CompassHER2-pCR: Decreasing Chemotherapy for Breast Cancer Patients After Pre-surgery Chemo and Targeted Therapy

NCT04266249

Description:

This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When these drugs attach to HER2 receptors, 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. Giving paclitaxel, trastuzumab, and pertuzumab may enable fewer chemotherapy drugs to be given without compromising patient outcomes compared to the usual treatment.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To determine if 3-year recurrence-free survival (RFS) is greater than 92% among clinical
      stages II or IIIa patients with HER2-positive breast cancer who achieve pathologic complete
      response (pCR) (ypT0/is ypN0) after preoperative therapy with 12 weeks of a taxane,
      trastuzumab (or Food and Drug Administration [FDA] approved biosimilar) and pertuzumab (THP x
      12).

      SECONDARY OBJECTIVES:

      I. To determine 3-year IDFS (invasive disease-free survival), DDFS (distant disease-free
      survival), DRFS (distant relapse-free survival), RFI (recurrence-free interval), OS (overall
      survival) and breast cancer-specific survival in patients who achieve pCR (and by
      pretreatment clinical stage). (Secondary Clinical Objective) II. To determine 3-year EFS
      (event-free survival) in all patients from time of study registration. (Secondary Clinical
      Objective) III. To evaluate safety and tolerability for all patients during the pre-operative
      phase and for patients who attain pCR and de-escalate therapy (Arm A) until the completion of
      post-surgery protocol assigned therapy (i.e. until the end of trastuzumab and pertuzumab [HP]
      therapy). (Secondary Clinical Objective) IV. To evaluate the association of estrogen receptor
      (ER) status in the untreated primary tumor with pathologic response and with long-term
      survival outcomes (including RFS, EFS, IDFS, DDFS, DRFS, RFI, OS, and breast cancer-specific
      survival). (Secondary Correlative Objective) V. To evaluate the associations of detection of
      circulating tumor cells (CTCs) in the blood at baseline with pCR. (Secondary Correlative
      Objective) VI. To evaluate the association of detection of CTCs in the blood at baseline,
      after 3 weeks of THP, after 12 weeks of THP (before surgery), after surgery before any
      additional therapy, and after completion of HER2-targeted therapy with RFS in patients who
      achieve pCR or not. (Secondary Correlative Objective)

      EXPLORATORY OBJECTIVES:

      I. To determine 3-year RFS, IDFS (invasive disease-free survival), DDFS (distant disease-free
      survival), DRFS (distant relapse-free survival), RFI (recurrence-free interval), OS (overall
      survival) and breast cancer-specific survival in patients who do not achieve pCR (and by
      pretreatment clinical stage). (Exploratory Clinical Objective) II. To determine the
      pathologic response to THP neoadjuvant therapy, as assessed by residual cancer burden (RCB).
      (Exploratory Clinical Objective) III. To determine the association between residual cancer
      burden (RCB) and all described standardized definitions for efficacy end points (STEEP)
      criteria outcomes. (Exploratory Clinical Objective) IV. To determine the false negative rate
      (FNR) of limited staging procedures (defined as sentinel lymph node biopsy [SLNB] plus
      removal of clipped node) in patients who undergo such procedures with a planned axillary
      lymph node dissection (ALND). (Exploratory Clinical Objective) V. To determine axillary pCR
      rates as a function of the burden of disease at presentation as determined on pre-treatment
      ultrasound (US) and the axillary staging technique (SLNB plus ensuring removal of clipped
      node versus ALND). (Exploratory Clinical Objective) VI. To evaluate the associations between
      plasma tumor cell-free deoxyribonucleic acid (DNA) (cfDNA) tumor-specific mutations (baseline
      and after therapy) with pathologic response and long-term outcomes (including RFS, EFS, IDFS,
      DDFS, DRFS, RFI, OS, and breast cancer-specific survival). (Exploratory Correlative
      Objective) VII. To evaluate the associations between tumor infiltrating lymphocytes (TILs)
      and immune activation gene signatures in the baseline tumor with pathologic response and
      long-term outcomes (including RFS, EFS, IDFS, DDFS, DRFS, RFI, OS and breast cancer-specific
      survival). (Exploratory Correlative Objective) VIII. To determine the frequency of change in
      intrinsic subtype between pretreatment tumor specimen and residual disease at the time of
      surgery. (Exploratory Correlative Objective) IX. To evaluate the associations between DNA
      copy number, DNA mutations, ribonucleic acid (RNA) expression and protein expression in the
      baseline tumor and changes from baseline to post-THP therapy with pathologic response and
      long-term outcomes (including RFS, EFS, IDFS, DDFS, DRFS, RFI, OS, and breast cancer-specific
      survival). (Exploratory Correlative Objective)
