Breast Cancer, Early Breast Cancer Clinical Trial
— CAMBRIA-2Official title:
CAMBRIA-2: A Phase III, Open-Label, Randomised Study to Assess the Efficacy and Safety of Camizestrant (AZD9833, a Next Generation, Oral Selective Estrogen Receptor Degrader) vs Standard Endocrine Therapy (Aromatase Inhibitor or Tamoxifen) as Adjuvant Treatment for Patients With ER+/HER2- Early Breast Cancer and an Intermediate-High or High Risk of Recurrence Who Have Completed Definitive Locoregional Treatment and Have No Evidence of Disease
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 | 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. |
