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.
In early breast cancer (eBC), pathological complete response (pCR) after neoadjuvant therapy acts as surrogate marker for metastasis and overall survival.

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.).

Eligible patients are identified considering pCR-status and clinical stage estrogen receptor status grade (CPS-EG)-score following surgery after neoadjuvant therapy.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
