When the sample size is small, the placebo rate can change quickly simply by chance. As Cox pointed out, 60% was a fluke. Soligenix had 74% which was more typical.
If those five patients didn’t drop out due to severe OM, the incidence rate would be 17 of 25 patients, or 68% placebo rate. Phase 3 will contain a larger sample size so the placebo rate should be closer to the 70-75% range.
