Dextranomer in stabilized sodium hyaluronate (Solesta®): in adults with faecal incontinence.

Dextranomer in stabilized sodium hyaluronate, hereafter referred to as dextranomer/hyaluronic acid, is a biocompatible bulking agent administered by submucosal injection. It is hypothesized to expand the submucosal layer of the proximal anal canal, thereby augmenting bowel control. Treatment with dextranomer/hyaluronic acid was associated with symptomatic improvements in adult patients with faecal incontinence participating in a randomized, double-blind, sham-controlled, multinational study and a noncomparative, multinational study. In the double-blind study, patients in the dextranomer/hyaluronic acid group met the primary efficacy objective in that a significantly higher proportion of patients responded to treatment (≥50% reduction from baseline in the number of incontinence episodes) at the 6-month post-treatment timepoint than in the sham group (two of three primary response criteria), with the durability of the treatment response (≥25% reduction from baseline in the number of incontinence episodes) confirmed at the 12-month post-treatment timepoint (third primary response criterion). For the most part, dextranomer/hyaluronic acid did not significantly differ from the sham treatment in terms of quality of life and various other symptomatic endpoints at 6 months post-treatment in the double-blind study, although there were significant improvements from baseline in various parameters, such as the mean number of incontinence-free days, the median number of incontinence episodes and mean Faecal Incontinence Quality of Life domain scores, at 12 months post-treatment. In general, dextranomer/hyaluronic acid was well tolerated for up to 18 months post-treatment, with the majority of treatment-related adverse events considered mild or moderate in intensity.
