Overview

This phase II trial studies the side effects of nab-paclitaxel in treating older patients with breast cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced) or to other places in the body (metastatic). Drugs used in chemotherapy, such as nab-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.

PRIMARY OBJECTIVE: I. To evaluate the tolerability (grade 2-5 toxicity, neuropathy grade 2 or higher, need for dose reductions, or delays) of weekly nab-paclitaxel in older adults with locally advanced or metastatic breast cancer. SECONDARY OBJECTIVES: I. To evaluate the efficacy (response and time to progression) of weekly nab-paclitaxel in older adults with locally advanced or metastatic breast cancer using a stratification factor based on patient age (at least 5 patients age 75 years or older and no more than 15 patients age 65-70 years). II. To explore predictors of the need for dose reduction, dose delays, or grade 2-5 toxicity and neuropathy grade 2 or higher based on a cancer-specific geriatric assessment. OUTLINE: Patients receive nab-paclitaxel intravenously (IV) over 30 minutes 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 periodically.

Outcomes

Primary Outcomes

Percent of Participants With Grade 2-5 Toxicity Using National Cancer Institute Common Toxicity Criteria Version 4.0

Will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Rates and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for grade 2 or higher toxicities attributed to treatment.

Time frame: During and after treatment, up to 2.5 years

Percent of Participants With Grade 3 or Higher Toxicities Attributable to Treatment

Time frame: On treatment, 28 days per cycle up to 30 months

Rate of Participants With a Dose Reduction

Rates and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for dose reduction.

Time frame: On treatment, up to 30 months

Rate of Participants Requiring Dose Holds

Rates and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for dose reduction.

Time frame: While on treatment, up to 30 months

Secondary Outcomes

Response Determined by Response Evaluation Criteria in Solid Tumors

Rates and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for objective response rate (complete response \[CR\] + partial response \[PR\]). RECIST: Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to \<10 mm Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. Additionally, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study

Time frame: Up to 2.5 years

Median Progression Free Survival (PFS)

PFS will be estimated using the product limit method of Kaplan and Meier.

Time frame: From the date treatment begins until the first date on which recurrence, progression, or death due to any cause, assessed for about 1.5 years

Cancer-specific Geriatric (CARG) Assessment

General linear models and descriptive methods will be used to explore factors as identified by a CARG assessment that may be predictive of toxicity (grade 3 or higher adverse events) or dose reduction. The cancer specific geriatric assessment score includes an evaluation of functional status, co-morbidity, cognition, psychological stats, social functioning and support, and nutritional status. It assesses a patient's age, gender, height, weight, cancer type, dosage, number of chemotherapy agents, hemoglobin, hearing, number of falls in past 6 months, able to take own medicine, whether walking is limited, have physical or emotional problems interfered with social activities and serum creatinine. Scores can range from 0 to to 1, with a higher score indicating higher risk of chemotherapy toxicity. Scores from 0 to 5 are considered low risk, 6 to 9 are considered intermediate risk, and 10 to 19 are considered high risk.

Time frame: CARG measured prior to treatment, toxicities and dose reduction measured up to 30 months
