A Phase 1 Study of the CDK4/6 Inhibitor Ribociclib (LEE011) in Combination With the PD-1 Inhibitor PDR001 in Patients With Metastatic Hormone Receptor-positive Breast Cancer and Metastatic Ovarian Cancer

This clinical trial is studying the drug Ribociclib (LEE011) in combination with an
immunotherapy drug called PDR001 (a therapy that uses the body's own immune system to control
cancer) as a possible treatment for metastatic hormone-receptor-positive (HR+), HER2-negative
breast cancer (in combination with fulvestrant) or metastatic epithelial ovarian cancer.

The names of the medications involved in this study are:

- Ribociclib (LEE011)

- PDR001

- Fulvestrant

- This research study is a Phase I clinical trial, which tests the safety of an
investigational combination of drugs (LEE011 with PDR001), and tries to define the
appropriate dose of the above combination of investigational drugs to use for further
studies. "Investigational" means that the intervention is being studied.

- The FDA (the U.S. Food and Drug Administration) has approved LEE011 as a treatment for
hormone receptor positive metastatic breast cancer.

- The FDA has not approved PDR001 as treatment for any type of cancer.

- The FDA has approved fulvestrant as a treatment for hormone receptor positive metastatic
breast cancer.

- When given separately these medications work in different ways to try and stop cancer
cells from growing and spreading.

- LEE011 is a drug designed to block certain proteins called cyclin-dependent kinases
(CDKs) that are required for cells to divide. These proteins may also control the
ability of certain cancers to grow.

- PDR001 is an antibody. Antibodies are proteins usually produced by the body that
help protect against foreign matter, such as bacteria and viruses. PDR001 blocks a
protein called PD-1 which is present on cells called T-lymphocytes, which are
involved in the immune response. PDR001 is being tested to see if it will allow the
body's immune system to work against tumor cells. Other studies have shown that
blocking PD-1 may result in reduced tumor cell growth in a variety of solid tumors.

- Fulvestrant is an estrogen receptor antagonist that is indicated for the treatment
of postmenopausal women with HR+ MBC.

- In this research study, the investigators are looking for a safe and tolerable dose of
LEE011 that can be given in combination with PDR001 for participants with metastatic
hormone-receptor-positive (HR+), HER2-negative breast cancer (in combination with
fulvestrant) or metastatic epithelial ovarian cancer.
