Chronic Lymphocytic Leukemia Clinical Trial
Ofatumumab, High Dose Methylprednisolone, Ofatumumab and Lenalidomide Consolidative Therapy for Untreated CLL/SLL
The main purpose of this study is to see if ofatumumab with methylprednisolone followed by additional treatment with ofatumumab and lenalidomide can help people with Chronic Lymphocytic Leukemia (leukemia-cll/" >CLL) get rid of their CLL for a long period of time. Researchers also want to find out if the combination of ofatumumab with methylprednisolone followed by additional treatment with ofatumumab and lenalidomide is safe and tolerable.
This is a phase II, single institution, and non-randomized study of patients with untreated CLL/SLL, utilizing a two-stage trial design. The primary endpoint for this trial is the combined complete and partial response rate (at 3 months-the end of cycle 3) to the protocol therapy. We anticipate this trial will have a complete response (CR) and partial response (PR) rate of at least 80%.
A two-stage design is employed for this trial. The null/unacceptable CR+PR response rate is ≤ 60% while the anticipated true response rate to the protocol treatment is at least 80% for each disease cohort. At the first stage, 26 patients will be accrued to the trial. If 15 or fewer of these patients respond, then the trial will be terminated early and the response rate to the protocol treatment will be deemed unacceptable (≤ 60%). Otherwise, if more than 15 patients respond during the first stage, an additional 19 patients will be enrolled to this trial during stage 2 for a total of 45 patients. If 32 or fewer of these 45 patients respond to the protocol treatment at the end of stage 2, no further investigation of the protocol treatment is considered warranted. On the other hand, if more than 32 patients out of the 45 enrolled patients respond, the protocol treatment will be considered promising. If the true response rate is ≤ 60%, the probability of ending the trial at stage 1 is 0.48. If, however, the true response rate is at least 80%, then the probability of ending the trial at stage 1 is only 0.01. This two-stage design has an overall alpha level of 0.045 and a power of 0.90.
Understand and voluntarily sign an informed consent form
Able to adhere to the study visit schedule and other protocol requirements
Patients must have histologically or cytologically confirmed CD5+/CD20+ B-Cell chronic lymphocytic leukemia or small lymphocytic lymphoma. The diagnosis of CLL is based upon the National Comprehensive Cancer Network (NCCN) guidelines. Any outside pathology slides used as inclusion criteria for the patient will be reviewed at this institution to confirm the diagnosis. The patient must meet all of the following CLL criteria to participate in this study: absolute lymphocyte count > 5000/μL; CD20+ and CD5+; Bone marrow lymphocytes ≥ 30%; Or previous confirmed diagnosis of CLL/SLL with less than 5000/μl or less than 30% lymphocytes in bone marrow.
Patients are eligible if they have stage III or IV disease. Patients with stage 0, I or II disease will be eligible if they have evidence of active disease defined as one or more of the following signs/symptoms: Documented weight loss of ≥ 10% over a 6 month period; Febrile episodes of 38 degrees Celsius (100.5 degrees F) or greater for greater than 2 weeks without evidence of infection; Massive or progressive splenomegaly defined as > 6 cm below the left costal margin; Massive (> 10 cm in longest diameter) or progressive lymphadenopathy.
Patient has not received any prior treatment for CLL in the past.
Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2 at study entry
Laboratory test results within these ranges: Absolute neutrophil count ≥ 1000/mm³; Platelet count ≥ 50,000 /mm³; Renal function assessed by calculated creatinine clearance ≥ 30ml/min by Cockcroft-Gault formula; Total bilirubin ≤ 1.5 x upper limit of normal (ULN); aspartic transaminase (AST/SGOT) and alanine transaminase (ALT/SGPT) ≤ 2.5 x ULN; Alkaline phosphatase <2.5 x ULN
Disease free of prior malignancies for ≥ 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix or breast
All study participants must be registered into the mandatory REMS® program, and be willing and able to comply with the requirements of REMS®.
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 and again within 24 hours prior to prescribing lenalidomide for Cycle 1 (prescriptions must be filled within 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy.
Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (patients intolerant to acetylsalicylic acid (ASA) may use warfarin or low molecular weight heparin).
Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
Pregnant or breast feeding females. (Lactating females must agree not to breast feed while taking lenalidomide).
Any condition, including the presence of laboratory abnormalities, which places the patient at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study
Evidence of laboratory Tumor Lysis Syndrome (TLS) by Cairo-Bishop Definition. Patients may be enrolled upon correction of electrolyte abnormalities.
Use of any other experimental drug or therapy within 28 days of baseline
Known hypersensitivity to thalidomide
The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.
Any prior use of lenalidomide
Concurrent use of other anti-cancer agents or treatments
Known seropositive for or active viral infection with human immunodeficiency virus (HIV)
Positive serology for hepatitis B (HB) defined as a positive test for HBsAg. In addition, if negative for HBsAg but HBcAb positive and HBsAb negative, a HB DNA test will be performed and if positive the patient will be excluded. Note: If HBcAb positive and HBsAb positive, which is indicative of a past infection, the patient can be included. Patients who are seropositive because of hepatitis B virus vaccine are eligible. Consult with a physician experienced in care & management of subjects with hepatitis B to manage/treat subjects who are anti-HBc positive.
Positive serology for hepatitis C (HC) defined as a positive test for hepatitis C antibody (HCAb), in which case reflexively perform a HC recombinant immunoblot assay (RIBA) on the same sample to confirm the result
