June 2025

Advancing givastomig, a novel bispecific, CLDN18.2 x 4-1BB

Clinical data to date has shown anti-tumor activity with limited toxicities

Clinical activity demonstrated across various CLDN18.2 expression levels, with higher binding affinity than other modalities

5-year survival rate of ~7%1

Metastatic gastric cancer impacts over 250k patients globally2

$12Bn addressable market2 in mGC with potential to expand into other tumor types

Phase 1b escalation study of givastomig in combination with nivolumab plus chemotherapy fully

enrolled (n=17); topline data to be presented in oral presentation at ESMO GI 2025

Phase 1b expansion study enrolling ahead of schedule (n=40); topline data expected in 1H 2026

$168.6M of cash as of March 31, 20253; provides runway into 2027, through expected clinical readouts for givastomig

Capital efficient operating model with U.S.-based management team and clinical operations

The American Cancer Society; based on people diagnosed with cancers of the stomach between 2014 and 2020

Markets include U.S., 5 E.U., and Japan in 2025 based on Data Monitor Biomed Tracker; sales estimates based on 2030 data 3

Includes cash and cash equivalents, and short-term investments

Notes: ESMO GI = European Society of Medical Oncology Gastrointestinal Cancers Congress 2025; mGC = metastatic gastric cancer

Notes: mNSCLC = metastatic non-small cell lung cancer; PD-(L)1 refers to inhibitors of PD-L1 or PD-1; Ab = antibody; mAb = monoclonal antibody; GC = gastric cancers; GEJ = gastroesophageal junction; EAC = esophageal adenocarcinoma cancer; 1L = first line; PFS = progression free survival;

5th most common cancer with 250k patients globally and

4th leading cause of cancer mortality worldwide1

Over 60% of patients are diagnosed at an advanced or

metastatic stage2, where prognosis is poor
