    Deciphering LAG-3: unveiling molecular mechanisms and clinical advancements. (PubMed, Biomark Res)
    Currently, with the approval of relatlimab, a LAG-3 blocking antibody, a third player, has been used in the fight against cancer...However, the complex biology of LAG-3 may hinder its full development as a therapeutic alternative. In this review, we provide in-depth insight into the biology of LAG-3 and its current and future development in cancer treatment.

    Phase I Study of Fianlimab, a Human Lymphocyte Activation Gene-3 (LAG-3) Monoclonal Antibody, in Combination With Cemiplimab in Advanced Melanoma. (PubMed, J Clin Oncol)
    The current results show a promising benefit-risk profile of fianlimab/cemiplimab combination for patients with advanced melanoma, including those with previous anti-PD-1 therapy in the adjuvant, but not advanced, setting.

    Incidence and time to onset of immunotherapy-related adrenal insufficiency in the I-SPY2 trial. (ASCO 2024)
    Treatment included weekly paclitaxel (T) plus ICI-based tx x 4 cycles, followed by doxorubicin/cyclophosphamide (AC) every 2-3 weeks x 4. 6 completed investigational arms included ICIs: T+pembro x 4, T+pembro x 8 (+/- AC), T+pembro+SD101 (TLR9 agonist), T+durvalumab+olaparib, T+cemiplimab (cemi), and T+cemi+REGN3767 (anti-LAG-3)... The incidence of AI in EBC is higher than has previously been reported in advanced disease, with higher rates observed in those tx with dual immune modulation. No correlation was observed with age; correlation of AI with response predictive subtype and other clinicopathologic features is ongoing and will be presented. Given the high incidence of AI in EBC, close monitoring in the peri/postoperative setting and education of pts and providers is critical, as risk persists even after completion of tx.
