- Target Recruitment
- 93
- Voluntarily participating in this clinical study and signing a written informed consent form and being able to comply with clinical visits and study-related procedures.
- Male or female subjects ≥ 18 and ≤ 75-year age when signing the informed consent form.
- Expected survival time of not less than 3 months (as judged by the investigator)
- Subjects with histologically or cytologically confirmed advanced malignant solid tumors, ie, recurrent or metastatic, advanced solid tumors, who have failed the standard therapy or who are not suitable for standard therapy at this stage.
- Subjects are able to provide tumor tissue samples (archived tumor tissue within one year as much as possible or fresh specimens of core needle aspiration).
- According to RECIST V1.1 criteria, (dose escalation phase), at least one evaluable tumor lesion; (dose expansion phase) at least one measurable tumor lesion (tumor lesions located in the previously radiotherapy area or other localized regional treatment area are generally not considered measurable unless the lesion has clearly progressed or persists after three months of radiotherapy).
- Patients are required to have injectable lesions that meet the current dosage administered in the dose level. Superficial lesions are preferred, and deep lesions that can be injected under the ultrasound/CT guidance [injectable lesions cannot have previously been treated with radiotherapy or other intratumoral injections, and lesions with a high risk of bleeding (eg, adjacent to large blood vessels, the presence of large blood vessels in the tumor or vascular encasement) should not be considered injectable lesions].
- Eastern Cooperative Oncology Group (ECOG) physical performance score 0-1.
- Bone marrow reserve and organ function must meet the following requirements (no blood transfusion and no supportive treatment with blood components or granulocyte colony cytokines within 14 days before the first treatment).
Subjects with any of the following conditions are not eligible for this study:
-
Received or are receiving any anti-CD40 and/or CD137 therapy.
-
Subjects who have received or plan to receive allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation/bone marrow transplantation.

Used immunomodulatory drugs within 14 days before the first dosage of study drug, including but not limited to thymosin, interleukin-2, interferon, etc.
-
Received systemic corticosteroids (prednisone > 10 mg/day or equivalent dosage of similar drug) or other immunosuppressive agents within 14 days before the first dosage of study drug (except for the following: topical, ocular, intra-articular, intranasal, and inhaled corticosteroids are allowed; short-term use of corticosteroids for prophylaxis, eg, to prevent contrast agent from allergy).
-
Received anti-tumor therapy such as systemic chemotherapy, radiotherapy, targeted therapy, endocrine therapy, biological therapy and immunotherapy within 4 weeks before the first dosage of study drug, except for the following items: nitrosourea or mitomycin C within 6 weeks before the first dosage of study drug; oral fluoropyrimidines, small-molecule targeted drugs and traditional Chinese medicines with anti-tumor indications within 2 weeks before the first dosage of study drug; local palliative radiotherapy within 2 weeks before the first dosage of study drug;
-
Received other unmarketed study drugs or treatments within 4 weeks before the first dosage of investigational drug.
-
Received major organ surgery (excluding diagnostic needle biopsy treatment) or significant trauma within 4 weeks before the first dosage of study drug, or the need for elective surgery during the study.
-
Serious wounds/ulcers/fractures that cannot be healed within 4 weeks before the first dosage of study drug.
-
The adverse events caused by previous anti-tumor therapy have not recovered to CTCAE 5.0 Grade ≤ 1 before the administration (except for toxicity that is judged by the investigator to have no safety risk, such as alopecia, Grade 2 peripheral neurotoxicity and stable hypothyroidism with hormone replacement therapy).
-
Metastases to central nervous system or metastases to meninges.
-
History of other malignancy within 5 years of the enrollment (except for the following neoplastic diseases: adequately treated papillary thyroid carcinoma, cervix carcinoma in situ, basal or squamous cell skin cancer, or ductal carcinoma in situ of the breast treated with radical surgery).
-
Active infection requiring systemic intravenous anti-infective therapy or fever of unknown origin exceeding 38℃ at enrollment.
-

- Treponema Pallidum infection (TP-Ab positive)
- Subjects with known active tuberculosis (TB)
-
History of serious cardiovascular and cerebrovascular diseases, including but not limited to:
- Subjects with severe heart rhythm or conduction abnormalities, such as ventricular arrhythmia requiring clinical intervention, II-III degree atrioventricular block.

Group Intervention Description Experimental IMB071703 injection Part A: Dose escalation phase Six dose levels of IMB071703 injection are planned in Part A, 1 subject in the first dose level (accelerated titration design), 3 subjects in the 2nd through 6th dose levels separately (conventional Fibonacci 3+3 design). 19 to 33 subjects are expected to enroll. Part B: Dose/cohort expansion phase 1 to 2 dose levels of subjects with 1 to 2 tumor types are tentatively planned; a total of up to 15 subjects are included in each dose level for each tumor type, 15 to 60 subjects are expected to enroll.
