CFDA Reform announced
By 3 years
: Reduce application
backlog and encourage
innovation
Recent news from CFDA (generally seen as positive):
•Speed up regulatory reviews for drugs with high clinical demand
•Improve quality of review & approval process
•Resolve registration application backlog
•Encourage new drug research & invention
•Increase review and evaluation transparency
Opportunities of CFDA Reforms
• Shortened CTA/NDA review timeline; priority review channel
• Sample size requirement negotiable for rare disease
• Potential removal of 2nd submission
• Imported Cat 1 path
• CMO-local manufacture capability
• CMC change during development
China Guideline
on Multiregional Clinical Trials
(MRCT)
Why Multiregional Clinical Trials (MRCT)?
Purpose and Scope of MRCT
• China Food and Drug Administration (CFDA) issued the new
Guidance for International Multicenter Clinical Trials (IMCT)
in January 30, 2015
• This Guidance is to guide the application, implementation and
management of the IMCT in China.
• Sponsor are encouraged to conduct IMCT in China in the areas
with unmet medical needs, to evaluate the feasibility in the early
stage of conducting global pivotal studies and regional studies
in China, and to consider conducting pivotal studies in China as
well as regional clinical trials targeted for Chinese patient
populations.
China Guideline on MRCT
• To encourage to conduct MRCT in China in the areas with unmet
medical needs
• MRCT study requires at least two countries including China.
• MRCT for registration purpose:
– Besides MRCT dataset, trending analysis of Asian vs
Non-Asian subjects and Chinese subjects vs other countries
are required. Detailed requirements will be published in the
future.
– MRCT study needs to meet statistic requirement and the
trending analysis of local subgroup should be consistent with
the entire MRCT population.
– According to guidance, local sample size should be big
enough to evaluate safety and efficacy in China and meet the
requirement of statistical and local regulation

CFDA MRCT Guidance Key Points
Chapter 1: Background
• Global development could reduce duplicated clinical trial and
shorten drug lag.
• Type of global study
–
Global pivotal study
–
For scientific and safety considerations, the sponsor may conduct the
regional clinical trials
• Drug registration in China supported by MRCT data should
fulfill Drug Registration Regulation.
Chapter 2: Purpose and Scope
• Sponsor are encouraged to conduct MRCT in China in the areas
with unmet medical needs, global pivotal studies and regional cli
nical trials targeted for Chinese patient populations.
• Improve local development capacity, intellect and globalization.
CFDA MRCT Guidance Key Points Cont.
Chapter 3: General Requirements
•
At least two countries including China: China plus 1
•
No need ICH country for China+ and CFDA does not comment HK or
TW as China+.
•
Early evaluation for development strategy, such as disease epidemiolo
gy and medical practices.
•
MRCT for registration purpose:
– Besides global CSR, analysis for AP and China population is requir
ed, especially for China’s medical practice, i.e. whether the study p
opulation is representative
– Local sample size: big enough to evaluate safety and efficacy in
China and meet the requirement of statistical and local regulation
– Oversea inspection for all MRCT sites (risk and route cause drive
n spot-check).
CFDA MRCT Guidance Key Points Cont.
Chapter 4: Considerations on Trial Scientific
•
Disease epidemiology: focus on Incidence/prevalence, Etiology and risk factors and Prognosis
•
Differences in medical practice: local guideline and local experts
•
Differences in drug metabolism: internal and external factors which may cause differences
•
Dose selection: the rational of dose selection
•
Selection of control drug: conduct full argumentation based on approved indications, availabili
ty and usage
•
Efficacy evaluation: independent and unified evaluation of the primary efficacy indicators an
d central laboratories.
•
Sample size considerations: the minimal sample size need to meet regulation requirement an
d the Chinese proportion need to be considered as well. CFDA will be more prudent for samp
le size reduction.
•
Statistical considerations: the whole study need to meet statistic requirement and the trendin
g analysis of local data should be consistent with the results of entire MRCT.
•
Collection and evaluation of adverse events/reactions: ICH guidance
•
IDMC and EAC: Suggest to have Chinese experts sit in IDMC and EAC if Chinese subjects is
more than 20% of total subjects (Not mandatary)
CFDA MRCT Guidance Key Points Cont.
Chapter 5: Considerations on Trial Standardization
• Sponsor should register the drug clinical trial and disclose related information
on the clinical trial information platform of the CFDA
(website: http://www.chinadr
ugtrials.org.cn/). The information required to be
registered includes domestic and overseas principal investigators and clinical
trial institutions.
• IRB approval could be in parallel with CTA review in after the effective of new
GCP guidance (still seeking comments).
• Need to evaluate the possibility to shipping out the bio samples
Chapter 6: Clinical Trial Protocol Amendment
• Protocol amendment need to submit supplementary application before
implementation. The pathway is not very clear based on the current regulation..
–
Big impact to subjects safety
–
Significant change to ratio of risk/benefit
–
Large increase of Chinese subjects
Notes: We checked with CFDA in Mar 02 2015, CFDA reception center still not
accepted this kind of application at this moment
CFDA MRCT Guidance Key Points Cont.
Chapter 7: Registration Application
• Global clinical trial report, statistical analysis reports, databases of MRCT need to submitted
and subgroup analysis.
• Dossier should follow ICH CTD Format
• Additional documents required are as below:
– An evaluation of the entire MRCT dataset.
– Trending analysis of Asia and Non-Asia subjects.
– Trending analysis of Chinese subjects and other countries subjects.
• Notification and clarification is required for the early terminated or failure MRCT
Chapter 8: On-Site Inspection
• CFDA will strengthen clinical trial inspection basing risk and review requirement
• Besides site, the inspection will also focus on sponsor, documentation ie GDP and CRO.
Chapter 9: Glossary
• Pivotal Study, IDMC, EAC, ICH-CTD
Opportunity and Considerations
on MRCT
Opportunity and Considerations on MRCT
• ICH E17 is under discussion
• MRCT basic principles:
– Acceptability
• Design & implementation of MRCT need to satisfy the requirement of
EC/ ICH GCP, to ensure the quality and reliability of the clinical trial
– Applicability
• MRCT data can be applicable to similar patients in the country/region,
HA can make the NDA approval basing these data.
• MRCT main challenge: Scientific and rigorous Statistical
analysis of MRCT data
– Overall result of MRCT
– Results in all relevant areas and samples configuration
– Results “consistence” in different regions
The Future Opportunities of MRCT
Case Studies
Potential Ethnic Differences in Asian vs. Western
Populations must be Carefully Evaluated in Pivotal Trials
