Study Description

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 lyposomal 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 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 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.

   Sudden death (defined as within 24 hours; unexplained); Heart failure NYHA criteria class III-IV and LVEF decline defined as an absolute drop ≥10% resulting in a final LVEF <50%
6. Level II cardiotoxicities [ Time Frame: Baseline up to 18 weeks after patient entry ]
   Absolute drop ≥10% resulting in a final LVEF <50% and asymptomatic or heart failure NYHA criteria class II
7. Polymorphism of HER2 gene (SNP) [ Time Frame: Baseline ]
