Purpose: The purpose of this study is to find a recommended dose level and schedule of dosing LY3023414 that can safely be taken by participants with advanced or metastatic cancer, including but not limited to lymphoma, breast cancer, and mesothelioma. The study will also explore the changes to various markers in blood cells and potentially tumor cells. Finally, the study will help document any antitumor activity this drug may have.
In Part A of this study, participants with advanced/metastatic cancer (including lymphoma) will receive increasing doses of LY3023414. In Part B, LY3023414 will be explored in different types of cancer, including breast cancer and mesothelioma.
- Experimental Arm: Part A: LY3023414 Once Daily
- LY3023414 administered orally once daily (QD) at escalating doses for two 21 day cycles to participants with advanced/metastatic cancer (including lymphoma); participants receiving benefit may continue until disease progression or discontinuation.

- Drug: LY3023414
Administered orally QD or BID for a 21 day Cycle. Dose of 20 to 600 mg, as determined in Part A.
- Experimental Arm: Part A2: LY3023414 Twice Daily
- LY3023414 administered orally twice daily (BID) at escalating doses for two 21 day cycles to participants with advanced/metastatic cancer (including lymphoma); participants receiving benefit may continue until disease progression or discontinuation.
- Assigned Interventions:
- Drug: LY3023414
Administered orally QD or BID for a 21 day Cycle. Dose of 20 to 600 mg, as determined in Part A.
- Experimental Arm: Part B1 : LY3023414 + Midazolam
- LY3023414 administered orally QD or BID for two 21 day cycles to participants with advanced/metastatic cancer; participants receiving benefit may continue until disease progression or discontinuation. Dose based on Part A. 0.2 mg midazolam administered orally once before LY3023414 on Day 1 and once after LY3023414 on Day 15.
