Evidence submitted by Pfizer (NICE 47)
RECOMMENDATIONS
1. The Health Select Committee needs to
critically evaluate the impact of health technology assessment
(HTA) as currently practised by NICE on the sustainability of
pharmaceutical innovation in the UK.
2. NICE should commit to establishing a
process for defining the evidence, expected to be necessary at
the time of approval, to demonstrate cost-effectiveness and value.
That process must include the pharmaceutical company and allow
for collaborative interaction in defining the target evidence
for promising new technologies.
3. Pharmaceutical companies should be permitted
to attend appraisal committee meetings with the same rights as
all other stakeholders.
4. Appraisal committee hearings should be
held in public and all calculations and models should be made
available to stakeholders in advance in a format that enables
full and proper independent audit.
5. NICE should revise its appeal process
so that it considers the merit of the decision, as well as the
process, and the appeal process should be conducted and chaired
by an independent panel.
6. NICE needs explicitly to recognise the
inherent limitations of using quality adjusted life years (QALYs)
to measure the value of medicines.
7. Further research is required to develop
more robust, inclusive and transparent methodologies for valuing
medicines. These need to acknowledge the variations in patient
response to medicines and the limitations of applying population
level models to individuals.
8. NICE needs to broaden the perspective
of appraisals so that they include costs and savings that accrue
to patients, caregivers, and wider society.
9. NICE needs to recognise the inherent
uncertainty in all economic evaluations and not to place undue
emphasis on these results when developing guidance.
INTRODUCTION
1. The National Institute for Health and
Clinical Excellence (NICE) was created in 1999, and has established
a reputation as one of the leading HTA organisations in the world.
Pfizer supports the objective of NICE to raise the standards of
health care in the UK and its stated aim of supporting the diffusion
of innovation.
2. NICE has appraised approximately one
hundred technologies, of which, approximately 70% have been medicines.
However, despite the often high profile and controversial nature
of these appraisals, they cover a relatively small percentage
of annual NHS spending or activity.
3. Pfizer has been involved in over a dozen
NICE appraisals, including the ongoing assessments of treatments
for Alzheimer's disease and age-related macular degeneration.
4. The theory of Health Technology Assessment
(HTA) has intuitive appealthe NHS clearly needs to use
its resources wisely, and Pfizer recognises that NICE can play
an important role in guiding healthcare professionals towards
treatments that offer the most value to patients and the NHS.
5. However, there remains a significant
gap between the theoretical benefits of HTA and the reality of
medicines' development. Indiscriminate application of HTA has
the potential to have a significant and adverse impact on public
health and pharmaceutical innovation in the UK.
6. Pfizer welcomes this opportunity to contribute
to the Committee's inquiry. In this short submission, we outline
reasons why Pfizer believes that NICE's decisions are often contentious,
outline significant ongoing concerns and make proposals that would
better safeguard the interests of patients, the National Health
Service (NHS), taxpayers and the research based pharmaceutical
industry.
REMOTE DECISION
MAKING AND
LACK OF
ACCOUNTABILITY
7. The allocation of public money will always
have a significant political dimension. In healthcare, where the
consequences of treatment being provided or withheld can have
profound implications for individuals, these decisions are often
highly emotive.
8. Historically, treatment decisions in
the UK were made by physicians, often with input from patients.
The approach that NICE has introduced makes greater use of population
level assessments of health gain, predominantly undertaken by
health economists. While population assessments can be useful,
they do have significant limitations including their failure to
reflect the specific needs of individual patients.
9. NICE attempt to include the views of
patients and doctors in their appraisals. However, the processes
for doing so have been regularly criticised as being insufficient
(Milewa, 2005; Bridges 2007). Importantly, it is often difficult
for patients to present information in a form that is able to
be fully incorporated into highly data driven methods adopted
by NICE appraisal panels. As a result, concerns have been raised
that decision making relies too heavily on the academic assessments.
This has an adverse impact on the relationship between patients
and their doctors who are charged with implementing NICE guidance.
10. Another concern with over-reliance on
economic assessments is that wider implications of decisions about
which groups of patients to treat are not formally scrutinised
through any political process. Lines of accountability are unclear
and are a cause of frustration when patients are denied access
to treatments.
IMPACT ON
INNOVATION
11. Pfizer believes that given the substantive
costs and time required to develop new medicines, any system of
medicines assessment should be stable and lead to predictable
outcomes. Despite NICE being in existence for eight years, many
of its appraisal decisions remain contentious and unpredictable;
leading to high levels of frustration for patients, professional
groups, patient groups and pharmaceutical companies.
12. One of the principles of HTA is to compare
new medicines with current standards of care. New classes of medicines
must bear significant research and development costs in order
to satisfy the requirements of regulatory and HTA organisations.
Generic medicines have no such requirements and therefore, can
be provided to the NHS at a significantly lower price. Thus, in
disease areas where current practice is a relatively cheap, off
patent medicine, such as in many areas of cardiovascular disease,
mental health and respiratory illness, HTA discriminates against
pharmaceutical innovation.
13. One argument put forward for this approach
is that it creates incentives for pharmaceutical companies to
concentrate their research efforts in areas of unmet clinical
need rather than in areas where cheaper older medicines are already
available. This thinking appears to have underpinned recommendations
in the recent Cooksey Report into Medical Research in the UK as
well as the Office of Fair Trading's market study into the Pharmaceutical
Pricing and Regulation Scheme (PPRS). However, it is flawed for
two reasons and, as such, risks damaging the future of medical
innovation to the detriment of both industry and patients.
First, the notion that if treatments
exist within a given disease area, then there is no longer clinical
need, is simply false. Cardiovascular disease is still the biggest
killer in the Western worldand is increasingly a major
problem in the developing worldand yet, treatments exist.
We need more and better treatments in cardiovascular medicine,
not fewer.
Second, associating value only with
breakthrough pharmaceutical innovation is fundamentally flawed.
History shows that disruptive pharmaceutical innovations are rare
and that medicines normally evolve incrementally over time (Wertheimer,
2005; Williams 1999). Furthermore, and perhaps most importantly,
within a new area of medical innovation, the first medicine is
rarely the best.
14. Unless this is addressed, then there
is a real prospect that no new medicines will be introduced in
the UK into disease areas where common practice is to use off
patent medicines. By 2020, this could realistically extend to
all disease areas.
Recommendation 1
NICE EVALUATION PROCESS
15. The credibility of NICE guidance relies
on there being open, transparent decision making during the appraisal
process that involves all stakeholders. Pfizer recognises the
appraisal process has evolved considerably in recent years, for
which NICE should be commended. We do believe that despite these
changes, there remain a number of areas where further improvements
should be made. These include:
EARLY ENGAGEMENT
WITH PHARMACEUTICAL
COMPANIES
16. Unlike the regulatory authorities, NICE
does not engage with pharmaceutical companies in early dialogue
concerning the data needed to conduct a NICE appraisal. Without
this dialogue, there remains a risk that NICE will reject a medicine
because the pharmaceutical company did not collect data required
by NICE.
17. We welcome the indication from NICE
that it may be willing to engage in early discussions with pharmaceutical
companies to clarify future data needs in the event of a NICE
evaluation. We strongly urge NICE to implement this change in
order to help reduce the likelihood of negative recommendations
due to different expectations of required data. It should also
lead in return to faster decision-making and a more timely issue
of appraisals.
18. NICE needs to recognise that it may
not always be possible to conduct clinical trials to meet their
specific information requests, especially before and around the
time the medicine is licensed. NICE, therefore, needs to adopt
a pragmatic approach to assessing new medicines, and not unduly
punish a pharmaceutical company if these data are not forthcoming.
19. Given the limited scope of clinical
trials, the real value of a medicine to the NHS can only be confirmed
after launch following sufficient and appropriate use in a real
world setting. There is clearly a trade-off between the need for
NICE to provide early advice on new medicines, and our ability
to provide the type of data required to make such decisions. We
believe that earlier engagement between NICE, pharmaceutical companies
and other key stakeholders such as patients, carers and clinicians,
would enable a more informed dialogue about the optimal time to
conduct any appraisal given that the evidence base for new medicines
evolves over time.
Recommendation 2
PHARMACEUTICAL COMPANY
PARTICIPATION IN
APPRAISAL COMMITTEE
MEETINGS
20. Pharmaceutical companies are currently
the only stakeholder group not represented at appraisal committee
hearings, despite knowing most about the medicine under review.
We believe this is fundamentally wrong and increases the chances
of arbitrary decision making by NICE. Addressing this shortcoming
would also have a number of practical benefits, including quicker
responses to any questions or uncertainties about submitted data,
and reducing the likelihood of decisions going to appeal as a
result of factual errors and omissions.
21. We note that other HTA agencies, including
the All Wales Medicines Strategy Group, have managed to successfully
include pharmaceutical companies in their meetings and would request
NICE consider this option.
Recommendation 3
TRANSPARENCY
22. Pfizer believes the NICE appraisal process
should be fully transparent. We note that other HTA agencies,
including the All Wales Medicines Strategy Group, hold their hearings
in public. We believe NICE appraisal committee hearings should
adopt this approach.
23. We remain particularly concerned that
NICE does not make available to stakeholders its cost effectiveness
calculations in a format that enable independent audit. This is
unreasonable and in contrast to the requirement of pharmaceutical
companies to provide all of their calculations with unlocked,
fully operational versions of the models that are developed as
part of their submission.
Recommendation 4
THE APPEAL
PROCESS
24. The current NICE appeal process focuses
almost exclusively on whether the appraisal process has been followed
correctly. It provides insufficient opportunity to review whether
the appraisal decision is fair and balanced in light of the available
evidence. The range of data chosen to be included, and the fundamental
assumptions in the cost-effectiveness model are not subject to
appeal, yet these are likely to be at the heart of flawed guidance.
The consequences of flawed guidance can be profound for patients
and their carers. As such the development of a fair appeal process,
where the evidence reviewed and value judgements adopted by the
panel can be critically examined, is long overdue.
25. Failings of the current appeal process
include:
The definition of perversity adopted
by NICE serves no practical use as no guidance could realistically
meet the NICE definition of "perverse".
The current appeal process is conducted
by NICE itself with no external consultation as to its form or
judgements. Essentially, NICE members act as judge and jury on
their own decisions.
The level of input from affected
stakeholders appears to be arbitrary.
Certain groups of stakeholders such
as patients may be excluded by the complexity of the process.
Recommendation 5
METHODOLOGICAL ISSUES
26. Pfizer remains concerned that the methodological
approaches adopted by NICE systematically underestimate the value
of medicines to patients and the NHS. This is primarily due to
the failure of currently available tools to capture the full value
of medicines to patients along with the systematic exclusion of
important costs and benefits for appraisals. Pfizer is also concerned
that NICE fails to publicly recognise the wide range of plausible
cost-effectiveness estimates that exist in many appraisals and
instead, places undue emphasis on individual estimates.
LIMITATIONS OF
EXISTING TOOLS
FOR ASSESSING
HEALTH GAIN
27. NICE has adopted the quality-adjusted
life year (QALY) as the standard basis for assessing the value
of medicines. It is widely acknowledged that the QALY has very
significant limitations and does not produce reliable estimates
of health gain (McDonough, 2007). For example, NICE recommends
the use of a generic tool for assessing health gain, the EQ-5D,
for incorporation in QALY analyses. This instrument is simplistic
and relatively insensitive to important changes in quality of
life that are important to patients (Krahn-Murray et al, 2007).
28. In practice, the tendency to under-report
the impact of a medicine on a patient's quality of life actively
disadvantages those medicines where the benefit is in improving
quality of life rather than extending life expectancy, such as
medicines for pain relief and neurological conditions. By implications,
patients with chronic conditions and elderly patients are most
likely to be disadvantaged (Harris, 2005).
Recommendations 6 and 7
FAILURE TO
INCLUDE THE
FULL COST
AND SAVINGS
ATTRIBUTABLE TO
MEDICINES FROM
A TOTAL
HEALTHCARE SYSTEM
PERSPECTIVE
29. NICE currently only includes the financial
impact of medicines on NHS and social services budgets. It excludes
the impact on social security payments and costs borne by patients
and carers. For example, residential care costs borne by patients
were excluded in the appraisal of medicines for the treatment
of Alzheimer's disease, which has the effect of systematically
under-estimating the value of these medicines. In addition, focusing
on new technologies and medicines in isolation risks ignoring
the potential implications for increasing costs elsewhere in the
system.
30. Pfizer believes NICE appraisals should
reflect the full value of medicines to UK society, rather than
the NHS alone. An approach would be to focus on "episodes
of care" as a way to recognise the full cost and value of
an intervention, the overall patient outcome, and the corresponding
costs and benefits incurred across the healthcare system. By expanding
the perspective from one of evaluation in isolation to a broader
systemic look, it is possible to better integrate the cost and
value of medicines and focus the comparison of all treatment options
on their ability to affect overall outcomes. Hence, NICE needs
to review how the perspective taken in its cost effectiveness
analysis can be broadened to allow additional relevant costs and
benefits delivered outside the NHS to be formally taken into account.
Recommendation 8
OVER-RELIANCE
ON ECONOMIC
ASSESSMENTS
31. Pfizer is concerned that NICE does not
fully respect the limitations of current economic analyses methodologies
and resulting imprecision of these assessments. Economic modelling
often results in a wide range of plausible cost-effectiveness
estimates, depending on which data and assumptions are used. Despite
this uncertainty NICE appraisal committees appear to place undue
weight on the certainty of economic analyses when developing guidance.
32. The complexity of evaluation methods
employed by NICE have increased considerably in recent years.
However, despite adding the appearance of advanced science, these
methods do not obviate the need for pragmatism in handling data,
particularly those derived from recently launched products.
33. While economic assessments can legitimately
generate a wide range of plausible value for money estimates,
these should be seen as contributing to the decision making. Pfizer
believes NICE places undue emphasis on a single result within
this range and does not adequately recognise the high degree of
variability of these results.
Recommendation 9
FUTURE ROLE
OF HTA
34. Despite the progress NICE has made since
1999, there remain a number of important areas where NICE reform
is required to ensure that it properly fulfils its current role.
However, even if these issues are addressed, the fundamental limitations
of HTA will remainit provides only one of a number of perspectives
on the value of health technologies, it is conducted at a distance
from the vital conversations between patients and their doctors,
and it cannot foresee how medical advances will develop in practice.
35. Sir David Cooksey's report on medical
research in the UK and the Office of Fair Trading's market study
into the Pharmaceutical Pricing and Regulation Scheme (PPRS) suggest
far wider roles for HTA in priority setting and pricing. The range
of problems with these ideas are out of the scope of the Committee's
current inquiry, but the suggestions are worth noting since they
reflect an over-enthusiasm for what can be achieved by bodies
like NICE. We have advocated greater pragmatism and more realistic
expectations throughout this submission; this applies with even
greater force to any suggestions about extending NICE's remit
into these areas.
36. Pfizer notes that the current focus
of NICE activities accounts for a relatively small proportion
of NHS activity and expenditure. If NICE is truly to realise its
role in achieving a better use of NHS resources, then it needs
actively to consider broadening its current assessments beyond
a narrow subset of medicines and other technologies. One possibility
would be to look more broadly at the effectiveness and efficiency
of the NHS and how it delivers care.
