PD-L1 IMMUNE CHECKPOINT BLOCKADE IN EARLY ALZHEIMER'S DISEASE: TOPLINE RESULTS FROM THE PHASE IB IBC-01-01 STUDY (ADPD 2026) - "IBC-01-01 is a First-in-Human Phase Ib study assessing safety, tolerability, and preliminary efficacy of IBC-Ab002, a proprietary anti-PD-L1 monoclonal antibody specifically engineered for neurodegenerative disorders. IBC-01-01 represents a novel and innovative approach being investigated as a potential therapeutic for AD and dementia treatment more broadly by leveraging the physiological role of the immune system in brain repair. The results of this study will provide initial data about the potential of this approach, and will inform the design of the planned Phase 2 study."

Unraveling the Immune Puzzle: Role of Immunomodulation in Alzheimer's Disease. (PubMed, J Neuroimmune Pharmacol) - "Preclinical studies of immunomodulatory agents, including salidroside, festidinol, astragalin, sulforaphane, BM-MSC, simvastatin, Ab-T1, hTREM2, and XENP345, demonstrate promising effects. Additionally, clinical investigations of drugs such as simufilam, AL002, TB006, VGL101, DNL919, XPro1595, astragalus, and IBC-Ab002 underscore the therapeutic potential of targeting immune pathways in AD. This review emphasizes how neuroinflammation, microglial activation, and peripheral immune responses contribute to disease progression. By exploring immunomodulatory mechanisms, the article sheds light on potential therapeutic targets that could help mitigate AD pathology which may pave the way for novel interventions preventing neurodegeneration in AD."

HARNESSING PERIPHERAL IMMUNITY: EARLY INSIGHTS FROM IBC-01-01 PHASE I TRIAL DEVELOPING A NOVEL IMMUNE-BASED THERAPY IN ALZHEIMER'S DISEASE. (ADPD 2024) - "Unlike conventional treatments that directly target brain pathology, this trial assesses the safety, pharmacokinetics, and preliminary efficacy of a new anti-PD-L1 antibody, IBC-Ab002. IBC-01-01 adopts an innovative approach in AD treatment, employing for the first time an immune checkpoint inhibitor for the treatment of dementia. Initial findings suggest a promising pharmacological and safety profile, with evidence of intended peripheral target engagement and immune activation. These insights could mark the beginning of a paradigm shift in AD immunotherapy, supporting the contention of the systemic immune system's role in managing neurodegenerative diseases."

IBC-Ab002 Fc modifications for fast clearance are associated with advantageous safety profile (AAIC 2023) - "We demonstrate that the clearance rate of the antibody inversely-relates to the probability of developing an adverse immune response, and that no delayed long-term irAEs are expected once full clearance of the antibody was achieved. Overall, these findings suggest that shortening the half-life of anti-PD-L1 antibodies in treatments that do not necessitate continuous exposure can considerably increase the safety profile."
