A Prospective Single Arm Non-inferiority Trial of Major Radiation Dose De-Escalation Concurrent With Chemotherapy for Human Papilloma Virus Associated Oropharyngeal Carcinoma (Major De-escalation to 30Gy for Select Human Papillomavirus Associated Oropharyngeal Carcinoma)
In Brief
A Phase 2 clinical trial evaluating F-FMISO PET/CT Scan, 30 Gy over 3 weeks, and 4 other interventions for HPV-Associated Oropharyngeal Squamous Cell Carcinoma and Squamous Cell Carcinoma of the Neck. Active but no longer recruiting, targeting 316 participants across 10 sites.
Detailed Summary
The purpose of this study is to demonstrate that participants with HPV positive and hypoxia negative T1-2, N1-2c (AJCC, 7th ed.) oropharyngeal squamous cell carcinoma receiving a major de-escalated radiation therapy with 2 cycles of standard chemotherapy is not inferior to comparable subjects treated with the current standard chemoradiation. Accrual for Cohort A has been completed. Cohort B is active and continues to enroll participants where surgery is optional and proton is allowed.
Study Details
Timeline
Interventions
All subjects on Cohort A and the first 100 subjects accrued to Cohort B will undergo a pre-treatment F-FMISO scan PET/CT scan pretreatment. For both Cohort A and Cohort B, FMISO scan will be repeated between the 5th-10th RT day if pre-treatment scan is hypoxic. If the repeat 18F-FMISOscan PET/CT demonstrates hypoxia, the subject will receive 70Gy concurrent with 2 cycles of chemotherapy. All subjects accrued onto Cohort B after 100 accruals will undergo only one 18F-FMISO scan done 5-10 treatment days after start of radiation therapy.
Treatment will be delivered as one fraction per day on a standard 5 day per week schedule (excluding weekends and holidays), total of 30 Gy over 3 weeks at 2 Gy per fraction each day. The gross nodes, the primary/postoperative bed if applicable, all subclinical areas at risk for disease will receive the same dose at 30Gy.
Cycle 1 (week 1): At the start of week 1 of IMRT, 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.
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). Cycle 2 (Week 4): After the three weeks of radiation at week 4 when the subject no longer is receiving radiation therapy, subjects will receive cisplatin 100 mg/m2 intravenously. The may be given for 2 consecutive days (50 mg/m2 each day for a total dose 100 mg/m2), typically on days 22 and 23, or as a single dose, typically on day 22.
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. 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).
Proton beam using pencil beam delivery either with the Varian or IBA delivery systems will be allowed for Cohort B. Proton beam therapy will be given at the New York Proton Center in New York City, where MSKCC has a well-established business associate agreement and cooperative research agreement with, respectively. If treatment at NYPC is not feasible, patients may be referred to ProCure in Somerset, NJ.
