Clinical Trial Summary

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.

Description:

PRIMARY OBJECTIVE: I. To determine if the combination of radium-23 dichloride (radium Ra 223 dichloride) and paclitaxel improves progression-free survival (PFS) compared to paclitaxel alone. SECONDARY OBJECTIVES: 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). EXPLORATORY OBJECTIVES: I. To perform molecular profiling assays on malignant and normal tissues, including, but not limited to, whole exome sequencing (WES) and messenger ribonucleic acid (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 of each cycle. 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. Patients also undergo computed tomography (CT) scan, bone scan and/or magnetic resonance imaging (MRI), as well as collection of blood samples throughout trial. Patients may optionally undergo single photon emission computed tomography (SPECT) on trial. ARM II: Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT scan, bone scan, and/or MRI, as well as collection of blood samples throughout trial. Patients may optionally undergo SPECT on trial. After completion of study treatment, patients are followed up at 30 days, then every 3 months for 2 years.

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to radium-223 dichloride or other agents used in study
• Patients with psychiatric illness/social situations that would limit compliance with study requirements
• 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

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Molecular profiling assays on malignant and normal tissues	Whole exome sequencing and messenger ribonucleic sequencing will be described qualitatively or quantitatively.	At baseline
Primary	Progression-free survival (PFS)	Tumor progression will be determined from radiographic scans performed every 8 weeks (computed tomography and bone scan) using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. The log-rank test will be used to analyze PFS for comparison of treatment effects, i.e., the only covariate that will be used is the treatment arm. Distributions of PFS times will be estimated using the Kaplan-Meier product-limit method.	From randomization to the first documented tumor progression or death due to any cause, whichever occurred first, assessed up to 2 years
Secondary	PFS	Treatment comparison in PFS will be conducted in pre-defined subgroups, including hormone receptor status and presence/absence of visceral metastases and two-sided 80% confidence intervals (CIs) will be provided for each subgroup.	From randomization to the first documented tumor progression or death due to any cause, whichever occurred first, assessed up to 2 years
Secondary	Time to first symptomatic skeletal event (SSE)	Will be defined as the first 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. Distributions of time to SSE will be estimated using the method of Kaplan-Meier and compared between treatment arms using the stratified log-rank test.	From randomization to the occurrence of the first SSE, assessed up to 2 years
Secondary	Objective response rate	Will be defined as the proportion of all subjects with confirmed partial response or complete response according to RECIST 1.1.	From start of treatment until disease progression, assessed up to 2 years
Secondary	Overall survival (OS)	The log-rank test will be used as the primary analysis for comparison of treatment effects, i.e., the only covariate that will be used is the treatment arm. Distributions of OS times will be estimated using the Kaplan-Meier product-limit method. The median OS times with two-sided 95% CIs will be estimated for each treatment group.	From randomization to death due to any cause, assessed up to 2 years
Secondary	Incidence of adverse events (AEs)	Will be assessed by grading all treatment-related AEs and events of clinical interest according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Grade 3 or higher diarrhea or constipation are ECI for the proposed trial. Adverse events will be summarized according to grade, overall and by treatment arm, as number and percentage of participants. All adverse events resulting in discontinuation, dose modification, and/or dosing interruption, and/or treatment delay of drug will also be summarized by treatment arm.	Up to 30 days after end of study treatment
