TYVYT® and PEMAZYRE® were newly approved in the Macaumarket.

TYVYT® and BYVASDA® were included in the NRDLfor the treatment of EGFR-mutated NSCLC.

Solidify oncology leadership; in active preparation for new commercial opportunities in general biomedicine.

Oncology:we strengthened our leadership with a robust product portfolio,including TYVYT® (sintilimabinjection),and expanded out oncology business with a 10th product,a ROS1 inhibitor,set for approval in the second half of 2024.

General biomedicines:Following the approval of the first CVMproduct SINTBILO® (tafolecimabinjection) in 2023,we have successfully submitted three new drug applications (NDA)—two for mazdutide,targeting obesity/overweight population and T2D,and one for IBI311 (IGF-1R) for thyroid eye disease (TED). As a key strategic priority,we are steadily building our commercialization capabilities inthe CVMfield with systematic approaches,aiming to unlock substantial commercial opportunities and drive sustainable growth.

Material innovation delivery supports strategic goals

7 new assets are in NDA review or pivotal registrational clinical trials,and 18 assets are in early-phase clinical studies

Substantial milestones delivered for key late-stage assets

Encouraging progress in the next wave innovation of "IO+ADC"

TYVYT® (sintilimab): submitted anNDAfor its eighth indication,2L endometrialcancer (EMC). New registrationalclinical trials for neoadjuvanttherapy in colon cancer and perioperativetherapy in NSCLChave been initiated. Additionally,we are exploring the potential of combination therapies through multiple collaborations with novel modalities.

IBI310 (CTLA-4)：initiated a Phase3 clinical trial for IBI310 in combination with sintilimabas neoadjuvanttherapy in treating colon cancer.

IBI343 (CLDN18.2 ADC)：Phase 1b positive data readout in GCand a Phase 3 trial is in preparation.

Accelerating new launch momentum in general biomedicine to unlock significant opportunities

Mazdutide (GLP-1R/GCGR) : first NDAfor weight managementin obese or overweight populations and second NDAfor T2D treatment,both under NMPAreview. We plan to develop new indications,including adolescent obesity,metabolic dysfunction-associated steatohepatitis(MASH),obstructive sleep apnea (OSA),and heart failure with preserved ejection fraction (HFpEF).

Teprotumumab (IGF-1R) : the NDAfor TED is under NMPAreview.With a longstanding lack of innovative TED treatments in China,Teprotumumabis set to be a transformative therapy for this significant unmet need once approved.

Picankibart (IL-23p19) : the only IL-23p19 that reportedover 80% subjects achieving ≥90% improvement in Psoriasis and Severity Index (PASI90) in 16 weeks of treatment,along with strong long-term skin clearance maintenance andquarterly dosing interval advantage. We plan to submit an NDAin the second half of 2024.

IBI128 (XOI) :potential best-in-class XOIfor the treatment of hyperuricemiain gout patients. It is currently undergoing overseas Phase 3 clinical trials overseas with our partner LG Chem,and we have completed patient enrollment for a Phase 2 clinical trial in China.

IBI302 (VEGF/C) :Phase 3 study initiatedfor the treatment of nAMD,following stable and robust visual benefit observed with anextended dosing interval and potential macular atrophy inhibition in two Phase 2 studies.
