About

The purpose of this study is to determine the effectiveness and safety of NASHA/Dx when used as an injectable bulking agent in the treatment of fecal incontinence. The study includes a 6-month blinded sham-controlled phase, followed by an open-label phase.

Full description

Subjects will be given up to 2 treatments of NASHA/Dx or sham and followed for 6 months from last treatment (ie, one retreatment is permitted at 1 month after the first injection) in the blinded phase of the study. At Month 6, the open phase of the study will begin and subjects on sham will be offered open-label treatment with NASHA/Dx.

Subjects who receive NASHA/Dx at the start of the blinded phase will be followed for up to 36 months from last treatment in the blinded phase. Subjects who receive sham at the start of the blinded phase and then receive open-label NASHA/Dx at Month 6 (start of the open phase) will be followed for another 24 months (equivalent to approximately 30 months from randomization) from last treatment in the open phase of the study.

206 participants in 3 patient groups

Blinded injection of NASHA/Dx gel at randomization.
Experimental group
Description:
Blinded injection of NASHA/Dx (Solesta) Gel. For each treatment, a series of 4 equally spaced injections with 1 mL of Solesta into the anal canal. Subjects will be followed for 6 months during the blinded phase. During a subsequent open phase, these subjects will be followed to Month 36 (ie, for an additional 30 months).
Treatment:
Device: NASHA/Dx (Solesta) Gel
Blinded sham inject. at randomization
Sham Comparator group
Description:
Blinded sham injection (needle stick with empty syringes). For each treatment, a series of 4 equally spaced Sham injections (needle sticks) into the anal canal. Subjects will be followed for 6 months during the blinded phase. Sham-treated subjects have the option to receive open-label injection of NASHA/Dx (Solesta) Gel at the 6-month time point following completion of the blinded phase (ie, blinded sham injection at randomization + NASHA/Dx Gel at 6 months). Following injection of NASHA/Dx gel at the start of the open phase, these subjects will be followed to Month 30 (ie, for an additional 24 months).
Treatment:
Device: Sham Injection
Blinded Sham Inject. at Randomization + NASHA/Dx Gel at 6 mo.
Other group
Description:
Blinded sham injection at randomization. Subjects will be followed for 6 months during the blinded phase. Sham-treated subjects have the option to receive open-label injection of NASHA/Dx (Solesta) Gel at the 6-month time point following completion of the blinded phase (ie, blinded sham injection at randomization + NASHA/Dx Gel at 6 months). Following injection of NASHA/Dx gel at the start of the open phase, these subjects will be followed to Month 30 (ie, for an additional 24 months).
Treatment:
Device: Sham Injection
Device: NASHA/Dx (Solesta) Gel
