A phase II trial of tobemstomig (tobe) + platinum-based chemotherapy (chemo) vs pembrolizumab (pembro) + chemo in patients (pts) with untreated locally advanced or metastatic non-small cell lung cancer (NSCLC) (ELCC 2025) - P2 | "BO44178 (NCT05775289) is a randomised, double-blind, phase II study evaluating tobe + chemo vs pembro + chemo in pts with NSCLC who are ineligible for surgery or definitive chemoradiotherapy. Eligible pts with previously untreated, locally advanced unresectable or metastatic NSCLC were randomised 1:1 to receive either induction tobe + chemo (carboplatin + paclitaxel/pemetrexed) or pembro + chemo for four 21-day cycles, followed by maintenance tobe or pembro with/without pemetrexed every 3 weeks until disease progression, toxicity or loss of clinical benefit. At this interim analysis, no ORR or PFS benefit was observed in pts with untreated locally advanced or metastatic NSCLC receiving tobe + chemo over pembro + chemo. OS data remain immature."

LAG-3 antagonists for cancer treatment: an updated patent review (2020-2025). (PubMed, Expert Opin Ther Pat) - "The trend shows that monospecific antibodies against LAG-3 continue to be the main antagonists, followed by multispecific t, treatment methods using known LAG-3 antagonists, LAG-3 binding peptides, and LAG-3 binding small molecules. The monospecific antibodies encelimab, miptenalimab, and the bispecific antibodies tobemstomig, IBI323, ABL501, fanastomig, and FS118 are added, during this period, to the potential drugs targeting LAG-3."

Neoadjuvant PD-1 and LAG-3-targeting bispecific antibody and other immune checkpoint inhibitor combinations in resectable melanoma: the randomized phase 1b/2 Morpheus-Melanoma trial. (PubMed, Nat Med) - P1/2 | "The NADINA trial evaluating neoadjuvant nivolumab plus ipilimumab and the SWOG-1801 trial evaluating neoadjuvant pembrolizumab have demonstrated superior clinical outcomes with neoadjuvant versus adjuvant checkpoint inhibition...Tobemstomig plus tiragolumab and atezolizumab plus tiragolumab showed a lower pRR versus nivolumab plus ipilimumab (60.0% (12/20) and 45.0% (9/20) versus 77.3% (17/22), respectively)...In conclusion, in the Morpheus-Melanoma study, tobemstomig demonstrated a similar pathological response and improved safety profile versus nivolumab plus ipilimumab in patients with resectable stage III melanoma.
