Abstract

Background: Fecal incontinence affects 7% to 12% of the US adult population, causing social, financial, and quality of life burdens.

Objective: The primary aim of this study was to evaluate the efficacy and safety of nonanimal stabilized hyaluronic acid/dextranomer through 36 months as a condition of postmarket approval application.

Design: This was a prospective, single-arm, multicenter, observational Food and Drug Administration-mandated postapproval clinical study.

Settings: This study was designed and executed by participating centers in 18 hospitals and colorectal health clinics in coordination with the Food and Drug Administration and the study sponsor.

Patients: A total of 283 subjects who previously failed conservative therapy were enrolled across 18 US sites.

Interventions: Participants received 1 to 2 nonanimal stabilized hyaluronic acid/dextranomer treatments. The first treatment occurred within 30 days of baseline, and a second treatment was administered 1 to 3 months after initial treatment if determined necessary by the physician. Subjects were followed through 7 visits over 36 months after last treatment.

Main outcome measures: Efficacy (as specified by the Food and Drug Administration) was measured as a fecal incontinence reintervention rate of <50% at 36 months. Reintervention included nonanimal stabilized hyaluronic acid/dextranomer re-treatment, surgical interventions, and physical therapy. Safety was measured by device-related adverse events. Secondary end points included Fecal Incontinence Quality of Life Scale and Cleveland Clinic Florida Fecal Incontinence Score.

Results: Using a Bayesian estimate, the reintervention rate of the intention-to-treat population (n = 283) was 18.9% (95% CI, 14.0-24.4) at 36 months. At 36 months, the reintervention rate for subjects with complete data (n = 192) was 20.8% (95% CI, 15.1-26.6). Significant improvement ( p < 0.0001) was noted across the Cleveland Clinic Florida Fecal Incontinence Score and Fecal Incontinence Quality of Life subscales at 36 months. Ninety-two device-related adverse events were reported by 15.2% of enrolled patients; most were GI disorders and resolved quickly. There were no serious adverse events.

Limitations: Limitations of the study included a 32% attrition rate and homogeneous patient population (91.8% white; 85.5% female), possibly limiting generalizability.

Conclusions: Nonanimal stabilized hyaluronic acid/dextranomer demonstrated clinically significant, sustained improvement in symptoms and quality of life for fecal incontinence patients without the occurrence of any serious adverse events. See Video Abstract at http://links.lww.com/DCR/B890 .

Eficacia y seguridad de un cido hialurnico/ dextranmero estabilizado de orgen no animal para mejorar la incontinencia fecal un estudio clnico prospectivo, multicntrico y de un solo brazo con seguimiento de meses: ANTECEDENTES:La incontinencia fecal afecta entre el 7 y el 12% de la población adulta de los EE. UU. Y genera cargas sociales, económicas y de calidad de vida.OBJETIVO:Los objetivos principales de este estudio fueron evaluar la eficacia y seguridad del ácido hialurónico/ dextranómero estabilizado de origen no animal durante 36 meses como condición para la solicitud de aprobación posterior a la comercialización.DISEÑO:Este fue un estudio clínico prospectivo, observacional, de un solo brazo, multicéntrico, ordenado por la FDA después de la aprobación.AJUSTES:Este estudio fue diseñado por los investigadores participantes, la FDA y el patrocinador del estudio que gestionó la recopilación de datos.PACIENTES:Un total de 283 sujetos en quienes previamente falló la terapia conservadora se inscribieron en el estudio prospectivo de un solo brazo en 18 sedes de EE. UU. (NCT01647906).INTERVENCIONES:Los participantes recibieron 1-2 tratamientos con ácido hialurónico/ dextranómero estabilizado no animal. El primer tratamiento se dio dentro de los 30 días posteriores al inicio, mientras que un segundo tratamiento se administró 1-3 meses después del tratamiento inicial si el médico lo determinaba necesario. Los sujetos fueron seguidos durante 7 visitas durante 36 meses después del último tratamiento.PRINCIPALES MEDIDAS DE RESULTADO:La eficacia (según especificado por la FDA) se midió como una tasa de reintervención de incontinencia fecal de <50% a los 36 meses. La reintervención incluyó retratamiento con ácido hialurónico/ dextranómero estabilizado no animal, intervenciones quirúrgicas y fisioterapia. La seguridad se midió mediante los eventos adversos relacionados con tratamiento. Los criterios de valoración secundarios incluyeron la escala de calidad de vida de incontinencia fecal y la puntuación de incontinencia fecal de Cleveland Clinic Florida.RESULTADOS:Utilizando una estimación bayesiana, la tasa de reintervención de la población por intención de tratar (n = 283) fue del 18.9% (IC del 95%: 14.0%, 24.4%) a los 36 meses. A los 36 meses, la tasa de reintervención para los sujetos con datos completos (n = 192) fue del 20.8% (IC del 95%: 15.1%, 26.6%). Se observó una mejora significativa (p <0.0001) en las subescalas de la puntuación de incontinencia fecal de la Cleveland Clinic Florida y de la calidad de vida de la incontinencia fecal a los 36 meses. El 15.2% de los pacientes inscritos informaron 92 eventos adversos relacionados con el tratmiento; la mayoría eran trastornos gastrointestinales y se resolvieron rápidamente. No hubo eventos adversos graves.LIMITACIONES:Las limitaciones incluyen una tasa de deserción del 32% y una población de pacientes homogénea (91.8% blancos, 85.5% mujeres), lo que posiblemente limite la generalización.CONCLUSIÓNES:El ácido hialurónico/ dextranómero estabilizado de origen no animal demostró una mejora sostenida y clínicamente significativa de los síntomas y la calidad de vida de los pacientes con incontinencia fecal, sin que se produjeran efectos adversos graves.
