in reducing cognitive decline and neurodegeneration in patients with early-stage Alzheimer’s disease. The study results offer hope for a new oral Alzheimer’s disease medication.
Significant Reduction in Cognitive Decline and Neurodegeneration
The trial enrolled 508 participants diagnosed with early symptomatic Alzheimer’s disease, specifically those with mild cognitive impairment and mild dementia. Participants were randomized to receive either blarcamesine (338 patients) or a placebo (170 patients) for a 48-week duration. Anavex Life Sciences reports that the study met its co-primary endpoints, showing statistically significant reductions in cognitive decline. The mixed model for repeated measures (MMRM) analysis used for the trial revealed a difference in cognitive decline scores, favoring blarcamesine over placebo, with results from both the ADAS-Cog13 and CDR-SB assessments.
The trial data also indicated a significant reduction in brain atrophy and amyloid-beta plaque levels. Magnetic resonance imaging (MRI) scans revealed a reduction in brain volume loss, which is a key indicator of disease progression. Additionally, the trial showed a significant increase in the plasma Aβ42/40 ratio, underscoring blarcamesine’s effect on amyloid pathology, a hallmark of Alzheimer’s disease.
Oral Delivery and Safety Profile
A notable feature of the blarcamesine treatment is its once-daily oral administration, which offers a convenient and non-invasive option for Alzheimer’s patients. Anavex Life Sciences highlights that the drug’s safety profile was well-tolerated by the majority of trial participants. The most common side effect observed was mild to moderate dizziness, primarily during the titration phase, which affected 35.8% of participants. Importantly, these adverse effects were transient, and the safety profile was deemed manageable.
Implications for Alzheimer’s Treatment
The positive outcomes from the trial demonstrate the potential for blarcamesine as a novel therapeutic approach in Alzheimer’s disease, marking it as one of the few oral medications that has shown efficacy in targeting both clinical symptoms and biomarkers of neurodegeneration. This once daily oral dementia treatment represents a significant advancement in the effort to develop more accessible therapeutic options for the disease.
Blarcamesine’s ability to target neurodegeneration, beyond the typical amyloid-focused treatments, positions it as a promising candidate for patients in the early stages of Alzheimer’s. Dr. Christopher U. Missling, CEO of Anavex Life Sciences, expressed optimism about the drug’s development, emphasizing the company’s commitment to advancing treatments for neurodegenerative diseases. He noted that blarcamesine’s efficacy in improving cognitive outcomes and reducing neurodegenerative markers underscores its potential as a convenient and effective treatment option.
Anavex Life Sciences plans to continue discussions with regulatory authorities, with the aim of advancing blarcamesine towards regulatory approval. The drug has already completed earlier trials, and with these promising Phase 2b/3 results, it could become a key treatment option in addressing the growing need for Alzheimer’s therapies.
As Alzheimer’s disease affects millions globally, the potential approval of blarcamesine as a new oral Alzheimer’s disease medication could significantly impact patient care, offering a convenient and scientifically robust solution for slowing disease progression.
