简要总结
This is a multi-center, open-label, dose-escalation and cohort-expansion phase I clinical study to evaluate the safety and tolerability, pharmacokinetics profile, efficacy and immunogenicity of IMM2520 in subjects with advanced solid tumors.
详细描述
IMM2520 is administered via intravenous infusion once week of cycle 1- 12 (4 weeks per cycle).
The accelerated titration method and the traditional "3+3" method will be adopted to determine the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D) in dose-escalation phase.
Once the RP2D is determined, Simon's two-stage design will be used to explore for each specific tumor cohort.adenocarcinoma/esophageal cancer, urothelial cancer, and/or others.

- •There is at least one measurable tumor lesion (refer to RECIST 1.1), defined as the longest measurable diameter of non-lymph node lesions by imaging (CT/MRI) ≥10 mm or the short diameter of a single pathological lymph node lesion ≥15 mm; at least one evaluable tumor lesion is needed in the dose-escalation phase.

- •Prothrombin time (PT) ≤ 1.2 × ULN, activated partial thromboplastin time (APTT) ≤ 1.2 × ULN; international normalized ratio (INR) ≤ 1.2 (unless the subject is receiving warfarin therapy). If the subject is taking oral anticoagulant therapy, the dose should be stable for 2 weeks; if the subject is taking oral warfarin, the subject's INR must be ≤ 2.5 without hemorrhage.
- •Creatinine clearance (Cr) > 30 mL/min (Cockcroft and Gault Equation).
- •Left ventricular ejection fraction (LVEF) ≥ 40%;
- •Previously treated toxicities have recovered to Grade 1 [as per NCI CTCAE 5.0 grading criteria] (except toxicities which have no safety risk at the discretion of the investigator, such as alopecia, neurotoxicity ≤ Grade 2 caused by chemotherapeutic drugs, etc.).
- •Females with childbearing potentials must be tested negative for serum pregnancy test during the screening period before receiving the first administration of IMM2520; any female patient with childbearing potential must agree to take effective contraceptive measures during the entire study and within 3 months after study completion. A patient is considered to have childbearing potential if he/she is biologically capable of having children and has a heterosexual sex life.
排除标准
- •A subject meeting any of the following criteria must be excluded from the study.
- •Subjects are enrolled into another clinical study continuously, unless it is an observational, non-interfering clinical study or in the follow-up period of an interfering study.
- •Treatment with the last systemic chemotherapy within 3 weeks; treatment with hormone therapy and small-molecule target therapy within 2 weeks; palliative radiation treatment for non-target lesions within 2 weeks; treatment with non-specific immunomodulatory therapy within 2 weeks prior to the first administration.
- •Subjects with active central nervous system (CNS) metastases (Subjects with stable treated central nervous system [CNS] lesions who are off corticosteroid therapy for at least 2 weeks are not considered active).
- •Subjects who have received previous treatment with > 1 PD-1 or PD-L1 inhibitors, such as pembrolizumab, nivolumab, atezolizumab or durvalumab.
- •Subjects who have received previous treatment with anti-CD47 monoclonal antibody fusion protein.
- •Subjects diagnosed with other malignancies within 2 years before the first dose with exceptions: a. cervical carcinoma in situ or basal or squamous cell carcinoma of the skin underwent radical resection; b. second primary carcinoma underwent radical resection and without recurrence within 5 years; c. double primary cancers that can benefit from this study in the opinion of the investigator.
- •Subjects who received prior allogeneic hematopoietic stem cell transplant or other organ transplants with acute or chromic GVHD（graft versus host disease） requiring the long-term immunosuppressive therapy before 6 months of treatment.
- •Subjects with active autoimmune diseases requiring systemic treatment (with glucocorticoids or immunosuppressive drugs) in the past 2 years with exceptions of hormone replacement therapy for thyroid disease, adrenal or pituitary insufficiency disease.
- •Concurrent medical condition requiring systemic corticosteroids (prednisone daily dose > 20 mg or equivalent dose) within14 days prior to first dose of the investigational product.
- •Subjects who underwent a major surgery within 4 weeks prior to the first dose or planned to undergo a major surgery in 3 months after receiving the investigational drug (excluding catheterization, peripherally inserted central catheter, etc.).
