Breast Cancer Clinical Trial
Testing the Addition of Radium Therapy (Radium-223 Dichloride) to the Usual Chemotherapy Treatment (Paclitaxel) for Advanced Breast Cancer That Has Spread to the Bones
This phase II trial studies how well radium-223 dichloride and paclitaxel work in treating patients with advanced breast cancer that has spread to the bones. Radium-223 dichloride is a radioactive drug that behaves in a similar way to calcium and collects in cancer that has spread to the bones (bone metastases). The radioactive particles in radium-223 dichloride act on bone metastases, killing the tumor cells and reducing the pain that they can cause. Drugs used in chemotherapy, such as paclitaxel, 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 radium-223 dichloride and paclitaxel may work better in treating patients with metastatic breast cancer compared to paclitaxel alone.
I. To determine if the combination of radium Ra 223 dichloride (radium-223 dichloride) and paclitaxel improves progression-free survival (PFS) compared to paclitaxel alone.
I. To determine the time to the first symptomatic skeletal event (SSE) (defined as 1st use of radiation therapy to relieve skeletal symptoms, new symptomatic pathologic vertebral or non-vertebral bone fractures, spinal cord compression, or tumor-related orthopedic surgical intervention).
II. To measure the objective response rate (ORR). III. To determine the safety of radium-223 dichloride with paclitaxel. IV. To measure overall survival (OS).
I. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to, whole exome sequencing (WES) and messenger ribonucleic (RNA) sequencing (RNAseq), in order to:
Ia. Investigate if molecular alterations in deoxyribonucleic acid (DNA) repair genes are associated with response to radium-223 dichloride, and.
Ib. Investigate if loss of heterozygosity in triple negative tumors is associated with response to radium-223 dichloride.
II. To contribute genetic analysis data from de-identified biospecimens to Genomic Data Commons (GDC), a well annotated cancer molecular and clinical data repository, for current and future research; specimens will be annotated with key clinical data, including presentation, diagnosis, staging, summary treatment, and if possible, outcome.
III. To correlate change in level of total alkaline phosphatase, bone-specific alkaline phosphatase, and serum osteocalcin to response to radium-223 dichloride therapy.
IV. To examine the radium-223 dichloride bio-distribution and absorbed dose in each bone metastatic lesions as well as elsewhere in the body including critical organs using dosimetry.
V. To bank formalin-fixed, paraffin-embedded (FFPE) tissue, blood, and nucleic acids obtained from patients at the Experimental Therapeutics Clinical Trials Network (ETCTN) Biorepository at Nationwide Children's Hospital.
VI. To explore the symptomatic adverse events (AE) for tolerability of each treatment arm.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive paclitaxel intravenously (IV) over 1 hour on days 1, 8, and 15 and radium Ra 223 dichloride IV over 1 minute on day 1. Treatment with radium Ra 223 dichloride repeats every 28 days for 6 cycles and treatment with paclitaxel repeats every 28 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 3 months for 2 years.

Hormone receptor status will be determined at the local institution. ER and PR negativity will be defined as < 1% tumor staining by IHC
Patient must be eligible to receive therapy with paclitaxel for the treatment of their breast cancer. Patients with hormone-receptor positive disease should have progressed on at least one prior line of hormone therapy and a CDK4/6 inhibitor in the metastatic setting to be eligible (except if patient had a contraindication or intolerable toxicity with the use of these agents).

The effects of radium-223 dichloride on the developing human fetus are unknown. For this reason and because alpha particle-emitting radiopharmaceutical agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for at least 6 months after the last dose. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Pre-menopausal subjects as well as subjects with ovarian radiation or concomitant treatment with an LH-RH agonist/antagonist must have a negative pregnancy test and agree to use an adequate method of contraception as recommended by their treating physicians. Subjects of child-bearing potential who are sexually active and their male partners must agree to utilize, during the treatment period and for 6 months after last dose of radium-223 dichloride, 2 reliable and acceptable methods of contraception used simultaneously: a) barrier method such as a) condoms (male or female) with spermicidal agent or b) diaphragm or cervical cap with spermicide, combined with a highly effective non-hormonal birth control method such as an intra-uterine device. Men treated or enrolled on this protocol must also agree to use adequate contraception and not donate sperm prior to the study, for the duration of study participation, and 6 months after completion of Radium-223 dichloride

Pregnant women are excluded from this study because radium-223 dichloride is an alpha particle-emitting radiopharmaceutical agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for AEs in nursing infants secondary to treatment of the mother with radium-223 dichloride, breastfeeding should be discontinued if the mother is treated with radium-223 dichloride. These potential risks may also apply to other agents used in this study
