T Cells Expressing a Fully-Human Anti-CD30 Chimeric Antigen Receptor for Treating CD30-Expressing Lymphomas

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: * Improved treatments for a variety of treatment-resistant, TNFRSF8 (CD30)-expressing malignancies including Hodgkin lymphoma, anaplastic large cell lymphoma, and other CD30- expressing lymphomas are needed. * T cells can be genetically modified to express chimeric antigen receptors (CARs) that specifically target malignancy-associated antigens. * Autologous T cells genetically modified to express CARs targeting the B-cell antigen B-lymphocyte antigen CD19 (CD19) have caused complete remissions in a small number of patients with lymphoma. These results demonstrate that CAR-expressing T cells can have anti-lymphoma activity in humans. * CD30 expression can be easily detected by immunohistochemistry on lymphoma cells, which allows selection of CD30-expressing malignancies for treatment. * CD30 is not known to be expressed by normal cells except for a small number of activated lymphocytes. * We have constructed a novel fully-human anti-CD30 CAR that can specifically recognize CD30-expressing target cells in vitro and eradicate CD30-expressing tumors in mice. * This particular CAR has not been tested before in humans. * Possible toxicities include cytokine-associated toxicities such as fever, hypotension, and neurological toxicities. Elimination of a small number of normal activated lymphocytes is possible, and unknown toxicities are also possible. Objectives: Primary -Determine the safety and feasibility of administering T-cells expressing a novel fully human anti-CD30 CAR to patients with advanced CD30-expressing lymphomas. Eligibility: * Patients must have anaplastic large cell lymphoma, peripheral T-cell lymphoma not otherwise specified, diffuse large B-cell lymphoma not otherwise specified, primary mediastinal B-cell lymphoma, grey zone lymphoma, enteropathy associated T-cell lymphoma, or extranodal natural killer (NK)/T-cell lymphoma, nasal type * Patients must have malignancy that is both measurable on a computed tomography (CT) scan with a largest diameter of at least 1.5 cm and possessing increased metabolic activity detectable by positron emission tomography (PET) scan. Alternatively, patients with lymphoma detected by flow cytometry of bone marrow are eligible. * Patients must have a creatinine of 1.6 mg/dL or less and a normal cardiac ejection fraction. * An Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 is required. * No active infections are allowed including evidence of active human immunodeficiency virus (HIV), hepatitis B, or hepatitis C. At the time of protocol enrollment patients must be seronegative for cytomegalovirus (CMV) by antibody testing or must have a negative blood CMV polymerase chain reaction (PCR). * Absolute neutrophil count greater than or equal to 1000/micro L, platelet count greater than or equal to 55,000/micro L, hemoglobin greater than or equal to 8g/dL * Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) less or equal to 3 times the upper limit of the institutional normal unless liver involvement by malignancy is demonstrated. * At least 14 days must elapse between the time of any prior systemic treatment (including corticosteroids above 5 mg/day of prednisone or equivalent corticosteroid dose) and initiation of required leukapheresis. * Clear CD30 expression must be detected on 75% or more of malignant cells from either bone marrow or lymphoma mass by flow cytometry or immunohistochemistry. The patient s malignancy will need to be assessed for CD30 expression by flow cytometry or immunohistochemistry performed at the National Institutes of Health (NIH). If unstained, paraffin-embedded bone marrow or lymphoma sections are available from prior biopsies, these can be used to determine CD30 expression by immunohistochemistry; otherwise, patients will need to come to the NIH for a biopsy to determine CD30 expression. The sample for CD30 expression can come from a biopsy obtained at any time before enrollment, unless the patient has received a prior anti-CD30 monoclonal antibody, in which case the sample must come from a biopsy following completion of the most recent anti-CD30 monoclonal antibody treatment. * Eligible patients with diffuse large B-cell lymphoma or primary mediastinal B-cell lymphoma must have received 2 prior treatment regimens at least 1 of which included an anthracycline and an anti-CD20 monoclonal antibody. * Patients who have never had an allogeneic hematopoietic stem cell transplant as well as patients who have had a 9/10 or 10/10 human leukocyte antigen (HLA)-matched sibling or a 9/10 or 10/10 HLA- matched unrelated donor hematopoietic stem cell transplant are potentially eligible. * Women who are pregnant or plan to become pregnant will be excluded.
