Big pharma interest in earlier
Korea-based trials
South Korea’s foreign sponsor and CRO
attraction over the last decade has scope to increase if it can improve
capabilities in early phase and complex trials, experts said.
The region may also continue to attract
multinationals aiming to exploit a potentially more streamlined drug approval
process across Asia, they added.
Clinical trial registration in South Korea
shot up from 17 multinational-sponsored trials in 2002 to 296 in 2015,
according to figures from Korea’s Ministry of Food and Drug Safety (MFDS). The
US National Institutes of Health clinical trials database indicates 293 trials
registered in Korea so far in 2016 and ranks South Korea first in Asia by
number of protocols.
Korea National Enterprise for Clinical Trials
(KoNECT), an organization funded by the government since 2007 to improve the
quality of research sites - drove the increase in trials, agreed Greg Koski,
CEO of US-based Alliance for Clinical Research Excellence and Safety (ACRES)
and Fred Pritchard, VP, global drug development, at US CRO Celerion. Koski and
Pritchard said KoNECT’s funding of an accreditation program for sites and
training for clinical monitors over the last decade improved startup times,
completion rates, accuracy of data, and enrollment. According to KoNECT, while
the number of global clinical trial sites decreased 14% over 2010-2014, South
Korea grew 6.8%, ranking it 11th in 2014 globally for industry-sponsored
clinical sites. But the site standards are not very robust, said Koski, adding
ACRES and KoNECT are working together to improve site efficiency by creating
global site accreditation.
Site standards
and Phase I regulation has room for improvement
Koski and Pritchard added although Korea has
strongly attracted late-phase research, it lags in capabilities for early-phase
trials - still limited by red tape - and complex studies, such as those for
precision medicine. Pritchard said CROs Parexel (NASDAQ:PRXL), Covance, owned
by LabCorp (NYSE:LH), INC Research (NASDAQ:INCR), Quintiles (NYSE:Q) and PPD
have placed later stage clinical trials in South Korea, but now they and large
pharma, among them J&J (NYSE:JNJ), Merck (NYSE:MRK) and Sanofi (EPA:SAN),
are interested in moving earlier- phase trials into the country.
KoNECT President Deborah Chee said KoNECT and
umbrella initiative Korea Clinical Trials Global Initiative (KCGI) have been
working to improve early-phase and complex clinical trial capabilities by
establishing clinical pharmacology units - supporting Phase I research -- at 15
university hospitals by 2014. A separate investment was made in early
phase-focused personnel, equipment and training at five trial site clusters
across the country, and in translational research, said Chee and Min Soo Park,
KCGI Chair.
Additional hurdles to overcome in order for
Korea to retain foreign sponsor engagement include the need for greater global
visibility and a more transparent review process from MFDS, said Park. Chee
added KoNECT may work to allow a single institutional review board (IRB) review
for multi-site trials, instead of currently required separate submissions.
Pritchard noted medium-sized CROs like Celerion moving into South Korea should
be aware of different business requirements from the US - like needing to
establish a physical office in Korea before obtaining a formal business license
and hiring staff.
Chee
added KoNECT is also consulting with the industry to reduce trial review
bottlenecks, launching a campaign to improve patient awareness of trials, and
developing KoNECT Integrated Clinical Trial Information System (KIIS), a
database available to sponsors with epidemiology and investigator data. KoNECT
last year opened a support center for foreign sponsors, with a match-making
service with local partners, said Chee.
Gateway to earlier Asia approvals and launches
For multinationals wishing to secure earlier
market approvals in Asia and decrease the launch lag after EMA and FDA
approvals, conducting research in South Korea is the best gateway, said
Pritchard.
The common lag is partly due to Korean,
Japanese and Chinese regulators’ requirement that some research, often
pharmacokinetic, be performed in the countries’ own ethnic populations, said
experts. Typically, pharma companies leave Asian regulatory strategy until
Phase II or III when they realize they have neglected to include enough Asian
subjects, said Kenneth Kim, CEO of US CRO WCCT. “These companies are leaving
money on the table by neglecting a market for five years, and it can amount to
USD 100m or more per year in lost sales,” said Kim, whose company, like
Celerion, Parexel and a handful of other CROs, performs bridging trials in the
US with patients of Japanese ethnic origin in order to show safety and efficacy
in Asian populations. There has been a gradual and significant decrease in the
global need for bridging studies, Park confirmed, which he attributed to
multinationals moving more trials to South Korea, and so including Asian
subjects throughout the clinical program. Kim noted starting clinical programs
in Asian patients from the beginning is cheaper than performing a bridging
study, which costs around USD 1m.
As pharma moves away from viewing Asian
markets as an afterthought, many will decide Korea is the easiest Asian country
for US and European companies to run trials, said Pritchard, especially as
regulators in Japan, China and South Korea agreed to begin accepting Asian PK
data from each other’s’ populations. Since 2006, the Japanese regulator, PMDA,
has approved more than 20 compounds supported by Asian sub-group analysis data
obtained abroad, including in Korea, Chee confirmed.
Chee agreed Korea will prove the most
attractive region for sponsors seeking Asian trials, citing the shortest study
start-up time of all Asian countries. Trial review for study initiation takes
30 days in South Korea if there are no supplementary requirements, she said,
and on average takes four to eight weeks, with the IRB process running in
parallel. Pritchard claimed the Japanese regulator is perceived to lag in trial
approval time. The Chinese regulator, CFDA, can take up to 18 months for study
approval, as amendments to trial applications require restarting the review
process, according to research by PPD.
