Brief Summary:

The primary goal is to determine the maximum tolerated dose (MTD) of the combination of T-DM1 and non-pegylated liposomal doxorubicin in metastatic breast cancer (mBC) patients previously treated with taxanes and trastuzumab-based therapy.

In addition, pharmacokinetic data on the combination of T-DM1 and liposomal doxorubicin will be obtained.


Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Trastuzumab and non-pegylated liposomal doxorubicin Phase 1

Detailed Description:

Subjects: Age ≥ 18 years with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer that have relapsed or progressed on or after taxanes and trastuzumab-based therapy. Subjects must have histologic or cytologic confirmation of the HER2-positive metastatic breast cancer. Evidence of measurable or evaluable metastatic disease is required.

Primary objective:

  • To determine the maximum tolerated dose (MTD) of the combination of T-DM1 and non-pegylated liposomal doxorubicin in metastatic breast cancer (mBC) patients previously treated with taxanes and trastuzumab-based therapy.

Secondary objectives:

  • To determine the efficacy of the combination of T-DM1 and non-pegylated liposomal doxorubicin, defined by the overall response rate (ORR), clinical benefit rate (CBR), number of progressions and number and reasons for deaths.
  • To assess the safety profile of the combination of T-DM1 and non-pegylated liposomal doxorubicin, defined by all toxicities reported during the study.
  • To evaluate the cardiac safety of the combination of T-DM1 and non-pegylated liposomal doxorubicin measured by left ventricular ejection fraction (LVEF) as assessed by echocardiography, cardiac troponin I and B-type natriuretic peptide (BNP) levels.
  • To evaluate the potential role of single nucleotide polymorphisms (SNP) in the predisposition for developing cardiotoxicity.
  • To analyze the pharmacokinetics (PK) profile of T-DM1 and its metabolites and non-pegylated liposomal doxorubicin.

Type of study: This is a prospective dose-finding, multicenter and open-label phase I clinical trial.

Treatment: Trastuzumab emtansine (T-DM1) will be administered at a fixed dose of 3.6 mg/kg IV on Day 1 every 3 weeks and three cohorts of patients with three different dose levels of conventional non-pegylated liposomal doxorubicin (45 mg/m2, 50 mg/m2 and 60 mg/m2) IV on Day 1 in cycles of 21 days each are planned.
