Summary
Brief summary (as posted)
Background: Cervical cancer is the most common gynecologic malignant tumor. The occurrence and progression of cervical carcinoma is firmly relevant to HPV (Human papilloma virus) infection. Cancer cells infected by HPV expressing an HPV protein called E6. E6 is the main factors of HPV 16 carcinogenesis. In TCR-T therapy, researchers take the blood of a certain patient, select T cells and insert genes into the cell that expressing a kind of protein that targeting HPV E6. The genetically engineered cells are called E6 TCR-T cells. The engineered cells are re-infused in the patients with cervical carcinoma. Objective: To evaluate the safety and efficacy of TCR-T cells in the treatment of cervical carcinoma. Eligibility: Adults aging 18-70 with relapsed/refractory to standard treatment or metastatic cervical carcinoma. Design: Patients will have many screening tests, including imaging procedures, heart and lung tests, and lab tests. Patients will have leukapheresis. Blood will be removed through a needle in the arm. A machine separates the white blood cells. The rest of the blood is returned through a needle in the other arm. Engineered T cells will be re-infused into the patients will stay in hospital and be evaluated.

- TC-E202 dose
- description
- This study uses the "3+3" dose escalation method. The initial dose is Dose1, the maximum dose that patients can tolerate is determined as the phase II recommended dose (RPIID), and at least 6 patients are receiving RPIID treatment . If patients develop intolerance in Dose 1 (≥3 subjects with DLT), then the subsequent enrolled patients will receive Dose-1 infusion.

Primary outcomes (3)
- measure
- Dose Limiting Toxicity or Maximum Tolerated Dose (MTD)
- timeFrame
- Day 28 after the first TC-E202 infusion
- description
- Dose Limiting Toxicity (DLT) is defined as patients with the adverse event (AE) or laboratory abnormality recognized by SRC, and should be possibly related to TC-E202 cell therapy, and should be unrelated to the disease itself, disease progression, concomitant diseases or concomitant medication. The MTD is the highest dose at which ≤1 of 6 patients experienced a dose limiting toxicity (DLT) or the highest dose level studied if DLTs are not observed at any of the dose levels.
