NCT ID: NCT02236000

Last Updated: 2023-01-26

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 49 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2014-08-31
• Study Completion Date: 2021-08-31

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.

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 was 27 patients. The sample size of the Phase II portion will be 22 evaluable patients (and 4 replacement patients). The total study enrollment, phase Ib and II, will be a maximum of 50 patients.

Submission of diagnostic tumor samples and blood samples for FB-10 correlative science studies will be a study requirement for all patients. Blood samples for pharmacokinetics (PKs) and for future study will be collected prior to administration of study therapy on Cycle 1/Day 1, Cycle 1/Day 8, and Cycle 2/Day1.

A tumor biopsy will be procured from an accessible site of metastasis before study therapy is initiated (after the patient has signed the consent and has been screened for eligibility).

Eligibility Criteria

Inclusion Criteria

• The ECOG performance status must be less than or equal to 2.
• Patients must have the ability to swallow oral medication.
• Patients must have histologic or cytologic confirmation of the diagnosis of invasive adenocarcinoma of the breast.
• Patients must have had anti-HER2 based therapy with pertuzumab and trastuzumab for neoadjuvant therapy, adjuvant therapy or with first line therapy for metastatic disease (which may include trastuzumab and pertuzumab either sequentially or in combination).
• There must be documentation that the patient has evidence of measurable metastatic breast cancer that is accessible to biopsy at study entry.
• Patients must have estrogen receptor (ER) analysis performed prior to study entry. If ER analysis is negative, then progesterone receptor (PgR) analysis must also be performed. (Patients are eligible with either hormone receptor-positive or hormone receptor-negative tumors.)

• Total bilirubin must be less than or equal to 1.5 x upper limit of normal (ULN), and
• aspartate aminotransferase (AST) and alanine aminotransferase (ALT) must be less than or equal to 1.5 x ULN for the lab or less than or equal to 5 x ULN if liver metastasis.
• Serum creatinine performed within 4 weeks prior to study entry must be less than or equal to 1.5 x ULN for the lab.
