    On February 28, Simcere Pharma and Vivoryon Therapeutics of Germany jointly announced that SIM0408, a new drug under development for Alzheimer's disease jointly developed by the two parties in China, has been approved by the Center for Drug Evaluation of the State Drug Administration to enter clinical trials in China

    SIM0408 is a differentiated oral small molecule investigational drug candidate for Alzheimer's disease with the potential to address multiple key AD pathological mechanisms in a unique mode, including Aβ pathology, neuroinflammation and synaptic damage

    SIM0408 blocks glutaminyl cyclase (QPCT) action associated with AD pathology
    The enzyme, which is present in much higher levels in the brains of AD patients than in healthy individuals, catalyzes the formation of N3pE amyloid

    This is a highly neurotoxic variant of the Aβ peptide characteristic of AD patient brains that may act as a seed for Aβ aggregation leading to the formation of highly neurotoxic soluble pE-Aβ oligomers (pE-AβO) and ultimately Nerve plaques, causing cognitive decline in AD patients

    The mechanism of action of SIM0408 is located in the same pathway as some current popular AD therapies, but the mechanism of action is more upstream, aiming to prevent the formation of more neurotoxic N3pE-Aβ and Aβ oligomer (Aβ oligomer) before plaque formation

    Second, the enzymatic activity of glutaminyl cyclase is associated with the pro-inflammatory protein CCL2

    QPCTL, an isoenzyme of QPCT, upregulates CCL2 by converting it to pE-CCL2

    Therefore, blocking QPCTL has the potential to reduce neuroinflammation

    In addition, CCL2 is a promoter of tau pathology, which in turn is associated with synaptic damage

    Aroglutamstat is able to target these pathologies simultaneously and, compared to many other investigational AD drugs (antibodies that must be injected or infused), is available in oral tablets for ease of administration
