A Study of Abemaciclib (LY2835219) in Participants With Non-Small Cell Lung Cancer or Breast Cancer

Trial Status: Closed to Accrual

The main purpose of this study is to evaluate the safety and efficacy of abemaciclib in combination with pembrolizumab in participants with advanced non-small cell lung cancer (NSCLC) or hormone receptor positive (HR+), human epidermal growth factor receptor negative (HER2-) breast cancer.

Inclusion Criteria

  • Have a Stage IV diagnosis of 1 of the following: Part A: NSCLC (Kirsten rat sarcoma mutant [KRAS mt], PD-L1+); Part B: NSCLC (squamous histology); Part C: metastatic breast cancer (HR+, HER2-); or Part D: locally advanced or metastatic breast cancer (HR+, HER2-)
  • Part A: must be chemotherapy naïve for metastatic NSCLC
  • Part B: must have received at least 1 prior therapy containing platinum-based chemotherapy for advanced/metastatic NSCLC
  • Part C: must have previously received prior treatment with at least 1 but no more than 2 chemotherapy regimens in the metastatic setting
  • Part D: cannot have received endocrine therapy or chemotherapy as treatment in the locoregionally recurrent or metastatic breast cancer disease setting. Note: Participants may be enrolled if they received prior (neo)adjuvant chemotherapy or endocrine therapy for localized disease.
  • Are amenable to provide tumor tissue prior to treatment and provide tumor tissue after treatment initiation (both mandatory).
  • Have presence of measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST 1.1).
  • Have a performance status (PS) ≤1 on the Eastern Cooperative Oncology Group (ECOG) scale.
  • Have discontinued all previous treatments for cancer and recovered from the acute effects of therapy.
  • Have an estimated life expectancy of ≥12 weeks.
  • For Part D: Have postmenopausal status due to surgical/natural menopause or chemical ovarian suppression (initiated 28 days prior to Day 1 of Cycle 1) with a gonadotropin-releasing hormone (GnRH) agonist such as goserelin or radiation-induced ovarian suppression.

Exclusion Criteria

  • Have a personal history of any of the following conditions: syncope of either unexplained or cardiovascular etiology, ventricular arrhythmia (including but not limited to ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest. Exception: subjects with controlled atrial fibrillation for >30 days prior to study treatment are eligible.
  • Have central nervous system (CNS) metastasis with development of associated neurological changes 14 days prior to receiving study drug.
  • Have corrected QT interval of >470 milliseconds on screening electrocardiogram (ECG).
  • Have history of interstitial lung disease or pneumonitis.
  • Have history of or active autoimmune disease, or other syndrome that requires systemic steroids or autoimmune agents for the past 2 years.
  • Have received a live vaccination within 30 days of study start.
  • Have received prior treatment with an anti PD-1, anti-programmed death ligand 1 (PD-L1), or anti cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) agent.
  • For Part D Only:
  • Have initiated bisphosphonates or approved RANK ligand (RANK-L) targeted agents (for example, denosumab) <7 days prior to Cycle 1 Day 1.
  • Are currently receiving or have previously received endocrine therapy for locoregionally recurrent or metastatic breast cancer. Note: A participant may be enrolled if she received prior (neo)adjuvant endocrine therapy (including, but not limited to anti-estrogens or aromatase inhibitors) for localized disease.
  • Are currently receiving or have previously received chemotherapy for locoregionally recurrent or metastatic breast cancer. Note: Participants may be enrolled if they received prior (neo)adjuvant chemotherapy for localized disease.
