Ofatumumab, High Dose Methylprednisolone, Ofatumumab and Lenalidomide Consolidative Therapy for Untreated CLL/SLL

Chronic Lymphocytic Leukemia Clinical Trial

Official title: Phase II Study of Ofatumumab in Combination With High Dose Methylprednisolone Followed by Ofatumumab and Lenalidomide Consolidative Therapy for the Treatment of Untreated CLL/SLL The HiLOG Trial

Status Active, not recruiting

Clinical Trial Summary

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 (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.

Clinical Trial Description

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. ;
