Byetta will probably be a bigger money maker for Amylin since there is potential more patients for Byetta than Symlin (Symlin is for insuiln users, Byetta is being tested with oral medications).
BYETTA Shown to Reduce Blood Sugar Levels When Added to Patients Treated With TZDs
A1C, a measure of glucose control over the previous three months, improved by approximately 0.9 percentage points at the end of the 16-week study for subjects receiving twice daily 10 microgram subcutaneous injections of BYETTA in addition to their usual TZD or TZD plus metformin regimen, compared to those on their prior oral medications receiving placebo. At the beginning of the study, the average A1C of study participants was approximately 7.9 percent. Sixty-two percent of subjects receiving BYETTA who entered the study with an A1C greater than 7 percent achieved an A1C of 7 percent or less compared to sixteen percent of similar subjects on placebo. The American Diabetes Association recommends a target A1C of less than 7 percent.
