and Abdominal Pain Score in Patients with Irritable Bowel Syndrome
with Constipation (IBS-C) Treated with
Tenapanor |

In addition to the poster presentation during DDW, Ardelyx is
sponsoring a Product Theater titled: Discover a Different Mechanism
of Action to Treat Adults with IBS-C: A Case Based Discussion, on
May 8, 2023, from 9:30-10:15am CT, where Darren Brenner, M.D.,
Professor of Medicine and Surgery, Northwestern University Feinberg
School of Medicine, will review the multifactorial pathophysiology
of IBS-C, the novel mechanism of action of IBSRELA, and efficacy
and safety data of IBSRELA from the Phase 3 clinical trial program.
Dr. Brenner will also review two patient cases and discuss
treatment decisions in IBS-C.
INDICATION IBSRELA (tenapanor) 50mg BID is
indicated for the treatment of Irritable Bowel Syndrome with
Constipation (IBS-C) in adults.
IMPORTANT SAFETY
INFORMATION
WARNING: RISK OF SERIOUS DEHYDRATION IN PEDIATRIC
PATIENTS
IBSRELA is contraindicated in patients less than 6 years
of age; in nonclinical studies in young juvenile rats
administration of tenapanor caused deaths presumed to be due to
dehydration. Avoid use of IBSRELA in patients 6 years to less than
12 years of age. The safety and effectiveness of IBSRELA have not
been established in patients less than 18 years of
age.
CONTRAINDICATIONS
- IBSRELA is contraindicated in patients less than 6 years of age
due to the risk of serious dehydration.
- IBSRELA is contraindicated in patients with known or suspected
mechanical gastrointestinal obstruction.
WARNINGS AND PRECAUTIONSRisk of Serious
Dehydration in Pediatric Patients
- IBSRELA is contraindicated in patients below 6 years of age.
The safety and effectiveness of IBSRELA in patients less than 18
years of age have not been established. In young juvenile rats
(less than 1 week old; approximate human age equivalent of less
than 2 years of age), decreased body weight and deaths occurred,
presumed to be due to dehydration, following oral administration of
tenapanor. There are no data available in older juvenile rats
(human age equivalent 2 years to less than 12 years).
- Avoid the use of IBSRELA in patients 6 years to less than 12
years of age. Although there are no data in older juvenile rats,
given the deaths in younger rats and the lack of clinical safety
and efficacy data in pediatric patients, avoid the use of IBSRELA
in patients 6 years to less than 12 years of age.
Diarrhea Diarrhea was the most common adverse
reaction in two randomized, double-blind, placebo-controlled trials
of IBS-C. Severe diarrhea was reported in 2.5% of IBSRELA-treated
patients. If severe diarrhea occurs, suspend dosing and rehydrate
patient.
MOST COMMON ADVERSE REACTIONS The most common
adverse reactions in IBSRELA-treated patients (incidence ≥2% and
greater than placebo) were: diarrhea (16% vs 4% placebo), abdominal
distension (3% vs <1%), flatulence (3% vs 1%) and dizziness (2%
vs <1%).

About Irritable Bowel Syndrome with Constipation
(IBS-C)Irritable bowel syndrome with constipation (IBS-C)
is a gastrointestinal disorder characterized by both abdominal pain
and altered bowel movements, estimated to affect 12 million people
in the US. IBS-C is associated with significantly impaired quality
of life, reduced productivity, and substantial economic burden.
About IBSRELA for IBS-C IBSRELA (tenapanor) is
a locally acting inhibitor of the sodium/hydrogen exchanger 3
(NHE3), an antiporter expressed on the apical surface of the small
intestine and colon primarily responsible for the absorption of
dietary sodium. By inhibiting NHE3 on the apical surface of the
enterocytes, tenapanor reduces absorption of sodium from the small
intestine and colon, thus retaining luminal water content, which
accelerates intestinal transit time and results in a softer stool
consistency. IBSRELA has also been shown to reduce abdominal pain
by decreasing visceral hypersensitivity and by decreasing
intestinal permeability in animal models. In a rat model of colonic
hypersensitivity, tenapanor reduced visceral hyperalgesia and
normalized colonic sensory neuronal excitability.
About Ardelyx, Inc.Ardelyx was founded with a
mission to discover, develop and commercialize innovative,
first-in-class medicines that meet significant unmet medical needs.
Ardelyx’s first approved product, IBSRELA® (tenapanor) is available
in the United States and Canada. Ardelyx is developing XPHOZAH®
(tenapanor), a novel product candidate for the control of serum
phosphorus in adult patients with chronic kidney disease (CKD) on
dialysis, which has completed three successful Phase 3 trials.
Ardelyx has a Phase 2 potassium lowering compound, RDX013, for the
potential treatment of elevated serum potassium, or hyperkalemia, a
problem among certain patients with kidney and/or heart disease and
an early-stage program in metabolic acidosis, a serious electrolyte
disorder in patients with CKD. Ardelyx has established agreements
with Kyowa Kirin in Japan, Fosun Pharma in China and Knight
Therapeutics in Canada for the development and commercialization of
tenapanor in their respective territories. For more information,
