Brief Summary:

This study is being done for the following reasons:

  • The study has two parts. The purpose of the first part (Phase I) of the study is to find out the highest dose of neratinib that can be given safely with T-DM1.
  • The purpose of the second part of the study (Phase II) is to find out whether the dose of neratinib with T-DM1 determined in Phase I will keep breast cancer from getting worse for a period of time.
  • In order to learn more about study therapy levels in blood and discover genetic and protein changes associated with cancer, the study includes special research tests using samples from blood and from breast tumor. Blood samples will be collected before study treatment, once during treatment, and after study treatment stops.
  • In the optional part of this study, three biopsies will be performed to obtain fresh tumor samples from an area where your cancer has spread.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Neratinib Drug: T-DM1 Phase 1 Phase 2

Detailed Description:

The FB-10 study is designed as an open label, single arm, Phase Ib/II study with a dose-escalation phase and an expanded cohort (phase II) to evaluate the combination of trastuzumab emtansine (T-DM1) with neratinib in women with metastatic, HER2-positive breast cancer. The primary aim of the phase Ib portion of this study is to determine the safety and tolerability of the two-drug combination. The primary aim of the phase II portion is to demonstrate efficacy.

Patients will receive concurrent therapy with T-DM1 (3.6 mg/kg IV) on Day 1 of a 3-week (21 day) cycle and neratinib as a continuous daily oral dose. The neratinib dose-escalation will include 4 dose levels (120 mg, 160 mg, 200 mg, and 240 mg). At the recommended phase II dose (RP2D) of the T-DM1 and neratinib combination, up to 39 additional patients will be treated.

The sample size of the phase I portion of the study will be between 2 and 24 patients. The sample size of the Phase II portion will be 42 patients. Approximately 6 patients at the Phase I RP2D level will be included in the Phase II portion. The total study enrollment will be a maximum of 63 patients. Accrual is expected to occur over 16 months.

Submission of diagnostic tumor samples and blood samples for FB-10 correlative science studies will be a study requirement for all patients. Blood samples will be collected at baseline, at Cycle 2, Day 1, and at progression. Blood samples for pharmacokinetic (PK) determination will be collected at Phase 1 sites from consenting patients at various time points during the first 24 hours of study therapy (Cycle 1, Days 1 and 2).

An optional tumor biopsy will be procured from consenting patients from an accessible site of metastasis before study dose level assignment (after the patient has signed the consent form and has been screened for eligibility), after Cycle 1 of treatment, and at the time of disease progression.

Arm Intervention/treatment
Experimental: Neratinib and T-DM1 Drug: Neratinib

Dose-Escalation Phase (Part 1) - Neratinib Dose-escalation will proceed on the basis of DLT during Cycle 1 starting at 120 mg/day.

Dose level 1: 120 mg/day; Dose level 2: 160 mg/day; Dose level 3: 200 mg/day; Dose level 4: 240 mg/day

Dose-evaluation Phase (Part 2) - Patients will receive the highest dose of neratinib with T-DM1 found in Phase I as study therapy


Drug: T-DM1

Dose-Escalation Phase (Part 1) - Trastuzumab emtansine (T-DM1) will be given at 3.6 mg/kg IV Day 1 every 21 days.

Dose-evaluation Phase (Part 2) - Trastuzumab emtansine (T-DM1) will be given at 3.6 mg/kg IV Day 1 every 21 days.





Primary Outcome Measures :
  1. Safety and tolerability of T-DM1 and neratinib to determine the recommended Phase II dose (RP2D) [ Time Frame: Day 1, 8, and 15 of cycle 1. ]
    If 1 of 3 patients in this cohort experiences a dose limiting toxicity (DLT), 3 more patients will be added at the same dose level. If 0 of 3 initial patients or 1 of 6 patients in an expanded cohort experiences a DLT, the dose for the next cohort will be escalated to dose level 2; otherwise, the combination will be considered too toxic.

  2. Overall response rate (ORR) by measurement of target lesions [ Time Frame: Every 42 days after the start of protocol therapy through disease progression, approximately 2 years ]

Secondary Outcome Measures :
  1. Progression-free survival (PFS) time from start of study therapy to disease progression [ Time Frame: From the start of study therapy through 30 days after study therapy stops, approximately 2 years ]
  2. Objective tumor decrease and stable disease (SD) measurement of target lesions [ Time Frame: Measurement of target lesions prior to study therapy and every 42 days through the end of study therapy, approximately 2 years. ]
  3. Adverse events experienced by participants as a measure of toxicity [ Time Frame: Day 1 of every cycle; at the end of protocol therapy; and 30 days following the end of protocol therapy in addition day 8 and 15 of cycle one. ]
  4. Molecular and genetic profiles of tumor samples collected. [ Time Frame: Baseline (prior to study entry), within 72 hours prior to day 1 of cycle 2, and at the time of disease progression, approximately 2 years ]
  5. Pharmacokinetic interactions [ Time Frame: Before therapy begins, within 72 hours prior to day 1 of cycle 2, and at the time of disease progression, approximately 2 years ]
    Describe pharmacokinetic variations in absorption, metabolism and elimination that may affect total drug concentration.

  6. Therapeutic drug monitoring (TDM) [ Time Frame: Before therapy begins, within 72 hours prior to day 1 of cycle 2, and at the time of disease progression, approximately 2 years ]
    TDM analysis measures the plasma concentrations of a therapeutic agent and metabolites in patients to individualize appropriate drug dosages and schedules.
