Study of Bendamustine, Lenalidomide and Low-dose Dexamethasone, for the Treatment of Patients With Relapsed Myeloma

2013年4月4日 更新者:Gruppo Italiano Studio Linfomi

A Phase I/II Study of Bendamustine, Lenalidomide and Low-dose Dexamethasone, (BdL) for the Treatment of Patients With Relapsed Myeloma.

This is an open Label, Phase I/II, multicenter study. In the first phase it defines the maximum tolerated dose (MTD) of Bendamustine (B) given in combination with Lenalidomide (L) and low-dose Dexamethasone (d) and in the second phase it evaluates the antitumour activity of Bendamustine, Lenalidomide and Low-dose Dexamethasone (BdL) given in combination, in relapsed multiple myeloma patients.

調査の概要

詳細な説明

Multiple myeloma is a B-cell malignancy resulting from the monoclonal proliferation of plasma cells within the bone marrow. According to the American Cancer Society, 14,600 new cases of multiple myeloma will be diagnosed in 2002, and these will account for approximately 1% of all new cancer cases. Multiple myeloma will contribute to 2% of all cancer deaths this year; an estimated 10,800 deaths will occur overall. The disease is more prevalent in men and is twice as common in African-Americans as in Caucasians. Multiple myeloma is commonly thought of as a disease of older patients; the median age at diagnosis is 68 years, and the incidence increases more than 4%/year in those older than 85 years. The median survival with standard treatment is only 3 years.

Therapeutic options for patients with multiple myeloma (MM) are rapidly changing. The emergence of two highly active novel agents, bortezomib and lenalidomide, have dramatically changed the landscape of treatment options and have improved outcomes for many patients. Combinations of conventional agents with novel agents have also demonstrated significant efficacy for patients with newly diagnosed and relapsed myeloma. Among the conventional agents that are being explored is the bifunctional alkylator agent bendamustine, which has demonstrated single-agent activity and activity with novel agents.

Lenalidomide is a new immunomodulating agent effective in multiple myeloma, especially when associated with dexamethasone or melphalan and prednisone. The role of lenalidomide in the treatment of relapsed/refractory patients with MM has been established and current research is focused on the combination of lenalidomide with chemotherapy to further improve results.

Bendamustine is a bi-functional alkylating agent with a purine- like benzimidazole ring that has been administered successfully to patients with MM. In vitro studies showed that bendamustine possesses a unique profile of activity, which was clearly divergent from other common nitrogen mustard drugs. Bendamustine and prednisone in newly diagnosed MM patients results in superior complete response rate, prolonged time to treatment failure and improved quality of life compared to treatment with melphalan and prednisone. The role of bendamustine, thalidomide and prednisolone (BPT) in patients with relapsed or refractory diseases stage II/III has been investigated by the East German Study group of Hematology and Oncology (OSHO). The response rate was higher than 80%.

Despite the impressive efficacy of the lenalidomide/dexamethasone in relapsed MM, treated patients will eventually relapse (median Time to Progression (TTP) is expected to be nearly a year according the results of the two phase III randomized studies). Combination with an effective novel agent as bendamustine could further increase both the response rate and the TTP of lenalidomide/dexamethasone and induce durable responses in relapsed or refractory MM patients. The identification of an appropriate lenalidomide dose to be adopted in combination with bendamustine and dexamethasone and the generation of exploratory data on the efficacy of this novel combination appears to be important in terms of future development of even more effective treatments of MM.
