Trial Outcomes & Findings for A Phase III Randomized Trial of Metformin vs Placebo in Early Stage Breast Cancer (NCT NCT01101438)

NCT ID: NCT01101438

Last Updated: 2023-09-13

Results Overview

Invasive disease-free survival (IDFS) is defined as percentage of patients without documented development of ipsilateral and contralateral invasive breast tumour, local/regional invasive recurrence, distant recurrence, death from any causes. If a subject has not had invasive disease or died at the time of data cut-off for this final analysis, IDFS was censored on the date of last follow-up.
