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.

Condition or disease Intervention/treatment Phase
Solid Tumors Drug: RC48-ADC Phase 1

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 50 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Study Start Date : November 2015
Estimated Primary Completion Date : May 2020
Estimated Study Completion Date : June 2020

Arm Intervention/treatment
Experimental: RC48-ADC
The phase I component has several dose levels of RC48-ADC (0.5 mg/kg, 1.0mg/kg, 1.5mg/kg, 2.0mg/kg, 2.5mg/kg, 3.0mg/kg, 3.5mg/kg, 4.0 mg/kg and 4.5 mg/kg) and is designed as a traditional dose-escalation study.Determine the recommended Phase II doses and regimens of RC48-ADC. Dosing interval is once two weeks.
Drug: RC48-ADC

Primary Outcome Measures :
  1. maximal tolerance dose (MTD) of RC48-ADC [ Time Frame: DLT will be evaluated on Day 21 during cycle 1 ]
    The dose level in which >= 2 out of 6 patients have dose-limiting toxicity (DLT). The MTD is defined as the previous dose level.

Secondary Outcome Measures :
  1. Safety (the drug safety as assessed by NCI-CTCAE v4.0) [ Time Frame: Up to 1 years ]
    The drug safety as assessed by NCI-CTCAE v4.0
