Study Endpoints

Primary Endpoints

Duration of Severe Oral Mucositis (SOM)
approx. 13 weeks

To assess the efficacy of SGX942 compared to placebo in decreasing the duration of severe oral mucositis (SOM; defined as World Health Organization \[WHO\] Grade ≥3). Duration of SOM is defined as the number of days from the onset of SOM until resolution of SOM. OM is evaluated using the published WHO OM grading scale that uses a scale of 0 to 4, with SOM defined as a score ≥3.

Number of Oral Ulcers
4 weeks

The number of oral ulcers were counted at baseline and each visit during the treatment period.

Number of Genital Ulcers
4 weeks

The number of genital ulcers will be counted at baseline and each visit during the treatment period.

Secondary Endpoints

Change in Pain of Oral Ulcers From Baseline to End of Treatment
4 weeks
Change in Pain of Genital Ulcers From Baseline to End of Treatment
4 weeks
Residual Severe Oral Mucositis (SOM)
4 weeks after end of therapy
