a clinical trial to evaluate the effect of iae0972 in patients with advanced malignant solid tumors.

Conditions: Advanced Malignant Solid Tumor

Summary: this is a phase i/iia clinical trial to evaluate the safety,tolerability,pharmacokinetics and preliminary effectiveness of iae0972 in patients with advanced malignant solid tumors.

the study includes three phases: dose escalation (phase ia), dose extension (phase ib), and clinical exploration (phase iia).first, the phase ia dose escalation will be carried out. after finishing the phase 1a dose escalation, the phase ib dose extension study can be carried out in the mtd dose which is obtained from phase 1a . after phase ia \&1b are completed and rp2d is obtained, phase iia clinical exploratory research can be carried out.

of investigational product. 3. international normalized ratio of prothrombin time (inr) ≤ 1.5 × upper limit of normal (uln), activated partial thromboplastin time (aptt) ≤ 1.5 × uln. 4. hemoglobin (hgb) ≥ 90 g/l. 5. aspartate aminotransferase (ast) and alanine aminotransferase (alt) ≤ 3.0 × uln; for patients with hepatic metastases, alt and ast ≤ 5.0 × uln. 6. total bilirubin ≤ 1.5 × uln, except patients with gilbert's syndrome, who may enroll if the conjugated bilirubin is within normal limits. 7. serum creatinine \< 1.5 × uln, or estimated creatinine clearance ≥ 60 ml/min as measured or calculated using the cockcroft-gault formula. 9. female patients of childbearing potential (not surgically sterilized and between menarche and 1- year postmenopause) must have a negative serum or urine pregnancy test performed within 7 days prior to the initiation of investigational product administration. further, female patients of childbearing potential must agree to use highly effective contraceptive measures (include hormonal contraceptives, intrauterine device or system, vasectomy, or tubal ligation) from the time of consent through 3 months after discontinuation of investigational product administration. 10. male patients with partners of childbearing potential must use barrier contraception. in addition, male patients should also have their partners use another method of contraception from the time of consent through 3 months after discontinuation of investigational product administration. exclusion criteria: * 1. known hypersensitivity (≥ grade 3) to recombinant proteins or any excipient contained in the drug or vehicle formulation for iae0972. 2. history of another malignancy or a concurrent malignancy. exceptions include patients who have been disease free for two years, or successfully treated for non-melanoma skin cancer, localized prostate cancer (gleason score \< 6) or carcinoma in situ, for example cervical cancer in situ, are eligible. 3. treatment with any systemic anti-neoplastic therapy, radiation therapy or investigational therapy within 4 weeks prior to the initiation of investigational product administration, with the following exceptions: 1. nitrosourea or mitomycin c should be within 6 weeks prior to the initiation of investigational product administration. 2. oral fluoropyrimidines and small molecule targeted drugs should be within 2 weeks or 5 half-lives (whichever is later) prior to the initiation of investigational product administration. 4. history of trauma or major surgery within 4 weeks prior to the initiation of investigational product administration. 5. treatment with corticosteroids (prednisone ≥ 10 mg per day or equivalent) or other immune suppressive drugs within the 14 days prior to the initiation of investigational product administration. steroids for topical, ophthalmic, inhaled or nasal administration are allowed. 6. treatment with immunomodulatory agents, including but not limited to thymosin, interleukin-2 and interferon within 14 days prior to the initiation of investigational product administration. 7. vaccination with any live virus vaccine within 4 weeks prior to the initiation of investigational product administration. 8. history of prior allogeneic bone marrow, stem-cell or solid organ transplantation. 9. active brain or leptomeningeal metastases. patients with brain metastases are eligible if these have been treated and mri or ct shows no evidence of progression for at least 8 weeks after treatment completion and within 4 weeks prior to the initiation of investigational product. patients are not eligible if they required high doses of systemic corticosteroids that could result in immunosuppression (\>10 mg/day prednisone equivalents) for at least 2 weeks prior to the initiation of investigational product. 10. evidence of active viral, bacterial, or systemic fungal infection requiring parenteral treatment within 7 days prior to the initiation of investigational product. patients requiring any systemic antiviral, antifungal, or antibacterial therapy for active infection must have completed treatment no less than one week prior to the initiation of investigational product. 11. known history of hepatitis b or hepatitis c infection or known positive test for hepatitis b surface antigen, hepatitis b core antigen, or hepatitis c polymerase chain reaction (pcr). 12. known positive testing for human immunodeficiency virus (hiv) or history of acquired immune deficiency syndrome (aids). 13. clinically significant pulmonary compromise, including a requirement for supplemental oxygen use to maintain adequate oxygenation. 14. history of clinically significant cardiovascular disease including but not limited to: 1. myocardial infarction or unstable angina within the 6 months prior to the initiation of investigational product. 2. stroke or transient ischemic attack within 6 months prior to the initiation of
