This document discusses regulatory inefficiencies surrounding companion diagnostics and laboratory developed tests (LDTs) in the United States. It uses the case study of Genentech's drug MPDL3280A and its companion diagnostic to show that the FDA thoroughly regulates companion diagnostics but provides no oversight of clinical validity for LDTs. This allows multiple competing diagnostic tests to be used without proof of efficacy. The document also compares healthcare systems and technology assessment processes in the US, UK, and France to illustrate decentralized decision making in the US compared to centralized bodies in other countries.

Value-based health care is one of the most pressing topics in health care finance and policy today. Value-based payment structures are widely touted as critical to controlling runaway health care costs, but are often difficult for health care entities to incorporate into their existing infrastructures. Because value-based health care initiatives have bipartisan support, it is likely that these programs will continue to play a major role in both the public and private health insurance systems. As such, there is a pressing need to evaluate the implementation of these initiatives thus far and to discuss the direction that American health care financing will take in the coming years.
To explore this important issue, the Petrie-Flom Center for Health Law Policy, Biotechnology, and Bioethics at Harvard Law School collaborated with Ropes & Gray LLP to host a one-day conference on value-based health care. This event brought together scholars, health law practitioners, and health care entities to evaluate the impact of value-based health care on the American health care system.

What’s Next in US Payor Communications: The Impact of FDA's Proposed Guidance...Nathan White, CPC
The recent enactment of the 21st Century Cures Act has profound immediate and long-term implications for development and communication of HEOR/RWE in the US, particularly in relation to communications with payors about healthcare economic information (HCEI). In January, the FDA released draft guidance for public comment to outline its thinking around communication to payors of HCEI, but there are still unanswered questions to be addressed in the final guidance. Industry will need to quickly establish new policies and procedures to maintain compliance with the new regulations, especially in relation to OPDP submission requirements – a steep transition from a space that has largely been unregulated.

A new study adds further evidence to suggest that opioid prescribing in the U.S. is skewed and concentrated among a few providers. Researchers looked at prescribing patterns in data from an unspecified national private insurer between 2003-2017.
Around 670,000 providers prescribed more than 8 million standard doses of opioid prescriptions — but more than a quarter of these prescriptions were written by only 1% of physicians. And in 2017, these physicians prescribed nearly half of all the dispensed opioids. This small group of doctors also prescribed higher doses than recommended, and for longer durations than guidelines allow.
What’s encouraging, the authors suggest, is that the vast majority of physicians do seem to follow guidelines. Some caveats: The study was based on one company’s data, and didn’t look at medical reasons behind prescriptions.

Seminar on Magnetic levitation and its applicatonRahul Shaw
Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and controlling their forces can levitate an object.
In this process an object is suspended above another with no other support but magnetic fields.
The electromagnetic force is used to counteract the effects of gravitation. But it has also been proved that it is not possible to levitate using static, macroscopic, `classical' electromagnetic fields.
The forces acting on an object in any combination of gravitational, electrostatic, and magnetostatic fields will make the object's position unstable.
The reason a permanent magnet suspended above another magnet is unstable is because the levitated magnet will easily overturn and the force will become attractive. If the levitated magnet is rotated, the gyroscopic forces can prevent the magnet from overturning.
Several possibilities exist to make levitation viable.
It is possible to levitate superconductors and other diamagnetic materials, which magnetise in the opposite sense to a magnetic field in which they are placed.
A superconductor is perfectly diamagnetic which means it expels a magnetic field (Meissner-Ochsenfeld effect). Other diamagnetic materials are commonplace and can also be levitated in a magnetic field if it is strong enough.Diamagnetism is a very weak form of magnetism that is only exhibited in the presence of an external magnetic field.
The induced magnetic moment is very small and in a direction opposite to that of the applied field. When placed between the poles of a strong electromagnet, diamagnetic materials are attracted towards regions where the magnetic field is weak.
Diamagnetism can be used to levitate light pieces of pyrolytic graphite or bismuth above a moderately strong permanent magnet. As water is predominantly diamagnetic, this property has been used to levitate water droplets and even live animals, such as a grasshopper and a frog.
Superconductors are perfect diamagnets and when placed in an external magnetic field expel the field lines from their interiors (better than a diamagnet). The magnet is held at a fixed distance from the superconductor or vice versa. This is the principle in place behind EDS (electrodynamic suspension) maglev trains. The EDS system relies on superconducting magnets.
A maglev is a train, which is suspended in air above the track, and propelled forward using magnetism. Because of the lack of physical contact between the track and vehicle, the only friction is that between the carriages and air. So maglev trains can travel at very high speeds (650 km/h) with reasonable energy consumption and noise levels

Nurse Practitioner Perceptions of a Diabetes Risk Assessment Tool in the Retail Clinic Setting Kristen L. Marjama, JoAnn S. Oliver, and Jennifer Hayes
Diabetes is the seventh leading cause of death in the United States, burdening society with
high costs for treatment and placing increased demand on the health care system (1). According to the 2014 National Diabetes Statistics Report, an estimated 29.1 million people in the United States have diabetes, and 8.1 million of them are undiagnosed (2). The lack of screening for early identification of patients at risk for type 2 diabetes is a significant clin- ical problem. Health care providers (HCPs) need to be aware of the in- creasing diabetes burden and to pri- oritize the screening of patients who may be at risk. Screening for risk can aid in both efforts to prevent the development of diabetes and early management of the disease to reduce complications. Clinical trials have demonstrated that type 2 diabetes can be delayed or prevented through life- style modification or pharmacother- apy for people at increased risk (3).
In order to reduce risk for those at risk of developing diabetes, screen- ing is a priority that will raise patient
awareness. Many patients are not aware of their risk for type 2 dia- betes until they receive a confirmed diagnosis from their HCP. There are numerous health care settings in which screenings can be imple- mented, including but not limited to primary care practices, urgent care centers, hospital emergency depart- ments, and retail health clinics.
Retail clinics are located in retail supermarket and pharmacy chains to provide high-quality, affordable, and easily accessible health care services for communities. A true measure of quality in retail clinics is their degree of adherence to several measures iden- tified in the Healthcare Effectiveness Data and Information Set (4). Services in this type of setting may include treatment of acute episodic conditions, physical examinations, vaccinations, health screenings, and prevention and management of chronic conditions (5). Retail clinics provide services to patients with or without insurance or a primary care “home.†Patients’ visits to a retail clinic afford the opportunity to assess
■IN BRIEF This article describes a study to gain insight into the utility and perceived feasibility of the American Diabetes Association’s Diabetes Risk Test (DRT) implemented by nurse practitioners (NPs) in the retail clinic setting. The DRT is intended for those without a known risk for diabetes. Researchers invited 1,097 NPs working in the retail clinics of a nationwide company to participate voluntarily in an online questionnaire. Of the 248 NPs who sent in complete responses, 114 (46%) indicated that they used the DRT in the clinic. Overall mean responses from these NPs indicated that they perceive the DRT as a feasible tool in the retail cli.

Drug Discovery:
While most compounds will never be approved for use, each one is evaluated to determine its potential value compared to existing therapies, complexity of large scale manufacturing, and other factors.
Preclinical Testing:
Candidate drugs from the discovery stage receive 1 to 3 years of extensive testing to assess safety and show biological activity against a disease.
Chemical tests establish the purity, stability, and shelf life of a compound.
Manufacturing tests determine mass production of the drug.
Pharmaceutical development studies explore dosing, packaging, and formulation of the drug.

2. INTRODUCTION
Personalized medicine as we know it
now is in its infancy relative to the hundreds
of years that traditional medical practices
have been carried out. Figure 1 illustrates
just how new this approach is in the medical
realm. Treatment thus far has been
identification of a general disease or
condition followed by medicating the patient
group with whatever has been found
effective but not necessarily effective for all
patients with the disease or condition. For
decades, we have accepted risks from lethal side effects to a spectrum of results when it comes to
patient outcomes from very effective to not at all. Companion Diagnostics is powerful as it now
permits treatment of subgroups of patient with a certain illness with a stratified approach that has
proven to improve response rates versus traditional medicine. Assuredly, what was once solely a
method of identifying rare genetic diseases has since proven to have a myriad of applications,
from the characterization of tumors to the detection of infectious agents [1][2][3].
The application of this approach towards stratification of patient populations via a
multitude of technologies is, then, useful in the evolution of treatment from the state that it is in
now. With targeted drugs being released monthly, the assay can not only test for the presence of
disease, but can direct medical professionals to better therapy options. Companion diagnostics
Figure 1- Contrast with Traditional Medicine. The
figure shows the breakdown of the general diseased
sub-group population into groups “A” and “B” based
on response to a companion diagnostic. “A” is the
positive response group and is likely to respond to
targeted therapeutic treatment using the stratified
approach. “B” is the negative response group and is
unlikely to respond to targeted therapeutic treatment
using the stratified approach. Source: Sarah K. Byron
et al. Clin Cancer Res 2014;20:1469-1476
3. rely on this concept to co-develop a targeted drug and a diagnostic assay to identify suitable
subjects simultaneously [4].
As interest in personalized medicine in recent years has grown, so has the scientific clout
such that there is no denying that this is the future of treatment for many patients. This is
exemplified in the increase of the number of prominent personalized medicine drugs available
from 2006 to 2011, when the number of available examples ballooned from thirteen to seventy-
two. [5] PricewaterhouseCoopers has predicted personalized medicine will see an eleven percent
increase in the market year to year, with an estimate of $452 billion as the 2015 market value.
Figure 2 seeks to exemplify that the
market for personalized medicine has been
trending positively with regard to specialty
drug approvals from 2005 to 2014, with a
similar trend expected for 2015. In fact,
according to PwC’s Health Research Institute,
the specialty drug Viekira Pak, which is used
in the treatment of Hepatitis C, is estimated to
have three billion dollars in sales in 2016, a
number similar to the estimated revenue from the sale of the generic drug Lipitor for Pfizer. [6]
That is to say, the popular medication for high cholesterol with a target population of around 40
million adults, across the United States alone, is being matched in sales by a drug that has a
target population of about 2.4 million individuals. However, this estimation of sales becomes
more understandable as consideration is given to the fact that Viekira Pak is a curative treatment

4. C drugs started with Boceprevir and Telaprevir, the first of the direct-acting antivirals that were
used clinically in the treatment of Hepatitis C; they illustrate the starting point in the steady
advancement in Hepatitis C treatment effectiveness in recent years. [7]
However, this example also illustrates the biggest pitfalls of personalized medicine with
regard to companion diagnostics. As the market for these treatments expands, the ready
acceptance of these drugs is becoming more and more reliant on dramatic results, such that
developers of specialty drugs receive proper attention. At the same time, regulation of the
necessary co-developed diagnostics by the Food and Drug Administration (FDA) is leagues
ahead of regulation of laboratory developed tests, with regard to evidence development of
efficacy. Even the July 2014 Consumer Health Information Report, released by the FDA,
claimed that because each companion diagnostic test is created as a companion to and is paired
with a specific drug, “the development of both products requires close collaboration between
experts in both FDA’s device center, which evaluates the test to determine whether it may be
cleared or approved, and FDA’s drug center, which evaluates the drug to determine whether it
may be approved.” Using the Genentech drug MPDL3280A, an engineered, anti-programmed
death ligand 1 (anti PD-L1) antibody as a case study, I will seek to show that not only does this
standard put unnecessary weight on solely the drug development party, but that there is currently
no way around the standard for companies.
To further understand efficiencies in the field of drug development, as well as its
financial and regulatory future in healthcare around the world, I will also seek to reflect upon the
types of models used by payers in various countries. One factor that dramatically differentiates
the US from other countries is the amount of money that can be injected into healthcare at any
one time. The United States has by far the highest per capita healthcare spending at $8362
5. current international dollars, as adjusted using the purchasing power parity. For this reason, there
has been a desire, but no real need, to change the underlying healthcare system to accommodate
for clinical or cost effectiveness. Using the UK and France as examples of different models that
could be used by payers as a clear standard from which reimbursement decisions can be better
made in the future, I will also illustrate that a more efficient regulatory system is not the reality
of the distant future, but rather that of a more proximal one.
6. MATERIAL AND METHODS
The project had two objectives. The first was to consolidate the regulatory environment
surrounding Laboratory Developed Tests (LDT) and the normal FDA 510(k) or PMN process by
which drug developers must obtain approval for the use of their diagnostic tests. This
information was for the most part completed using of the ASU library database from which
much of the information and articles of necessary information were excavated for use.
Furthermore, the case study of the Genentech and PD-L1 drug was conducted through interview
of Roche Tissue’s Market Access Leader Jim Armstrong, as well as Genentech publications. The
secondary objective was to review the requirements and considerations of the United Kingdom
and France’s healthcare oversight committees in order to identify key requirements. This was
done via ASU’s library database as well as the website for the French Health Assessment Board,
Haute Autorité de Santé (HAS).

Technology Assessment Process in the United States
In the United States, private payers and Medicaid payers are the primary decision makers
regarding coverage for diagnostic tests. The decision is reached through an analysis of the
“expected volume of use, cost-impact to the organization, and concerns over data and/or clinical
utility of products.” Payers produce individual HTA reports to provide information regarding the
costs, effectiveness, and current/expected impacts of various healthcare tests and treatments.

organizations, e.g., Hayes, ECRI, and BCBSTEC.

Technology Assessment Process in the United Kingdom
In the United Kingdom, the National Coordinating Centre for Health Technology
Assessment (NCCHTA) is in charge of producing HTA reports to provide information to those
whom provide, receive, and plan care through the Nationalized Healthcare System (NHS). The
HTA report provides details regarding the costs, effectiveness, and current/expected impacts of
various healthcare tests and treatments [9].
The National Institute for Health and Care Excellence (NICE) is in charge of selecting
interventions for review based on a set of published guidelines:
1. “Is the technology likely to result in a significant health benefit, taken across the NHS as
a whole, if given to all patients for whom it is indicated?” [9]
2. “Is the technology likely to result in a significant impact on other health related
government policies (e.g. reduction in health inequalities)?” [9]
3. “Is the technology likely to have a significant impact on NHS resources (financial or
other) if given to all patients for whom it is indicated?” [9]
9. 4. “Is the Institute likely to be able to add value by issuing national guidance? For instance,
in the absence of such guidance is there likely to be significant controversy over the
interpretation or significance of the available evidence on clinical and cost
effectiveness?” [9]
Technology Assessment Process in France
In France, a product’s medical benefit is determined by the use of five criteria: “efficacy
and safety; position of the medicine in the therapeutic strategy and the existence or absence or
therapeutic alternatives; severity of the disease; type of treatment: preventative, curative, or
symptomatic; and public health impact.” Based on these five criteria, one of five medical benefit
levels is assigned to the product by the Commission d’Evaluation des Médicaments (CEM):
insufficient to justify a reimbursement, weak, moderate, important, or major, in increasing
degrees of perceived benefit.
There are several different governmental bodies that oversee the technological
assessment process in France, each with a different responsibility in the overall process. The
Agence Française de Securité Sanitaire des Produits de Santé (AFSSAPS) oversees inspection of
industrial sites, controls laboratories and scientific evaluation, and controls advertising. The
Haute Autorité de Santé (HAS) oversees assessment of medical procedures, medications, and
medical devices, publishes guidelines, certifies doctors, and determines accreditation of
healthcare organizations. The Commission Nationale d’Evaluation des Dispositifs Médicaux et
des Technologies de Santé (CNEDiMTS) further assesses medical procedures that were
previously assessed by HAS [10].
10. DISCUSSION
The FDA has released guidelines on the regulation of the Biomedical Diagnostics test
that are made independently by LDTs [11][12][13]. However, the current regulatory system has
caused many to scratch their heads; the regulatory environment for companion diagnostics is
quite clear: in order for a targeted therapy drug to be approved, it must have an effective
diagnostic tool with which you can determine if a patient falls within certain, genetic or
otherwise, specifications for the use of the drug [12][14]. That concept is not hard to grasp and it is
quite logical to enforce the need to provide a companion diagnostic with the drug. This same
stringent scrutiny is not, however, afforded to LDTs. The current problem with LDTs is that
there is never any direct link to them and any kind of regulatory agencies. Laboratories that are
overseen by CLIA either are or are not allowed to perform certain tests, based on the complexity
of the test and the CLIA requirements the lab meets to prove their capability of doing high
complexity testing. If the laboratory passes the requirements laid out by CLIA, they can produce
any LDT with no oversight as to the efficacy of the test.
Jim Armstrong, the Market Access Leader at Ventana, first voiced these concerns
relaying that “there is no way to incentivize labs contracting to hospitals to use one assay over
another” (personal communication, June 26, 2015). For companies to even be able to market
their diagnostics, then, they need to make the antigen available to laboratories to train technicians
on the use of the assay and how to read it. Due to the fact that the product is held in the trials
phase, all diagnostics manufacturers have resorted to giving the raw components of the
11. diagnostic to labs for them to make their own tests. These raw materials, called Analyte Specific
Reagent (ASRs) are purchased by the lab and can be used for in-house LDTs. Any laboratory
that is capable of high complexity testing is then capable of running ASR based tests, and thus
can work around any restriction as to the regulation of LDTs. This is, in most cases,
economically prudent because it allowed labs to be ready to run a particular diagnostic for the
targeted therapeutic upon release of the drug thus eliminating the post release training period.
There is an increased prevalence of personalized medicine products available in the
market. In the case of oncology, this has many a time lead to not only competing drugs but
competing diagnostic assays that often use the same biomarker. Effectively, this means that
multiple diagnostic assays can, with different degrees of efficacy that will not be tested and
which are not necessarily developed hand-in-hand with the drug they are to be used with, can be
administered interchangeably and used to diagnose a non-small cell cancer variant that the
Genentech drug is effective in treating in lung and bladder instances of this cancer variant.
In the case of the Genentech drug MPDL3280A for example, the companion anti-
programmed death ligand 1 (anti PD-L1) diagnostic being co-developed and tested is going to be
competing with anti-PDL1 assays of two other companion diagnostic producers; Dako is making
the test for Merck and Bristol Myers Squibb. Whilst the Genentech drug and diagnostic is being
held for approval as both Roche products go through phase three trials, there is already no
guarantee that companies will go through the approval process the FDA requires and come out of
it being able to profit from their diagnostic products, each of which were a cost incurred in
research and development. This means that when MPDL3280A is approved for use, laboratories
will have three routes by which they can test for patients being positive for the PD-L1 antigen:
12. The Ventana assay, the Dako assays, and the LDTs that have been in the works since Ventana
Medical Systems released ASRs to labs that will be running the assay in the future.
Essentially, FDA oversight is thorough and ensures the production of a high quality
product. However, contrastingly, oversight of LDTs by CMS’ CLIA program at no point
addresses the clinical validity of any test. Testing for the analytical validity and putting it under
the trials, inspection, and scrutiny of the FDA whilst not ensuring that only the tests that have
been shown to have analytical validity be used to test for efficacy in the hospital is like asking
Pfizer to put in the research and development costs involved with Lipitor and then allowing
independent third parties to produce the same product with no proof of efficacy at a price
undercutting the pricing strategy that would be necessary to earn back the R&D dollars. The first
step to fixing the inefficiency of the current system, then, is to either have the FDA extend its
regulatory authority to include LDTs or expand the activities of CMS’ CLIA to include clinical
validity of individual test produced by laboratories in cases where the diagnostic is considered
high complexity. By including LDT review in a premarket capacity, the validity of these tests
can span beyond the doors of the laboratory in which they were developed.
Furthermore, it is important to consider that the US healthcare system is very much
decentralized and serves its citizens via three primary payor bodies. The first is private coverage,
which is by far the largest percentage of privately insured citizens among all three comparable
health care systems. As Table 1 shows, only about 1% of the UK population is privately covered
with 99% having nationalized healthcare. In France, the mandatory health insurance system
ensures that every member of the country of 63.9 million is covered by the government. The
other two insurers in the US are Public Coverage and Medicare with about 14.11 million
13. uninsured as of 2009, a number that has shrunk to 12.9% since the passing of the Affordable
Care Act.
The National Institute for Health and Care Excellence (NICE) and the National
Coordinating Centre for Health Technology Assessment (NCCHTA) in Britain and Comité des
Médicaments et des Dispositifs Médicaux Stériles (COMEDIMS), a subcommittee of the
Hospital Medical committee in France are the main technology assessment bodies that are the
decision makers. This presents us yet again with a rather large leap when it comes to the reality
of the gap in the assessment bodies. The whole of the decision making process is centralized to
these national bodies and some regional assessment boards while in the US, private payers,
whose actions are far more reliant on stakeholders in the long run make technology assessments.
Our assessment process is different than that of the UK and France because whereas
central bodies, often bound by EU regulations that allow for citizens of one country to get
benefits in another work in assessment committees with clear cut requirements from all
pharmaceutical producers, US payers can choose to outsource even their assessments to third
parties that will do all of their analysis for them. This process stems from the fact that unlike the
UK and France, any drug that has proven valid in the eyes of the FDA can and will be
reimbursed, even if begrudgingly. Here we can take a lesson from France, a country in which
drug approval is completely separate from reimbursement, which is done one a gradient
according to the medical benefit level. In this way, a company cannot simply rebrand a product
at the end of a patent (i.e. Lipitor) and sell what is essentially generic atorvastatin as an
expensive branded product because the new drug would not demonstrate a significant advantage.
The trend toward the idea of significant benefit exists even in the UK’s NICE model for
assessment and reimbursement. Drugs are given value if they are the yes tick mark to questions
14. regarding bridging the gap in inequality. The final change we can make in our assessment system
move away from risk-benefit analysis towards cost-effectiveness metrics as these will better
allow payers to assess what drug is the best value for the expenditure [13][15][16]. This doesn’t
mean that just because a drug is expensive, it shouldn’t be reimbursed. However, it does help
bridge the gap between cost and end of life procedures by bringing into questions of the
opportunity cost of treating an older individual already living beyond their life expectancy with
drugs that are more expensive and could reduce their quality of life in their last months; it will
also allow for many other qualitative measures like the drug’s anticipated effect [16]. That is you
would expect to pay more for a curative product than a pill you have to take for the rest of your
life with regard to monthly payments [13].
Ideally, the FDA has done a respectable job of being strict with its conditions. It is now
time to be fair with those conditions such that dramatic medical advances are no stunted by lack
of proper reimbursement and assurances that biologics developed alongside new drug receive a
fair chance to prove their value. By changing our approach to how we reimburse promising
technology and promoting a health assessment environment that allows for stand out drugs and
diagnostics to do just that, we will, if nothing else, make the medical environment simpler and
more efficient for all its stakeholders.
