AGENDA
EFFECTIVE LATE STAGE
PATHWAYS FOR
BIOSIMILAR PRODUCTS
• Enhancing operational efficiencies of
Late Phase Biosimilar trials
• Optimizing patient recruitment and
retention strategies
• Investigator interest
• Acquiring the reference product and changes in

Filings
 Create aggressive defensible
development
plans and gain
Agency buy-in
 Maximize ROI
through a compelling value
proposition
• Overcome local regulatory and operational hurdles
• Optimise patient access – “global reach”
• Optimize operational efficiencies and risk
management via integrated technologies
• Direct experience in the preparation
and submission
of Biosimilar CTDs that resulted in
approval
• Negotiation of Phase IV
commitments (risk management)
• Implement risk sharing program that drives speed & efficiency
• Implement dedicated leadership & expertise model

BIOSIMILAR COMPOUND GLOBALIZATION ROADMAP
Phase III in US, Europe & Asia (>500 subjects)
• Therapeutic equivalence (safety and immunogenicity)
• 2 arms
• Investigational product – xx subjects
• Reference product (EU sourced) – xx subjects
Global market access
• Leverage the Phase I and Phase III study to apply Asia & EU MAA
• Leverage EU MAA to apply for most emerging market MAA without or limited
additional studies (local patients required in India, Russia, Mexico, Japan, Korea)
Phase I & Phase Ib PK in a particular country
• PK Equivalence in specific patient population
• 2 arms
• Investigational product – xx subjects
• Reference product (EU sourced) – xx subjects

ACCELERATING THE PHASE III STUDY
• Conservative Plan (Long overall timeline, Low risk if true no similarity)
• Aggressive Plan (Short overall timeline, High risk if true no similarity)
• Relative aggressive and Control the risk
• Aggressive Plan and minimized the overall sample size

OPERATIONAL CONSIDERATIONS
 Understanding the regulatory environment
• Early engagement of regulators (open to negotiation)
• Manage the specific requirements of IRB/EC
– Work closely with sites, lab to collect required documentation
• Identify phase III sites in parallel with preclinical/Phase I work
– RA and IRB/IEC submissions made in parallel
– Consider early Phase III submissions
• Appropriate patient population and sample size
– Required designs not set in stone; early health authority input is critical
– Limited relevance of original innovator’s basis of approval
– Safety as a factor for sample size
 Knowing the “right” sites and engaging the investigators

7. © 2017 PAREXEL INTERNATIONAL CORP. / 7
OPERATIONAL CONSIDERATIONS (2)
 Ensuring quality data and compliance
• Contingency plan in monitoring plan for missing data
• Clear guidelines on SD requirement, CRF completion and protocol deviation management
• Leverage data driven monitoring technology & data surveillance tools
• Comprehensive/continuous training, tools and lessons learned to sites
 Identifying the right clinical endpoints
• Include biomarkers or other surrogates predictive of clinical efficacy
 Selecting the reference products
• Obtain from a combination of sources
• May need to demonstrate in-vitro comparability to multiple sources

KEY SUCCESS FACTORS IN PATIENT ENROLMENT
Proactive engagement with sites
 Accelerate site start-up and site activation
• Weekly Prescreening log
• Offer site support – e.g., via SMOs
• Study level documentation in English, localized in each country
 Investigator relationship and retention is key
• Bi-weekly enrollment status letter to all PIs, and Weekly booster call by CRA
• Engage the sites at identification and qualification phase
• Emphasize the study benefits including the extension study
 Patient and health care provider confidence
• Perception that biosimilars have less rigid pre and post market data requirements
• As a new category of drug products, need to educate on safety and efficacy
Make effective use of Asian countries
 Leverage on established footprint and infrastructure

IDEAL SITE CRITERIA
Key Factors
• Does the site have this patient population?
• Is the site correctly aligned to the protocol
criteria?
• Investigators with affiliation to country
therapeutic groups/disease networks
• The number of studies that PI conduct in
parallel?
The “Right” Sites
• Sites that routinely treat specific indication patients
with biologic agents
• Sites that PAREXEL has a working relationship with,
or has pre-identified, including good-performing sites
from the previous biosimilar studies
• Investigators with affiliation with strong network of
indication working groups
• Centers that have an adequate facility to conduct
clinical trials for patients (e.g. chest x-ray, ESR
measurement etc.)
PATIENT EXPERIENECE & TECHNOLOGY PATIENTS MAKE INFO MORE TRANSPARENT,
ACCESSIBLE, PATIENT FRIENDLY
• Improve participation
& experience
• Reduce patient
burden
• Innovate data capture
Difficult to:
• Identify sites
• Engage in a
meaningful
conversation

PATIENT ENROLLMENT/RETENTION STRATEGY
Newsletters Referrals
Patient Materials /
Others
Resource /
Compensation
Booster Actions
• Give a heads-up in
advance to
investigators to
assign sufficient
Sub-Is/ SCs
• Increased
investigator fee for
high enrollers
considering the
workload of site staff
• Assign more CRA
hours for high
recruiting sites to
provide more site
support.
• Compensations to
patients for
transportation fee
• Recommend
‘Meetings within
hospital’ to create
awareness amongst
colleagues on regular
basis.
• Laminated charts for
trial design and trial
flow chart for easy
reference
• Dear Doctor letter to
other doctors within
the country explaining
Study
• Prepare and distribute
newsletters on a
regular basis with up
to date study updates
• Highlight enrollment
• Newsletters to
address enrollment
issues and major
changes/ updates to
the study procedures
• Targets - high
enrollers –
Appreciation and
Recognition!!
• Patient retention
status update
• Close contact with
the sites weekly
during start-up to
keep continued site
engagement
• PL/COL/sponsor
visits sites, discuss
with PI to motivate
• Interim SC or local
investigator meeting
(experience sharing
from high recruiters
or good performance
sites)
• To share with PI the
publication policy
during SIV, if
applicable
• Patients facing tools:
poster, study
brochure, etc.
• Identify Back-up sites
at the beginning and
get those initiated if
applicable
• Patient retention
materials;
appointment
reminder card, etc.

GAME CHANGER
• Race to launch biosimilar products will intensify
• Careful strategic planning and understanding of operational challenges
are critical
• Innovative trial designs needed – to reach biosimilar endpoints sooner
• Leverage on innovative platforms (Data Driven Monitoring) to optimise
study execution and deliver results of high scientific and statistical
integrity
