All 13 patients in the twice-weekly arm had a reduction in serum IGF-1 levels from baseline to week 14. Antisense said the 200 mg ATL1103 given 3 times in week 1 followed by once-weekly 200 mg ATL1103 regimen missed the endpoint. In the once-weekly arm, 4 of 13 patients had a >20% reduction in serum IGF-1 levels. In January, the company reported interim data from the first 8 patients in the trial showing that ATL1103 was well tolerated (see BioCentury, Jan. 27). ...
