Abstract:

AL-108 is the intranasal formulation of NAP (a peptide of eight amino acids, NAPVSIPQ). Phase IIa clinical results have recently shown that AL-108 has a positive impact on memory function in patients with amnestic mild cognitive impairment (aMCI), a precursor to Alzheimer's disease (AD). The clinical development of AL-108 has been based on extensive studies showing pre-clinical efficacy for NAP. NAP has demonstrated potent neuroprotective activity in vitro and in vivo. Its mechanism of action is thought to center on the modulation of microtubule stability in the face of outside damage. Such an effect on structures of such central importance in a broad range of cellular functions is thought to explain NAP's activity in wide ranging models of cellular damage and neurodegeneration. The following article reviews NAP's discovery and pharmacological characterization that has led to clinical development of a novel tangle-directed drug candidate.

More about this publication?

Current Alzheimer Research publishes peer-reviewed frontier review and research articles on all areas of Alzheimer's disease. This multidisciplinary journal will help in understanding the neurobiology, genetics, pathogenesis, and treatment strategies of Alzheimer's disease. The journal publishes objective reviews written by experts and leaders actively engaged in research using cellular, molecular, and animal models. The journal also covers original articles on recent research in fast emerging areas of molecular diagnostics, brain imaging, drug development and discovery, and clinical aspects of Alzheimer's disease. Manuscripts are encouraged that relate to the synergistic mechanism of Alzheimer's disease with other dementia and neurodegenerative disorders. Book reviews, meeting reports and letters-to-the-editor are also published. The journal is essential reading for researchers, educators and physicians with interest in age-related dementia and Alzheimer's disease. Current Alzheimer Research provides a comprehensive 'bird's-eye view' of the current state of Alzheimer's research for neuroscientists, clinicians, health science planners, granting, caregivers and families of this devastating disease.
