Apricus Biosciences Sells Bio-Quant CRO Subsidiary to BioTox Sciences

Company to Focus on Generation of Revenues From Commercialization of Drug Pipeline Based on NexACT(R) Delivery Technology

SAN DIEGO, July 6, 2011 (GLOBE NEWSWIRE) — Apricus Biosciences, Inc. (“Apricus Bio”) (Nasdaq:APRI) announced today that it has sold its wholly-owned subsidiary, Bio-Quant, Inc. (“Bio-Quant”), a specialty biotechnology Contract Research Organization (“CRO”), to BioTox Sciences (“BioTox”), a San Diego-based CRO. Under terms of the agreement, Apricus Bio will receive a minimum of $5 million in up-front and future earn-out payments, with the potential for as much as $20 million over the next ten years, based on BioTox’s currently projected revenues. Additionally, Apricus Bio has retained all NexMed-related research conducted by Bio-Quant as well as the profitable Bio-Quant diagnostic kit business.

“While our Bio-Quant subsidiary has been driving revenues over the past year, this divesture represents a key strategic decision for Apricus Bio, as licensing revenues from Vitaros® have increased during the first half of 2011, and are currently projected to constitute the majority of our revenue stream for the remainder of 2011,” stated Dr. Bassam Damaj, Chairman, President and Chief Executive Officer of the Company. “The sale enables us to focus our efforts where we believe we will generate the greatest return on investment — speeding our specialty biopharmaceutical drugs to market. While Bio-Quant has been instrumental in advancing the uses of our NexACT® technology and preclinical pipeline, we have now entered the commercialization stage with our first product and intend to focus our efforts on the generation of revenues from our drug pipeline,” continued Dr. Damaj.

Apricus Bio’s top priority is to commercialize Vitaros®, for the treatment of erectile dysfunction. Vitaros® was approved for marketing and sales in Canada in 2010, and the Company recently filed for approval in Europe. Management is in advanced partnering negotiations for Vitaros® in Canada and/or Europe and expects to announce a partnership in the second half of 2011. In addition, Apricus Bio is focused on developing and commercializing the other 12 products and product candidates in its pipeline, including Femprox®, MycoVa™ and PrevOnco™.

Bio-Quant, founded in 2001, is one of San Diego’s most experienced CROs for non-GLP (good laboratory practices) contract drug discovery and pre-clinical development services, specializing in oncology, inflammation, immunology and metabolic diseases. Bio-Quant has clients world-wide. Revenues are generated from pre-clinical contract services and housing services.

During 2010, the Bio-Quant CRO business helped advance Apricus Bio’s proprietary NexACT® technology and increase its product and product candidate portfolio from four products to 13. With the divestiture of Bio-Quant, Apricus Bio has decided to outsource its primary preclinical CRO work for its NexMed subsidiary and narrow its focus on commercializing its late stage products — Vitaros® for erectile dysfunction, Femprox® for female sexual arousal disorder, MycoVa™ for nail fungus, PrevOnco™ for liver cancer and RayVa™ for Reynaud’s Syndrome — in addition to continuing to develop the eight other, earlier stage product candidates in its pipeline.

BioTox is a San Diego CRO founded in 2007 that focuses primarily on GLP studies and has been interested in expanding its operations in San Diego on the non-GLP side.

“We look forward to seeing BioTox achieve even greater success, which will result in greater earn-out payments for Apricus Bio,” said Dr. Damaj.

“We were actively looking for opportunities to expand our footprint in the Discovery CRO area and add more In-Vitro and In-Vivo disease models to increase the range of services we currently offer to our clients,” stated BioTox’s President, Sami Abunadi, in a company statement. “Bio-Quant offers a long and successful history in non-GLP preclinical research in areas such as oncology, inflammation, immunology, metabolic diseases and high throughput screening capabilities. We believe that this transaction will not only be revenue and earnings enhancing and highly valuable to our shareholders, but will also provide both a superior and quicker entry point than the other build or buy options we considered,” said Mr. Abunadi.

In addition to adding key services and becoming a major participant in Southern California, BioTox can now scale its operation and reach to become a true national and global presence. BioTox intends to build on its present IND and NDA enabling In-Vivo GLP toxicology offerings, and as such, expects to be able to offer both Bio-Quant’s and BioTox’s clients a more attractive strategic outsourcing alliance with proven economic and scientific depth.

“We can now take our clients’ compounds through the preclinical drug development process and utilize state-of-the-art capabilities by integrating Bio-Quant’s study execution software platform Intranet with BioTox’s Sponsor friendly and GLP compliant study Data Acquisition Software, called iAdavantage, and thus accelerate the development process economically and effectively” Mr. Abunadi added.
