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

• Status: Active, not recruiting
• Trial end date: 2024-06-30
• Target enrollment: 0
• Participant gender: All

Summary

Background:

• Improved treatments for a variety of treatment-resistant, 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 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 fullyhuman anti-CD30 CAR to patients with advanced CD30-expresssing 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, enteropathyassociated T-cell lymphoma, or extranodal NK/T-cell lymphoma, nasal type

• Patients must have malignancy that is both measurable on a CT scan with a largest diameter of at least 1.5 cm and possessing increased metabolic activity detectable by 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 ECOG performance status of 0-2 is required.

• No active infections are allowed including evidence of active HIV, hepatitis B, or hepatitis C. At the time of protocol enrollment patients must be seronegative for CMV by antibody testing or must have a negative blood CMV 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 ALT and 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 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 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.

Design:

• This is a phase I dose-escalation trial.

• Patients will undergo leukapheresis.

• T cells obtained by leukapheresis will be genetically modified to express an anti-CD30 CAR.

• Patients will receive a lymphocyte-depleting chemotherapy conditioning regimen with the intent of enhancing the activity of the infused anti-CD30 CAR-expressing T cells.

• Patients must have measurable malignancy as defined by at least one of the criteria below.

• Lymphoma mass that is measurable (minimum 1.5 cm in largest diameter) by CT scan is required unless bone marrow lymphoma is detectable.

• For a lymphoma mass to count as measurable malignancy, it must have abnormally increased metabolic activity when assessed by positron emission tomography (PET) scan.

• For lymphoma with only bone marrow involvement, no mass is necessary, but if a mass is not present, bone marrow malignancy must be detectable by flow cytometry.

Other Inclusion Criteria:

• Greater than or equal to 18 years of age and less than or equal to age 73.

• Able to understand and sign the Informed Consent Document.

• Clinical performance status of ECOG 0-2

Pre-menopausal patients (female patients who have had a menstrual period within the last year) must be willing to practice birth control from the time of enrollment and for one year following the final CAR T cell infusion.

• Seronegative for HIV antibody. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who are HIV seropositive can have decreased immune -competence and thus are less responsive to the experimental treatment and more susceptible to its toxicities.)

• Seronegative for HTLV-1.

• Negative for hepatitis B surface antigen. Positive hepatitis B tests can be further evaluated by confirmatory tests; and if confirmatory tests are negative, the patient can be enrolled.

• Seronegative for hepatitis C antibody unless antigen negative. If hepatitis C antibody test is positive, then patients must be tested for the presence of RNA by RT-PCR and be HCV RNA negative to be enrolled.

• A patient with a prior history of hepatits B or a prior history of hepatitis C may participate, as long as the patient s viral hepatitis has been treated, and the patient has no detectable HBV DNA or HCV RNA.

• At time of protocol enrollment, the patient should be negative for CMV by antibody testing or by PCR. In case of disagreement between these 2 CMV tests, the tests will be repeated and Dept. of Laboratory Medicine consulted.

Because this protocol requires collection of autologous blood cells by leukapheresis in order to prepare CAR T cells, systemic anti-malignancy therapy including systemic corticosteroid therapy at doses greater than prednisone 5 mg/day or the equivalent corticosteroid doses is not allowed within 14 days prior to the required leukapheresis. NOTE: Because of the long half-life and potential to affect CAR T-cells, 30 days must elapse from the time of administration of anti-PD-1 or anti-PD-L1 antibodies or other agents that in the opinion of the PI can stimulate immune activity and infusion of CAR T-cells.

• Normal cardiac ejection fraction (greater than or equal to 50% by echocardiography) and no evidence of hemodynamically significant pericardial effusion as determined by an echocardiogram within 4 weeks of the start of the treatment protocol.

• Donor T cell engraftment after allo-HSCT (>90% donor chimerism of the T-cell compartment).

• Patients must be at least 90 days post-transplant.

• Patients must be off all systemic immunosuppressive drugs including corticosteroids at doses of greater than 5 mg/day prednisone or equivalent, if given for treatment of graft versus host disease, for at least 28 days prior to protocol enrollment and must remain off immunosuppressive drugs while enrolled on the protocol. Patients must not be taking any systemic steroids at doses greater than 5 mg/day prednisone or equivalent at all for 14 days prior to apheresis and initiation of chemotherapy.
