Официальное название

A Phase 3 Open-Label Randomized Study Assessing the Efficacy and Safety of RLY-2608 + Fulvestrant Versus Capivasertib + Fulvestrant as Treatment for PIK3CA-mutant Hormone Receptor Positive, Human Epidermal Growth Factor Receptor 2 Negative (HR+/HER2-) Locally Advanced or Metastatic Breast Cancer Following Recurrence or Progression On or After Treatment With a CDK4/6 Inhibitor

Обзор

This is a global, multicenter, open-label, randomized Phase 3 study comparing the efficacy and safety of RLY-2608 (zovegalisib) + fulvestrant to capivasertib + fulvestrant for the treatment of patients with HR+/HER2- ABC with PIK3CA mutation following recurrence or progression on or after treatment with a CDK4/6 inhibitor.

Критерии участия

Критерии включения

Patient has ECOG performance status of 0-1
One or more known primary oncogenic PIK3CA mutation(s)
Adult females, pre- and/or post-menopausal, and adult males. Pre-menopausal (and peri-menopausal) women can be enrolled if amenable to treatment with a gonadotropin-releasing hormone (GnRH) agonist. Patients are to have commenced treatment with a GnRH agonist at least 2 weeks prior to randomization and must be willing to continue on it for the duration of the study.
Histologically or cytologically confirmed diagnosis of HR+/HER2- locally advanced or metastatic breast cancer (ABC) with radiological or objective evidence of recurrence or progression; locally advanced disease must not be amenable to resection with curative intent
Measurable disease per RECIST v1.1 or evaluable bone-only disease.
Must have radiological evidence of progression on or after previous treatment for HR+/HER2- ABC with:

At least 1 and no more than 2 lines of endocrine therapy (ET) in the (neo)adjuvant setting with recurrence on or within 12 months of completion or in the ABC setting
Only 1 prior line of CDK4/6 inhibitor therapy in one of the following settings:

CDK4/6 inhibitor + ET in the ABC setting
CDK4/6 inhibitor therapy in the adjuvant setting if progression occurred during or within 12 months of completion of adjuvant CDK4/6 inhibitor with ET
Patients who progressed during or within 12 months of completion of adjuvant CDK4/6 inhibitor and after receiving CDK4/6 inhibitor therapy in the advanced setting are considered to have had >1 prior line of CDK4/6 inhibitor and are not eligible

Критерии исключения
