Summary

This phase I trial investigates the side effects and best dose of peposertib when given together with radiation therapy in treating patients with head and neck cancer that has spread to other places in the body (advanced) who cannot take cisplatin. Peposertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. This trial aims to see whether adding peposertib to radiation therapy is safe and works well in treating patients with head and neck cancer.

Objectives

PRIMARY OBJECTIVE:
I. To determine the recommended phase 2 dose (RP2D) of M3814 (peposertib) when given in combination with intensity-modulated radiation therapy (IMRT).

SECONDARY OBJECTIVES:
I. To evaluate the safety and tolerability of the combination of M3814 (peposertib) with radiotherapy.
II. To estimate the rates of grade 3 or greater acute toxicities of the regimen.
III. To estimate late toxicities of the regimen.
IV. To evaluate the clinical response rate, based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, at 3 months post completion of radiotherapy.
V. To estimate 6 and 12-month progression-free survival (PFS) in the dose expansion cohort (DEC).
VI. To estimate 6 and 12-month overall survival (OS) in the DEC.

EXPLORATORY OBJECTIVE:
I. To estimate the pharmacokinetic (PK) parameter of M3814 (peposertib) using population PK approaches.

OUTLINE: This is a dose-escalation study of peposertib.

Beginning 60-90 minutes before each radiation treatment, patients receive peposertib orally (PO) once daily (QD) and undergo IMRT daily Monday-Friday for 7 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT), magnetic resonance imaging (MRI), or receive fludeoxyglucose F-18 (18F-FDG) intravenously (IV) and undergo positron emission tomography (PET)/CT during screening and follow-up.

After completion of treatment, patients are followed up every 3 months for 2 years.

Eligibility

  1. Pathologically (histologically) proven diagnosis of HNSCC of the oral cavity, oropharynx, larynx, or hypopharynx prior to registration; * Patients with oropharynx cancer need p16 determination by immunohistochemistry (where positive is defined as greater than 70% strong nuclear or nuclear and cytoplasmic staining of tumor cells), Note: Institutions must screen patients using a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory. A rigorous laboratory accreditation process similar to the United States (U.S.) CLIA certification, such as the provincial accreditation status offered by the Ontario Laboratory Accreditation (OLA) Program in Canada, the College of American Pathologists (CAP), or an equivalent accreditation in other countries, is acceptable. The p16 results must be reported on the pathology report being submitted; * Oral cavity, larynx, hypopharynx, or p16-negative oropharynx cancer must be stages T1-2N2-3 or T3N1-3 or T4N0-3 (American Joint Committee on Cancer [AJCC] version 8); * p16-positive oropharynx cancer patients, stages T4N0-3 or T1-3N2-3 (AJCC version 8); * The patient has measurable disease as defined by the presence of at least one measurable lesion per RECIST 1.1; * Please note: A histological or pathological specimen from cervical lymph nodes with well-defined primary site documented clinically or radiologically is acceptable
  2. Clinical stage noted above should be based upon following diagnostic workup: * History/physical examination within 30 days prior to registration; * Examination by radiation oncologist or medical oncologist or otolaryngology (ENT) or head & neck surgeon 30 days prior to registration, including fiber optic exam with laryngopharyngoscopy; * Diagnostic quality computed tomography (CT) or magnetic resonance imaging (MRI) of neck, with contrast, within 30 days prior to registration. Fludeoxyglucose F-18 (18F-FDG) whole body positron emission tomography (PET)-CT scan within 42 days of registration is strongly recommended but does not replace the CT or MRI study. Note: If CT component of the PET/CT is of diagnostic quality then PET/CT can be used for eligibility, however the PET/CT scan must be done within 30 days prior to registration * Diagnostic quality, cross sectional imaging of the thorax within 42 days prior to registration; 18-F-FDG-PET/CT or conventional CT are acceptable
  3. Age >= 18 years
  4. Patients must have a contraindication to cisplatin as defined in the following bullet points. Sites must complete the online tool at comogram.org prior to registration to determine if the patient is eligible. The scores must be recorded on a case report form (CRF). (Refer to data submission table on the NRG-HN008 protocol page on the NRG website); * Age >= 70 with moderate to severe comorbidity, defined as having one or more of the following conditions within 30 days prior to registration; ** Modified Charlson Comorbidity Index >= 1 ** Adult Comorbidity Evaluation (ACE)-27 Index >= 1 ** Omega score < 0.80 ** G-8 score =< 14 ** Cancer and Aging Research Group (CARG) Toxicity Score >= 30% ** Cumulative Illness Rating Scale for Geriatrics (CIRS-G) Score >= 4 OR * Age < 70 with severe comorbidity, defined as having two or more of the following conditions within 30 days prior to registration; ** Modified Charlson Comorbidity Index >= 1 ** ACE-27 Index >= 1 ** Omega score < 0.80 ** G-8 score =< 14 ** CARG Toxicity Score >= 30% ** CIRS-G Score >= 4 OR * Age >= 18 with an absolute or relative contraindication to cisplatin, defined as one or more of the following criterion within 30 days prior to registration: ** Pre-existing peripheral neuropathy grade >= 1; ** Creatinine clearance (CrCl) must be > 30 and < 60 mL/min *** For this calculation, use the Cockcroft-Gault formula ** History of hearing loss, defined as either: *** Existing need of a hearing aid OR *** >= 25 decibel shift over 2 contiguous frequencies on a pretreatment hearing test as clinically indicated
  5. Zubrod Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 within 30 days prior to registration
  6. Whole blood cell (WBC) >= 2000 cells/mm^3 (within 30 days prior to registration)
  7. Absolute neutrophil count (ANC) >= 1,500 cells/mm^3 (within 30 days prior to registration)
  8. Platelets >= 100,000 cells/mm^3 (within 30 days prior to registration)

Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level less than 40 mIU/mL

  17. Willing to use highly effective contraceptives for males and females of childbearing potential during therapy and for 12 weeks after the last dose of M3814 (peposertib); this inclusion is necessary because the treatment in this study may be significantly teratogenic
