1Reported efficacy for KRISTINE is based on the 2019 update.

Chemotherapy

Targeted therapy

21-day cycle for 6 cycles

Subsequent treatment

  • TRYPHAENA: Surgery, then further adjuvant treatment (radiotherapy, chemotherapy, hormonal treatment) according to local guidelines (a total of 1 year of trastuzumab was given)

Miller-Payne scoring system

  • Grade 1: No change or some changes to individual malignant cells, but no reduction in overall cellularity
  • Grade 2: Minor loss of tumor cells (up to 30%), but overall cellularity still high
  • Grade 3: An estimated 30 to 90% reduction in the number of tumor cells
  • Grade 4: Marked disappearance of tumor cells such that only small clusters or widely dispersed individual cells remain (loss of greater than 90% of tumor cells)
  • Grade 5: No invasive cancer cells identifiable in sections from the site of the tumor (carcinoma in situ may be present)

Residual cancer burden (RCB)

  • The RCB is calculated as follows: RCB = 1.4 (finv*dprim)0.17 + [4(1 - 0.75LN)dmet]0.17
    • where dprim is derived from the bidimensional diameters of the primary tumor bed in the resected specimen, finv is the proportion of the primary tumor bed that contains invasive carcinoma, LN is the number of axillary lymph nodes containing metastatic carcinoma, and dmet is the diameter of the largest metastasis in an axillary lymph node.
    • The cut-off points are 1.36 and 3.28.

    • T-D: No therapeutic effect

Tumor response ratio

Calculated as follows: Residual breast disease observed upon pathologic examination divided by the size of the tumor on the pre-neoadjuvant therapy image.

  • TRR = 0: pathologic complete response (pCR)
  • TRR greater than 0 up to 0.4: strong partial response
  • TRR greater than 0.4 up to 1.0: weak partial response (WPR)
  • TRR greater than 1.0: tumor growth

Note: to our knowledge, this regimen was not tested as an experimental arm in an RCT in this context, prior to becoming a standard comparator arm. The protocol document reported a flat dose of oral cyclophosphamide, but this would not be consistent with any other known CMF variants; dosing below is provided as BSA-based.

Chemotherapy, CMF portion (cycles 1 to 6)

Targeted therapy, H portion (cycles 7 to 24)

21-day cycle for 24 cycles (CMF x 6; H x 18)

Median TTP: 6 vs 8.5 mo

Note: Esteva et al. 2002 described the day before the start of a cycle as "day 0," which is not the typical convention, so day -1 is being used instead.

Chemotherapy

Targeted therapy

  • Trastuzumab (Herceptin) given second as follows:
    • Cycle 1: 4 mg/kg IV over 90 minutes once on day -1, then 2 mg/kg IV over 30 minutes once per day on days 8 & 15
    • Cycle 2 onwards: 2 mg/kg IV over 30 minutes once per day on days 1, 8, 15

Supportive therapy

  • Dexamethasone (Decadron) 4 mg PO every 12 hours x 3 doses on cycles 1 & 2, starting the night prior to docetaxel. Patients who did not have "hypersensitivity reactions and no significant fluid retention during the first 8 weeks" received 4 mg PO twice per day on day 1 for at least the next two cycles. Patients who "remained free of fluid retention after 8 additional weeks" then received 4 mg PO once on day 1 prior to docetaxel in subsequent cycles.

1Reported efficacy for CLEOPATRA is based on the 2020 update.
Note: Dose of docetaxel in TDM4450g and MARIANNE was per investigator's discretion. CLEOPATRA has an unusual schedule with both medications being given on day 2 of cycle 1, due to this regimen being the control arm, in which patients in one arm received a placebo instead of pertuzumab on day 1. It is reasonable to assume that in practice, drugs in this regimen will be given on day 1 from the beginning.

Chemotherapy

Targeted therapy

21-day cycle for at least 6 cycles

Subsequent treatment

  • CLEOPATRA, if it is decided to no longer administer docetaxel with this regimen: patients could continue to receive trastuzumab maintenance

    • Cycles 2 to 8: 2 mg/kg IV over 30 minutes once per day on days 1, 8, 15

Supportive therapy

  • Dexamethasone (Decadron) 8 mg (or equivalent) PO twice per day x 6 doses, starting the night prior to docetaxel
  • "Antiemetic premedication was mandatory" (no additional details given).

21-day cycle for 6 cycles (M77001; see note) or 8 cycles (BCIRG 007)

Subsequent treatment

  • M77001: Patients could receive docetaxel beyond six cycles at the discretion of the investigator. Otherwise, patients proceeded to trastuzumab maintenance.

1Reported efficacy for CLEOPATRA is based on the 2020 update.
2Reported efficacy for PUFFIN is based on the 2022 update.

Chemotherapy

  • Docetaxel (Taxotere) given third as follows:
    • Cycle 1: 75 mg/m2 IV once on day 2
    • Cycle 2 onwards: 75 mg/m2 IV once on day 1

Targeted therapy

  • Trastuzumab (Herceptin) as follows:
    • Cycle 1: 8 mg/kg IV over 90 minutes once on day 2
    • Cycle 2 onwards: 6 mg/kg IV over 30 to 90 minutes once on day 1
  • Pertuzumab (Perjeta) as follows:
    • Cycle 1: 840 mg IV over 60 minutes once on day 1
    • Cycle 2 onwards: 420 mg IV over 30 to 60 minutes once on day 1

21-day cycle for at least 6 cycles

Subsequent treatment

  • CLEOPATRA, if it is decided to no longer administer docetaxel: patients could continue to receive pertuzumab & trastuzumab maintenance.
