• 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:

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

2\. 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:

1. Brentuximab vedotin and immune checkpoint inhibitors (unless contraindicated); AND
2. 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.

4\. Patients are appropriate candidates for autologous HSCT as per physician-investigator clinical discretion

5\. 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

6\. Adequate organ function defined as:

1. Serum creatinine ≤ 1.5x ULN or estimated creatinine clearance ≥ 35 mL/min and not on dialysis
2. ALT/AST ≤ 3 x ULN
3. Direct bilirubin ≤ 2.0 mg/dl; for patients with Gilbert's syndrome direct bilirubin must be ≤ 3.0 mg/dl

5. DLCO > 45% predicted value; adjusted for level of hemoglobin
6. Must have minimum level of pulmonary reserve defined as ≤ Grade 1 dyspnea and pulse oxygen > 92% on room air 7. ECOG Performance Status 0-1

Exclusion Criteria:

1. Active hepatitis B or hepatitis C infection
2. Any active, uncontrolled infection.
3. Class III/IV cardiovascular disability according to the New York Heart Association Classification.
4. Clinically apparent arrhythmia or arrhythmias that are not stable on medical management within two weeks of physician-investigator confirmation of eligibility.
5. Severe, active co-morbidity that, in the opinion of the physician-investigator, would preclude participation in this study.
6. Prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment of the investigational regimen.
7. Active acute or chronic GVHD requiring systemic therapy.
8. Dependence on systemic steroids or immunosuppressant medications. For additional details regarding use of steroid and immunosuppressant medications.
9. 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.
