Exclusion Criteria:

1. Have a history of allergies in the past, and known to be allergic to CAN1012 injection or any of its components.

2. Have received TLR7/8 agonists in the past (except for topical dermal medications).

3. A history of another malignancy within the past 3 years that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin that has undergone curative therapy, or in situ cervical cancer.

"4. Unstable/inadequate cardiac function defined as follows:

1. New York Heart Association Class 3 or 4 congestive heart failure

Note: Subjects who have been vaccinated against Hepatitis B and who are positive only for the Hepatitis B surface antibody are permitted to participate inthe study.

6. Participated in a clinical study of an investigational agent within 4 weeks of screening.

7. Have received chemotherapy, radiotherapy, biological therapy, endocrine therapy, targeted therapy, immunotherapy and other anti-tumor therapy within 4 weeks before the first administration of the research drug [among them, the following provisions are: nitrosourea (such as carmustine, lomustine, etc.) or mitomycin C is within 6 weeks before the first administration of the research drug; Oral fluorouracil, small molecule targeted drugs are 5 half-lives (whichever is longer) for 2 weeks before the first administration of the study drug or the known drug; Traditional Chinese medicines with antitumor indications are within 2 weeks before the first administration of the study drug].

8. Has an active infection requiring systemic therapy within 4 weeks before the first dose of the drug under study, including but not limited to complications of infection that require hospitalization, bacteremia, severe pneumonia, etc.

9. Patients with symptoms or who have undergone radiation therapy or surgery within 3 months prior to the first administration of the study (those with brain metastases and instability shall not be included).

10. Injections of primary or metastatic lesions should be avoided in the central nervous system, thoracic cavity, heart and large blood vessels, liver, lungs, spleen and pancreas.

11. Unresolved toxicities from prior therapy, defined as having not resolved to Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 (v5.0) Grade 0 or 1, with exception of endocrinopathies from prior therapy, alopecia, and vitiligo.
