Description of intervention(s) / exposure
Treatment: Drugs - IMM47

Experimental: Dose escalation - It's a dose escalation to identify the Maximum Tolerated dose (MTD) , recommended Phase II dose (RP2D) of IMM47, an accelerated titration method and the traditional "3+3" design method will be adopted. IMM47 will be sequentially escalated at the dose of 5 µg/kg,50 µg/kg, 250 µg/kg,1.0 mg/kg,3.0 mg/kg and 5.0 mg/kg or higher dose levels, administered via intravenous infusion every 2 weeks in 28-day treatment cycles.

The duration of the infusion is 120 min (± 10 min) for the 1st infusion and 60 min (± 5 min) for subsequent infusions.


Treatment: Drugs: IMM47
IMM47 is humanized mAb targeting CD24 to be administered via intravenous infusion every 2 weeks in 28-day treatment cycles.

5. The intervals for discontinuing the last anti-tumor therapy prior to the first dose of the investigational product are required as follows Subjects who previously received chemotherapeutic agents must have discontinued the drug for more than 3 weeks.

Subjects who previously received small-molecule targeted therapy must have discontinued treatment for more than 2 weeks or 5 half-lives of the drug (whichever is longer).

Subjects who previously received monoclonal antibodies (eg. CD20 antibody, PD-1/PD-L1 antibody) must have discontinued the treatment for more than 4 weeks.

Subjects who previously underwent palliative radiation therapy must have discontinued the treatment for more than 2 weeks.
6. With suitable organ and hematopoietic functions:

Neutrophil count =1.5 × 109/L. (no growth factor therapy within 4 weeks prior to Screening).

Platelet count =100 × 109/L ; for subjects with HCC, platelet count =75 ×109 /L Hemoglobin = 90 g/L (subjects may be transfused >2 weeks before screening, but should not be transfusion-dependent).

Total Bilirubin (TBIL) = 1.5 × ULN (or = 3.0 × ULN if subject has a documented history of Gilbert's syndrome or liver metastases).

Both aspartate transaminase (AST) and alanine transaminase (ALT) = 2.5 × ULN (or both AST and ALT = 5.0 × ULN if subject has a documented history of liver metastases).

International normalized ratio (INR) =1.5 × ULN, or activated partial thromboplastin time (APTT) = 1.5× ULN.

Left ventricular ejection fraction (LVEF) = 50%. Serum creatinine =1.5 × ULN or creatinine clearance (CrCl) = 40 mL/min (Cockcroft and Gault Equation) if serum creatinine >1.5 ULN. Lower calculated creatinine clearance values may be allowed at the Investigator's discretion and in consultation with the Medical Monitor and Sponsor
7. Adverse events associated with previous anti-tumor therapies should have recovered to = Grade 1 (CTCAE version 5.0) (except for toxicities not considered a safety risk such as alopecia, skin pigmentation, and other non-clinically significant abnormalities).
8. Female subjects (based on sex assigned at birth) of childbearing potential must be tested negative for serum pregnancy test during the screening period before receiving the first administration of IMM47; any female subject of childbearing potential must agree to take effective contraceptive measures during the entire study and within 6 months after last dose of the investigational product. A subject is considered to have childbearing potential if he/she is biologically capable of having children and has a heterosexual sex life. Female subjects meeting at least one of the following criteria are deemed to be without childbearing potential:

Has undergone hysterectomy or bilateral oophorectomy Medically confirmed with ovarian failure Medically confirmed as postmenopausal (menstruation has stopped for 12 consecutive months not for pathological or physiological reasons)

Acceptable forms of contraception for female subjects are:

Should not have sexual intercourse or genital contact with a male partner, or use a method of birth control for the duration of the study participation and for 6 months last dose of the investigational product.

Must agree to use one form of contraception, including sterilization, combined estrogen and progestogen containing hormonal contraception pills or an intravaginal, transdermal, or intrauterine device.

Intrauterine hormone-releasing system. Bilateral tubal occlusion (surgical procedure that involves blocking by cutting, burning or removing sections, or placing clips of the fallopian tubes to prevent the ovum [egg] from being fertilized).

A vasectomized partner (surgical procedure that involves cutting and sealing the tubes used to transport semen from the testicles to the penis, thereby rendering infertility).

Male subjects with female partners of childbearing potential are eligible to participate if they agree to ONE of the following for the duration of the study and until 90 days after the last dose of the study treatment:

Are abstinent from penile-vaginal intercourse as their usual and preferred lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent.

Agree to use a male condom and have their partner use a contraceptive method with a failure rate of <1% per year as described below when having penile-vaginal intercourse with a WOCBP who is not currently pregnant.

In addition, male subjects must refrain from donating sperm for the duration of the study and for 90 days after the last dose of study treatment.

Male subjects with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile penetration for the duration of the study and until 90 days after the last dose of the study treatment.
9. Subjects who voluntarily sign the informed consent form, understand the study, and are willing to comply with the protocol, and are able to complete all trial procedures.
10. At least one measurable or evaluable tumor lesion. For solid tumor: Measurable lesion according to RECIST version 1.1 is defined as tumor lesions =10 mm in longest diameter or pathologic node = 15 mm in short axis.
11. For both phase Ia and Ib, subjects must agree to provide archived tumor tissue samples for CD24 IHC expression assessment by the central laboratory. In the setting where archival material is unavailable or unsuitable for use (e.g., recently diagnosed subjects or diagnosed with fine needle aspiration), the subject must consent and undergo fresh tumor biopsy (biopsy at acceptable risk as judged by the Investigator). The requirement for fresh biopsy collected from a given subject could be waived after the discussion with the Sponsor, if the tumor tissues are not safely accessible as determined by the Investigator, or the tumor biopsies have to be obtained from sites that require significant risk procedures.
