Eligibility
Key inclusion criteria
* Women and Men; =18 years at the time of screening (or per national guidelines)
* Histologically confirmed ER+/HER2- early-stage resected invasive breast cancer with absence of any evidence of metastatic disease as defined in the protocol.
* Completed adequate (definitive) locoregional therapy (surgery with or without radiotherapy) for the primary breast tumour(s), with or without (neo)adjuvant chemotherapy.
* Patients must be randomised within 12 months of definitive breast surgery.
* Patients may have received up to 12 weeks of endocrine therapy prior to randomisation.
* Eastern Cooperative Oncology Group (ECOG) performance status of = 1
* Adequate organ and bone marrow function
Minimum age
18 Years
Maximum age
130 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Inoperable locally advanced or metastatic breast cancer
* Pathological complete response following treatment with neoadjuvant therapy
* History of any other cancer (except non-melanoma skin cancer or carcinoma in situ of the cervix or considered a very low risk of recurrence per investigator judgement) unless in complete remission with no therapy for a minimum of 5 years from the date of randomisation
* Any evidence of severe or uncontrolled systemic diseases which, in the investigator's opinion precludes participation in the study or compliance "
* Known LVEF <50% with heart failure NYHA Grade =2.
* Mean resting QTcF interval > 480 ms at screening
* Concurrent exogenous reproductive hormone therapy or non topical hormonal therapy for non-cancer-related conditions
* Any concurrent anti-cancer treatment not specified in the protocol with the exception of bisphosphonates (e.g. zoledronic acid) or RANKL inhibitors ( eg, denosumab)
* Previous treatment with camizestrant, investigational SERDs/investigational ER targeting agents, or fulvestrant
* Currently pregnant (confirmed with positive serum pregnancy test) or breastfeeding.
* Patients with known hypersensitivity to active or inactive excipients of camizestrant or drugs with a similar chemical structure or class to camizestrant. In pre-/peri-menopausal female and male patients, known hypersensitivity or intolerance to LHRH agonists that would preclude the patient from receiving any LHRH agonist.
