Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Phase Ia - Dose escalation(Acceleration Stage); Phase Ia is an open, non-random, single-arm dose escalation design. Acceleration Stage: The initial increasing dose is 0.025 mg/kg, and the dose is increased in 100% increments. Each dose group will enroll 1 subject.	Biological: IBC0966; IBC0966 is an investigational product.
Experimental: Phase Ia - Dose escalation(3+3 Stage); Phase Ia is an open, non-random, single-arm dose escalation design. 3+3 Stage: The dose is increased in 30%-50% increments between adjacent dose groups, and the increment is determined by the investigator and the sponsor based on the safety data obtained in the previous period.Each dose group will enroll 3 to 6 evaluable subjects (evaluable: at least complete the DLT observation period), and this period continues until the maximum tolerated dose (MTD) is reached.	Biological: IBC0966; IBC0966 is an investigational product.
Experimental: Phase Ib - Dose extension; Phase Ib is an open, non-random, single-arm, multi-center research design. When phase Ia is transformed into 3+3 stage, a certain dose group meets the conditions for increasing the next dose group (after the DLT observation period of the last subject in the dose group has passed, the safety assessment of the current dose group will be completed) , The dose extension study of this dose group can be carried out, and 6 evaluable (evaluable: at least 2 cycles of dosing and observation) subjects with advanced malignant tumors who have failed standard treatments will be included in this dose group.
