Andre expanded on this in an interview with OncLive during the 35th Annual Miami Breast Cancer Conference.
The first question with immunotherapy is determining the prevalence of patients with triple-negative breast cancer that are sensitive to PD-L1, Andre explains; it currently is estimated to be 25% of patients in the first-line setting. Secondly, robust data emerging that, when a tumor is presenting with lymphocytic infiltration, the patient is more likely to be sensitive to immunotherapy.
Researchers are also seeking to improve the response rates currently reported with single-agent immunotherapy, Andre says. Currently, data in the neoadjuvant setting demonstrate that single-agent PD-1 therapy combined with chemotherapy. Until now, there are not phase III trial data in the first-line setting, but they are highly anticipated by the community, he concludes.
