The medical value story
The market is demanding a total value equation as a pre-
requisite for adoption of new therapies and rationalizing
existing therapies.
The clinical and economic value story need to go hand in hand
in developing the total medical value story of the medication.

Companion Diagnostics An emerging trend
One approach thats getting increased attention is the integration of
diagnostic tests to drive healthcare decision making.
Companion diagnostics are diagnostic products that can identify
patients most suitable for therapy, stratify patient risk, and guide
treatment modifications.

Companion Diagnostics: Success Stories and the Cost ofNot Doing
Herceptin (trastazumab) a monoclonal antibody active against the Her2-neu receptor.
The diagnostic test for HER2-neu determines which patients should receive the drug Herceptin.
The incorporation of the CD in Herceptin clinical trials was considered pivotal in the drugs approval and
uptake.
K-RAS for Erbitux and Vectibix The diagnostic test for K-RAS mutation can identify patients with colorectal cancer that will not respond to
treatment with panitumumab (Vectibix) and cetuximab ( Erbitux).
Patients with K-RAS mutations are not responsive to Erbitux and Vectibix. K-RAS testing is now routinely conducted in the U.S. for treatment selection of Erbitux and Vectibix.

Follow-up studies showed that
the delay lasted no more than
three months, and patientssuffered dangerous side effects.
FDA recommendation to remove

Commercializing Companion DiagnosticsFacilitators and Barriers
Rapid advances in science and technology
Emphasis by the FDA and EMEA on greater use of biomarkers and
companion diagnostics.
Evolving regulatory requirements for Laboratory developed Tests (LDTs)
and In-vitro diagnostics (IVDs).
Payers are beginning to require prior authorization for the most
expensive oncology therapeutics.
The biology gap.
Clinical cut-offs remain challenging.
Regulatory policies and pathways for therapies and companion
diagnostics are not aligned. Historically low reimbursement for diagnostics.
Companion diagnostics typically funded by Rx company which needs for
approval and/or adoption of new therapeutic.

Neurological Condition

TargetedTherapy forNeurological
condition
7/22/2019 03 Pfizer & UBC
14/31
Product X, currently in clinical trials, has the potential to be amongthe first disease modifying agents (DMAs) for a neurological
condition.
This therapy area is poorly served by marginally effective
symptomatic therapies. Costs associated with this neurological
condition are well acknowledged to be astronomical.
Test Z, under development by an imaging diagnostic manufacturer,
can identify the onset of the neurological condition, with greater
accuracy and less subjectivity than currently used tests.
A key question we sought to answer was: Should the manufacturer
of Product X acquire Test Z as a companion diagnostic?
To address this question, we designed a multi-stakeholder study
with KOLs, physicians and payers.
Case Study 1: Commercial Backdrop
7/22/2019 03 Pfizer & UBC
15/31
Case Study 1: Clinical Evidence for Test Z
Physicians welcome Test Ztouting its utility in informing
patients.
However, given the lack of
DMAs for the neurological
condition, payers feel Test Z
would have no clinical utility.
Physician to mention that their
treatment algorithm would not
change as a result of Test Z.
Once a DMA enters into the
market, Test Z would have a
higher clinical utility as it would
help in earlier diagnosis of the
condition.
Prior to Launch of DMA Post DMA Launch
Physicians and Payers value Test Z because it provides accurateand objective diagnosis, eliminating ambiguity in identifying
patients with the condition, and allowing for early therapy
intervention. But opinions vary in terms of timing of launch
7/22/2019 03 Pfizer & UBC
16/31
Case Study 1: Economic Evidence for Test Z
In the absence of a DMA,
payers considered the test to
be a net negative and were
unwilling to cover it.
It is a cost to the system
without a benefit whatsthe use?
If the patient still cannot
be treated, how does the
test help?
Once the DMA entered the
market, payers see its value in
providing rationalization for
restricted access to the DMA,
which was expected to be a very
expensive medication.However, even then, timing
of patients 1stpresentation is
key and may impact
coverage.
Prior to Launch of DMA After Launch of DMA
The entry of effective DMAs would change the game entirely forpayers and physicians.
7/22/2019 03 Pfizer & UBC
17/31
Case Study 1: Commercial Assessment
It became clear that the commercial opportunity was significantly
smaller than originally envisioned as coverage would be
restricted prior to availability of a DMA.
Post launch of a DMA, Text Z would have a higher commercial
opportunity.

Product A, is an oncology product, currently in development. Product A demonstrates a moderate overall survival (OS) and
progression free survival (PFS) over existing standard of care
(SOC), with a slightly higher toxicity profile.
Subsequently, Test B was identified that could identify the sub-set
patient population that were responders to Product A. Strong sensitivity and specificity of Test B.
Product A demonstrated a superior OS and PFS in responders
than in non-responders (significantly higher than without Test B).
A key question we sought to answer was: What is the incremental
value proposition of Product A + Test B, versus Product A alone?
To address this question, we designed a multi-stakeholder study
with oncologists and payers.
Case Study 2: Commercial Backdrop
7/22/2019 03 Pfizer & UBC
21/31
Case Study 2: Clinical Evidence for Test B
Product As high toxicity profilefor all patients outweighs its
moderate OS and PFS
benefits.
As a result, by itself, Product A
does not generate much
interest among oncologists and
payers.
Likelihood to recommend
and prescribe are low
Test B is a game changer,allowing oncologists to identify
likely non-responders, and
preventing them from needlessly
being exposed to Product As
toxicity with no therapeutic
benefit.
Product A, by itself Product A + Test B
Oncologists and Payers identify the clinical advantages of usingTest B - to identify treatment responders and non-responders to
Product A.
7/22/2019 03 Pfizer & UBC
22/31
Case Study 2: Economic Evidence for Test B
Payers question the cost
effectiveness of Product A,
particularly if it is prescribed for
a large number of patients who
will realize no therapeutic
benefit but experience toxicside effects.
Test B rationalizes use of
Product A in payerseyes,
making its approval and
reimbursement a slam dunk to
nearly all payers interviewed.
Product A, by itself Product A + Test B
Availability of Test B provides a cost-justification to the use ofProduct A making it more likely for Product A to get reimbursed
upon approval.

Case Study 2: Making the Case
Test B not only improves the value proposition of
Product A, but also allows Product A to command a
higher price point (than with Product A alone).
Product A, by itself could be priced below the current
SOCs.
With Test B, Product A can now be priced at par to SOCs
or at a 30% premium to current SOC (depending on thecountry).
So do the positives make a slam dunk case for a companion
diagnostic for Product A + Test B?
NOT SO FAST!
7/22/2019 03 Pfizer & UBC
25/31
Case Study 2: Making the Case
Many concerns were mentioned upon scrutinizing the
process required:
The logistics of using Test B are challenging.
Oncologists perceive shipping samples to specialty
testing labs as barriers that will reduce use
Clinical cut off points are difficult to understand and
interpret in clinical practice If a patient did not reach the clinically validated cut
off value, but came close, should the physician deny
treatment?
Moral hazard and liability issues were raised by both
physicians and payers.
The tests sensitivity and specificity were called intoquestion.
7/22/2019 03 Pfizer & UBC
26/31
Case Study 2: Making the Case
Ultimately, it comes to the pricing model.
How should the companion diagnostic combination be paid
for?
Should Test B be made available free of cost?
Thats unfair to the diagnostic test manufacturer.
Payers push back on paying for treatment costs related
to non-responders. Payers demand pay for performance model
Pricing model between oncology and diagnostic
company is tested.
Pricing model between manufacturers and payers falls
apart.
The million dollar question: while the companion
diagnostic makes clinical sensedoes it make
economic sense?

Closing Comments
The pairing of companion diagnostics and therapies present a
new way of patient treatment the right medication to the right
patient.
The market place understands the medical rationale
But the economics are as yet under-developed
Pricing models, risk sharing schemes, pay for
performance needs to be clarified
All stake holders need to benefit to facilitate progress:
Pharma / biotech companies
Diagnostic companies

Closing Comments
What will the future bring us?
Some safe predictions:
Advances in science will make more companion diagnostics
available.
Evolving regulatory guidelines and cost-constraints on health care
stakeholders will further drive the need for companion diagnostics
and therapies. What remains to be seen:
How will adoption models work?
Who will bear the costs of development and share the risk burden?
Who will educate and train physicians?
7/22/2019 03 Pfizer & UBC
29/31
Closing Comments
We believe that the commercialization process will remain
challenging but that industry has few alternative choices.
As seen in the two case studies, the commercialization of companion
diagnostics and therapies is not a straight forward process.
Several other examples speak to the challenges and good
technologies dying on the vine.
