Brief Summary

A tolerance, safety and pharmacokinetic ascending dose phase I Study of RC48-ADC administered intravenously to subjects with HER2-positive malignant in advanced malignant solid tumors.

Conditions

Solid Tumors

Outcome Measures

Primary Outcomes (1)

• Maximal Tolerance Dose (MTD) of RC48-ADC

  The dose level in which \>= 2 out of 6 patients have dose-limiting toxicity (DLT). The MTD is defined as the previous dose level.

  DLT will be evaluated on Day 28 during cycle 1

Secondary Outcomes (1)

• Safety (the drug safety as assessed by NCI-CTCAE v4.0)

  up to 2 years

Study Arms (1)

RC48-ADC

EXPERIMENTAL

The phase I component has several dose levels of RC48-ADC (0.1mg/kg，0.5 mg/kg, 1.0mg/kg, 1.5mg/kg, 2.0mg/kg, 2.5mg/kg, 3.0mg/kg, 3.5mg/kg and 4.0 mg/kg) and is designed as a traditional dose-escalation study.Dosing interval is once two weeks.

Drug: RC48-ADC
