Description of intervention(s) / exposure
Treatment: Drugs - RC118 for injection

Experimental: RC118 for injection - Part A (Dose Escalation): RC118 will be administered through IV infusion at the various dose levels, including 0.25, 0.5, 1.0, 1.5, 2, 2.5, and 3 mg/kg, 1-12 subjects for each dose level.
Part B (Dose Confirmation): RC118 will be administered at up to two dose levels, which is equal or lower than MTD/MAD, through IV infusion. Each dose level contains 3-6 subjects.


Treatment: Drugs: RC118 for injection
RC118 will be administered intravenously (IV) on Day 1 of every 14-day cycle.

Eligibility
Key inclusion criteria
1. Patients must be able to provide documented voluntary informed consent.

2. Male or female patient = 18 years and = 75 years.

3. Eastern Cooperative Oncology Group (ECOG) performance status (PS) score 0 or 1.

4. The expected survival period exceeds 12 weeks.

5. At least one target lesion that can be measured per Response Evaluation Criteria in
Solid Tumours (RECIST) v1.1.

6. Histologically documented, incurable, unresectable locally advanced or metastatic
tumours that are intolerable or refractory to standard therapies.

7. Patients agree to provide pre-treatment archived /biopsy tumour samples for
retrospective Claudin 18.2 test. Archival tumour tissue should be from the most recent
timepoint before entering the trial. In addition, archived samples obtained out of the
screening are acceptable if it is discussed and approved by the Investigator and
Sponsor in advance. Only when archived samples cannot be obtained, the biopsy will be
considered at screening. Fresh tumour biopsies will NOT be considered if significant
risk procedures are required with the discretion of Investigator.

8. Adequate bone marrow, liver, and renal function defined as: absolute neutrophil count
(ANC) = 1.5 × 109/L, platelet = 100 × 109/L, haemoglobin = 90 g/L, serum total
bilirubin = 1.5 × upper limit of normal (ULN), ALT, AST or ALP = 2.5 × ULN (= 5 × ULN
when there is known liver metastasis), serum creatinine = 1.5 × ULN, INR = 1.5 × ULN,
APTT = 1.5 × ULN.

9. Willingness to avoid pregnancy or fathering children based on the criteria below:

- Female patients of childbearing potential and male patients with partners of
childbearing potential treated with RC118, must agree to use a highly effective
form(s) of contraception during study and within 6 months after the last dose.
Those methods include but not limited to combined (oestrogen and progestogen
containing) hormonal contraception, intrauterine device, intrauterine
hormone-releasing system, bilateral tubal occlusion or vasectomized partner (on
the understanding that this is the only one partner during the whole study
duration), and sexual abstinence.

- Females of non-childbearing potential (e.g., surgically sterile with a
hysterectomy and/or bilateral oophorectomy or chemically sterile or = 12 months
of amenorrhea in the absence of chemotherapy, anti-oestrogens, or ovarian
suppression). Those females do not need to undergo pregnancy test.
Minimum age
18 Years
Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Women who are pregnant or breastfeeding.

2. Diagnosed active hepatitis B infection (defined as positive of hepatitis B surface Ag
and hepatitis B DNA=500IU/ml), active hepatitis C infection (defined as presence of
hepatitis C RNA), and human immunodeficiency virus infection (defined as positive HIV
test) during the screening period.

3. Received vaccines within 4 weeks prior to administration or plan on receiving any
vaccine during the study.

4. Subjects with a history of other acquired/congenital immunodeficiency diseases or
organ transplantation.

5. Patients have history of targeted therapy of Claudins, or participated in other
clinical trials and received investigational product within 4 weeks before the first
administration of study drug.

6. Allergic constitution or allergic to known research drug active ingredients or
excipient.

7. Patients who are under the treatment of anticoagulant drugs (e.g., warfarin, apixaban,
and heparin). Patients using prophylactic doses of heparin (e.g., LMWH) is eligible in
the study.

8. Patients undergoing any anti-tumour therapy, including surgery, chemotherapy,
radiotherapy and biological therapy, within 4 weeks prior to the first administration
of study drug, or palliative radiotherapy for bone/other solitary metastases within 2
weeks prior to the first administration of study drug.

9. Previous adverse reactions resulting from previous anti-tumour therapies, which have
not returned to Grade 0 or 1 according to NCI-CTCAE v5.0 (except alopecia) at
screening.

10. There are clinical symptoms of fluid in the third space (e.g., large amounts of
pleural fluid or ascites) that cannot be controlled by drainage or other therapies.

11. A clinically significant active infection judged by the investigator.

12. Comorbidities that may seriously endanger the patient's safety or affect the
completion of the study, such as gastrointestinal bleeding (within 4 weeks prior to
the screening period), peptic ulcer, intestinal obstruction, intestinal paralysis,
interstitial pneumonia, pulmonary fibrosis, kidney failure, and uncontrolled diabetes.

13. QTc interval > 480 ms in both male and female (based on the mean value of the
triplicate screening ECGs); family or personal history of long/short QT syndrome,
History of ventricular arrhythmia deemed clinically significant by the investigator,
or currently receiving antiarrhythmic drug treatment, or implantation of arrhythmia
defibrillation device.

14. History of myocardial infarction within 6 months prior to the screening period, severe
or unstable angina pectoris, coronary or peripheral artery bypass grafting, heart
failure = 3 (New York Heart Association), or uncontrolled hypertension.

15. Patients with known current alcohol dependence or drug abuse.

16. Patients with a long-term history of systemic steroid therapy. Patients with
short-term (= 7 days) use and drug withdrawal > 2 weeks are eligible.

17. History or presence of uncontrolled primary brain tumours (e.g., leptomeningeal
carcinomatosis) or metastatic brain tumours, unless considered stable by the
Investigator and local therapy was completed.

18. History or presence of Grade = 2 peripheral neuropathy.

19. History or presence of uncontrolled mental illness at the discretion of the
Investigator, which may place the participant at increased risk of safety/tolerability
issues.

20. The patient is, in the opinion of the investigator, expected to be non-compliant with
critical trial procedures and is not willing or able to adhere to the trial
requirements in the future.

21. Patients who are not appropriate for this clinical trial at the discretion of the
investigator.
