Brief summary
The aim of this prospective, randomized, multicenter, open-label, explorative phase II study is to identify the impact of (neo)adjuvant denosumab on the systemic immunity and local immunologic microenvironment in postmenopausal patients with HER2 negative non-metastatic primary breast cancer.
Detailed description
In this study, postmenopausal patients with stage T1c + grade 3, stage II or III, HER2-negative breast cancer, which are planned to undergo surgery followed by adjuvant AC-T chemotherapy, are randomized between no denosumab, denosumab low dosing and denosumab high dosing. Denosumab administration will start one week before surgery and continue until the last chemotherapy cycle.

Inclusion criteria
* Postmenopausal, defined as 1 year without menstrual activity, previous bilateral oophorectomy, age older than 60 years or baseline FSH \>20 U/l and estradiol \<110 pmol/l. * Clinical stage T1c + grade 3, stage II or III breast cancer amenable to adjuvant AC-T combination chemotherapy. * Measurable disease (breast and/or lymph nodes). * Histological proven HER2-negative breast cancer in the core biopsy material. * WHO 0-2. * Adequate bone marrow function (within 4 weeks prior to randomization): WBC≥3.0x109/l, neutrophils ≥1.5 x 109/l, platelets ≥100 x 109/l. * Adequate liver function (within 4 weeks prior to randomization): bilirubin ≤1.5 X upper limit of normal (UNL) range, ALAT and/or ASAT ≤2.5 x UNL, Alkaline Phosphatase ≤5 x UNL. * Adequate renal function (within 4 weeks prior to randomization): the calculated creatinine clearance should be ≥50 ml/min. * Albumin-adjusted serum calcium \> 2.0 mmol/L (8.0mg/dL) * Accessible for treatment and follow-up. * Written informed consent.
Exclusion criteria
* Evidence of distant metastases (M1). * History of breast cancer. * Prior chemotherapy or radiation therapy. * Previous malignancy within 5 years, with exception of a history of a previous basal cell carcinoma of the skin or pre-invasive carcinoma of the cervix. * Prior or current bisphosphonate or denosumab usage. * Serious other diseases as recent (last 6 months) myocardial infarction, clinical signs of cardiac failure or clinically significant arrhythmias. * Current active dental problems including dental abscess or infection of the jawbone (maxilla or mandible), non-healed dental or oral surgery, a current or prior diagnosis of osteonecrosis of the jaw or planned invasive dental procedures for the course of the study. * Known hypersensitivity reaction to any of the components of the treatment. * Medical or psychological condition which in the opinion of the investigator would not permit the patient to complete the study or sign meaningful informed consent.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in intratumoral T-cell (CD4, CD8 and Treg) numbers and function between the baseline biopsy and the surgical specimen. | The change can be determined after the surgical specimen is obtained, which is around two weeks after enrolment. | The change will be determined by use of IHC and immunofluorescent stainings. |
| Change in myeloid cell (M1/M2 Macrophage, MDSC, DC) numbers and function between the baseline biopsy and the surgical specimen. | The change can be determined after the surgical specimen is obtained, which is around two weeks after enrolment. | The change will be determined by use of IHC and immunofluorescent stainings. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in functional response of T-cells. | Measurements will be done in PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Changes will be determined by comparing PBMCs (using stimulation tests) before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration. |
| Change in mature and immature myeloid cells (M1/M2 macrophage, MDSC, DC). | Measurements will be done in PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Shifts will be determined by comparing PBMCs (using flow cytometry) before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration. |
| Shift in myeloid cell function. | Measurements will be done in PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Shifts will be determined by comparing PBMCs (using triggering tests) before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration. |
| Change in stimulation capacity APCs. | Measurements will be done in PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Changes will be determined by comparing PBMCs (using restimulation tests) before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration. |
| Change in serum levels of RANKL and OPG. | Measurements will be done in serum from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Changes will be determined by comparing serum before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration, using ELISA. |
| Shift in activated T effector cell levels. | Measurements will be done in PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Shifts will be determined by comparing PBMCs (using flow cytometry) before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration. |
| Correlation of tumor measurements with serum measurements. | Measurements will be done in tumor material and serum from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment and tumor material from baseline and surgery. | Measurements in tumor and serum will be correlated. |
| Correlation of tumor measurements with PBMCs measurements. | Measurements will be done in tumor material and PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment and tumor material from baseline and surgery. | Measurements in tumor and PBMCs will be correlated. |
| Correlation of serum measurements and PBMCs measurements. | Measurements will be done in PBMCs/serum from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment and tumor material from baseline and surgery. | Measurements in serum and PBMCs will be correlated. |
| Toxicity according to NCI CTCAE v4.03. | Toxicity will be assessed from start treatment up to 30 days following the last dose of treatment. | Toxicities are graded according to NCI CTCAE v4.03. |
| Difference in descriptive event free survival (EFS) at 3 years based on immune response. | EFS will be determined after 3 years. | After 3 years of follow up, differences in EFS based on immune response will be determined. |
| Change in serum cytokine levels (TNF-alpha, interleukines, IFN gamma). | Measurements will be done in serum from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Changes will be determined by comparing serum before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration, using luminex. |
| Shift in regulatory T-cell levels. | Measurements will be done in PBMCs from before start treatment, day of surgery and 7 days after last chemotherapy administration, which will be around 8 months after enrolment. | Shifts will be determined by comparing PBMCs (using flow cytometry) before start treatment, at day of surgery before surgery and 7 days after last chemotherapy administration. |
