Current Primary Outcome Measures (submitted: August 3, 2022)

Duration of Severe Oral Mucositis (SOM) [ Time Frame: 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.

Original Secondary Outcome Measures (submitted: July 28, 2017)

• Severity-weighted duration of SOM by Area-Under-the-Curve (AUC) for the WHO Grade ≥3 by time plot [ Time Frame: approx. 13 weeks ]
  To assess the impact of SGX942 on the severity-weighted duration of SOM
• Duration of SOM [ Time Frame: approx. 13 weeks ]
  To assess the impact of SGX942 compared to placebo on duration of SOM; in all randomized patients
• Duration of ulcerative OM [ Time Frame: approx. 13 weeks ]
  To assess the impact of SGX942 compared to placebo on the duration of ulcerative OM (UOM; defined as WHO Grade ≥2)
• Incidence of SOM [ Time Frame: approx. 13 weeks ]
  To assess the impact of SGX942 compared to placebo on the incidence of SOM
• Number of radiation treatment (RT) breaks [ Time Frame: approx. 9 weeks ]
  To assess the impact of SGX942 compared to placebo on the number RT breaks
• RECIST categorization of the primary tumor [ Time Frame: approx. 11 weeks ]
  To assess the impact of SGX942 compared to placebo on RECIST (Response Evaluation Criteria In Solid Tumors) categorization of the primary tumor at 4 weeks after completion of RT
• Incidence of reported presumed bacterial infections [ Time Frame: approx. 13 weeks ]
  To assess the impact of SGX942 compared to placebo on incidence of reported presumed bacterial infections between Baseline and 6 weeks after completion of RT by total number and by severity of infection, graded using the National Cancer Institute's (NCI's) Common Terminology Criteria for Adverse Events (CTCAE)
