Ofatumumab With High Dose Methylprednisone Followed by Ofatumumab and Alemtuzumab in 17p CLL
A Phase II Study of Ofatumumab-High Dose Methylprednisolone Followed by Ofatumumab-Alemtuzumab in 17p Deletion CLL
Study Overview
Status
Intervention / Treatment
Detailed Description
Participants were assigned to 1 of 2 groups based on prior treatment status. Both groups received the same therapy.
Part A: Ofatumumab + HDMP 2-4 cycles Part B: Ofatumumab + Alemtuzumab 1-6 cycles Part C: Maintenance with Ofatumumab + Alemtuzumab up to 2 years
Between days 15-22 of Cycle 2 of Part A, participants are restaged. Participants who achieve nodal complete response discontinue Part A therapy and undergo minimal residual disease (MRD) assessment to guide the decision whether to go to Part B or Part C. The participants with persistent disease after 2 cycles of Part A therapy receive 2 more cycles of Part A therapy and then undergo another restaging as well as MRD assessment. At restaging, participants with minimal disease are eligible for Part C or allogeneic stem cell transplant (SCT) off protocol. The remaining participants receive Part B therapy. On Part B, restaging occurs at weeks 12 and 18. If MRD negative complete response (CR) status is achieved then therapy is discontinued and the primary endpoint evaluation occurs 2 months later. Otherwise with persistent disease Part B therapy continues up to 24 weeks and the primary endpoint evaluation occurs after Part B therapy is completed. Participants who achieve clinical complete response may receive Part C therapy or be observed while waiting SCT.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Induction Overall Response Rate (ORR)
Time Frame: Disease was evaluated after weeks 8 and 16 of Part A and at 12, 18 and 24 weeks during part B.
|
Induction ORR is the percentage of participants achieving a minimum of partial response (PR) over induction treatment based on International Workshop on Chronic Lymphocytic Leukemia (IW-CLL) criteria (Hallek, et al 2008).
There are numerous diagnostic tests used for response evaluation including potentially CBC and differential count, marrow aspirate and biopsy, ultrasound of the abdomen, CT scans (chest, pelvis, abdomen) and physical examination.
PR is a 50% or greater decrease of measured size of lymphadenopathy, hepatomegaly, splenomegaly as well as blood lymphocytes (over baseline), marrow infiltrate or B-lymphoid nodules and a 50% or greater increase from baseline in platelet count (or level >100,000/micro liter), hemoglobin (or level >11 grams/deciliter), neutrophils (or level >1500/microliter).
