To improve patient experience, a new sports drink-flavored bowel preparation containing polyethylene glycol (PEG) and sulfate salts (FPSS) was developed to provide a similar experience to a commonly used but not United States Food and Drug Administration (FDA) approved PEG and sports drink bowel preparation (PEG-SD), while also achieving improved cleansing efficacy.
METHODS: This FPSS preparation, approved by the FDA in June 2023, was evaluated in a non-randomized Phase 2 study in which 40 patients requiring colonoscopy were prepared with FPSS and 20 with PEG-SD.
RESULTS: Overall cleansing success was high with FPSS based on unblinded local endoscopist assessment (93%) and blinded central reading (97%), exceeding PEG-SD which achieved success rates of 84% (local read), 74% and 68% (blinded central reads). Similar differences favoring FPSS were seen for excellent preparations and cleansing success by colon segment as rated by local endoscopists. Both preparations were well-tolerated, with 93% of FPSS patients rating their preparation as Tolerable to Very Easy to consume, compared to 100% of PEG-SD. Patients who had previously taken a preparation for colonoscopy found FPSS and PEG-SD better than their prior preparation (73% and 70%, respectively) and nearly all would request their assigned study preparation again in the future. About two thirds of FPSS patients agreed that the preparation tasted similar to a sports drink.
CONCLUSIONS: The new sports drink-like flavored preparation compares favorably to PEG-SD for bowel cleansing efficacy while achieving similar patient satisfaction. The study was registered at www.
