About
This phase II trial compares the effectiveness of adding BMX-001 to usual symptom management versus usual symptom management alone for reducing oral mucositis in patients who are receiving chemoradiation for head and neck cancer. Oral mucositis (inflammation and mouth sores) is a common side effect of chemoradiation that can cause pain and difficulty swallowing. Usual management of these side effects typically consists of using mouth rinses and pain medications during treatment and for several weeks after completion of treatment. BMX-001 neutralizes harmful substances in the body, preventing damage to macromolecules such as DNA and minimizes free radical-related toxicity in normal tissues. Adding BMX-001 to usual symptom management may be more effective than usual symptom management alone at reducing oral mucositis in patients receiving chemoradiation for head and neck cancer.
Full description
PRIMARY OBJECTIVE:
I. To compare the incidence of severe oral mucositis (SOM) between manganese superoxide dismutase (MnSOD) mimetic BMX-001 (BMX-001) and placebo, defined as >= grade 3 per World Health Organization (WHO) criteria from the start of radiation through 4 weeks after completion of study treatment, with additional assessments at 6, 8 and 12 weeks after completion of study treatment.
SECONDARY OBJECTIVES:
I. To compare the duration of SOM in the BMX-001 arm versus (vs.) placebo arm. II. To assess the difference between arms in the Oral Mucositis Weekly Questionnaire-Head and Neck (OMWQ-HN) change score from baseline to 4 weeks after the end of chemoradiation.
III. To describe the incidence and severity of xerostomia and radiation dermatitis, as measured by Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0, in both arms.
IV. To compare the duration of radiation dermatitis in the BMX-001 arm vs. placebo arm.
V. To describe toxicity, as measured by CTCAE v5.0 and Patient Reported Outcome (PRO)-CTCAE, in both arms.
EXPLORATORY OBJECTIVES:
I. To assess the between arm difference in progression-free survival (PFS). II. To assess the between arm difference in overall survival (OS). III. Data demonstrating improvement in pain, as measured by reduction in narcotic use between BMX-001 versus usual care.
IV. Collect serum and plasma for future translational research analyses.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM 1: Patients receive cisplatin once weekly (QW) or once every 3 weeks (Q3W) and undergo image-guided intensity-modulated radiation therapy once daily (QD) 5 days per week for 7 weeks per standard of care (SOC). In addition to usual symptom management, patients receive placebo subcutaneously (SC) as early as 96 hours and no later than one hour prior to their first dose of radiation therapy, and as early as 96 hours and no later than 48 hours prior to first dose of cisplatin. Patients then receive placebo SC twice a week (BIW) for 8 weeks (16 doses). Patients also undergo computed tomography (CT) and/or magnetic resonance imaging (MRI) on study and may optionally undergo collection of blood, serum, and/or plasma throughout the study.
ARM 2: Patients receive cisplatin QW or Q3W and undergo image-guided intensity-modulated radiation therapy QD 5 days per week for 7 weeks per SOC. In addition to usual symptom management, patients receive BMX-001 SC as early as 96 hours and no later than one hour prior to their first dose of radiation therapy, and as early as 96 hours and no later than 48 hours prior to first dose of cisplatin. Patients then receive BMX-001 SC BIW for 8 weeks (16 doses). Patients also undergo CT and/or MRI on study and may optionally undergo collection of blood, serum, and/or plasma throughout the study.
After completion of study treatment, patients are followed up at 1, 2, 3, 6, 12, and 24 months.

Inclusion and exclusion criteria
Inclusion Criteria:
-
Patients must be planned to receive radiation and concurrent cisplatin chemotherapy as definitive therapy. Patients planned to receive concurrent cisplatin and radiation therapy in the adjuvant setting are not eligible.
-
At least two subsites (buccal mucosa, lips, retromolar trigone, floor of mouth, oral tongue, tonsil, soft palate, or hard palate) must have at least 1cc or 1% of the subsite volume receiving >= 50 Gy. In cases of uncertainty, the enrolling clinician can ensure coverage by inspecting the 50 Gy isodose line and using the table describing the anatomic boundaries of the individual subsites contained within the extended cavity contour. The two or more subsites receiving >= 50 Gy must be documented by the enrolling physician and will be reviewed centrally to confirm eligibility.
-
Pathologically confirmed (histologically or cytologically) squamous cell carcinoma of the oropharynx, larynx, hypopharynx, nasopharynx, or oral cavity.
-
P16 and/or human papillomavirus (HPV) status (via polymerase chain reaction [PCR] or in situ hybridization [ISH]) must be documented for patients with oropharynx cancer.
-
No definitive clinical or radiologic evidence of metastatic (M1) disease related to current diagnosis.
-
Able to receive intensity-modulated radiation therapy (IMRT) delivered as daily fractions of 2.0 Gy once per weekday with a cumulative radiation dose of 70 Gy.
-
Age >= 18.
-
Zubrod performance status of 0-2.
-
Potassium ≥ institutional lower limit of normal (LLN) and magnesium ≥ institutional LLN. Oral or intravenous (IV) replacement therapy of potassium or magnesium is permitted if parameters can be met after repletion.
-
Absolute neutrophil count (ANC) >= 1,500 cells/mm^3.
-
Platelets >= 100,000 cells/mm^3.
-
Hemoglobin >= 9.0 g/dl (Note: The use of transfusion or other intervention to achieve hemoglobin [Hgb] >= 10.0 g/dl is acceptable).
-
Adequate renal function defined as creatinine clearance (CrCL) > 50 mL/min by the Cockcroft-Gault formula.
-

- For standard management of oral mucositis, clinicians may consult the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) Clinical Practice Guidelines for the Management of Mucositis Secondary to Cancer Therapy https://acsjournals.onlinelibrary.wiley.com/doi/epdf/10.1002/cncr.33100. The only intervention against mucositis that is supported by level I evidence is low-level laser therapy (LLLT). Honey is rated at level II and benzydamine, which isn't available in the United States (US), is rated at level III. There are no other positively rated interventions.
- LLLT is prohibited in this study as its availability remains limited, it is not Food and Drug Administration (FDA) approved in the US, and it is considered investigational in many circumstances requiring enrollment in a dedicated protocol who requirements could conflict with this one. Therefore, institutions that use LLLT should only enroll patients who would not be eligible for (or do not want) that intervention. Honey is not on the list of prohibited medications for this study. Given the MASCC recommendation, benzydamine is allowed, although there is lack of availability in the United States of America (USA). The other listed prohibited medications are not recommended by MASCC and some are potentially harmful, such as glutamine, which is associated with mortality in patients receiving stem cell transplant.
-
No history of allergic reaction to the study agent(s), compounds of similar chemical or biologic composition to the study agent (s) (or any of its excipients).
-
Childbearing potential is defined as any person who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal.
