Study information
Scientific title
The role of ZOLedronic acid and MENOpausal status on the tumour and bone microenvironment in patients with early breast cancer: a single centre, randomised, proof of concept clinical study
Acronym
The ZOLMENO study
Study hypothesis
The aim of this study is to identify the mechanisms responsible for the differential effect of zoledronic acid seen in pre- and post-menopausal women with early breast cancer. This study has arisen directly from the AZURE trial which was the first to demonstrate that menopausal status is a significant modifier of the effects of zoledronic acid (ZOL) in early breast cancer in that women who were post-menopausal significantly benefitted from adjuvant ZOL (with prevention of one death in every six), whereas this effect was not seen in pre-menopausal women. It is hypothesised that this differential effect may be linked to differential levels of follistatin and activin in pre- and post-menopausal women.

Intervention
Participants in both arms receive a single intravenous infusion of zoledronic acid 4mg in 100ml 0.9% sodium chloride over 15 minutes on either day seven pre-surgery or day 21 post-surgery. The purpose of the randomisation is to allow the effect of zoledronic acid to be separated from the effect of surgery and to permit both pre-administration and post administration bone marrow biopsies to be collected whilst the participants are under anaesthetic during surgery. Participants are randomised by the Informatics Team at the Cancer Clinical Trials Office at Weston Park Hospital using a computer generated randomisation schedule which includes age group stratification: 40-54 years and ≥55 years.

Primary outcome measures
Change in serum follistatin measured by ELISA using validated lab kits at day 28 post-ZOL administration.
Secondary outcome measures
The following secondary outcome measures, all compared relative to menopausal status (pre- vs. post-menopausal) and timing of ZOL administration (Group A vs. Group B), includes:
1. Change in serum follistatin measured by ELISA using validated lab kits at day 7 and 28 post-ZOL infusion
2. Change in serum activin measured by ELISA using validated lab kits at day 7 and day 28 post-ZOL infusion
3. Change in serum follistatin measured by ELISA using validated lab kits from day 0 (surgery) to day 21 and day 28 post-surgery
4. Change in serum activin measured by ELISA using validated lab kits from day 0 (surgery) to day 21 and day 28 post-surgery
5. Follistatin and activin levels measured by ELISA using validated lab kits in tumour samples obtained at surgery

Participant exclusion criteria
1. Any previous diagnosis or treatment of cancer that could confound results and endpoints (allowed situations include non-melanomatous skin cancer or superficial bladder cancer)
2. Patients with an estimated life expectancy of <6 months
3. Any diagnosis of a bone marrow disorder
4. Any previous bisphosphonate treatment
5. Use of hormone replacement therapy (HRT) in the past 30 days or a diagnosis of hormonal imbalance such as polycystic ovarian syndrome
6. Current active dental problems including dental abscess or infection of the jawbone (maxilla or mandible), any open oral wounds or a current or previous diagnosis of osteonecrosis of the jaw
7. Recent (within 4 weeks) or planned dental or jaw surgery (recent dental fillings, scaling, polishing or minor gingival surgery do not exclude the patient)
8. Any other serious medical or psychiatric condition which in the opinion of the investigator could affect participation in the ZOLMENO study, including dehydration, notable electrolyte disturbances, significant use of nephrotoxic, antiangiogenic or hypocalcaemia inducing drugs or history of significant renal failure, which in the opinion of the screening investigator, would render the patient unsuitable for zoledronic acid or sample collection
