Abstract

Background: A 1 L PEG-based preparation for colonoscopy (NER1006) has been recently developed.Aims: We conducted a meta-analysis of randomized controlled trials (RCTs) to explore the effectiveness and safety of NER1006 versus traditional preparations.Methods: PubMed/Medline and Embase were systematically searched through January 2020 for phase-3 RCTs comparing NER1006 versus standard preparations.Results: Three RCTs (1879 participants) met the inclusion criteria and were included. The analysis showed a higher cleansing success for NER1006 compared standard preparations (OR=1.28; 95% CI 1.00-1.62; p = 0.047, I-2= 0%) as well as a greater high-quality cleansing of the right colon (OR= 2.13; 95% CI 1.16-3.94; p = 0.015, I-2= 76.0%) when assessed by the Harefield Cleansing Scale (HCS).The pooled estimate of the NER1006 effect on ADR showed a higher, although not significant, ADR of the right colon (OR= 1.19; 95% CI 0.73-1.92; p = 0.485, I-2 = 53%). When considering the impact of NER1006 on mild to moderate treatment-emergent adverse events (TEAEs), we observed a significant pooled estimate of TEAEs (OR= 2.31; 95% CI 1.82-2.94; p<0.001, I-2 = 0%).Conclusions: When compared to traditional preparations, NER1006 showed a better overall cleansing of the colon as well as a greater high-quality cleansing of the right colon, with comparable ADR. A higher incidence of mild to moderate TEAEs was observed for NER1006, in the absence of serious adverse events. (c) 2020 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.
