Study of Rituximab and Brentuximab Vedotin for Relapsed Classical Hodgkin Lymphoma

This research is being done to study a combination of drugs for relapsed Hodgkin's Lymphoma
(HL) that may be easier to tolerate than standard therapies and that does not involve an
autologous blood or marrow transplant (BMT, also called a stem cell transplant).The study is
for people with HL who have never received treatment for relapsed lymphoma, except for
radiation therapy. Usually, when HL relapses for the first time, the standard is to receive
combinations of chemotherapy, including an autologous blood or marrow transplant (BMT, also
called a stem cell transplant) which has about a 40% cure rate. BMT may cure the HL, but also
may be associated with serious side effects and risks. This research looks at a combination
of drugs for relapsed HL that may not have the side effects of standard therapies and that
does not involve BMT. The goal is to treat the lymphoma effectively with drugs that we expect
will have fewer side effects, while avoiding a treatment like BMT.

Inclusion Criteria:

- Age > 16 years

- Biopsy-proven diagnosis of classical Hodgkin Lymphoma (regardless of HRS cell CD20
expression) per the World Health Organization classification criteria24; lymphocyte
predominant histology is excluded

- Untreated relapse of classical Hodgkin Lymphoma (with the exception of steroids) as
follows:HL that relapsed > 3 months after completion of first-line chemotherapy or
combined modality therapy, and has not yet been treated with salvage chemotherapy,
Stage I-II HL that relapsed > 3 months after first-line chemotherapy, then relapsed
after radiation therapy delivered with curative intent, and has not yet been treated
with salvage chemotherapy

- Radiographically measurable disease (> 1 focus of lymphoma measuring > 1.5 cm)

- Baseline laboratories: ANC > 1000/uL and platelets > 75,000/uL, unless due to bone
marrow involvement by lymphoma, Serum creatinine < 2.0 mg/dL, Total bilirubin < 2.0
mg/dL (excluding Gilbert's syndrome), unless due to lymphoma

- ECOG performance status 0, 1 or 2.

Exclusion Criteria:

- Active concurrent malignancy with the exception of superficial non-melanoma skin
cancer and cervical carcinoma in situ.

- Primary induction failure, defined as failure to achieve CR with first-line
chemotherapy or chemoradiation, disease progression during first-line chemotherapy or
chemoradiation, or progression or biopsy-proven disease persistence within 8 weeks of
first-line therapy completion

- Prior brentuximab vedotin or rituximab for lymphoma

- Grade > 2 peripheral neuropathy

- HIV infection, active hepatitis B infection, or active hepatitis C infection
