Eligibility
Key inclusion criteria
1. Evidence of a personally signed and dated ICF indicating that the subject has been
informed of all pertinent aspects of the study.

2. Age >18.

3. ECOG performance status of 0-1.

4. Life expectancy of =3 months.

5. Subjects with pathologically diagnosed advanced relapsed or refractory solid tumors,
either gastric and gastroesophageal junction (GEJ) cancer, or pancreatic cancer, who
are intolerable to SoC, have progressed through all available treatment options, or
for whom there is no efficacious treatment available. Subjects must have pathological
classification (e.g., adenocarcinoma etc.) documented.

6. Positive expression of Claudin 18.2 (>=50% of cells with 2+ or 3+ expression, either
from fresh or archival tissue) is required prior to enrollment and participation in
this study. Positivity for Claudin 18.2 is defined as tumor cells showing partial or
complete membrane staining. The percentage of tumor cells at four different staining
intensities will be estimated: 0 (no staining), 1+ (weak), 2+ (moderate), and 3+
(strong). The sum of all 4 percentages should equal 100%. The H-score is determined
according to the H-Score formula: [1 x Percentage of tumor cells stained at 1+] + [2 x
Percentage of tumor cells stained at 2+] + [3 x Percentage of tumor cells stained at
3+] = H-Score (range 0 or 1-300). Actual figure of Claudin 18.2 expression tested by
IHC should be documented. Subjects must have pathological classification (e.g.,
adenocarcinoma) documented.

7. Has at least one measurable lesion as defined by RECIST v1.1.

8. Has adequate organ and bone marrow function within 7 days prior to administration of
study treatment defined below: with no blood transfusion or hematopoietic growth
factor support within 2 weeks prior to screening): • Absolute neutrophil count (ANC)
=1.5 × 109 /L • Platelet count (PLT) =100 × 109 /L • Hemoglobin (Hb) =90 g/L • TBIL
=1.5 × ULN • ALT and AST =3 × ULN (=5 × ULN for liver metastasis) • Creatinine
clearance =60 mL/min/1.73 m2 based on Cockcroft-Gault equation (Appendix 5) •
Activated partial thromboplastin time (APTT) and prothrombin time (PT) =1.5 × ULN. •
Fridericia-corrected QT interval (QTcF) =450 msec. If ECG demonstrates QTc >450 msec
at screening, an ECG re-examination is allowed, and subjects will be eligible if it
demonstrates QTc = 450 msec. • LVEF =50%.

9. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test
within 3 days before the first dose. WOCBP and male subjects whose partners are WOCBP
must agree to use effective contraception method during the study period and within 5
half-lives of SHR-A1904 + 6 months after the last dose of SHR-A1904. (see Appendix 2
for details).

Key exclusion criteria
1. Plan to receive any other anti-tumor treatments during the treatment period of this
study.

2. Subjects participated in a prior investigational study or received anticancer
treatment, and have not recovered from side effects of such therapy.

3. Underwent major surgical operation within 4 weeks before the first dose of this IP.

4. Received treatments with strong CYP3A4, CYP2D6, P-gp, or BCRP inhibitors or inducers
within < 5 half-lives of the drug before the first dose of the study.

5. Previously received total gastrectomy (only for subjects of the dose-escalation part.

6. Adverse events caused by previous anti-tumor treatments have not recovered to Grade =1
according to NCI-CTCAE 5.0 (except for alopecia; some tolerable chronic Grade 2
toxicities may also be excluded as judged by the investigator after consultation with
the sponsor).

7. Known to be allergic to any component of SHR-A1904 product (antibody conjugated toxin,
antibody), or allergic to humanized monoclonal antibody products.

8. Subjects with known brain metastases, unless the participant is > 1 month from
definitive therapy (surgery or radiotherapy), has no evidence of tumor growth on an
imaging study and is clinically stable with respect to the tumor at the start of study
intervention.

9. Subjects with a second primary cancer, except adequately treated non-melanoma skin
cancer, curatively treated in situ cancer of the cervix, and other solid tumors
curatively treated with no evidence of disease for =3 years prior to the first dose of
the study.

10. Class III-IV cardiac insufficiency as per the New York Heart Association (NYHA)
criteria; arrhythmia requiring long-term drug control; unstable angina or acute
myocardial infarction within 6 months before the first dose of the study.

11. Subjects with a history of clinically significant lung diseases (e.g., interstitial
pneumonia, radiation pneumonia, and pulmonary fibrosis) or who are suspected to have
these diseases by chest imaging at screening period.

12. Serious infections that require use of intravenous antibiotics, antiviral drugs, or
antifungal drugs during the study period.

13. Hepatitis B (HBV, chronic or acute; defined as having a known positive hepatitis B
surface antigen [HbsAg] test at the time of screening) or hepatitis C (HCV) infection
requiring treatment

14. Has a history of immunodeficiency (including positive results of HIV test in
screening, and other acquired and congenital immunodeficiencies) or organ transplant.

15. Presence of accompanying diseases (such as poorly controlled hypertension, serious
diabetes mellitus, thyroid disorder, psychosis, etc.) that may pose serious risks to
the safety of the subject or may affect the subject's ability to complete the study,
or any other situation as judged by the investigator.

Summary
Brief summary
The study (dose escalation/expansion) is being conducted to assess the safety and
tolerability of SHR-A1904 in subjects with advanced solid tumors, and to determine maximum
tolerated dose (MTD) and/or recommended phase II dose (RP2D), to assess preliminary efficacy
of SHR-A1904, pharmacokinetic (PK) profile and immunogenicity of SHR-A1904 in subjects with
advanced solid tumors.
