Study information

Scientific title

A single arm phase II study to investigate the use of Lenalidomide in the treatment of patients with early stage chronic lymphocytic leukaemia (CLL) associated with poor prognostic factors

Acronym

RESPeCT

Study hypothesis

The majority of patients with chronic lymphocytic leukaemia (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 greater than 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 two or 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.

As of 02/05/2012, the anticipated end date of trial has been updated from 01/04/2012 to 24/11/2011.

Condition

Topic: National Cancer Research Network; Subtopic: Haematological Oncology; Disease: Leukaemia (chronic)

Intervention

Oral lenalidomide at escalating dose for 3 x 28 day cycles (2.5 mg daily, 5 mg daily, 10 mg daily), then maintenance phase at 10 mg (or maximum tolerated dose).

Intervention type

Drug

Phase

Phase II

Drug names

Lenalidomide

Primary outcome measures

Complete remission with clearance of minimal residual disease (MRD). Response to treatment to be assessed continually, with a more detailed assessment after 6 months of treatment (or earlier if clinically indicated). For patients in complete remission clearance of MRD is assessed every 6 months.

Secondary outcome measures

1. Safety and tolerability of treatment, assessed continually throughout treatment by collection of adverse event data, blood results, etc.
2. Event free survival, assessed each time patients are seen - at least once per month during treatment with study drug and then annually once off study drug and in long-term follow-up
3. Time to next treatment, assessed each time patients are seen - at least once per month during treatment with study drug and then annually once off study drug and in long-term follow-up
