IG-001 - A Non-Biologic Nanoparticle Paclitaxel for the Treatment of Solid Tumors

nab-paclitaxel (Abraxane^®)—a Cremophor-free, albumin-bound, nanoparticle form of paclitaxel—though a breakthrough in paclitaxel formulation, has inherent problems associated with any biologics. IG-001 (Genexol-PM^®), a polymeric micellar formulation forms nanoparticles with paclitaxel containing a hydrophobic core and a hydrophilic shell and is being developed as the next generation nanoparticle paclitaxel. Its target indications are solid tumors including Breast, Lung, Ovarian, Bladder, Melanoma and Pancreatic cancers. Similar to nab-paclitaxel, due to its very fast dissolution in plasma, high tumor/plasma ratio, and dose-proportional PK, IG-001 is a superior alternative to Taxol^®. Moreover, despite a lack of serum albumin in its formulation, IG-001 takes full advantage of its ability to rapidly deliver paclitaxel to the targeted tissue via an albuminmediated transport, as previously described for nab-paclitaxel.
