This phase I / II trial studies the side effects and best dose of copanlisib and how well it works when given together with eribulin in treating patients with triple negative breast cancer that has spread to other places in the body (advanced stage). Copanlisib stops the growth of a protein called PI3K, which is often changed in tumor cells and causes resistance to treatment. Chemotherapy drugs, such as eribulin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving copanlisib and eribulin may work better in treating advanced stage triple negative breast cancer compared to eribulin alone.

This is a Phase Ib / II, open-label, multicenter, randomized umbrella study evaluating the efficacy and safety of multiple immunotherapy-based treatment combinations in patients with metastatic or inoperable locally advanced TNBC. The study will be performed in two stages. During Stage 1, two cohorts will be enrolled in parallel in this study: one cohort will consist of Programmed death-ligand 1 (PD-L1)-positive participants who have received no prior systemic therapy for metastatic or inoperable locally advanced triple-negative breast cancer (TNBC) (first-line [1L] PD-L1+ cohort), and one cohort will consist of participants who had disease progression during or following 1L treatment with chemotherapy (e.g., paclitaxel, nab-paclitaxel, carboplatin) and have not received cancer immunotherapy (CIT) (second-line [2L] CIT-naive cohort). In addition, participants in the 2L CIT-naive cohort who experience disease progression, loss of clinical benefit, or unacceptable toxicity during Stage 1 may be eligible to continue treatment with a different treatment combination (Stage 2), provided Stage 2 is open for enrollment.
