MONARCH 2: A Randomized, Double-Blind, Placebo-Controlled, Phase 3 Study of Fulvestrant With or Without Abemaciclib, a CDK4/6 Inhibitor, for Women With Hormone Receptor Positive, HER2 Negative Locally Advanced or Metastatic Breast Cancer

The main purpose of this study is to compare progression-free survival for women with hormone
receptor positive (HR+), human epidermal growth factor receptor (HER2) negative advanced
breast cancer receiving either abemaciclib + fulvestrant or fulvestrant alone. Participants
will be randomized to abemaciclib or placebo in a 2:1 ratio. The study will last about 9
months for each participant.

For the endocrine naïve cohort, all participants will received abemaciclib + fulvestrant.


Inclusion Criteria

- Have a diagnosis of HR+, HER2- breast cancer

- Have locally advanced disease not amenable to curative treatment by surgery or
metastatic disease. In addition, participants must fulfill 1 of the following
criteria:

- relapsed with radiologic evidence of progression while receiving neoadjuvant or
adjuvant endocrine therapy, with no subsequent endocrine therapy received
following progression

- relapsed with radiologic evidence of progression within 1 year from completion of
adjuvant endocrine therapy, with no subsequent endocrine therapy received
following progression

- relapsed with radiologic evidence of progression more than 1 year from completion
of adjuvant endocrine therapy and then subsequently relapsed with radiologic
evidence of progression after receiving treatment with either an antiestrogen or
an aromatase inhibitor as first-line endocrine therapy for metastatic disease.
Participants may not have received more than 1 line of endocrine therapy or any
prior chemotherapy for metastatic disease

- presented de novo with metastatic disease and then relapsed with radiologic
evidence of progression after receiving treatment with either an antiestrogen or
an aromatase inhibitor as first line endocrine therapy for metastatic disease.
Participants may not have received more than 1 line of endocrine therapy or any
prior chemotherapy for metastatic disease

- for the endocrine naïve cohort: Must not have received prior endocrine therapy in
current or prior disease setting

- Have postmenopausal status due to either surgical/natural menopause or ovarian
suppression (initiated at least 28 days prior to Day 1 of Cycle 1) with a
gonadotropin-releasing hormone (GnRH) agonist such as goserelin

- Have a negative serum pregnancy test at baseline (within 14 days prior to
randomization) and agree to use medically approved precautions to prevent pregnancy
during the study and for 12 weeks following the last dose of abemaciclib if
postmenopausal status is due to ovarian suppression with a GnRH agonist

- Have either measurable disease or nonmeasurable bone only disease

- Have a performance status ≤1 on the ECOG scale

- Have discontinued previous therapies for cancer (including specifically, aromatase
inhibitors, anti-estrogens, chemotherapy, radiotherapy, and immunotherapy) for at
least 21 days for myelosuppressive agents or 14 days for nonmyelosuppressive agents
prior to receiving study drug, and recovered from the acute effects of therapy (until
the toxicity resolves to either baseline or at least Grade 1) except for residual
alopecia or peripheral neuropathy

Exclusion Criteria

- Are currently receiving an investigational drug in a clinical trial or participating
in any other type of medical research judged not to be scientifically or medically
compatible with this study

- Have visceral crisis, lymphangitic spread, or leptomeningeal carcinomatosis visceral
crisis is not the mere presence of visceral metastases but implies severe organ
dysfunction as assessed by symptoms and signs, laboratory studies, and rapid
progression of the disease

- Have clinical evidence or history of central nervous system metastasis

- Have received prior treatment with chemotherapy (except for neoadjuvant/ adjuvant
chemotherapy), fulvestrant, everolimus, or any CDK4/6 inhibitor. For the endocrine
naïve cohort: In addition, have received treatment with any prior endocrine therapy

- Have received treatment with a drug that has not received regulatory approval for any
indication within 14 or 21 days prior to randomization of study drug for a
nonmyelosuppressive or myelosuppressive agent, respectively

- Have received recent (within 28 days prior to randomization) yellow fever vaccination

- Have had major surgery within 14 days prior to randomization of study drug to allow
for post-operative healing of the surgical wound and site(s)

- Have a personal history within the last 12 months of any of the following conditions:
syncope of cardiovascular etiology, ventricular tachycardia, ventricular fibrillation,
or sudden cardiac arrest

- Have inflammatory breast cancer or a history of any other cancer (except nonmelanoma
skin cancer or carcinoma in-situ of the cervix), unless in complete remission with no
therapy for a minimum of 3 years

- Have received an autologous or allogeneic stem-cell transplant

- Have active bacterial or fungal infection, or detectable viral infection

- Have initiated bisphosphonates or approved Receptor activator of nuclear factor
kappa-B (RANK) ligand targeted agents <7 days prior to randomization
