The cost of DNA sequencing is dropping continuously. In very future, majority of the population will have access to their genetic background and they will be able to take it their doctor and will expect to receive personalized treatment rather than a drug that has worked for millions of people but not guaranteed to work for them. Pharmaceutical industry will eventually have to change their business model and transition to personalized medicine. I am wondering how this impacts the regulatory affairs in pharmaceutical industry. How the FDA is preparing itself and evolving to address this trend of change to personalized medicine?

Some one from the FDA can no doubt answer this question.

Let's step back and verbalize what we anticipate the "personslized" medicine will actually look like in practice. I anticipate that the main change will be in terms of disease diagnosis, for example based on gene analysis determining what drug would be most effective for an individual patient. No drugs will specifically be made for individual patients. The current Precision Medicine Initiative does not include developing personalized precision drugs, hence the treatment will still use the existing therapies.

First of all we have to define the needs of personalized medicine in specific and only then it can be applied efficiantly.second, it should include building a personal profile of ones needs as for the all taken drugs inpot and address also the interaction infuance between all the drugs input because now it is very much can cause more harm then help if not taking this issue into consideration . - ORIT more than 1 month ago

A wave of change? Not really. Just a normal progression...

Dear Vijay,
I think that FDA will have time to decide in early stages of personalizing medicine, because the main thing that needs adjustment is the quantity of drug a person should take to be effective.
If some existing drug is not effective, the second approach should be changing the drug, combining two drugs or using enhancers.
In the future, and taking on account the evolution of CRISP-like methods and gene therapies, the framework should change to include this as a new genome driven medicine.

The "one-size-fits-all medicines" description has been used by Mr. Carotenuto as a criticism. There is no need to be so negative; in fact, one-fits-all is perfectly fine for example for antibiotics, as long as physicians are willing to determine what particular organism / bacteria has infected the particular patient.
Somewhat incorrectly termed "personalized medicine" - a better term is "precision medicine" approach does something similar, by first determining the actual cause of disease and then applying appropriate therapy. It is not intended to be tailored to individual patients but simply to a subset of patients that possess the appropriate genetic / other relevant biological background.

Dear Kerel, I perfectly agree with your statement. I didn't want to be critic, I was arguing about that the new era of personalized medicine is just started. My previuos inputs showed which is the state of the art. I am far from critical, I am working in this field and I believe that the results of these approaches for both personalized medicine and precision medicine will soon be quite practical. - Pietro 1 month ago

The biggest cost of drug development is not in drug discovery and development (this cost being under the control of pharmaceutical companies), but in the clinical-trial phase (the cost of this is driven by clinical investigators and their institutions). Further, an average cost of drug development is high because only few percent of drugs entering development reach the market (due to failure of clinical studies to reach the desired outcomes).
It would be very useful to come up with ideas as to how to implement the "One by one, painfully, there can be quality driven improvements along with efficiencies that ultimately will trim down costs of care" approach could be applied to clinical studies...

The Personalized Medicine is just an ongoing practice fro FDA. I'm describing a briefly report to reply to the main question.
In 2016, for the third year in a row, personalized medicines accounted for more than 20 percent of all new
molecular entities (NMEs) approved by the U.S. Food and Drug Administration (FDA). FDA’s Center for Drug
Evaluation and Research (CDER) approved 22 NMEs, new drugs, agents or
therapeutic biologics, in 2016. Of the 22, the Personalized Medicine Coalition (PMC) classified six of them — more
than 25 percent — as personalized medicines, continuing a trend that PMC first documented in 2014 when it pointed out that nine of 41 NMEs approved that year are personalized medicines. The analysis underlines that nearly one of every four drugs the agency approved from 2014 to 2016 is a personalized medicine. That ratio is a sharp increase from 2005, when personalized medicines accounted for just 5 percent of NME approvals. When evaluating NMEs, PMC categorizes personalized medicines as those therapeutic products for which the label includes reference to specific biological markers, identified by diagnostic tools, that help guide decisions and/or procedures for their use in individual patients.
Newly Approved Medicines
The six personalized medicines approved in 2016 include:

  1. Rubraca (rucaparib) for the treatment of advanced ovarian cancer. The decision to use this product
    is informed by the BRCA1/2 biomarker status in patients.
  2. Exondys 51 (eteplirsen) for the treatment of Duchenne muscular dystrophy. The decision to use
    this product is informed by the DMD mutation biomarker status in patients.
  3. Epclusa (sofosbuvir and velpatasvir) for the treatment of chronic hepatitis C infection. The decision
    to use this product is informed by the HCV genotype status of the viral infection in patients.
  4. Tecentriq (atezolizumab) for the treatment of advanced or metastatic urothelial cancer and
    metastatic non-small cell lung cancer. The decision to use this product is informed by PD-L1
    expression levels in the tumors of patients.
  5. Venclexta (venetoclax) for the treatment of chronic lymphocytic leukemia. The decision to use this
    product is informed by the chromosome 17p deletion biomarker status in patients.
  6. Zepatier (elbasvir and grazoprevir) for the treatment of chronic hepatitis C infection. The decision
    to use this product is informed by the HCV genotype 1 and 4 biomarker status of the viral infection
    in patients.

Reading this informative comment it occurred to me that the term "personalized medicine" is somewhat of an exageration. To some extent it matches the definition that designation as "personalized" "meets someone's individual requirements".

However, to be more exact, the "personalized" medicines in the current context simply add more definition, specification about what group of patients the drug should be used.
Every FDA-approved drug comes with a package insert that clearly describes its INDICATIONS AND USAGE. Adding to this information more specific description relating to the mode of drug action does not make it "personalized". It simply narrows the size of the population for which the drug may be effective...

Yes, the new era is just started:
THE PHARMACEUTICAL industry makes billions of dollars a year selling one-size-fits-all medicines. But now the race is on to come up with tailor-made drugs that will treat people based on their individual genetic makeup.
Drug companies hope to create a map of genetic landmarks that will become a potent new tool for uncovering the minute inborn differences that make some individuals particularly susceptible to certain diseases. With that knowledge, the drug makers hope to develop safer, more potent drugs that can more precisely target the variety of biological quirks that underlie each major disease. Their goal: a cornucopia of personalized medicines that will produce huge profits into the next century.

Given the politics in Wash DC these days, its confusing with mixed signals as to trend or speed of change. However, the direction for change and easing regulatory burdens is now becoming much clearer. FDA speeding up drug approvals, CMS reducing administrative burdens, and some Executive Orders to-date by Trump clearly support allowing progress to be made while embracing new technologies in a safe manner.

Let me make few points.
Cost of DNA analysis is of little significance in the current care for patients. 1. physician is unlikely to know what the heck the analysis means in relation to the patients condition, and 2. if he does, appropriate specific, "precision" medicines are not yet available.
Further, personalized medicines are unlikely ever to be made to fit individual patients. As it is now, medicines are developed for groups of patients with the same disease and a similar biological / genetic / etc. background.
Two government programs are currently under way - Precision Medicine Initiative to generate new information about the nature / mechanisms / of diseases and life-style effects on disease, and Accelerating Medicines Partnership to generate knew knowledge so that clinical srudies could be designed to fail less often. Neither of these projects aims to develop new drugs; that task is being left to pharmaceutical industry.

Easing regulatory burden will not cut it. We first need more knowledge about diseases and consequently better drugs. Making regulations easier is likely to achieve only one thing - more bad drugs will be made faster!

Good point about continuing bad drugs, however, there are costs associated with everything that is done in research, development, production, marketing and sales. One by one, painfully, there can be quality driven improvements along with efficiencies that ultimately will trim down costs of care.

Perhaps the biggest savings actually comes in contracting with 3rd parties and middleman during marketing phase of the drug.
