EU Risk Management Plan (EU-RMP)
• Introduced to meet demand for strengthened coordination of on-going
safety assessment and risk minimization post marketing
- Limitations of safety data from trials increasingly appreciated
- High profile safety withdrawals (e.g. rofecoxib)
- Increasing pressure for early access to new medicines
• Idea first proposed by Japanese Ministry of Health Labour & Welfare in
2001, backbone by ICH E2E Pharmacovigilance Planning
ICH E2E concept paper September 2002

EU Risk Management Plan (EU-RMP)
• Integral part of regulatory approval of biologicals (including biosimilars),
since November 2005
• Requirements described in guideline on good pharmacovigilance practice
(GVP), formerly Volume 9A guideline
• EU-RMP comprises three main sections:i. Safety specification
ii. Pharmacovigilance plan
iii. Risk minimization plan
EU-RMP, Safety specification
• Synopsis of safety profile on basis of non-clinical and clinical data
• Defining important safety concerns: 1. Important identified risk
- Adequate evidence of association (e.g. heart failure)
2. Important potential risk- Basis for suspicion of association (e.g. malignancies)
3. Important missing information- Information about safety which is not available (e.g. renal impairment)
Results from 9 biologicals and 9 small molecules (Nov 2005 – May 2007)

EU-RMP, Pharmacovigilance plan
• Structured plan to identify/ characterize safety concerns, including:- Further characterization of risk factors
- How data on important missing information will be collected
- Investigate whether a potential safety concern is real or not
• For each safety concern, the planned PhV activities are listed: - Routine pharmacovigilance
- Additional activities
i. Post-authorization safety studies
ii. Drug utilization studies
iii. Registry studies
iv. …
Giezen e.a. Drug Safety 2009
EU-RMP, Risk minimization plan
• For each safety concern the need for addition risk minimisation measures is
determined - Routine risk minimization (information in product information)
- Additional risk minimization:
i. Educational programs
ii. Controlled distribution
• Example of risk minimization activities
for Soliris (eculizumab)
EU-RMP for aflibercept (Eylea)

EU-RMP within life cycle management
• Ongoing benefit/risk assessment during full life cycle of drug - Rather than point of approval being last point of major regulatory action
• Hence, EU-RMP should evolve as safety profile becomes further defined - Regular updates within product’s life cycle
• No insight in advancement (knowledge gain) over time, and contribution of
RMP to public health
Study aim
Primary aim:
To describe the evolution of the RMP after marketing authorization, by
quantifying changes in listed safety concerns
Insight into the knowledge gain of medicinal products over time
Secondary aim:
To study factors associated with change, in particular with respect to the
additional pharmacovigilance actions proposed
Insight into contribution of RMP to public health
Study methods
• Cohort study
- Study population: 56 new medicinal products (Nov ‘05 – Dec ‘09)
- Follow-up until Dec ’12
• Outcomes of interest
- Change in safety concern
- Newly added concerns
Study methods (2)
• All baseline RMPs and subsequent RMP updates through EMA
• Data extraction from RMPs (baseline/ updates)
- Information on determinants (categorized)
- Former and current status of safety concern collected for every RMP update
Preliminary results
• 23 biologicals initially selected
from community register
- 17 biologicals included
- 253 baseline concerns
• Median follow-up:
- 49 months (range: 35-75)
- 8 RMP updates (4-11)
23 biologicals identified over period: Nov ‘05 – Dec ‘09
20 biologicals eligible for inclusion
18 biologicals eligible for follow-up
Excluded: - Vaccines (n=2)- Cell therapy (n=1)
Excluded: - No RMP (n=1)- Poor quality (n=1)
Followed-up until 31 Dec ‘12
Excluded: - No follow-up (n=1)
17 biologicals included;safety concerns at baseline:
49 Identified risks99 Potential risks
103 Missing information
Preliminary results (2)
• 43 out of 253 baseline safety concerns changed during follow-up:
– 20 safety concerns were omitted
– 19 potential risks changed to identified risk
Preliminary results (3)
Reason for omitting safety concern (determinant of change):
- 9 resulted from completion of PhV activities in the RMP:
• Completion of clinical trials (n=8), e.g. use in paediatric patients,
interaction with vaccination (vaccination response)
• Completion of active surveillance study (n=1), for safety in home
administration
– 3 resulted from completion of studies outside RMP
– 4 upon reassessment / no new data on risk
– 4 unknown
Preliminary results (4)
Timing of missing information being omitted (n=20)
Preliminary results (5)
• During follow-up, 59 concerns newly added for the 17 biologicals:
– 21 identified risks, 23 potential risks, and 15 missing information
• Reason/ data source* for newly added risk:
* Unknown for 6 products
Source Frequency Notes
Clinical studies 20 (34%) 12/ 20 studies were proposed in RMP
Spontaneous reports 10 (17%)
Related to new indication 9 (15%) e.g. risk due to characteristics (co-morbidities) of new population
No new data 6 (10%) e.g. upon EMA request, study reanalysis
Data from other products 3 (5%) Class effects
Other/combination 5 (9%)
Discussion
• Risk Management Plans can play a pivotal role in the life cycle
management of biologicals
– Ongoing B/R assessment post marketing
• EU regulatory framework has provided backbone
– Integral part of approval of new drugs
• Establishment of safety concerns and required pharmacovigilance
and risk management activities
– Regular updates during life cycle once safety profile becomes further
defined
Discussion
• The observed development of RMPs after approval supports their
role in a medicine’s life cycle
• The vast majority of concerns from baseline remain unchanged
– 20 out of 253 baseline concerns (8%) omitted during life cycle
– Relative short follow-up might not allow for sufficient characterization of
concern (median = 49 months)
– Particularly difficult for regulators to decide that a safety concern might
be omitted from the RMP
• Five years post-approval, the emphasis seems to be on newly
emerged concerns, rather than on changes in baseline concerns
