Sydney, Australia | August 28, 2008 | Biotechnology company Arana Therapeutics Limited (ASX: AAH) today announced that it has completed recruitment in its Phase II dose-ranging psoriasis study for its anti-inflammatory drug ART621. Completion of recruitment means that formal results of the study should be available in early 2009.

* Patient recruitment in psoriasis trial for Arana’s inflammatory drug ART621 completed; results expected in Q1 2009
* IND to be submitted in Q4 2008
* Rheumatoid arthritis trial planned to commence by end Q4 2008

Arana also confirmed that it is planning to submit an Investigational New Drug (IND) application for ART621 in the rheumatoid arthritis indication in the fourth quarter of 2008.

Commenting on these developments, CEO John Chiplin said: "We are pleased with the clinical progress of ART621 and are excited to be finalising the IND documentation, the submission of which is a crucial milestone towards the commercialisation of ART621."

“Subject to feedback from the FDA (U.S. Food and Drug Administration), we look forward to the commencement of our rheumatoid arthritis program by the end of this year which we have been carefully planning for some time now.” Dr Chiplin said.

ART621 is an “anti-TNF” – a class of drugs used for the treatment of inflammatory diseases such as rheumatoid arthritis, psoriasis and Crohn’s disease. ART621 works by blocking the action of TNF (tumour necrosis factor) a protein which is involved in the generation of inflammation.

“We are targeting two of the key anti-TNF markets – rheumatoid arthritis and psoriasis. If successful in trials, the unique nature of our product should enable us to gain a valuable share of the large and growing anti-TNF market” Dr Chiplin said.

The total market for existing anti-TNF’s, Remicade®, Humira® and Enbrel®, was US$12.8 billion in 2007. This market is expected to exceed US$20 billion by 2012.
