Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Background and History

Why is NCI stressing requirements for accurate, specific AE documentation and reporting?

  • It is the law – Federal Regulations

  • Required of all physicians who signthe FDA1572 investigator registration form

  • Ensures human subject safety

  • Facilitates accurate analysis of effects from investigational cancer interventions

History of the Common Toxicity Criteria (CTC)

Since 1982, NCI CTC has been the standard for AE reporting in the oncology community.

Historical Timeline

1982

  • Adverse Drug Experience Reporting

  • Study Summaries

  • IND reports to FDA

  • Publications

  • Format:

    • 18 CATEGORIES

    • 49 AE Terms

    • Grades:

      • Grade 1 = Mild

      • Grade 2 = Moderate

      • Grade 3 = Severe

      • Grade 4 = Life-threatening


Slide6 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Background and History - continued

1997 -CTC Review Committee assembled to revise and expand CTC.

1998 - Introduced CTC v2.0

  • 24 CATEGORIES

  • ~300 AE Terms (Acute)

  • Specificity

  • Radiotherapy

  • Pediatrics

  • Appendices

    • RTOG/EORTG Late Radiation Morbidity Scoring Scheme

    • BMT Complex/Multi-component Event Scheme

NCI CTC v2.0 has become the worldwide standard dictionary for reporting acute AEs in cancer clinical trials and has been translated into several languages – NCI and Industry.


Slide7 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Background and History - continued

2002 -CTEP convened a CTC Development Team (CTCDT) consisting of independent disease and modality-specific cancer therapy experts and NCI representatives to oversee the creation of the Common Terminology Criteria Adverse Event (CTCAE) v3.0.

  • Update core criteria.

  • Expand to create comprehensive dictionary of AEs and grades applicable to all oncology clinical trials without regard to:

    • Chronicity

    • Modality

  • For criteria development, CTEP coordinated:

    • Late effects

    • Surgical

    • Pediatric workshops

  • CTCAE v3.0 is the first uniform and comprehensive dictionary of AE grading criteria available for use by all modalities.

    2003 -Introduced CTCAE v3.0.

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events

Multiple clinical terms are used to convey the occurrence of an Adverse Event (AE):

  • Side effect

  • Acute effect or late effect

  • Complication

  • Toxicity

  • Morbidity, etc.

All terms essentially point to a change possibly caused by treatment.


Slide9 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

  • An AE is any unfavorable or unintended:

    • Sign

    • Abnormal lab

    • Symptom

    • Disease

  • An AE is a unique representation of a specific event used for medical documentation and scientific analyses.

  • Each AE term is mapped to a MedDRA v6.0 term and code.

    • Same term and code used in Japan and the EU.

  • AEs can be:

    • Symptomatic or completely asymptomatic.

    • Clinically or radiographically detected.

    • Noted on laboratory studies or other testing.


Slide10 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

What to report as an AE

  • The guideline for clinicians is to capture any effect from an intervention which may be deleterious.

  • Prudent adverse event reporting requires that only AEs that are mandated in protocols and clinically relevantpositives be documented.


Slide11 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

There are multiple causes of AEs:

  • Pre-existing conditions

    • Hypertension

    • Diabetes

  • Concomitant medications

    • Anticoagulants

    • Steroids

  • Other causes

    • Transfusion reactions

    • Accidental injuries

  • Reporting and grading an AE simply reports that an event occurred and the seriousness of the event.

  • The clinician must assign attribution of the event, either to the intervention or something else.


Slide12 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

Physician Responsibilities in Clinical Research

  • Must become familiar with the CTCAE Terms and Grades.

  • Responsible for documenting AEs that can be verified on audit.

  • Must document signs, symptoms, clinical findings, etc. as they appear.

  • Note: Realize documentation of AEs does not necessarily imply causality to intervention or error in administration.


Slide13 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

Physician Responsibility Regarding Grade

  • Document at least descriptive terms found in definitions of Grades to enable CRAs easy identification of numeric Grade.

  • Document signs, symptoms, objective measures that characterize severity (Grade).

Refer to CTCAE descriptions of Grade.


Slide14 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

Documenting Grade

  • Semi-colon indicates ‘or’ within the description of the Grade.

  • Em dash (—) indicates a Grade not applicable to the AE.

In the development of CTC/CTCAE careful consideration was given to including all descriptions of events that were considered “serious” or “life-threatening” (as defined in the FDA regulations) in Grade 3 and 4, respectively.


Slide15 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

Documenting Grade

  • A patient need notexhibit all elements of a Grade description to be designated that Grade.

    • Example:

    • Induration/fibrosis (skin and subcutaneous tissue)

    • Grade 3:

    • Dysfunction interfering with ADL; very marked density, retraction or fixation

      Read as “Dysfunction ….. OR very marked……”

    • Interpretation:

    • A patient with very marked density, retraction or fixation, but is able to perform ADLs, is Graded 3.

When a patient exhibits elements of multiple Grades, the highestGrade is to be assigned.


Slide16 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

Physician Responsibility Regarding Attribution

  • Physicians are to document the relationship (ATTRIBUTION) of the protocol intervention to each event.

  • Designating an event as treatment related (or not) is done two ways:

    • 1. By the treating CLINICIAN:

      • Formal “assignment” per adverse event reporting form (“...unlikely, possibly, etc) at the time of clinical evaluation.

    • 2. By Investigators:

      • Later in aggregate data review and reporting by the Investigators.


Slide17 l.jpg

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

Adverse Events - continued

Attribution Standards

  • Unrelated:

    The Adverse Event is clearly not related to the investigational agent(s)

  • Unlikely:

    The Adverse Event is doubtfully related to the investigational agent(s)

  • Possible:

    The Adverse Event may be related to the investigational agent(s)

  • Probable:

    The Adverse Event is likely related to the investigational agent(s)

  • Definite:

    The Adverse Event is clearly related to the investigational agent(s)

Responsible Adverse Event (AE) Reporting: Finding Appropriate AE Terms

How and When to use the ‘Other, Specify’ Mechanism for AE Reporting

  • In recognition that as science and cancer treatments continue to evolve and the potential for novel and unknown untoward affects to occur, the NCI has incorporated a mechanism into the CTC and CTCAE to capture these yet-to-be-defined events.

  • In the rare event that a suitable CTC or CTCAE term cannot be found, the NCI allows the submitter to report the appropriate verbatim term via the ‘Other, Specify’ mechanism.

  • The use of the ‘Other, Specify' mechanism is an exception, not the rule.

    • To minimize overuse, CTEP, NCI will build rules into applications to flag and/or reject reports that take excessive advantage of the ‘Other, Specify’ mechanism. In addition, CTEP, NCI will closely scrutinize all AEs submitted as ‘Other, Specify’. The investigator will be required to correct and resubmit their report if a suitable CTC or CTCAE term is identified by CTEP, NCI staff.


  • Slide37 l.jpg

    How and When to use the ‘Other, Specify’ Mechanism for AE Reporting - continued

    Using the ‘Other, Specify’ Mechanism

    • If a suitable CTC or CTCAE term is not available, the investigator must make a note to this affect in the source documentation.

    • The investigator must identify the most appropriate CTC or CTCAE CATEGORY to classify the event.

    • Within each CATEGORY is a CTC or CTCAE term ‘Other’ (i.e., ‘Cardiac Arrhythmia – Other’). The submitter must describe or ‘specify’ what the adverse event was. Descriptions must be explicit and provide sufficient detail to describe the event and should be as brief as possible (for example, two to four words).

    • Once the CTC or CTCAE CATEGORY ‘Other’ term has been selected and specified, the submitter must ‘Grade’ the event. The grade refers to the severity of the event. The general description of grades to be used for the ‘Other; Specify’ mechanism are as follows:

      • Grade 1 – Mild AE

      • Grade 2 – Moderate AE

      • Grade 3 – Severe AE

      • Grade 4 – Life threatening or disabling AE

      • Grade 5 – Death related to AE

    For more information, see the Guidelines for CTC/CTCAE ‘Other, Specify’ from the CTC/CTCAE Home Page.

    Summary: Using CTC v2.0/CTCAE v3.0

    • Use CTC v2.0 or CTCAE v3.0 to locate appropriate AE term.

    • Document the grade of the AE.

      • If a patient exhibits elements of multiple grades, assign the highest grade.

    • Assign attribution of the AE.

    • If a CTC or CTCAE term cannot be found using the different tools available, the ‘Other, Specify’ option should be used.

      • Grade and attribution must be assigned.
