ADVENTRX ANNOUNCES FURTHER COST-CUTTING MEASURES

• 55% Reduction in Staff Since Start of Q4 2008

• Evaluation of strategic alternatives on-going

• Executive VP Steps Down and Resumes Board Role

SAN DIEGO – January 5, 2009 – ADVENTRX Pharmaceuticals, Inc. (NYSE Alternext US: ANX) announced today that it has implemented a further reduction-in-force in an effort to extend its remaining cash and to prepare itself for a strategic transaction. This follows a reduction implemented in October 2008. In all, the Company’s workforce has declined by approximately 55% since the beginning of the fourth quarter of 2008. Following the current reduction and other planned departures, the Company will have fourteen employees. In addition, the Company has substantially reduced or delayed spending on third-party consulting and vendor services, including contract manufacturing.

ADVENTRX’s remaining employees will focus their efforts on continuing to evaluate strategic options, as well as continuing the Company’s on-going bioequivalence study of ANX-514 (docetaxel emulsion) and activities related to submitting a New Drug Application for ANX-530 (vinorelbine emulsion). The cost-cutting measures announced today should not have a direct and immediate effect on the Company’s previously announced timelines. However, any further cost-reductions or expense reductions/delays likely will have a negative impact the Company’s development and commercialization plans.

As part of its overall cost-cutting measures, Mark N. K. Bagnall, who in April 2008 joined the Company as Executive Vice President and Chief Financial Officer, agreed to return to his prior role as solely a member of the Company’s Board of Directors, and has agreed to provide consulting services on an as-needed basis.

“It’s never easy to let go employees, particularly those who have been with the Company for many years and who have made contributions to the Company. Though difficult, the changes we announce today are the right moves for the Company’s stockholders and provide the best opportunity to find the right strategic partner or partners,” stated Jack Lief, Chair of the ADVENTRX Board of Directors. “Mark’s willingness to join the Company as an executive and now to transition back to his prior Board role has been tremendously valuable, both to the Board and to management, and we thank him for his dedication to ADVENTRX,” added Mr. Lief.

“At this time, when conserving cash is vital, I believe I can best help the Company achieve its goals by transitioning back to my prior role as a Board member,” stated Mark Bagnall. “I plan to stay involved with the Company and will remain engaged in the Company’s on-going strategic partnering discussions.”

Strategic Opportunities
ADVENTRX is seeking partners for one or both of its two late-stage oncology programs, both of which are novel reformulations of currently approved products and are designed to improve the safety profiles of the approved products without affecting efficacy. ANX-514 (docetaxel emulsion for injection) is a reformulation of the blockbuster chemotherapeutic agent, Taxotere®. In 2007, the aggregate worldwide market for Taxotere was in excess of $3 billion. ANX-530 (vinorelbine injectable emulsion) is a reformulation of Navelbine® which, despite being a generic product for a number of years, still sells in excess of $200 million a year world-wide. Both of the Company’s product candidates have the potential to be on the market in 2010.

About ANX-530 (vinorelbine emulsion)
ANX-530 is a novel emulsion formulation of the chemotherapy drug vinorelbine. ANX-530 emulsifies vinorelbine into a homogeneous suspension of nanoparticles that is designed to protect the venous endothelium during administration into a peripheral vein. Navelbine®, a branded formulation of vinorelbine, is approved in the U.S. to treat advanced non-small cell lung cancer as a single agent or in combination with cisplatin, and approved in the European Union to treat non-small cell lung cancer and advanced or metastatic breast cancer.

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.
