A Phase 2 interventional study of High Dose Methylprednisolone (HDMP) and Ofatumumab in Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma, sponsored by H. Lee Moffitt Cancer Center and Research Institute. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-12-19.

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.
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.

Number of Participants With Complete Response (CR)
Number of participants with complete response, the disappearance of all signs of cancer in response to treatment.
Time frame: 3 Months
Number of Participants With Partial Response (PR)
The primary endpoint for this trial is the combined complete and partial response rate to the protocol therapy at 3 months, which is also the end of Cycle 3. The objective response (CR+PR) rate will be summarized using both a point estimate and its exact confidence interval based on the binomial distribution.
Time frame: 3 Months
Rate of Progression/Relapse Free Survival (PFS)
Progression-free survival (PFS), defined as the time from study entry to disease progression, relapse or death due to any cause, whichever is earlier.
Time frame: Up to 56 months
Number of Participants With Overall Survival (OS)
Overall survival will be summarized with the Kaplan-Meier curve.
Time frame: 36 Months
