Gentuximab Injection	Experimental	Patients are assigned to a dose level at the time of study entry and scheduled to receive i.v. of a single dose. The patient enter the subsequent multiple dose i.v. in a 7-day cycle if no DLT in 21 days after the first dose. The study period of each subject will be up to 4 cycles until the tumor progression or unacceptable toxicity. The MTD will be determined by assessing DLT in each cohort from cohort 1 to 6, using a 3+3 dose escalation model. Cohort A begin at 4mg/kg IV and the dose escalated in separate cohorts from 8mg/kg IV, 12mg/kg IV，16mg/kg IV and 20mg/kg IV. If there is no DLT observe in any of these 3 patients in 7 weeks, then the trial proceeds to enroll 3 patients into the next higher dose cohort. If one subject develops a DLT at a specific cohort, an additional 3 patients are enrolled into that same dose cohort. Development of DLTs in more than 1 of 6 patients in a specific dose cohort suggests that the MTD has been exceeded, and further dose escalation is not pursued.	Drug: Gentuximab Injection

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Dose-limiting toxicities (DLT)	Number of Participants With One or More Drug-Related Adverse Events (AEs) or Any Serious Adverse Events (SAEs). A summary of AEs and SAEs considered by the investigator to be drug-related is located in the Reported Adverse Events module. An AE is summarized if the onset date is on or after the first dose of study drug and within 30 days after the last dose, or it occurred before the first dose of study drug and worsened while on the therapy.	Up to 7 weeks
Pharmacokinetics: Maximum Concentration (Cmax) in single dose		Cycle 1(day1-day21)& Cycle 2(day 21-day 49): Predose, 15 minute, 3 hours, 6 hours, 12 hours, 24 hours, 48 hours、day 3, day 4, day 7, day 14 after completion of infusion, Cohort 5 only)
Pharmacokinetics: Cmax in multiple dose		Predose and 15 minutes after completion of Infusion at day 21, day 28, day 42，Predose and 15 minutes, 3 hours, 8 hours, 24 hours, 48 hours, 96 hours after completion of Infusion at day 35，Predose at day 49（the last follow-up）
Pharmacokinetics: Area Under the Concentration-Time Curve (AUC) in single dose		Cycle 1(day1-day 21)& Cycle 2(day 21-day49): up to day 21（blood collection time are as follows ：Predose, 15 minutes, 3 hours, 6 hours, 12 hours, 24 hours, 48 hours, day 3, day 4, day 7, day 14 after completion of infusion, Cohort 5 only)
Pharmacokinetics: AUC in multiple dose		From day 21 up to day 49（blood collection time：Predose and 15 minutes after completion of Infusion at day 21, day 28, day 42，Predose and 15 minutes, 3hours, 8hours, 24hours, 48hours, 96hours after completion of Infusion at day 35，Predose at day 49

Secondary Outcomes

Measure	Description	Time Frame
Adverse Events	Drug-Related Adverse Events (AEs) or Any Serious Adverse Events (SAEs)	4 weeks after disease progression or 4 weeks after the intolerant toxicity occurs or until the subject begins a new tumor treatment (whichever is shorter)
