NEW YORK--(EON: Enhanced Online News)--Synergy Pharmaceuticals Inc. (NASDAQ:SGYP) today announced that the United States Patent and Trademark Office (USPTO) has issued three new patents covering TRULANCE (plecanatide). The first patent relates to the method for manufacturing TRULANCE and will expire March 1, 2032. The two other patents relate to formulations and methods of using TRULANCE for treating chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C) at 3mg or 6 mg dose; both of these patents will expire September 15, 2031.
“We are very pleased these additional patents were allowed and issued as they are a significant addition to the TRULANCE patent portfolio, providing extended exclusivity protection for TRULANCE”
“We are very pleased these additional patents were allowed and issued as they are a significant addition to the TRULANCE patent portfolio, providing extended exclusivity protection for TRULANCE”, said Dr. Gary S. Jacob, Chairman and Chief Executive Officer of Synergy Pharmaceuticals Inc. “This marks an important step in our ongoing efforts to optimize the value of TRULANCE.”
TRULANCE is a once-daily tablet approved by the Food and Drug Administration (FDA) for the treatment of adults with CIC and is currently being evaluated for the treatment of adults with IBS-C. The company began marketing TRULANCE in the U.S. for adults with CIC on March 20, 2017. The recommended dosage of TRULANCE is 3 mg taken orally, once daily, with or without food at any time of the day.
On March 24, 2017, the company submitted a supplemental New Drug Application (sNDA) for TRULANCE for the treatment of adults with IBS-C.
Indications and Usage
TRULANCE is a guanylate cyclase-C (GC-C) agonist indicated in adults for the treatment of chronic idiopathic constipation (CIC).
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 two placebo-controlled clinical trials. Severe diarrhea was reported in 0.6% of 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% than in the placebo group) was diarrhea (5% vs 1% placebo).

TRULANCE™ (plecanatide) is a once-daily tablet approved for adults with CIC and is being evaluated for 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.
