Miravant Medical Technologies, of Santa Barbara, Calif., said further results of a comprehensive analysis of the SnET2 Phase III data are positive. Two drug doses of SnET2 (0.5mg/kg and 0.75mg/kg) were investigated for the treatment of wet age-related macular degeneration (AMD), and showed patients who enrolled in the study had a range of baseline visual acuity and were retreated only upon disease progression. As previously reported, SnET2 did not achieve the primary efficacy endpoint when all patients were included in the top-line analysis. The company now reports that certain subsets of patients demonstrated stabilized or improved visual acuity at two years. The original data were released in January. (See BioWorld Today, Jan. 15, 2002.)

The trial compares the standard regimen of Visudyne therapy to a more frequent regimen. There are now 323 patients enrolled at 31 sites in North America and Europe. Results from the study are expected to be available in the fourth quarter of 2003.
