This document discusses Canada's orphan drug regulatory framework. It begins by defining orphan drugs as treatments for rare diseases affecting fewer than 5 in 10,000 people. It outlines challenges in developing and accessing orphan drugs, including small patient populations that make clinical trials difficult. Health Canada is proposing a framework to improve orphan drug availability through an accelerated review pathway, early advice to sponsors, transparency throughout the drug life cycle, and collaboration with international regulators and health technology assessment bodies. The key components of the framework include orphan drug designation, written regulatory advice, modernized market authorization applications, post-market oversight, and transparency.

2. Orphan
drugs
Orphan
drugs
are
used
to
treat
rare
diseases
which:
• are
life-‐threatening,
seriously
debilita.ng
or
both
serious
and
chronic
in
nature
• affect
a
rela.vely
small
number
of
pa.ents
(less
than
5
in
10
000,
but
typically
closer
to
1
in
100
000)
• are
oRen
gene.cally
based,
onset
at
birth
or
early
childhood,
lead
to
a
shortened
life-‐
span
• reduce
quality
of
life
and
place
significant
challenges
on
pa.ents,
caregivers
and
the
healthcare
system
• are
difficult
to
study
because
of
the
small
pa.ent
popula.on
2
3. Challenges:
Limited
pa?ent
popula?ons
and
treatments
3
There are more than 7,000 rare diseases
Rare diseases affect 1 in 12, or nearly 3 million Canadians
Diagnosis is challenging and can take years
Once diagnosed, there is likely no treatment available, or limited treatments for the patient
4. Challenges
–
Orphan
drug
development
and
pa?ent
access
4
Orphan
drugs
are
challenging
to
develop:
Small
pa.ent
popula.ons
make
it
difficult
to
conduct
clinical
trials,
especially
in
na.ons
without
large
pa.ent
popula.ons
LiXle
is
oRen
known
about
the
rare
disease
Researchers
and
drug
sponsors,
in
the
past,
did
not
have
incen.ves
to
invest
in
developing
drugs
for
rare
diseases
Once
developed
and
approved:
Orphan
drugs
are
oRen
costly
Pa.ents
across
Canada
may
not
have
equal
access
to
approved
orphan
drugs
5. An
Orphan
Drug
Framework
for
Canada
A
Regulatory
Framework
for
Drugs
for
Rare
Diseases
(Orphan
Drugs)
proposed
to
-‐
• channel
orphan
drugs
into
a
federal
regulatory
pathway
designed
to
improve
market
availability
in
Canada
• draw
on
new
post-‐market
and
transparency
powers
from
Vanessa’s
Law
• reflect
Canada’s
legisla.ve
and
regulatory
context,
while
aligning
where
possible
with
other
interna.onal
regulators’
orphan
drug
frameworks
• encourage
the
genera.on
of
knowledge
regarding
rare
diseases
in
drug
development
through
an
open
and
transparent
regulatory
environment
and
the
provision
of
advice
to
companies
developing
orphan
drugs
• allow
for
accelerated
market
authoriza.on

Involvement:
Exploring

• Pa.ent
input
can
add
value
to
the
evalua.on
of
human

as

• Current

Health
Canada
is
currently
exploring
and
examining
the
most
effec.ve
ways
to
involve

in
the

• Not

Pilot
Project
• Pa.ent
Involvement
pilot
project
launched
in
2014
• Orphan
drugs
context
was
considered
a
good
star.ng
point
• Pilot
was
intended
to
be
a
simula.on
of
how
input
could
be
obtained
and
used
to
help
inform
Health
Canada’s
benefit/risk
assessment
• Two
drugs
were
involved
in
the
pilot
(one
biologic
and
one
pharmaceu.cal)
• Input
was
sought
through
online
ques.onnaires
designed
to
gather
the
perspec.ves
of
pa.ents,
caregivers,
pa.ent
groups
and
health
care
professionals.
Ques.ons
related
to
quality
of
life,
experience
with
other
therapies,
unmet
need,
and
risk
tolerance.
• Results
–
more
experience
is
needed;
reviewer
and
pa.ent
group
training
would
be
useful,
.ming
of
request
for,
and
receipt
of
input
is
important,
considera.on
should
be
given
to
establishing
criteria
for
when
to
request

that
would
be
of
most

to
both

and

13. Vanessa’s
Law
• Overall
policy
objec.ves
are
to:
– Provide
a
range
of
pre-‐
and
post-‐market
regulatory
tools
that
enable
the
safety
oversight
of
therapeu.c
products
throughout
their
lifecycle;
and
– Promote
greater
confidence
in
the
oversight
of
therapeu.c
products
by
increasing
transparency.
• Vanessa’s
Law
amends
the
Food
and
Drugs
Act
improving
Health
Canada’s
ability
to:
– collect
post-‐market
safety
informa.on
– take
appropriate
ac.on
when
a
serious
risk
to
health
is
iden.fied
• These
amendments
are
par.cularly
important
in
the
rare
disease
context
where
oRen
.mes:
– many
of
the
pa.ents
impacted
are
vulnerable
paediatric
popula.ons
– informa.on
on
the
drug
and
the
disease
is
some.mes
limited

key
points:

Many orphan drugs available in PMPRB7 countries are approved for
use in Canada
Health Canada approved 9 of the top 10 select orphan drugs
Orphan drugs not available in Canada represent a small share of the
international market: some were accessed through the Special Access
Program, while others were approved by Health Canada in 2015
