Despite the progress in the therapy, Hodgkin's Lymphoma (HL) remains fatal for more than 15% of patients. Even in patients who are cured, the morbidity of therapy is substantial and long-lasting. New therapeutic agents are required therefore not only to further reduce mortality but also to alleviate morbidity. The majority of HL express the CD30 antigens. CD30 expression is routinely used for the diagnosis of HL. Preclinical observations support CD30 as a viable target of CAR-T therapy. This phase Ib/II study was conducted based on these observations. The purpose of this study is to determine the tolerability of ATLCAR.CD30.CCR4 cells in subjects with Hodgkin's Lymphoma and identify a recommended dose for further. This is a single-center, open-label phase Ib/II trial that uses a 3+3 design to identify a recommended phase 2 dose (RP2D) of ATLCAR.CD30.CCR4 cells in Hodgkin's Lymphoma. The phase II portion is designed to determine the PFS of ATLCAR.CD30.CCR4 in Hodgkin's Lymphoma. Subjects will be enrolled on 1 of 3 dose levels as determined by a 3+3 design. Up to 25 evaluable subjects may then be enrolled in the phase II portion of the study. Subjects may have cells procured to manufacture the ATLCAR.CD30.CCR4 cells if they meet eligibility for procurement. During the time period necessary to manufacture the ATLCAR.CD30.CCR4 cells, Subjects will be allowed to receive standard-of-care bridging therapy at the discretion of their local oncologist. Prior to cell infusion, subjects will undergo additional eligibility evaluations, and then if eligible, will undergo lymphodepletion followed by cell infusion 2-14 days later. Subjects will then be followed for 15 years as is required for studies involving gene transfer experiments.

RECRUITINGPhase 1b adverse events
Toxicity will be graded as the number of participants with adverse events (AE) related to the administration of ATLCAR.CD30.CCR4 cells in subjects with CD30+ Hodgkin's Lymphoma. AEs will be classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Dose Limiting Toxicities (DLTs) are defined as at least possibly related to CAR.B7-H3T cell product administration.
Time frame: Up to 6 weeks
Phase 1b Toxicity Cytokine Release Syndrome (CRS)
CRS will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) CRS Consensus Grading related to the administration of ATLCAR.CD30.CCR4 cells in subjects with CD30+ Hodgkin's Lymphoma. Grade 1 - Mild: Fever ≥38\^ o C, No hypotension, No hypoxia, Grade 2 - Moderate: Fever ≥38\^ o C, Hypotension not requiring vasopressors, Hypoxia requiring low-flow nasal cannula (≤6 L/minute) or blow-by, Grade 3 - Severe: Fever ≥ 38\^ o C, Hypotension requiring a vasopressor with or without vasopressin, Hypoxia requiring high-flow nasal cannula (\>6 L/minute), facemask, nonrebreather mask, or Venturi mask, Grade 4 - Life-threatening: Fever ≥38\^oC, Hypotension requiring multiple vasopressors (excluding vasopressin), Hypoxia requiring positive pressure (e.g. Continuous positive airway pressure, BiPAP, intubation, mechanical ventilation), Grade 5 - Death
Time frame: Up to 6 weeks
Phase 1b Toxicity Immune effector cell-associated neurotoxicity syndrome (ICANS)
Neurotoxicity will be graded according to the Immune effector cell-associated neurotoxicity syndrome (ICANS) criteria related to the administration of ATLCAR.CD30.CCR4 cells in subjects with CD30+ Hodgkin's Lymphoma. Immune effector cell-associated neurotoxicity syndrome (ICANS) symptoms will be graded according to the criteria outlined in the protocol on a scale from 1 (mild) to 4 (critical). Cytokine release syndrome (CRS) will be graded according to criteria outlined in the protocol on a scale from 1 (mild) to grade 5 (death).
Time frame: Up to 6 weeks
Phase II Median Progression Free Survival (PFS)
Median PFS will be measured from the first day of lymphodepletion chemotherapy prior to ATLCAR.CD30.CCR4 cell infusion to progression (as defined by Lugano Criteria or death. Complete: Complete metabolic response on Positron emission tomography (PET) or the largest transverse diameter (LDi) of target nodes/masses ≤ 1.5 cm and no extra lymphatic disease on Computerized Tomography (CT). Partial: reduced uptake compared with baseline and residual mass(es) on PET and ≥50% decrease in the sum of the products of diameters (SPD) of nodes and extranodal sites on CT. No Response or Stable Disease: No metabolic response on PET or \< 50% decrease from baseline in SPD, measurable nodes and extranodal sites; no criteria for the progressive disease are met on CT. Progressive Disease: Score 4 or 5 with an increase in the intensity of uptake from baseline and/or new focus on PET, LDi\>1.5 cm or by ≥ 50% from nadir.
Time frame: Up to 6 months
Phase Ib Dose Limiting Toxicity
The recommended phase 2 dose (RP2D) of ATLCAR.CD30.CCR4 cells will be determined based on the 3+3 dose finding rule as specified in the protocol for the tolerability of ATLCAR.CD30.CCR4 cells will be assessed using NCI-CTCAE v5 and ASTCT Consensus CRS Grading Criteria. * Grade 3-5 allergic reactions related to the CAR-T cell infusion. * A treatment-emergent Grade 3 CRS that does not improve to Grade 0-1 by 72 hours or Grade 4 CRS * Grade ≥3 ICANS that are unresponsive to the standard of care interventions and do not decrease to Grade ≤1 within 7 days or grade 4 ICANS of any duration that has evidence of cerebral edema and/or generalized convulsive status epilepticus. * Any treatment-emergent Grade 4 non-hematologic AE that does not resolve to Grade 2 within 7 days. * Any Grade 5 events are not due to the underlying malignancy.
Time frame: Up to 6 weeks
Overall Survival (OS)
OS is defined as the time from the first day of lymphodepletion to date of death for any cause. Subjects who have not had an event will be censored at the date of last assessment documenting the subject was alive.
Time frame: Up to 6 months
Duration of Response (DOR)
DOR is defined as the time from partial response (PR) or better to progressive disease (PD) per Lugano Criteria. Complete Response: Complete metabolic response on Positron emission tomography (PET) or Target nodes/nodal masses must be ≤ 1.5 cm in the largest transverse diameter (LDi) or no extra lymphatic of disease on Computerized Tomography (CT).
