About this study

Official title: Phase II Trial of Sorafenib and Paclitaxel for Measurable Metastatic HER2-Negative Breast Cancer

RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with paclitaxel may kill more tumor cells.

PURPOSE: This phase II trial is studying the side effects of giving sorafenib together with paclitaxel and to how well it works in treating patients with metastatic breast cancer.

Read the detailed description

OBJECTIVES:

Primary

  • To evaluate the efficacy of sorafenib tosylate and paclitaxel by measuring tumor response, as defined by RECIST criteria, in patients with metastatic, HER2-negative breast cancer.

Secondary

  • To evaluate time to disease progression in patients treated with this regimen.
  • To evaluate six-month progression-free survival of patients treated with this regimen.
  • To evaluate time to treatment failure in patients treated with this regimen.
  • To evaluate clinical benefit rate (tumor response and stable disease) at 24 weeks in patients treated with this regimen.
  • To evaluate duration of response in patients treated with this regimen.
  • To evaluate the tolerability of this regimen in these patients.
  • To examine the relationship of gene expression and tissue/serum protein markers, where available, related to response to therapy focusing on growth factor receptor pathways.

OUTLINE: This is a multicenter study.

Patients receive oral sorafenib tosylate twice daily on days 1-28 and paclitaxel IV over 1 hour on days 1, 8, and 15. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed at 4 weeks.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to Tumor Progression

    Progression-free survival was defined as the time of treatment to the earliest date of documentation of disease progression or death due to any cause. In the case of a participant started treatment. Tenth month of progression-free rate of sorafenib and paclitaxel will be compared agains the null progression free rate of 32% using normal approximation test.

    Measured: Time from first treatment to disease progression or death (up to 36 months)

Secondary outcomes (7)
  1. Tumor Response Rate

    Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by CT and MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions. The confirmed response rate was estimated by the number of confirmed responses divided by the total number of participants randomized.

    Measured: Up to 36 months

  2. Six-month Progression-free Survival

    The proportion of patients with progression-free survival at 6 months. Progression-free is measured from Day-1 of study drug administration to disease progression as defined by Response Evaluation Criteria in Sole Tumors (RECIST) v1.1, or death on study. Progression is defined in RECIST v1.1 as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new leasions.

    Measured: 6 months

  3. Time to Treatment Failure

    Number of patients experiencing treatment failure.

    Measured: Up to 36 months

  4. Clinical Benefit Rate (Tumor Response and Stable Disease) at 24 Weeks

    Number of patients with either complete response (CR) or partial response (PR) as defined in Response Evaluation Criteria in Solid Tumors (for patients with measurable disease). Complete Response: Disappearance of all target lesions, disappearance of all non-target lesions for at least 4 weeks. Partial Response: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum of longest diameters.

    Measured: 24 weeks

  5. Duration of Response

    Number weeks until disease progression measured from Day-1 of study drug administration to disease progression.

    Measured: Up to 36 months

  6. Tolerability of Sorafenib/Paclitaxel Regimen

    Number of patients without experiencing treatment-related adverse events.

    Measured: Up to 36 months

  7. Determine the Relationship of Gene Expression and Tissue/Serum Protein Markers, Where Available, Related to Response to Therapy Focusing on Growth Factor Receptor Pathways.

    Median values taken for all assays at baseline and relationship to response vs. no response will be made to identify predictive markers using methods to detect differential expression between two groups samples, including variants of the two-sample t-test, analysis of variance, F-test, and the Wilcoxon rank-sum test.

    Measured: Up to 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing paclitaxel and sorafenib tosylate in people with Breast Cancer, run by University of Texas Southwestern Medical Center at 1 site 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 25 inclusion and 31 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: stopped early, as of the sponsor's last update on 19 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 19 Oct 2020). 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?

Time to Tumor Progression (time frame: Time from first treatment to disease progression or death (up to 36 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Oct 2020.
