RECOMMENDATIONS

  1.  Incentives need to re-aligned to encourage innovation in areas of public health need (eg newer antibiotics) rather than in areas of consumer want and company profit (eg anti-ageing and lifestyle).

  2.  Any and all clinical RCTs involving a new product should be registered with a central agency. Failure to register an RCT prior to it starting would rule its findings inadmissible as evidence in a subsequent licensing or funding application.

  3.  Marketing of products under the guise of post marketing phase 4 research should be much more closely scrutinised by ethics committees as an explicit part of their brief.

  4.  Trials that are industry-funded and which have not gone through an independent peer review process should have independent and rigorous scientific scrutiny to be judged ethically sound.

  5.  Direct to consumer advertising of prescription medicines should continue to be banned and regulation of disease awareness promotion strengthened and enforced.

  6.  Funding should be provided for an independent consumer medicine and health information service free of commercial interest.

  7.  Rational use of medicines should be promoted though provision of high quality, balanced and independent information coupled with feedback to prescribers on utilisation and be matched with meaningful incentives to change behaviour.

  8.  Provision of free samples by pharmaceutical companies should be banned and instead a mechanism provided for prescribers to provide a short trial courses of medicines.

  9.  Funding of licensing bodies should not be directly linked to the number of user pays applications in order to minimise perverse incentives.

  10.  The organisation charged with determining medicine subsidisation from public funds needs to be separated from political and industry influence.

  11.  Conflicting and competing interests of members of these committees should be made more transparent and explicit rules to ensure independence.

  12.  Licensing criteria should be strengthened with consideration of rigorous criteria of fast track licensing, explicit consideration of added therapeutic value in licensing and subsidisation decisions and facilitation of generic introduction.

  13.  Drug safety should be centrally managed and preferably at arms length from the licensing body. A more robust system for pharmaco-vigilance needs to be developed which includes facilitation of a process for patient self-report.

BACKGROUND

  1.  The influence of the pharmaceutical industry on health systems occurs at multiple levels. Over recent years this influence has become increasingly pervasive and has seen a trend to the "pharmaceuticalisation" of health in the developed world. These influences act in the following broad areas:

Licensing

  2.  Current user pays arrangements in many developed countries mean that the pharmaceutical industry is effectively the main funder and therefore the "client" of licensing agencies. Requirements for licensing do not encourage balanced disclosure of research allowing proper assessment of safety and efficacy.

Direct to doctor promotion

  3.  This is very effective at influencing prescriber behaviour and increasing sales. This promotional activity includes visits, gifts and other inducements, subsidisation of conference attendance, free samples etc.

Education

  4.  Pharmaceutical companies provide significant funds for sponsorship and have undue influence on the content of continuing education for prescribers. This takes the form of meeting sponsorship, the provision of "free lunches" through to initiation of education meetings with "expert speakers" discussing the benefits of company products.

Direct to patient promotion

  5.  This also takes many forms and in addition to brand advertising includes disease awareness advertising, thinly disguised brand advertising, funding of disease specific consumer groups, patient education and sophisticated campaigns run by public relations companies. It also includes high profile media coverage of "important breakthrough treatments" or "diseases" with "patients" and interviews with company sponsored "experts".

Research

  6.  Pharmaceutical companies are a major funding source for research. This creates conflicts of interest for investigators, skewing of research towards pharmaceutical treatments and publication bias resulting in a relative decrease in research into non-pharmaceutical and preventative treatments.

DRUG INNOVATION

  7.  True innovations in pharmaceutical development do occur. However, they are the exception rather than the rule.

  8.  It is not well understood that the way in which medicines are developed means there is no reason to suppose that a New Chemical Entity (NCE) will be automatically better than older medicines in the treatments of common chronic conditions. There is good evidence from systematic reviews of the last 20 years of innovation carried out by separate groups in France and Canada that less than 10% of all new products coming to market represent significant advance on currently available therapy.1,2 The pharmaceutical industry has demonstrated a tendency to ignore and hide evidence of non-superiority choosing instead to invest heavily in promoting newer patented "me toos" and lifestyle drugs. This has resulted in prescription choices being driven by commercial rather than by rational prescribing principles. An excellent individual and recent example is the ALLHAT study,3 which examined older and newer treatments for hypertension. It found that the older (and very, very much cheaper) medicines were more effective than newer heavily promoted products at preventing the serious long-term complications of raised blood pressure. This is not just of fiscal concern. Of necessity, long term safety data, (particularly of rare and serious or fatal adverse reactions) cannot be known in the early life of medicines. Over recent decades as many as 13% of new medicines have subsequently been withdrawn or had serious safety caveats imposed on their use.4 Prudent and rational prescribing would dictate that newer agents are used cautiously and conservatively only when it is likely that there will be truly significant added clinical benefit for the patient. Such listings should be monitored by publicly funded and independent pharmaco-vigilance. This rarely happens. Instead newer medicines are often heavily promoted and prescribed with unwarranted enthusiasm and little proactive monitoring.

  9.  The majority of true innovation occurs in state funded and usually small private research institutions. In the opinion of many, pharmaceutical companies have become little more than sophisticated marketing organisations. Despite claims to the contrary, in our opinion it appears that in many instances the high prices of branded patented medicines (largely paid for by the taxpayer) are more likely to sustain expensive marketing and PR campaigns and shareholder profit, than be used for reinvestment into research and development of medicines addressing areas of public health need. Limiting marketing excesses and reducing prices with purchasing strategies such as reference pricing would free up resource for more publicly funded innovative research targeted to areas of health need, and provide incentive for pharmaceutical companies to channel their efforts and profits into development of truly innovative drugs. The public money saved would also pay for robust independent consumer health information to counter the covert (and not so covert) direct to consumer promotion which is gaining momentum in the guise of disease awareness advertising and funding of patient groups.

RECOMMENDATION

  10.  Incentives need to re-aligned to encourage innovation in areas of public health need (eg newer antibiotics) rather than in areas of consumer want and company profit (eg anti-ageing and lifestyle). This will never be achieved using conventional "market forces."

CONDUCT OF MEDICAL RESEARCH

  11.  The majority of clinical trials (and therefore the agenda and often the research design) are now funded by the pharmaceutical industry. They are naturally very adept at designing studies to show their products in a good light. Space precludes fuller detail—many editorials in august journals have highlighted some of the greater excesses. Most forms of scientific half-truth and fraud have been uncovered and published in recent years, and a variety of dubious research practices are cause for ongoing concern. Companies do not use placebo controls or appropriate comparator drugs for their trials—comparator drugs tend to be those least likely to be efficacious and most likely to provoke adverse effects, rather than being the current most effective treatment. Doses chosen for the comparator drug are frequently not equivalent to those of the new drug. These practices result in overestimation of efficacy and safety of the newer drug. Other common practices include non-publication of trial data showing negative effects. Partial publication of data with suppression of negative data, and selection of large numbers of outcomes of dubious clinical significance which, with a currently accepted "statistical significance" level of p=0.05, results in at least one in 20 showing improved outcomes by chance alone.

  12. One of the most flagrant lawful abuses of the scientific method relates to the selective minimum evidence accepted as evidence of efficacy by licensing authorities. Consider a company with a new product (perhaps an antidepressant) which it wishes to license. It commissions several trials, only two of which show any statistically significant efficacy against placebo, indeed one or two actually show the drug may have no effect or even negative effects. Only the two positive trials are put forward for publication and for subsequent proof of efficacy. In this way a product which may have almost no efficacy gains a license. With heavy promotion it may even become a blockbuster!

RECOMMENDATIONS

  13.  Any and all clinical RCTs involving a new product should be registered with a central agency (as indeed they already are locally to obtain ethical consent). Failure to register an RCT prior to it starting would rule its findings inadmissible as evidence in a subsequent licensing or funding application.

  One of the easiest ways this could be achieved would be through ethical committees. Data from all registered trials, even those that were either not completed or remain unpublished, would have to be submitted (in a predetermined format) at the time of any licensing application, together with a statement signed by each of the investigators explaining why any studies were abandoned or remain unpublished. This process should not slow down the normal processing of applications, which already take several months to complete. The stakes are high—blocking the licensing of a single ineffective drug could save taxpayers hundreds of millions of pounds/dollars. A model for such a global clinical trial's register is already available in the Cochrane Collaboration trials register.

  14. Marketing of products under the guise of post marketing phase 4 research should be much more closely scrutinised by ethics committees as an explicit part of their brief.

  "Studies" which are no more than marketing exercises for newer "me-too" drugs should not receive ethics approval. Information sheets in pharmaceutical trials should include details of the amount of money the investigators will receive per patient enrolled and/or donations to their research trust funds and "unrestricted education grants".

  15.  Those trials that are industry funded and which have not gone through an independent peer review process (which public grant funded research bodies use) should have independent and rigorous scientific scrutiny to be judged ethically sound.

  Many of these poor quality studies offer little hope of producing useful new knowledge and are in fact no more than cheap promotional exercises for companies and money gathering exercises for the multitude of investigators. Adequately funded and independent pharmaco-vigilance would provide better data at less cost.

THE PROVISION OF DRUG INFORMATION AND PROMOTION, PROFESSIONAL AND PATIENT EDUCATION

Drug information for consumers

  16.  There is intense pressure to allow direct to consumer communication or advertising by pharmaceutical companies under the guise of "information". The concept of "public—private partnerships which superficially appear attractive, carry very real risks and provide further opportunities for industry capture. Undoubtedly industry will claim that direct to consumer disease awareness promotion is both educational and useful. However, there is no demonstrable benefit for population health and there are potential harms. There is no doubt that disease awareness promotion results in increased use of particular products in the same way as branded DTCA. For the reasons outlined above (see innovations section) the heavy promotion of products still under patent is least likely to result in cost effective health gains. Allowing advertising by permissive legislation, lack of enforcement or (as in the case of the US and NZ) by default, constitutes a public health intervention. As with any public health intervention, there should be evidence that benefits outweigh harms before implementation. We have argued that advertising of prescription medicines directly to the public is of net harm to the public health. The evidence for this is clearly detailed in our report.

  17.  Non-enforcement of legislation by governments, as a soft way of managing the pressure from industry, is widespread—this occurs in the USA Canada and Australia. A government's failure to enforce a ban of advertising by allowing loopholes to permit advertising when a conscious decision has been made that DTCA is of net harm is arguably inconsistent with democratic principles. It is unclear whether this is deliberate policy to encourage industry or whether it represents an inability or unwillingness to take on the pharmaceutical industry in costly and time consuming legal battles.

  18.  Our report (and update) on direct to consumer advertising of prescription medicines in New Zealand has already been made available to the inquiry. The main points to note regarding regulation are that the New Zealand experience shows that complaint driven self regulation of either brand or disease awareness DTCA does not work. If the public is not to be misled, technical (ie scientific) pre-vetting for accuracy and fair balance is essential together with proactive monitoring. Central regulation is not working in the US as it is reported that the FDA have been instructed adopt a liberal attitude to enforcement by the current administration who have been extensively and effectively lobbied by industry.

Changes in Medicine Status to "Over the Counter" (OTC)

  19.  The licensing for provision of some prescription drugs for sale "Over the Counter" has implications for advertising in the UK. If a medicine is available OTC it can then be advertised. It will not take long for consumers to realise that it can be obtained more cheaply on prescription and for the pressure on general practitioners to prescribe to begin. This process may already have begun in the UK following the move of statins to OTC status. There is evidence from the US and New Zealand that GPs prescribe drugs they would not otherwise choose as a result of patient demand driven by advertising. This is not surprising given the "patient centred" model promoted as best practice for doctor patient decision making. Commercial drivers should not be allowed to intrude on this important therapeutic alliance.

RECOMMENDATIONS

  20.  That direct to consumer advertising of prescription medicines should continue to be banned and regulations around disease awareness should be strengthened and enforced.

  21.  Funding should be provided for independent medicine and health information service free of commercial interest.

Drug information for prescribers

  22.  The rules on promotion and sampling to physicians are regularly broken and it is time once again to revisit the relationship between the medical profession and the pharmaceutical industry. This promotion takes many forms; visits, inducements, gifts, funding for conference attendance, travel and provision of free samples. The influence of industry on research and medical education at all levels is very significant and ultimately driven by the need to increase sales of individual products. Despite what individual doctors feel about the influence of industry on their practice, there is no doubt that as a group, prescriber's clinical practice is influenced by this promotional activity. To some extent this situation has arisen as the industry had picked up the shortfall from reduced central funding for both research and education (particularly continuing medical education). The irony is that allowing or indeed encouraging this influence in the end costs the taxpayer more than appropriately funding these activities centrally.

RECOMMENDATIONS

  23.  The keys to rational use of medicines are threefold. The provision of high quality, balanced and independent information coupled with feedback to prescribers on utilisation must be matched with meaningful incentives to change behaviour. There is research showing these are effective ways of promoting rational prescribing. The most appropriate incentive in our view is to involve prescribers in budget management with the autonomy and ability to use savings to improve patient care locally.

  24.  Provision of free samples by pharmaceutical companies should be banned and instead a mechanism provided for prescribers to provide a short trial course for patients of any licensed medication for a chronic condition.

REGULATORY REVIEW OF DRUG SAFETY AND EFFICACY

  25.  Many countries have adopted a user (manufacturer) pays approach to licensing. This leads to a system with processes and importantly attitudes that accommodate industry as the principal client, rather than acting principally as servants of the public. Funding of licensing bodies should not be directly linked to the number of user pays applications in order to minimise perverse incentives.

  26.  Conflicting and competing interests of members of licensing committees should be made more transparent and explicit rules to ensure independence.

  27.  New drugs carry added risks and criteria for fast track licensing need to be rigorous and only implemented in unusual circumstances—for example a vaccine in an outbreak situation or where there is urgent and clear health benefit likely to accrue to a large number of users.

  28.  Licensing of new drugs should include consideration of the ability of a manufacturer to provide evidence of clinically significant added therapeutic value over existing therapies. This would minimise the money wasted on large numbers of heavily promoted "me too" products offering little if any health gain at increased cost.

  29.  Licensing of generic drugs should be facilitated. Loopholes, which allow extension of patents ("evergreening"), are a significant barrier to generic introduction.

  30.  The same comments apply to decisions around the state subsidisation of new drugs. The organisation charged with determining medicine subsidisation from public funds needs to be separated from political and industry influence. In this way politicians are provided with some insulation from industry when decisions are not commercially favourable.

  31.  Recent examples demonstrate that the pharmaceutical industry cannot be relied on to responsibly report safety concerns in a timely manner. Drug safety should be centrally managed and preferably at arms length from the licensing body. A more robust system for pharmaco-vigilance needs to be developed. This should include the facilitation of patient self-report, which is likely to be the most effective early warning system of problems.

RECOMMENDATIONS

  32.  Funding of licensing bodies should not be directly linked to the number of user pays applications in order to minimise perverse incentives.

  33.  The organisation charged with determining medicine subsidisation from public funds needs to be separated from political and industry influence.

  34.  Conflicting and competing interests of members of these committees should be made more transparent and explicit rules to ensure independence.

  35.  Licensing criteria should be strengthened with consideration of rigorous criteria of fast track licensing, explicit consideration of added therapeutic value in licensing and subsidisation decisions and facilitation of generic introduction.

  36.  Drug safety should be centrally managed and preferably at arms length from the licensing body. A more robust system for pharmaco-vigilance needs to be developed which includes facilitation of a process for patient self-report.

PRODUCT EVALUATION, INCLUDING ASSESSMENTS OF VALUE FOR MONEY

  37.  We suggest the committee look closely at the functioning and effectiveness of the PBS in Australia and PHARMAC in New Zealand. Value for money remains largely subjective. Pharmacoeconomics is a young and still very imprecise science. Different economists can and do make very different assumptions and predictions on the same data sets. Many of the variables, particularly opportunity costs, cannot be easily quantified. In our view there is no obvious reason why the costs of medicines should increase any more than general inflation. Compare the price of innovation in the computer industry where with time we expect more power, more memory and more data storage at a cheaper price. The prices demanded (and paid) for many new medicines cannot be justified on the basis of value added over existing products, nor on the argument of research and development costs. In many cases they do not represent good value for money. Prioritisation frameworks for organisations which evaluate products (eg NICE) should include public health needs in their prioritisation for reviews to guard against a tendency to use these evaluations solely as a counter to industry skewing the focus towards new chemical entities.

RECOMMENDATIONS

  38.  We suggest the committee look closely at the functioning and effectiveness of the PBS in Australia and PHARMAC in New Zealand.

  39.  Prioritisation frameworks for organisations that evaluate products (eg NICE) should include public health needs.

CONCLUSION

  40.  There is intense pressure on politicians and policy makers in all countries from powerful pharmaceutical lobbyists. The common themes of this lobbying include:

    —  decreasing times to licensing;

    —  more liberal rules on advertising directly to consumers;

    —  increase in patent protection times;

    —  increased barriers to introduction of cheaper generic drugs through intellectual property and patent protection; and

    —  limit access to data used to license drugs on the grounds of "commercial sensitivity".

  41.  Drug company arguments for special commercial consideration in these areas include the importance of their industry and the high costs of research and development. There is no other industry that receives commercial protection at such a high level. Third party insurers (often the state) largely underwrite their profits. In general the industry have not shown the extra responsibility that would be expected to be associated with such a privileged position. Indeed some would say they have abused this privilege. Arguments, which promote high research and development costs as a threat to viability of the industry, are not sustained by evidence. The pharmaceutical industry globally is currently among the most profitable. This does not suggest they are struggling with R&D costs or that additional concessions should be considered.

  42.  Medicines generally are of enormous value to the health of populations when used appropriately. The pharmaceutical industry will understandably push the boundaries as far as regulatory frameworks allow in order to maximise profits for their shareholders. Many have observed that the pendulum has swung too far in favour of the pharmaceutical industry. Governments and regulatory authorities have a responsibility to enhance and protect the health of the public, ensuring safe and effective medicines are available whilst using taxpayers money wisely. To achieve these aims incentives must be aligned to ensure that the pharmaceutical industry serves the population and not the other way around.
