The older patient.
Can the EMA assist in determining
cost-effectiveness of treatments?
Presented by: Francesca Cerreta – EMA Safety and Efficacy of medicines
An agency of the European Union
What does EMA do?
The Agency is responsible for the scientific evaluation of
applications for medicines in the European centralised procedure.
This benefit-risk assessment forms the basis for EU marketing
authorisations.
What do HTA bodies do?
HTA bodies carry out their own assessments of medicines once
they have received a marketing authorisation. HTA bodies
compare the relative effectiveness of medicines and take their
financial cost into account.
This can lead to differences in the types of studies needed to
support the assessment carried out by regulators and HTA bodies.

EMA / HTA Dialogue
• Mandate from High Level Pharmaceutical Forum in 2008: EMA,
Member States and HTAs should cooperate so that Assessment
Report can contribute to relative effectiveness assessment (EPAR
improvement project)
• Cross Border healthcare directive 2011/24/EU: support of the
collaboration activities of the voluntary network of HTA agencies
• Exchange on scientific / methodological principles between
Regulators and HTAs beneficial to avoid double-standards:
• Parallel Scientific Advice/Early dialogue
• Consultation on Guidelines (now routine)
• Relative effectiveness assessment
• Databases for post-marketing data generation
• Specific measures for orphan medicines

Parallel HTA-EMA Scientific Advice - examples
 Diabetes, Heart Failure,
 Alzheimer’s, Depression,
 Lung Cancer, Breast Cancer, Melanoma, Pancreas-Ca, Mesothelioma
 Asthma, Rheumatoid Arthritis
 Multi-resistant Infections,
 Food Allergies
 Orphan conditions
• The majority had new mechanisms of action (new monoclonal
antibodies, new chemicals, tumour vaccines)
• HTAs and payers from UK, Sweden, France, Italy, Netherlands,
Spain, Germany, Belgium
• 14 big companies, 2 SMEs

First experiences with Parallel Regulatory/HTA Scientific Advice
Note: based on first 11 procedures.
Some discussion examples
•Is impact to the caregiver an important piece of the value proposition when
evaluating a treatment for prodromal Alzheimer’s disease?
•Advice on selection of instruments in the clinical trial to capture the burden
to the caregiver (Dependence Scale)?
•Value of MRI imaging as indicator of progression of atherosclerosis?
•If final data on cardiovascular events cannot be provided for diabetes
preauthorisation what alternatives are there for the company from the
Regulators and HTA point of view?
•The cost-effectiveness of the product will be strongly influenced by the
extent to which treatment prolongs the prodromal Alzheimers disease
phase, delaying progression to more costly states associated with
potentially lower quality of life and greater cognitive impairment. This
would potentially result in a greater proportion of residual life being spent
with lower disability and lower medical costs. However, delaying
progression may also extend life expectancy and time in the moderate and
severe disease states, which could result in higher total lifetime costs and
reduce the cost-effectiveness of treatment. Modelling will be necessary to
project out the implications of potential post-trial scenarios. Advice on
approaches taken to establish the most plausible scenario and required

analyses to support the plausibility of the scenario?
What about older patients?

* Extracted from "L'uso dei farmaci in Italia 2011" and Italian census 2011
• Major consumers of medications
• ADRs hospital admissions significantly higher in older people
• Incidence on pharmaceutical and healthcare costs - sustainability

EMA Geriatric medicines strategy (2011):
TWO PRINCIPLES
Medicines used by geriatric
patients must be of high
quality, and appropriately
researched and evaluated..
for use in this
population.
Improve the availability
of information on the
use of medicines for
older people

Potential questions
•
•
•
•
•
Is the clinical trial population representative of real-life?
Cost-effectiveness over established (generic) comparator
What do we know about the risk of polymedication?
Will frail patients have the same benefit/risk profile?
Costs and benefits for individual and society?
Challenges
•
•
•
•
Balancing risk of involving frail/older patient in clinical trials
Creating an “orphan” older population? (not authorising/not reimbursing)
Design appropriate pharmacovigilance for unknowns
Communicating to reduce inappropriate prescription
The EMA has not so far received a parallel SA/HTA request on elderly (except
Alzheimer)
BUT
Our mission is to make sure that medicines are assessed as safe and effective for
the population of use, and the assessment results are communicated appropriately

Guidelines
• Geriatric Expert Group and HTAs will routinely comment
on guidelines prior to their release.
• Points to consider on Frailty should be developed.
• Geriatric formulations guideline under development
Scientific Advices/Scientific Advisory Groups
• Geriatricians have been involved in a number of these
• A member of the GEG is now member of the Scientific
Advice working Party

New EU pharmacovigilance tools
Tools relevant to reaching to real-life:
• Legally binding Risk Management Plans for all new products
• Legally binding post-authorisation safety studies, when justified
• Legally binding post-authorisation efficacy studies, when justified
• Confirm a risk
• Quantify a risk
• Fill a knowledge gap, eg. efficacy in sub-groups
• Off-label use
• Measure the effectiveness of risk minimisation
• Legal responsibility to measure the effectivess of risk
minimisation
