Extracted eligibility criteria

Cancer type

Non-Hodgkin Lymphoma

Biomarker criteria

Required: CD5 positivity (≥ 50% expression by approved diagnostic test or LDT) (≥ 50%)

CD5 positivity confirmed by local laboratory using an approved diagnostic test or LDT. CD5 positivity is currently defined as having ≥ 50% CD5 expression.

Prior therapy

Must have received: standard of care therapy — CTCL: ≥ 2 prior lines; PTCL: ≥ 1 prior line

r/r CTCL that has failed ≥ 2 prior lines of standard of care (SoC) therapy. r/r PTCL that has failed ≥ 1 prior lines of SoC therapy.

Must have received: antibody-drug conjugate (brentuximab vedotin) — CD30+ disease

patients with CD30+ disease should have received brentuximab vedotin

Cannot have received: CD5-targeted therapy

Prior treatment with any CD5-targeted therapy

Cannot have received: bendamustine (bendamustine)

Exception: unless received an allo-HSCT in the interim

Received bendamustine prior to enrollment (unless received an allo-HSCT in the interim)

Lab requirements

Blood counts

ANC ≥ 1500/μL (≥ 1000/μL for patients with prior HSCT or marrow involvement); absolute lymphocyte count ≥200 cells/μL; hemoglobin ≥ 8 g/dL (transfusion permitted); platelet count ≥ 75,000/μL (≥50,000/μL for patients with marrow involvement)

Kidney function

calculated creatinine clearance > 30 mL/min

Liver function

Total bilirubin < 1.5 x ULN (< 2 × ULN if liver involvement); if no liver involvement and total bilirubin ≥1.5 x ≤ ULN, direct bilirubin < ULN (Gilbert syndrome); AST/ALT < 3 × ULN (5 x ULN if liver involvement); albumin > 2.5 g/dL.

Cardiac function

LVEF ≥ 50% by Echo or radionuclide scan

Adequate bone marrow function defined as: ANC ≥ 1500/μL (≥ 1000/μL for patients with prior HSCT or marrow involvement); absolute lymphocyte count ≥200 cells/μL; hemoglobin ≥ 8 g/dL (transfusion permitted); platelet count ≥ 75,000/μL (≥50,000/μL for patients with marrow involvement). Cardiac: LVEF ≥ 50% by Echo or radionuclide scan. Pulmonary: oxygen saturation ≥ 92% (room air). Renal: calculated creatinine clearance > 30 mL/min. Liver: Total bilirubin < 1.5 x ULN (< 2 × ULN if liver involvement); if no liver involvement and total bilirubin ≥1.5 x ≤ ULN, direct bilirubin < ULN (Gilbert syndrome); AST/ALT < 3 × ULN (5 x ULN if liver involvement); albumin > 2.5 g/dL.
