This phase II trial tests reduced post surgery (adjuvant) therapy for patients with early breast cancer who have confirmed that the disease has responded completely (pathologic complete response) after pre surgical treatment (neoadjuvant) therapy and do not have any tumor genetic material (molecular residual disease) circulating in their blood. Standard of care treatment after surgery consists of 1 year of pembrolizumab for patients with triple negative breast cancer or trastuzumab with or without pertuzumab to complete 1 year of treatment. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pertuzumab and trastuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When pertuzumab or trastuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Lowering the total amount of cancer therapy after breast surgery, may continue to keep the great tumor response to treatment, and may help lower the amount of side effects patients have.
PRIMARY OBJECTIVES:
I. To determine the 3-year event free survival (EFS) after breast surgery in patients with early triple negative breast cancer (TNBC) that achieve a pathologic complete response (pCR) after neoadjuvant systemic therapy (NST) with a pembrolizumab plus chemotherapy-based regimen and are minimal residual disease (MRD)-negative (negative circulating tumor deoxyribonucleic acid [ctDNA] with the NeXT Personal™ assay) at 4-6 weeks after breast surgery and discontinue standard of care (SOC) adjuvant pembrolizumab.
II. To determine the 3-year EFS after breast surgery in patients with early HER2+ breast cancer that achieve a pCR after NST with a trastuzumab and pertuzumab plus chemotherapy-based regimen and are MRD-negative (negative ctDNA with the NeXT Personal™ assay) at 4-6 weeks after breast surgery and discontinue SOC adjuvant trastuzumab and pertuzumab.
SECONDARY OBJECTIVES:
I. To estimate the rate of conversion from negative to positive ctDNA and time to conversion from negative to positive ctDNA among patients who undergo de-escalation of SOC adjuvant systemic therapy.
II. To establish the prevalence of patients with early TNBC or early HER2+ breast cancer who achieve a pCR after receiving NST and have a positive ctDNA with the NeXT Personal™ assay at 4-6 weeks after breast surgery.
III. To determine the 3-year EFS after breast surgery in patients with early HER2+ breast cancer or early TNBC that achieve a pCR after NST and have a positive ctDNA with the NeXT Personal™ assay at 4-6 weeks after breast surgery.
OUTLINE: Patients with triple negative breast cancer are assigned to cohort 1, patients with HER2 positive breast cancer are assigned to cohort 2.
COHORT 1: Patients may receive 1 to 3 cycles of standard of care treatment with pembrolizumab. Patients with a positive ctDNA test 4-6 weeks after surgery continue to receive standard of care treatment per their treating physician in the absence of disease progression or unacceptable toxicity. Patients with a negative ctDNA test will not receive further treatment with pembrolizumab and will undergo monitoring with ctDNA tests every 3 months for 3 years in the absence of disease progression.
COHORT 2: Patients may receive 1 to 3 cycles of standard of care treatment with trastuzumab with or without pertuzumab. Patients with a positive ctDNA test 4-6 weeks after surgery continue to receive standard of care treatment per their treating physician in the absence of disease progression or unacceptable toxicity. Patients with a negative ctDNA test will not receive further treatment with pembrolizumab and will undergo monitoring with ctDNA tests every 3 months for 3 years in the absence of disease progression. Patients may receive standard of care endocrine therapy per their treating physician throughout the study.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
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.
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 biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
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.
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.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
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 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.
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).
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.
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.
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.

Started Oct 2025 (actual). Primary completion is estimated for Sep 2028, 35 months after the start.
Of 1,070 non-industry phase 2 interventional studies under Breast Neoplasms, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 34 and three quarters within 87. This study's planned 35 months is below that.
Counting every sponsor, half of 1,302 studies reached it within 51 months; a quarter within 30 and three quarters within 82.
How these figures are worked out, and which studies are left out of them.
