Editor's Notes
- #3 - Her story brought up the awareness about the importance of disease risk assessment How genetics provides insight into your health and can be used as a preventative measure to manage your health and lifestyle Your diagnosis can prevent catastrophic outcomes
- #4 The purpose of Disease risk: to identify what is the likelihood of developing a certain inherited disease This is expensive testing – few thousands dollars, more complex analysis of your family gene pool Insurability concerns Drug Response Test: what we will focus on today Very different type of genetic testing called Pharmacogenetics It’s based on how
- #5 Raise your hand How many of you had unwanted side effects to a medication you’ve taken? I guess you guys are still very young We as humans share 99% of our DNA, it’s only that 1% that makes each of us unique
- #6 There are many factors that impact how we respond to the medication and whether it’s working for us. Environmental (diet/tobacco use), physiological (age, sex, weight, disease status). Genetic factors play a big role as the scientific literature points out that 95% of a……… CYP are the main family of genes responsible for drug metabolism There is a lot of variability in drug efficacy rates and that has a big impact It has been documented that genetic factors are responsible of up to 95% of drug response. Drug efficacy rates for most major drugs range from 25% to 60% Mariya: Get reference for this slide
- #7 For slow metabolizers, don’t get any improvement. May need to take an alternative medication that your body can metabolize. Morphine on its own If you ultra-fast metabolize of codeine: short-term pain relief, increase in developing addiction you will get Up to 50% are not getting a full impact from Codeine as they cannot metabolize it into Morphine, not getting therapeutic effect, potentially side effects by continuing to take the wrong dose. Toxicated…. Only 48% can metabolize it normally 2% ultra-fast metabolizers, get only temporary relief for a couple of hours
- #8 Using a standard dose for all patients: A lot of times they see one size does not fit all
- #9 FDA has started updating drug labels to include pharmacogenetic recommendation where there is clinical evidence that drug dosage should be optimized with genetic test. It’s not enforceable but it’s recommended It’s an active role that FDA has taken to try and improve the health outcomes and patient safety. In the past year, FDA has increased drug labelling from 100 to 150.
- #10 CPIC follow FDA labels and follow clinical evidence to publish clinical dosing guidelines Purpose of CPIC: Make it easier for clinicians by providing clear guidelines on dosing optmiziation
- #11 Only 200K reported ADR’s causing 10K – 22K fatalities, costs the healthcare system $13.7-$17 Bil/yr The number #1 reason for discontinuation of medication: Adverse side effects One of our SEO analytics shows that GYI websites gets the most hits for Adverse side effects searches People are using Dr. Google to understand what side effects they may anticipate from taking medication 50% of prescriptions don’t get filled potentially due to the fear to side effects Medications are designed to treat specific symptoms, and they work most of the time. This is a pill for your cholesterol, This one is for your heart.. And this one is for your hypertension or diabetes... However frequently people do not experience expected clinical benefits or even worse suffer from adverse side effects. Why this happens?
- #12 Adherence requires patient to believe there is a benefit to the prescribing medicine and that they will not experience side effects
- #14 A lot of focus on managing Specialty drug spends. Most of drug spending is for chronic conditions With the aging population, the drug spend on chronic conditions will only going to get worse.
- #15 As a way to mitigate concerns around: Non-adherence and unwanted side effects Poor health outcomes Wasted drug spending PGx offers: In order to better manage patient health outcomes and reduce wasted healthcare spending, PGx offers
- #16 My aunt: Put on Brilinta – would’ve saved her insurance company and avoid poor health outcomes with a medication that just did not work for her Eliminate trial and error prescribing, would provided a physician with a guided tool to predict health outcome of my aunt on plavix
- #19 Where are the cost savings for employers? Better health outcomes More effective drug utilization Healthier, happier, more productive employees
- #20 Slide 53 the longer it takes for a person to find a correct medication, the more it costs the healthcare system, and employers, if you don’t identify the high risk people, it costs you!!
- #21 Wide adoption difficult without education of physicians and clarity in reimbursement structure
- #22 Simple message to reinforce benefits, at end “better health outcomes for people!”
- #23 Provide patients confidence in that their medication will work for them, they are more likely to take it This is what PGx is helping to do by predicting what medication would work best for the patient
- #26 This is a real example Ruslan consulted
- #27 Despite the known clinical benefits of PGx, physicians are not well informed or educated on the benefits of PGx. Many don’t even know that the companies exist that can provide this service. We have been going to see a number of Family health teams. Physicians seem to be fascinated and some are starting to order some tests. However, without clarity around reimbursement for patients And without making the ordering of the test integrated into physician clinical workflow, the adoption is slow.
