**About NovaBridge**

------

NovaBridge is a global biotechnology platform company committed to accelerating access to innovative medicines. The Company combines deep business development expertise with agile translational clinical development to identify, accelerate, and advance breakthrough assets. By bridging science, strategy, and execution, NovaBridge enables transformative therapies to progress rapidly from discovery toward patients in need.

The Company's differentiated pipeline is led by givastomig, a potential best-in-class, Claudin 18.2 x 4-1BB bispecific antibody, and VIS-101, a potential best-in-class bifunctional biologic, targeting VEGF-A and ANG2.

Givastomig conditionally activates T cells via the 4-1BB signaling pathway in the tumor microenvironment where Claudin 18.2 is expressed. Givastomig is being developed to treat Claudin 18.2-positive gastric cancer and other gastrointestinal malignancies. The product candidate is being evaluated in a global, randomized Phase 2 study, following the recent announcement of positive topline results from a Phase 1b, multi-center, open label study in first line gastric cancer. The Company is also collaborating with its partner, ABL Bio, for the development of ragistomig, a bispecific antibody integrating PD-L1 as a tumor engager and 4-1BB as a conditional T cell activator, in solid tumors. Additionally, NovaBridge owns worldwide rights outside of China to uliledlimab, an anti-CD73 antibody that targets adenosine-driven immunosuppression in cancer.

VIS-101 targets VEGF-A and ANG-2 to provide more potent and durable treatment benefits for patients with wet age-related macular degeneration, diabetic macular edema, and retinal vein occlusion. VIS-101 is currently completing a randomized, dose-ranging Phase 2a study for wet AMD. NovaBridge is the majority shareholder of Visara, Inc., and Visara controls global rights to VIS-101, outside of Greater China and certain countries in Asia.
