Ordinary share par value US$0.0001 per share Par value of NovaBridge Biosciences ordinary shares entitled to vote
Annual general meeting regulatory
"NOTICE IS HEREBY GIVEN that an annual general meeting of shareholders"
American depositary shares financial
"Holders of the Company’s American depositary shares as of the close"
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
bispecific antibody medical
"givastomig, a potential first-in-class Claudin 18.2 × 4-1BB bispecific antibody"
A bispecific antibody is a specially designed protein that can attach to two different targets at the same time. Think of it as a custom-made connector that brings two things together—such as a disease cell and an immune system component—helping the body fight illnesses more effectively. For investors, understanding bispecific antibodies is important because they represent innovative therapies that could lead to new treatments and potentially lucrative market opportunities.
Accelerated Approval Pathway regulatory
"eligibility for or achievement of Accelerated Approval Pathway"
The accelerated approval pathway is a process that allows new medicines to be approved more quickly based on early evidence that they may be effective, rather than waiting for full proof. This can help patients access promising treatments faster, but it also means ongoing studies are needed to confirm the benefits. For investors, it highlights potential faster market entry and earlier revenue opportunities, along with some uncertainty about long-term outcomes.
deposit agreement financial
"Depositary: Citibank, N.A. Deposit Agreement, dated as of January 22, 2020"
A deposit agreement is a written contract between a customer and a financial institution that outlines the terms for opening and maintaining a deposit account, such as a savings or checking account. It explains important details like how funds can be accessed, any fees involved, and the institution’s responsibilities. For investors, understanding this agreement is important because it clarifies their rights and the rules governing their deposited funds.

About NovaBridge Biosciences

 

NovaBridge is a clinical-stage biopharmaceutical company advancing innovative medicines for areas of significant unmet need. The Company combines deep business development expertise with agile translational clinical development to identify, accelerate, and advance breakthrough assets, enabling transformative therapies to progress rapidly from discovery toward patients in need.

 

The Company’s differentiated pipeline is led by givastomig, a potential first-in-class Claudin 18.2-Targeted Immuno Amplifier (CTIA) — a Claudin 18.2 × 4-1BB bispecific antibody — and VIS-101, a purpose-designed, potential best-in-class dual VEGF-A × ANG-2 inhibitor.

 

Givastomig conditionally activates T cells via the 4-1BB signaling pathway in the tumor microenvironment where Claudin 18.2 is expressed, and is being developed to treat Claudin 18.2-positive gastric cancer and other gastrointestinal malignancies. It is being evaluated in a global, randomized Phase 2 study, following

 


positive topline results from a Phase 1b, multicenter, open-label study in first-line gastric cancer. NovaBridge is also collaborating with its partner, ABL Bio, on ragistomig, a bispecific antibody combining PD-L1 as a tumor engager with 4-1BB as a conditional T-cell activator, in solid tumors. In addition, NovaBridge holds worldwide rights outside of China to uliledlimab, an anti-CD73 antibody targeting adenosine-driven immunosuppression in cancer.

 

VIS-101 targets VEGF-A and ANG-2 to provide more rapid, robust, and durable treatment responses for patients with retinal vascular diseases, including wet age-related macular degeneration, diabetic macular edema, and retinal vein occlusion. It has completed a randomized, dose-ranging Phase 2a study in wet AMD and expects to initiate a dose-determining Phase 2b study in the second half of 2026. NovaBridge is the majority shareholder of Visara, Inc., which controls global rights to VIS-101 outside of Greater China and certain countries in Asia.

Upon the timely receipt from a Holder of ADSs as of the ADS Record Date of voting instructions in the manner specified by the Depositary, the Depositary shall endeavor, insofar as practicable and permitted under applicable law, the provisions of the Deposit Agreement, the Articles of Association of the Company and the provisions of the Deposited Securities, to vote, or cause the Custodian to vote, the Deposited Securities (in person or by proxy) represented by such Holder’s ADSs as follows: (a) in the event voting takes place at a shareholders’ meeting by a show of hands, the Depositary will instruct the Custodian to vote all Deposited Securities in accordance with the voting instructions timely received from a majority of Holders of ADSs who provided voting instructions, and (b) in the event voting takes place at a shareholders’ meeting by poll, the Depositary will instruct the Custodian to vote the Deposited Securities in accordance with the voting instructions timely received from the Holders of ADSs. If voting is by poll and the Depositary does not receive voting instructions from a Holder as of the ADS Record Date on or before the date established by the Depositary for such purposes, such Holder shall be deemed, and the Depositary shall (unless otherwise specified in the Notice of Meeting) deem such Holder, to have instructed the Depositary to give a discretionary proxy to a person designated by the Company to vote the Deposited Securities; provided, however, that no such discretionary proxy shall be given by the Depositary with respect to any matter to be voted upon as to which the Company informs the Depositary that (a) the Company does not wish such proxy to be given, (b) substantial opposition exists, or (c) the rights of holders of Deposited Securities may be adversely affected.

Deposited Securities represented by ADSs for which no timely voting instructions are received by the Depositary from the Holder shall not be voted (except (a) in the case voting is by show of hands, in which case the Depositary will instruct the Custodian to vote all Deposited Securities in accordance with the voting instructions received from a majority of Holders of ADSs who provided timely voting instructions, and (b) as otherwise contemplated in the Deposit Agreement). Neither the Depositary nor the Custodian shall under any circumstances exercise any discretion as to voting and neither the Depositary nor the Custodian shall vote, attempt to exercise the right to vote, or in any way make use of, for purposes of establishing a quorum or otherwise, the Deposited Securities represented by ADSs, except pursuant to and in accordance with the voting instructions timely received from Holders or as otherwise contemplated in the Deposit Agreement. If the Depositary timely receives voting instructions from a Holder which fail to specify the manner in which the Depositary is to vote the Deposited Securities represented by such Holder’s ADSs, the Depositary will deem such Holder (unless otherwise specified in the Notice of Meeting) to have instructed the Depositary to vote in favor of the items set forth in such voting instructions.

Please indicate on the reverse side hereof how the Deposited Securities are to be voted.

The Voting Instructions must be marked, signed and returned on time in order to be counted.

By signing on the reverse side hereof, the undersigned represents to the Depositary and the Company that the undersigned is duly authorized to give the voting instructions contained therein.
