Brief Summary:
The purpose of this study is to determine if RRx-001, which is added on to the cisplatin and radiation treatment, reduces the incidence of severe oral mucositis in patients with head and neck cancers. All patients in this study will receive 7 weeks of standard of care radiation therapy given with the chemotherapy agent, cisplatin. Patients will receive RRx-001 or placebo before start of standard of care treatment.

Condition or disease Intervention/treatment Phase
Oral Mucositis Drug: RRx-001 Radiation: Intensity Modulated Radiation Therapy (IMRT) Drug: Cisplatin for injection 100 mg/m2 Phase 2

Detailed Description:
The standard treatment for head and neck cancer currently includes a chemotherapy drug called cisplatin that is given by intravenous (IV) infusion and radiation, which is delivered from a machine that precisely targets the tumor. One common and unfortunate side effect of treatment with cisplatin and radiation is oral mucositis, which refers to irritation of the lining of the mouth. Oral mucositis is a serious problem 1) because the open mouth sores from oral mucositis may lead to severe pain, nutritional problems and dehydration from an inability to eat and drink, an increased risk of infection from bacteria and fungus and delay or discontinuation of treatment and 2) because there is only one approved therapy to treat or prevent it.

Primary Outcome Measures :
  1. Incidence of Severe Oral Mucositis (SOM) through Intensity-modulated radiation therapy (IMRT) [ Time Frame: Estimated up to 18 Months ]
    The incidence of SOM defined as the proportion of patients with any WHO Grade >= 3 (severe to life threatening) oral mucositis during the observation period from the start of CRT through IMRT


Secondary Outcome Measures :
  1. Duration of Severe Oral Mucositis (SOM) through Intensity-modulated radiation therapy (IMRT) [ Time Frame: Estimated up to 18 Months ]
    Duration of SOM (through the last day of radiation therapy, DoSOM). Its principal analysis employs the probability of being in response (PBIR), an intuitive concept based on the realization that the duration of response which is quantified as the area under the curve delimited by the duration of exposure (x axis) and the response probability (y axis).

  2. Duration of Severe Oral Mucositis (SOM) through 60 Gy [ Time Frame: Estimated up to 18 Months ]
    Duration of SOM (through 60 Gy, DoSOM) is compared between RRx-001 arms and Placebo using a two-sided log-rank test.

  3. Time to onset of Sever Oral Mucositis (ttSOM) [ Time Frame: Estimated up to 18 Months ]
    Time onset to SOM (ttSOM) is defined as the time interval measured from the start of the observation period to the first time SOM is observed.

  4. Incidence and severity of dysphagia [ Time Frame: Estimated up to 18 Months ]
    Incidence and severity of dysphagia will be analyzed similarly to the primary efficacy endpoint.

  5. Cumulative radiation dose to onset of SOM [ Time Frame: Estimated up to 18 Months ]
    Cumulative radiation dose to onset of SOM is compared between RRx-001 arms and placebo

  6. Incidence of grade 4 oral mucositis [ Time Frame: Estimated up to 18 Months ]
    Incidence of grade 4 oral mucositis through 60 Gy

  7. Narcotic use through resolution of SOM [ Time Frame: Estimated up to 18 Months ]
    Narcotic use through resolution of SOM will be analyzed similarly to the cumulative radiation dose

  8. Incidence of Severe Oral Mucositis through 60 Gy of the Radiation Treatment Plan [ Time Frame: Estimated up to 18 Months ]
    incidence of SOM defined as the proportion of patients with any WHO Grade >= 3 (severe to life threatening) oral mucositis during the observation period from the start of CRT through 60 Gy
