Re-Evaluation of Tumor Samples From Women With Breast Cancer With the in Vitro Diagnostic Kit "MammaTyperTM"

September 16, 2016 updated by: BioNTech Diagnostics GmbH

Evaluation of the MammaTyperTM Kit, Ref 90020/90021 Performed on Clinical Material Obtained From Patients With Breast Cancer: Re-Examination of Tumor Material and Re-Evaluation of Patient Data of the FinHer-Study

This is a prospective examination of tumor material of breast cancer patients randomized into the FinHer-trial (= (= Comparison of vinorelbine and docetaxel and trastuzumab as adjuvant treatments of breast cancer patients wirh a high risk of cancer recurrence).

The formalin-fixed, paraffin-embedded tissue samples will be analysed for Estrogen receptor 1 (ESR1), progesterone receptor (PgR), Human epidermal growth factor receptor 2 (HER2) and Antigen Ki-67 (Ki-67) with the molecular in vitro diagnostic kit MammaTyper™.

According to the new subtyping the 5 year Distant disease free survival (DDFS) and Overall survival (OS) will be re-evaluated.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Despite the fact that reliable measures for the markers ESR1, PgR, HER2, Ki-67 are necessary with the currently used methods up to 20% of determinations are inaccurate and especially Ki67- measures are not very reproducible. Therefore new evaluation systems or new methods are necessary to improve diagnostic.

At least 4 subtypes can be distinguished to date depending on the expression of ESR, PgR, Her2 and Ki-67:

  • Luminal A-type
  • Luminal B-type
  • Her2-type
  • Triple-negative-type

MammaTyper™ uses a new approach. Instead of detection of the marker proteins, the messenger ribonucleic adic (mRNA) of marker proteins is quantitated. This prospectively planned diagnostic study will investigate the potential of subgrouping of patients at baseline according to results of MammaTyper™ methodology for predicting survival.

Patients will be subgrouped according to the new marker determination and the DDFS and OS will be evaluated and compared to the DDFS and OS of subgrouping with former marker determination.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

  • The patient provides a written informed consent for study participation
  • The estimated risk of breast cancer recurrence is high (25% or higher within the first 5 years from the date of the diagnosis, over >35% within the first 10 years from the diagnosis)

Exclusion Criteria:

  • Patients with breast cancer with "a special histological type" (mucinous, papillary, medullary, or tubular type of breast cancer) when no metastases are present in the ipsilateral axillary lymph nodes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: MammaTyper™
MammaTyper™ kit will be used tio assess tumor material of patients enrolled into the FinHer trial.
Device: MammaTyper™
MammaTyper™ kit is a molecular in vitro diagnostic test for the quantitative detection of the ribonuclease acid (RNA) expression status of the genes for estrogen receptor (ESR1), progesterone receptor (PGR), human epidermal growth factor receptor 2 (HER2) and proliferation antigen KI 67.

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
5 Year Distant Disease Free Survival (DDFS) Assessed as Rate of Patients Without Distant Metastases in Subgroup Luminal A vs. Combined Subgroup (Luminal B, HER2 Positive, Triple Negative), Based on Subtyping With MammaTyper™
Time Frame: 5 year from the date of patient randomisation
Tumor material of breast cancer patients will be newly assessed by MammaTyper™ and 5 year DDFS will be calculated new according to new subgrouping (Luminal A vs. combined subgroup (Luminal B, HER2 positive, triple negative))
5 year from the date of patient randomisation

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
Measure Description
Time Frame
Number of Patients With High Ki-67 and Prognosis on Outcome for DDFS and OS (Measured by Hazard Ratio)
Time Frame: 5 years
High Ki-67 is prognostic for worse outcome for DDFS and OS (measured by hazard ratio)
