Brief description of study

What is this study about?
This phase III trial compares the effects of shorter chemotherapy (chemo)-immunotherapy without anthracyclines to usual chemo-immunotherapy for the treatment of early-stage triple negative breast cancer. Paclitaxel is in a class of medications called anti-microtubule agents. It stops cancer cells from growing and dividing and may kill them. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Docetaxel is in a class of medications called taxanes. It stops cancer cells from growing and dividing and may kill them. Doxorubicin is an anthracycline chemotherapy drug that damages DNA and may kill cancer cells. Pembrolizumab may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Shorter treatment without anthracycline chemotherapy may work the same as the usual anthracycline chemotherapy treatment for early-stage triple negative breast cancer.

THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study

What will happen during the study?
  • Patients are randomized to 1 of 2 arms.
  • ARM I: Patients receive paclitaxel intravenously (IV), carboplatin IV, and pembrolizumab IV on study. Patients then receive doxorubicin IV, cyclophosphamide IV, and pembrolizumab IV on study. Patients then undergo surgery. Patients may receive pembrolizumab after surgery. Patients may optionally undergo collection of blood samples throughout the trial.
  • ARM II: Patients receive docetaxel IV, carboplatin IV, and pembrolizumab IV on study. Patients then undergo surgery. Patients may receive pembrolizumab after surgery. Patients may optionally undergo collection of blood samples throughout the trial.
  • Patients are followed up every 6 months for the first 2 years and then annually until 5 years from registration.
