Triple Negative Breast Cancer, Nivolumab, Capecitabine
Brief summary
This pilot study will provide preliminary data regarding the role of PIS in predicting the benefit of immune checkpoint inhibition with or without chemotherapy for high risk patients with TNBC and residual disease after effective neoadjuvant chemotherapy.
Interventions
Nivolumab is a human programmed death receptor-1 (PD-1) antibody currently approved in different diseases.
Capecitabine was selected for Arm B given the recent results from CREATE-X trial and the increasing use by the community (feasibility). Importantly, available data from other scenarios indicates that capecitabine does not have immunosuppressive effects

|---|---|---|
| Percent Change in the Peripheral Immunoscore (PIS) at Week 6 | 6 weeks | PIS were developed using methods previously described (Farsaci, B. et al. Cancer Immunol. Res. 2016), based on tertile distribution of frequencies and ratios of peripheral immune cell subsets in patients prior to therapy. Immune subsets were calculated as a % of PBMC and sorted by frequency. Points were assigned to each subset in a given patient based on tertile distribution. For subsets with an expected positive effect on anti-tumor immunity zero (0) points were assigned to the low bin, one (1) point for the middle bin, and two (2) points if in the high bin. For subsets with an expected negative effect on anti-tumor immunity zero (0) points were assigned to the high bin, one (1) point for the middle bin, and two (2) points if in the low bin. The peripheral immunoscore for a given patient was the sum of points assigned to the individual PBMC subsets that were included within the immunoscore. Positive change means enhanced and negative change means reduced immune function. |
