Endpoints

Efficacy Assessments
Subjects will be assigned a response status based on imaging and lymphoma assessments. Disease response will
be assessed by a BICR and the investigator according to the Lugano Classification Revised Staging System for
nodal non-Hodgkin and Hodgkin lymphomas. Radiographic disease evaluations, including contrast-enhanced
CT scans of neck, chest, abdomen and pelvis, will be assessed at baseline, then every 6 weeks from
randomization until Week 48 (±7 days), then every 12 weeks (±7 days) thereafter. A PET scan is required at
baseline and every 6 weeks until Week 48 (±7 days), then every 12 weeks (±7 days) thereafter. Once the PET is
negative per the investigator, no further PET scans are required. A diagnostic quality CT-PET scan should also
be performed at the time of suspected clinical progression.
Pharmacokinetic and Immunogenicity Assessments
Blood samples will be obtained for PK and immunogenicity evaluation at protocol-defined time points. PK
parameters to be estimated include concentration at the end of infusion for brentuximab vedotin (Ceoi) and
trough concentration (Ctrough). Immunogenicity will be evaluated with measurements of ADA in serum.
Biomarker Assessments
Tumor samples will be collected for biomarker assessment including, but not limited to CD30 expression by
IHC, prognostic molecular phenotypes, and gene expression profiling. Blood will be collected for
chemokines/cytokines of interest.
Safety Assessments
Safety assessments will include the surveillance and recording of adverse events (AEs), physical examination
findings, and laboratory tests.
Other Assessments
Patient-Reported Outcomes and Health Economics: Health outcomes assessments will include health-related
quality of life and healthcare utilization, which will be described in the statistical analysis plan (SAP).

Inclution Criteria

1. Subjects with relapsed or refractory diffuse and transformed large B-cell lymphoma (R/R
DLBCL). DLBCL and cell of origin (GCB versus non-GCB) will be histologically
determined by the most recent local pathology assessment for the purposes of study
eligibility and stratification. The following subtypes of DLBCL are eligible for
enrollment:
a. Not otherwise specified (NOS)
b. Intravascular large B-cell

lymphoma
c. DLBCL associated with chronic
inflammation
d. EBV-positive NOS
e. ALK-positive
f. T-cell-/histiocyte-rich large B-cell
lymphoma
g. Primary mediastinal large B-cell
lymphoma
h. High-grade B-cell lymphoma with
translocations of MYC and BCL2
and/or BCL6 (double-/triple-hit
lymphoma)
i. High-grade NOS B-cell
lymphomas
j. Primary cutaneous DLBCL (leg
type)
k. DLBCL arising from transformed
indolent lymphomas/leukemias
2. Subjects must have R/R disease following ≥2 lines of prior systemic therapy.
3. Subjects must be HSCT or CAR-T ineligible according to the investigator and must meet
at least one of the following criteria:
a. One or more co-morbidities, including cardiac, pulmonary, renal or hepatic
dysfunction that in the opinion of the Investigator make the subject medically unfit to
receive HSCT or CAR-T therapy.
b. Active disease following induction and salvage chemotherapy
c. Inadequate stem cell mobilization (for HSCT)
d. Relapse following prior HSCT or CAR-T
e. Unable to receive CAR-T therapy due to financial, geographic, or insurance issues.
4. Subjects will need to have formalin-fixed paraffin-embedded tumor tissue (obtained
≤4 weeks before Day 1) submitted to the central pathology lab for the determination of
CD30 expression, which will be centrally determined by visual assessment for any
detectable level of CD30 on tumor cells by IHC (using the anti-CD30 BerH2 antibody).
A subject with an archive sample that has had local CD30 testing, and whose recent
biopsy does not contain viable tumor, may be stratified based on the local result. If a
recent biopsy is not available (obtained ≤4 weeks before Day 1) and a biopsy is not
medically feasible or appropriate, contact the medical monitor. If, in the determination of
the investigator, it is not feasible for the subject to undergo central pathology evaluation
prior to randomization, and after discussion with the Medical Monitor, the subject may be
stratified based on CD30 expression from the local pathology lab. Subjects who are
stratified based on local pathology lab results must have archived tumor tissue sent in for
central CD30 evaluation within 2 weeks of enrollment.
5. Age 18 and older.
6. An Eastern Cooperative Oncology Group (ECOG) performance status score of 0 to 2.
7. Subjects must have fluorodeoxyglucose (FDG)-avid disease by positron emission
tomography (PET) and bidimensional measurable disease of at least 1.5 cm by computed
tomography (CT), as assessed by the site radiologist within 28 days of Day 1.
8. The following baseline laboratory data within 28 days of Day 1:
a. Absolute neutrophil count (ANC) ≥1000/μL.
b. Platelet count ≥50,000/μL at least 7 days after last chemotherapy with no platelet
transfusion in the 7 days prior to testing.
c. Hemoglobin ≥8.0 g/dL and have not received a transfusion in the 7 days prior to
testing
d. Serum bilirubin ≤1.5 x upper limit of normal (ULN) or ≤3 x ULN for subjects with
Gilbert’s disease or documented hepatic involvement with lymphoma.
e. Estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 using the
Modification of Diet in Renal Disease (MDRD) study equation.
o eGFR (mL/min/1.73 m2) = 175 x (serum creatinine [Scr])-1.154 x (Age)-0.203 x
(0.742 if female) x (1.212 if African American)
f. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 x ULN
or 5.0 x ULN for subjects with documented hepatic involvement with lymphoma.

conditions.
a. Must avoid pregnancy for at least 4 weeks before beginning lenalidomide therapy,
during therapy, during dose interruptions, and for at least 12 months after completing
therapy. Subjects must commit either to abstain continuously from heterosexual
sexual intercourse or to use 2 methods of reliable birth control (see Appendix C),
beginning 4 weeks prior to initiating treatment with lenalidomide, during therapy,
during dose interruptions, and continuing for 12 months following discontinuation of
lenalidomide therapy. Two negative serum β-HCG pregnancy tests must be obtained

continuing through 12 months after the final dose of study drug.
11. The following requirements for subjects who are human immunodeficiency virus
(HIV)-positive:
● CD4+ T-cell counts ≥350 cells/mm3 within 28 days of Day 1
● No acquired immune deficiency syndrome-defining opportunistic infection within the
past 12 months
● On established highly active antiretroviral therapy for at least 4 weeks with an HIV
viral load less than 400 copies/mL within 28 days of Day 1 (see Section 5.6.2 for
subjects receiving strong CYP3A inhibitors).
12. Subjects must be registered into the mandatory lenalidomide REMS®/risk minimization
programs and be willing to comply with its requirements. Per standard lenalidomide
REMS/risk minimization programs requirements, all physicians who prescribe
