A Phase II, Multicenter, Open Label Study to Evaluate Effectiveness and Safety of AdCMV-p53 Administered by Intra-Tumoral Injections in 39 Patients With Recurrent Squamous Cell Carcinoma of the Head and Neck (SCCHN)

Date de début de l'étude : 1 janvier 1998

DISEASE CHARACTERISTICS: Histologically proven squamous cell carcinoma of the head and neck (SCCHN) Recurrent disease documented by histology or cytology (excluding endolaryngeal recurrence) following first line therapy with curative intent, such as: Radiation (at least 5000 cGy by standard methodology) and/or Surgery (definitive resection with postoperative radiation as indicated) Lesions accessible to intratumoral injections Bidimensionally measurable disease The sum of the products of the bidirectional measurements for all bidimensionally measurable lesions must be not greater than 30 cm2 The sum of the longest diameters of all measurable lesions must be not greater than 10 cm No CNS metastasis Tumor tissue from biopsy of primary or recurrent tumor must be available to determine p53 mutation status PATIENT CHARACTERISTICS: Age: 18 and over Performance status: Karnofsky 60-100% Life expectancy: Greater than 12 weeks Hematopoietic: Platelet count at least 100,000/mm3 Absolute neutrophil count at least 2,000/mm3 Hepatic: Total bilirubin no greater than upper limit of normal (ULN) AST/SGOT and/or ALT/SGPT no greater than 1.5 times ULN Alkaline phosphatase no greater than 5 times ULN Renal: Not specified Other: Not pregnant or nursing Barrier contraception required during treatment Negative for HIV 1, HIV 2, hepatitis B, and hepatitis C At least 2 years since prior malignancy, other than SCCHN No contact with former tissue or organ transplant recipients or persons with severe immunodeficiency disease within 28 days following final dose of study drug No serious concurrent medical conditions No active uncontrolled infection PRIOR CONCURRENT THERAPY: Biologic therapy: No concurrent immunostimulating drugs No prior autologous or allogeneic organ or tissue transplant Chemotherapy: At least 4 weeks since prior chemotherapy At least 6 weeks since nitrosourea or mitomycin No other concurrent chemotherapy Endocrine therapy: No concurrent nontopical corticosteroids unless chronic (at least 6 months) at low doses (no greater than 10 mg of oral prednisone) Radiotherapy: See Disease Characteristics At least 4 weeks since radiotherapy to measurable disease sites, unless progressive disease No concurrent radiotherapy to disease sites receiving study drug injections Surgery: See Disease Characteristics No concurrent surgery to disease sites receiving study drug injections Other: No concurrent high dose steroids At least 4 weeks since experimental therapy No concurrent other experimental drugs or therapy No prior gene therapy using adenoviral vectors
