Clinical Trial Summary

The majority of patients with CLL are diagnosed with early stage disease (Binet stage A or Rai stage 0/I). Standard management of such patients is observation, and with median age at diagnosis of 72 and median time to progression of >5-10 years, many will never require treatment. In contrast, a proportion of patients have more aggressive disease, and over the last decade, a number of molecular factors have been identified that may be used to identify patients with poor prognosis disease . Each is associated with shortened time to treatment (typically less than 3 years in patients with 2 of more factors), reduced survival, with in the case of p53/ATM inactivation, resistance to treatment. Whether it is possible to improve the outcome of patients with CLL and adverse prognostic factors by early intervention with treatment is unknown. Several trials in the 1980's demonstrated that treatment of stage A CLL with conventional chemotherapy (chlorambucil) did not alter the natural history of the disease, although none of these studies stratified patients according to risk. The choice of alternative potential therapeutic agents is limited; they should be effective in patients with adverse prognostic factors, have acceptable toxicity, be able to overcome the drug resistance associated with p53/ATM inactivation and ideally be orally administered. Two recent phase II trials have demonstrated that Lenalidomide is effective in the treatment of relapsed/refractory disease. Importantly, both studies included a high proportion of patients with adverse prognostic factors including p53 inactivation. The principle objective of this study is to investigate the efficacy of Lenalidomide in achieving disease response (complete remission and clearance of minimal residual disease) in patients with poor risk early stage disease, together with assessment of safety and tolerability.

• Female subjects of childbearing potential and all male subjects must agree to comply with the stipulations of the pregnancy prevention plan.

Exclusion Criteria:

• Current or recent (within the last 1 month) participation in another clinical trial investigating the action of an investigational medicinal product for the treatment of CLL

• Pregnant or lactating

• Known positivity for human immunodeficiency virus (HIV) types 1 or 2

• Prior history of malignancies, other than CLL, unless the subject was treated with curative intent and has been free of the disease for =3 years. Exceptions include the following:

• Basal cell carcinoma of the skin

• Squamous cell carcinoma of the skin

• Carcinoma in situ of the cervix

• Carcinoma in situ of the breast

• Significantly abnormal renal or hepatic function (creatinine clearance < 60ml/min, serum aspartate aminotransferase (AST) > 3 x upper limit of normal (ULN), serum bilirubin > 34µmol/l)

• Active autoimmune haemolytic anaemia or thrombocytopenia

• Any other medical or psychological condition that in the view of the investigator would be likely to impact compliance with the protocol or interfere with trial treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Complete Remission with clearance of Minimal Residual Disease (MRD)		6 months (or earlier if clinically indicated)	No
Secondary	Event free survival	Defined as interval from the first treatment day to the first sign of disease progression, treatment for relapse or death (whichever occurs first).	Treatment/ progression/ death details collected at all visits (6 visits per month in dose escalation, 1 visit per month in dose maintenance, annual in long-term follow-up)	No
Secondary	Safety & tolerability of treatment (occurrence of adverse events)	Adverse events will be monitored according to NCI CTCAE v3 from screening until 1 month after treatment discontinuation/ trial closure. Adverse event data will be captured at all visits (6 visits per month in dose escalation, 1 visit per month in dose maintenance). Adverse event data will be assessed by blood tests, physical exam/ vital signs and pregnancy testing.	Assessed at all visits (6 visits per month in dose escalation, 1 visit per month in dose maintenance, annual in long-term follow-up)	Yes
Secondary	Time to next treatment	Defined as interval between first treatment day on the study protocol to the first day of the next course of CLL therapy following disease progression.	Treatment details collected at all visits (6 visits per month in dose escalation, 1 visit per month in dose maintenance, annual in long-term follow-up)	No
