• - Expected survival time ≥ 3 months.

• - Voluntarily participate in this clinical trial and sign a written informed consent.

• - Previous anti-tumor therapy (chemotherapy, radiotherapy, targeting, traditional Chinese medicine, other immunotherapy) requires eluting for 28 days.

• - The adverse effects of previous antitumor therapy were resolved to grade 0-1 before the screening period (as determined by NCI CTCAE 5.0; Except for toxicity, such as hair loss, which the investigator determined did not pose a safety risk to the subject)

  Exclusion Criteria:

  - no measurable lesions, such as pleural or pericardial exudates, ascites, etc. - choroidal melanoma.

• - previous treatment with HDAC inhibitors (including cedaramide, romidepsin, vorinostat, bellistat, panobinostat, etc.) - history of interstitial lung disease or pneumonia requiring oral or intravenous steroids.

• - previous vaccination or planned vaccination with live vaccines (seasonal influenza vaccine without live vaccines is allowed), major surgery within 30 days before the first study treatment.

• - active infection [active bacterial, viral, fungal, mycobacterial, parasitic infections or other infections (excluding fungal infections of the nail bed) within 4 weeks before the screening period, or any major infection event requiring intravenous antibiotic therapy, or targeted antiviral therapy, or hospitalization; Active hepatitis is defined as HBsAg positive with HBV DNA≥500 IU/ml or HCV antibody positive with HCV copy number > the upper limit of normal], or persistent fever within 14 days before screening.

• - history of immunodeficiency, including positive HIV testing, or other acquired, congenital immunodeficiency diseases, or history of organ transplantation.

• - uncontrolled cardiovascular disease; history of clinically significant QT prolongation, or screening period > 470 ms for females and > 450 ms for males.

• - positive baseline pregnancy test in female subjects who are pregnant or lactating or fertile females; or subjects of childbearing age who are unwilling to take effective contraceptive measures for at least 180 days during study participation and after the last dose of study drug.

• - According to the investigator 's judgment, there are concomitant diseases that seriously jeopardize the subject' s safety or affect the subject 's completion of the study (e.g., severe hypertension ≥ 180/110 mmHg, uncontrolled diabetes, thyroid disease, Hypertriglyceridemia ≥ grade 2, etc.) - History of definite neurological or psychiatric disorders, including epilepsy or dementia.

• - Any condition that, in the opinion of the investigator, would make participation in this study inappropriate.
