Resumen

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.

Descripción detallada

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 of the study is 7 years. Eligible patients must have intermediate-high or high risk of recurrence as defined by specified clinical and biologic criteria. Concurrent use of abemaciclib is permitted in both arms. The primary endpoint of the study is Invasive breast cancer-free survival (IBCFS) and main secondary endpoints include Invasive disease-free survival (IDFS), Distant relapse-free survival (DRFS), Overall survival (OS), Safety and Clinical Outcome Assessments (COAs). Patients will be followed for 10 years from randomization of the last patient.

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.

Criterios de exclusión

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.
