Pilot Study of Ruxolitinib in Relapsed or Refractory Hodgkin Lymphoma and Primary Mediastinal Large B-cell Lymphoma

Pilot Study of Ruxolitinib in Relapsed or Refractory Hodgkin Lymphoma and Primary Mediastinal Large B-cell Lymphoma

The purpose of this study is that ruxolitinib may be a possible treatment option for relapsed or refractory patients with Hodgkin and primary mediastinal large B-cell lymphoma.

Patients will take ruxolitinib 20 mg orally twice a day, 40mg in total per day, for 4 weeks.4 weeks is 1 cycle. Treatment will be continued until documented disease progression or unacceptable toxicity and the maximum period of treatment is 16 cycles.

Inclusion Criteria:

• Histologically proven Hodgkin lymphoma or primary mediastinal large B-cell lymphoma
• Patient should belong to any one of following clinical situations A.Patient who are not able to get autologous stem cell transplantation after relapsing the salvage chemotherapy B. Relapsed after autologous stem cell transplantation C. Refractory to salvage chemotherapy or autologous stem cell transplantation

A. Serum aspartate transaminase (AST; serum glutamic oxaloacetic transaminase (SGOT)) and serum alanine transaminase (ALT; serum glutamic pyruvic transaminase (SGPT)) ≤2.5 x local laboratory upper limit of normal (ULN), or AST and ALT less than or equal to 5 x ULN if liver function abnormalities are due to underlying malignancy B. Total serum bilirubin ≤1.5 x ULN C. Absolute neutrophil count (ANC) ≥ 1500/µL D. Platelets ≥ 100,000/µL E. Hemoglobin ≥ 9.0 g/dL (may be transfused or erythropoietin treated) F.
