Replicated Studies Open New Product Opportunities in the Rheumatoid Arthritis Market

LOS ANGELES, CA -- (MARKET WIRE) -- July 28, 2006 -- Molecular Pharmacology (USA) Limited (OTCBB: MLPH) announced today that independent, replicated and multi-centered in-vitro studies had shown that the company's anti-cytokine drug, MPL-104, potently inhibits the secretion of TNF-alpha in inflammatory conditions. The secretion of the cytokine TNF-alpha underlies a range of debilitating inflammatory diseases such as rheumatoid arthritis, lupus, Crohn's disease, psoriasis, and ankylosing spondylitis, and is considered to be the main factor in driving inflammation.

TNF-alpha inhibitors for the treatment of Rheumatoid Arthritis (RA) are not new, as oral products such as Enbrel, Centocor/Schering-Plough/Tanabe's Remicade (infliximab), and Humira already exist in the market place. According to Decision Resources, Inc. (, the existing products had combined sales of $4.6 billion in 2005, and they project this market segment will undergo robust growth in the United States, United Kingdom, France, Germany, Italy, Spain, and Japan reaching more than $10 billion by 2015.

"What makes MPL-104 such an exciting project is that it is directed at producing products that do not directly compete with the current market leaders, and complement their functionality," said MPL President and Chief Executive Officer Jeffrey Edwards. "Irrespective of how well medicated RA sufferers are, it is very common for them to have one or more unresponsive joints. Elevating systemic medication levels to accommodate these is not a clinical option, because of the potential of adverse side effects. This is the therapeutic area where we believe MPL-104 will provide real benefits."

MPL-104 appears to be one of the very rare TNF-alpha inhibitory drugs that is small enough to be administered topically. This allows it to be formulated as a cream or serum and applied directly to the effected area or joint, without altering systemic levels by any significant amount. We believe this will allow MPL-104 to be used to support and augment the total clinical efficacy of existing market leading drugs rather than be competitive to them.

In addition to the RA market opportunity, we expect the benefit of isolated application and local action has the potential to deliver similar benefits in the treatment of other inflammatory conditions, a market projected to increase to $47.8 billion by 2010. (BCC Research --

MPL-104 emerged following an extensive research and isolation program designed to reveal the biological mechanism behind an analgesic and anti-inflammatory product that had been approved and marketed successfully in Australia for almost 18 years with an unblemished safety and efficacy record in humans.

"We believe this provides MPL with a very early path to market, and a stepping-stone platform into the European, Asian and ultimately the US markets for a range of disease specific products that utilise the Company's broadening biological mediator platform."
