Er+ Her2 Breast Cancer

ClinConnect Summary

This clinical trial is studying a new medication called camizestrant to see if it can help patients with early breast cancer that is hormone receptor-positive (ER+) and HER2-negative (HER2-). The trial is specifically looking at patients who have already completed at least 2 years of standard hormone therapy and have a higher risk of their cancer returning. Researchers want to find out if taking camizestrant for up to 5 years can improve their health outcomes compared to the usual hormone therapy.

To participate in this study, you need to be at least 18 years old and have had surgery for your breast cancer, along with other treatments like radiation or chemotherapy if required. You should have completed your initial hormone therapy and be classified as having a higher risk of recurrence based on specific medical criteria. Participants will receive camizestrant or standard hormone therapy for about 5 years, and the study is currently recruiting individuals of all genders. If you join, you can expect regular check-ups to monitor your health and response to the treatment throughout the trial.

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 high or intermediate risk of recurrence, based on clinical-pathological risk features, 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
  • Completed at least 2 years but no more than 5 years (+3 months) of adjuvant ET (+/- CDK4/6 inhibitor)
  • Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1
  • Adequate organ and 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 at 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
