ICS-283 was developed within Intradigm Corporation as a system that is
designed for the systemic delivery of therapeutic small interfering (siRNA) to
sites of pathological angiogenesis. The non-viral siRNA delivery system is based
on synthetic nanoparticles, known as TargeTran™ (Intradigm Corporation),
which functions as a broad-platform technology to deliver siRNA to specific
target cells in diseased tissues. The system is constructed to incorporate different
functionalities that address critical needs for successful nucleic acid delivery.
The TargeTran synthetic vector is a self-assembling, layered nanoparticle
that protects and targets siRNA to specific cell types in pathological tissues. At
present, ICS-283 is the only antiangiogenic siRNA delivery system that is
designed for intravenous administration to treat angiogenesis-driven diseases
