Excessive activated T-cell proliferation after anti-CD19 CAR T-cell therapy.

Excessive activated T-cell proliferation was observed in vivo in one patient after an anti-CD19-chimeric antigen receptor (CAR) T-cell infusion. The patient, who had chemotherapy refractory and CD19 diffuse large B-cell lymphoma (DLBCL), received an anti-CD19 CAR T-cell infusion following conditioning chemotherapy (fludarabine/cyclophosphamide). The lymphocyte count in the peripheral blood (PB) increased to 77 × 10/L on day 13 post infusion, and the proportion of CD8 actived T cells was 93.

Cocktail treatment with EGFR-specific and CD133-specific chimeric antigen receptor-modified T cells in a patient with advanced cholangiocarcinoma.

Background: Cholangiocarcinoma (CCA) is one of the most fatal malignant tumors with increasing incidence, mortality, and insensitivity to traditional chemo-radiotherapy and targeted therapy. Chimeric antigen receptor-modified T cell (CART) immunotherapy represents a novel strategy for the management of many malignancies. However, the potential of CART therapy in treating advanced unresectable/metastatic CCA is uncharted so far.

Autologous T Cells Expressing CD30 Chimeric Antigen Receptors for Relapsed or Refractory Hodgkin Lymphoma: An Open-Label Phase I Trial.

Relapsed or refractory Hodgkin lymphoma is a challenge for medical oncologists because of poor overall survival. We aimed to assess the feasibility, safety, and efficacy of CD30-targeting CAR T cells in patients with progressive relapsed or refractory Hodgkin lymphoma. Patients with relapsed or refractory Hodgkin lymphoma received a conditioning chemotherapy followed by the CART-30 cell infusion.

Treatment of CD20-directed Chimeric Antigen Receptor-modified T cells in patients with relapsed or refractory B-cell non-Hodgkin lymphoma: an early phase IIa trial report.

Patients with relapsed or refractory non-Hodgkin lymphoma have a dismal prognosis. Chimeric Antigen Receptor (CAR)-modified T cells (CART cells) that targeted CD20 were effective in a phase I clinical trial for patients with advanced B-cell lymphomas. We performed a phase IIa trial to further assess the safety and efficacy of administering autologous anti-CD20 CART (CART-20) cells to patients with refractory or relapsed CD20 B-cell lymphoma.

Effective response and delayed toxicities of refractory advanced diffuse large B-cell lymphoma treated by CD20-directed chimeric antigen receptor-modified T cells.

We conducted a trial testing a CD20-specific CAR coupled with CD137 and the CD3ζ moiety in patients with chemotherapy refractory advanced diffuse large B cell lymphomas (DLBCL). Seven patients were enrolled. One of the two patients with no bulky tumor obtained a 14-month durable and ongoing complete remission by cell infusion only, and another attained a 6-month tumor regression.

CIK cells from recurrent or refractory AML patients can be efficiently expanded in vitro and used for reduction of leukemic blasts in vivo.

Autologous cytokine-induced killer (CIK) cell transfusion may prevent tumor relapse in acute myeloid leukemia (AML). This study investigated whether CIK cells from recurrent or refractory AML patients with high peripheral leukemia cell burdens could be expanded to a clinically usable number, and it further evaluated the antitumor potentials in vitro and in vivo. The numbers and phenotypes of CIK cells expanded from nine AML patients and 10 healthy donors were compared.

Repeated transfusions of autologous cytokine-induced killer cells for treatment of haematological malignancies in elderly patients: a pilot clinical trial.

The elderly population is susceptible to haematological malignancies, and these elderly patients are intolerant to cytotoxic drugs. Therefore, the exploration of a safe and reliable strategy exclusive of chemotherapy is critical in improving the prognosis of elderly patients with haematological malignancies. We evaluated the safety and the efficacy of autologous cytokine-induced killer (CIK) cells combined with recombinant human interleukin 2 (rhIL-2) in the treatment of haematological malignancies in elderly patients.

Clinical study of autologous cytokine-induced killer cells for the treatment of elderly patients with diffuse large B-cell lymphoma.

To evaluate the effectiveness and safety of autologous cytokine-induced killer (CIK) cells in elderly patients with diffuse large B-cell lymphoma. Peripheral blood mononuclear cells (PBMC) were isolated from nine elderly patients with diffuse large B-cell lymphoma. PBMCs were augmented by priming with interferon gamma (IFN-γ) followed by IL-2 and monoclonal antibody (mAb) against CD3.

[Clinical study of autologous cytokine induced killer cell infusion treating for elderly patients with myelodysplastic syndrome].

Objective of this study was to evaluate the effectiveness and safety of autologous cytokine induced killer (CIK) cells combined with IL-2 in treatment of elderly patients with myelodysplastic syndromes (MDS). Peripheral blood mononuclear cells were isolated from 6 elderly MDS patients and were stimulated by cytokines in vitro to form CIK cells. The autologous CIK cells were then infused back into the corresponding patients.

[Application of immune function test to evaluate effect of cytokine-induced autologous killer cell infusion for elderly patients with hematological malignancies].

The aim of study was to explore the efficacy of cytokine induced autologous killer (CIK) cell infusion as an immune therapy for elderly patients with hematological malignancies. Peripheral blood mononuclear cells (PBMNC) were isolated from 20 elderly patients with hematological malignancies, and then augmented by priming with human recombinant interferon gamma (rhIFN-γ) followed by human recombinant interleukin 2 (rhIL-2) and monoclonal antibody (mAb) against CD3. The obtained autologous CIK cells [(2-3)×10(9)] were infused back to individual patients, then followed by subcutaneous injection of IL-2 at single daily dose of 1×10(6) U for 10 consecutive days.

[Clinical study of autologous cytokine induced killer cells combined with IL-2 for therapy of elderly patients with B-cell malignant lymphoma].

Objective of this study was to evaluate the effectiveness and safety of autologous cytokine induced killer (CIK) cells combined with IL-2 in treatment of elderly patients with B-cell malignant lymphoma. Peripheral blood mononuclear cells (PBMNC) were isolated from 9 elderly patients with B-cell malignant lymphoma, and then induced into CIK cells by IFN-γ, IL-2 and monoclonal antibody (mAb) against CD3. The autologous CIK cells [(2-3)×10(9)] thus obtained were infused back to individual patients, then followed by subcutaneous injection of IL-2 at single daily dose of 1×10(4) U/day for 10 consecutive days.
