Trial details

UNIRAD is an international, double blind, multicentre, phase III randomised trial to evaluate the benefit of adding 2 years of everolimus to standard endocrine treatments for patients with high risk of relapse, ER+, HER2- primary, non-metastatic breast cancer, who remain disease free after 1–4 years of adjuvant endocrine therapy.

1,984 patients will be recruited from participating sites in France, Belgium and the UK to receive either everolimus or placebo for 2 years, in addition to ongoing standard care endocrine therapy lasting up to a total of 5 years. Following completion of treatment, participants will be followed up for a further 5 years.
