Brief Summary:
This open-label study assessed the safety, tolerability and pharmacokinetics of ALT-P7(HM2-Drug Conjugate) in patients with HER2-positive metastatic breast cancer who have progressed on previous Trastuzumab-based therapy. Patients received ALT-P7(0.3 mg/kg~5.4 mg/kg, 7 groups) intravenously on Day 1 of each 3-week cycle.

Arm Intervention/treatment
Experimental: ALT-P7
  • 8 groups: 0.3 mg/kg, 0.6 mg/kg, 1.2 mg/kg, 2.4 mg/kg, 3.6 mg/kg, 4.2 mg/kg, 4.5 mg/kg, 4.8 mg/kg,
  • Administration: Day 1 of each 3-week cycle
Biological: ALT-P7 (HM2-MMAE)
Antibody-Drug Conjugate




Primary Outcome Measures :
  1. DLT test [ Time Frame: 21 days after first administration ]
    Determination of Maximum Tolerated Dose(MTD) and the dose level showing Dose Limiting Toxicity(DLT), or determination of Recommended Phase II Dose(RP2D) as an alternative to MTD establishment


Secondary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [ Time Frame: up to 4 weeks ]
    Evaluate adverse events by the Common Terminology Criteria for Adverse Event (CTCAE v4.03) classification, immune-related adverse events(irAEs)

  2. Pharmacokinetics test [ Time Frame: up to 4 weeks ]
    analyze metabolism and discover the fate of a ALT-P7 from administration up to completely eliminated from the body (Group 3(1.2 mg/kg) ~ Group 7(5.4 mg/kg))

  3. Immunogenicity test [ Time Frame: up to 4 weeks ]
    After administration of the drug for clinical trial, the descriptive statistics of the dose group and the measurement point are calculated

  4. Efficacy test [ Time Frame: At the end of Cycle 2 (each cycle is 21 days) ]
    Provide descriptive statistics for each capacity group(the number of subjects, average, standard deviation, median, minimum value, maximum value)
