NEW YORK--(BUSINESS WIRE)--Synergy Pharmaceuticals Inc. (NASDAQ: SGYP), a biopharmaceutical company focused on the development and commercialization of novel gastrointestinal (GI) therapies, today announced three abstracts that will be presented at Digestive Disease Week (DDW) in Washington D.C. June 2-5, 2018.
The presentations include a late-breaking clinical science abstract revealing novel findings from the first study to evaluate uroguanylin response levels in healthy subjects compared to patients with chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C). Uroguanylin is a naturally occurring and endogenous human GI peptide that stimulates fluid secretion within the small intestine.
Additional poster presentations will highlight a new retrospective risk/benefit analysis of TRULANCE® (plecanatide) and linaclotide for the treatment of adults with CIC, as well as long-term safety and effectiveness data for TRULANCE in IBS-C patients.
The data will be presented via poster presentations as follows:
Safety, Tolerability, and Effectiveness of Plecanatide in Patients with Constipation-Predominant Irritable Bowel Syndrome: Long-Term Evidence from an Open-Label Study (6050), to be presented on Sunday, June 3, 2018 from 12:00 p.m. – 2:00 p.m. ET, by Charles F. Barish, M.D., Wake Gastroenterology.
Postprandial Pro-Uroguanylin Endocrine Responses Are Attenuated in Patients with CIC and IBS-C (8335), to be presented on Tuesday, June 5, 2018, 12:00 p.m. – 2:00 p.m. ET, by Scott A. Waldman, M.D., PhD, Professor Chair, Pharmacology & Experimental Therapeutics, Sidney Kimmel Medical College, Thomas Jefferson University.
Evaluation of Therapeutic Risk/Benefit Ratios from Pooled Plecanatide and Linaclotide Phase 3 Trials in Adult Patients with Chronic Idiopathic Constipation (8000), to be presented on Tuesday, June 5, 2018, 12:00 p.m. – 2:00 p.m. ET, by Darren M. Brenner, M.D., Associate Professor of Medicine (Gastroenterology and Hepatology) and Surgery, Northwestern Feinberg School of Medicine.
Indications and Usage
TRULANCE (plecanatide) 3 mg tablets is indicated in adults for the treatment of Chronic Idiopathic Constipation (CIC) and Irritable Bowel Syndrome with Constipation (IBS-C).
IMPORTANT SAFETY INFORMATION
WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS
TRULANCE® is contraindicated in patients less than 6 years of age; in nonclinical studies in young juvenile mice administration of a single oral dose of plecanatide caused deaths due to dehydration. Use of TRULANCE should be avoided in patients 6 years to less than 18 years of age. The safety and efficacy of TRULANCE have not been established in pediatric patients less than 18 years of age.
- TRULANCE is contraindicated in patients less than 6 years of age due to the risk of serious dehydration.
- TRULANCE is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction.
Warnings and Precautions
Risk of Serious Dehydration in Pediatric Patients
- TRULANCE is contraindicated in patients less than 6 years of age. The safety and effectiveness of TRULANCE in patients less than 18 years of age have not been established. In young juvenile mice (human age equivalent of approximately 1 month to less than 2 years), plecanatide increased fluid secretion as a consequence of stimulation of guanylate cyclase-C (GC-C), resulting in mortality in some mice within the first 24 hours, apparently due to dehydration. Due to increased intestinal expression of GC-C, patients less than 6 years of age may be more likely than older patients to develop severe diarrhea and its potentially serious consequences.
- Use of TRULANCE should be avoided in patients 6 years to less than 18 years of age. Although there were no deaths in older juvenile mice, given the deaths in young mice and the lack of clinical safety and efficacy data in pediatric patients, use of TRULANCE should be avoided in patients 6 years to less than 18 years of age.
- Diarrhea was the most common adverse reaction in the four placebo-controlled clinical trials for CIC and IBS-C. Severe diarrhea was reported in 0.6% of TRULANCE-treated CIC patients, and in 1% of TRULANCE-treated IBS-C patients.
- If severe diarrhea occurs, the health care provider should suspend dosing and rehydrate the patient.
- In the two combined CIC clinical trials, the most common adverse reaction in TRULANCE-treated patients (incidence ≥2% and greater than in the placebo group) was diarrhea (5% vs 1% placebo).
- In the two combined IBS-C clinical trials, the most common adverse reaction in TRULANCE-treated patients (incidence ≥2% and greater than in the placebo group) was diarrhea (4.3% vs 1% placebo).
About Chronic Idiopathic Constipation (CIC)
CIC affects approximately 14 percent of the global population, disproportionately affecting women and older adults. People with CIC have persistent symptoms of difficult-to-pass and infrequent bowel movements. In addition to physical symptoms including abdominal bloating and discomfort, CIC can adversely affect an individual’s quality of life, including increasing stress levels and anxiety.
About Irritable Bowel Syndrome with Constipation (IBS-C)
Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by recurrent abdominal pain and associated with two or more of the following: related to defecation, associated with a change in the frequency of stool, or associated with a change in the form (appearance) of the stool. IBS can be subtyped by the predominant stool form: constipation (IBS-C), diarrhea (IBS-D) or mixed (IBS-M). Those within the IBS-C subtype experience hard or lumpy stools more than 25 percent of the time they defecate, and loose or watery stools less than 25 percent of the time. It is estimated that the prevalence of IBS-C in the U.S. adult population is approximately 4 to 5 percent.
TRULANCE® (plecanatide) is a once-daily tablet approved for adults with CIC or IBS-C. With the exception of a single amino acid substitution for greater binding affinity, TRULANCE is structurally identical to uroguanylin, a naturally occurring and endogenous human GI peptide. Uroguanylin activates GC-C receptors in a pH-sensitive manner primarily in the small intestine, stimulating fluid secretion and maintaining stool consistency necessary for regular bowel function.
