About this study

Official title: Impact of Chemotherapy Followed by Aromatase Inhibitors on Bone Health of Women With ER-positive Early Breast Cancer in Real World Clinical Settings in Greece

The purpose of this study is to identify the combined impact on bone loss as well as the incidence of bone fractures in women with estrogen receptor (ER)-positive, early breast cancer treated with an aromatase inhibitor (AI) either as first line therapy or as maintenance therapy after initial treatment with chemotherapy, in real life clinical settings in Greece.

Read the detailed description

Subjects with ER-positive early breast cancer will be treated with AIs either as first line therapy or as maintenance therapy after initial treatment with chemotherapy. The total study duration will be 24 months comprising of a recruitment period of 12 months and a follow-up period of 12 months for each participating subject. The primary outcome variable is the mean percentage variation in lumbar spine (LS) bone mineral density (BMD) during the 12 month follow - up period. Measurements will be taken before and after chemotherapy and at the end of the 12 month follow - up period.

AIs as first line therapyPatients in postmenopausal status, with ER-positive early breast cancer, treated with an AI as first line therapy for 12 months.
Receives: Drug: Aromatase Inhibitors
AIs after chemotherapyPatients in postmenopausal status, with ER-positive early breast cancer, treated with an AI as maintenance therapy for 12 months after initial treatment with anthracycline- and/or taxane-based chemotherapy (chemotherapy treatment duration: 1-6 months).
Receives: Drug: Aromatase Inhibitors; Drug: Chemotherapy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Percentage Change in Lumbar Spine Bone Mineral Density From Baseline (Before Chemotherapy Commencement) to Month 12 of AI Therapy

    BMD was evaluated at lumbar spine (LS) and hip (HIP) with measurements taken before CT, before AI therapy and at the end of the 12 month followup period while on AI treatment. Dual Energy X-Ray Absorptiometry (DEXA scan) was used with all measurements performed with the Explorer absorptiometer produced by Hologic, Bedford, MA, USA in the same referral site in Athens, apart from two centres in other cities which used however the same absorptiometer model with identical software.

    The primary outcome variable was the mean percentage change in LS BMD between the pre CT treatment measurement and the post 12 months AI measurements in the CT cohort. The HT cohort was included as a control group.

    Measured: Baseline and month 13-18 (1-6 months of chemotherapy + 12 months of AI therapy)

Secondary outcomes (6)
  1. Percentage Change in Total Hip Bone Mineral Density From Baseline to Month 12 of AI Therapy.

    Measured: Baseline and month 13-18 (1-6 months of chemotherapy + 12 months of AI therapy)

  2. Percentage Change in Lumbar Spine Bone Mineral Density Before AI Commencement to Month 12 of Therapy for Patients Who Are Treated With AIs as First Line Therapy

    Measured: From AI commencement to month 12 of AI therapy

  3. Percentage Change in Total Hip Bone Mineral Density Before AI Commencement to Month 12 of Therapy for Patients Who Are Treated With AIs as First Line Therapy

    Measured: From AI commencement to month 12 of AI therapy

  4. Bone Fracture Rate

    Measured: During the 12 months of AI Therapy

  5. Mean Percentage Change in Lumbar Spine Bone Mineral Density From Baseline (Before Chemotherapy Commencement) to Chemotherapy Completion

    Measured: Baseline and month 1-6 (depending on duration of chemotherapy)

  6. Mean Percentage Change in Lumbar Spine Bone Mineral Density From AI Commencement to Month 12 of Therapy.

    Measured: Month 1-6 (depending on duration of chemotherapy) and month 13-18

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Other Disorders of Bone Density and Structure, run by Hellenic Breast Surgeons Society at 1 site in Greece.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Sep 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Percentage Change in Lumbar Spine Bone Mineral Density From Baseline (Before Chemotherapy Commencement) to Month 12 of AI Therapy (time frame: Baseline and month 13-18 (1-6 months of chemotherapy + 12 months of AI therapy)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01298362, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Sep 2016.
