Evaluation of Trastuzumab In Patients With HER2 Positive Persistent Or Recurrent Vulvar Paget's Disease


Paget's Disease of the Vulva

Trial Phase

Phase 2

Trial Purpose and Description

Trial Purpose

This is a phase II open-label study of the activity and safety of trastuzumab in patients with vulvar Paget's disease with overexpression of HER2 on biopsy.

Trial Description

The primary objective will be to estimate the anti-tumor activity of trastuzumab by evaluating the response to trastuzumab therapy in patients with recurrent or persistent vulvar Paget's disease demonstrating HER2/neu overexpression by immunohistochemistry and/ or FISH ((fluorescence in situ hybridization).

The secondary objectives:

  • To evaluate the quality of life, based on the severity of the patients' vulvar itching on a 4-point verbal rating scale from 0 to 3 (0=no itching, 1=mild itching/ bothersome, 2=moderate itching/ troublesome, 3=severe itching/ extremely troublesome) as well as on the severity of the patients' vulvar pain on a numeric pain scale from 0-10 (0=no pain, 1-3=mild pain, 4-6=moderate pain, 7-10=severe pain).
  • To assess the frequency and severity of observed adverse effects
  • To assess the frequency/ incidence of HER2 in Paget's disease of the vulva
