A Study of Injection HB002.1T in Subjects With Solid Tumor

The objectives of this study are to evaluate the safety, tolerability, and pharmacokinetic profile of HB002.1T, a human immunoglobulin Fc fusion protein containing domain 2 and flanking sequence of vascular endothelial growth factor (VEGF) receptor-1 in subjects with solid tumor.

* Women and men of childbearing age must agree to take effective contraceptive measures after signing informed consent, during the study period and within 3 months after the last dose of HB002.1T, and the results of the pregnancy test for women of childbearing age must be negative;
* Subjects must voluntarily sign written informed consent;
* Subjects are able to communicate well with the investigator and are able to comply with research regulations.

Exclusion Criteria:

* Patients with confirmed active central nervous system metastasis and/or cancerous meningitis; but patients with central nervous system metastases who have received treatment and achieved clinical stability for 3 months before starting the study can be enrolled;
