Summary:
The goal of this study is to evaluate the safety, tolerability, pharmacokinetics (PK),
immunogenicity, and anti-tumor activities of cadonilimab in combination with Ivonescimab
plus chemotherapy as first-line therapy in adult subjects with HER2 negative、advanced or
metastatic gastric (G) or gastroesophageal junction (GEJ) cancer.
Detailed description:
The study consists of a dose escalation and expansion phase to determine the recommended
Phase 2 dose (RP2D) for AK104 in combination with AK112 and SOX/XELOX, and a dose
confirmation phase which will further characterize the treatment of AK104 in combination
at the RP2D.
Criteria for eligibility:
Criteria:
Inclusion Criteria:
1. Males or females aged ≥ 18 to ≤ 75 years at the time of signing informed consent.
2. Imaging examination confirmed unresectable locally advanced or metastatic gastric
cancer (GC) or gastroesophageal binding cancer (GEJC), and histopathologically
confirmed adenocarcinoma, with at least one measurable tumor lesion (spiral CT or MR
scan ≥10mm, gonorrhea The short diameter of sling is ≥15mm, which meets the RECIST
1.1 standard); the lesion that has received radiotherapy is not selected as the
target lesion, unless the radiotherapy lesion is the only measurable lesion and is
clearly advanced according to imaging judgment, it can be considered as the target
lesion;
3. Subjects have not received prior systemic therapy for locally advanced or metastatic
gastric adenocarcinoma or adenocarcinoma of the gastroesophageal junction. For
subjects who have received prior neoadjuvant/adjuvant chemotherapy or
chemoradiotherapy for curative intent, the time between disease progression and last
treatment should be at least 6 months；
4. HER2 is negative. HER2 negative is defined as: IHC 0/1+, or IHC 2+ and FISH/ISH
negative (HER2: CEP17 ratio <2). FISH can be replaced by locally available and
accepted ISH methods (such as DISH);
5. The study allowed the inclusion of Subjects with gastric cancer with peritoneal
metastasis (imaging results or ascites/abdominal lavage cytology test positive);
6. Expected survival period > 3 months;
7. ECOG score: 0-1;
8. All acute toxic reactions caused by previous anti-tumor treatment or surgery are
relieved to level 0-1 (according to NCI CTCAE version 5.0) or to the level specified
in the group/exclusion standard. Except for other toxicicies that researchers such
as hair loss, fatigue and hearing damage believe do not pose a safety risk to the
subjects;
9. Have good organ function (subsists are not allowed to receive blood transfusion or
growth factor support treatment within 7 days before the first administration):
1) Absolute count of neutrophils ≥1.5×109/L; platelets ≥100×109/L; hemoglobulin ≥90g/L
or 5.6mmol/L; 2) Total bilirubin ≤ 1.5 times the upper limit of normal value (ULN);
ALT and AST ≤2.5×ULN, for liver metastasis subjects, ALT and AST ≤5×ULN; albumin
≥3.0g/dL (30g/L); 3) serum creatinine ≤1.5 ×ULN or calculated serum creatinine
clearance ≥50mL/min (Cockcroft-Gault formula calculation).
4) Normal urine routine, or urine protein <2+; if urine protein ≥2+, the 24-hour urine
protein quantity must be ≤1g; 5) Normal coagulation function, international
standardization ratio (INR) ≤ 1.5×ULN, prothrombin time (PT) and activation partial
thrombin time (APTT) ≤ 1.5×ULN; 10. Women of childbearing age must have a negative
pregnancy test (βHCG) before starting treatment. Women of childbearing age and men
(who have sex with women of childbearing age) must agree to use effective
contraceptives continuously during treatment and 6 months after the last therapeutic
dose; 11. Subjects signed the informed consent, and able to follow the planned
visit, research treatment, laboratory examination and other experimental procedures.
Exclusion Criteria:
1. known as squamous carcinoma, undifferentiated cancer or other tissue types of
gastric cancer, or adenocarcinoma mixed with other tissue types of gastric cancer;
2. HER2 positive stomach cancer patients: define IHC 3+, or IHC 2+ and FISH/ISH
positive;
3. Previously received immune checkpoint inhibitors (such as anti-PD-1 antibodies,
anti-PD-L1 antibodies, anti-CTLA-4 antibodies, etc.), immune checkpoint agonists
(such as antibodies to ICOS, CD40, CD137, GITR, OX40 targets, etc.) , immune cell
therapy and other treatment of any immune mechanism for tumors;
4. In the first 14 days of randomization, there is still uncontrollable pleural
hydration and ascites after puncture drainage and other treatments. Imaging shows
that a small number of or medium chest and ascites patients can be selected for the
study;
5. Subjects have not received prior systemic therapy for locally advanced or metastatic
gastric adenocarcinoma or adenocarcinoma of the gastroesophageal junction. For
subjects who have received prior neoadjuvant/adjuvant chemotherapy or
chemoradiotherapy for curative intent, the time between disease progression and last
treatment should be at least 6 months;
6. There are significant clinical bleeding symptoms or clear bleeding tendencies within
1 month before the first administration, such as gastrointestinal bleeding,
hemorrhagic gastric ulcer, or vasculitis;
7. There are clinically active hemoptysis, active diverticulitis, abdominal abscess,
and gastrointestinal obstruction;
8. Any other malignant tumors have been diagnosed within 5 years before entering the
study, except for skin basal or squamous cell carcinoma, superficial bladder cancer,
cervical insitus, intraductal cancer and thyroid papilloma cancer that can be
treated locally and have been cured with clear medical records;
9. Known active or untreated brain metastases, meningeal metastases, spinal cord
compression, or leptomeningeal disease. However, subjects who meet the following
requirements and have measurable lesions outside the central nervous system are
allowed to enter the group: after treatment, the imaging is stable for at least 4
weeks before the start of the study treatment (if there is no new or expanded brain
metastasis), and systemic glucocortic hormone and anticonvulsive drug treatment has

therapy, and skin diseases that do not require systemic treatment (such as vitiligo,
psoriasis or hair loss);
12. There are clinical symptoms or diseases of the heart that are not well controlled,

examination: LVEF (left ventricular ejection fraction) <50%; (2) severe/unstable
angina pectoris; (3) randomized myocardial infarction within 6 months ; (4)
Clinically significant supventricular or ventricular arrhythmia requires treatment
or intervention; (5) Symptomatic congestive heart failure; (6) QTc>480 ms (QTc
interval is calculated in the Fridericia formula; if QTc is abnormal, it can be
separated by 2 minutes. The clock is detected 3 times in a row and takes its average
value);
13. Received the following treatments or drugs before the first administration:
1. Excessive surgery within the first 28 days (tissue biopsy required for
diagnosis and peripheral vein puncture central venous catheterization [PICC] /
infusion port implantation are allowed);
2. Immunosuppressive drugs have been used within the first 14 days, excluding

corticosteroids of the same physiological dose of the drug);
3. Inoculated with live attenuated vaccine within the first 28 days or within 60
days after the study period and the end of the research drug treatment;
4. Receive local anti-tumor treatment within the first 28 days (such as
radiotherapy or tumor embolization, etc.);
5. Received Chinese herbal medicine or Chinese medicine with anti-tumor
indications in the first 2 weeks;
14. Known allergies or intolerant to test drugs or their excipients; or a known history
of severe hypersensitivity reactions to other monoclon antibodies;

diarrhea or other gastrointestinal diseases that seriously affect drug use and
absorption;
16. Human immunodeficiency virus (HIV) infection or known acquired immunodeficiency
syndrome (AIDS), active hepatitis (hepatitis B, defined as HBV-DNA≥500 IU/ml;

17. Subjects who cannot comply with the test plan or cannot cooperate with the
follow-up;
18. Any conditions that, in the investigator's opinion, may put subjects treated with
the study drug at risks, or interfere with the evaluation of study drug or subject
safety, or the interpretation of results.
