Inclusion and exclusion criteria

Inclusion Criteria

• Provision of written informed consent prior to study entry
• Female participants aged at least 18 years
• Post-menopausal status defined as meeting at least one of the following criteria:
(a) Have undergone a bilateral oophorectomy
(b) Age ≥ 60 years
(c) Age ≥ 50 and < 60 years and with cessation of menses ≥ 12 months and follicle-stimulating hormone and oestradiol levels in the post-menopausal range and with an intact uterus in the absence of oral contraception or hormone replacement therapy prior to the diagnosis of breast cancer
• Female participants with newly diagnosed primary breast cancer scheduled to undergo treatment with curative intent by surgery and irrespective of clinical node status
• Histologically confirmed invasive breast cancer involving a palpable tumour of any size, or a tumour with an ultrasound assessed diameter of ≥ 1.0 cm
• Participants with adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumours curatively treated with no evidence of disease for ≥ 3 months can be considered for the study
• According to the local laboratory participants must have:
(a) ER positive breast cancer
(b) HER2-negative breast cancer
• Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1

Exclusion Criteria

• Previous systemic or local treatment for the new primary breast cancer currently under investigation (including surgery, radiotherapy, cytotoxic and endocrine treatments)
• Intervention with any of the following:
a) Use of sex-hormone-containing drugs within 6 months prior to the first dose of study treatment
b) Medications or herbal supplements known to be strong inhibitors/inducers of CYP3A4/5, sensitive CYP2B6 substrates and drugs which are substrates of CYP2C9 and/or CYP2C19 which have a narrow therapeutic index
c) Drugs that are known to prolong QT and have a known risk of torsades de pointes
• Inflammatory breast cancer
• Any evidence of severe or uncontrolled systemic diseases which in the investigator’s opinion makes it undesirable for the participant to participate in the study
• Any of the following cardiovascular criteria: Mean resting QTcF > 470 msec; resting heart rate of < 50 bpm for stages 1 and 2 at screening;resting heart rate <60 bpm at screening for Stage 3; any clinically important abnormalities in rhythm, conduction, or morphology of resting ECG; any factors that increase the risk of QTc prolongation or risk of arrhythmic events; known left ventricular ejection fraction < 50%; significant cardiovascular procedure or event within the last 6 months; uncontrolled hypertension or symptomatic hypotension
• Inadequate bone marrow reserve or organ function
• Refractory nausea and vomiting, uncontrolled chronic gastrointestinal diseases, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption of AZD9833
• History of hypersensitivity to active or inactive excipients of AZD9833
• Previous randomisation in the present study
• Judgement by the Investigator that the participant should not participate in the study if the participant is unlikely to comply with study procedures, restrictions and requirements
