Study summary

Eligible patients with stage 2 and 3 triple negative breast cancer will be treated with 4 cycles of neoadjuvant paclitaxel/carboplatin/pembrolizumab. A PET scan will be performed at baseline and after 1 cycle of therapy. A breast MRI will be performed after treatment completion. Patients with complete clinical response will proceed to surgery. Patients with clinical residual disease will complete neoadjuvant rescue with 4 cycles of doxorubicin/cyclophosphamide prior to surgery. If residual disease identified after surgery, adjuvant therapy to be determined by the treating oncologist (may include doxorubicin/cyclophosphamide/pembrolizumab, capecitabine etc).

Read the detailed description

Eligible participants will undergo baseline procedures including research bloodwork, MRI and PET scan. Participants will then be treated with one cycle of paclitaxel, carboplatin and pembrolizumab (TCarbo/pembro). At the end of Cycle one patients will undergo repeat procedures (bloodwork and PET scan), and then continue with treatment for an additional three cycles. ctDNA will be collected on day 1 of each cycle. At the end of treatment patients will undergo repeat MRI.

Patients achieving a clinical complete response (CR) on MRI will proceed with surgery. Patients with clinical residual disease (RD) on MRI will be recommended a biopsy, and be recommended "rescue" neoadjuvant doxorubicin and cyclophosphamide with pembrolizumab (AC/pembro) for four additional cycles, and then proceed with surgery. Note: patients/treating physician may opt to proceed with surgery.

Archival tissue will be collected from the surgical product. Patients achieving a pathologic CR (pCR) may proceed with adjuvant pembrolizumab per standard of care, and treating physician's discretion. Patients with pathological RD may proceed with "rescue" adjuvant AC/pembrolizumab for four additional cycles (if not given neoadjuvantly), per treating physician discretion. The participants may also receive Aadjuvant capecitabine or olaparib as indicated and per treating physician's discretion.

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.

Inclusion criteria

  1. Stage II-III TNBC - estrogen receptor (ER) and progesterone receptor (PR) up to and including 10% is eligible
  2. Age ≥ 18 years
  3. (ECOG) performance status of 0 to 2
  4. Eligible for standard chemo-immunotherapy as determined by treating physician, including consideration of:

    1. Adequate marrow and organ function
    2. Co-morbid conditions do not preclude the use of chemo-immunotherapy (such as uncontrolled disease, or the use of medications)
  5. Patients must have the ability to understand and the willingness to sign a written prior to registration on study

Exclusion criteria

Exclusion Criteria:

  1. Patients unable to undergo PET or MRI
  2. Evidence of disease or loco-regional recurrence (i.e. distant or chest wall recurrence)
  3. Inflammatory breast cancer
  4. Previous treatment with paclitaxel, carboplatin, or
Terms in these criteria, in plain language(6)

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.

ECOG performance status

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.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Immunosuppression

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.

Informed consent

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.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

PD-1, PD-L1 and checkpoint inhibitors

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.

What researchers measure

Primary outcomes

  1. SULmax in relation to pCR

    Evaluate if lack of decrease in fluorodeooxyglucose (FDG) / positron emission tomography (PET) standardized uptake value corrected for lean body mass (SULmax) by \<40% after 1 cycle of neoadjuvant therapy correlates with residual disease at the time of surgery.

    Time frame: 8 months

Secondary outcomes

  1. Pathologic complete response (pCR)

    Evaluate the pathologic complete response (pCR) rate in patients with early-stage triple negative breast cancer (TNBC) treated with neoadjuvant chemo-immunotherapy.

    Time frame: 3 years

  2. Circulating tumor deoxyribonucleic acid (ctDNA) clearance

    Evaluate how circulating tumor deoxyribonucleic acid (ctDNA) kinetics collected at pre-treatment, and during and after completion of neoadjuvant treatment correlate with pathologic complete response (pCR) at the time of surgery.

    Time frame: 3 years

Other outcomes

  1. Pathologic complete response (pCR) comparison

    Compare the pathologic complete response (pCR) rates among patients who achieved clinical complete response (cCR) by breast magnetic resonance imaging (MRI) and those received "rescue" neoadjuvant AC/pembrolizumab with clinical residual disease (RD) after MRI scan.

    Time frame: 3 years

  2. Diagnostic accuracy of percent and absolute change between baseline and C1D15 measurements

    Evaluate the diagnostic accuracy of percent and absolute change (between baseline and C1D15 measurements), and C1D15 absolute measurements in fluorodeooxyglucose (FDG) / positron emission tomography (PET) standardized uptake value corrected for lean body mass (SULmax) for predicting clinical complete response (cCR) using receiver operating characteristic (ROC) curve.

    Time frame: 3 years

  3. Clinical complete response (cCR) and pathologic complete response (pCR)

    Investigate if clinical complete response (cCR) by MRI is predictive of pathologic complete response (pCR).

    Time frame: 3 years

  4. Change in microbiome

    Number of patients that experienced changes in the microbiome serially over time of residual disease.

    Time frame: 3 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2024 (actual). Primary completion is estimated for Jun 2029, 61 months after the start.

Of 220 non-industry phase 2 interventional studies under Triple Negative Breast Neoplasms, half reached primary completion within 60 months of starting (the median), counting those still running; a quarter within 38 and three quarters within 99. This study's planned 61 months is close to that.

Counting every sponsor, half of 255 studies reached it within 59 months; a quarter within 37 and three quarters within 94.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 3, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
