A randomised phase III trial of carboplatin compared to docetaxel for patients with metastatic or recurrent locally advanced ER–, PR– and HER2– breast cancer.

Disease site: Breast cancer

Treatment modality: Systemic therapy (chemotherapy)

Status: In follow-up

Trial details

TNT – the ‘Triple Negative Trial’ – is a phase III, multicentre, randomised trial designed to determine whether carboplatin demonstrates greater activity than docetaxel (the current standard of care taxane chemotherapy) in women with either triple negative (ER–, PR– and HER2–) or BRCA1 / BRCA2 mutation associated breast cancer. Translational research incorporated as part of TNT will aim to optimise existing drugs and find new targets for therapy in these breast cancer subtypes.

TNT enrolled its first patients in 2008 and closed to recruitment in March 2014 after reaching its recruitment target and recruiting 376 women. Participants were randomly allocated to receive either carboplatin or docetaxel, and crossed over to receive the alternative treatment upon disease progression.
