Evidence submitted by Wyeth Pharmaceutical
(NICE 88)
Wyeth is a global pharmaceutical company dedicated
to the discovery, development, manufacturer and sale of human
and animal pharmaceutical products. Wyeth is the 7th largest pharmaceutical
company based on sales in the UK.[156]
Four of Wyeth's products are the subject of nine multiple health
technology appraisals (MTAs).
As a member of the Association of the British
Pharmaceutical Industry (ABPI), Wyeth supports and endorses the
submission to the Health Select Committee made by the Association.
In addition, Wyeth welcomes the opportunity to submit evidence
of its experience to inform the committee's inquiry into aspects
of the work of the National Institute of Health and Clinical Excellence
(NICE).
1. Executive Summary
In this submission Wyeth identifies a number
of factors relating to; the challenge of NICE's decisions, NICE's
evaluation process, the speed of publishing guidance, the appeal
system and the implementation of guidance. To address the issues
raised, Wyeth recommends:
A greater consideration of factors
other than cost per QALY in decision making; eg acceptability,
appropriateness, preference and innovativeness of the technology,
degree of clinical need, consideration of national clinical priorities
and a broader (societal) view of the costs and benefits associated
with the technology.
Enabling NICE to commission work
directly with the academic assessment groups thus giving them
greater control over the quality of work carried out.
Reciprocal access to economic models
between the Assessment Group and contributing Stakeholders.
Manufacturers should have the same
opportunity to attend Appraisal Committee meetings as nominated
members from other stakeholders.
Access to the ERG report should be
given to stakeholders prior to the Appraisal Committee meeting.
There should be consultation over
the Costing Templates and Costing Report.
In the event of little or no change
to the FAD post appeal, the Guidance Executive should make the
necessary changes and publish the guidance in accordance with
section 4.6.9 of the NICE Guide to the Technology Appraisal Process.
An independent Appeal Committee,
without NICE board members, hears appeals.
The opportunity, at appeal, for stakeholders
to challenge the clinical rationale and the quality of the evidence
upon which the recommendations are made.
Appropriate audit/measure of the
implementation of NICE guidance and guidelines.
Incentives for the implementation
of guidance and guidelines.
That subsequent guidance is placed
in context with existing guidance.
Mandatory funding for clinical guidelines.
2. WHY
NICE'S DECISIONS
ARE INCREASINGLY
BEING CHALLENGED
2.1 NICE's decisions are becoming increasingly
reliant on the estimated cost effectiveness, expressed as cost
per quality adjusted life year (QALY) gained, as the sole determinant
of whether or not to recommend a therapy for use within the NHS.
The cost per QALY gained frequently does not accord with both
patients' and health care professionals' experience of the value
of the therapy being appraised. For example the cost per QALY
fails to account for the impact of disease and its treatment on
carers and the immediate family of the patient.
2.2 Cost per QALY also fails to account
for the broader societal benefits derived from treatment such
as ability to continue/return to work; with associated reduction
in unemployment and/or disability benefits and increase in tax
revenue from the individual maintaining or restarting work. This
disparity in value is greatest in early onset, chronic, degenerative
conditions such as Ankylosing Spondylitis (AS). Despite acknowledging
that up to 30% of sufferers are unable to work, the recent Appraisal
Consultation Document (ACD) for the use of TNF inhibitors in the
treatment of AS, seeks to restrict the long-term use of these
agents to the 6% of patients whom NICE consider achieve a cost
per QALY of less than £20,000.
2.3 There is variability in the quality
and consistency of the Assessment Reports, commissioned on NICE's
behalf from various academic centres within the UK and upon which
the Appraisal Committee's base their recommendations. Our concerns
relate to the adequacy with which the resultant Assessment Reports
address the scope of the appraisals, the appropriateness of the
structure and inputs to the economic models, the extent to which
comments from stakeholders are addressed by the assessment groups
and the handling of uncertainty with respect to the cost effectiveness
analyses. Failure to address these issues during the appraisal
process increases the likelihood of the final decision being challenged.
2.4 The above concerns may be exacerbated
in part by the system under which Assessment Groups are contracted
to produce the reports that inform NICE decision-making. There
are no direct agreements between NICE and individual Assessment
Groups (with the exception of the Decision Support Unit). The
Department of Health contracts with the umbrella organisation,
the National Collaborating Centre for Health Technology Assessment,
which is responsible for managing the contracts with individual
Assessment Groups. The Institute thus has no direct contractual
relationship with the Assessment Groups, although it is their
ultimate customer. As such, NICE has limited ability to require
and ensure that the reports produced by the Assessment Groups
are fit for purpose.
2.5 Wyeth are appealing the recent Final
Appraisal Determination (FAD) for use of TNF inhibitors in the
treatment of Rheumatoid Arthritis (RA). One of the aspects of
this appeal relates to the Assessment Report failing to evaluate
the earlier use of these agents despite the scope indicating that
the appraisal should attempt to identify the stage in the pathway
of care where these agents should be used. Another aspect of Wyeth's
appeal relates to the failure of the assessment group to carry
out the analysis of uncertainty defined in NICE's Guide to the
Methods of Technology Appraisal.
2.6 It is often difficult to determine why
estimates of cost effectiveness derived by the assessment groups
differ from those generated by the manufacturers and other stakeholders.
Whilst the assessment groups have full access to the economic
models produced by the manufacturers the assessment groups maintain
their models in confidence in order to protect the intellectual
property rights to their work. In the event that NICE negotiates
release of the assessment groups' models they are "locked"
to prevent stakeholders from re-running them, which thwarts stakeholders
attempts to understand how they work. Given stakeholders concerns
over the quality of the assessment groups' work, failure to fully
disclose how their estimates of cost-effectiveness are derived
further increases the likelihood of the final decision being challenged.
2.7 Thus far despite concerns raised by
both manufacturers and healthcare professionals over the construct
of the assessment group's model for the appraisal of TNF inhibitors
in the treatment of AS, neither the assessment group or NICE have
attempted to address these issues.
2.8 In conclusion, differences in the perceived
value derived from the technologies being appraised and a lack
of transparency regarding how decisions are reached results in
an increasing number of challenges from patient, healthcare professional
and manufacturer stakeholders.
2.9 Wyeth recommend:
a greater consideration of factors
other than cost per QALY in decision making; eg acceptability,
appropriateness, preference and innovativeness of the technology,
degree of clinical need, consideration of national clinical priorities
and a broader (societal) view of the costs and benefits associated
with the technology;
enabling NICE to commission work
directly with the academic assessment groups thus giving them
greater control over the quality of work carried out; and
reciprocal access to economic models
between the Assessment Group and contributing Stakeholders.
3. WHETHER
PUBLIC CONFIDENCE
IN THE
INSTITUTE IS
WANING, AND
IF SO
WHY
3.1 The public's perception of NICE is informed
to a large extent by the media coverage of its activities which
focus on the frequent challenges to its decisions by patients,
healthcare professionals and manufacturers. The media coverage
is associated with the failure of the decisions taken by NICE
to promote the faster uptake of innovative medicines and a failure
to prevent postcode prescribing.
4. NICE'S
EVALUATION PROCESS,
AND WHETHER
ANY PARTICULAR
GROUPS ARE
DISADVANTAGED BY
THE PROCESS
4.1 Manufacturers, having developed and
licensed the technologies, provide much of the evidence being
appraised and yet they are excluded from the initial Appraisal
Committee meeting when the evidence base is first discussed prior
to the committee drafting its initial recommendations. This denies
the Appraisal Committee the opportunity to have addressed any
outstanding questions that can only be answered by those directly
involved in generating the data. Enabling the manufacturer to
hear the discussions would also increase the transparency of the
subsequent decision-making and likely lead to a reduction in appeals
brought about due to a failure to understand how decisions have
been reached. Manufacturers are singularly disadvantaged as patients
and healthcare professional organisations are asked to nominate
experts who are invited to submit a personal view of the technology
and to attend the first Appraisal Committee meeting.
4.2 Within the newer Single Technology Appraisal
(STA) process it is the critique of the manufacturers submission,
performed by an academic Evidence Review Group (ERG) that is provided
to the Appraisal Committee to inform their decision-making. As
the report is not made available prior to the Appraisal Committee
meeting and the manufacturer is not invited to attend the meeting,
despite generating the original submission, the manufacturer remains
unaware of the content of the final report until after the ACD
or FAD has been issued. The lack of opportunity to correct any
factual errors contained within the ERG's report clearly disadvantages
the manufacturer and may lead to subsequent delays as these errors
are addressed later in the process.
4.3 The "Implications for the NHS"
section of draft guidance has been replaced by reference to implementation
tools, in particular a "Costing Template and Costing Report",
which are not made available until after final guidance is issued.
NICE invite stakeholders to comment on whether they consider that
the preliminary views on the resource impact and implications
for the NHS are appropriate. However the failure to release draft
copies of these tools along with the ACD prevent stakeholders
from commenting on this important aspect of the draft guidance.
NICE have announced the intention to consult with stakeholders
over the Costing Template and Report, however these tools have
not been released with either the ACD or FAD for the previously
mentioned AS and RA appraisals respectively.
4.4 The variability of the quality of Assessment
Reports has resulted in the need to issue addenda to correct errors
in estimates of effectiveness, costs, utilities and additional
benefits gained. In the event that the Appraisal Committee is
not happy to make a recommendation on the strength of the evidence
contained within the Assessment Report NICE have undertaken, or
commissioned the Decision Support Unit (DSU) to undertake further
analysis to address deficiencies. This results in delays in publication
of Guidance and, as a consequence, delays in patient access to
the appraised medicines. NICE have recently announced with regret
that they have asked the DSU to undertake further analysis to
inform the aforementioned AS appraisal. As yet NICE have not been
in a position to provide stakeholders with a revised timeline
for publication of guidance.
4.5 Clinical specialists and patient experts
whilst invited to attend the first Appraisal Committee meeting,
often have, insufficient understanding of health economic methodology
and NICE's processes and methods to effectively and fully engage
in the HTA process. In addition, the groups that they represent
often have limited resources, which further reduce their ability
to make effective representations.
4.6 Wyeth recommend:
manufacturers should have the same
opportunity to attend Appraisal Committee meetings as nominated
members of other stakeholders;
access to the ERG report should be
given to stakeholders prior to the Appraisal Committee meeting;
and
there should be consultation over
the Costing Templates and Costing Report.
5. THE
SPEED OF
PUBLISHING GUIDANCE
5.1 Capacity to undertake appraisals, requirements
for additional analyses and appeals to FADs all serve to reduce
the speed with which guidance is published. As an example, despite
advanced notification to the Department of Health of the anticipated
license of etanercept for the treatment of AS in January 2004,
the HTA for this technology is still ongoing. In October 2003,
based on the extent of the burden of illness of AS, the likely
budget impact and the anticipated funding issues, Wyeth requested
that etanercept, along with infliximab, be included in the 8th
wave of products referred to the Institute for appraisal. The
topic was subsequently referred in the 9th wave with guidance
anticipated in February 2006. NICE delayed the appraisal by 10
months to include the third TNF inhibitor adalimumab. There was
a three-week delay in release of the Assessment Report, which
was finally issued in June 2006 and a four-month delay in release
of the draft guidance (ACD), which was finally released in December
2006. The delay in generation of the draft guidance was due to
a request from the Appraisal Committee to the Assessment group
for additional sub-group analysis. At this stage final guidance
was anticipated in June 2007. However due to the repeated concerns
expressed by all stakeholders as to the structure and inputs to
the Assessment Group's model, NICE have asked the Decision Support
Unit to conduct further analysis to inform generation of the FAD.
At the time of this submission the extent of this further delay
is not known.
5.2 Until such time as NICE publish its
final recommendation on the use of TNF ( inhibitors for the treatment
of AS, funding is restricted to the few individuals for whom treatment
can be negotiated on a case by case basis. In a recent survey
of its consultant membership, the British Society of Rheumatology
(BSR) identified that one third of respondents have no access
to TNF inhibitors to treat patients with AS.[157]
Only 25% of respondents reported the ability to prescribe in accordance
with BSR guidelines. Clearly the delay in publication of NICE
guidance is having a significant negative impact on patient access
to these innovative treatments.
5.3 Despite the vast majority of the appeal
points being dismissed, and those upheld resulting in no substantiate
change to the recommendations, the FADs for the Psoriasis and
Psoriatic Arthritis appraisals were returned to the Appraisal
Committee to be amended and reissued. This resulted in a lapsed
time of 5-6 months from the appeal hearing to final publication
of the guidance.
5.4 Wyeth recommend:
in the event of little or no change
to the FAD post appeal the Guidance Executive make the necessary
changes and publish the guidance in accordance with section 4.6.9
of the NICE Guide to the Technology Appraisal Process.
6. THE
APPEAL SYSTEM
6.1 Wyeth share the concerns raised by the
ABPI regarding the deficiencies in the current appeal procedure.
In particular, the role of the Chairman of the Appeals Committee
in the initial scrutiny of appeals and the constitution of the
Appeal Panel result in the lack of an independent review of the
conduct of and decisions reached by the Appraisal Committee. The
initial scrutiny of lodged appeals is intended to ensure that
the appellant has a valid and arguable case. In practice, however,
this review frequently addresses the merits of the appeal also.
Given that the Chairman of the Appeals Committee subsequently
sits on the Appeal Panel such initial scrutiny could prejudice
the appeal. Two or three of the five members of the Appeal Panel,
including the Chairman of the Panel, are members of NICE's own
board. Such board members could be expected to have an inherent
interest in defending the decision reached by the Appraisal Committee,
which again one could argue would be prejudicial to the fair hearing
of the appeal.
6.2 As indicated throughout this submission,
many of the concerns surrounding the NICE appraisal process relate
to the quality of the evidence base upon which decisions are reached
and the scientific merits of those decisions. However current
interpretation of the very restrictive grounds for appeal prevent
either of these aspects being challenged at appeal.
6.3 The criteria for the successful appeal,
made under the ground that the Institute has prepared a FAD that
is perverse in the light of the evidence submitted, is so unrealistically
high as to prevent any substantive review of the recommendations
made.
6.4 Wyeth recommend:
an independent Appeal Committee,
without NICE board members, hears appeals; and
the opportunity, at appeal, for stakeholders
to challenge the clinical rationale and the quality of the evidence
upon which the recommendations are made.
7. THE
IMPLEMENTATION OF
NICE GUIDANCE, BOTH
TECHNOLOGY APPRAISALS
AND CLINICAL
GUIDELINES
7.1 The extent of implementation of both
HTA guidance and clinical guidelines is difficult to determine
as they are not systematically assessed. Whilst the Healthcare
Commission is responsible for assessing the performance of NHS
organisations to ensure they conform to NICE technology appraisals,
this currently consists of the self-assessment of whether an organisation
has a procedure in place to ensure conformity, rather than a measure
of the effectiveness of the procedure.
7.2 From the various assessments of the
implementation of individual health technology appraisals it is
clear that the uptake of recommended therapies can be both slow
and inconsistent across England and Wales. The BSR's survey of
its membership identified that despite a positive NICE recommendation
for the use of TNF inhibitors to treat RA patients published in
2002, 42% of respondents indicated that, four years on, they still
had some form of restriction on the prescribing of these agents
in line with NICE guidance. 70% cited some form of cap on funding
whilst 21% and 9% cited lack of staff or facilities, respectively.
7.3 With the advent of the STA process,
there will be increasingly an MTA and a number of STAs covering
the same patient population, as will be the case in the near future
with TNF inhibitors for the treatment of psoriasis. If MTAs and
STAs do not inter-relate it will be difficult for clinicians to
identify which piece of guidance to follow.
7.4 Wyeth are concerned that the replacement
of HTA guidance, and associated mandatory funding, with clinical
guidelines, for which funding is not mandated, may lead to restrictions
in patient access to these medicines as NHS organisations prioritise
the funding of guidance.
7.5 Wyeth recommend:
appropriate audit/measure of the
implementation of NICE guidance and guidelines;
incentives for the implementation
of guidance and guidelines;
that subsequent guidance is placed
in context with existing guidance; and
mandatory funding for clinical guidelines.
