Title: Safety Workshop


1
Safety Workshop
  • Ling Chin, MD, MPH
  • Safety Pharmacovigilance Team,
  • OPCRO, DAIDS, NIAID

2
Objectives
  • At the conclusion of this workshop, participants
    will be able to demonstrate an understanding of
  • 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

3
Objectives
  • At the conclusion of this workshop, participants
    will be able to demonstrate an understanding of
  • Ensuring 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 (attribution)

4
Current FDAAA Environment
  • 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
  • New authorities to require postmarket studies and
    clinical trials, safety labeling changes, and
    Risk Evaluation and Mitigation Strategies (REMS)
  • Increased activities for active post market risk
    identification and analysis
  • New reporting of adverse events related to food
    and new regulations for pet food labeling,
    ingredients, and processing standards

5
Current FDAAA Environment
  • FDAAA Implementation Examples
  • Required postmarketing studies, or clinical
    trials to address safety issues (21 letters)
    postmarketing commitments now required
    (previously voluntary) and established timeframes
    are enforceable
  • Required safety label changes (4 times)
  • Can require REMS to ensure that the benefits of a
    drug outweigh its risks (13 REMS)
  • Sentinel Initiative (launched May 08)
  • Create and implement a nation-wide active,
    electronic surveillance system for monitoring
    medical product safety
  • Develop methods to obtain access to disparate
    data sources and to establish a postmarket risk
    identification and analysis system
  • Requires FDA to work closely with partners from
    public, academic, and private entities

6
Framing the context
  • Impact relevant to DAIDS
  • When DAIDS holds the Investigational New Drug
    (IND) increased requirements for safety
    assessment, pharmacovigilance, risk evaluation
  • Clinical Trial Agreements (CTAs ) with
    pharmaceutical companies
  • Increasing demands for safety data and safety
    reports, increasingly shortened timelines
  • Postmarketing requirements on Marketing
    Authorizing Holders (MAHs) irrespective of DAIDS
    obligations for IND studies vs. non-IND studies
    expect final safety reports in 15 days or less

7
Framing the context
  • Impact relevant to pharmaceutical companies
  • Increased requirements for safety assessment,
    pharmacovigilance, risk evaluation, and risk
    mitigation/ minimization
  • Parallel and additional requirements may be
    required by other authorities globally, including
    European Medicine Evaluation Agency (EMEA)
  • FDA can penalize pharmaceutical companies for a
    variety of noncompliance issues
  • Civil monetary penalties (CMPs) can be assessed
    for an assortment of violations such as
    violations of new REMS provisions, postmarket
    study requirements, or labeling violation
  • CMPs can reach substantial amounts, e.g. maximum
    of 10 million in a single proceeding

8
Framing the context
  • Increasing demands for safety data
  • All Serious Adverse Events (SAEs)
  • Follow all AEs/SAEs till resolved or stable
  • Additional adverse events of interest
  • Cancers
  • Myocardial Infarctions (MIs)
  • Hepatic events
  • Pregnancy outcomes
  • Global reporting to EMEA and regulatory agencies
    of European Union (EU) member states
  • Use of CIOMS form
  • Country of origin of AE

Safety Monitoring
  • Why is safety monitoring required in all clinical
    trials?
  • To ensure Subject Safety and Study Integrity

Purpose of Safety Monitoring
14
Clinical Role vs. Research RoleBalancing Both
Roles
  • Clinical Role Subject OK
  • Research Role Study/Data OK
  • Is subject in imminent jeopardy?
  • Provide appropriate management commensurate with
    clinical situation, e.g. toxicity management
  • Provide appropriate referral emergent care or
    back to regular care
  • Follow up with subject status
  • Not Subjects Primary Clinician
  • Identification of adverse event
  • Immediate notification necessary? To whom? per
    protocol and safety monitoring plans
  • Complete documentation of adverse event. Follow
    until resolution/stability including updating
    records
  • Determine if AE meets criteria for SAE/EAE
  • Adhere to reporting requirements
  • Adhere to toxicity management as specified
  • Adhere to stopping rules as specified

Assurance of Safety and Well-BeingResearch vs.
Medical Roles
  • 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
  • Therapeutic misconception
  • Subjects think they are receiving proven
    interventions, per their usual clinical care,
    despite being in a research study
  • Physicians think they can provide interventions,
    per usual practice

18
Roles and Responsibilities Study
Clinician/Physician
19
Roles and Responsibilities Study Team
20
Roles and Responsibilities Study Team vs.
Sponsor/RCC
  • 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/RCC
  • SAE/EAE sent to RCC
  • RCC is not part of discussions that occur within
    study/safety monitoring teams regarding the event
  • The RCC only has information about the event from
    the EAE Form site should include relevant
    information from study team discussions
  • RCC processes event and sends queries to site to
    obtain additional information
  • All follow-up information should be provided to
    RCC

Drug Development ModelSafety Data Flow in
Clinical Trials
25
Safety Data from Clinical Trials
  • Obligations to report data from DAIDS clinical
    trials irrespective of IND status. For both 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 linked to an SAE type form
  • goes to safety database
  • IND timelines 24o 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

26
Adverse Event Flowchart
27
Adverse Event
  • Protocol specifications for AE
  • When to collect e.g., study visit
  • Method of collection e.g., in person, telephone
    call
  • What to collect e.g., all AEs, only certain AEs
    by body system, only certain AEs by severity
  • What forms to use e.g. AE CRF, study CRFs
  • Protocol specifications for SAE/EAE
  • Criteria
  • Expedited time frames
  • Form e.g. SAE, EAE form

28
Documentation Differences Between AE CRF and
SAE/EAE Form

Documentation Differences Between AE CRF and
SAE/EAE Form Data Elements
  • AE CRF
  • Data Elements
  • SAE/EAE Form
  • Data Elements
  • AE
  • Start Date
  • Start Date / Continuing
  • Is it SAE?
  • Severity
  • Relatedness
  • Action taken with Study Agent
  • Outcome (study participation)
  • Participant Identifiers
  • Study Agent details
  • Narrative
  • Past medical history
  • Relevant labs, tests, procedures
  • Concomitant meds
  • Outcome of SAE/EAE
  • Other supporting information

31
Adverse Event
  • 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.
  • (ICH E2A)

32
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

33
AE Term - Examples
  • If anaphylactic reaction is reported with
    rash, dyspnea, hypotension, and laryngospasm,
    selecting anaphylactic reaction alone is
    considered appropriate.
  • If myocardial infarction is reported with
    chest pain, dyspnea, diaphoresis, ECG changes
    and jaundice, it would be considered appropriate
    to select terms for both myocardial infarction
    and jaundice.
  • EAE Form List only one primary AE. Choose the
    one term that best describes the nature of the
    adverse event being reported.

34
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,
  • Results in persistent or significant
    disability/incapacity, or
  • Is a congenital anomaly/birth defect.
  • In addition, important medical events that may
    not be immediately life-threatening or result in
    death or hospitalization but may jeopardize the
    patient or may require intervention to prevent
    one of the other outcomes listed in the
    definition aboveshould also usually be
    considered serious.
  • (ICH E2A)   

35
Adverse Event vs. Event Outcome
  • Death
  • Death is an outcome and is not usually considered
    to be an AE.
  • Example If death due to myocardial infarction
    is reported, myocardial infarction can be
    selected and death should be captured as the
    outcome.
  • If the only information reported is death, then
    the most specific death term available should be
    selected.
  • Example If a reporter states only that a study
    subject was found dead, found dead can be
    selected.

36
Adverse Event vs. Event Outcome
  • Hospitalization
  • Hospitalization is a consequence and is not
    usually considered an AE.
  • Example If hospitalization due to congestive
    heart failure is reported, congestive heart
    failure can be selected and hospitalization
    should be captured as the consequence of the
    event.
  • If the only information reported is the outcome
    term, then the most specific term available
    should be selected.
  • Example If a reporter states only that a study
    subject was hospitalized, hospitalization can
    be selected.

37
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.
  • 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
    existing condition persistent 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)

38
Severity
  • Describes the intensity of the event
  • Events are graded on a severity scale
  • Example
  • Mild, Moderate, Severe
  • Numeric Scale e.g. 1 to 5

39
Severity vs. Serious
  • Severity is not the same as Serious
  • Severity Intensity
  • e.g., chest pain, moderate severity
  • Serious (SAE) Based on patient/event outcome or
    action criteria
  • Used to define regulatory reporting obligations
  • AE classification must divorce usage of serious
    in a clinical sense from serious in a regulatory
    sense
  • For clinical connotations, use severity
    descriptors

40
Action Taken with Drug
  • Action Taken with Drug
  • Withdrawn
  • Dose reduced
  • Dose increased
  • Dose not changed
  • Unknown
  • Not applicable
  • Refer to protocol
  • Refer to DAIDS EAE Form
  • gt ICH E2B (R3)

41
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
  • Outcome of subject in study
  • Remains in Study
  • Withdrawn
  • Lost to follow-up
  • Death

42
Expectedness
  • Pertains to whether an event is expected or
    unexpected (on the basis of previous observation,
    not what might be anticipated from the
    pharmacological properties of the product)
  • Unexpected the nature or severity of the adverse
    event is not consistent with the applicable
    product information (e.g. Investigators Brochure
    for unapproved product, Package Insert for
    approved product)

43
Relatedness (Causality)
  • No standard international nomenclature
  • Conveys that a causal relationship between the
    study product and the adverse event is at least
    a reasonable possibility ICH E2A
  • Facts (evidence) exist to suggest the
    relationship
  • Information on SAEs/EAEs generally incomplete
    when first received
  • Follow-up information actively pursued
  • Judged by
  • Reporting health professional
  • Sponsor

44
Determination of Relatedness
  • Standard determinations include
  • Is there Drug Exposure and Temporal
    Association?
  • Is there Dechallenge/Rechallenge or Dose
    Adjustments?
  • Any known association per Investigators
    Brochure or Package Insert?
  • Is there Biological Plausibility?
  • Any other possible Etiology?

45
Determination of Relatedness
  • May be more art than science
  • 1st level of review NR
  • 2nd level of review any degree R
  • 3rd level of review any evidence to compel
    moving in one direction or the other i.e. from
    NR to any reasonable possibility of R, or from
    any R to NR
  • Clear-cut case easy to make a determination
  • Not so clear-cut use your best judgment based
    on available information assure adequacy of
    information obtain more whenever
  • Unless clear-cut case, theres no absolute right
    or wrong give your best judgment substantiate
    and follow-up
  • Err on conservative side contribute to knowledge
    base

46
Narrative
  • 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
  • gt ICH E2D

46
47
Narrative Template
  • This is a Age year old Race Male/Female in
    Study who reported Primary AE on Date of
    AE. Enrolled into study on Date Enrolled,
    Study medication was started on Date, which is
    Study Day _/Week _, taken for Duration. The
    event occurred during the Treatment/Follow-up
    Phase.
  • If fetus provide Gestational Age, (or mothers
    LMP), at time of event. Also, Gestational
    Age/Trimester at first drug exposure and
    duration of exposure. If birth, provide details
    of Infant Status at birth. If hospital stay is
    complicated, provide details of hospital stay.
  • Provide details of the AE in chronological
    order, along with other Signs/Symptoms. Provide
    details of Physical Exam, along with all
    relevant Procedures and Lab Results.

47
48
Narrative Template
  • Provide details of Treatment and Treatment
    Rationale on basis of Findings/Test Result(s).
    Describe Treatment Response.
  • If hospitalization, provide Dates
    Hospitalization, describe relevant Hospital
    Course, Diagnostic Work-up, Procedures/Tests
    and Results, Treatment, Treatment Response.
  • Provide Discharge Diagnosis, and any Follow-up
    Information. List Discharge Meds.
  • Provide pertinent Past Medical Hx, Family Hx,
    Concomitant Meds, Alcohol/Tobacco/Substance
    Use and any previous similar AEs.

48
49
Review and Assessment of SAE/EAE
  • Assemble all information available and use
    medical judgment
  • Standard for each AE
  • Select Seriousness Criteria
  • Grade Severity per DAIDS Toxicity Table
  • Specify Actions Taken on Study Product
  • Specify Outcome of SAE/EAE. If Outcome is not
    resolved at time of evaluation, follow until
    resolution or stability at each study visit
  • Is it Expected?
  • Is it Related?

49
50
Clinical Case Evaluation
  • Sponsor role (ICH E2D)
  • Information about the case should be collected
    from the healthcare professionals who are
    directly involved in the study subjects 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
