A Study of Reduced Radiation Therapy and Standard-of-Care Chemotherapy in People With HPV-Positive Throat Cancer

Official title

Major Radiation Dose De-Escalation Concurrent With Chemotherapy for Human Papilloma Virus Associated Oropharyngeal Carcinoma

Overview

The purpose of this study is to find out if lower doses of radiation may help reduce the side effects of radiation therapy in combination with standard-of-care chemotherapy in people with HPV-positive throat cancer. The chemotherapy drugs used in this study include cisplatin, carboplatin, and 5-fluorouracil (5- FU), paclitaxel and abraxane- (Albumin-bound Paclitaxel).

Interventions

• Diagnostic test 18 F-FMISO PET/CT
  The 18F-FMISO PET/CT Scan Protocol consists first of an IV bolus injection of approximately 5-10 mCi of the radiotracer. At between 150-180 mins post injection, 18F-FMISO images will be acquired.
• Radiation Radiation
  Total Radiation Dose (over 3 weeks) 30Gy\*\* in 2 Gy per fraction
• Drug Cisplatin
  Concurrent chemotherapy (2 cycles) will be given. At the start of week 1 of radiation, subjects will receive cisplatin 100 mg/m2 intravenously. They may be given for 2 consecutive days (50 mg/m2 each day for a total dose 100 mg/m2 ), typically on days 1 and 2, or as a single dose, typically on day 1.
• Drug Carboplatin
  If cisplatin cannot be given at 100 mg/m2 for either cycle 1 or cycle 2, the investigator may use a regimen with carboplatin and 5-Fluorouracil in its place. Carboplatin will be given at a dose of AUC 1.25 intravenously daily x 4 days starting on day 1 of the cycle (total dose of AUC 5). 5-Fluorouracil will be given at a dose of 600 mg/m2 intravenous infusion over 24 hours daily x 4 days (total dose of 2400 mg/m2 intravenous infusion over 96 hours). (Cohort B to start carboplatin (AUC 1.5) and
• Drug 5-fluorouracil
  If cisplatin cannot be given at 100 mg/m2 for either cycle 1 or cycle 2, the investigator may use a regimen with carboplatin and 5-Fluorouracil in its place. Carboplatin will be given at a dose of AUC 1.25 intravenously daily x 4 days starting on day 1 of the cycle (total dose of AUC 5). 5-Fluorouracil will be given at a dose of 600 mg/m2 intravenous infusion over 24 hours daily x 4 days (total dose of 2400 mg/m2 intravenous infusion over 96 hours).

Primary outcome measures

• Number of participants with any locoregional recurrences [Time frame: 2 years]

Eligibility criteria

Inclusion criteria

• Pathologically (histologically or cytologically) proven diagnosis of HPV associated squamous cell carcinoma of the oropharynx (tonsil, base of tongue, or oropharyngeal walls) from biopsy, surgical resection or excisional biopsy regardless of margin status.

• Squamous cell carcinoma of the neck of unknown primary is allowed with excision biopsy of a lymph node (or core biopsy) or consent from the PI or co-PI
• Patient must have excisional biopsy or core biopsy done in order to be on protocol
• Subjects must have clinically or radiographically evident measurable gross disease at either the primary tumor site or nodal stations.
• Oropharyngeal Carcinoma (AJCC, 7th ed.) without evidence of distant metastasis based on FDG PET/CT.
• CT or MRI of the neck with and without contrast Note: A CT scan of neck and/or a PET/CT performed for the purposes of radiation planning may serve as planning tools.
• ECOG Performance Status of 0-2 or KPS ≥ 50
• Age ≥ 18 Patients over 70yrs will be able to enroll in Cohort B only).
• Adequate hematologic function within 30 days prior to registration, defined as follows:

• White Blood Count (WBC) ≥ 2 K/mcL
• Absolute neutrophil count (ANC) ≥ 1,000 cells/mm3
• Platelets ≥ 100,000 cells/mm3
• Hemoglobin ≥ 8.0 g/dl; Note: The use of transfusion or other intervention to achieve Hgb ≥ 8.0 g/dl is acceptable
• Adequate renal function within 30 days prior to registration, defined as follows:

• Serum creatinine < 1.5 mg/dl or creatinine clearance (CC) ≥ 50 ml/min determined by 24-hour collection or estimated by Cockcroft-Gault formula: CCr male = \[(140 - age) x (wt in kg)\] \[(Serum Cr mg/dl) x (72)\] CCr female = 0.85 x (CrCl male)

Note: Patients who cannot tolerate cisplatin or carboplatin/5FU based on clinical judgment will receive carboplatin and paclitaxel Paclitaxel can be substituted with Abraxane (Albumin-bound Paclitaxel).

• Adequate hepatic function within 30 days prior to registration, defined as follows:

• Bilirubin < 2 mg/dl
• AST or ALT < 3 x the upper limit of normal

Note: Exceptions can be made with PI and/or Co-Pi approval for patients to enroll on trial with a higher Bilirubin level such as Gilbert's Syndrome.

Note: Patients who cannot tolerate cisplatin or carboplatin/5FU based on clinical judgment will receive carboplatin and paclitaxel. Paclitaxel can be substituted with Abraxane (Albumin-bound Paclitaxel).

• Negative serum pregnancy test within 14 days prior to registration for women of childbearing potential
• The subject must provide study-specific informed consent prior to study entry
• Subject able to undergo MRI scans except for major medical contraindications like presence of a pacemaker or approved by the PI or the CO-PI that the subject does not need to undergo MRI scans

Exclusion criteria

• Subjects with prior head and neck radiation therapy
• Subjects with simultaneous primary cancers outside of the oropharynx

a. Note: Exceptions can be made for patients with simultaneous primaries outside the oropharynx if determined by the PI/Co-PI the patient can proceed with protocol activities.

• Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for 3 years or if cure rate from treatment at 5 years to be 90% or greater
• Prior systemic chemotherapy for the study cancer; note that prior chemotherapy for a different cancer is allowable
• Severe, active co-morbidity defined as follows: (exceptions can be made if approved by the PI and/or co-PI)
