Study of LM-102 in Subjects in Advanced Tumors

- 1. Subjects who are fully informed of the purpose, nature, method and possible adverse reactions of the study, and are willing to participate in the study and sign the informed consent document prior to any procedure; 2. Aged between 18 to 75 years old, male or female when sign the informed consent form (ICF); 3. Subjects must have histological or cytological confirmation of recurrent or refractory CLDN18.2-positive advanced solid tumors including but not limit to gastric and gastroesophageal junction adenocarcinoma, pancreatic carcinoma, biliary tract carcinoma, colorectal carcinoma, ovarian carcinoma; 4. Subjects are intolerable for available standard therapy or there is no standard available therapy; 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 with no deterioration within 2 weeks from the first dose; 6. Life expectancy ≥ 3 months; 7. Tumor samples have CLDN18.2 membranous staining in ≥ 1% of the tumor cells with any intensity as determined by central immunohistochemistry (IHC) testing. As such, all patients must be able to provide formalin fixed and paraffin embedded archived tumor tissue samples obtained ≤ 3 years prior to screening;

1. Subjects who have difficulties in venous blood collection or history of dizziness with blood or needles;

2. Childbearing potential female (see Appendix 3 Contraceptive Methods) who have positive pregnancy test or are breast feeding;

3. Subjects who known to be allergic to LM-102 or any of its excipients;

4. Exposure to any IMP, or participate in any other clinical trial within 28 days prior to 1st dosing LM-102;

5. Subjects with prior anti-tumor within 28 days prior to 1st dosing of LM-102, including radiotherapy (except palliative radiotherapy, beyond 14 days prior to 1st dosing of LM-102, and the toxicity has been recovered as assessed by investigator.), chemotherapy, biotherapy, endocrine therapy and immunotherapy, etc. However, the application of other small molecular targeted drugs and the herbal medicine with anti-tumor indication longer than 14 days or 5 half-life periods of the drug (whichever is longer) is acceptable;

6. Subjects who have received surgical or interventional treatment within 28 days prior to 1st dosing LM-102, excluding operations or surgeries that can be recovered within 14 days prior to 1st dosing LM-102, and have been recovered by the investigator's assessment, e.g., tumor biopsy, puncture, palliative operation, rectal/gastrostomy, etc.;

7. Subjects who have concurrent administration of anticoagulation agents or vitamin K antagonists;

8. Subjects who have concurrent administration of therapeutic doses of heparin (prophylactic doses are acceptable);

9. Subjects who have gastric outlet obstruction, persistent recurrent vomiting or uncontrolled/significant gastrointestinal hemorrhage, symptomatic peptic ulcer, or major bleeding risk in other parts of the body within 28 days prior to 1st dosing LM-102;

10. Central nervous system metastasis or meningeal metastasis with clinical symptoms, or other evidence that the subject's central nervous system metastasis or meningeal metastasis has not been controlled, and the investigator judges it to be unsuitable for inclusion;

11. Subjects who have symptomatic congestive heart failure, history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable angina pectoris, uncontrolled hypertension (Blood pressure still ≥ 140/90 mmHg after drug treatment), clinically significant cardiac arrhythmia or myocardial infarction within the past 6 months, etc.;

12. Any adverse events from prior anti-tumor therapy have not yet recovered to ≤ grade 1 of CTCAE v5.0 (Except for some grade 2 toxicity that the investigator judges that there is no safety risk, such as alopecia, and other long term ≤ grade 2 toxicities which would not impact the administration of LM-102 and safety evaluation);

13. Subjects who have uncontrolled or severe illness, including but not limited to ongoing or active infection requiring antibiotics;

14. Subjects who have a history of immunodeficiency disease, including other acquired or congenital immunodeficiency diseases, or organ transplantation, or allogeneic bone marrow transplantation, or autologous hematopoietic stem cell transplantation;

15. HIV infection, active HBV infection (HBV DNA exceeds the ULN), active HCV infection (HCV RNA exceeds the ULN);

16. Male and female subjects who are unwilling to use adequate contraceptive methods (e.g, concomitant use of a spermicidal agent, barrier contraceptive, or/and intrauterine contraceptive during the study and for at least 6 months after the last dose of LM-102. (See Appendix 3 for contraceptive methods);

17. Subjects who have psychiatric illness or social situations that would preclude study compliance;

18. Subjects who have another active malignancy which is likely to require treatment;

19. Subject who is determined as not eligible to participate in this study by the investigator.
