Brief Summary

Breast cancer is rarely curable after metastasis, and the therapeutic options are limited. Interestingly, the host immune response is strongly predictive for the effect of chemotherapy in subgroups of patients with breast cancer. The aim is to release the brake on the immune response by use of ipilimumab, which blocks CTLA-4 and may deplete regulatory T cells, combined with nivolumab (anti PD1). Importantly, it is possible that non-responders to nivolumab/ipilimumab (nivo/ipi) can be turned responders by use of immunogenic chemotherapy.

Detailed Description

There is compelling evidence from animal studies, supported by data from humans, that some chemotherapeutic agents are immunogenic. Doxorubicin and cyclophosphamide have been shown to be particularly powerful inducers of immunogenic cell death. Both agents fulfil 5/5 criteria established for assessing the immunogenicity of different chemotherapeutic drugs. There is also strong evidence from humans, particularly in breast cancer, indicating that the clinical effect of doxorubicin and cyclophosphamide depends on the host immune response. Further, these agents have been shown to induce a Type I interferon immune response in breast cancer. Taken together, there is a strong rationale for synergy between doxorubicin/cyclophosphamide and PD-1/CTLA-4 blockade. The trial combines nivolumab and ipilimumab with established 1st choice chemotherapy in patients with metastatic hormone reseptor positive breast cancer. Nivolumab/ipilimumab (nivo/ipi) may i) potentiate the patient´s spontaneous anti-tumor immune response ii) synergize with chemotherapeutic agents that induce immunological cell death

Ipilimumab

Intervention Type: DRUG

Eligibility Criteria

Inclusion Criteria

2. Adequate core or excisional study biopsy of a tumor lesion. Lesions in previously irradiated areas may only be used for the biopsy if the lesion has appared or progressed after radiation. No anti-tumor treatment is allowed between the time point for biopsy and study entry.

3. Measurable metastatic disease according to RECIST

4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

5. Signed Informed Consent Form

6. Women or men aged ≥ 18 years

7. A minimum of 12 months from adjuvant/neoadjuvant chemotherapy with antracyclins to relapse disease

8. A maximum of one previous line with chemotherapy in the metastatic setting

9. Chemotherapy is considered as preferred treatment

10. Previous endocrine and targeted therapy is allowed

11. No use of systemic corticosteroids at study entry

12. Female subject of childbearing potential should have a negative urine or serum pregnancy within 7 days prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

13. Female subjects of childbearing potential should agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of < 1% per year, during the treatment period and for at least 5 months after the last dose of study therapy.

14. Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 7 months after the last dose of study therapy

15. Able to swallow and retain orally administered medication

16. Adequate organ function as defined in Table 1

Exclusion Criteria

1. Malignancies other than breast cancer within 5 years prior to randomization, with the exception of those with a negligible risk of metastasis or death and treated with expected curative outcome (such as adequately treated carcinoma in situ of the cervix or basal or squamous cell skin cancer)

2. Spinal cord compression not definitively treated with surgery and/or radiation, or previously diagnosed and treated spinal cord compression without evidence that disease has been clinically stable for > 8 weeks prior to randomization

3. Known CNS disease, except for asymptomatic CNS metastases, provided all of the following criteria are met:

1. Measurable disease outside the CNS

2. Asymptomatic for CNS disease > 4 weeks

3. No ongoing requirement for corticosteroids as therapy for CNS disease

4. No radiation of brain lesions within 2 weeks prior to randomization

5. No leptomeningeal disease

4. Uncontrolled pleural effusion, pericardial effusion, or ascites. Patients with indwelling catheters (e.g., PleurX®) are allowed

5. Uncontrolled tumor-related pain. Patients requiring narcotic pain medication must be on a stable regimen at study entry. Symptomatic lesions (e.g., bone metastases or metastases causing nerve impingement) amenable to palliative radiotherapy should be treated prior to randomization. Asymptomatic metastatic lesions whose further growth would likely cause functional deficits or intractable pain (e.g., epidural metastasis that is not presently associated with spinal cord compression) should be considered for loco-regional therapy if appropriate prior to randomization

6. Ionized calcium > 1.2 x UNL. The use of bisphosphonates is allowed

7. Pregnant or breastfeeding

9. Significant cardiovascular disease, such as New York Heart Association (NYHA) cardiac disease (Class II or greater), myocardial infarction within 3 months prior to randomization, unstable arrhythmias, or unstable angina Patients with a known left ventricular ejection fraction (LVEF) < 40% will be excluded. Patients with known coronary artery disease, congestive heart failure not meeting the above criteria, or LVEF < 50% must be on a stable medical regimen that is optimized in the opinion of the treating physician, in consultation with a cardiologist if appropriate

10. Severe infection within 21 days prior to randomization, requiring hospitalization
