• Transformed Mycosis Fungoides (tMF) without blood involvement;

• Primary Cutaneous Aggressive Epidermotropic CD8+ Cytotoxic T-Cell Lymphoma;

• Subcutaneous Panniculitis-like T-cell Lymphoma.

ii. Must have received at least one prior line of systemic therapy for their lymphoma. Additional prior treatment provisions required for the following indications:

• Participants with Anaplastic Large Cell Lymphoma (ALCL) must have received prior Brentuximab vedotin, unless contraindicated.

• Participants with Subcutaneous Panniculitis-like T-cell Lymphoma or Transformed Mycosis Fungoides (tMF) must have received at least 2 prior lines of systemic therapy.

c. Hodgkin Lymphoma (HL)

i. Patients with histologically proven classical Hodgkin Lymphoma that is CD45 positive by IHC or flow cytometry by a CLIA certified laboratory; AND

ii. Relapsed/refractory disease after at least 2 prior lines of therapy which must include the following:

• Brentuximab vedotin and immune checkpoint inhibitors (unless contraindicated); AND
• Autologous stem cell transplant (unless patient has chemorefractory disease to salvage treatment) d. Large Cell Transformation of CLL (Richter's Transformation) i. Patients must be primary refractory or received at least 1 prior line of treatment for Richter's Transformation.

• Patients are appropriate candidates for autologous HSCT as per physician-investigator clinical discretion

• Patients with relapsed disease after prior allogeneic SCT must meet the following criteria:

a. Have no active GVHD and require no immunosuppression

b. Are more than 6 months from transplant at the time of physician-investigator confirmation of eligibility

• Adequate organ function defined as:

• Serum creatinine ≤ 1.5x ULN or estimated creatinine clearance ≥ 35 mL/min and not on dialysis
• ALT/AST ≤ 3 x ULN

Exclusion criteria

• Active hepatitis B or hepatitis C infection
• Any active, uncontrolled infection.
• Class III/IV cardiovascular disability according to the New York Heart Association Classification.
• Clinically apparent arrhythmia or arrhythmias that are not stable on medical management within two weeks of physician-investigator confirmation of eligibility.
• Severe, active co-morbidity that, in the opinion of the physician-investigator, would preclude participation in this study.
• Prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen.
• Active acute or chronic GVHD requiring systemic therapy.
• Dependence on systemic steroids or immunosuppressant medications. For additional details regarding use of steroid and immunosuppressant medications.
• Active CNS involvement. Patients with a history of CNS involvement that was successfully treated are eligible. A CNS evaluation is only required for eligibility if a subject is experiencing signs/symptoms of CNS involvement.
• Patients with evidence of a circulating T-cell malignancy as measured by flow cytometry.
