The purpose of this first in human study is to find a safe dose level of the investigational drug REGN3767 alone or in combination with REGN2810. Other purposes of this study are to measure the levels of REGN3767 and REGN2810 in the subject's blood and to collect any evidence of tumor shrinkage when given alone or in combination with REGN2810.
REGN3767 and REGN2810 are both a type of drug called a monoclonal antibody. Antibodies are proteins that are naturally found in your blood stream that fight infections. A monoclonal antibody is a special kind of antibody that is manufactured as a medication to target a specific protein in the body that may be involved in the subject's cancer.
In this part of the study each participant will receive 1 of 3 different doses of REGN3767 alone or in combination with one dose of REGN2810. There will be a total of 6 different groups of participants the study team plans to study based on what dose of REGN3767 they receive and whether they receive it alone or with REGN2810.
The study is sponsored by Regeneron. The investigator in charge of this study at MUSC is Carolyn Britten, MD. Part 1 of this study is being done at 4-5 sites. Approximately24-48 people will take part study-wide.
