Fulvestrant +/- Akt Inhibition in Advanced Aromatase Inhibitor Resistant Breast Cancer

A Phase 1b/2 Randomised Placebo Controlled Trial of Fulvestrant +/- AZD5363 in Postmenopausal Women With Advanced Breast Cancer Previously Treated With a Third Generation Aromatase Inhibitor

Source: ClinicalTrials.gov · Last updated 26 Nov 2025

Brief summary (registry, in English)

This is a two stage study, with an initial dose escalation phase I study and subsequent double blind randomised phase II controlled trial. Eligible patients are post-menopausal women with metastatic ER+ breast cancer not suitable for surgical resection. Patients should be suitable for endocrine treatment, but have received no more than 3 previous lines of endocrine treatment and up to 1 line of chemotherapy for metastatic disease. They will also have had progressive disease during treatment with an aromatase inhibitor. Following the dose-escalation in stage 1, patients will be randomised to receive fulvestrant plus either placebo or 480mg (or maximum tolerated dose) of AZD5363 oral capsules or tablets taken once daily. Patients will receive fulvestrant in combination with either placebo or AZD5363 until disease progression. Patients may continue to receive fulvestrant and AZD5363/placebo treatment even after the last trial visit.
