HPV-T in HPV-16 Positive Recurrent or Metastatic Solid Tumors

Overview

The purpose of this protocol is to evaluate the feasibility and safety of HPV-T in HPV 16 positive recurrent or metastatic solid tumor patients.

Description

In this study, HPV-T cells will be cultured from mononuclear cells collected from participant's peripheral blood in the laboratory and they will be given back to the participant intravenously. The use of HPV-T cells involves a combination of IL-2, which is a drug used to help the body's response to treatment on the immune system. A medium dose regimen of IL-2 will be given after the participant receives the infusion of the T-cells.

Each HPV-T cell reinfusion is a treatment cycle, and each participant will receive a maximum of four cycles of HPV-T treatment. Whether the participant receives the next cycle of treatment depends on the efficacy of the previous HPV-T treatment, which is assessed by imaging.

          4. Participants with brain metastases.
          5. Any active autoimmune disease or participants with a history of autoimmune diseases
             that have been assessed by the investigator to be unsuitable for this study. Including
             but not limited to the following diseases: such as systemic lupus erythematosus,
             immune related neuropathy, multiple sclerosis, Guillain Barre syndrome, myasthenia
             gravis, connective tissue diseases, inflammatory bowel diseases(Crohn's disease and
             ulcerative colitis), excluding vitiligo, eczema, type I diabetes, rheumatoid arthritis
             and other joint diseases, Sjogren's syndrome and controlled psoriasis by local
             medication.
          6. Active systemic infections, for example, acute infections requiring systemic
             antibiotic, antiviral, or antifungal treatment occur within 2 weeks before enrollment.

             biochemical indicators cannot meet the Exclusion Criteria of 11th), uncontrollable
             diabetes, pulmonary fibrosis, interstitial lung disease, acute lung disease, or poorly
