Antisense management will be available for meetings in New York on November 7-9.

The Company's current Phase IIa trial is a study in 80 patients to assess the safety and efficacy of ATL1102 as a treatment for relapsing remitting MS.

ATL1102 is a second-generation antisense inhibitor of CD49d, a subunit of VLA-4 (Very Late Antigen-4). It is believed that the inhibition of VLA-4 prevents white blood cells from entering sites of inflammation, thereby halting the progression of inflammatory diseases such as MS. VLA-4 is a clinically validated target in the treatment of MS. Antisense inhibition of VLA-4 has demonstrated positive effects in an animal model of MS and the data has been published - Myers et al., J Neuroimmunol 160, 12-24 (2005).
