ATOP Trial: Adjuvant Ado-Trastuzumab Emtansine (T-DM1) for Older Patients With Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Breast Cancer

This phase II trial studies how well trastuzumab emtansine works in treating older patients
with human epidermal growth factor receptor 2 (HER2)-positive stage I-III breast cancer. HER2
is a protein found on the surface of cancer cells that helps them to grow and spread.
Trastuzumab emtansine may kill cancer cells by binding to HER2-positive on the surface of the
tumor cells and blocking their ability grow and spread.

PRIMARY OBJECTIVES:

I. Invasive disease-free survival (IDFS), defined as occurrence of any of the following:
ipsilateral invasive breast cancer recurrence, regional invasive breast cancer recurrence,
distant recurrence, death attributable to any cause, contralateral invasive breast cancer, or
second non-breast invasive cancer. Note: In-situ events are not included.

SECONDARY OBJECTIVES:

I. Overall survival (OS). II. Recurrence-free survival (RFS). III. Adverse events. IV.
Cardiac function/adverse events. V. Site of first recurrence.

TERTIARY OBJECTIVES:

I. The associations of adverse events and outcomes with each of the following will be
examined: geriatric assessment (GA), patient reported outcomes (Patient-Reported Outcomes
Version of the Common Terminology Criteria for Adverse Event [PRO-CTCAE]), quality of life
(QOL), and biomarkers of aging.

II. To determine whether clinician-reported CTCAEs are more accurate when PRO-CTCAE data are
shared with the patient and clinician.

III. Utilize a high-throughput mutation profiling system (Oncomap) to query a large panel of
cancer gene mutations in older patients with HER2-positive breast cancers.

OUTLINE:

Patients receive trastuzumab emtansine intravenously (IV) over 30-90 minutes on day 1.
Treatment repeats every 21 days for 17 courses in the absence of disease progression or
unacceptable toxicity.

After completion of study treatment, patients are followed up at 6-12 months and then yearly
for 4 years.

Inclusion Criteria:

- Confirmed HER2-positive disease by local pathology, defined as immunohistochemistry
(IHC) 3+ or amplification by fluorescent in situ hybridization (FISH) (HER2/chromosome
17 centromere [CEP17] ratio >= 2 or an average of >= 6 HER2 gene copies per nucleus)
AND confirmed by Central Pathology Review (Mayo Clinic Rochester) prior to patient
being registered to begin protocol therapy

- NOTE: ductal carcinoma in situ (DCIS) components should not be counted in the
determination of HER2 status

- Stage I-III breast cancer with the following criteria met:

- If node-negative or if node status unknown (because it was not assessed), tumor
must be > 5 mm (T1b) of any hormone receptor subtype (document estrogen
receptor/progesterone receptor [ER/PR] status: if some ER/PR staining is present,
ER and PR negative are defined as being positive in < 10% cells [per local
pathology read])

- If node-positive (N1-N3), T1mi, T1a, T1b, T1c, T2, or T3 tumors are eligible

- Definition of node-negative disease (when node status known): If the patient
has had a negative sentinel node biopsy and/or a negative axillary
dissection, then the patient is determined to be node-negative; axillary
nodes with single cells or tumor clusters =< 0.2 mm by either hematoxylin
and eosin (H&E) or IHC will be considered node-negative; any axillary lymph
node with tumor clusters between 0.02 and 0.2 cm is considered a
micrometastasis; patients with a micrometastasis are eligible; an axillary
dissection is not required to be performed in patients with a positive
sentinel node and management of the axilla will be left up to the treating
provider; in cases where the specific pathologic size of lymph node
involvement is subject to interpretation, the principal investigator will
make the final determination as to eligibility; in these special situations,
the investigator must document this approval in the patient medical record

- ER/PR determination assays performed by IHC methods according to the local institution
standard protocol

- Standard chemotherapy/trastuzumab declined by patient OR patient is deemed by
physician for any reason to not be a candidate for standard therapy (i.e. patient
and/or provider choose not to pursue standard trastuzumab-based chemotherapy regimen
because of concerns related to toxicity or patient preference)

- For patients with bilateral or multifocal/multicentric breast cancers, one of the
following criteria must be met to enroll: (1) each cancer individually meets criteria
for enrollment (only ONE tumor has to undergo central confirmation for HER2), OR (2)
at least one tumor meets eligibility (per tumor size/nodes/subtype outlined above) and
the other foci in the ipsilateral or contralateral breast are also HER2-positive but
are too small for enrollment (e.g., a patient is eligible if a cancer is T2N0 and
HER2-positive in one breast, but the contralateral breast has a T1b HER2+ cancer that
isn?t eligible on its own, OR, (3) at least one tumor meets eligibility and the other
foci in the ipsilateral or contralateral breast are HER2-negative and do not meet
criteria for adjuvant chemotherapy per provider discretion (e.g. if a patient has a
HER2-positive tumor meeting eligibility but also has a second, HER2-negative, small,
node-negative, ER+, low grade cancer present, she is still eligible for enrollment);
however, in the specific case that a second breast cancer is stage III and
HER2-negative, that patient is excluded (because the second cancer is high-risk and
likely will require non-HER2-directed therapy)

- All tumor removed by either a modified radical mastectomy or a segmental mastectomy
(lumpectomy)

- NOTE: management of axillary lymph nodes is up to the treating provider; however,
all surgical margins should be clear of invasive cancer or DCIS (i.e., no tumor
on ink); the local pathologist must document negative margins of resection in the
pathology report; if all other margins are clear, a positive posterior (deep)
margin is permitted, provided the surgeon documents that the excision was
performed down to the pectoral fascia and all tumor has been removed; likewise,
if all other margins are clear, a positive anterior (superficial; abutting skin)
margin is permitted provided the surgeon documents that all tumor has been
removed
