A Pilot, Single-Arm, Phase II Trial of Tamoxifen Plus Pegylated Liposomal Doxorubicin in Patients With Metastatic Triple Negative Breast Cancer
Roswell Park Cancer Institute
Summary
This phase II trial tests how well tamoxifen and pegylated liposomal doxorubicin works in treating patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or that has spread to nearby tissue or lymph nodes (locally advanced) and is unable to be operated on (inoperable). Tamoxifen works by blocking the effects of estrogen in the breast. This may help stop the growth of tumor cells that need estrogen to grow. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Liposomal doxorubicin is a form of the anticancer drug doxorubicin that is contained inside very tiny, fat-like particles. Liposomal doxorubicin may have fewer side effects and work better than other forms of the drug. Giving tamoxifen and pegylated liposomal doxorubicin together may work better in treating patients with metastatic or inoperable, locally advanced triple negative breast cancer than giving either of these drugs alone.
Description
PRIMARY OBJECTIVE: I. To determine the efficacy of the combination of tamoxifen and pegylated liposomal doxorubicin in patients with metastatic or inoperable locally advanced triple negative breast cancer (TNBC) (estrogen receptor \[ER\] \< 10%) as assessed by overall response rate (ORR) as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. SECONDARY OBJECTIVES: I. To assess the safety and tolerability of pegylated liposomal doxorubicin given in combination with tamoxifen. II. To determine clinical benefit including overall and progression free survival (over…

Inclusion Criteria: * Patients with pathologically confirmed metastatic triple negative breast cancer (ER ≤ 10%) that have been previously treated with at least 2 lines of therapy in the metastatic setting * Patients must have a confirmed eligible TP53 genomic alteration, as determined by the Roswell Park Oncomine™ Precision Assay (OPA) or similar CLIA-approved assay, using either an archival metastatic tumor sample or, if unavailable, a fresh biopsy. Uncertainty about the eligibility of the TP53 genomic alteration for this study can be resolved by discussion with the study PI * Patients must…
