Iomai Study Shows Self-Applied Travelers' Diarrhea Vaccine Patch Comparable to Clinician-Applied Vac...( GAITHERSBURG Md. Feb. 12 /- Iomai...),Health

GAITHERSBURG, Md., Feb. 12 /PRNewswire-FirstCall/ -- Iomai Corporation (Nasdaq: IOMI) today announced the interim results of a study that showed that the second dose of the two-dose regimen for its novel, patch-based travelers' diarrhea vaccine yields a robust immune response when self-applied by subjects outside of a clinical setting.

The 160-subject study, part of an extensive Phase 2 program for the vaccine, measured the immune response to the vaccine patch, which is approximately the size and shape of an adhesive bandage. Four groups were evaluated: two groups received both doses of the vaccine from a medical professional and two other groups of volunteers administered the second vaccine patch themselves. All groups had robust responses to the vaccine, and a statistical analysis of immune parameters following vaccination showed no significant differences between treatment groups at any time point.

"These results confirm our belief that the Iomai patch can be effectively used by patients without a health care provider present, removing the need for a second trip to a travel clinic," said Stanley C. Erck, Iomai's president and chief executive officer. "Our research has shown that self-application of the second dose further enhances the market potential of this product."

As with past studies of the vaccine, no serious vaccine-related adverse events were reported.

Iomai is completing its Phase 2 program and plans to conduct a Phase 3 efficacy study during summer of 2009, when the travelers' diarrhea season in Latin America is at its peak. Based on the results of the self-application study, Iomai is evaluating the feasibility of including self-administration of the second vaccine dose in that Phase 3 study. The
