Item 7.01
|
Regulation FD Disclosure.
|
Attached hereto as Exhibit 99.1 is a corporate presentation of Ardelyx, Inc.
(the “
Company
”) incorporated by reference herein.
The information furnished under this Item 7.01 shall not be considered
“filed” under the Securities Exchange Act of 1934, as amended, nor shall it be incorporated into any future filing under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, unless the Company
expressly sets forth in such future filing that such information is to be considered “filed” or incorporated by reference therein.
On October 11, 2017, the Company announced positive results from
T3MPO-2,
its second Phase 3 study of tenapanor for irritable bowel syndrome with constipation (“
IBS-C
”). The study hit statistical significance for the
primary endpoint and all secondary endpoints evaluated for the topline results and demonstrated the ability to normalize bowel movements. The primary endpoint, the combined responder rate for six of 12 weeks, showed that a greater proportion of
tenapanor-treated patients compared to placebo-treated patients (36.5% vs. 23.7%, p<0.001) had at least a 30 percent reduction in abdominal pain and an increase of one or more complete spontaneous bowel movements (“
CSBM
”) in
the same week for at least six of the 12 weeks of the treatment period. In addition, tenapanor achieved statistical significance for the CSBM and abdominal pain responder rates in the six of 12 and nine of
12-treatment
weeks, with a consistent response across the 26 weeks of the study. Tenapanor was well-tolerated in treated patients.
T3MPO-2
is a
26-week,
double-blind, placebo-controlled, multi-center,
randomized trial. The trial was conducted in a total of 593 patients meeting the ROME III criteria for the diagnosis of
IBS-C.
Patients were randomized
one-to-one
to receive either 50 mg of tenapanor (n=293) or placebo (n=300) twice-daily. The trial included a
two-week
screening period, during which patients with
active disease, based on bowel movement frequency and abdominal pain score recorded in a daily phone diary, were randomized into the trial.
During the
two-week
screening period, the baseline scores were well-balanced between the tenapanor and placebo groups. The mean weekly CSBMs were 0.11 and the mean abdominal pain score was 6.26 (on a 0 - 10 scale where 0 was
no pain and 10 was very severe).
Key data are as follows:

Tenapanor was well-tolerated, consistent with the experience across previous clinical trials. The only adverse events observed
in greater than two percent of patients in the tenapanor-treated group that were also greater than placebo were diarrhea (16.0% vs. 3.7%), flatulence (3.1% vs. 1.0%), nasopharyngitis (4.4% vs. 3.7%) and abdominal distension (3.4% vs. 0.3%). The
placebo adjusted discontinuation rate due to diarrhea was 5.8 percent.
Based on positive results from two, positive Phase 3 trials, the Company is
on track to submit a New Drug Application (“
NDA
”) to the U.S. Food and Drug Administration for tenapanor for the treatment of
IBS-C
in the second half of 2018. Final, detailed results from the
study are expected to be presented at a medical meeting in 2018.
Patients who have completed
T3MPO-1
and
T3MPO-2
are eligible to enter
T3MPO-3,
the Company’s open-label, long-term safety trial where patients can continue to receive tenapanor for up to one year.
T3MPO-3
is expected to conclude in late 2017 and the results of the trial will be included in the NDA submission for tenapanor for the treatment of patients with
IBS-C.
