ADVENTRX Grants Manufacturing Contract for ANX-514 (Docetaxel Emulsion)

SAN DIEGO, April 05, 2007 /PRNewswire-FirstCall/ -- ADVENTRX Pharmaceuticals, Inc., , a biopharmaceutical research and development company focused on commercializing proprietary product candidates for the treatment of cancer and infectious diseases, today announced that it has entered into an agreement with Hyaluron Contract Manufacturing to manufacture ANX-514 (docetaxel emulsion) for preclinical and clinical studies.

"We are excited about the on-going development of ANX-514," said Evan M. Levine, Chief Executive Officer of ADVENTRX. "ANX-514 fits well with our approach of developing less toxic drugs and improving patient care. We anticipate seeking guidance from the Food and Drug Administration with regard to a 505(b)(2) regulatory path for ANX-514, and pending appropriate clearances, initiating a marketing-enabling clinical trial of ANX-514 later this year."

ADVENTRX is conducting preclinical pharmacokinetic testing of ANX-514 to compare this product candidate with the approved version of the product, marketed under the brand name Taxotere(R). The Company currently plans to seek guidance from the FDA in 2007 with respect to the appropriateness of a Section 505(b)(2) NDA regulatory path for ANX-514.

About ANX-514 (docetaxel emulsion)

ANX-514 is a novel nano-emulsion formulation of the chemotherapy drug docetaxel, a product marketed under the brand name Taxotere. ANX-514 is designed to eliminate the need for multi-day immunosuppressant premedication. ANX-514 is formulated without polysorbate 80 or other detergents and is intended to reduce the severity and/or incidence of hypersensitivity reactions. Docetaxel is an anti-cancer agent that acts by disrupting the cellular microtubular network that is essential for cell division. Immunosuppressant premedication is recommended for docetaxel therapy to reduce the incidence and severity of allergic reactions. Docetaxel is approved to treat breast, non-small cell lung, prostate, gastric and head and neck cancers.

About Section 505(b)(2)

Section 505(b)(2) of the U.S. Food, Drug & Cosmetic Act (FDCA) allows the Food and Drug Administration (FDA) to approve a follow-on drug on the basis of data in the scientific literature or conclusions regarding safety or effectiveness made by the FDA in the approval of other drugs. Section 505(b)(2) of the FDCA was enacted as part of the Drug Price Competition and Patent Term Restoration Act of 1984, otherwise known as the Hatch-Waxman Act. This procedure potentially makes it easier for drug manufacturers to obtain rapid approval of new forms of drugs based on the FDA's approval of the original drug. Some examples of products that may be allowed to follow a 505(b)(2) path to approval are drugs that have a new dosage form, strength, route of administration, formulation or indication.
