OGX-011 and Docetaxel in Treating Women With Locally Advanced or Metastatic Breast Cancer

This study has been completed.

Canadian Cancer Trials Group Identifier:
First received: November 22, 2005
Last updated: November 7, 2010
Last verified: March 2010

RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. OGX-011 may help docetaxel kill more tumor cells by making tumor cells more sensitive to the drug.

PURPOSE: This phase II trial is studying how well giving OGX-011 together with docetaxel works in treating women with locally advanced or metastatic breast cancer.

Condition Intervention Phase
Breast Cancer Drug: custirsen sodium Drug: docetaxel Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Study of a Second Generation Clusterin Antisense Oligonucleotide (OGX-011) in Combination With Docetaxel in Advanced Breast Cancer

Further study details as provided by Canadian Cancer Trials Group:

Primary Outcome Measures:
  • Objective response measured by RECIST criteria after accrual of 14 evaluable patients

Secondary Outcome Measures:
  • Toxicity

Estimated Enrollment: 42
Study Start Date: June 2005
Study Completion Date: September 2008
Detailed Description:



  • Determine the efficacy of OGX-011 and docetaxel, in terms of objective tumor response rate, in women with locally advanced or metastatic breast cancer.


  • Determine the tolerability and toxicity of this regimen in these patients.
  • Determine the time to progression and overall survival of patients treated with this regimen.

OUTLINE: This is an open-label, nonrandomized, multicenter study.

Patients receive OGX-011 IV over 2 hours on days -7, -5, -3, 1, 8, and 15 of course 1 and on days 1, 8, and 15 of all subsequent courses. Patients also receive docetaxel IV over 1 hour on days 1 and 8 of all courses. Treatment repeats every 21 days* for up to 10 courses in the absence of disease progression or unacceptable toxicity.

NOTE: *Course 1 is 28 days in length and all subsequent courses (courses 2-10) are 21 days in length.

After completion of study treatment, patients are followed at 4 weeks and then periodically until disease progression.

PROJECTED ACCRUAL: Approximately 42 patients will be accrued for this study.
