Brief Summary
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard adjuvant endocrine therapy for patients with ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy). The planned duration of treatment in either arm within the study will be 7 years.
Eligibility Criteria
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 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.
