A Study of Neratinib Plus Capecitabine Versus Lapatinib Plus Capecitabine in Patients With HER2+ Metastatic Breast Cancer Who Have Received Two or More Prior HER2 Directed Regimens in the Metastatic Setting

Official Title

A Study of Neratinib Plus Capecitabine Versus Lapatinib Plus Capecitabine in Patients With HER2+ Metastatic Breast Cancer Who Have Received Two or More Prior HER2 Directed Regimens in the Metastatic Setting

Summary:

This is a randomized, multi-centre, multinational, open-label, active-controlled, parallel design study of the combination of neratinib plus capecitabine versus the combination of lapatinib plus capecitabine in HER2+ MBC patients who have received two or more prior HER2 directed regimens in the metastatic setting.

Trial Description

Primary Outcome:

  • Independently assessed Progression Free Survival
  • Overall Survival
Secondary Outcome:
  • Investigator Assessed Progression Free Survival
  • Objective Response Rate (ORR)
  • Clinical Benefit Rate (CBR)
  • Duration of Response (DOR)
  • Time to intervention for symptomatic metastatic central nervous system disease
  • Safety (Adverse Events [AEs] and Serious Adverse Events [SAEs])
  • Health Outcomes Assessments
This is a randomized, multi-centre, multinational, open-label, active-controlled, parallel design study of the combination of neratinib plus capecitabine versus the combination of lapatinib plus capecitabine in HER2+ MBC patients who have received two or more prior HER2 directed regimens in the metastatic setting. Patients will be randomized in a 1:1 ratio to one of the following treatment arms:
  • Arm A: neratinib (240 mg once daily) + capecitabine (1500 mg/m^2 daily, 750 mg/m^2 twice daily [BID])
  • Arm B: lapatinib (1250 mg once daily) + capecitabine (2000 mg/m^2 daily, 1000 mg/m^2 BID) Patients will receive either neratinib plus capecitabine combination or lapatinib plus capecitabine combination until the occurrence of death, disease progression, unacceptable toxicity, or other specified withdrawal criterion.
