A phase II study evaluating efficacy and safety of Ipilimumab and Nivolumab with neoadjuvant weekly paclitaxel after anthracycline based chemotherapy in high-risk primary triple negative breast cancer, followed by definitive surgery and one year total duration of Nivolumab (BCT 1702 CHARIOT)

Breast Cancer Trials (BCT)

Dataset description

* Dataset of 34 patients with high risk primary triple negative breast cancer suitable for neoadjuvant treatment after treatment with 4 cycles anthracycline-based chemotherapy. * Study treatment for 12 weeks with Nivolumab for 6 doses; Ipilimumab for 2 doses; paclitaxel weekly for 12 doses. * Surgery withn 4 weeks of last paclitaxel dose. * Followed by nivolumab every 4 weeks for up to 1 year. * Survival follow up at 24 months and 36 months from cycle 1 day 1. * pCR, residual diseae, objective response rate data. * Safety/toxicity, event free survival, overall survival data. * ctDNA data.

Brief Summary

This study aims to find out if treatment with a combination of Ipilimumab and Nivolumab, with weekly paclitaxel before surgery, and treatment with Nivolumab after surgery, is safe and effective in women and men diagnosed with triple negative breast cancer. Who is it for? You may be eligible for this study if you are 18 years or older, have been diagnosed with triple negative breast cancer, will be having neoadjuvant treatment (treatment with anthracycline-based chemotherapy before surgery) and y ....
