Description

plecanatide: A uroguanylin analog and guanylate cyclase (GC-C receptor) agonist that activates receptors on gut epithelial cells to maintain barrier function, mucus production, and suppress inflammation. It is used in the treatment of chronic idiopathic constipation and other gastrointestinal disorders. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

Research Excerpts

Overview

Plecanatide is a pH-sensitive uroguanylin analog that increases fluid and ion movement into the gastrointestinal lumen, softening stools and encouraging motility. It is a well-tolerated treatment that relieved the symptoms of CIC with a relatively low incidence of diarrhea.

Changes From Baseline Overall in Bristol Stool Form Scale (BSFS)

Using a Daily Diary, patients recorded Stool Consistency using the 7-point Bristol Stool Form Scale (BSFS) (1 = separate hard lumps, like nuts; 2 sausage shaped but lumpy; 3 = like a sausage but with cracks on surface; 4 = like a sausage or snake, smooth and soft; 5 = soft blobs with clear-cut edges; 6 = fluffy pieces with ragged edges, a mushy stool; 7 = watery, no solid pieces, entirely liquid). Changes in mean BSFS were assessed from the average 14-day pretreatment baseline to the average during the 2-week treatment period. (NCT01053962)

Change From Baseline Overall in Number of Complete Spontaneous Bowel Movements (CSBM)

Using a Daily Diary, patients recorded the number of spontaneous bowel movements having the sensation of complete evacuation (Complete Spontaneous Bowel Movement - CSBM). The total number of spontaneous bowel movements associated with a feeling of complete evacuation were summed and divided by 2 (the number of weeks in treatment). Change was calculated as the difference between the number of the CSBMs at the completion of the 2-week treatment period, versus the 14-day pretreatment baseline. (NCT01053962)

Overall Responder 9/12 Weeks

A Complete Spontaneous Bowel Movement (CSBM) is a Bowel Movement (BM) that occurs in the absence of laxative use within 24 hours of the BM and the patient reports a feeling of complete evacuation. A weekly responder will have 3 or more CSBMs and an increase of at least one CSBM from baseline in the same week. An overall responder is a patient who is a weekly responder for at least 9 of the 12 treatment weeks, including at least 3 of the last 4 weeks. (NCT01429987)

Change From Baseline in Straining

Change from baseline in Straining Score over the 12-week treatment period. Baseline was the mean of non-missing straining scores recorded during the 2-week baseline diary assessment period prior to the first dose of study drug. The severity of straining during a bowel movement was measured using an 11-point scale (0-10 rating; 0 = no straining; 10 = worst straining). (NCT02493452)
Timeframe: Baseline and 12-Week

Number of Sustained Efficacy Responders

A Sustained Efficacy Responder was a patient who was an Overall Responder who also was a Weekly Responder, i.e., decreased of 30% from baseline for abdominal pain intensity and increased of at least one CSBM (complete spontaneous bowel movement) in the same week for at least 2 of the 4 weeks in month 3 of the Treatment Period. (NCT02493452)
Timeframe: 12 Weeks

Change From Baseline in the Weekly Rate of Spontaneous Bowel Movements (SBM)

The weekly Spontaneous Bowel Movement (SBM) totals were derived from the daily diary entries reported during the Treatment Period in the Bowel Movement (BM) and symptom diaries. Baseline was the mean number of SBMs recorded during the 2-week baseline diary assessment period prior to the first dose of study drug. SBM is defined as a bowel movement that occurs in the absence of laxative use within the preceding 24 hours (NCT03120520)
Timeframe: 8 weeks

Change From Baseline in Weekly Average Stool Consistency Bristol Stool Form Scale (BSFS) Score

Stool consistency was assessed via the 7-point (1-7) Bristol Stool Form Scale (BSFS) and recorded in the bowel movement (BM) and Symptom Diaries. Lower numbers represent more formed stools; higher numbers represent less formed stools. The weekly mean BSFS score per patient = (total of all BSFS scores reported for a corresponding Spontaneous Bowel Movement (SBM) per time period)/n, where n = number of SBMs scored during the time period. Baseline was the mean BSFS score recorded during the 2-week baseline diary assessment period prior to the first dose of study drug. BSFS types were 1) separate hard lumps, like nuts (hard to pass); 2) sausage-shaped but lumpy; 3) like a sausage but with cracks on its surface; 4) like a sausage or snake, smooth and soft; 5) soft blobs with clear-cut edges (passed easily); 6) fluffy pieces with ragged edges, a mushy stool; 7) watery, no solid pieces, entirely liquid.

Proportion of Overall Responders

An Overall Responder is a participant who was a Spontaneous Bowel Movement (SBM) responder for the last 2 weeks of the Treatment Period. An SBM responder is defined as a participant who had >3 SBMs per week. SBM was defined as a bowel movement that occurs in the absence of laxative use within the preceding 24 hours. Participants missing with respect to the outcome measure were scored as non-responders. (NCT03120520)

Change From Baseline in the Weekly Rate of Complete Spontaneous Bowel Movements (CSBM)

The weekly Complete Spontaneous Bowel Movement (CSBM) totals are derived from the daily diary entries reported during the Treatment Period in the Bowel Movement (BM) and symptom diaries. Baseline is the mean number of CSBMs recorded during the 2-week baseline diary assessment period prior to the first dose of study drug. Spontaneous Bowel Movement (SBM) was defined as a bowel movement that occurs in the absence of laxative use within the preceding 24 hours. CSBM was defined as a spontaneous bowel movement with the sense of complete evacuation. (NCT03120520)
