Title

ICE – Study: Ibandronate with or without capecitabine in elderly patients with early breast cancer. BIG 4-04 / GBG 32. (see also description under GBG)

Coordinator(s)

Summary

Primary Objective

• To compare the event-free survival in elderly patients after local treatment for primary breast cancer treated with either ibandronate alone or ibandronate and capecitabine as adjuvant treatment.

Secondary Objectives

• To compare the overall survival between the two Arms.
• To determine the compliance in both Arms.
• To determine the toxicity in both Arms.
• To determine the rate of bone-related events in hormonsensitive and insensitive disease (with or without anastrozol).
• To determine the preference to oral or intravenous application of ibandronate.
• To assess quality of life.

Tertiary Objective

• To determine prognostic factors on tumor tissue collected from primary surgery and to correlate them with study treatment effect.

Scheme

Update

• Planned accrual: 1394 patients.
