Therapeutic Plasma Exchange Patients Cell Surface Proteins Plasmas
Rochester, MN
The purpose of this study is to determine if therapeutic plasma exchange (TPE) can reduce cell surface proteins circulating in plasma, including soluble receptors and extracellular vesicles (EVs).
Background:
Proteins expressed on the tumor surface are the focus of many targeted therapies, including antibody-based treatments, antibody-drug conjugates (ADCs), T cell receptor (TCR) fusion constructs, and chimeric antigen receptor T-cell (CAR-T) products. These target proteins can be shed from the tumor surface into the plasma as a soluble receptor or an EV, which may prevent targeted treatments from reaching the tumor. High levels of soluble MSLN (sMSLN) is associated with poor ...
