    LAG-3 in (auto)immunity and cancer - Emphasising its role in antigen presenting cells. (PubMed, Autoimmun Rev)
    So far, studies show that both approaches may be safe and effective anti-cancer treatment options. This review summarises the role of LAG-3 in immune response and emphasises the role of this IC molecule and its soluble form on APCs function, while also noting the primary physiological function of LAG-3 in autoimmunity and providing a dual perspective of the pros and cons of this novel anti-cancer therapy.

    TACTI-003 Cohort B: Eftilagimod alpha (Soluble LAG-3) and pembrolizumab in first-line recurrent or metastatic head & neck squamous cell carcinoma with PD-L1 negative (ESMO-IO 2024)
    Table: 152P RECIST 1.1 N=31 iRECIST N=31 Complete response (%) 9.7 9.7 Partial response (%) 25.8 29.0 Stable disease (%) 22.6 25.8 Progressive disease (%) 41.9 35.5 Overall Response Rate (ORR)* (%), [95% CI] 35.5, [19.2-54.6] 38.7, [21.8-57.8] Disease Control Rate (DCR) (%), [95% CI] 58.1, [39.1-75.5] 64.5, [45.4-80.8] *10/11 responses confirmed by RECIST 1.1 and 11/12 by iRECIST.Conclusions E + P leads to high ORR and DCR in a CPS negative pt population, which is typically unresponsive to P alone. Further late-stage clinical investigation is warranted for E+P in this disease setting.
