(plecanatide) will be shared at the American Association of Nurse Practitioners' (AANP) 2021 AANP National Conference, which takes place virtually June 15 through Aug. 31, 2021.

The following posters will be available on the AANP online platform:

• Brenner, Darren et al. "Plecanatide provides meaningful improvement in patients with chronic idiopathic constipation and irritable bowel syndrome with constipation reporting reduced quality of life: analyses from four randomized phase 3 trials."

• Martinez de Andino, Nicole et al. "Early response to plecanatide predicts overall treatment response in patients with chronic idiopathic constipation."

About TRULANCE

Indication

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).

Contraindications

• 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

• 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.

Adverse Reactions

• 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).
