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

Brief Summary:

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.

Design:

  • 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.

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.

ELIGIBILITY:

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