1 Safety Workshop: Part I Clinical Trial Safety and Safety Monitoring Ling Chin, MD, MPH NIAID/DAIDS/Office of Policy for Clinical Research Operations Durban, South Africa May 13, 2011 Ling Chin, MD, MPH NIAID/DAIDS/Office of Policy for Clinical Research Operations Durban, South Africa May 13, 2011

2 Objectives At the conclusion of this workshop, participants will be able to demonstrate an understanding of: Clinical research involving human subjects Current context regarding safety in clinical trials The concept of safety and safety monitoring and how it relates to clinical trials research Protocol requirements pertaining to areas relevant to safety Key roles and responsibilities related to safety Safety and adverse event terminology Expedited reporting of adverse events 2

3 Objectives - continued Assuring safety in clinical trials The adverse event life cycle What makes a well-documented adverse event, including a comprehensive narrative How to assess an adverse event case, including causality assessment 3

4 History of research involving humans 1747: Lind: first recorded clinical trial: British Navy surgeon, evaluated 6 different interventions on 12 sailors for the treatment of scurvy 1897: Sanarelli: discovered bacillus of yellow fever, produced yellow fever in 5 patients 1898: Osler: “To deliberately inject a poison of known high degree of virulency into a human being, unless you obtain that man’s sanction, is not ridiculous, it is criminal” 1901: Walter Reed: yellow fever research that included: Self- experimentation, Written agreements with other subjects, Payment in gold, Restriction to adult subjects, Using the phrase “with his full consent” : Nazi medical war experiments : Tuskegee Study of Untreated Syphilis in the Negro Male 4

5 5 History of research involving humans

6 Regulations: Federally Supported Research Involving Human Subjects 45 CFR 46: Protection of Human Research Subjects Applies to all research involving human subjects Institution must provide assurance of compliance, such as a Federal Wide Assurance (FWA) on file with the Office for Human Research Protection (OHRP) FWA provides assurance that research is conducted in accordance with the regulations Research reviewed and approved by IRB Subject to continuing review by IRB 6

7 Regulations: Non-Federally Supported Studies Involving Human Subjects 21 CFR 50: Protection of Human Subjects Clinical investigations regulated by FDA Requirements for informed consent Elements of informed consent Documentation of informed consent Form approved by IRB 21 CFR 56: Institutional Review Boards Clinical investigations regulated by FDA Requirements for IRB review Membership, functions, review procedures, etc Criteria for IRB approval 7

8 NIH Research Must comply with regulations pertaining to research involving human subjects, investigations of new drugs, biologics, or devices, or new indications, or use in new populations HHS, OHRP FDA Must adhere to NIH and Institute Policies for clinical research and conduct of clinical trials Additional monitoring bodies: Network-specific clinical safety monitors/groups, IRBs, DSMBs 8

9 IRB Review Initial and continuing review At convened meetings (at intervals appropriate to level of risk; not less than 1/year) Majority of members are present; Approval by majority Approval of Informed Consent Unanticipated problems involving risks to human subjects or others Any instance of serious or continuing non-compliance with regulations, requirements, or determinations of the IRB 9

10 IRB Review: Approval Criteria Risks to subjects are minimized: i.By using procedures consistent with sound research design which do not unnecessarily expose subjects to risk ii.Whenever appropriate, by using procedures already being performed for diagnostic or treatment purposes Risks to subjects are reasonable in relation to anticipated benefits, and the importance of the knowledge that may reasonably be expected to result Other criteria 45 CFR or 21 CFR

11 Safety Monitoring Committee  Internal process, NOT independent  Members include DAIDS MO, DMC clinical affairs safety associates, Protocol Co-chairs, Protocol Study Physician  Review safety events as study is ongoing Review of AEs at stated frequency e.g. monthly Assure reportable events are submitted to DAIDS Address safety concerns e.g. if safety rules are met (a-priori specification) 11

12 Data Safety and Monitoring Boards (DSMBs) / Data Monitoring Committees (DMCs) Government agencies e.g. NIH and the VA, have required the use of DSMBs in certain trials Current FDA regulations, impose no such requirements except under 21 CFR 50.24(a)(7)(iv) for research studies in emergency settings in which Informed Consent is excepted Independent group 12

13 Group of individuals with pertinent expertise; reviews accumulating data from one or more ongoing clinical trials: Clinicians with expertise in relevant clinical specialties At least one biostatistician knowledgeable about statistical methods for clinical trials and sequential analysis of trial data A medical ethicist, and/or patient advocate Other scientific areas: toxicologist, clinical pharmacologist, epidemiologist Advises the sponsor: Continuing safety of trial subjects and those to be recruited Continuing validity and scientific merit of the trial 2 important considerations: Confidentiality, COI. Knowledge of interim results could influence conduct of the trial 13 Data Safety and Monitoring Boards (DSMBs) / Data Monitoring Committees (DMCs)

14 Perspective Differing viewpoints on safety requirements:  Impose a burden on investigators Cumbersome bureaucratic hindrance Holds back pace of science Delays availability of new or much needed treatments  Represent only a minimal standard What is at least reasonable, practical Not what would be most ideal 14

15 Participants in research are voluntary Placed their faith in the investigators Participation is a gift in the service of the public interest Investigators must not betray the public trust Must conduct trials with ethical and scientific integrity Must implement high standards for human subject protections Must assure participant well-being and safety at all times 15 Perspective

16 Current Safety Environment 16 Increasing public demands for safety data Fast track approvals Post-market events leading to changes in labeling e.g. additonal precautions, black box warnings Food and Drug Administration Amendments Act of 2007 (FDAAA): Provides FDA with additional requirements, authorities, and resources with regard to both pre- and postmarket drug safety Global reporting to EMA and regulatory agencies of European Union (EU) member states, other countries throughout the world New Final Rule 21 CFR : focus on signal detection (only submit evidence-based Serious Unexpected Suspected Adverse Reactions), encourage noise reduction (less submission). Sponsor and investigator responsibilities to report.

18 Safety Monitoring

19 Roles and Responsibilities – Site Investigator

20 Roles and Responsibilities – Research Staff

21 Roles and Responsibilities – Study Clinician/Physician

22 Assurance of Safety and Well-Being: Research vs. Medical Roles 22  Emergency intervention vs. Non-emergency care Acute on-site management, as necessary, and per site SOP Referral to care when stable  Research provisions vs. Clinical care Provide interventions permitted by the protocol Follow protocol specifications for toxicity management Beyond protocol specifications, refer out for clinical care

23 Clinical Role vs. Research Role 23

24 Therapeutic Misconception 24 Subjects think they are receiving proven interventions, per their usual clinical care, despite participating in a research study Informed Consent Process must not be trivialized or relegated to administrative status Check for understanding Time for questions, making decision Physicians think they can provide interventions, per usual practice Strict adherence to protocol provisions for care, toxicity management Decide if subject can continue in study

25 Roles and Responsibilities – Study Clinician/Physician 25 Study product: Per site, per study? Study status: Safety pause, clinical hold, early termination? Study product: Per site, per study? Study status: Safety pause, clinical hold, early termination? Study product: Dose held, changed, or discontinued? Study participation: Continue, withdraw? Study product: Dose held, changed, or discontinued? Study participation: Continue, withdraw? Action taken with Study product after AE Action taken with Study product after AE Subject Study

26 Roles and Responsibilities – Study Team 26 Safety: Ensure safety and well being of subjects at all times Monitor safety across all study sites Review all safety data at specified intervals Discuss need for change(s) driven by safety Data: Ensure data integrity to assess the risks/safety profile of the study intervention Data capture; especially safety data Be cognizant of expedited reporting requirements for safety data

27 Roles and Responsibilities – Study Team vs. Sponsor/RSC 27 Safety monitoring by study team Acute on-site management and discussion with study team Periodic review by study team and monitoring committees Data generated by Data Management Centers (DMC) Expedited reporting to sponsor/RSC SAE sent to RSC RSC is not part of discussions that occur within study/safety monitoring teams regarding the event The RSC only has information about the event from the SAE Form; site should include relevant information from study team discussions RSC processes event and sends queries to site to obtain additional information All follow-up information should be provided to RSC

34 Documentation Differences Between AE CRF and SAE Form 34 Record in source document Record on AE case report form Yes Attach additional documentation Does AE meet SAE criteria?

35 Documentation Differences Between AE CRF and SAE Form: Data Elements 35

36 Safety Data from Clinical Trials Obligations to report safety data (IND or Non-IND studies): Data for non-expedited reporting: Recorded on AE CRF, goes to clinical trial database Data for expedited reporting: Recorded on AE CRF and then an SAE type form Goes to safety database (unless a linked system) IND timelines: 24 o to sponsor, 7/15 days to FDA, EMEA Post-marketing timelines: depends on sponsor, 15 days to FDA, EMEA Annual/Periodic Reports : Need safety data from clinical and safety database Must be reconciled 36

37 Stretch Break Stretch Break

38 Adverse Event ICH E2A: Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. 21 CFR Sep, 2011 Any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. 38

39 Adverse Event Term The AE should best describe what the subject says (i.e. verbatim description) Can be extracted from medical records Can incorporate medical assessment (including a diagnosis if available) The more accurate the AE term, the more accurate the safety database. The AE terms will be coded using a standard dictionary, e.g. Medical Dictionary for Regulatory Activities (MedDRA); this is NOT site responsibility 39

40 AE Term - Examples 40 If “anaphylactic reaction” is associated with “rash, dyspnea, hypotension, and laryngospasm,” report primary AE as “anaphylactic reaction.” If “myocardial infarction” is associated with “chest pain, dyspnea, diaphoresis, ECG changes and jaundice,” report “myocardial infarction” and “jaundice” as separate primary AEs.

41 Serious Adverse Event (SAE) A serious adverse event (experience) or reaction is any untoward medical occurrence that at any dose: Results in death, Is life-threatening Requires inpatient hospitalization or prolongation of existing hospitalization A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or a congenital anomaly/birth defect Is a congenital anomaly/birth defect Important medical events that may not result in death, be life- threatening, or require hospitalization may be considered serious when, based upon appropriate medical judgment, they may jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the outcomes listed in this definition 41 (ICH E2A, New Final Rule)

42 Suspected Adverse Reaction Adverse Reaction 21 CFR Sep, 2011  Suspected Adverse Reaction: Any adverse event for which there is a reasonable possibility that the drug caused the adverse event.  Adverse Reaction: Any adverse event caused by a drug Suspected adverse reaction implies a lesser degree of certainty about causality than adverse reaction 42

43 The Universe of Adverse Events 43 Adverse Events Suspected Adverse Reactions Adverse Reactions

44 Adverse Event vs. Event Outcome Hospitalization Hospitalization is a consequence and is not usually considered an AE. Example: If the subject was hospitalized due to congestive heart failure, “congestive heart failure” is the primary AE and hospitalization is the outcome. If the only information available is that the study subject was hospitalized, “hospitalization” can be reported. 44

45 Hospitalization Hospitalization in the absence of a medical AE is not in itself an AE and does not need to be reported in an expedited time frame, such as: Admission for treatment of a pre-existing condition (can include target disease) not associated with the development of a new AE or with a worsening of the pre-existing condition Diagnostic admission (e.g. for work-up of persistent existing condition such as pre-treatment lab abnormality) Protocol-specified admission (e.g. procedure required by study protocol) Administrative admission (e.g. for yearly physical exam) Social admission (e.g. study subject has no place to sleep) Elective admission (e.g. elective surgery) 45

46 Severity Describes the intensity of the event Events are graded on a severity scale Mild, Moderate, Severe Numeric Scale e.g. 1 to 5 Severity grading must match the clinical picture Presenting AE is Grade 1 AE progressed to SAE (hospitalization) The expedited report should have the grade of the SAE, not the AE 46

47 Seriousness is NOT the same as Severity

48 Action Taken with Drug Action Taken with Drug: Withdrawn Dose reduced Dose increased Dose not changed Unknown Not applicable > ICH E2B (R3) Refer to protocol Refer to DAERS 48

49 Outcome Outcome of reaction/event at the time of last observation Recovered/resolved Recovering/resolving Not recovered/not resolved Recovered/resolved with sequelae Fatal Unknown > ICH E2B (R3) Outcome of subject in study Remains in Study Withdrawn Lost to follow-up Death 49

50 Unexpected Adverse Event 21 CFR Sep, 2011 Considered unexpected if not listed in the IB or is not listed in the specificity or severity that has been observed; …… or is not consistent with the risk information described in the general investigational plan…. Hepatic necrosis vs. elevated hepatic enzymes (↑ severity) Cerebral thromboembolism vs. cerebral vascular accidents (specificity) Also… mentioned as occurring with a class of drugs or as anticipated from the pharmacological properties of the drug, but are not specifically mentioned with the particular drug under investigation 50

51 Causality 21 CFR Sep, 2011 For the purposes of IND safety reporting, “reasonable possibility” means that there is evidence to suggest a causal relationship between the drug and the adverse event ICH E2A Conveys that a “causal relationship” between the study product and the adverse event is “at least a reasonable possibility” Facts (evidence) exist to suggest the relationship Information on SAEs generally incomplete when first received Follow-up information actively pursued Judged by: Reporting health professional Sponsor 51

52 Examples of Reasonable Possibility Individual occurrence  a single occurrence of an event that is uncommon and known to be strongly associated with drug exposure 52 AngiodemaAnaphylaxis Hepatic InjuryBlood Dyscrasias Stevens-Johnson SyndromeRhabdomyolysis

53 Examples of Reasonable Possibility One or more occurrences  a single occurrence, or a small number of occurrences, of an event: (i) is not commonly associated with drug exposure (ii) is otherwise uncommon in the population exposed to the drug;  esp. if the event occurs in association with other factors strongly suggesting causation (e.g., strong temporal association, event recurs on rechallenge) 53 Tendon Rupture Heart Valve Lesions in young adults Intussusception in healthy infants

54 Examples of Reasonable Possibility Aggregate analysis of specific events  an analysis of events observed in a clinical trial that indicates those events occur more frequently in the drug treatment group than in a control group, e.g. i.known consequences of underlying disease ii.events common in study pop independent of drug therapy 54 i. non-acute death in a cancer trial ii. acute MI in a long-duration trial with an elderly population with cancer

55 Determination of Causality Standard determinations include: Is there [Drug Exposure] and [Temporal Association]? Is there [Dechallenge/Rechallenge] or [Dose Adjustments]? Any known association per [Investigator’s Brochure] or [Package Insert]? Is there [Biological Plausibility]? Any other possible [Etiology]? [More on this during case discussion on causality] 55

56 Comprehensive, stand-alone “medical story” Written in logical time sequence Include key information from supplementary records Include relevant autopsy or post-mortem findings Summarize all relevant clinical and related information, including: Study subject characteristics Therapy details Medical history Clinical course of the event(s) Diagnosis (workup, relevant tests/procedures, lab results) Other information that supports or refutes an AE Narrative 56 > ICH E2D

If Outcome is not resolved at time of evaluation, follow until resolution or stability at each study visit Is it [Expected]? Is it [Related]?

60 60 Sponsor role: (ICH E2D) Information about the case should be collected from the healthcare professionals who are directly involved in the study subject’s care Clearly identified evaluations by the sponsor are considered appropriate and are required by some regulatory authorities Opportunity to render another opinion; may be in disagreement with; and/or provide another alternative to the diagnosis/assessment given by initial reporter Sponsor makes an assessment of causality (attribution) just as the PI makes an assessment of causality (attribution) If causality (attribution) is different between the sponsor and the investigator, both assessments are reported Clinical Case Evaluation

62 Questions? 62

63 Appendix 63

64 1947: Nuremberg Code: Ten Directives for Human Experimentation 1.Voluntary consent of the human subject is absolutely essential: 2.The experiment must yield generalizable knowledge that could not be obtained in any other way and is not random and unnecessary in nature 3.Animal experimentation should precede human experimentation 4.All unnecessary physical and mental suffering and injury should be avoided 5.No experiment should be conducted if there is reason to believe that death or disabling injury will occur 6.The degree of risk to subjects should never exceed the humanitarian importance of the problem 7.Risks … should be minimized through proper preparations 8.Experiments … conducted by scientifically qualified investigators 9.Subjects … at liberty to withdraw from experiments 10.Investigators must be ready to end the experiment at any stage if there is cause to believe that continuing the experiment is likely to result in injury, disability or death to the subject 64

65 1948: Universal Declaration of Human Rights The UN General Assembly proclaims THIS UNIVERSAL DECLARATION OF HUMAN RIGHTS as a common standard of achievement for all peoples and all nations All human beings are born free and equal in dignity and rights Everyone has the right to life, liberty and security of person No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment 65

66 Statement of ethical principles to provide guidance to physicians and other participants in medical research involving human subjects Considerations related to the well-being of the human subject should take precedence over the interests of science and society Medical research subject to ethical standards that promote respect for all human beings and protect their health and rights Vulnerable populations need special protection Research Investigators should be aware of the ethical, legal and regulatory requirements for research on human subjects in their own countries as well as applicable international requirements Risks involved have been adequately assessed and can be satisfactorily managed Cease any investigation if risks found to outweigh potential benefits or if conclusive proof of positive and beneficial results 1964: Declaration of Helsinki: INTRODUCTION 66

67 Must conform to generally accepted scientific principles … thorough knowledge of the scientific literature, other relevant sources of information, adequate laboratory and … animal experimentation Design … experimental procedure should be clearly formulated in an experimental protocol. … submitted for consideration, approval to a specially appointed ethical review committee, … independent of the investigator, sponsor or any other kind of undue influence. The committee has the right to monitor ongoing trials Should be conducted only by scientifically qualified persons …. under supervision of a clinically competent medical person Participation by competent individuals as subjects must be voluntary 1964: Declaration of Helsinki: PRINCIPLES FOR ALL MEDICAL RESEARCH 67

68 Every precaution to protect privacy … and confidentiality of personal information … and to minimize the impact of the study on their physical, mental and social integrity Right to abstain from participation or to withdraw consent … at any time without reprisal. … obtain the subject's freely-given informed consent … in writing Both authors and publishers have ethical obligations. … preserve the accuracy of the results. Reports of experimentation not in accordance with principles of DoH should not be accepted for publication 1964: Declaration of Helsinki: PRINCIPLES FOR ALL MEDICAL RESEARCH 68

69 May combine medical research with medical care only to extent justified by its potential preventive, diagnostic or therapeutic value and … participation will not adversely affect the health of the patients who serve as research subjects. Benefits, risks, burdens and effectiveness of a new intervention must be tested against best current proven intervention, except in the following circumstances: Use of placebo, or no treatment, is acceptable where no current proven intervention exists; or For compelling and scientifically sound methodological reasons, placebo is necessary to determine efficacy or safety of an intervention –patients who receive placebo/no treatment will not be subject to any risk of serious or irreversible harm –extreme care to avoid abuse of this option 1964: Declaration of Helsinki: MEDICAL RESEARCH and MEDICAL CARE 69

70 : Declaration of Helsinki: MEDICAL RESEARCH and MEDICAL CARE At conclusion, patients are entitled to be informed about outcome of the study and to share any benefits that result from it, for example, access to interventions identified as beneficial in the study Refusal of a patient to participate or to withdraw from the study must never interfere with the patient-physician relationship

71 1966: International Covenant on Civil and Political Rights Adopted by UN General Assembly Article 7: No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment. In particular, no one shall be subjected without his free consent to medical or scientific experimentation 71

72 1979: The Belmont Report Issued by National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research Boundaries between research and practice 3 ethical principles for research: Respect for Persons Beneficence Justice Interests other than those of the subject may on some occasions be sufficient by themselves to justify the risks involved in the research, so long as the subjects’ rights have been protected 72

73 Respect for Persons Individuals should be treated as autonomous agents (capable of self determination) Persons with diminished autonomy deserve protection Application: Informed consent Beneficence Two general complementary rules: –Do not harm –Maximize possible benefits and minimize possible harms Application: Risk/Benefit assessment Justice Fairness in the distribution of the benefits and burdens of research Application: Fair procedures and outcomes in the selection of subjects : The Belmont Report

74 1982: International Ethical Guidelines For Biomedical Research Involving Human Subjects Prepared by the Council for International Organizations of Medical Sciences (CIOMS) Responsiveness to the health needs and priorities of the community Biomedical research with human subjects is to be distinguished from the practice of medicine, public health and other forms of health care, which is designed to contribute directly to the health of individuals or communities 2002 Revision: Ethical justification & scientific validity (#1), Ethical review (#2-3) Informed consent (#4-6), Inducement to Participate (#7) Benefits and Risks (#8) Choice of control (#10) Equitable distribution of burdens and benefits (#12) Special pops: vulnerable, children, incapable of consent, women, pregnant women (#13-17) Right of injured subjects to treatment and compensation (#19) Obligation of external sponsors to provide health care services (#21) 74

75 1995: Guidelines for Good Clinical Practice (GCP) for Trials on Pharmaceutical Products GCP Definition: (globally applicable) standard for clinical studies encompasses the design, conduct, monitoring, termination, audit, analyses, reporting and documentation of the studies ensures studies are scientifically and ethically sound clinical properties of the pharmaceutical product (diagnostic, therapeutic or prophylactic) under investigation are properly documented Guidelines developed by WHO in consultation with national drug regulatory authorities within WHO’s Member States Handbook for Good Clinical Research Practice (GCP) as an adjunct to Guidelines Adopted by International Conference on Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use 75

76 Compliance with this standard provides public assurance that: The rights, safety, and well-being of trial subjects are protected, consistent with the principles that have their origin in the Declaration of Helsinki Clinical data are credible Facilitates mutual acceptance of clinical data internationally among regulatory authorities in participating regions Defines specific responsibilities: Institutional Review Boards/Independent Ethics Committees Investigators Sponsors Monitors 1995: Guidelines for Good Clinical Practice (GCP) for Trials on Pharmaceutical Products 76
