Research Update 2012

  1. 1. RESEARCH UPDATE2012 JUVENILE ARTHRITIS CONFERENCE, ST LOUIS, MO Mara L Becker, MD MSCE Associate Professor of Pediatrics, UMKC Children’s Mercy Hospitals and Clinics, Kansas City, MO
  2. 2. Disclosures
  3. 3. Break Down Why do we need to be even talking about research in children?  What makes kids different?  How can research benefit my child? Research Basics  Research vs. clinical care, risks vs. benefits, safety  Types of research  Examples of new clinical trials currently or soon to be enrolling Other ways of contributing/getting involved
  4. 4. Sir William Osler, 1903 ―the most influential physician in history‖ ―Who can tell of the uncertainties of medicine as an art? The science on which it is based is accurate and definite enough… but no two individuals react alike and behave alike under the abnormal conditions which we know as disease‖ ―The good physician treats the disease; the great physician treats the patient who has the disease‖ His description of the inadequacy of treatment methods for most disorders was a major factor leading to the creation of the Rockefeller Institute for Medical Research in New York
  5. 5. Startling facts… • By age 5 yrs, 95% of children have been prescribed a medication, with an average of 8.5 prescriptions and 5.5 different medications • Medicines, devices and treatments are often NOT tested in children – In fact, 70% of medicines prescribed to children have been tested ONLY IN ADULTS • ―Off-Label‖ use of drugs in children is commonplace – 79% of hospitalized children received at least 1 off label drug – Utilize a weight based dose adjustment for children – Necessary… but NOT ENOUGH!!Loebstein R et al, Pediatr Rev, 1998 (19)12:423-428, Shah S et al, Arch Pediatr Adolesc Med, 2007 (3) 161: 282-90
  6. 6. Children are not little adults! Lucas at The Magic House– St Louis, MO
  7. 7. Stages of growth: Makes pediatric patients unique at every stage • Differences in digestion and enzyme function • Differences in muscle mass and organ size • Differences in the effect of therapies upon a growing body – Are there long term consequences? • Differences in how the disease acts in kids compared to adultshttp://www.nhlbi.nih.gov/childrenandclinicalstudies/whyclinical.php

  9. 9. Why should children be included inresearch? If we don’t include children in research, we leave them vulnerable to:  Incorrect drug dosing  Sideeffects  Doesn’t work  Not being prioritized for:  research targeted at disease CURE  genetic risk studies and counseling for future risk  Understanding the role of disease prevention  Understanding how complementary approaches may affect disease  Identification of biomarkers to guide disease activity or inactivity
  10. 10. Examples of HOW research can help my child?• Find the best doses of medicines to prevent harmful effects or under treatment• Making safe and easily administered medicines for kids (chewables, liquids, yummy tasting!)• Finding treatments to conditions that are expressed differently in kids compared to adults (Juvenile arthritis)• Finding treatments for new or existing diseases to improve health in the future (vaccines)• Understand how medicines affect growing children and their development
  11. 11. Research vs. Clinical Care• Research is done to help find out if a treatment or procedure is good for a large group of people with a certain disease or condition. Research helps to answer questions for the future health of those populations. Standard medical care, however, focuses on individual needs in the present• Similarities: – Researcher and your healthcare provider can be the SAME person – Setting may be in your regular clinic – The treatments may seem the same
  12. 12. Research vs. Clinical Care: questions to ask• How is this different from standard care? – Will I see different doctors and nurses for the study? – Will I go to a different hospital or clinic for the study? – Will the doctors and nurses ask me a lot more questions about my childs condition? – Will there be more paperwork or additional tests when we are in the study? – Will there be more rules and deadlines in the study?
  13. 13. Will my child benefit? Research is done to gain information about a disease, condition, drug or treatment that will benefit children in the future– different than regular medical treatment that is given to help a specific child However- there are potential benefits:  Helping future generations  Having access to new drugs or treatments, doctors or other families with same condition  Getting closer monitoring or additional testing
  14. 14. How will my child be protected? http://www.nhlbi.nih.gov/childrenandclinicalstudies /safety.php
  15. 15. How will my child be protected? Research team  Investigator, doctors, nurses, statistical experts, pharmacists  Determine the right study, performed in the right number of patients, done in the right way, with the right participants Institutional Review Board  an independent committee that reviews research plans and consent forms to make sure that people in a study are informed and protected. They review studies both before they start and throughout the study.
  16. 16. Protection of study participants, cont. Informed consent/Patient assent  Parent is given details about a study so that you can decide if your child should join a study. You are "informed" so that you can give your "consent" or okay. Nothing can happen until you consent to it.  Most children from age 7 can understand basic information if it is given at their level. So, in most studies, children are now asked if they agree (assent) to be in a study and are asked to sign an assent form. Data and safety monitoring board/medical monitor  impartial Board/person that oversees studies and says if a study should be changed or closed at any time for safety issues.
  17. 17. And remember your rights…  Ask as many questions as you’d like  You can say NO at any time, for any reasonwww.rfried.info
  18. 18. Research Organizations Specific toPediatric Rheumatology CARRA: Childhood Arthritis and Rheumatology Research Alliance  Typically manages investigator-initiated studies PRCSG: The Pediatric Rheumatology Collaborative Study Group  Handles drug industry-initiated research
  19. 19. Types of Research Observational Studies Translational Studies Clinical Trials Comparative Effectiveness Research (CER)
  20. 20. Observational studies Retrospective  In the past  Likely no consent will be obtained  Combine clinical data (without identifiers) to look for associations  This is a big part of the research we have to go on from the past  Ex:  Arthritis Rheum. 1977 Mar;20(2 Suppl):327-31.  Drs. Sullivan, Cassidy and Petty evaluated the charts of 33 patients with JDM treated with steroids, and found that the outcomes of these children were infinitely better than children NOT treated with steroids
  21. 21. Observational Studies Prospective:  Current/future  Collect specific information on patients, often over time  Registry  Ex.  CARRAnet registry (CARRA= Childhood Arthritis & Rheumatology Research Alliance)  observational retrospective and prospective study that enrolls children and adolescents with major rheumatic diseases followed at participating study sites. All patients with defined rheumatic diseases who are 21 years of age or younger and who are seen/followed at a CARRA site for medical care will be approached for participation in the registry.
  22. 22. Translational Studies Used as a bridge linking bench/basic scientific research with the patient  Multiple disciplines often involved  Goal for faster application of knowledge to patient Usually a combined collection of clinical information and biologic sample(s) (blood, urine, tissue, hair, etc) Ex.  Arthritis Rheum.2010 Jun;62(6):1803-12.  My work is in measuring methotrexate metabolites in cells to determine if different patterns or genetic associations are predictive of better or worse response to the medicine
  23. 23. Clinical Trials Compares 1 or more treatments Often randomized  Means your child may NOT get active drug/therapy Treatment follows very exact guidelines  protocol Not all patients will qualify  Inclusion and exclusion criteria Most scientifically rigorous and most expensive
  24. 24. Clinical Trials Phase 1  Safety doses Phase 2  Efficacy doses Phase 3  Compare drug to placebo, or current treatment- does it work? Is it safe? Phase 3 OLE  Open label extension gathers additional safety data and longer term info about treatment effects Phase 4  Large observational registries to Basic Science/bench experiments explore medication safety once drug approved by FDA
  25. 25. What do we have going on in clinicaltrials in the US?

  40. 40. Comparative Effectiveness ResearchAgency for Healthcare Research and Quality definition “A type of health care research that compares the results of one approach for managing a disease to the results of other approaches. Comparative effectiveness usually compares two or more types of treatment, such as different drugs, for the same disease. Comparative effectiveness also can compare types of surgery or other kinds of medical procedures and tests. The results often are summarized in a systematic review.” What does this actually mean??
  41. 41. Comparative Effectiveness ResearchWikipedia Comparative effectiveness research (CER) is the direct comparison of existing health care interventions to determine which work best for which patients and which pose the greatest benefits and harms. The core question of comparative effectiveness research is which treatment works best, for whom, and under what circumstances These clinical research trials measure effectiveness—the benefit the treatment produces in routine clinical practice.  This is different than many regular clinical trials, which measure efficacy--whether the treatment works or not in a controlled environment such as a clinical trial
  42. 42. Comparative Effectiveness Researchwhy useful for JA? Randomized Clinical Trials:  CER:  Expensive and time  More generalizable: ―real consuming world‖  YEARS to complete and  Easier recruitment (less millions of dollars inclusion/exclusion  Complex (inclusion/exclusion restrictions) criteria)  ―head to head‖ comparisons  Hard to recruit, especially in  Can assess patient-relevant rare conditions outcomes, and clinically meaningful outcomes  Can be less expensive  Potential to compare treatments at an individual and population level
  43. 43. CER in Juvenile Arthritis: the time isNOW… or soon! CARRA Consensus Treatment Plans (CTPs)  Observational CER within the CARRA registry  Formulated for several pediatric rheumatic diseases  CTPs developed over the past 1-2 years by polling the CARRA community of pediatric rheumatologists and reaching consensus about the most prevalent/agreed upon treatment plans for specific diseases  Now, ready to implement and study what plans are best!  Using the CARRAnet registry as the vehicle to collect clinical information on response/improvement, safety, patient quality of life, etc.
  44. 44. Role of the Arthritis Foundation Direct research grants  AF support for CARRA through the foundation to and CARRA sponsored support research that: research  biomarkers that predict  http://www.arthritis.org/ disease outcome, measure carra.php response to treatment in  http://www.arthritis.org/ JA. ja-research.php  Develops and/or assesses new drugs and non- pharmacologic methods to improve JA.  Assesses comparative effectiveness of different interventions for JA using the CARRA network.
  45. 45. Fundraising AF- sponsored events  Friends of CARRA  Jingle bell run/walk  raises money through  Arthritis walk private donations, grants and various fundraisers put on by parents and Locally sponsored friends across the country fundraisers  All of money raised goes  Can be designated to be directly to CARRA to used in childhood fund research to find the arthritis research only cause and cure for rheumatic diseases in children.
