BUFFALO, N.Y., Dec. 19, 2011 /PRNewswire/ -- Kinex Pharmaceuticals, LLC and Hanmi Pharmaceutical Co., Ltd. announced today the execution of a license agreement from Hanmi Pharmaceuticals granting Kinex Pharmaceuticals exclusive rights to their Orascovery technology (which includes a non-absorbed compound that facilitates the absorption of compounds that are usually not orally bioavailable or absorbed) and their current lead products including an oral formulation of paclitaxel, which is already in Phase II clinical trials in Korea, and an oral formulation of irinotecan, which has just completed Phase I clinical trials in Korea.
The Orascovery program is one of the key platforms developed by Hanmi Pharmaceuticals. HM30181A is a P-glycoprotein pump inhibitor, (known for its effect in pumping drugs back to the gastrointestinal tract and thereby reducing drug absorption) which inhibits the pumping action of this protein and therefore, serves as an oral absorption enhancer. This compound is very potent and is largely not absorbed and therefore, exerts its effect mainly in the gastrointestinal tract.
In preclinical studies, it has been shown that the administration of this absorption enhancer together with paclitaxel enhances the oral bioavailability of paclitaxel from 1% to >40%. For irinotecan and topotecan, the oral bioavailabilities were shown to be enhanced from 8% and 11% to >40% and >50%, respectively. The composition of matter of HM30181A is covered by issued patents.
The acquisition of an oral formulation of paclitaxel is important to both Kinex and Hanmi Pharmaceuticals as the taxanes have been shown to exhibit a strong synergistic effect with KX01, an orally bioavailable dual src kinase/pretubulin inhibitor that Kinex Pharmaceuticals and Hanmi Pharmaceuticals have been collaborating to develop since April 2011.
Under the terms of the agreement, Kinex Pharmaceuticals will acquire the rights to the development and co
