Jet injection of a monoclonal antibody: A preliminary study.

ABSTRACT

Monoclonal antibodies (mAbs) represent a major group of biotherapeutics. The high concentration and volume of drug administered together with a shift to administration via the subcutaneous route have generated interest in alternative delivery technologies. The feasibility of using a novel, highly controllable jet injection technology to deliver a mAb is presented. The effect of delivery parameters on protein structure were evaluated and compared with delivery using a conventional needle and syringe. Injection of mAb into a rat model showed that jet injection using the device resulted in more rapid absorption and longer duration of exposure.
