Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is a single-arm, open-label, multicenter, phase II clinical study to evaluate the clinical efficacy and safety of HLX10 monotherapy for the treatment of patients with unresectable or metastatic MSI-H or dMMR solid tumors who have progressed or intolerable after standard therapy.This study consists of three periods, screening period (28 days), treatment period and follow-up period (including safety follow-up, survival follow-up).Subjects can be enrolled into this study only if they meet inclusion criteria and do not meet exclusion criteria. The enrolled subjects will receive an intravenous infusion of HLX10 (3 mg/kg) once every 2 weeks until the loss of clinical benefit, death, intolerable toxicity, withdrawal of informed consent or other reasons as specified in the protocol, or up to the longest treatment duration-2 years (52 dosing periods) (whichever occurs earlier).

* There is at least one measurable lesion assessed by IRRC according to the requirements of RECIST version 1.1 (Appendix 1).

Note: measurable lesions cannot be selected from the previous radiotherapy sites. If the target lesion of the previous radiotherapy sites is the only one available lesion, the investigator is required to provide imaging data before and after significant progression of such lesion.

• Subjects must provide tumor tissues and blood samples for the determination of MSI, tumor mutational burden (TMB), PD-L1 expression level (if the test results of the above parameters by the central laboratory specified by this study are available, the subjects are allowed not to receive repeated tests).

Note: it is recommended to provide formalin fixed tumor tissue samples collected from non-radiotherapy sites within 6 months prior to the first dosing of investigational product, paraffin embedded tumor samples (preferred), or formalin fixed paraffin embedded tumor samples or unstained newly sliced serial sections (glass slides). Moreover, the corresponding pathological reports of the above samples must also be provided. Freshly collected samples, excision, core needle biopsy, resection, incision, punching or forceps biopsies are within the acceptable range (newly-obtained tissues preferred). The aspiration samples (i.e., lack of complete tissue structure and only cell suspension and/or cell smears are provided), brushing samples, cell precipitation samples from pleural or peritoneal effusion are not acceptable. The requirements for tissue samples are provided in laboratory operating manual in detail.

* Life expectancy ≥12 weeks;
* Negative HBsAg; patients with positive HBsAg or HBcAb test results can be enrolled only if Hepatitis B virus (HBV) DNA test results are negative.

11.Negative HCV antibody; patients with positive HCV antibody or HCV-RNA test results can be enrolled only if ALT and AST are CTCAE v4.03 ≤ grade 1 (i.e., ≤ 3×ULN); subjects concurrently infected with hepatitis B and hepatitis C are excluded.
* Normal function of main organs, and the following criteria are met (within the 14 days before the first injection of investigational product, patients have not received the treatment with blood transfusion, albumin, recombinant human thrombopoietin or colony stimulating factor (CSF)):
* Female subjects must meet the following criteria:

① Menopause (defined as no menstruation for at least one year, and no other confirmed reasons other than menopause), or② Received surgical sterilization (ovariectomy and/or hysterectomy), or③ Subjects who are able to bear or father a child must meet the following criteria:
* Serum pregnancy test must be negative within 7 days before the first dosing, and
* Agree to use contraceptive methods with an annual failure rate of \< 1% or maintain sexual abstinence (avoid heterosexual intercourse) (from the signing of informed consent form to at least 120 days after the last dose of investigational product) (contraceptive methods with an annual failure rate of \< 1% include bilateral tubal ligation, male sterilization, correct use of hormonal contraceptives which may inhibit ovulation, hormone-releasing intrauterine device and copper intrauterine device), and
* Breast-feeding is not allowed.
* Male subjects should meet the criteria below: agree to maintain sexual abstinence (avoid heterosexual intercourse) or use contraceptive methods, with requirements detailed below: if the partners of male subjects have childbearing potential or become pregnant, male subjects must maintain sexual abstinence or use condoms to prevent drug exposure to embryos during administration period of investigational product and within at least 120 days after after the last dose of investigational product. The reliability of sexual abstinence should be evaluated based on the duration of clinical studies, preference of the subjects and daily life style.
