SAN DIEGO, Sept. 10 /PRNewswire-FirstCall/ -- ADVENTRX Pharmaceuticals, Inc. (Amex: ANX) a biopharmaceutical research and development company focused on commercializing proprietary product candidates for the treatment of cancer and infectious diseases, announced today that it has received confirmation from the U.S. Food and Drug Administration (FDA) regarding its proposed 505(b)(2) New Drug Application (NDA) regulatory path for ANX-514 (docetaxel emulsion). The FDA has indicated that data from a single study of approximately 28 patients that demonstrates the bioequivalence of ANX-514 and docetaxel is sufficient to support filing an NDA. Docetaxel is an anti-cancer agent that is approved to treat breast, non-small cell lung, prostate, gastric and head and neck cancers, and is marketed under the brand name Taxotere(R). Annual sales of Taxotere in 2006 were approximately $2.2 billion.
"This guidance from the FDA is significant as conducting a single marketing-enabling trial provides us a clear and direct clinical path and substantially shortens the timelines for clinical development and submitting an NDA for ANX-514," said Evan M. Levine, chief executive officer of ADVENTRX. "Pending appropriate clearances, we look forward to starting the proposed bioequivalence trial later this year."
The Company currently plans to submit an investigational new drug (IND) application in the fourth quarter of 2007. The proposed clinical trial will compare the blood levels of docetaxel following a single dose of ANX-514 or Taxotere in patients with advanced cancers. In addition, the Company plans to analyze the safety of ANX-514.
ANX-514 Preclinical Results
Preclinical results have demonstrated equivalent pharmacokinetics between ANX-514 (docetaxel emulsion) and the FDA-approved version of docetaxel, marketed under the brand name Taxotere. ANX-514 administered intravenously did not cause hypersensitivity reactions, as opposed to acute hypersensitivity reactions that were observed following intravenous treatment with Taxotere. Antitumor activity of the two products in animal models was similar.
About ANX-514 (docetaxel emulsion)
ANX-514 is a novel nano-emulsion formulation of the chemotherapy drug docetaxel, which is marketed under the brand name Taxotere. 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 hypersensitivity 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 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. This regulatory pathway 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. Upon approval, a drug may be marketed only for the FDA-approved indications in the approved dosage forms. Further clinical trials are necessary to gain approval for the use of the product for any additional indications or dosage forms. In connection with a Section 505 (b)(2) NDA covering ANX-514, ADVENTRX must certify that all applicable Taxotere patents have expired prior to the manufacture, use or sale of ANX-514.
