Beginning in 2006, the AIM Dysplasia Trial enrolled 127 patients having a diagnosis of Barrett's esophagus with dysplasia, the most advanced stage of this condition. Patients were randomly assigned to receive either endoscopic ablation with the HALO system or a sham intervention (control, no treatment). Tissue samples (biopsies) were obtained from the esophagus at regular intervals for one year after enrollment to assess for the presence of early Barrett's, dysplasia, and esophageal cancer. Comparison of the biopsy results at one year served as the primary outcome for the trial. The study endpoints were the eradication of all early Barrett's and, separately, all dysplasia in each group, as well as occurrence of new esophageal cancers.
At one-year follow-up, patients treated with ablation had a significantly higher complete eradication rate for both early Barrett's and dysplasia as compared to the control group. More than three quarters of treated patients had no detectable Barrett's at the end of the treatment period, compared to sham patients where 98% had persistent disease. The overall rate of disease progression to more severe forms of dysplasia and cancer was significantly lower in the ablation treatment group (3.6%) as compared to the control group (16.3%). In the highest risk cohort (high-grade dysplasia), ablative therapy significantly reduced the risk of progression to cancer by nearly 90% compared to control (2.4% in treated patients versus 19.0% in untreated controls).
