Summary

The purpose of this study is to establish the efficacy and toxicity of low dose chemoradiotherapy after induction chemotherapy in patients with locally advanced HPV+ oropharynx cancer and establish prognostic factors that would apply to help select patients for this treatment in the future.

Description

In general, patients with Human Papilloma Virus Oropharynx Cancer (HPVOPC) are young and will live for prolonged periods. They are at high risk for long-term toxicity and mortality from radiotherapy. While the long-term consequences of chemotherapy for head and neck cancer are relatively constrained, high-dose radiotherapy (RT) and chemoradiotherapy (CRT) substantially impact on local tissues and organ function and result in a significant rate of late mortality and morbidity in patients. Studies are now being designed to reduce the impact of RT and CRT for patients. Identifying appropriate endpoints and study arms which will allow an early assessment of outcomes will be problematic, particularly for equivalence studies wherein survival differences are small, and where prolonged time periods and large patient numbers are necessary to accurately assess outcomes. For Sequential Therapy as given with TAX 324, 3-year PFS may be an appropriate endpoint. The same may not be possible for CRT. The best example of changing outcomes in CRT trials would be R91-11, in which a premature negative conclusion regarding the efficacy of induction therapy was published with the early analysis. Late toxicity and morbidity, a hallmark of upfront cisplatin-based CRT trials, led to equivalence between induction therapy and CRT for laryngectomy-free survival at 5 years, and more importantly a non-significant relative 10% improvement in overall survival in the PF induction arm compared to the CRT arm which included an every 3-week bolus cisplatin for 3 cycles during radiotherapy.

The survival results in HPVOPC achieved in TAX 324 and preliminary data from ECOG 1308 strongly suggest that it might be possible to reduce long-term morbidity in HPVOPC and preserve survival perhaps by better patient selection and by reducing radiotherapy intensity in the context of ST for more advanced cases. Best approach of HPV-negative disease might be with novel therapies and more aggressive Sequential Therapy (ST) or CRT.

Current radiation dose reduction trials are under way in ECOG, RTOG and other radiation based groups. The data from TAX 324 suggest that it is possible to reduce the radiation dose because of the superior progression free survival and the ability to select risk based CRT.

Eligibility

Yes No Not Sure

Inclusion Criteria

Participants must meet the following criteria to be eligible to participate in
the study. Patients may enroll in the study if they meet all of the entry
criteria, were candidates for induction chemotherapy regardless of HPV status
and have to start therapy for logistic reasons prior to p16 and HPV testing
They will enter the experimental post-Induction portion of the study if the
surgical specimens or biopsies are proven to be HPV+ on PCR testing. Patients
who are HPV negative will be taken off study and treated with SOC radiotherapy
and surgery
Participants must have histologically or cytologically confirmed squamous cell carcinoma of the oropharynx, hypopharynx, supraglottic larynx, nasal cavity, unknown primary, or nasopharynx that is p16 and HPV positive. Tissue from the primary site or lymph node must be available for biomarker studies and for PCR testing. IHC must be performed in a lab verified by the central laboratory or the slides must be available for review by the central laboratory and PCR must be done in the central laboratory prior to radiotherapy. HPVPCR must be performed and results available for reduced dose therapy after induction
Patients who are on the Quarterback Trial when Quarterback 2 is activated and who have been randomized to radiotherapy arm will be asked to transfer to this trial and receive the Quarterback 2 defined radiotherapy
Stage 3 or 4 disease without evidence of distant metastases
At least one clinically evaluable or uni- or bi-dimensionally measurable lesion by RECIST 1.1 criteria
Age 18 years
No previous surgery, radiation therapy or chemotherapy for SSCHN (other than biopsy or tonsillectomy) is allowed at time of study entry
ECOG performance status of 0 or 1
No active alcohol addiction (as assessed by medical caregiver and defined as at least 6 months without activity)
Participants must have adequate bone marrow, hepatic and renal functions as defined
below
\- Hematology
\- Neutrophil count 1.5 x 10^9/l
\- Platelet count 100 x 10^9/l
\- Hemoglobin 10g/dl
\- Renal function 60 ml/min (actual or calculated by the Cockcroft-Gault method) as follows: CrCl (ml/min) = (140-age)(weight kg)/(mL/min) / 72 x serum creatinine (mg/dL)
\- N.B. For females, use 85% of calculated CrCl value. Or a Creatinine the upper limits of normal
\- Hepatic
\- Total Bilirubin institutional upper level of normal (ULN)
\- AST or ALT and Alkaline Phosphatase must be within the range allowing for eligibility
Women of childbearing potential must have a negative pregnancy test within 7 days of starting treatment
Ability to understand and the willingness to sign a written informed consent document
Patients with Gilbert's Disease and absent hepatic pathology by history and clinical assessment may be treated on study with bilirubin > the ULN for the institution if other liver functions studies are within the normal range

Exclusion Criteria

Pregnant or breast feeding women, or women and men of childbearing potential not willing to use adequate contraception while on treatment and for at least 3 months thereafter
Previous or current malignancies at other sites, with the exception of adequately treated in situ carcinoma of the cervix, basal or squamous cell carcinoma of the skin, thyroid cancer, or other cancer curatively treated by surgery and with no current evidence of disease for at least 5 years
Symptomatic peripheral neuropathy grade > 2 by NCI Common Terminology Criteria (NCI-CTC) version 4
Symptomatic altered hearing > grade 2 by NCI-CTCv4 criteria.These patients can be entered by substituting carboplatin for cisplatin with an AUC of 6.0

\- Autoimmune disease requiring therapy, prior organ transplant, or HIV infection
\- Interstitial lung disease
\- Hepatitis C by history, and confirmed by serology
Patients that have experienced an involuntary weight loss of more than 25% of their body weight in the 2 months preceding study entry
Concurrent treatment with any other anticancer therapy
Participation in an investigational therapeutic drug trial within 30 days of study entry
Active smoking or a cumulative pack year history of > 20 pack years, active smoking is (Defined as 1 cigarette per day) within the last 5 years
