Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Gentuximab Injection

Arm Description

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.

Outcomes

Primary Outcome Measures

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.
Pharmacokinetics: Maximum Concentration (Cmax) in single dose
Pharmacokinetics: Cmax in multiple dose
Pharmacokinetics: Area Under the Concentration-Time Curve (AUC) in single dose
Pharmacokinetics: AUC in multiple dose

Secondary Outcome Measures

Adverse Events
Drug-Related Adverse Events (AEs) or Any Serious Adverse Events (SAEs)
Anti-drug antibody:Number of Participants With Anti-drug Antibodies
A sample will be considered positive for circulating anti-drug antibodies if it exhibits a post-baseline antibody level that exceeds the upper 95% confidence interval of the mean determined from the normal anti-drug level seen in healthy untreated individuals. A participant will be considered to have an anti-drug response if there are 2 consecutive positive samples or if the final sample tested is positive.
Objective response rate: Number of Participants With Objective Response (ORR)
Participants achieved disease control if they had a BOR of CR, PR or SD. Progressive Disease (PD) and those participants which were Not Evaluable (NE) were also reported. According to RECIST v1.1, CR was the disappearance of all non-nodal target lesions, with the short axes of any target lymph node reduced to <10 mm, the disappearance of all nontarget lesions, and the normalization of tumor marker levels (if tumor markers were initially above the upper limit of normal); PR was defined as at least a 30% decrease in the sum of the diameters of target lesions (including the short axes of any target lymph node), taking as reference the baseline sum diameter. SD was neither sufficient shrinkage to qualify as PR nor sufficient increase to qualify as PD, taking as reference the smallest sum diameter since treatment started.
Progression-free survival (PFS)
Defined as the time from randomization to the patient tumor progression or death.

5. Study Description

Brief Summary
The primary objective is to evaluate the safety and, tolerabilitytolerance, pharmacokinetices and immunogenicity of escalating single doses and subsequent multiple dose of Gentuximab Injection in patients with late recurrence of metastatic solid tumors and to determine the maximum tolerated dose（MTD） and dose limiting toxicities（DLT）.with single and subsequent multiple intravenous infusion in patients with late recurrence of metastatic solid tumors and to provide a basis for the protocol design of later clinical trials. The secondary objective is to evaluate the pharmacokinetics, pharmacodynamics and immunogenicity, and tumor response of multiple dose of Gentuximab Injection in patients with late recurrence of metastatic solid tumors.
Detailed Description
The safety profile of Gentuximab Injection will be explored together with the pharmacokinetics, pharmacodynamics and tumour response to treatment with Gentuximab Injection to recommend the dosing regimen for further clinical studies. The pharmacokinetic properties of Gentuximab Injection will be evaluated after single and multiple dose administrations at different dose levels.
