Trial Outcomes & Findings for The CHARM Trial: Chemotherapy for Ablation and Resolution of Mucinous Pancreatic Cysts (NCT NCT01475331)

NCT ID: NCT01475331

Last Updated: 2018-03-20

Results Overview

The primary outcome of interest will be change in cyst size, as measured on initial, 6, and 12 month CT/MRI, or as determined necessary to evaluate cyst resolution. Cyst size was calculated by measuring x and y diameters and calculating cyst volume using the formula:4/3xpxr3 where r is the average of the cyst radius as measured on the initial, 6-month, and 12-month magnetic resonance imaging or computed tomography. Response was defined according to the same volume percentage reductions as described in previous trials where: complete response is a =\>95% reduction in cyst volume, partial response is a 94%-75% reduction, and anon-response is \<75% reduction in volume.11 The overall ablation rates in both arms were also compared with historical controls to assess the efficacy of the chemotherapeutic cocktail.

Cyst will be lavaged for 3-5 minutes with Ethanol (alcohol 80%). Following lavage with Ethanol (alcohol 80%), The cyst will be infused with an admixture of(Paclitaxel/ Gemcitabine) 3mg/ml paclitaxel and 19mg/ml gemcitabine. Ethanol: Cysts will be lavaged for 3-5 minutes with 80% EtOH Chemotherapy: Following lavage with either 80% ethanol (control group) or normal saline (study group), cysts will be injected with a cocktail of 3mg/ml paclitaxel and 19mg/ml gemcitabine.
