Postmenopausal Women with Hormone Receptor Positive, HER2 Negative Breast Cancer

Objectives

The primary objective of Study I3Y-MC-JPBY (JPBY) is to compare the biological activity of abemaciclib in combination with anastrozole, abemaciclib monotherapy, and anastrozole monotherapy by assessing the percentage change from the baseline value in Ki67 expression after 2 weeks of therapy.

Test Drug

abemaciclib

Active Ingredient

LY2835219

Dosage Form

Capsule

Dosage

50

Endpoints

Criteria for Evaluation:
Efficacy:
• percent change in Ki67 expression from baseline to the core biopsy 2 weeks after the start of treatment
• pCR defined as absence of invasive cancer in the breast and sampled regional lymph nodes
• clinical response of the breast tumor to therapy as assessed by caliper measurement
• radiologic response of the breast tumor as assessed by radiologic or ultrasound assessment
Safety:
• adverse events
Health Outcomes:
• EORTC QLQ-C30
Pharmacokinetics:
• PK of abemaciclib and its metabolites and anastrozole
Pharmacodynamics:
• Ki67
Biomarkers:
• Whole blood, plasma, and tissue samples will be tested for biomarkers relevant to abemaciclib and the disease state and to correlate these markers to clinical outcomes.

Inclution Criteria

Inclusion Criteria:
• Have postmenopausal status.
• Adenocarcinoma of the breast.
• Breast tumor ≥1 centimeter (cm) in diameter, HR+, HER2-.
• Neoadjuvant endocrine monotherapy is deemed to be a suitable therapy.
• Primary breast cancer that is suitable for baseline core biopsy.
• Have adequate organ function.

Exclusion Criteria

Exclusion Criteria:
• Bilateral invasive breast cancer.
• Metastatic breast cancer (local spread to axillary lymph nodes is permitted).
• Inflammatory breast cancer.
• Prior systemic therapy or radiotherapy for invasive or non-invasive breast cancer in the same breast as currently being treated.
• Prior radiotherapy to the ipsilateral chest wall for any malignancy.
• Prior anti-estrogen therapy.
