The pharmaceutical industry is undergoing a significant change right
from drug development, tightening of regulations, to restructuring, all
in the midst of the economic downturn. The drop in the R&D spending
in the last few financial quarters has not only taken a toll on the
contract research organization (CRO) industry but also provided a
unique opportunity.
The increasing costs and falling productivity, are driving
pharmaceutical companies to outsource an increasing range of functions
to CROs, in search of time and cost savings. This produced strong
double-digit growth in the sector between 2003 and 2008. The global CRO
market was estimated at

($14 billion) in 2006 and it grew at an annual rate of 14-16
percent, to reach

Contract research is a relatively nascent service industry in India.
Like all other service industries in its infancy, CRO industry also
faces unique challenges, which when addressed, provides huge
opportunities. In 1990s, India saw the development of contract
research. The Indian Patents (Amendment) Act of 2005 triggered the
Indian pharmaceutical industry to invest in innovation, that led to the
development of a local market for research personnel. The process of
harmonization of research regulations led by the international
conference on harmonization (ICH) since 1990, also provided an impetus
for increase in the growth of research activities in the country.
Contract research has been a product of this growth in research
activities, that has led to the establishment of small and large drug
development service companies in preclinical and clinical domains.
Genesis of preclinical CROs
Over a decade ago, global CROs were seen as service providers for
pharmaceutical companies who generated routine data at the request of
client companies, and did not contribute to the overall strategy of
their drug development. This process underwent a critical change in the
1990s, when large global CROs were set up, and started attracting
highly-qualified scientists. These, in-turn, led to the development of
the CROs as center for scientific excellence in drug
development.
The inflection point was when these CROs instead of conducting work for
their clients, were also able to guide them through the entire drug
development process. With this, the dynamics of interaction between
CROs and pharmaceuticals changed in the recent times, from service
providers to working partners. The CROs with good scientific profiles
had gained massive experience and were able to capture the majority of
the preclinical market.
Indian CROs currently find themselves in the same position as the
global CROs were, about a decade ago. All trends suggest that the
Indian CROs are in the phase of significant upward movement. As of
today, partnerships with overseas companies have progressed beyond
synthesis and solid dosage formulations. What began as
project-by-project outsourcing, is giving way to long-term relations.
It is widely believed that Indian CROs will build a strong presence as
the economic recession ends, since global companies will rethink
aggressively towards cost-effective operations in R&D. Also, a
substantial growth in the preclinical outsourcing market is predicted
from 2011 onwards, due to the implementation of Registration,
Evaluation, Authorization and Restriction of Chemicals (REACH)
legislation and ever tightening controls on chemical, fertilizers,
cosmetics and food safety.
Further, the expectation that organization for economic cooperation and
development (OECD) will soon approve the Indian GLP program, should
provide the necessary impetus to preclinical services from India. These
factors are expected to be the key drivers of the preclinical market
for Indian CROs.
Preclinical outsourcing in chemistry.
The outsourcing of chemistry to India began in 1998, and has matured
today with many of the large pharmaceutical companies working with CROs
on an exclusive basis. The business models followed have included
setting up of joint facilities and venture companies. The outsourced
chemistry is expected to exceed
![](http://www.biospectrumindia.com/images/content/2010/aug/INR-currency_symbol.jpg)
19,678
crore
($4.2 billion) in fiscal 2009-10. The business is ready for the
next stage, where larger revenues could come from more value-added
services such as lead generation and hit-to-lead selection.
Preclinical outsourcing in biology
Preclinical outsourcing in biology is certainly at an exciting point
where serious deliberations and focused actions will determine where
the business will reach in the next few years. Until now the growth in
biology has been relatively slower than in chemistry, as there has been
a general perception that India is not competitive in the biology
space. Some of these factors have come in the way of capturing
significant foothold in the
![](http://www.biospectrumindia.com/images/content/2010/aug/INR-currency_symbol.jpg)
23,430
crore
($5 billion) worth biological contract research market (Kalorama
Information).
There has been a consistent effort from Indian biology-focused CROs in
the last couple of years to change this perception and capture the
untapped business. Indian CROs, in the last five to eight years, have
made significant investments in infrastructure, technology and talent
to attract business. The biology-focused CROs have expanded their
services to include recombinant DNA/protein-based activities, focused
screening of small molecules, and absorption, distribution, metabolism,
excretion, and toxicity (ADMET) profiling of lead compounds.
Indian CROs are now gearing up for the challenge to establish
themselves as providers of in vitro and in vivo preclinical development
services. Preclinical services are being considered as the fastest
growing outsourced segment of the drug development process. Estimates
suggest that there is a gap of approximately 20-30 percent between
demand and preclinical capacity globally, more so, in niche areas of
genetic toxicology and in vitro alternatives. Preclinical biology
outsourcing can be defined and distinguished at two different realms:
traditional toxicology profiling and discovery research. Indian CROs
have a successful history of providing toxicology support, and this is
not expected to diminish in the near future. The second component –
discovery research outsourcing – is where the CROs need to build a
solid presence, to accommodate its highly flexible requirements. If
CROs can deliver high quality data to its discovery customers, then the
market will certainly expand well beyond that for toxicology alone.
Challenges and opportunities
Within the next few years, preclinical services are likely to become a
significant component outsourced to India. One of the key challenges
will be to have state-of-the-art well-equipped facilities to develop
and provide discovery services. Leading Indian CROs have, in recent
years, invested in modern facilities that not only provide
toxicological services, but also a range of services required for
discovery, early and advanced preclinical development required for
identification of candidate molecules for clinical development.
Sourcing and retaining of talented researchers is a key determinant for
the efficient functioning of a biology-focused CRO. Identifying
researchers who work with the discovery mindset, yet adapt to the needs
of timely delivery of data, is a huge challenge. Development of
specialists for key components in the discovery chain, like those for
cell biology, pharmacology, DMPK and toxicology, is a prerequisite for
effective operations. Efficient facility management where the CRO is
nimble footed, intelligent and sensitive to respond quickly to the
changing requirements of discovery-focused projects, are some of the
essential requirements.
The animal experimentation is the cornerstone of the preclinical
domain. Currently most of the animal facilities are confined to rodent
and dog. There is an urgent need to extend these to primates, but
current government regulations do not encourage primate studies by the
CROs as a service portfolio. At present, there are only a few animal
facilities that have Association for Assessment and Accreditation of
Laboratory Animal Care (AAALAC) accreditation.
The sourcing of healthy and genetically characterized animals is an
absolute necessity for functioning of a CRO handling outsourced
biology. Regulations on importing animals have been streamlined.
Logistical issue of reaching out to multinational clients need to be
addressed by innovative methodologies.
Preclinical research at DRF
Dabur Research Foundation (DRF) turned into a full-fledged contract
research organization in the last couple of years, when it started
offering services in the niche area of discovery and preclinical
development.
The DRF has a young preclinical team which has prior experience of
discovery, development and commercialization of its own molecules.
The DRF model hinges on developing and provides high-end services in
cell biology and pharmacology, besides the complete battery of
toxicology, absorption, distribution, metabolism, elimination,
pharmacokinetics (ADME–PK) and analytical services. The services
offered are designed to support discovery projects of global clients in
several therapeutic areas inclusive of oncology, metabolic diseases,
immunomodulation and dermatology.
DRF has built a Central Innovation Research Team (CIRT) which
customizes and validates disease models required by clients for their
specific projects. These models are transferred to study teams, to take
the client projects rapidly through different milestones of their
preclinical development. DRF has developed several unique cell biology
in vitro- based efficacy models.
These enable critical decisions for clients in early stages of the
projects in a cost and time-effective manner. It also has a wide range
of in vivo efficacy models and unique toxicity models, for early
assessment of clinical safety of molecules. DRF operates in
pay-for-service as well as milestone payment models.
