Study of Optimizing Neoadjuvant Regimens in Subtypes of Breast Cancer

November 24, 2014 updated by: Binghe Xu, Cancer Institute and Hospital, Chinese Academy of Medical Sciences

Phase 2 Randomized Study of Different Neoadjuvant Regimens in Subtypes of Breast Cancer

There are no standard neodjuvant regimens adapted according to the different subtypes of breast cancer. This is a phase 2, randomized study to evaluate several regimens in different subtypes of breast cancer.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Breast cancer is a heterogenous disease with at least 4 intrinsic subtypes including Luminal A, Luminal B, HER2 enriched, Basal-like and normal breast like. Different subtypes have different prognosis and treatment sensitivity. Thus, it would be more suitable to administer different chemo-regimen in different subtypes. This is especially true in neoadjuvant chemotherapy setting where no standard regimen has ever been established. Therefore, we designed this phase 2 randomized clinical trial to explore potential effective regimens in variable subtypes of breast cancer in neoadjuvant treatment. Patients were first classified into Luminal type, Her2 positive type and triple-negative type by immunohistochemistry exam of ER/PR/HER2 in core needle biopsy and then randomized to received either dose dense paclitaxel in Luminal type or dose dense paclitaxel plus carboplatin with or without trastuzumab in HER2 positive type or dose dense paclitaxel plus carboplatin in triple-negative type.The control groups in each subtype all receive paclitaxel plus epirubicin every 3 weeks. The duration of treatment is 4-6 cycles. Primary endpoint is the pathological CR rate in each subtypes. Secondary endpoints include disease free survival, objective response rate, safety. Tissue samples and blood samples will be collected at baseline and during treatment. There will be exploratory biomarkers analyses to identify predictive markers for efficacy in every subtypes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
pathological complete response(pCR) rate of breast and axilla after surgery
Time Frame: 3 years
pathological complete response(pCR) of breast and axilla after surgery means after operation, no invasive component can be found in both breast and axillary lymph nodes. The pCR rate is calculated by number of patients having pCR after sugery divided by number of patients receiving neoadjuvant chemotherapy.
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Disease free survival
Time Frame: 3years and 5years after operation
3years and 5years after operation
Overall survival
Time Frame: 3 years and 5years after operation
3 years and 5years after operation
Adverse event
Time Frame: during screening and treatment, withing 21 days after day 1 of last cycle
during screening and treatment, withing 21 days after day 1 of last cycle
