Study Details

Study Description

Brief Summary

The study will evaluate whether adjuvant chemo-embolization increases progression free and/or overall survival relative to standard of care radiation and chemo- and/or immunotherapy in cisplatin-ineligible head and neck cancer patients with an acceptable morbidity rate.

Condition or Disease	Intervention/Treatment	Phase
SCCHN Squamous Cell Carcinoma	Drug: Cisplatin	Phase 2

Detailed Description

This is a single site, single arm Phase II trial pilot study to explore if chemo-embolization increases progression free and/or overall survival in a subpopulation of cisplatin-ineligible head and neck cancer patients with an acceptable morbidity rate in the U.S. Chemo-embolization will serve as adjuvant therapy performed in addition to standard of care radiation and chemo- and/or immunotherapy. Within UAB, the Investigators plan to recruit 48 patients to implement the intervention, within a two-year period. Progression free survival will be assessed at 3, 6 and 24 months (if available) after intervention, which is determined based upon the results of follow-up Head and Neck imaging (CT or MRI) interpreted by a Radiologist not involved in the study, per standard of care. Overall survival will be reported by the patients' Oncology team on a monthly basis. The trial endpoints will form the basis of how PFS and OS compare to historical outcomes in a similar cohort of patients.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Chemo-embolization Intra-arterial Cisplatin suspension 150-300 mg is infused into the tumor pedicle(s)	Drug: Cisplatin Subjects will be admitted to the UAB Heart and Vascular Center, pre-medicated with 24 mg Ondansetron IV, 500 mg Prednisolone IV and 1.5 L NaCl with 20 meq KCl IV. The chemo-embolic agent is prepared in the HVC pharmacy by reconstituting 300 mg lyophilized Cisplatin in 60 mL 0.9% NaCl. Subjects are placed under anesthesia in the angiography suite. The access site is prepped and draped in sterile fashion then the femoral artery is catheterized using a 5-French catheter containing a coaxial microcatheter. After superselective visualization of the tumor-feeding vessel, a microcatheter is advanced into the target vessel and infused with 150 mg m2 cisplatin in 45-60 mL NaCl over 30-60 seconds. 10 seconds after the infusion starts, 9 gm sodium thiosulphate is administered IV to neutralize systemic Cisplatin. A post-infusion angiogram is then performed to assess the adequacy of embolization. The catheter is removed and the arteriotomy site closed with a subcutaneous suture. Other Names: Platinol

Outcome Measures

Primary Outcome Measures

Evaluate progression free survival [6 Months]
Progression free survival is the length of time from the day of the chemo-embolization procedure that a patient lives with the disease but it does not get worse. Cumulative progression-free survival for all patients will be calculated by the Kaplan-Meier method, including the point estimates of progression-free survival and the 95% confidence intervals, evaluated during a six-month period of follow-up.

Secondary Outcome Measures

Evaluate overall survival [2 Years]
Although the overall survival is related to the primary endpoint (progression free survival), it will be measured independent of the progression free survival. Overall survival is defined for all patients and measured from time of treatment to death or end of a study.
Evaluate oropharyngeal bleeding [2 years]
Physician visits prompted by new oropharyngeal bleeding that occurs after chemo-embolization will be tabulated. Cumulative bleed-free survival for all patients will be calculated by the Kaplan-Meier method, including the point estimates of bleed-free survival and the 95% confidence intervals, evaluated during a six-month period of follow-up.
