About
In early breast cancer (eBC), pathological complete response (pCR) after neoadjuvant therapy acts as surrogate marker for metastasis and overall survival. Therapy intensification by adding an adjuvant therapy line (post-neoadjuvant treatment) substantially lowers the risk of relapse in high-risk breast cancer patients with residual disease after neoadjuvant treatment (non-pCR). While this approach was exemplified in two phase III trials without biomarker-stratification (CREATE-X, KATHERINE), even higher efficiency might be achieved by individualized genomic-guided post-neoadjuvant therapies.
Within the seven-arm umbrella phase-II clinical trial COGNITION-GUIDE, we aim to deliver molecularly-tailored cancer care by implementing an additional response- and genomics-guided post-neoadjuvant therapy after finishing the guideline-compliant post-neoadjuvant treatment in high-risk breast cancer patients with residual cancer burden after neoadjuvant therapy to reduce the substantial risk of local and distant relapse.
The trial evaluates not a single drug but rather a general strategy of precision oncology in the curative setting and provides the basis for future confirmatory biomarker-driven trials.
Allocation to the therapy-arms is conducted by in depth molecular characterization of tumors within the COGNITION registry program.
The study aims to show an overall benefit of the precision medicine approach in high-risk eBC patients and to allow for secondary exploratory evaluation of each study-arm.
The primary endpoint of the study is invasive Disease-Free Survival (IDFS) after 4 years measured from surgery to local or distant relapse or death. The sample size of the entire trial is 240 eligible patients.
Full description
In early breast cancer (eBC), pathological complete response (pCR) after neoadjuvant therapy acts as surrogate marker for metastasis and overall survival.
Therapy intensification by adding an adjuvant therapy line (post-neoadjuvant treatment) substantially lowers the risk of relapse in high-risk breast cancer patients with residual disease after neoadjuvant treatment (non-pCR).
While this approach was exemplified in two phase III trials without biomarker-stratification (CREATE-X, KATHERINE), even higher efficiency might be achieved by individualized genomic-guided post-neoadjuvant therapies.
To date, prospective whole genomic and transcriptomic sequencing in the framework of precision oncology concepts is predominantly conducted in advanced-stage cancer, limiting the overall benefit mainly to prolongation of progression-free survival rather than cure.
In contrast, the implementation of precision oncology in an early disease stage may empower targeted intervention based on high throughput sequencing at a time point with low tumor burden and limited clonal complexity, harbouring the prospect to substantially improve cure rates by prohibition of incurable metastasis.
Whole-genome (WGS), whole exome (WES), gene panel and transcriptome sequencing in the molecular diagnostic registry platform COGNITION (neoadjuvant-treated eBC patients) revealed relevant diagnostic information on molecular-druggable alterations in a substantial proportion of patients in different molecular pathways (e.g. phosphatidylinositol 3-kinase (PI3K)/ serine/threonine kinase (AKT), Mitogen-activated protein kinase (MAPK), apoptosis, DNA-repair, immune escape etc.).
Within the seven-arm umbrella phase-II clinical trial COGNITION-GUIDE, we aim to deliver molecularly-tailored cancer care by implementing an additional response- and genomics-guided post-neoadjuvant therapy after finishing the guideline-compliant post-neoadjuvant treatment in high-risk breast cancer patients with residual cancer burden after neoadjuvant therapy to reduce the substantial risk of local and distant relapse.
The trial evaluates not a single drug but rather a general strategy of precision oncology in the curative setting and provides the basis for future confirmatory biomarker-driven trials.
Eligible patients are identified considering pCR-status and clinical stage estrogen receptor status grade (CPS-EG)-score following surgery after neoadjuvant therapy.
Allocation to the therapy-arms is conducted by in depth molecular characterization of tumors within the COGNITION registry program.
Recruitment of adequate patient numbers in well-defined molecular subgroups is achieved in a multicenter approach.
The study aims to show an overall benefit of the precision medicine approach in high-risk eBC patients and to allow for secondary exploratory evaluation of each study-arm.
The primary endpoint of the study is invasive Disease-Free Survival (IDFS) after 4 years measured from surgery to local or distant relapse or death.
The sample size of the entire trial is 240 eligible patients.

Ages
Volunteers
Inclusion criteria
Provision of written informed consent
Female and male patients with non-metastatic early (stage I-III) breast cancer aged ≥ 18 years
Conducted neoadjuvant chemotherapy and surgery as well as conducted standard post-neoadjuvant treatment +/- radiotherapy (standard according to German guidelines except Abemaciclib and Olaparib)
For patients with initially triple negative (TNBC) or HER2-positive breast cancer:
• Non-pCR defined as other than ypT0/is ypN0
For patients with initially hormone receptor positive and HER2-negative breast cancer: Non-pCR and CPS-EG score
ECOG Performance Status ≤ 1
Acute effects of any prior therapy resolved to baseline severity or National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 (NCI CTCAE v5.0) Grade ≤ 1 except for adverse effects not constituting a safety risk by investigator judgement
Postmenopausal or evidence of non-childbearing status. For women of childbearing potential negative urine pregnancy test at post-operative screening and baseline as well as highly effective forms of contraception have to be in place thereafter
Evidence of childbearing potential is defined as fertile, following menarche and until becoming post-menopausal unless permanently sterile
Postmenopausal or evidence of non-childbearing status is defined as:
A man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy
Female patients of childbearing potential and male patients with partners of childbearing potential who are sexually active must agree to the use of two forms of contraception in combination (male condom and one highly effective method). These should be started immediately after signing the informed consent form and continued throughout the period of study treatment plus a substance-depending time period (see respective sub-protocol) for female patients and a substance-depending time period for male patients. Details on contraception and pregnancy testing for male and female patients (and if indicated their partners) under IMP treatment are described within the respective sub-protocol
Ability of patient to understand and comply with the protocol for the duration of the study, including treatment and scheduled visits and examinations
Adequate bone marrow, renal, and hepatic function defined by laboratory tests*
The biomarker-guided eligibility for the respective study arm is evaluated and determined exclusively by the NCT molecular tumor board on the basis of results of the COGNITION molecular diagnostic registry platform. Biomarkers that allow inclusion in the respective arm are:
