Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 266 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Pivotal, Double-Blind, Randomized, Placebo-Controlled, Multinational Study of SGX942 (Dusquetide) for the Treatment of Oral Mucositis in Patients Being Treated With Concomitant Chemoradiation for the Treatment of Squamous Cell Carcinoma of the Head and Neck
Actual Study Start Date : December 4, 2017
Actual Primary Completion Date : June 24, 2020
Actual Study Completion Date : June 24, 2021

Arm Intervention/treatment
Experimental: SGX942
Patients are randomized 1:1 active/placebo.
Drug: SGX942
1.5 mg/mL SGX942 administered as a 4 minute IV infusion, twice per week starting within 3 days after initiating radiation therapy and continuing through 2 weeks after radiation therapy ends.
Other Name: Dusquetide

Placebo Comparator: Placebo
Patients are randomized 1:1 active/placebo.
Drug: Placebo
Placebo is 0.9% sodium chloride (normal saline). The treatment preparation, frequency and duration of therapy are identical to that of the active drug.

Primary Outcome Measures :
  1. 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.

  • Evidence of significant renal, hepatic, hematologic, or immunologic disease determined by any one of the following: Estimated creatinine clearance <30 mL/min; ALT or AST level greater than 10-fold the upper limit of normal or total bilirubin greater than 3-fold the upper limit of normal; Manifestations of end-stage liver disease, such as ascites or hepatic encephalopathy; Thrombocytopenia; or CD4+ T cell count below 200 cells per μL
  • Evidence of immediate life-threatening disease or a life expectancy of less than 3 months
  • Women who are pregnant or breast-feeding
