Beyond health gain:the value of knowing in precision medicine

Value assessment in precision cancer medicine

Towse and Garrison provide a clear picture of the economics of using drugs with companion diagnostics (precision medicine) in the Journal of Cancer Policy. Three main issues arise:

A. Reducing or avoiding the adverse effects associated with treatment (including the medical and nonmedical costs of man-aging them).
B. Reducing or avoiding time delays in selecting the most appropriate intervention
C. Enabling a treatment effective only in a small fraction of the population to be made available or more widely available.

But there are also psychological gains (difficult to estimate) related to the value of knowing:

1. Reduction in uncertainty reflecting the idea that a companion diagnostic, by increasing the certainty of a patient’s response to a medicine—would be more valuable to individual patients and hence they (or their payer) would be willing to pay more for the combination. Furthermore, as noted above, at the population level, greater certainty could lead to greater uptake and improved compliance.
2. The value of hope is the notion that in some circumstancesindividuals become risk-seekers in the sense that they would be willing to pay more for access to a technology with a long tail indicating that some patients have a much longer survival time than current therapy, even though the average life expectancy may be no greater, or even less, than standard therapy.
3. Real option value for which the best example is that if  a treatment can extend life, this opens up possibilities for individ-uals to benefit from future advances in medicine. Hence, they(or their payer) should be willing to pay more than simply theamount they would pay for a gain in life expectancy alone, ascalculated under conventional methods, because it provides the option of benefiting from further treatments.
4. Insurance value is related to the idea that insurance tocover innovations provides peace of mind, not just by protectingagainst catastrophic financial loss but also by protecting fromcatastrophic health loss. The focus is usually only on financial protection, in the form on an Extended Cost-effectiveness Analysis. Lakdawalla et al. point out that greater value comesfrom the reassurance value of knowing of the existence of a treatment, or even of incentives to develop such a treatment.
5. Scientific spillovers arise because the benefit of scientificadvances cannot be entirely appropriated by those making them. Improving knowledge creates opportunities for additional innovation by others. For example, proving that a particular agentworks on a hypothesized pathway in a particular cancer means that the general understanding of that cancer is enhanced and thus further research can explore other pathways in the same cancer. This creates a commons problem with potential underinvestment, implying that patients may wish to reward developerswith higher prices to encourage knowledge generation.

The authors back value based pricing for drugs and companion diagnostics, just at the same time that The New York Times casts some shadows over this option.

Precision medicine: a deep breakthrough in life sciences paradigm

Bioscience - Lost in Translation? How precision medicine closes the innovation gap

It is not so easy to translate knowledge into practice, and this is the case of biosciences into clinical applications. However, recently this trend is accelerating and precision medicine is emerging. A new book gives us the highlights to understand precisely what's going on: Bioscience - Lost in Translation? How precision medicine closes the innovation gap.

Richard Barker (the author of 2030 - The future of medicine) says:

The classic definition of diseases has been in terms of the symptoms they cause and/ or where in the body they appear. This was the best that medicine could do when external observation of the patient was the only or primary means of diagnosing disease. The  powerful new tools of molecular biology are reinterpreting disease in terms of aberrant,
defective, or unbalanced molecular mechanisms at the cellular, organ, or organism level. Molecular level diagnosis becomes a real possibility. Such an approach brings effective therapy immediately closer. Molecular diagnostics can separate diseases with similar symptoms but different underlying causes— and often suggest a different starting point for intervention.

If this is so, what should we do?

The seven changes of mindset and of practice are:
1. Advance the molecular definition of disease and the application of systems biology. We need a more decisive move from a classic definition of diseases— in terms of the symptoms they cause and/ or where in the body they appear— to a definition in terms of aberrant, defective, or unbalanced molecular mechanisms at the cellular level. And we need to marry this with a recognition that singular target- based innovation rarely works: we need a systems biology approach.

2. Partner academia and industry in more collaborative, impact- oriented research. We need to extend the ‘open innovation’ approach in which academia and companies invest together and share IP. We need to define new pre- or non- competitive spaces, especially in work on disease mechanisms and disease models. And we need to provide for new types of links and incentives to break down the barriers between these two worlds. 

3. Move decisively to a more adaptive approach to development, trial and approval design. We need to build on successful experiments in more flexible trial design, development pathways, and regulatory appraisal to a globally accepted adaptive approach. This involves collaborative design of the evidence package needed to secure approval and reimbursement, and greater teamwork through the process. 

4. Create new reward and financing vehicles for leading edge innovation. We need to move from reward systems based purely on unit sales of products, irrespective of outcome, to rewarding innovators for positive outcomes, patient by patient. We also need to design financing mechanisms that bridge between cost- effectiveness and affordability. We must be able to accommodate high- cost precision therapies that offer cures and so generate long- term returns for the system.

5. Engineer tools and systems for faster and better innovation adoption and adherence. We need to move from reliance solely on promotion to doctors and passive patient participation to a disciplined approach to establishing new pathways of care. These will be based on modern behavioural science, clinical decision support, and other digital technologies.

6. Develop an infrastructure for real- world data- driven learning. We now have the opportunity to study in large populations how lifestyle and treatment choices lead
to outcomes, learning from every patient as if in a clinical trial. New analytical tools will empower this.

7. Bring patients into the mainstream of decision- making and engage them  hole heartedly throughout the process. It is time to move from a process and mindset in which patients are regarded as passive subjects for clinical trials and recipients of products and procedures. Their input and engagement needs to be sought along the whole innovation chain: on treatment benefits, acceptable risks, optimal clinical trial design, adherence support, and outcomes.

Highly recommended.

In search of the balance between government and market

THE LIMITS OF THE MARKET: The Pendulum between Government and Market

Thirty years ago I bought a book that was a key reference MARKETS OR GOVERNMENTS : CHOOSING BETWEEN IMPERFECT ALTERNATIVES. The focus was clear, the government should enter when there is a market failure and try to curb it. This was the message and has been the message for many years. Now we know that the approach was too simplistic. If you want to understand an updated approach to the same issue, check the new book by Paul de Grawe, THE LIMITS OF THE MARKET: The Pendulum between Government and Market. A well written and accessible book that helps to remake the arguments with the evidence of the past years. The chapters:

The Great Economic Pendulum
The Limits of Capitalism
External Limits of Capitalism
Internal Limits of Capitalism
The Utopia of Self-Regulation in the Market System
Who can Save the Market System from Destruction?
External Limits of Governments
Internal Limits of Governments
Who is in Charge? Market or Government?
Rise and Fall of Capitalism: Linear or Cyclical?
The Euro is a Threat to the Market System
The World of Piketty
Pendulum Swings between Markets and Governments

At the end of the book there are two issues that concern the author: inequality and the degradation of environment. The need for internation cooperation on taxation is critical for the first issue, and the functioning of democratic institutions for both. His final comment is a call for action:

The Myth of Sisyphus

Sisyphus was a Greek king who felt stronger and wiser than Zeus, and was punished for his hubris. He was sentenced to push a rock up a mountain every day, after which the rock would roll back down each evening. The following day Sisyphus had to start all over again, continuing for eternity. In his essay The Myth of Sisyphus Albert Camus gave an existentialist interpretation of this well-known Greek myth. Camus sees Sisyphus’s punishment as a metaphor for the absurdity of life. How should we deal with this absurdity, he wonders? One option is to commit suicide. Camus rejects this option. Instead he suggests that we should rebel against the absurdity of life by throwing ourselves into it, living intensely, and being creative. The revolutionary hero is the one who despite the absurdity and knowing that his rebellion will eventually achieve nothing, still sets the rock in motion and remains happy. ‘Il faut s’imaginer Sisyphe heureux’ (‘One must imagine Sisyphus happy’), Camus decided.
That is the position I would like to offer as a guiding principle for the end of this book. It will be extraordinarily difficult to prevent future catastrophes. It may even already be too late. (I am at least a little more optimistic than Albert Camus with his Sisyphus interpretation, which is very bleak indeed.) We have a small chance of preventing decline with the reforms I outlined above. But even if that does not work, we are left with the option of doing as Sisyphus did, of starting again each day. It is the only way of giving meaning to our existence. If we do not take action, our grand children will not forgive us for failing to try to save them. That in itself is sufficient motivation to persist.

Transforming the practice of care in the most inefficient and wasteful health system

The Smart-Medicine Solution to the Health-Care Crisis

Eric Topol provides clear insights for a wide range of life sciences issues, and some days ago he insisted once again on the need to reform US health system. Everybody is talking about financing and acces, and he focuses on organization. That's good to hear. I suggest a close look at the WSJ article. Although the scope is US, you'll find many comments that are absolutely useful for our health system (the public and specially the private one).

Our health-care system is uniquely inefficient and wasteful. The more than $3 trillion that we spend each year yields relatively poor health outcomes, compared with other developed countries that spend far less. Providing better health insurance and access can help with these problems, but real progress in containing costs and improving care will require transforming the practice of medicine itself—how we diagnose and treat patients and how patients interact with medical professionals.

And he backs a smart medicine practice:

Smart medicine offers a way out, enabling doctors to develop a precise, high-definition understanding of each person in their care. The key tools are cheaper sensors, simpler and more routine imaging, and regular use of now widely available genetic analysis. As for using all this new data, here too a revolution is under way. 

And the key integrative tool:

At the Scripps Research Institute, we are working with the support of a National Institutes of Health grant and several local partners to develop a comprehensive “health record of the future” for individual patients. It will combine all the usual medical data—from office visits, labs, scans—with data generated by personal sensors, including sleep, physical activity, weight, environment, blood pressure and other relevant medical metrics. All of it will be constantly and seamlessly updated and owned by the individual patient.

Good news (US only):

 Fortunately, serious ventures in smart medicine are well along. My colleagues and I at the Scripps Research Institute are leading the Participant Center of the NIH’s Precision Medicine Initiative, which is currently enrolling one million Americans. Volunteers in the program will be testing many of the new tools I have described here. The recently formed nonprofit Health Transformation Alliance, which includes more than 40 large companies providing health benefits to 6.5 million employees and family members, intends to address the high cost of health care by focusing on, among other things, the sophisticated use of personal data.

I have to say that his position is well grounded, it is not a fascination for technology. The true health reform starts with the practice of medicine. Completely agree.
