Summary
Brief summary
The main purpose of this study is to:

- Learn about the safety of REGN4018 and to find out what dose of REGN4018 can be given
alone or with cemiplimab to patients with ovarian cancer or cancer of the uterus

- The study will also look at the levels of REGN4018 and/or cemiplimab in your body and
measure how well your body can remove the study drug(s). This is called pharmacokinetics

- The study will also look at any signs that REGN4018 alone or with cemiplimab can treat
recurrent advanced ovarian cancer or cancer of the uterus

- To find out how safe and tolerable the sarilumab pretreatment is, in combination with
REGN4018 and cemiplimab
