I had seen their PR a few weeks back. Although they had written in the PR (which I believe they accidentally wrote incorrectly) "in the overall incidence of SOM through 60 Gy of radiation", it is different than what is stated on clinicaltrials.gov which states:
Primary Outcome Measures : Duration of Radiation Induced Severe Oral Mucositis per WHO Criteria, Through a Minimum of 60 Gy IMRT Delivered to the Tumor [ Time Frame: Minimum of 60 Gy administered to tumor, approximately 30 IMRT fractions, which is estimated to be 6-7 weeks. ] Evaluate and compare the duration of severe OM, as assessed from the first determination of ≥ Grade 3 OM to the first instance of non-severe OM (≤ Grade 2), without a subsequent instance of ≥ Grade 3.
