RK-0202 in Preventing Oral Mucositis in Patients Who are Undergoing Radiation Therapy for Cancer of the Mouth, Throat, or Salivary Glands

Basic Trial Information

Objectives

1. Compare the efficacy of 2 different doses of RK-0202 rinse on incidence, severity, and time to onset of oral mucositis in patients with tumors of the oral cavity, oropharynx, nasopharynx, salivary glands, or supraglottic region who are undergoing radiotherapy.
2. Determine the safety and tolerability of this drug in these patients.
3. Compare the effect of placebo mouthwash vs standard care in these patients.

Entry Criteria

Disease Characteristics:

• Histologically confirmed tumors of the oral cavity, oropharynx, nasopharynx, salivary glands, or supraglottic region
• Planned radiotherapy that would deliver a minimum of 60 Gy over 5-8 weeks to at least 2 cm² of 3 or more of the following oral cavity anatomical sites:
  • Upper or lower lip
  • Right or left buccal
  • Right or left lateral/ventral tongue
  • Right or left dorsal tongue
  • Right or left floor of mouth
  • Right or left soft palate
  • Right or left tonsil region
  • Right or left hard palate
  • Nasopharynx
• Radiotherapy must begin within 9 weeks after prior surgery and regimens may comprise the following:
  • Single-dose daily fractionated regimen (daily maximum of 2.2 Gy)
  • Hyperfractionated regimen (daily maximum of 2.4 Gy)
  • Concurrent boost (daily maximum of 3.3 Gy during boost)
• No oral mucositis present
• No T1 or T2 glottic tumors

Expected Enrollment

A total of 105 patients (30 in each active drug arm, 30 in the placebo arm, and 15 in the standard care arm) will be accrued for this study within 1 year.

Outcomes

Area under the curve (AUC) for the mean Oral Mucositis Assessment Scale (OMAS) scores over cumulative radiotherapy (RT) dose

AUC for the mean OMAS anatomic sites over cumulative RT dose
Distribution of mean mucositis scores over equal sequential intervals of radiation
Time to onset of mucositis by OMAS, WHO, and NCI
Mean and peak scores and extent of ulceration-number of anatomic sites at each evaluation with an OMAS ulceration score of 3
Proportion of patients with none-to-mild or moderate-to-severe mucositis at each specified interval of RT
Oral symptomatic assessment
Analgesic use
Intent to treat analyses of efficacy and safety data
Safety and tolerability

Outline

This is a randomized, placebo-controlled, double-blind, parallel-group, multicenter study. Patients are randomized to 1 of 4 arms.

• Arm I: Patients receive oral RK-0202 mouthwash for 1 minute (gargle for 5 seconds) and then expectorate. RK-0202 is administered 6 times daily, with at least 1 dose administered 30 minutes before each radiotherapy treatment.
• Arm II: Patients receive a different dose of RK-0202 administered as in arm I.
• Arm III: Patients receive placebo mouthwash, which is administered on the same schedule as in arm I.
• Arm IV: Patients receive standard care.

Treatment in all arms begins on the first day of radiotherapy and continues until radiotherapy is completed.

Patients are followed at 30 days and then at 3 and 12 months.
