Efficacy: Quality Score of bowel preparation with Boston Bowel Preparation Scale (BBPS) |
Eficacia: Puntuación de limpieza global de la Escala de Preparación Intestinal de Boston (BBPS). |

E.5.1.1 | Timepoint(s) of evaluation of this end point |
During the colonoscopy |
Durante la colonoscopia |
|
E.5.2 | Secondary end point(s) |
Efficacy: - Proportion of patients with 'adequate' cleansing for the right colon segment (segment score > or = to 2). - Proportion of patients with 'adequate' cleansing for the transverse colon segment (segment score > or = to 2). - Proportion of patients with 'adequate' cleansing for the left colon segment (segment score > or = to 2). - Proportion of completed colonoscopies (intubation of the cecum) and proportion of rescheduled colonoscopies. - Relationship of the BBPS score and the percentage of patients who completed the colonoscopy (intubation of the cecum). - Polyps detection rate (percentage of patients with at least one polyp detected). - Polyps detection rate by location (colon segment). - Mean number of polyps per patient detected per size (< 5 mm / 5-<10 mm / > or = to 10 mm).
Acceptability: - Proportion of patients with 'very acceptable' acceptability, based on a 4-points Likert scale. - Proportion of patients willing to repeat the same bowel preparation. - Proportion of patients who assessed the product taste as 'no taste', based on a 4-points Likert scale. - Proportion of patients who assessed the easiness to take the product as 'easy', based on a 4-points Likert scale.
Tolerability: - Proportion of patients experiencing nausea, vomiting, abdominal pain, abdominal bloating. - Severity of nausea, vomiting, abdominal pain, abdominal bloating using a 4-point Likert scale.
Compliance: - Patient's compliance based on the assessment of study drug intake.
Safety: Proportion of patients with TEAEs by System and Organ Class (SOC) and Preferred Term (PT) using MedDRA terminology. Diarrhoea is an expected outcome of study drug with bowel preparation, will not be captured as an adverse event unless it is a serious adverse event. It is also expected that some cancers will be detected during colonoscopy; these will not be considered as serious adverse events. Polyps and diverticuli found during the colonoscopy will not be considered as adverse events, because they are part of the objectives of the colonoscopy. |
Eficacia: - Proporción de pacientes con limpieza 'adecuada' del segmento derecho del colon (puntuación del segmento > o = 2). - Proporción de pacientes con limpieza 'adecuada' del segmento transverso del colon (puntuación del segmento > o = 2). - Proporción de pacientes con limpieza 'adecuada' del segmento izquierdo del colon (puntuación del segmento > o = 2). - Proporción de colonoscopias completas (intubación cecal) y proporción de colonoscopias reprogramadas. - Relación entre la puntuación BBPS y el porcentaje de pacientes que hayan completado la colonoscopia (intubación cecal). - Tasa de detección de pólipos (porcentaje de pacientes con al menos un pólipo detectado) - Tasa de detección de pólipos por localización (segmento del colon). - Número medio de pólipos por paciente detectados por tamaño (< 5 mm / 5-<10 mm / > o = 10 mm).
Aceptabilidad: - Proporción de pacientes con una aceptabilidad 'muy aceptable', basada en una escala Likert de 4 puntos. - Proporción de pacientes que deseen repetir la misma preparación intestinal. - Proporción de pacientes que evalúen el sabor del producto como 'sin sabor', basado en una escala Likert de 4 puntos. - Proporción de pacientes que evalúen la facilidad de tomar el producto como 'fácil', basado en una escala Likert de 4 puntos.
Tolerabilidad: - Proporción de pacientes que presenten nausea, vómitos, dolor abdominal, inflamación abdominal. - Intensidad de la náusea, vómitos, dolor abdominal, inflamación abdominal usando una escala Likert de 4 puntos.
Cumplimiento: - El cumplimiento de los pacientes se basa en la evaluación de la ingesta de la medicación del estudio.
Seguridad: Proporción de pacientes con TEAEs por sistema orgánico (SOC) y término preferente (PT) usando la terminología MedDRA. No se registrará la diarrea como acontecimiento adverso a no ser que se trate de un acontecimiento adverso grave, ya que es una consecuencia lógica de la medicación del estudio en la preparación intestinal. Los pólipos o diverticulitis encontrados durante la colonoscopia no se considerarán acontecimientos adversos, porque son parte de los objetivos de la colonoscopia. Asimismo se espera que se detecten algunos cánceres durante la colonoscopia; éstos no se considerarán como acontecimientos adversos graves. |
