Trial summary

This is a prospective examination of ribonucleic acid (RNA) extracted from tumor material of breast cancer patients treated with a neo-adjuvant therapy. The RNA will be analysed for expression of estrogen receptor (ER 1), progesterone receptor (PgR), HER2 and Ki-67 with MammaTyper™. Read more about this study

About this study

Official title: Evaluation of the MammaTyper Kit, Ref 90020/90021 Performed on Clinical Material Obtained From Patients With Early Breast Cancer: Re-Examination of Tumor Material and Re-Evaluation of Patient Data From Patients Treated With Neo-adjuvant Therapy

This is a prospective examination of ribonucleic acid (RNA) extracted from tumor material of breast cancer patients treated with a neo-adjuvant therapy. The RNA will be analysed for expression of estrogen receptor (ER 1), progesterone receptor (PgR), HER2 and Ki-67 with MammaTyper™.

According to the determined values for the individual parameters at least 4 subtypes can be distinguished to date

Read more
  • Luminal A-type
  • Luminal B-type
  • HER2-type
  • Triple-negative-type As non-clinical endpoint, the agreement of new subtyping with Immunohistochemical methods will be evaluated.

As clinical objective, the 5 year Distant metastasis free survival (DMFS) and Overall survival (OS) will be reevaluated according to the new subtyping.

Read the detailed description

Tumor material collected from patients who received neoadjuvant therapy either with four cycles of doxorubicin 60 mg/m² plus pemetrexed 500 mg/m² on day 1 every 21 days followed by four cycles of docetaxel 100 mg/m² on day 1 every 21 days or four cycles of doxorubicin 60 mg/m² plus cyclophosphamide 600 mg/m² on day 1 every 21 days followed by four cycles of docetaxel 100 mg/m² on day 1 every 21 days will be re-analyzed with the MammaTyper Kit. The Kit is an in-vitro molecular diagnostic test for molecular subtyping of breast cancers into Luminal A \& B, HER2 and Triple negative. It allows quantitative detection of the RNA expression status of the genes for estrogen receptor (ESR1), PgR, HER2 and Ki-67 on the basis of their mRNA present in the samples. This prospective diagnostic study will investigate the subtyping-results of the MammaTyper™ analysis and will compare them to the subtyping of the former immunohistochemical analysis performed. Based on the MammaTyper™-subtypes the efficiency of the therapy regimen and the outcome will be re-evaluated from the patient data.

What participants receive

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

  • MammaTyper™Device

    MammaTyper™ is an in vitro molecular diagnostic test for the quantitative detection of the biomarkers estrogen receptor (ESR1), progesterone receptor ( PgR), Human epidermal growth factor receptor 2 (HER2) and proliferation antigen Ki-67 on the basis of the values of the messenger ribonucleic acid (mRNA).

What is being measured

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

  1. Agreement of new subtyping assessed as rate of patients in MammaTyper-subtype groups compared to rate of patients in subtype groups according to immunohistochemical analysis according to St. Gallen Guideline 2013

    For each MammaTyper and immunohistochemical based subtype categorization, percent agreement, positive and negative percent agreement as well as kappa-statistics are calculated.

    Measured: Baseline

Secondary outcomes (3)
  1. Assess difference of 5 year OS of breast cancer subgroup Luminal A vs. combined subgroup (Luminal B (HER2 positive / HER2 negative), HER2 positive, triple negative), based on subtyping with MammaTyper™

    Assessed as rate of patients in subgroup Luminal A with 5 year OS vs. rate of patients in combined subgroups with 5 year OS based on MammaTyper subtyping

    Measured: 5 years from the date of patient registration

  2. Estimation of difference in prediction of pathologic complete remission for MammaTyperTM Ki-67 vs. local Ki-67 visual scoring assessment for Luminal tumors, whereby a positive difference is expected

    Assessed as rate of patients with complete response and Ki-67 determination according to MammaTyper and visual scoring assessment

    Measured: Baseline

  3. ESR1 mRNA is predictive for 5 year OS with low expression of ESR1 mRNA being associated with adverse outcome (rate of patients with 5 year OS and high or low expression of ESR1 mRNA)

    Assessed as rate of patients with 5 year OS and high or low expression of ESR1 mRNA

    Measured: 5 years from the date of patient registration

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by BioNTech Diagnostics GmbH.

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 2 inclusion and 4 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: finished, as of the sponsor's last update on 18 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Agreement of new subtyping assessed as rate of patients in MammaTyper-subtype groups compared to rate of patients in subtype groups according to immunohistochemical analysis according to St. Gallen Guideline 2013 (time frame: Baseline). 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 18 Jan 2017.
