Inclusion Criteria

Subjects must meet all of the following criteria:

1. Confirmed head/neck cancer scheduled to receive at least a 28-day course of radiation to the head/neck area (radiation field must include at least one mucosal site within the oral cavity space, oropharynx, hypopharynx or larynx). Subjects must be planned to receive a minimum cumulative dose of 40 Gy and maximum dose of 72 Gy of radiation. Subjects may or may not be scheduled to receive concomitant platinum-based chemotherapy administered with radiation
2. At least 18 years of age

6. Able and willing to provide informed consent

Exclusion Criteria

Subjects must not meet any of the following criteria:

1. Receiving any other pharmacological treatment within 1 week of initiation of study treatment for oral mucositis, excluding analgesics, antibiotics, antifungals, and hydration for symptom management. Subjects must also agree to not use any other mouthwash formulations to prevent or treat mucositis during the course of the study.

   1. The subject's enrolling investigator must agree to not prescribe any other mouthwash formulations to prevent or treat oral mucositis during protocol-directed treatment (Note: subjects may receive standard of care treatment if the subject develops oral mucositis and discontinues study treatment \[or may crossover to Arm A if randomized to Arm B\]).
   2. Subjects must also agree to not use any other mouthwash formulations to prevent or treat oral mucositis during protocol-defined treatment.

   i. Agents suggested to modify oral mucositis risk or course that are not allowed include sodium bicarbonate, magic mouthwash formulations, amifostine, benzydamine, cevimeline, glutamine rinse, topical GM-CSF, interleukin-11, chlorhexidine, hydrogen peroxide, diphenhydramine, palifermin, pilocarpine, steroid rinses, sucralfate, and various oral rinse medical devices
2. Untreated or unresolved oral infections, including oral candidiasis or active lesions due to oral herpes simplex virus infection that in the opinion of the investigator would compromise study outcomes.
3. Signs and symptoms of any mouth and/or throat condition or active dental disease that would impair the ability to administer the mouthwash and/or assess the development of oral mucositis, as determined by the Investigator.
4. Presence of baseline grade \> 1 oral mucositis per WHO criteria as determined by the treating investigator
5. Receiving chronic immunosuppression as determined by the Investigator
6. Known hypersensitivity to any ingredients in the mouthwash formulations that may result in anaphylaxis.
7. Use, or suspicion of use, of illicit drugs or substances (self-reported) that may, in the opinion of the Investigator, have a reasonable chance of contributing to non-compliance, opioid abuse, drug toxicity, and/or otherwise skewing the trial result
