Prevention of Disease Progression in Early Stage Indolent B Cell Malignancies. (SMM)

Phase 2TerminatedNCT00899353

Marshall University16 enrolled

Overview

Escalating doses of Omega 3 Fatty Acids are being used in patients who have early stage Chronic Lymphocytic Leukemia (ES-CLL), Monoclonal Gammopathy of Undetermined Significance (MGUS), or Smoldering Multiple Myeloma (SMM), whose disease does not currently require treatment. The primary aim of the study is to determine if the Omega 3 supplementation will help prevent or delay progression of the disease to a stage that requires treatment.

Outcomes

Primary Outcomes

Activated Nuclear Factor Kappa B (NFkB) in Peripheral Blood Lymphocytes From Patients With Early Stage Chronic Lymphocytic Leukemia (CLL) Before, During and After Consumption of an Omega 3 Supplement.

Peripheral lymphocytes were isolated from the blood using Ficoll-Paque gradient. Nuclear Factor Kappa B activation was analyzed using Thermo Scientific Transcription Factor kit for NFkB p50, according to manufacturer's protocol. Protein extracts containing 1-15µg of protein/well were added in triplicates. Luminescence resulting from a reaction with bound NFkB was detected using a Berthold Centro LB960 Luminometer and analyzed with MikroWin 2000 ver. 1.08. NFkB activity was normalized by luminescence units/µg of protein per well.

Time frame: baseline, and post supplement month 1(3 capsules/day), month 2 (6capsules/day), month 3 (9 capusules/day), month 6 (9 capusules/day), month 9 (9 capusules/day), month 12 (post supplement)

The Degree of Change in Tumor Mass Measurements During and After Omega-3 Supplementation as Evaluated by Standard Clinical Tests of Disease Activity.

Patients diagnosed with early stage (asymptomatic) CLL were supplemented with escalating doses of omega-3 (n-3) fatty acids (2.4 g of n-3/day up to 7.2 g of n-3/day). Given that these patients are asymptomatic and did not require treatment, measures of tumor mass during and after omega-3 supplementation, as evaluated by standard clinical tests of disease activity, were not performed. Instead, absolute lymphocyte counts (ALC), as a measure of tumor burden, was evaluated before and after omega-3 supplementation. Data represents the fold change in ALC post omega-3 consumption as compared to baseline ALC. Patients with MGUS or SMM were not enrolled into this study.
