简要总结
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.
详细描述
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).

Hormone-receptor positive (estrogen receptor [ER]-positive and/or progesterone receptor [PR]-positive) as well as triple-negative (ER-negative, PR-negative and no overexpression of HER2) breast cancer may be enrolled. 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). Previous radiation and chemotherapy for the treatment of metastatic breast cancer is allowed
- •Age >= 18 years
- •Because no dosing or AE data are currently available on the use of radium-223 dichloride in combination with paclitaxel in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials

- •Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial. History of other active malignancy requiring treatment within the last 3 years or bone marrow dysplasia such as myelodysplastic syndrome (MDS) is not allowed
- •Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association functional classification. To be eligible for this study, patients should be class 2B or better
- •Concomitant use of bisphosphonates or denosumab is required (except if medical contraindication such as hypocalcemia or concern for osteonecrosis of the jaw). If not already on bone modifying agents, patient must initiate such therapy within one month before start of study treatment
- •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 luteinizing hormone-releasing hormone (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

- •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

结局指标
主要结局
Progression-free survival (PFS)
时间窗: From randomization to the first documented tumor progression or death due to any cause, whichever occurred first, assessed up to 2 years
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.
次要结局
- Objective response rate(From start of treatment until disease progression, assessed up to 2 years)
- PFS(From randomization to the first documented tumor progression or death due to any cause, whichever occurred first, assessed up to 2 years)
- Overall survival (OS)(From randomization to death due to any cause, assessed up to 2 years)
- Incidence of adverse events (AEs)(Up to 30 days after end of study treatment)
- Time to first symptomatic skeletal event (SSE)(From randomization to the occurrence of the first SSE, assessed up to 2 years)
