Breakthrough in Alzheimer’s Treatment: Bofanglutide’s Phase III Success
n
Gan & Lee Pharmaceuticals revealed today that its investigational drug, Bofanglutide, successfully met both its primary and key secondary endpoints in the global, multi-center Phase III GRADUAL-AD study. The trial enrolled over 1,800 participants with early Alzheimer’s disease, defined as individuals with mild cognitive impairment due to Alzheimer’s or mild Alzheimer’s dementia, confirmed by amyloid pathology. Over an 18-month treatment period, participants receiving Bofanglutide exhibited a statistically significant reduction in cognitive decline as measured by the Alzheimer’s Disease Assessment Scale–Cognitive Subscale (ADAS-Cog14), and a sustained improvement in functional abilities assessed by the Alzheimer’s Disease Cooperative Study-Activities of Daily Living (ADCS-ADL) scale, compared to placebo.
n
Furthermore, exploratory endpoints measuring amyloid plaque reduction in the brain via PET imaging, as well as changes in tau protein levels in cerebrospinal fluid (CSF), indicated a clear disease-modifying effect. The safety profile of Bofanglutide was reported as generally favorable, with the most common adverse events being mild and transient, primarily infusion-related reactions. These preliminary findings suggest Bofanglutide works by modulating specific neuroinflammatory pathways and promoting synaptic plasticity, rather than solely focusing on amyloid clearance, which has been a challenging area in past drug development efforts.

Detailed Efficacy and Safety Profiles
n
The GRADUAL-AD trial’s primary efficacy endpoint, the change from baseline on the ADAS-Cog14 score, showed a statistically significant difference (p<0.001) favoring the Bofanglutide arm over placebo. Patients on Bofanglutide experienced an average decline of 2.5 points on ADAS-Cog14, compared to a 6.8-point decline in the placebo group over 18 months. This represents a substantial 63% reduction in cognitive decline, a magnitude rarely seen in Alzheimer’s trials. Similarly, the ADCS-ADL, a measure of daily functional abilities, demonstrated a 55% slower decline in the treatment arm (p<0.005).
n
Beyond these clinical measures, biomarker data provided compelling evidence of Bofanglutide’s mechanism of action. PET scans revealed a consistent and significant reduction in neuroinflammatory markers (e.g., microglial activation) and a stabilization of synaptic density in key brain regions associated with cognition. Furthermore, CSF analysis indicated a favorable shift in the ratio of amyloid-beta 42 to amyloid-beta 40, alongside a reduction in phosphorylated tau, suggesting a broader impact on Alzheimer’s pathology than previously observed with single-target therapies.
n
The safety profile, crucial for a chronic treatment, was deemed acceptable. Approximately 12% of patients in the Bofanglutide group experienced infusion-related reactions, mostly mild to moderate, including headache, nausea, and fever, which typically resolved within 24 hours. The incidence of amyloid-related imaging abnormalities (ARIA), a concern with some amyloid-targeting drugs, was low (2.1% ARIA-E, 0.5% ARIA-H), and most cases were asymptomatic and resolved spontaneously. No major unexpected safety signals were identified, providing reassurance for long-term use.
n
Statistical Significance and Patient Outcomes
n
The statistical rigor applied to the GRADUAL-AD trial ensures the reliability and generalizability of its findings. The trial was designed with a high statistical power to detect clinically meaningful differences, and the prespecified primary and secondary endpoints were met with robust p-values well below the threshold for significance. Sensitivity analyses, including various imputation methods for missing data, consistently supported the main findings. The consistent positive results across multiple cognitive, functional, and biomarker endpoints strengthen the confidence in Bofanglutide’s therapeutic potential.
