About this study

Official title: A Phase I/II Clinical Trail of TC-E202 Targeting HPV16 E6 for Relapsed/Refractory to Standard Treatment or Metastatic Cervical Carcinoma

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.

Read the detailed description

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. T cells genetically engineered with a TCR targeting HPV-16 E6 (E6 TCR) display specific reactivity against HLA-A2+, HPV-16+ target cells.

T cell receptor (TCR) gene engineered T cells infusion can induce objective tumor responses in certain malignancies including HPV-16+ cancer.

Objective:

Phase I: Determine the safety and tolerability of TC-E202 inHPV16 positive patients with relapsed/refractory to standard treatment or metastatic cervical carcinoma and determine the Recommended Phase II Dose (RPIID).

Primary endpoints: safety and tolerability. The evaluation of safety and tolerability will be based on the following endpoints: 1) Whether DLT occurs or MTD is achieved; 2) The incidence of various adverse events and serious adverse events and their relationship with TCR-T, IL-2, lymphodepletion chemotherapy and leukapheresis.

Secondary endpoints: efficacy. Objective response rate (ORR), duration of response (DOR), progression-free survival (PFS), and overall survival (OS) were assessed based on RECIST 1.1 and iRECIST.

Eligibility:

Adults aging 18-70 with relapsed/refractory to standard treatment or metastatic cervical carcinoma.

Eligible patients were HLA-A*02 and had metastatic HPV16-positive cervical cancer. Patients had received or declined previous systemic therapy, with more than 4 weeks elapsed since previous systemic treatment. Patients had an Eastern Cooperative Oncology Group performance score of 0 or 1 and adequate hematologic, hepatic, and renal function.

Design:

This is a Phase I/II clinical trial to evaluate the efficacy and safety of TC-E202.

Dose escalation will proceed according to 3+3 procedure. All patients will receive a lymphocyte-depleting preparative regimen of cyclophosphamide and fludarabine followed by an infusion of E6 TCR (TC-E202) cells. Cell infusion will be followed by IL-2 administration.

All patents will be evaluated based on ORR according to RECIST v1.1\&iRECIST. Phase I clinical trials establish a Drug Safety Review Committee (SRC), and the SRC will hold regular and irregular meetings to evaluate the safety data of the subjects, the clinical pharmacology, along with associated clinical efficacy, to decide escalating dose and RPIID. In addition, the SRC will decide whether to explore higher or lower doses than planned doses based on specific data.

Study groups in NCT05357027
Study groupRoleWhat they receive
TC-E202 doseExperimentalThis 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.
Receives: Biological: TC-E202 cells; Drug: IL-2; Drug: Fludarabine; Drug: Cyclophosphamide Capsules

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Dose Limiting Toxicity or Maximum Tolerated Dose (MTD)

    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.

    Measured: Day 28 after the first TC-E202 infusion

  2. Overall response rate

    The efficacy of TC-E202 will be assessed by the objective response rate (ORR) is evaluated according to RECIST 1.1 and iRECIST. ORR is described as patients assessed with partial response (PR) and complete response (CR).

    Measured: Day0-Day730

  3. Treatment-related adverse events as assessed by CTCAE v5.0

    The type, incidence and severity of adverse events include abnormal laboratory examination results with clinical significance after treatment, abnormal physical examination and blood examination results, bone marrow examination results, etc. Clinical and laboratory adverse events will be classified according to the National Cancer Institute general terminology standard for adverse events (NCI CTCAE) version 5.0.

    Measured: Day0-Day730

Secondary outcomes (7)
  1. Duration of response

    The efficacy of TC-E202 will be assessed by duration of response (DOR). The DOR refers to the length of time from the first appearance of a treatment response to the first occurrence of progressive disease or recurrence.

    Measured: Day0-Day730

  2. Progression free survival

    The efficacy of TC-E202 will be assessed by progression free survival (PFS). The PFS refers to the time from treatment to progressive disease or death for any reason.

    Measured: Day0-Day730

  3. Overall survival

    The efficacy of TC-E202 will be assessed by overall survival (OS). The OS refers to the time from treatment to death.

    Measured: Day0-Day730

  4. Maximum Persistence (Cmax) of TC-E202

    Blood samples were collected to measure persistence of infused TC-E202 using polymerase chain reaction of a vector specific sequence in deoxyribonucleic acid (DNA) extracted from peripheral blood mononuclear cell (PBMC).

    Measured: Day0-Day730

  5. Time to Maximum Persistence

    Blood samples were collected to measure persistence of infused TC-E202 using polymerase chain reaction of a vector specific sequence in DNA extracted from PBMC.

    Measured: Day0-Day730

  6. Area Under the Plasma Concentration-time Curve From Zero to Day 28 (AUC[0-28])

    Blood samples were collected to measure persistence of infused TC-E202 using polymerase chain reaction of a vector specific sequence in DNA extracted from PBMC.

    Measured: Day 28 after the first TC-E202 infusion

  7. Anti-PD-1 single chain antibody concentration

    The pharmacodynamics of TC-E202 will be assessed by Anti-PD-1 single chain antibody content.

    Measured: Day0-Day730
