Vulnerability
of
volunteer
depends
on
three
arms
of
triangle
and
his
own
handicap.
Studies have proved that malpractices are rampant in
clinical trials in India. Recent cases include unethical
testing of contraceptives, fertility drugs, cardiac
treatments and cancer medicines.
Analysts say that as many as two million Indians may
be enrolled in research trials by 2012.
A major problem is that a large proportion of
participants are illiterate and lured into trials by offers
of free health care and financial inducements. They
are often unaware of the benefits and risks of taking
part in a trial, and may not even distinguish between
treatment and research.

According
to
the

General
of

India
will
be

that

The
recruitment
of
children,
may
raise
concern
that
they
are
being
exploited.
• Children
are
considered
vulnerable
group
and
require
addi,onal
protec,on
as
research
subjects.
• Obtaining
the
assent
of
a
child
and
the
permission
of
a
parent
or
guardian
is
not
the
same
as
obtaining
informed
consent
from
a
competent
adult
.
Although
it
seems
reasonable
to
offer
payment
for
the
=me
and
inconvenience
of
par=cipa=ng
in
research,
children
and
their
families
may
be
unduly
influenced
by
the
offer
of
payments
that
may
amount
to
several
hundred
dollars
or
may
include
gir
cer=ficates
to
toy
or
record
stores.
According
to
the
ICMR’s
guidelines,
“…
payments
should
not
be
so
large
or
the
medical
services
so
extensive
as
to
make
prospec=ve
par=cipants
consent
readily
to
enroll
in
research
against
their
be^er
judgment,
which
would
then
be
treated
as
undue
inducement.”

Orders
related
to
clinical
trial
The phenomenal growth in clinical trial
unfortunately has created a situation
where regulatory mechanism cannot
keep pace. Ethical review is now
mandatory for clinical trial but there is
little review of the functioning of the
ethics committee by the DCGI. There
is little interaction between ethics
committees in different locations,
thereby allowing the practice of
‘Ethics Committee Shopping’, –
sponsors whose trials are rejected by
one ethics committee approach a
different centre for approval.

REGULATOR
VOLUNTERS
1. Huge patient base with diversity of
diseases
2. The average cost of drug discovery in US
is estimated at US$ 800 million. Cost of
conducting clinical research in India is
much lower as compared to the developed
countries. Drug companies can save up to
two – third of overall cost of conducting
trials in India compared to the west.
4. English-speaking technical workforce,
good IT infrastructure and low
infrastructure costs can reduce
expenditures for clinical trials by as much
as 60 percent.

• Inadequate source documentation.
• Protocol noncompliance.
• Delinquent or inaccurate data

sometimes the number of patients
might be the limiting factor for a

• Physicians are not as familiar with
the clinical trial process as they are in
the West.
VOLUNTERS
Unseen Concern and Challenges
a) Regulators needs to generate effective monitoring mechanism for continuous
evaluation of trials throughout the study period ensuring regular and periodic
scientific and ethical review. Strategies should be developed to prevent fudging
the data.
b) Studies should follow strict adherence to ethical guidelines.
c) All persons involved in study should undergo basic training concerning
counselling and preventive strategies.
d) All persons should be recruited in any study after ensuring receipt of proper
informed consent for participation.
e) Adequate care and protection should be provided to vulnerable groups.
f) Community involvement at all stages of the studies.
g) Sharing results with all persons involved in research.
h) Ensure global justice, narrowing gap between developed and developing worlds.
CONCLUSION
Contd..
l) To favour the promotion of clinical trial in India (Developing
countries), restrictions are necessary to ensure that the health
of the trial subjects is adequately protected in case of any
contingency. Comprehensive health insurance for all the
participant volunteers must be provided by the sponsorer in
the form of a viable bank guarantee ensuring the obligation of
any direct / indirect consequences.
m) If the intervention being tested is not likely to be affordable in
the host country or if the health care infrastructure cannot
support its proper distribution and use, it is unethical to ask
persons in that country to participate in the research, since
they will not enjoy any of its potential benefits.
n) Clinical trials sponsored or regulated by external agencies
should be limited to those that are responsive to the host
country’s health needs
CONCLUSION
