About this study
Official title: Age-Related Changes in Nanoparticle Albumin Bound (Nab) Paclitaxel Pharmacokinetics and Pharmacodynamics
RATIONALE: Gathering information from patients of different ages receiving paclitaxel albumin-stabilized nanoparticle formulation for metastatic breast cancer may help doctors understand how the age of the patient changes the way the drug works.
PURPOSE: This phase II trial is studying how well paclitaxel albumin-stabilized nanoparticle formulation works in treating patients of different ages with metastatic breast cancer.
Read the detailed description
OBJECTIVES:
Primary
- To determine age-related changes in the pharmacokinetics (pK) of weekly paclitaxel albumin-stabilized nanoparticle formulation (nab-paclitaxel) in patients with metastatic breast cancer.
- To determine age-related changes in the pharmacodynamics (toxicity) of nab-paclitaxel in these patients.
Secondary
- To determine response and time to progression in these patients.
- To explore predictors of pK parameters in these patients.
- To explore predictors of the need for dose reduction, dose delays, or grade 3 or 4 toxicity in these patients.
OUTLINE: Patients are stratified by age in years (< 50 vs 50-60 vs 60-70 vs > 70).
Patients receive paclitaxel albumin-stabilized nanoparticle formulation IV over 30 minutes once daily on days 1, 8, and 15 as planned. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
Blood is drawn for pharmacokinetic studies periodically during course 1.
Patients complete questionnaires regarding risk factors that would predict for pharmacokinetic parameters at baseline, prior to the third course of treatment, and at end of study. Data collected include medical characteristics, demographics, functional status, comorbidity, psychological status, social functioning and support, nutritional status, and cognition.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Area Under the Curve Over 24 Hours (AUC24)
Mean of area under the curve over 24 hours (AUC24) reported as well as linear regression of AUC24 by age and chemotherapy toxicity risk score.
Chemotherapy toxicity risk score is based on the following variables and the value assigned to them. Higher scores indicate more risk, range of 2-19:
patient age (>=72 years); creatinine clearance (<34 mL/min); presence of amenia (<10 g/dL); hearing impairment; falls in the last 6 months; need for assistance with taking medications; limitations in walking one block; decreased social activities; chemotherapy dosing; number of chemotherapy drugs; cancer type
Measured: Cycle 1, week 1 at 0, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 24 hours post treatment
Mean Clearance (CL)
Mean CL reported as well as regression results of CL by age and chemotherapy toxicity risk score.
Chemotherapy toxicity risk score is based on the following variables and the value assigned to them. Higher scores indicate more risk, range of 2-19:
patient age (>=72 years); creatinine clearance (<34 mL/min); presence of amenia (<10 g/dL); hearing impairment; falls in the last 6 months; need for assistance with taking medications; limitations in walking one block; decreased social activities; chemotherapy dosing; number of chemotherapy drugs; cancer type
Measured: Cycle 1, week 1 at 0, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 24 hours post treatment
Secondary outcomes (6)
Grade 3 Toxicity Rate by Chemotherapy Toxicity Risk Score
Comparison of presence of grade 3 toxicity rate by risk score distribution.
Chemotherapy toxicity risk score is based on the following variables. Higher scores indicate more risk, range of 2-19:
patient age (>=72 years); creatinine clearance (<34 mL/min); presence of amenia (<10 g/dL); hearing impairment; falls in the last 6 months; need for assistance with taking medications; limitations in walking one block; decreased social activities; chemotherapy dosing; number of chemotherapy drugs; cancer type
Chemotherapy toxicity risk score category:
Low risk score - toxicity risk score: 0-5 Medium risk score - toxicity risk score: 6-9 High risk score - toxicity risk score: 10-19
Measured: Up to 2.5 years
Best Response
Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
Measured: Assessed after every 2 cycles of therapy until progression, up to 2.5 years
Median Event-free Survival (EFS) in Months
Median and associated 95% exact Clopper and Pearson binomial confidence limits will be estimated for EFS. EFS will be estimated using the product limit method of Kaplan and Meier.
EFS is defined by time to disease recurrence, disease progression or death to due to any cause
Measured: From the date treatment begins until the first date on which recurrence, progression or death due to any cause, assessed up to 3.5 years
Number of Participants Requiring Dose Reductions
Number of participants requiring a dose reduction is reported and analysis was performed using a student's 2 sample t test to determine the need of dose reductions based on age, AUC, and CL.
Measured: At the completion of treatment, up to 2.5 years
Number of Participants With a Dose Omission
Number of participants with a dose omission is reported and analysis was performed using a student's 2 sample t test to determine the need of dose omission based on age, AUC, and CL.
Measured: At the completion of treatment, up to 2.5 years
Percent of Participants With a Grade 3 Toxicity
Percent of participants experiencing a grade 3 toxicity is reported and analysis was performed using a student's 2 sample t test to determine the presence of grade 3 toxicity based on age, AUC, and CL.
Measured: At the completion of treatment, up to 2.5 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing paclitaxel albumin-stabilized nanoparticle formulation, pharmacological study and physiologic testing in people with Breast Cancer, run by City of Hope Medical Center at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 4 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Aug 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean Area Under the Curve Over 24 Hours (AUC24) (time frame: Cycle 1, week 1 at 0, 0.25, 0.5, 1, 1.5, 2, 4, 6, 8, 24 hours post treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00609791, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jun 2026.
