- Number of Participants With Complete Response (CR) [ Time Frame: 3 Months ]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.
- Number of Participants With Partial Response (PR) [ Time Frame: 3 Months ]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.
- Number of Participants With Progression/Relapse Free Survival (PFS) [ Time Frame: 36 Months ]Progression-free survival (PFS), defined as the time from study entry to disease progression, relapse or death due to any cause, whichever is earlier, will be summarized with the Kaplan-Meier curve. Confidence intervals for the median and survival rates at different time points will be constructed if needed.
- Number of Participants With Overall Survival (OS) [ Time Frame: 36 Months ]Overall survival will be summarized with the Kaplan-Meier curve.

The Lenalidomide Starting Dose (Cycle 4) Based on Renal Function Prior to Cycle 4 of Treatment.
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.
