• Example 1 Patient group and clinical study
• Radiation fields to include at least two mucositis sites at risk (buccal mucosa, floor of mouth, ventral and lateral tongue, soft palate) in which both sites receive a miniminn cumulative dose of 55 Gy
• EC- 18 was administered in varying patients of the treatment group up to 2000 mg/day.
• Recommended therapy was 500 mg EC-18 capsule administered 4 times throughout the day (e.g., 2 capsules of 500mg EC-18 administered within 30 mins after taking breakfest and dinner) for a total daily dosage of 2000 mg EC-18 per day.
• Treatment protocol lasted 7 weeks while radiation therapy and cisplatin therapy continued during the same time.
• the EC-18 treatment group demonstrated clear therapeutics benefit overthe control group, including reduction of mucositis symptoms.
• Stage 1 To Evaluate safety and MTD that can be used for Stage 2 iDSMB: Data and Safety Monitoring Board reviewed safety data every 2 weeks and approved for Stage 2 using MTD 2000mg

• FIGS. 2A-2B summarize efficacy results. When measured Median of Duration and Incidence of SOM from the time when SOM develops to w-hen SOM has been resolved; we see very strong efficacy- results. With placebo group, we calculated median Duration of SOM almost 14 days compared to EC- 18 group which never developed SOM
• FIGS. 3A-3B graph shows percentage of SOM incidence at each week interval. SOM does not begin until week 3 and peaks at w-eek 7 (by- then, cumulative radiation dose is 70Gy) and even at week 8 which is 1 week after the last radiation treatment. As can be seen in FIGS.
• SOM incidence for EC-18 group is less than placebo group (PP Population or PP).

• the median value of 11.5 days was delayed in EC-18 2,000 mg group compared with the placebo group (37 days in EC-18 groups vs. 25.5 days in placebo).
• FIG. 7 shows covariate analysis based on Cisplatin regimen and HPV status.
• the observed results for incidence of SOM in subjects were less in the EC-18 2000 mg group as compared to the Placebo group with weekly cisplatin (37.5% vs. 70.0%), and with tri-weekly cisplatin (66.7% and 70.0%), respectively.
• the observed results for incidence of SOM in subjects with HPV+ were less in the EC-18 2000 mg group as compared to the Placebo group (35.3% vs. 66.7%). Whereas, there was no difference observed in the subjects with HPV- in the EC-18 2000 mg group as compared to the Placebo group (75% vs. 71.4%).
• the plasma sample collected from the blood of patients listed in (Table 1 below) was thawed and centrifuged at 10,000 rpm at 4°C for 2 minutes, and the supernatant was used for analysis. The supernatant was serially diluted, and 50ul of the samples were dispensed to each well in a 96-well plate. 50ul of diluted Microparticle Cocktail (R&D systems) shown in Table 2 was added to each well containing samples and incubated for 2 hours at room temperature on a shaker at 800 rpm. The sample mixture was removed and washed with 100 ul of washing buffer three times.
