Safety and Efficacy of Repeat Administration of Ad/PNP and Fludarabine Phosphate in Patients With Local Head/Neck Cancer

Korábbi kezelés

• Prior history or current diagnosis of leukemia
• Have received any gene therapy products or oncolytic viral therapy
• Receiving allopurinol
• Received an investigational drug within 30 days prior to first injection of Ad/PNP
• Received radiation treatment \< 4 weeks prior to first injection of Ad/PNP, and does not have any RECIST 1.1 evaluable lesions that are outside the radiation field. (If the patient has RECIST 1.1 evaluable lesions outside the radiation field then they can be included.)
• Received chemotherapy (systemic anticancer treatment) \< 4 weeks prior to first injection of Ad/PNP and has not recovered from all the related side effects. (If the patient has recovered from all related side effects or has reached a new baseline, then they may begin receiving treatment at sooner than 4 weeks)
• Had within 6 months prior to enrollment: Myocardial infarction, cerebral vascular accident, uncontrolled congestive heart failure, significant liver disease, unstable angina
• Receiving chronic systemic corticosteroids (\> 3 weeks) or any chronic immunosuppressive medications within 14 days prior to first injection of Ad/PNP. Subjects receiving short courses of corticosteroids are considered eligible for the study.
• Receiving anticoagulants other than those to maintain patency of venous lines

Más betegség

• Uncontrolled intercurrent disease (e.g., diabetes, hypertension, thyroid disease, active infection)
• History of HIV infection. No requirement for testing.

Egyéb

• Have significant baseline neuropathy (\> Grade 2 based on Common Terminology Criteria for Adverse events \[CTCAE\] v5.0)
• Fever (temperature \> 38.1 degrees C orally)
• Women who are pregnant or breast feeding

• Provided Informed Consent
• Age ≥ 18 years
• Patients with histologically or cytologically confirmed diagnosis of recurrent cancer of the head and neck region for whom there is no curative treatment option. For the purposes of trial eligibility, cancers of the head and neck shall include, in addition to head and neck squamous cell carcinoma (HNSCC), cutaneous squamous cell primary sites and squamous cell carcinoma of unknown primary presenting with neck lymph nodal disease, as well as nasopharyngeal carcinoma, and salivary gland tumors.
• All standard or approved treatment options that would provide substantive palliation must have failed, been exhausted, or patient not eligible or willing to use them (for example neuropathy, nephropathy , or hearing loss precluding the use of cisplatin)
• Tumor mass (primary tumor and/or lymphadenopathy) measurable by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and technically suitable for intratumoral injections (otolaryngologist will determine feasibility). Patients with nodal disease (or metastatic disease) that is needle accessible are eligible. Patients with additional tumors (including distant metastatic disease) beyond the intratumoral injection accessible tumor(s) that are not accessible for intratumoral injection are eligible ONLY if the patient has no other treatment option for the metastatic disease and treatment of local disease may provide the patient some benefit or palliation.
• Eastern Cooperative Oncology Group performance status of ≤ 2
• In the judgment of the Investigator, the patient has recovered sufficiently from any previous significant therapy side effects or toxicities prior to Ad/PNP administration.
• Absolute neutrophil count ≥ 1,500 cells/ul; hemoglobin ≥ 9 g/dl, platelets ≥ 100,000/ul
• Serum creatinine ≤ 1.5 mg/dl, or calculated creatinine clearance ≥ 60 ml/min
• Bilirubin ≤ upper limit of normal, alanine aminotransferase ≤ 1.5 x upper limit of normal and/or aspartate aminotransferase ≤ 1.5 x upper limit of normal, alkaline phosphatase ≤ 2.5 x upper limit of normal
• Prothrombin time (PT)/international normalized ratio (INR) ≤ 1.5 x upper limit of normal
• Activated partial thromboplastin (aPTT) time ≤ 1.5 x upper limit of normal
• Female patients must have a negative urine or serum pregnancy at screening (pregnancy test is not required for patients with bilateral oophorectomy and/or hysterectomy or for those patients who are \> 1 year postmenopausal)
• All patients of reproductive potential must agree to use a medically acceptable form of contraception (eg, hormonal birth control, double-barrier method) or abstinence.
