China Medical System: An Innovative Drug, ILUMETRI 'Tildrakizumab Injection'
Approved for Marketing in China

SHENZHEN, CHINA, May 30, 2023 (GLOBE NEWSWIRE) --

  * CMS is pleased to announce the NDA of Tildrakizumab Injection under the
    brand name of ILUMETRI, a monoclonal antibody specifically targeting the
    p19 subunit of IL-23, has been approved in China. ILUMETRI is indicated
    for the treatment of adults with moderate-to-severe plaque psoriasis who
    are candidates for systemic therapy or phototherapy.
  * The extended study of ILUMETRI’s Phase III clinical trial in China,
    demonstrated that the primary efficacy assessment indicator PASI 75
    response rate continued to increase over treatment time. The PASI 75
    response rate reached a high level after 28 weeks of treatment with
    ILUMETRI and maintained at 91.3% at week 52, and ILUMETRI showed good
    long-term safety and tolerance.
  * ILUMETRI only needs to be administered 4 times a year during maintenance
    treatment period, which may bring higher patient compliance.
  * ILUMETRI will synergize with CMS Aesthetics’ marketed products, Hirudoid,
    Aethoxysklerol and pipeline products, to solidify comprehensive
    competitiveness of CMS in the dermatology field.
  * This is CMS’s second innovative drug approved for marketing in China this
    year following the approval of Methotrexate Injection.

On May 30, China  Medical  System Holdings  Limited  ("CMS" or  the  "Group")
announced that on 26 May 2023, the New Drug Application (NDA) of Tildrakizumab
Injection under the brand name of  ILUMETRI has been approved by the  National
Medical Products Administration of China (NMPA). ILUMETRI is indicated for the
treatment  of  adults  with   moderate-to-severe  plaque  psoriasis  who   are
candidates for systemic therapy or phototherapy.

ILUMETRI is a  humanized lgG1/κ  monoclonal antibody  designed to  selectively
bind to the p19 subunit of interleukin-23 (IL-23) and inhibit its  interaction
with  the  IL-23   receptor,  leading   to  inhibition  of   the  release   of
pro-inflammatory cytokines and chemokines. ILUMETRI has patents on composition
and formulation in China.

The results of the  extended study of  its Phase III  clinical trial in  China
demonstrated that the primary efficacy  assessment indicator PASI 75  response
rate continued to  increase over  treatment time.  The PASI  75 response  rate
reached a high level after 28 weeks of treatment with ILUMETRI and  maintained
at 91.3% at week 52, and ILUMETRI showed good long-term safety and  tolerance.
ILUMETRI only  needs to  be administered  4 times  a year  during  maintenance
treatment period, which may bring higher patient compliance.

Psoriasis is  an  autoimmune  disease  with complex  causes,  where  IL-23  is
regarded as  one of  the  important driving  factors  of the  pathogenesis  of
psoriasis. The incidence of psoriasis in China is about 0.47%, with the number
of patients exceeding 7  million, of which more  than 30% have developed  into
moderate-to-severe disease.  ILUMETRI will  provide moderate-to-severe  plaque
psoriasis patients with a safe and effective treatment option.

It took only 14 months from obtaining the approval for the drug clinical trial
to submitting  the NDA  for ILUMETRI  in  China, with  the enrollment  of  220
subjects completed in only  2.5 months (which  included the Spring  Festival),
highlighting  CMS’s   highly  efficient   clinical  development   capabilities
supported by its commercialization strength.

ILUMETRI is CMS’s second innovative drug  approved to be marketed in China  in
2023, following  the  recent  approval  of  Methotrexate  Injection.  CMS  has
invested in, and  collaborated with,  innovative companies  globally over  the
last 5 years to  jointly develop innovative products  with academic value  and
differentiated advantages, in order to  meet unmet clinical needs and  enhance
the accessibility of  global innovative drugs  for Chinese patients.  Starting
from 2023, CMS’s innovation development is stepping into the harvest period.

ILUMETRI  has  been  approved   for  marketing  in   the  Hong  Kong   Special
Administrative Region of China in April 2022. Tildrakizumab Injection has also
been approved for marketing in the  U.S., EU, Japan, UK, Switzerland,  Canada,
Australia and other countries/regions.
