Transcript of "Should I Participate in a Clinical Trial?"

  1. 1. SHOULD I PARTICIPATE IN A CLINICAL TRIAL? GARY C. PIEN, MD/PhD Allergist/Immunologist SMG Research Director June 5, 2013
  2. 2. OBJECTIVES • Understand what is a clinical trial • Examine the role of medical research and clinical trials in developing new therapies • Review the drug development process • Discuss ethical and scientific safeguards to protect research participants • Highlight ways to participate in medical research
  3. 3. WHAT IS A CLINICAL TRIAL? • medical research • novel methods to diagnose, prevent, or treat diseases  new drugs  new combinations of drugs  new indications of an existing drug  new surgical techniques or medical devices  new test for diagnosing disease or risk of disease  establishing new guidelines or recommendations • goal is to determine if new intervention is safe and effective http://www.nih.gov/health/clinicaltrials/basics.htm
  4. 4. TYPES OF CLINICAL TRIALS NATURAL HISTORY • how does a disease change, progress, or develop over time? PREVENTION • how to prevent a disease from developing or recurring? SCREENING OR DIAGNOSTIC • how to detect a medical condition or diagnose a particular disease QUALITY OF LIFE • measure ways to improve comfort and quality of life with a chronic illness TREATMENT • testing a new medication, procedure, or device http://www.nih.gov/health/clinicaltrials/basics.htm
  5. 5. CLINICAL TRIAL “PHASES” PHASE I • healthy human volunteers (20-80) • establish safety and side effects • evaluate drug absorption, metabolism, clearance PHASE II • first use in patients with disease/medical condition (100-300) • limited duration, narrow patient criteria • establish efficacy, short-term safety http://www.nih.gov/health/clinicaltrials/basics.htm
  6. 6. CLINICAL TRIAL “PHASES” PHASE III • confirmation of therapeutic benefit under “real-life” conditions • 1000-3000 patients • wider patient criteria • often multi-center, multi-national, comparative • longer-term safety, drug interactions, contraindications PHASE IV • after-market trials • long-term safety data • identify rare side effects http://www.nih.gov/health/clinicaltrials/basics.htm
  7. 7. HOW A DRUG COMES TO BE DiMasi et al, 2003, Journal of Health Economics 22: 151–185. Preclinical 1 - 6 yrs 1 in 8 move on Drug discovery and development
  8. 8. HOW A DRUG COMES TO BE DiMasi et al, 2003, Journal of Health Economics 22: 151–185. Preclinical 1 - 6 yrs 1 in 8 move on Drug discovery and development http://sydney.edu.au/bmri/research/brain-drug-discovery/index.php
  9. 9. HOW A DRUG COMES TO BE DiMasi et al, 2003, Journal of Health Economics 22: 151–185. Clinical Phase I • safety • $15 million • 22 months Phase II • safety, dosing, efficacy • $23 million • 26 months Phase III • safety, efficacy, side effects • $87 million • 31 months Investigational new drug application 6 - 11 yrs 30% 14% 9%40% Preclinical 1 - 6 yrs 1 in 8 move on Drug discovery and development
  10. 10. HOW A DRUG COMES TO BE DiMasi et al, 2003, Journal of Health Economics 22: 151–185. Clinical Phase I • safety • $15 million • 22 months Phase II • safety, dosing, efficacy • $23 million • 26 months Phase III • safety, efficacy, side effects • $87 million • 31 months Investigational new drug application 6 - 11 yrs 30% 14% 9%40% Approval 1-2 yrs 8% New drug application Market 11-14 yrs Phase IV also post- market surveillance Preclinical 1 - 6 yrs 1 in 8 move on Drug discovery and development
  11. 11. PROTECTION OF RESEARCH PATIENTS http://www.mastercontrol.com/newsletter/good-clinical-practices-review-application.html
  12. 12. PROTECTION OF RESEARCH PATIENTS DECLARATION OF HELSINKI - 1975 • protect health, dignity, integrity, privacy of volunteers • study must conform to accepted scientific principles • research protocol must be established and followed • protocol must be approved by independent ethics committee • benefits must outweigh risks • participation must be voluntary, without duress • informed consent must be obtained • privacy and confidentiality must be protected http://www.wma.net/en/30publications/10policies/b3/
  13. 13. PROTECTION OF RESEARCH PATIENTS BELMONT REPORT - 1979 • Smithsonian Institute • respect for persons – autonomy of patients • beneficence – protection from harm, ensure well-being of patients • justice – results should benefit all (not just those who can afford it, etc) COMMON RULE - 1981 • US federal policy derived from Declaration of Helsinki • enforces compliance by research bodies • safeguards informed consent • provides for IRB regulations • establishes protections for vulnerable populations (prisoners, children, pregnant women) http://www.mastercontrol.com/newsletter/good-clinical-practices-review-application.html
  14. 14. PROTECTION OF RESEARCH PATIENTS ICH • International Conference on Harmonisation • brings together regulatory bodies of Japan, Europe and US • develop standards for ethical and scientific research • quality, safety, efficacy, regulatory issues • reduce duplicate testing GCP • Good Clinical Practices • human subject protection – patient rights, integrity, confidentiality • standards for design, conduct, performing, monitoring, recording data http://ichgcp.net/2-the-principles-of-ich-gcp-2 http://www.wma.net/en/30publications/10policies/b3/
  15. 15. PROTECTION OF RESEARCH PATIENTS IRB • institutional review board • doctors, scientists, lay people • scientific, ethical, and regulatory oversight • ensure that rights and welfare of participants are protected • appropriate recruitment population? • how are patients recruited? • adequate disclosure and informed consent? • are risks too great? http://www.fda.gov/forconsumers/consumerupdates/ucm134723.htm
  16. 16. PROTECTION OF RESEARCH PATIENTS FDA • Food and Drug Administration • has authority over clinical trials • inspects and audit research sites • ensures rights and welfare of participants • reviews data quality and integrity http://www.fda.gov/forconsumers/consumerupdates/ucm134723.htm
  17. 17. PROTECTION OF RESEARCH PATIENTS INFORMED CONSENT • disclose purpose and protocol for study • adequate information for potential volunteers to decide whether to enroll • Q&A opportunity for investigator and patient • no obligation to join a study • consent must be written • consent may be withdrawn at any time http://www.fda.gov/forconsumers/consumerupdates/ucm134723.htm http://ori.dhhs.gov/education/products/RCRintro/c03/0%20c3.html

  19. 19. CONSIDERATIONS BEFORE ENROLLING RISKS • potential side effects from treatment (may be minor to life-threatening) • may be assigned to a placebo control group • impact on daily activities (time commitment, etc) BENEFITS • access to new treatments before they are widely available • regular and careful medical follow-up with research team during trial • help contribute to medical science • play more active role in one’s medical care • results of the study may benefit other people and future generations http://www.nih.gov/health/clinicaltrials/basics.htm
  20. 20. QUESTIONS TO ASK THE STUDY • what is the purpose of the trial? • why do we think this new treatment will work or help? PARTICIPATION • what tests or procedures are required during the study? • how do these tests/procedures differ from standard treatment? • who will be in charge of my care? RISKS AND BENEFITS • benefits to me? • what are the chances of side effects? • how serious are those potential side effects? • are there other options to treat my condition? http://www.nih.gov/health/clinicaltrials/basics.htm
  21. 21. QUESTIONS TO ASK QUALITY OF LIFE • how will this trial impact my daily living? • how long will the study last? • what are my responsibilities? • can I take other medications during the trial? COST • will I have to pay for any part of the trial? • will my health insurance cover any part of the costs? • are there any travel expenses? • is there compensation for my participation? http://www.nih.gov/health/clinicaltrials/basics.htm
  22. 22. REASONS FOR ENROLLING (OR NOT) ENROLL • a trusted physician recommended study • additional attention and care through trial participation • encouraged by friends/family • altruism • (desire to live) DECLINE • anxiety about randomization • worry not best treatment • logistical difficulties • concerned about side effects • friends/family against study Albrecht et al, 2003, Journal of Cancer Educ 18: 210–214.
