Breakthrough efficacy of IBI363 monotherapy has been achieved in patients with "immune-cold" melanoma, with notable durable response and prolonged survival benefit (Yahoo Finance) - P1 | N=260 | NCT05460767 | Sponsor: Innovent Biologics (Suzhou) Co. Ltd. | "In patients with at least one post-baseline tumor assessment (n=30), the confirmed objective response rate (cORR) was 23.3%, including 25.0% for mucosal type and 20.0% for acral type. The disease control rate (DCR) reached 76.7%, with 85.0% in mucosal type and 60.0% in acral type. In patients treated with 1 mg/kg Q2W with confirmed responses (n=7), a durable response was observed with a median duration of response (DoR) of 14.0 months and events of 42.9%. In patients treated with 1 mg/kg Q2W (n = 31) had a median progression-free survival (PFS) of 5.7 (2.7, 6.8) months, which was significantly longer than data from previous studies (PFS less than 3 months[1] ). The median follow-up time was 14.7 months, the median overall survival (OS) was 14.8 (9.9, NC) months, and the median OS of patients with mucosal subtype was 19.3 (9.9, NC) months. The overall 12-month OS rate was 61.5%."

2025 ASCO Oral Presentation: Innovent Biologics Announces Updated Data of IBI363 (First-in-class PD-1/IL-2α-bias Bispecific Antibody Fusion Protein) from the Phase 1 PoC Clinical Study in Advanced Non-small Cell Lung Cancer (PRNewswire) - P1a/1b | N=260 | NCT05460767 | Sponsor: Innovent Biologics (Suzhou) Co. Ltd. | "As of the data cutoff date, April 7, 2025, a total of 136 patients with NSCLC had received IBI363 monotherapy (2 μg/kg QW~4mg/kg Q3W)....In the 1/1.5 mg/kg dose group, promising ORR/DCR/PFS/OS were observed. Median OS achieved 15.3 months, suggesting the potential long-term survival benefit of IBI363 as a PD-1/IL-2α-bias bispecific immunotherapy. Compared with the 1/1.5 mg/kg dose group, the 3 mg/kg Q3W dose group observed more prominent confirmed ORR (36.7%), DCR (90.0%), PFS (median PFS 9.3 months) and OS trends (median OS not reached, 12-month OS rate 70.9%)....Among the patients with PD-L1 TPS<1%, IBI363 demonstrated outstanding efficacy signals: in the 1/1.5 mg/kg group (N=10), the confirmed ORR was 30.0% and the DCR was 90.0%, while that of the 3 mg/kg group (N=13) were 46.2% and 92.3%, suggesting the potential advantage of IBI363 in the population with low expression of PD-L1."
