FKBP12 dimerization domains in engineered immune cells

Description

Rimiducid is a small molecule dimerizing agent used as a safety switch in cellular immunotherapy protocols for colorectal cancer. It functions specifically to activate engineered safety mechanisms in CAR-T cells and CAR-NK cells that have been modified with inducible caspase-9 (iCasp9) systems. This medication serves as a critical safety control mechanism that can rapidly eliminate infused cellular therapies if severe adverse events occur during treatment.

Mechanism of Action

Rimiducid works by binding to and dimerizing the FK506-binding protein 12 (FKBP12) domains that are incorporated into modified caspase-9 proteins within engineered immune cells. Upon dimerization, the modified caspase-9 becomes activated and triggers apoptosis specifically in the infused CAR-T or CAR-NK cells. This provides clinicians with a pharmacological "off switch" to rapidly clear potentially harmful cellular therapies from the patient's system.
