As knowledge of Alzheimer's disease (AD) progression improves, the field has recognized the need to diversify the pipeline, broaden strategies and approaches to therapies, as well as delivery mechanisms. A better understanding of the earliest biological processes of AD/dementia would help inform drug target selection. Currently there are a number of programs exploring these alternate avenues. This meeting will allow experts in the field (academia, industry, government) to provide perspectives and experiences that can help elucidate what the pipeline looks like today and what avenues hold promise in developing new therapies across the stages of AD. The focus here is on Active Immunotherapies and Alternative Therapeutic Modalities. This topic includes active vaccines, antisense oligomers, and cell-based therapy among others, and highlights new clinical developments that utilize these modalities.

Background: Alzheimer's disease (AD) agitation is a distressing neuropsychiatric symptom characterized by excessive motor activity, verbal aggression, or physical aggression. Agitation is one of the causes of caregiver distress, increased morbidity and mortality, and early institutionalization in patients with AD. Current medications used for the management of agitation have modest efficacy and have substantial side effects.

Background: Dysregulated GABA/somatostatin (SST) signaling has been implicated in psychiatric and neurodegenerative disorders. The inhibition of excitatory neurons by SST+ interneurons, particularly through α5-containing GABAA receptors (α5-GABAAR), plays a crucial role in mitigating cognitive functions. Previous research demonstrated that an α5-positive allosteric modulator (α5-PAM) mitigates working memory deficits and reverses neuronal atrophy in aged mice.

Anti-Aβ immunotherapies are controversial, in part because of high rates of serious side effects including edema, microhemorrhages, and siderosis, highlighting the importance of the development of alternative Aβ clearance strategy. Here, we introduce a bioinspired nanoparticle named MG-PE3 crossing the human blood-brain barrier (BBB) and clearing Aβ with no adverse effect.

Multiple loss-of-function variants strongly implicate TREM2 as a key regulator of Alzheimer's disease (AD) risk. Accordingly, TREM2 antibodies are currently in development to evaluate the therapeutic potential of TREM2 agonism in neurodegenerative diseases.

Background: Cognitive dysfunction emerges as a manifestation of reduced estrogen levels following ovariectomy in an individual. However, the conventional use of estrogen replacement therapy could increase the risk of breast cancer and thromboembolism. Icariin is a natural compound that has been reported to be a neuroprotective agent against dementia.
