Unprecedented 3-Year Safety Data Unveiled at Digestive Disease Week (DDW) Indicates No Pattern of Heartburn with IBgard®, an Advanced Technology Peppermint Oil, Contrary to Heartburn Issues with Older Technologies

Data from a 36-month, real-world, post-marketing study confirms the safety profile of IBgard® (PO-SST), a novel peppermint oil product in patented solid-state microspheres, is now available for review on the DDW e-poster website.

  • In one of the longest-running post-marketing surveillance
    studies of its kind, involving an estimated 2.4 million users, data showed that
    IBgard is a safe and well-tolerated option for managing IBS.
  • No pattern of heartburn was seen with IBgard. As
    noted in the 2018 American College of Gastroenterology (ACG), IBS Monograph
    1, among older, liquid-filled,
    “burst technology” peppermint oil products, heartburn is a common side effect. The
    2018 ACG IBS Monograph called for a more distal delivery of peppermint oil.
  • IBgard, with its novel,  triple-coated microsphere technology,
    provides more distal delivery by avoiding release in the stomach, by targeting
    the small intestine, and by then releasing over 4 hours.
    It thus avoids the problems of older PO products, particularly heartburn.

BOCA RATON, Fla. – (May 5, 2020) – IM HealthScience® (IMH) today announced that the Irritable Bowel Syndrome Safety Update
at 36 months (IBSSU36) study is now available for
review as an e-poster on the Digestive Disease Week® (DDW) e-poster
 and e-paper web site;

The peer-reviewed and published e-poster

IBSSU36 is a real-world safety surveillance study reporting on the safety
and tolerability profile of IBgard® and was conducted to determine
if any issues, including heartburn or anal burning, were surfacing as a side
effect. In the American College of Gastroenterology 2018 IBS Monograph,
heartburn was noted as a side effect of conventional peppermint oil
preparations.1 In the same 2018 Monograph, it was noted that
heartburn is an issue because the IBS population has four times the heartburn
as the general population.3
The authors of the study poster note that older, liquid-filled, burst
technology peppermint oil products showed that as high as 26 to 29.7% of
patients experience adverse events (AEs), heartburn being the most common.4,5
A key finding of this study is that no pattern of heartburn or anal
burning was observed during the 36-month timeframe with IBgard.  

Commenting on the findings of the study,
Brian Lacy, M.D., PhD, FACG, a leading gastroenterologist at the Mayo Clinic
and the lead author of the study, said, “We know that peppermint oil improves
the symptoms of IBS, but many older peppermint oil products can cause unwanted
side effects, such as heartburn. IBgard, with its targeted delivery to the
small intestine, was shown in this study to avoid any pattern of heartburn or
anal burning, even after 36 months and an estimated 2.4 million patients had
taken the product.”

The 3-year data safety analysis also confirmed
that no reports of serious adverse events  and no significant pattern of non-serious
adverse events had emerged. It is estimated that over 2.4 million individual
patients used the product during the three-year surveillance period of October
5, 2015, to September 30, 2018.

“We are gratified that this important
post-marketing study has been peer-reviewed and then published via a poster on
the DDW website,” said Michael Epstein, M.D., FACG, AGAF, a leading
gastroenterologist and Chief Medical Advisor for IM HealthScience. “It is
important for health care professionals and patients to be aware of the
excellent safety and tolerability profile of IBgard.”  

About IBSSU36   

Irritable Bowel Syndrome Safety Update at 36 Months (IBSSU36) is a
real-world surveillance study reporting on the safety and tolerability profile
of IBgard among an estimated 2.4 million individual patients who used the
product. An independent call center with pharmacovigilance-trained health care
personnel in accordance with U.S. Food and Drug Administration (FDA) and global
regulatory guidelines on properly reporting events was retained to receive and
record IBgard customer questions, product issues, and adverse events. The
adverse events for this study were collected and processed from October 5,
2015, to September 30, 2018. An analysis of the data by reviewers showed that
there were no reported serious adverse events associated with the use of IBgard
during this time frame.

About IBgard®

IBgard® is
a medical food specially formulated for the dietary management of IBS.
IBgard capsules contain solid-state microspheres of peppermint oil, including
its principal component l-Menthol, plus fiber and amino acids (from gelatin
protein), in a unique delivery system.

With its patented Site-Specific Targeting
(SST®) technology pioneered by IM HealthScience,
IBgard capsules release Ultramen®, an ultra-purified peppermint
oil, quickly and reliably to the small intestine, where it is designed to
release over 4 hours in a sustained release manner.2 The
food nutrients in IBgard (peppermint oil along with fiber and amino acids) may
help reduce the low-grade, localized, often temporary, reversible inflammation
found in some IBS patients and help normalize gut mucosal barrier function.
Additionally, peppermint oil has been shown to help normalize intestinal
transit time.6

IBgard previously was studied in a
pivotal, randomized, placebo-controlled, double-blinded, multi-center trial
called IBSREST†† (Irritable Bowel
Syndrome Reduction Evaluation and Safety
Trial).  Patients suffering from IBS-D and IBS-M
(alternating IBS-C and IBS-D) were included in the study. This important study
was presented at DDW in May 2015 to a standing-room-only audience. The study
findings were accepted after peer review and then published in the February
2016 issue of Digestive Diseases and Sciences, a leading,
peer-reviewed scientific journal.2, ††The
data showed that IBgard demonstrated a statistically significant reduction
in the Total IBS Symptom Score (TISS) in as early as 24 hours and at four
weeks. The TISS represents a composite score of eight individual IBS symptoms.In
a secondary analysis, IBgard also showed efficacy among IBS-M patients.8 IBS-M
has been observed to represent up to 74% of IBS patients.9,†

Additionally, results from a real-world
observational study of 285 patients who took IBgard, called IBSACT§
(Irritable Bowel Syndrome Adherence
and Compliance Trial), showed that there was a high
level of patient satisfaction with the product even among those patients taking
several capsules on a daily basis. One out of two IBS patients taking IBgard
needed only 1 to 2 capsules per day to obtain individualized relief from IBS
symptoms. In addition, 75 percent of the patients felt relief of abdominal
pain, discomfort and/or bloating within 2 hours, while 95 percent of patients
reported relief within 24 hours after taking IBgard.10,†

Currently, there are limited options for
patients with IBS that offer effective and rapid relief, especially during
flare-ups. Also, no Rx drug has been approved for IBS-M.

Over 10,000 healthcare practitioners,
including 3,000 gastroenterologists, are estimated to have already used IBgard
for their patients. For five consecutive years, IBgard continues to be the #1
recommended peppermint oil for IBSamong gastroenterologists
nationwide by an overwhelming margin.11

Like all medical foods, IBgard does not
require a prescription, but it must be used under medical supervision. Only a
physician can confirm suspected IBS. Many physicians are now recommending
taking IBgard 30-90 minutes before a meal, as it enables the supportive effect
of IBgard to start as early as possible.

IBgard is available to patients in
the digestive aisle at most Walmart, Target, CVS/pharmacy, Walgreens, and Rite
Aid stores nationwide as well as in grocery stores across the country and on
