Abstract

This section provides current contact details and a summary of recent or ongoing clinical trials being coordinated by Cancer International Research Group (CIRG). Clinical trials include:

  1. A multicenter phase III randomized trial comparing docetaxel in combination with doxorubicin and cyclophosphamide (TAC) versus doxorubicin and cyclophosphamide followed by docetaxel (A → CT) as adjuvant treatment of operable breast cancer her2neu-negative patients with positive axillary lymph nodes.CIRG 005

  2. Multicenter phase III randomized trial comparing doxorubicin and cyclophosphamide followed by docetaxel (AC→T) with doxorubicin and cyclophosphamide followed by docetaxel and trastuzumab (AC→TH) and with docetaxel, carboplatin and trastuzumab (TCH) in the adjuvant treatment of node-positive and high-risk node-negative patients with operable breast cancer containing the her2neu alteration. BCIRG 006.

  3. A multicenter phase III randomized trial comparing docetaxel (Taxotere) and trastuzumab (Herceptin) with docetaxel (Taxotere), platinum salt (cisplatin or carboplatin) and trastuzumab (Herceptin) as first line chemotherapy for patients with advanced breast cancer containing the her2neu alteration.

Summary

  • Start date: September 2000
  • Enrollment completed: February 2003
  • Final accrual: 3298 patients

Primary Objective

  • Disease-free survival.

Secondary Objective

  • Overall survival, toxicity and quality of life, pathologic and molecular markers, socioeconomics.

Scheme

Patient Population:

  • Node-positive
  • Adjuvant breast cancer
  • her2neu negative (centrally confirmed by FISH)

Randomization:

Stratify

  • Number of nodes (1–3, 4+)
  • Center

Update

  • The results of the first interim analysis were presented at the San Antonio Breast Cancer Symposium on December 2005, by Dr Eiermann (Poster Session #1069). The safety results were presented and are available on the SABCS and CIRG websites. Additional follow-up is required by the IDMC to evaluate the relative efficacy of combination versus sequential docetaxel-containing chemotherapy in the adjuvant treatment of women with node-positive, her2 breast cancer. Efficacy results will be presented at the final analysis planned Q1, 2008.

Summary

  • Enrollment start date: April 2001
  • Enrollment completed: March 2004
  • Final accrual: 3222 patients
  • Planned interim cardiac analyses after 300, 900 and 1500 patients have received chemotherapy treatment and 6 months follow-up.

Primary Objective

  • Disease-free survival.

Secondary Objective

  • Overall survival, toxicity and quality of life, pathologic and molecular markers, socioeconomics.

Scheme

Patient Population:

  • Node-positive
  • Adjuvant breast
  • High-risk node-negative
  • Her2neu positive (centrally confirmed by FISH in BCIRG laboratories)

Randomization:

Stratify

  • Number of nodes (0, 1–3, 4+)
  • Center

Update

  • The results from the first interim efficacy (at 322 events) and updated safety analyses were presented at the San Antonio Breast Cancer Symposium on December 2005, by Dr D. Slamon (Abstract #1) and are available on the CIRG website. Result of this trial confirms the benefit of Herceptin (H) when combined with docetaxel (AC-TH) or with docetaxel and carboplatin (TCH) without an anthracycline. There are fewer severe cardiac adverse events when H is administered without prior A. Longer follow-up is needed in order to confirm whether non-A-based adjuvant H regimens will have efficacy comparable to A-based regimens. Second interim analysis will present efficacy and safety results.

Summary

  • Enrollment start date: December 2001
  • Enrollment completed: March 2004
  • Final accrual: 263 patients

Based on preclinical synergy seen between docetaxel (T), carboplatin (C) and trastuzumab (H), BCIRG conducted a randomized multicenter phase III trial in women with her2-positive MBC to evaluate the efficacy and safety of H regimens in combination with T or TC.

Primary Objective

  • Time to disease progression.

Secondary Objectives

  • To compare response rate, duration of response, overall survival.
  • To evaluate and compare clinical benefit, defined as CR, PR or stable disease >24 weeks.
  • To compare toxicity between the two arms.
  • To evaluate pathologic and molecular markers for predicting efficacy.
  • To compare peripheral levels of shed her2neu extracellular domain (ECD) with FISH determination in predicting outcome to treatment with Herceptin.

Scheme

Update

  • CIRG randomized 263 patients with her2 FISH + MBC; 131 patients were treated in each arm. Dr Forbes (from the trial ANZ BCTG group) presented results of safety and the TTP analysis conducted after 204 events at ASCO 2006. Additional information presented at ESMO (148PD)
