SAN FRANCISCO and SUZHOU, China, March 30, 2025 /PRNewswire/ — Innovent Biologics, Inc.

Recently, Innovent initiated and dosed the first patient for IBI363 in its first pivotal study to evaluate the efficacy and safety of IBI363 monotherapy versus pembrolizumab (Keytruda®) monotherapy in patients with unresectable, locally advanced or metastatic mucosal or acral melanoma who have not received prior systemic therapy.
