Phase 3 |
Detailed Description
This study was designed according to the 18F-florbetaben positron emission tomography imaging, which successfully demonstrated a significant reduction in the amount of amyloid in the heart when administered by merging thalidomide and dexamethasone in patients involving myocardium, and reported that this reaction leads to an improvement in cardiac function. Amyloid light-chain amyloidosis patients at age 19 or older with refractory or relapsed who participants should have never been exposed to lenalidomide within 5 years. Planned initial dosage of the current regimen are as follow;
-
Lenalidomide : D1~D21 daily oral administration, starting dose 15mg, with an increase of 5mg every cycle, if tolerated, up to 25mg.
-
Dexamethasone : D1~D4 daily oral administration or intravenous injection, 40mg(or 20mg for age for age ≥ 65 years old) Patients will be treated every 4 weeks as one cycle, and up to 12 cycles of treatment will be conducted. The investigator is working on a total of 30 patients, the primary endpoint of this study is objective response rate and secondary endpoints are cardiac/renal/hepatic function, 18F-florbetaben positron emission tomography imaging parameter, overall survival period, progression-free survival period, toxicity profile.

Outcome Measures
Primary Outcome Measures
- Objective response rate (ORR) [After completion of 12 cycles of treatment(each cycle is 28 days)]
ORR is defined as the percentage of subjects with evidence of a confirmed CR(complete response), VGPR(very good partial response) or PR(partial response)
Secondary Outcome Measures
- Change of the cardiac function [At Baseline and the end of each 1-12 cycles (baseline and 1-12 months)]
Change of the cardiac function will be observed with the NTproBNP levels.
- Change of the renal function [At Baseline and the end of each 1-12 cycles (baseline and 1-12 months)]
Change of the renal function will be observed with the 24h urine protein levels.
- Change of the hepatic function [At Baseline and the end of each 1-12 cycles (baseline and 1-12 months)]
Change of the hepatic function will be observed with the alkaline phophatase levels.
