简要总结
This phase I/II trial studies side effects and best dose of copanlisib when given together with letrozole and palbociclib and to see how well they work in treating hormone receptor positive HER2 negative stage I-IV breast cancer. Copanlisib and palbociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs, such as letrozole, may lessen the amount of estrogen made by the body. Giving copanlisib, letrozole, and palbociclib may work better in treating patients with breast cancer.
详细描述
PRIMARY OBJECTIVES:
I. Assess the safety, tolerability and to estimate the maximum tolerated dose (MTD) in a metastatic setting of the following combination: copanlisib + palbociclib + letrozole. (Phase Ib) II. Compare the biological activity of letrozole in combination with palbociclib, letrozole in combination with palbociclib and copanlisib, and letrozole in combination with copanlisib by assessing the percentage change from the baseline value in Ki67 expression after 2 weeks of therapy in non-metastatic breast cancer. (Phase II)
SECONDARY OBJECTIVES:
I. Evaluate the pathologic complete response (pCR) defined as absence of invasive cancer in the breast and sampled regional lymph nodes.
II. Evaluate the clinical objective response Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.1.

结局指标
主要结局
Change in Ki-67 expression defined as the percent of cells staining positive by validated central assay (Phase II)
时间窗: Baseline to 2 weeks
Will be evaluated on the log Ki-67 ratio scale. Primary analysis of this variable will utilize a linear model with treatment, PR status as fixed effects. The comparison of treatment arms will be based on the least squares mean (LSM) estimates and standard errors derived from this model. For descriptive purposes, LSM estimates and associated confidence intervals (CIs) will be back transformed to the geometric mean percent change scale. A second post-baseline evaluation of Ki67 expression will be performed following the completion of 4 months of treatment. Analysis of change from baseline to com

If \>= 2 of 6 participants treated at a dose level experience DLTs, then the MTD will have been exceeded. Up to 3 additional patients may be entered at the lower dose level to obtain additional safety information (if only 3 participants were treated previously at that dose) to demonstrate that =\< 1 of 6 patients experience DLT.
