A Phase 1b Trial of LY2606368 in Combination With Chemotherapy or Targeted Agents in Advanced and/or Metastatic Tumors

The main purpose of this study is to investigate the safety of prexasertib in combination
with other anti-cancer drugs (cisplatin, cetuximab, pemetrexed, fluorouracil or LY3023414) in
participants with advanced cancer or cancer that has spread to another part of the body. The
study has multiple parts (A, B, C, D and E). Participants will only enroll in one part.

The primary purpose of Parts A, B, C, D and E of this study is to determine a recommended
dose level and schedule of prexasertib (an inhibitor of checkpoint kinase 1 and 2 [CHK1/CHK2]
in combination with:

- cisplatin (Part A)

- cetuximab (Part B)

- pemetrexed (Part C)

- fluorouracil (Part D)

- LY3023414 (Part E) [An inhibitor of phosphoinositide 3-kinase alpha (PI3K alpha) and
mammalian target of rapamycin (mTOR), DNA-dependent protein kinase (DNA-PK), and other
class I phosphoinositide 3-kinase (PI3K) family members]

in participants with advanced or metastatic cancer.

Part A dose expansion of the study will evaluate the safety and toxicity of prexasertib at
the recommended dose level in combination with cisplatin in participants with advanced or
metastatic cancer, Part B dose expansion of the study will evaluate the safety and toxicity
of prexasertib at the recommended dose level in combination with cetuximab in participants
with advanced or metastatic colorectal cancer, Part C and D dose expansions have been removed
and Part E dose expansion of the study will evaluate the safety and toxicity of prexasertib
at the recommended dose level in combination with LY3023414 in participants with advanced or
metastatic cancer, participants with PIK3CA mutations, or with advanced or metastatic breast
cancer.

In Parts A and B the effect of adding granulocyte colony stimulating factor (G-CSF) to
cisplatin in combination with prexasertib and cetuximab in combination with prexasertib will
be explored. In Part A the effect of changing the schedule of prexasertib and cisplatin also
will be explored. In Part B the effect of changing the schedule of prexasertib and cetuximab
also will be explored.
