Outcome Measures

Primary Outcomes (2)

  • Adverse events

    Adverse events will be evaluated according to the NCI Common Terminology Criteria for Adverse Events (CTCAE, V5.0), which includes spontaneously reported adverse events as well as clinically significant changes in vital signs, physical examination, laboratory tests, electrocardiogram, and other examinations conducted during the trial.

    Up to 30 days

  • DLT

    DLT is defined as the occurrence of any of the following adverse events defined by NCI CTCAE V5.0 after drug administration: 1) grade 3 (severe) toxicity related to the investigational drug, such as events resulting in hospitalization or leading to serious or permanent disability or defect; 2) grade 4 (life-threatening) toxicity or any toxicity deemed by the investigator to be significantly severe; 3) grade 3 neutropenia accompanied by infection or fever of ≥38.5℃

    up to 1 weeks

Secondary Outcomes (9)

  • Pharmacokinetic parameters,Tmax

    Evaluated at baseline, during drug infusion, and within 24 hours after drug administration

  • Pharmacokinetic parameters, Cmax

    Evaluated at baseline, during drug infusion, and within 24 hours after drug administration

  • Pharmacokinetic parameters, λz

    Evaluated at baseline, during drug infusion, and within 24 hours after drug administration

  • Pharmacokinetic parameters, t1/2

    Evaluated at baseline, during drug infusion, and within 24 hours after drug administration

  • Pharmacodynamic parameters, blood cadmium

    Evaluated at baseline, during drug infusion, and within 24 hours after drug administration

  • +4 more secondary outcomes

Study Arms (2)

GMDTC for injection

EXPERIMENTAL

The subjects assigned to the treatment group will receive once medication at 8:00 am on the second day after admission.

Drug: GMDTC for injection

Normal saline group

PLACEBO COMPARATOR

The subjects assigned to the placebo group will receive once medication at 8:00 am on the second day after admission.

Other: Normal saline

Interventions

GMDTC for injection with a specification of 0.5g/vial, 250mg,500mg,850mg,1200mg,1600mg,2000mg, and administered by intravenous infusion. Using 0.9% physiological saline (0.5g will be prepared with 250mL injection solution to achieve a concentration of 2mg/mL). Using an infusion pump at a rate of 4mL/min according to the dosage, and any infusion reactions will be recorded. The injection solution for both the experimental and placebo groups should be prepared by a non-blind investigator independent of the trial.

GMDTC for injection

0.9% physiological saline for injection with a specification of 250ml/bag, and administered by intravenous infusion. Using an infusion pump at a rate of 4mL/min according to the dosage, and any infusion reactions will be recorded. The injection solution for both the experimental and placebo groups should be prepared by a non-blind investigator independent of the trial.

Masking Details
This clinical study is a double-blind study, in which participants such as clinical researchers, project managers, and project monitors are unaware of the random coding and drug administration groups of the subjects. Non-blind monitoring during the clinical study will be conducted by non-blind monitors. In addition, drug preparation will be carried out by non-blind researchers independent of this study. Analysis and testing personnel will also adopt blind analysis.
