Lenalidomide and Ipilimumab After Stem Cell Transplant in Treating Patients With Hematologic or Lymphoid Malignancies

A Pilot Study of Lenalidomide Alternating With Ipilimumab Post Allogeneic and Autologous Stem Cell Transplantation

This pilot clinical trial studies the side effects of lenalidomide and ipilimumab after stem cell transplant in treating patients with hematologic or lymphoid malignancies. Biological therapies, such as lenalidomide, may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Immunotherapy with monoclonal antibodies, such as ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide with ipilimumab may be a better treatment for hematologic or lymphoid malignancies.

PRIMARY OBJECTIVES:

I. To assess the safety of lenalidomide in combination with ipilimumab in autologous and allogeneic stem cell transplantation.

SECONDARY OBJECTIVES:

I. Overall response rate. II. Overall survival, progression-free survival. III. Cumulative incidence of acute and chronic graft-versus-host disease (GVHD) with the competing risk of relapse in allogeneic transplant patients.

OUTLINE:

Patients receive lenalidomide orally (PO) once daily (QD) on days 1-21 of courses 1, 3, 5 and 7. Beginning 1-3 days after the last dose of lenalidomide patients receive one dose of ipilimumab intravenously (IV) over 90 minutes of courses 2, 4, 6 and 8. Treatment repeats every 28 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 1, 3, 6, 12, 24, and 36 months.

Inclusion Criteria:

• Hematologic or lymphoid malignancy

• Allogeneic patients if: i. patients had engrafted donor cells (i.e., > 20% donor T-cell from peripheral blood [PB]/polymerase chain reaction [PCR]); and, ii. patients NOT in complete remission (CR) after their allogeneic transplant, and off tacrolimus and/or mycophenolate mofetil for at least 3 to 4 weeks with no signs of GVHD; or, iii. patients had evidence of relapse after their transplant who are off tacrolimus and/or mycophenolate mofetil or other immunosuppressants for GVHD for 3 to 4 weeks with no signs of GVHD (prednisone doses =< 10 mg are permitted as stated previously)

• Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and diffusing capacity of the lung for carbon monoxide (DLCO) >= 40% within 3 months of study entry (or within 1 month if received chemotherapy within the past 3 months)
• Serum creatinine =< 1.6 mg/dL and creatinine clearance >= 30 ml/min; creatinine clearance will be calculated using the Cockcroft-Gault equation
• Serum glutamate pyruvate transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT) less than 2 x the upper limit of normal range (unless related to Gilbert's disease or medications)
• Direct bilirubin < 1.6 (unless related to Gilbert's disease or medications)
• Patient or legally authorized representative able to sign informed consent
• Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10-14 days prior to study entry

Exclusion Criteria:

• Immunotherapy or chemotherapy with approved or investigational anticancer therapeutics within 4 weeks of first dose
• Patients on alemtuzumab within 6 weeks prior to consenting
