Clinical Trial Summary

The goal of this interventional study is to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of BAT8010 for injection in patients with advanced or metastatic solid tumors, explore the maximum tolerable dose. Participants will be given one of below dose once every three weeks: 0.8mg/kg, 1.2mg/kg, 2.4mg/kg, 3.6mg/kg, 4.8mg/kg, 6.0mg/kg, 7.2mg/kg, 8.4mg/kg. The dose escalation follow adopt accelerated titration and "3+3" dose increasing rule.

• Must agree to take effective contraceptive methods to prevent pregnancy.

Exclusion Criteria:

• Previously received HER2 targeted drug therapy such as trastuzumab or pertuzumab, Trastuzumab Emtansine or Enhertu, and the treatment of topoisomerase I inhibitors (such as irinotecan), there were adverse event (AE) equal to or pass 3 levels that were determined to be treatment-related or drug related

• Primary central nervous system tumor or symptomatic central nervous system metastasis, meningeal metastasis or previous history of epilepsy. Patients with asymptomatic or symptomatic central nervous system metastasis who have achieved clinical control but are judged stable by the investigator can be included.

• Major surgery has been performed within 28 days before the first use of the study drug, or if it has been more than 21 days after surgery, but the postoperative complications are still continuing.

• Subjects who had severe infection within 4 weeks before the first administration, or had any symptoms and signs of active infection within 2 weeks before the first administration.

• Untreated or under treatment tuberculosis subjects, with a history of immune deficiency, or other immune deficiency diseases, or with a history of organ transplantation.

• Active hepatitis B virus infected, hepatitis C virus infected, Treponema pallidum antibody positive and Rapid plasma reagin ring card test (RPR) positive.

Except for atrial fibrillation or paroxysmal supraventricular tachycardia

• Patients who have a history of non-infectious pneumonia requiring glucocorticoid treatment or who currently have interstitial lung disease.

• There are any other serious potential diseases.

• Previous anti-tumor therapy (such as chemotherapy, endocrine therapy, targeted therapy, immunotherapy or tumor embolization) is less than 28 days from the first study administration.

• Therapeutic radiopharmaceuticals must be discontinued 8 weeks before the first study administration.

• Known allergy or intolerance to the study drug or its excipients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose-limiting toxicity (DLT)	Grade 5 toxicity; Hematological toxicity: Grade 4 alanine-aminotransferase(ALT) or aspartate-aminotransferase(AST) increase: AST or ALT>5 times upper limit of normal value(ULN), with = 2 levels of blood bilirubin increase; Hematological toxicity: Grade 4 neutropenia lasting>7 days. =Grade 3 neutropenia with fever (single body temperature>38.3 or continuous body temperature = 38 ?, more than 1 Hour). Grade 4 anemia. Grade 4 thrombocytopenia. = Grade 3 thrombocytopenia and lasting>7 days. = Grade 3 thrombocytopenia with bleeding; Other =Grade 3 non hepatic toxicity, non hematological toxicity.	3 weeks
Primary	maximum tolerated dose (MTD)	MTD was defined as the highest dose level of DLT observed in =1/6 subjects in a dose group during the DLT evaluation period	3 weeks
Secondary	Pharmacokinetic	Cmax	every cycle until 18 weeks (one cycle equals 3 weeks)]
Secondary	Immunogenicity	Presence of anti drug antibody (ADA)/Neutralizing antibodies (NAb) ADA, Nab	every cycle until 18 weeks, every 4 cycles after 18 weeks (one cycle equals 3 weeks), up to 1 year
Secondary	Objective response rate (ORR)	Refers to the proportion of patients whose tumors have shrunk to a certain amount and remained for a certain period of time, including CR and PR cases. Specifically divided into: 1.The ratio of patients with partial response (PR) or complete remission (CR) efficacy at the end of the first 6 cycles (18 weeks) of treatment. 2.The proportion of patients whose best response reached PR or CR during the entire study period.	through study completion, an average of 2 years
Secondary	Duration of remission (DoR)	DoR is defined as the time between the first assessment of objective remission of a tumor and death from any cause before the first assessment of Disease progression (PD) , reflecting the duration of ORR.	Through study completion, an average of 2 years
Secondary	Disease Control Rate (DCR)	The proportion of patients with reduced or stable tumors that remain for a certain period of time, including CR, PR, and Disease stability (SD) cases.	through study completion, an average of 2 years
Secondary	Progression free survival (PFS)	The time from the first administration to the occurrence of objective tumor progression or all cause death	through study completion, an average of 2 years
Secondary	Total survival period (OS)	The time from the date of first administration to the occurrence of death due to any cause. Subjects who were still alive at the time of analysis will use the date of their last contact as the deadline.	through study completion, an average of 2 years
