Status for Chronic Pain:
•
MN-166/AV411 is enabled to go directly to Phase 2b clinical development
•
MN-166/AV411 mechanism of action is novel and thus complimentary to
current pain treatments,
and has both stand-alone and adjunctive utilities
•
Majority of potential pharma
partners are strategically committed to new pain therapies
•
MN-166/AV411 has an attractive development timeline and long term
exclusivity Status for Drug Addiction/Opioid
Withdrawal:
•
Announced positive safety/efficacy results from Phase 1b/2a study in Opioid
Withdrawal (12/10)
•
UCLA initiated Phase Ib
study for Methamphetamine Addiction (9/10)
Status for Multiple Sclerosis:
•
MN-166/AV411 requires significant funding for future trials
•
Phase 2 data were at doses that are below maximum utility
•
Most attractive option may be Progressive MS which would require
an additional Phase 2b
clinical trial

Limitations of Current Therapies
What are the limitations of current therapies for acute exacerbations of
asthma?
Limitations of Inhaled Therapies:
•
Bronchoconstriction:
inflammation
and
bronchoconstriction
result
in
insufficient
air
flow to get good drug deposition in the lungs
•
Mucus Plug Formation:
mucus secretion and the formation of thick mucus plugs
can cause persistent airflow limitation
•
Albuterol
Non-Responders:
not
all
patients
benefit
from
albuterol
Limitations of Current Intravenous Therapies:
•
Safety:
currently
available
options
(e.g.
epinephrine,
terbutaline)
have
significant
cardiovascular
risks
at
doses

There was a reduction in the hospitalization rate
among patients treated with MN-221.
•
Overall,
improvement
in

greater
for
patients
receiving MN-221 than placebo.
•
A dose of 1,200 µg

Potential Development Opportunity:
•Exacerbations of
COPD |
 ©
MediciNova, Inc. 2011
28
Chronic Obstructive Pulmonary Disease
•
Chronic obstructive pulmonary disease (COPD) is a progressive
disease that causes airflow blockage and breathing-related problems.
•
COPD includes two main conditions:
emphysema and chronic
obstructive bronchitis.
•
Cigarette smoking is the leading cause of COPD.
•
An estimated 10 million adults had a diagnosis of COPD in the U.S. in
the year 2000.
•
The prevalence and age-adjusted death rate for COPD increased
more than 30 percent since 1980.
•
The direct/indirect costs related to COPD amounted to approximately
$42.6 billion in the U.S. in 2007.

A COPD exacerbation
is a sustained worsening of the
patient's condition, from the stable state and beyond
normal day-to-day variations, that is acute in onset.
COPD exacerbations are associated with a significant
increase in mortality, hospitalization and healthcare
utilization.
1.5 million hospital emergency department visits
765,000 hospitalizations
Average length of stay 7.4 days*
Average cost ~$32,000*
119,000 deaths
COPD Exacerbations
COPD patients are generally more ill than asthmatics with
overall higher hospitalizations and mortality.

Published evidence
•
It has been demonstrated that airway abnormalities extend from the proximal to the most
distal airways in asthmatics, and in severe stable asthmatics it has been
postulated that one reason that they are difficult to control
is
that
inhaled
particle
(drug)
deposition
in
the
distal
airways
is
impaired
(1).
•
The bronchoconstriction, inflammation, and mucus plugging that occur during an acute
exacerbation of asthma will magnify this problem. Modeling of airflow patterns
in patients with acute asthma demonstrates that
airway
resistance
is
twice
as
high
during
the
exacerbation
than
after
recovery.
Furthermore,
the
airflow
is more profoundly affected in regions where the effects of asthma are significant
(2). •
Chronic
Mucus
Plug
Formation:
In
severe
asthma,
mucus
secretion
and
the
formation
of
inspissated
mucus
plugs can cause persistent airflow limitation (3).
•
Taken together, delivery of aerosolized medications to the distal airways is negatively
impacted during an acute asthma exacerbation.
Anecdotal evidence
•
The emergency room doctors in our studies and key opinion leaders we have spoken to all
believe in the concept
of
"intravenous
beta
2
agonist"
to
treat
acute
exacerbations
of
asthma.
They
have
all
cited
the
fact
that if
a patient is having difficulty breathing, the patient cannot fully inhale
medicine. MN-221 may improve efficacy over current
standard of care due to its route of
administration

•
MediciNova
has preclinical data and clinical data which demonstrates
the safety of MN-221.
•
In summary, we have not seen clinically significant safety concerns
with MN-221.
•
According to interviews of emergency room physicians, less-selective
injectable
beta agonists such as epinephrine and terbutaline
are not
commonly used to treat acute asthma.
The main reason they are not
used more often is due to safety concerns, particularly cardiovascular
side effects.
MN-221 may result in fewer cardiovascular
side effects than the current standard of care

•
Since the average hospitalization cost is $6,477 in the US, the payor
would save this amount for each hospitalization prevented.
•
Since US hospitals lose money on the typical asthma hospitalization
due to low reimbursements from Medicaid and HMOs, hospitals
would also make more money for each asthma hospitalization
prevented.
MN-221 may reduce health care expenses
by reducing the hospitalization rate
