Brief Summary

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 swallow...

• Sex: All
• Target Recruitment: 98

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.

• Total bilirubin =< 2 x institutional upper limit of normal (ULN) (not applicable to patients with known Gilbert's syndrome).

• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional ULN.

• No prior radiotherapy that would result in overlap of radiation treatment fields with planned treatment for study cancer, e.g., breast cancer with irradiation of the supraclavicular fossa/level 4 neck.

• No concurrent treatment with nitrates or other drugs that may, in the judgment of the treating investigator, create a risk for a precipitous decrease in blood pressure.

• No prior history of gross total excision of both primary and nodal disease; this includes tonsillectomy, local excision of primary site, and nodal excision that removes all clinically and radiographically evident disease. In other words, to participate in this protocol, the patient must have clinically or radiographically evident gross disease for which disease response can be assessed.

• No current treatment of adjuvant post-operative (op) chemoradiation.

• No systemic treatment with inducers or strong inhibitors of cytochrome P450 =< 4 days before registration. Note: Patients undergoing steroid treatment as a component of the anti-emetic regimen for cisplatin are eligible for the study.

• No prior unrelated malignancy requiring current active treatment with the exception of cervical carcinoma in situ, basal cell skin carcinoma, resected T1-2N0M0 differentiated thyroid cancers, Ta bladder cancers, or low risk prostate cancer.

• No clinically significant hearing impairment that precludes cisplatin, as per physician assessment.

• No serious cardiovascular disease or cerebrovascular disease in the last 6 months prior to study enrollment; defined as a cerebrovascular accident, myocardial infarction, unstable angina, serious cardiac arrhythmia uncontrolled by medication or with the potential to interfere with protocol treatment, or current New York Heart Association (NYHA) grade II or greater congestive heart failure (CHF), or admission within last 6 months for CHF exacerbation; (Note: Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification).

• No significant vascular disease (e.g., aortic aneurysm requiring surgical repair or recent arterial thrombosis) within 6 months prior to enrollment.

• No history or evidence upon physical/neurological examination of central nervous system disease (e.g., seizures) unrelated to cancer unless adequately controlled by medication.

• Acute bacterial, viral, or fungal infection requiring intravenous antimicrobials within 7 days of enrollment.

• No history of chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy within 30 days of registration.

• No known personal or family history of long QT Syndrome; no marked baseline prolongation of QT/corrected QT (QTc) interval (i.e., ≥ 2 electrocardiograms [EKGs] in prior 3 months of a QTc interval > 450 milliseconds (ms) for males and > 470 ms for females using the specific/usual choice by clinical center for correction factor.

• Persistent grade 3-4 (CTCAE version 5.0) electrolyte abnormalities must be reversible to ≤ grade 1 with supplementation.

• Poorly controlled hypertension (systolic blood pressure [SBP] > 160 and/or diastolic blood pressure [DBP] > 95) over 2 repeated measures within 30 days prior to registration.

• No grade >= 2 oral mucositis per CTCAE version 5.0.

• No grade >= 2 hypotension per CTCAE v. 5.0.

• No medical necessity for medications listed as prohibited.

  • 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.

Primary Outcome Measures

Name	Time	Method
Incidence of severe oral mucositis (SOM)	From start of radiation through 4 weeks after completion of study treatment	Will be defined as \>= grade 3 per World Health Organization criteria. The difference in proportions between the two treatment arms would be tested using a test of proportions z-test with a one-sided significance level of 5%.

Secondary Outcome Measures

Name	Time	Method
Duration of SOM	From first determination of >= grade 3 oral mucositis (OM) to the first instance of non-SOM (=< grade 2), without subsequent instance of >= grade 3 within the following 4 weeks	The mean duration will be compared between arms using a t-test.
Time to SOM	From date of randomization to date of first determination of >= grade 3 OM, assessed through 12 weeks after completion of chemoradiation	Gray's test will be used to assess between treatment arm comparisons. Cause-specific Cox proportional hazards models will be used to evaluate the effect of stratification factors and other relevant covariates.
Incidence and duration of xerostomia and radiation dermatitis	Up to 24 months after completion of chemoradiation	The rate of any grade and grade ≥ 3 xerostomia and radiation dermatitis, separately, will be compared between arms using a chi-square test. The mean duration will be compared between arms using a t-test.
Incidence of toxicity	Up to 24 months after completion of chemoradiation	Adverse events (AEs) will be graded by the physician-reported Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 and also measured using the Patient Reported Outcome-CTCAE. Counts of all AEs by grade will be provided by treatment arm.
Patient reported oral mucositis	Up to 24 months after completion of chemoradiation	Will be measured by the Oral Mucositis Weekly Questionnaire (OMWQ). Decline within patients using a minimally important difference of 7 will be compared between arms at each timepoint using a chi-square test, or Fisher's exact test in the case of small cell counts.
