AN2728

AN-2728, being developed by Anacor Pharmaceuticals Inc, is a topically administered, boron-containing, anti-inflammatory compound that inhibits PDE4 activity and thereby suppresses the release of TNFalpha, IL-12, IL-23 and other cytokines. At the time of publication, three phase Ib clinical trials, a IIa trial and a IIb trial of AN-2728 in patients with psoriasis had been completed; the compound was also undergoing phase II development for atopic dermatitis, but no data were available for this indication. AN-2728 was reported to be well tolerated and to demonstrate significant effects on markers of efficacy, with results that were comparable to positive controls. AN-2728 appears to have good therapeutic potential, although further and larger trials are required to assess the long-term safety and characterize the broad utility of this drug.
