drugs. IBD, which includes Crohn's disease and ulcerative colitis, has seen a
noticeable increase in cases across Japan. This surge can be attributed to a
complex interplay of genetic, environmental, and lifestyle factors that
contribute to the development and progression of the disease. In May 2022,
EA Pharma Co., Ltd. and Kissei
Pharmaceutical Co., Ltd. announced the launch of CAROGRA® Tablets
(nonproprietary name: carotegrast methyl; “CAROGRA”) for the treatment of
ulcerative colitis in Japan. The drug was added to the National Health
Insurance Drug Price List on May 25. CAROGRA is a novel small molecule
developed by EA Pharma (formerly Ajinomoto Pharmaceuticals Co., Ltd.), and is
the world's first α4 integrin antagonist available in an oral dosage form. It
targets both α4β1 and α4β7 integrins on inflammatory cells, providing
anti-inflammatory effects by reducing the excessive aggregation and
infiltration of these cells into the inflamed colonic mucosa in ulcerative
colitis.
Genetic predisposition plays a significant role in
the increasing prevalence of IBD. Research has identified various genetic
markers associated with an elevated risk of developing IBD. As our
understanding of these genetic factors grows, it becomes evident that a
significant portion of the Japanese population may be genetically predisposed
to IBD, contributing to the rising incidence. The interplay between these
genetic factors and environmental triggers further exacerbates the situation,
leading to a higher number of diagnosed cases.
Environmental factors, such as changes in diet,
pollution, and lifestyle, also contribute to the growing prevalence of IBD. In
Japan, dietary changes and urbanization have led to lifestyle shifts that are
believed to impact gut health. For instance, increased consumption of processed
foods and changes in traditional eating habits may influence gut microbiota,
potentially contributing to the development of IBD. Environmental pollutants
and exposure to various chemicals can affect gut inflammation and immune
responses, further driving the incidence of IBD. Lifestyle changes, including
stress and sedentary behavior, have been linked to a higher risk of developing
IBD. In modern Japan, increasing stress levels and changes in physical activity
patterns are believed to impact gastrointestinal health. Stress has been shown
to affect gut permeability and immune function, potentially contributing to the
onset and progression of IBD. As lifestyle factors evolve, their impact on IBD
prevalence becomes more pronounced, necessitating effective treatment options.

Segmental Insights
Disease Type Insights
Based on the Disease Type, ulcerative
colitis (UC) currently dominates over Crohn’s disease. This dominance is driven
by several factors related to the epidemiology, clinical management, and
treatment needs specific to UC.
Ulcerative colitis,
characterized by inflammation confined to the colon and rectum, is more
prevalent in Japan compared to Crohn’s disease, which can affect any part of
the gastrointestinal tract. The higher prevalence of UC in Japan is reflected
in the greater demand for drugs targeting this condition. Epidemiological data
indicates that UC cases outnumber those of Crohn’s disease, making it a focal
point for pharmaceutical companies and healthcare providers. This prevalence
drives the market for UC-specific therapies, which are tailored to manage the
unique challenges of this condition. The clinical management of ulcerative
colitis in Japan requires a range of drug therapies, from anti-inflammatory
agents to biologics and immunosuppressants. UC’s treatment landscape includes
established drugs such as 5-aminosalicylic acids (5-ASAs), corticosteroids, and
immunomodulators, as well as newer biologic therapies. The need for ongoing
management and new therapeutic options for UC patients contributes to its
dominance in the market. Given the chronic nature of UC, patients often require
long-term medication regimens, which drives consistent demand for these drugs.
Drug Class Insights
Based on Drug Class, TNF
inhibitors currently dominate over JAK inhibitors, aminosalicylates, and
corticosteroids. This dominance is driven by their efficacy, advanced
therapeutic profiles, and the growing need for targeted treatments for IBD. TNF
inhibitors, such as infliximab and adalimumab, have become the cornerstone of
treatment for both Crohn’s disease and ulcerative colitis. These biologic
agents target tumor necrosis factor-alpha (TNF-α), a cytokine that plays a
central role in the inflammatory process of IBD. The effectiveness of TNF
inhibitors in reducing inflammation, promoting mucosal healing, and improving
patient outcomes has made them a preferred choice in the management of IBD.
Their ability to induce and maintain remission in patients with moderate to
severe forms of IBD contributes to their dominant position in the market.
The success of TNF
inhibitors is reflected in their widespread use and the significant market
share they command. These drugs are often prescribed when conventional
treatments, such as aminosalicylates and corticosteroids, are insufficient. TNF
inhibitors provide an advanced therapeutic option for patients who have not
responded adequately to first-line treatments, making them a critical component
of the IBD drug landscape in Japan.
In comparison, JAK
inhibitors, which include medications like tofacitinib, are emerging treatments
that offer a novel approach to managing IBD. JAK inhibitors work by interfering
with the Janus kinase (JAK) signaling pathways involved in inflammation.
Although these drugs show promise and have been gaining traction, they are
still relatively new to the market compared to established TNF inhibitors.
Their adoption is increasing, but they have not yet reached the same level of
dominance as TNF inhibitors. Aminosalicylates, such as mesalamine, are another
class of drugs used primarily in the treatment of mild to moderate ulcerative
colitis. While they are effective for managing inflammation and maintaining
remission, their role is somewhat limited compared to the more potent TNF
inhibitors. Aminosalicylates are often used as a first-line treatment, but they
do not offer the same level of efficacy in severe cases of IBD as TNF
inhibitors do.
