Background: The NCI Surgery Branch has developed an experimental therapy for treating patients with cancer that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying these specific cells with a type of virus (retrovirus) to attack only the tumor cells, and then giving the cells back to the patient. This type of therapy is called gene transfer. Researchers want to test this on human papilloma virus (HPV)-associated cancers. Objective:

- The purpose of this study is to determine a safe number of these cells to infuse and to

see if these particular tumor-fighting cells (Anti-HPV E6) can shrink tumors associated with HPV and test the toxicity of this treatment. Eligibility:

- Adults age 18-66 with an HPV-16-associated cancer.


- Work up stage: Patients will be seen as an outpatient at the NIH clinical Center and

undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed

- Leukapheresis: If the patients meet all of the requirements for the study they will

undergo leukapheresis to obtain white blood cells to make the anti HPV E6 cells. {Leukapheresis is a common procedure, which removes only the white blood cells from the patient.}

- Treatment: Once their cells have grown, the patients will be admitted to the hospital

for the conditioning chemotherapy, the anti HPV E6 cells and aldesleukin. They will stay in the hospital for about 4 weeks for the treatment. Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits take up to 2 days.

Clinical Details

Official title: A Phase I/II Study of T Cell Receptor Gene Therapy Targeting HPV-16 E6 for HPV-Associated Cancers

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: To determine the objective tumor response rate and duration in patients with metastatic or recurrent/refractory HPV-16+ cancers treated with autologous T cells expressing the E6 TCR plus aldesleukin following a lymphocyte-depleting preparative r...

Detailed description: BACKGROUND:

- Metastatic or refractory/recurrent human papillomavirus (HPV)-16+ cancers (cervical,

vulvar, vaginal, penile, anal, and oropharyngeal cancers) are incurable and poorly palliated by standard therapies.

- HPV-16+ cancers constitutively express the HPV-16 E6 oncoprotein, which is absent from

healthy human tissues.

- Administration of T cell receptor (TCR) gene engineered T cells can induce objective

tumor responses in certain malignancies.

- T cells genetically engineered with a TCR targeting HPV-16 E6 (E6 TCR) display specific

reactivity against HLA-A2+, HPV-16+ target cells. OBJECTIVES: Primary Objective

- To determine a safe dose of administration of autologous T cells transduced with an

anti-HPV-16 E6 TCR and aldesleukin to patients following a nonmyeloablative but lymphodepleting preparative regimen.

- To determine the objective tumor response rate (Complete or Partial Response) and

duration in patients with metastatic or recurrent/refractory HPV-16+ cancers treated with this regimen. Secondary Objective(s)

- To determine the toxicity of this treatment regimen.

- To study immunologic correlates associated with E6 TCR gene therapy for HPV16+ cancers.


- Patients greater than or equal to 18 years old and less than or equal to 70 years old

with metastatic or refractory/recurrent HPV-16+ cancer.

- Prior first line systemic therapy is required unless the patient declines standard


- Patients must be HLA-A 02: 01-positive.


- Patients will receive a non-myeloablative lymphocyte-depleting preparative regimen of

cyclophosphamide and fludarabine

- On day 0 patients will receive transduced lymphocytes and then begin high dose


- The study will begin with a phase I dose escalation. After the MTD cell dose has been

determined, the patients will be enrolled into the phase II portion of the study.

- Clinical and immunologic response will be evaluated about 4 to 6 weeks after treatment

and then about every 1-6 months until disease progression

- Following a dose escalation phase of 9 to 18 patients, initially 21 evaluable patients

will be enrolled in the phase II portion of the study. If 0 to 1 of the 21 patients experiences a clinical response, then no further patients will be enrolled. If 2 or more of the first 21 evaluable patients enrolled have a clinical response, then accrual will continue until a total of 41 evaluable patients have been enrolled. The accrual ceiling will be set at 61 patients. Provided that about 1 patient every 6 weeks will be enrolled onto this trial, approximately 4 years may be needed to accrue the maximum number of patients.


Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.



1. Measurable metastatic or refractory/recurrent HPV-16+ cancer (determined by in situ hybridization (ISH) or a polymerase chain reaction (PCR)-based test). 2. Patients must be HLA-A 02: 01-positive. 3. All patients must have received prior first line standard therapy or declined standard therapy, and have been either non-responders (progressive disease) or have recurred. 4. Patients with 3 or fewer brain metastases that are less than 1 cm in diameter and asymptomatic are eligible. Lesions that have been treated with stereotactic radiosurgery must be clinically stable for 1 month after treatment for the patient to be eligible. Patients with surgically resected brain metastases are eligible. 5. Greater than or equal to 18 years of age and less than or equal to 70 years of age. 6. Able to understand and sign the Informed Consent Document. 7. Willing to sign durable power of attorney 8. Clinical performance status of ECOG 0 or 1. 9. Life expectancy of greater than 3 months. 10. Patients of both genders must be willing to practice birth control from the time of enrollment on this study up to 4 months after treatment. Patients must be willing to undergo testing for HPV-16 prior to becoming pregnant. 11. Women of child bearing potential must have a negative pregnancy test because of the potentially dangerous effects of the treatment on the fetus. 12. Serology:

- Seronegative for HIV antibody. (The experimental treatment being evaluated in

this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immune-competence and thus are less responsive to the experimental treatment and more susceptible to its toxicities.)

- Seronegative for hepatitis B antigen, and seronegative for hepatitis C antibody.

If hepatitis C antibody test is positive, then the patient must be tested for the presence of antigen by RT-PCR and be HCV RNA negative. 13. Hematology:

- Absolute neutrophil count greater than 1000/mm3 without the support of


- WBC greater than or equal to 3000/mm3

- Platelet count greater than or equal 100,000/mm3

- Hemoglobin greater than 8. 0 g/dL

14. Chemistry:

- Serum ALT/AST less than or equal to 2. 5 times the upper limit of normal

- Serum creatinine less than or equal to 1. 6 mg/dL

- Total bilirubin less than or equal to to 1. 5 mg/dL, except in patients with

Gilbert s Syndrome who must have a total bilirubin less than 3. 0 mg/dL 15. More than 4 weeks must have elapsed since any prior systemic therapy at the time the patient receives the preparative regimen. EXCLUSION CRITERIA: 1. Women of childbearing potential who are pregnant or breastfeeding. There are potentially dangerous side effects of the treatment on the fetus or infant. 2. Active systemic infections (for e. g.: requiring anti-infective treatment), coagulation disorders or other active major medical illnesses of the cardiovascular, respiratory or immune system, as evidenced by a positive stress thallium or comparable test, myocardial infarction, cardiac arrhythmias, obstructive or restrictive pulmonary disease. 3. Any form of primary immunodeficiency (such as Severe Combined Immunodeficiency Disease). 4. Concurrent opportunistic infections (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who have decreased immune competence may be less responsive to the experimental treatment and more susceptible to its toxicities). 5. Concurrent systemic steroid therapy. 6. History of severe immediate hypersensitivity reaction to cyclophosphamide or fludarabine. 7. History of coronary revascularization or ischemic symptoms. 8. Documented LVEF of less than or equal to 45% tested. The following patients will undergo cardiac evaluations a. clinically significant atrial and/or ventricular arrhythmias including but not limited to: atrial fibrillation, ventricular tachycardia, second or third degree heart block or b. age greater than or equal 60 years old
