About this study

Official title: BRE-01: Phase 2 Trial of Neoadjuvant Weekly Carboplatin Plus Paclitaxel Followed by Doxorubicin and Cyclophosphamide in Triple Negative Breast Cancer

Nonrandomized, open label, single arm, Simon's two stage MinMax design trial of neoadjuvant weekly carboplatin plus paclitaxel, followed by doxorubicin and cyclophosphamide in patients with operable Triple Negative Breast Cancer (TNBC)

Read the detailed description

This is a single arm, Phase 2, open label, Simon's two stage MinMax design trial to evaluate the safety and efficacy of weekly carboplatin in combination with standard neoadjuvant chemotherapy in subjects with previously untreated triple negative breast cancers who are candidates for potentially curative surgery.

Subjects will receive carboplatin (Area Under the Curve (AUC) 2 mg/mL/min) + paclitaxel (80 mg/m2) Carboplantin plus Paclitaxel (CbP) followed by doxorubicin and cyclophosphamide (AC). All subjects will receive CbP on Day 1 of 12 weekly cycles (Visits CbP1 - CbP12) via infusion during Chemotherapy Segment 1 as indicated in the Study Schema. Dose interruptions and dose modifications are allowed based upon tolerability and may extend Chemotherapy Segment 1 duration to a maximum of 16 weeks. Beginning with Chemotherapy Segment 2 all subjects will receive doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) on Day 1 of four 14-day cycles (Visits AC1 - AC4). For subjects who experience toxicities due to carboplatin, paclitaxel, doxorubicin or cyclophosphamide, the appropriate dose modifications or dosing delays should be managed according to Section 11.2. Dose modifications may result in the total duration of therapy being greater than the planned 24 weeks. The objective of this study is to determine efficacy and tolerability of low dose, weekly carboplatin in combination with weekly paclitaxel followed by standard doxorubicin/cyclophosphamide as neoadjuvant therapy for triple-negative breast cancer.

What is being measured

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

  1. Pathological complete response (pCR) rate

    Defined as the absence of residual invasive carcinoma in the resected breast specimen and ipsilateral axillary lymph nodes following completion of neoadjuvant therapy (i.e., ypT0/Tis, ypN0 per the American joint Committee on Cancer staging system) in all subjects completing at least 1 cycle of study treatment (modified intent-to-treat population)

    Measured: 30 months

Secondary outcomes (10)

  1. Pathologic complete response rate in subjects completing protocol therapy.

    Pathologic complete response rate Defined as the absence of residual invasive carcinoma in the resected breast specimen and ipsilateral axillary lymph nodes following completion of neoadjuvant therapy (i.e., ypT0/Tis, ypN0 per the American joint Committee on Cancer staging system) will be determined in the sub-group of subjects completing at least 75% of planned treatment cycles.

    Measured: 30 months

  2. Residual Cancer Burden

    The Residual Cancer Burden (RCB) class will be estimated from routine pathologic sections of the resected primary breast tumor and the regional lymph nodes after the completion of neoadjuvant therapy. RCB class 0 represents pCR, and class I represents minimal residual invasive disease. Class II and III represent significant residual disease. We will report the rate of achieving RCB class 0/1 vs. II/III.

    Measured: 30 months

  3. Event-free survival (EFS)

    Time from enrollment to any of the following: failure to undergo potentially curative surgery; onset of local, regional, or distant invasive recurrence of breast cancer following curative surgery; second primary invasive cancer in the breast or in another organ; or death from any cause.

    Measured: 30 months

  4. Invasive disease-free survival (iDFS)

    Time from enrollment to any of the following: development of invasive cancer in the ipsilateral breast or regional nodes, contralateral breast or regional nodes, distant metastases, or death from any cause

    Measured: 30 months

  5. Distant disease-free survival (DDFS)

    Time from enrollment to documentation of distant metastases or death from any cause

    Measured: 30 months

  6. Overall survival (OS)

    Time from enrollment to death from any cause

    Measured: 30 months

  7. Clinical response to neoadjuvant chemotherapy

    Defined as progressive disease, stable disease, partial response and complete response according to RECIST 1.1 criteria in the modified intent-to-treat population and participants completing at least 75% of protocol therapy

    Measured: 30 months

  8. Breast conservation rate

    The percentage of women undergoing adequate partial mastectomy as determined by treating physicians and achieving negative pathological surgical margins (no ink on tumor).

    Measured: 30 months

  9. Treatment tolerability

    Number of cycles delayed, deleted or requiring dose reduction; number of participants who fail to complete all planned courses of protocol therapy; number of participants with treatment-related adverse events as assessed by CTCAE v5.0.

    Measured: 30 months

  10. Quality of life Measurement

    Change in score on the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 quality of life survey. This 30-item survey uses a Likert scale with total scores ranging from 30-126, with increasing scores indicating worse quality of life. We will compare mean baseline scores to scores at the end of protocol therapy, and 3 and 12 months after completing all protocol therapy.

    Measured: 30 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Carboplatin, Paclitaxel and Doxorubicin in people with Triple Negative Breast Cancer, run by University of Illinois Chicago 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 23 inclusion and 21 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 10 Jul 2025. 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?

This study is still under way. Results are not available in the source record yet.

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?

Pathological complete response (pCR) rate (time frame: 30 months). 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 NCT04083963.

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 10 Jul 2025.
