简要总结
This study is mainly assessing the safety of Revlimid in combination with Ancestim (recombinant human stem cell factor) in patients with symptomatic myelodysplasia. Of those two compounds, Revlimid has been shown to be an active drug in myelodysplasia. Clinical responses will also be assessed.
详细描述
Aim: The primary objective is to assess the safety of Revlimid in combination with Ancestim in patients with symptomatic myelodysplasia. The secondary objectives are: Duration of response and assessment of changes in gene expression profile of bone marrow samples from patients undergoing such treatment.
Potential Significance: Myelodysplastic syndromes (MDS) are malignant hematopoietic stem cell disorders. Prognosis can be estimated by use of the International Prognostic Scoring System (IPSS) which divides patients into low, intermediate-1, intermediate-2, and high-risk groups with corresponding median survival times of 5.7 years, 3.5 years, 1.2 years, and 0.4 years, respectively. There is currently no standard treatment for MDS and management is often purely symptomatic with transfusion of blood products and antibiotic treatment of infections.
A recent phase II study however has shown significant response rates with Revlimid as a single agent in patients with MDS. The total response rate was 56%. The effects of Revlimid and SCF on hematopoietic progenitors cells were examined in vitro. RhSCF and Revlimid were shown to be synergistic in stimulating the proliferation of hematopoietic progenitor cells and their precursors in vitro, thereby forming the rationale for this study.
Research Plan: This is a single-centre, open label, single-arm, non-comparative study, in which 25 patients will be enrolled. The study will include patients who meet all the inclusion and none of the exclusion criteria, as per the respective protocol section.
The patients will be enrolled sequentially to receive 2 different dose levels of Ancestim with a fixed dose of Revlimid. This will determine the feasibility and tolerability of the combination of Revlimid and Ancestim. Patients will start with an 8 week course of single agent Revlimid as 10mg daily oral treatment day 1-21 in a 28 day cycle. If patients do not achieve a complete remission on single agent Revlimid they will start on Ancestim s.c. injections. Two dose levels of Ancestim (10 and 20 mcg/kg s.c. daily for 7 days) will be evaluated.
