Breakthrough Clinical Results
Sanofi announced its acquisition of Vigil Neuroscience, a clinical-stage biotechnology company focused on neurodegenerative diseases. This acquisition adds VG-3927, an oral small molecule TREM2 agonist, to Sanofi's neurology pipeline. VG-3927 is intended to treat Alzheimer's disease by enhancing the neuroprotective function of microglia. The acquisition, valued at approximately $470 million, includes a contingent value right for shareholders based on VG-3927's commercial success. VG-3927 will be evaluated in a Phase 2 clinical study. This acquisition strengthens Sanofi's commitment to developing innovative Alzheimer's disease treatments.

Incidence and Prevalence
Global Incidence and Prevalence of Alzheimer's Disease
Alzheimer's disease is the most common form of dementia, affecting nearly one-half of Americans older than 85 years. It is described as one of the most commonly diagnosed cases of senile dementia in the world.
It is estimated that Alzheimer disease affects 15 million people worldwide and approximately 4 million Americans. The disease is more common in the elder population.
Alzheimer's disease represents a major health problem, considering the current increase in the geriatric population all over the world. It accounts for a significant number of cases of senile dementia.
Economic Burden
Economic Burden of Alzheimer's Disease Treatment
United States
Alzheimer's disease (AD) represents a significant economic burden on the United States healthcare system. According to current estimates, AD cost the United States $214 billion in 2014, with projections indicating this cost will increase dramatically to $1.2 trillion by 2050.
The disease currently affects approximately 5 million people in the United States and ranks as the sixth leading cause of death in the country.
Another estimate suggests that Alzheimer disease afflicts millions of older Americans, with an estimated cost to society approaching $100 million annually.
Global Context
The high global prevalence and the socioeconomic burden associated with the disease pose major challenges for public health in the 21st century. Today many countries have rising aging populations and are facing an increased prevalence of age-related diseases, such as AD, with increasing health-care costs.
Key Unmet Needs and Target Populations for Alzheimer's Disease
Unmet Needs in Treatment
One of the most significant challenges in Alzheimer's disease (AD) is the lack of effective treatments. Research consistently shows that:
- AD is particularly devastating, with no cure, no means of prevention, and no proven way to slow progression
- Despite significant efforts, no therapeutics are available that stop or slow progression of AD
- There are no effective pharmacological treatments for reducing the severity of pathology and restoring cognitive function in affected people
- Hundreds of molecules tested in clinical trials in the last decade to treat AD have failed
Emerging Therapeutic Approaches Needed
Research indicates several promising directions that require further development:
- Prevention strategies rather than treatment of established disease
- Physical activity interventions to mitigate AD-related symptoms, "especially when deployed earlier in the disease process"
-
Treatments targeting amyloid-β (Aβ) peptides, including:
-
β-secretase and γ-secretase enzyme inhibitors
-
Passive and active immunotherapies
-
Liposome-based therapies that withdraw Aβ peptides from the brain
- Treatments targeting toxic oligomeric species of Aβ and tau
- Interventions addressing glucose hypometabolism in the brain
- Gene-targeted drugs based on GWAS and eQTL studies
- Better antidepressants for patients with comorbid AD and depression
Target Populations
Recent research has identified several populations requiring targeted intervention:
- Patients with rapid cognitive decline (RCD), characterized by loss of ≥3 points/year in MMSE scores
-
Populations at high risk for RCD including:
-
Females (OR, 1.48 [95% CI, 1.03-2.15])
-
Those with parental history of dementia (OR, 2.32 [95% CI, 1.24-4.21])
-
Patients with psychotic symptoms (OR, 2.06 [95% CI, 1.22-3.48])
-
Malnourished patients (OR, 1.61 [95% CI, 1.06-2.63])
-
Patients with MMSE score < 20
- Patients with mild cognitive impairment (MCI) showing glucose hypometabolism
- Type 2 diabetes mellitus (T2DM) patients, as T2DM is a strong risk factor for AD
- Patients with comorbid major depressive disorder (MDD)
- Aging populations worldwide
These findings highlight the critical need for continued research into both preventative strategies and effective treatments for Alzheimer's disease, with particular attention to high-risk populations and those with specific comorbidities or risk factors.
