Trial Outcomes & Findings for Lenalidomide, Cyclophosphamide, and Dexamethasone in Treating Patients With Primary Systemic Amyloidosis (NCT NCT00564889)

NCT ID: NCT00564889

Last Updated: 2013-05-14

Results Overview

Response that was confirmed on 2 consecutive evaluations during treatment. Complete Response(CR): Complete disappearance of M-protein from serum and urine on immunofixation, normalization of Free Light Chain (FLC) ratio and \<5% plasma cells in bone marrow. Very Good Partial Response(VGPR): \>=90% reduction in serum M-component; Urine M-Component \<=100 mg per 24 hours. Partial Response(PR): \>=50% reduction in serum M-component and/or Urine M-Component \>=90% reduction or \<200 mg per 24 hours; or \>=50% decrease in difference between involved and uninvolved FLC levels.

21 participants

SECONDARY outcome

Timeframe: Duration of study (up to 3 years)

Organ response was evaluated on the basis of improvement of one or more affected organ; only one parameter was required to satisfy the criteria. Response needed to be maintained for a minimum of 3 months to be considered valid. Renal response required a 50% reduction in 24-hour urine protein excretion (at least 0.5 g/d) with stable creatinine. Cardiac response required one of \>= 2-mm reduction in the interventricular septal (IVS) thickness by echocardiogram, or improvement of ejection fraction by \>= 20%, or improvement by 2 NYHA classes without an increase in diuretic use. Hepatic response required either \>= 50% decrease in (or normalization of) an initially elevated alkaline phosphatase level or reduction in the size of the liver by at least 2 cm by radiographic determination. Gastrointestinal tract improvement was defined as normalization of a low serum carotene level, or reduction of diarrhea to \< 50% of previous movements/day, or decrease in fecal fat excretion by 50%.

SECONDARY outcome

Timeframe: Duration of study (up to 3 years)

Severe adverse events were defined as grade 3 or higher, at least possibly related to study drugs. Adverse events were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.

SECONDARY outcome

Timeframe: Duration of study (up to 3 years)

Progression free survival (PFS) was defined as the time from registration to hematologic progression or death of any cause. Progression free and alive patients were censored at the date of last follow-up. The median PFS with 95% CI was estimated using the Kaplan Meier method.
