Current Primary Outcome Measures (submitted: November 29, 2023)

Invasive disease-free survival (iDFS) for Dato-DXd + durvalumab vs. ICT [ Time Frame: From randomisation to date of the event, up to 57 months from first subject in ]

iDFS is defined as time from randomisation until date of first occurrence of one of the following events: ipsilateral invasive breast tumour (local) recurrence, regional invasive breast cancer recurrence (axilla, regional lymph nodes, chest wall, and skin of ipsilateral breast), or distant recurrence (metastatic breast cancer that has either been biopsy-confirmed or clinically diagnosed as recurrent invasive breast cancer); contralateral invasive breast cancer; second primary non-breast invasive cancer (other than squamous or basal cell skin cancer); or death from any cause. iDFS will be determined based on disease recurrence per investigator assessment based on all available clinical assessments. The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy or receives another anticancer therapy. The measure of interest will be the HR (hazard ratio) of iDFS for Dato-DXd + durvalumab vs ICT.
