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

A Phase 1 Study to Assess the Feasibility and Safety of Tumor HPV-E6/E7-Targeting T Cell Suspension for Intravenous Infusion (HPV-T) in Patients With HPV-16 Positive Recurrent or Metastatic Solid Tumor

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.

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.

Inclusion Criteria:

1. Greater than or equal to 18 years of age and less than or equal to 75 years of age; all genders.
2. Confirmed diagnosis of recurrent of metastatic solid tumor and at least one measurable lesion.

9. Patients who are able to cooperate to observe adverse reactions and the effect of the treatment,expected lifetime is greater than six month.
10. Patients of both genders must be willing to practice birth control from the time of enrollment to three months after treatment on this study,a fertile woman must have a negative pregnancy test.
11. The laboratory test values and the functions of important organs meet the following requirements:

1#Serology: HIV antibody(-), hepatitis B DNA(-), hepatitis C antibody(-) and no active syphilis infection; 2#Hematology: Absolute neutrophil count is greater than or equal to 1.5×10^9/L; WBC is greater than or equal to 3×10^9/L; lymphocyte count is greater than or equal to 0.8×10^9/L; Platelet count is greater than or equal to 100×10^9/L; Hemoglobin is greater than or equal to 85g/L ; 3#Chemistry: Serum ALT/AST is less than or equal to 3 times ULN,except in patients with liver metastasis who must have ALT/AST less than or equal to 5 times ULN; Serum Creatinine is less than or equal to 1.5 times ULN ; Total bilirubin is less than or equal to 1.5 times ULN, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3 times ULN; 4#Blood Clotting Parameters:Prothrombin Time(PT) and International Normalised Ratio (INR) are less than or equal to 1.5 times ULN;Activated Partial Thromboplastin Time (APTT) is less than or equal to 1.5 times ULN;For subjects who frequently take anticoagulant drugs,their blood clotting parameters can meet the value range adoptive to this special population; 5#Left ventricular ejection fraction#LVEF#is more than or equal to 50%. 12. More than four weeks must have elapsed since any prior systemic therapy (except for bridging therapy) at the time the patient receives the lymphodepletion regimen, and toxicities must have recovered to grade 1 or less (except for toxicities such as alopecia or vitiligo)

Exclusion Criteria:

1. Pregnant or lactating women.
2. History of severe immediate hypersensitivity reaction to HPV-T and any of the agents used in this study.
3. Participants with a history of organ transplantation.
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.
7. Severe liver and kidney function damage(given treatment is still uncontrollable, and biochemical indicators cannot meet the Exclusion Criteria of 11th), uncontrollable diabetes, pulmonary fibrosis, interstitial lung disease, acute lung disease, or poorly controlled hypertension (systolic pressure>160mmHg and/or diastolic pressure>90mmHg); active cardiovascular and cerebrovascular diseases, such as acute stroke, myocardial infarction, unstable angina, congestive heart failure rated as Grade II or above by the New York Heart Association, severe cardiac arrhythmias that cannot be controlled with medication, electrocardiograms show significant abnormalities (three consecutive times with an interval of at least 5 minutes) which have been assessed by the investigator that affect subsequent cellular treatment; mental illness and drug abuse, or any situation that the investigator assessments may increase the risk of this study.
8. Participants plan to receive glucocorticoid (the dose of prednisone or alternative drug is more than 10mg per day) or other immunosuppressant within 4 weeks before the administration of lymphocyte clearance. Tips: when there is no active autoimmune disease, it is allowed to use prednisone or alternative drug with a dose less than 10 mg per day; Allowing participants to use topical, ocular, intra articular, intranasal, and inhaled glucocorticoids for treatment.
9. Participants plan to receive immunomodulatory drugs (such as interferon, GM-CSF, thymosin, gamma globulin, excluding IL-2) within 4 weeks before the administration of lymphocyte clearance.
10. The investigator assessed that the subject was unable or unwilling to comply with the requirements of the study protocol.
11. With a history of other malignant tumors.
12. The participant has any disease or medical condition that may affect the safety or effectiveness evaluation of the study treatment.
