  1. As a CDISC QRS standard, the supplement name is PRO-CTCAE V1.0, as provided in this document. As an item library, sponsors may select items from the overall library as a subset of items with the same CDISC Controlled Terminology as appropriate for the condition being studied. It is the user's responsibility to identify the subset of items used from the overall PRO-CTCAE V1.0 Quick Guide to the Item Library V1.0. The subsetted PRO-CTCAE V1.0 user's measurement system should be titled "PRO-CTCAE sponsor-specified symptoms..." based on the sponsor's discretion when they identify the specific items being used. This will distinctly describe the subsetted measurement system from the overall PRO-CTCAE V1.0. The  The form builder does not represent the Quick Guide to the Item Library V1.0 symptom term when creating forms with selected symptoms, due to different language interpretations. Users need to reference the full language annotated Item Library v1.0 form to obtain the related symptom term for forms based on selected symptoms. 

  2. For the PRO-CTCAE V1.0, QSORRES is represented with the text description; the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN. Please see the PRO-CTCAE website FAQs for more details on the numeric responses. The responses for the PRO-CTCAE V1.0 are as follows:

    1. Depending on the symptomatic adverse event (AE) being measured, items assessing symptom presence/absence are rated as follows:
      1. Items rated on a binary response scale and rated from 1-0 (e.g., 1 = “Yes” and 0 = “No”)
      2. Items rated on a multiple (more than 2) response scale and rated from 1-0 (e.g., 1 = “Yes”, 0 = “No”, and “Not applicable”)
    2. Items assessing symptom frequency are rated on a 5-point scale and are rated from 0-4 (e.g., 0 = “Never”, 1 = “Rarely”, 2 = “Occasionally”, 3 = “Frequently”, and 4 = “Almost constantly”).
    3. Items assessing symptom severity are rated on a 5-point scale rated from 0-4 (e.g., 0 = “None”, 1 = “Mild”, 2 = “Moderate”, 3 = “Severe”, and 4 = “Very severe”).
      1. QSTESTCD=PT01036A assessing symptom severity is rated on a 5-point scale rated from 0-4 (e.g., 0 = “None”, 1 = “Mild”, 2 = “Moderate”, 3 = “Severe”, and 4 = “Very severe”, and "Not applicable")
    4. Items assessing symptom interference are rated on a 5-point scale and are rated from 0-4 (e.g., 0 = “Not at all”, 1 = “A little bit”, 2 = “Somewhat”, 3 = “Quite a bit”, and 4 = “Very much”).
    5. Items assessing symptom amount are rated on a 5-point scale and rated from 0-4 (e.g., 0 = “Not at all”, 1 = “A little bit”, 2 = “Somewhat”, 3 = “Quite a bit”, and 4 = “Very much”).
    6. QSTESTCD = "PT01066A " to "PT01071A" sexual symptoms have specific responses .
      1. QSTESTCD=PT01069A and QSTESTCD=PT01070A assessing sexual symptom presence/absence are rated on multiple (more than 2) response scale and rated from 1-0 (e.g., 1 = “Yes” and 0 = “No”, “Not sexually active”, and “Prefer not to answer”).

      2. QSTESTCD=PT01066A, PT01068A, and PT01071A assessing sexual symptom severity are rated on a 5-point scale rated from 0-4 (e.g., 0 = “None”, 1 = “Mild”, 2 = “Moderate”, 3 = “Severe”, and 4 = “Very severe”, "Not sexually active", and “Prefer not to answer”).

      3. QSTESTCD = "PT01067A" assessing sexual symptom frequency is rated on a 5-point scale rated from 0-4 (e.g., 0 = “Never”, 1 = “Rarely”, 2 = “Occasionally”, 3 = “Frequently”, 4 = “Almost constantly”, "Not sexually active", and “Prefer not to answer”).
  3. The CRF represents up to 5 "other symptoms" to be recorded. In discussions with NIH, it was agreed to provide up to 10 "other symptoms" to be recorded if they existed. QSTESTCDs (QSTESTCDs "PT01082A" through "PT01091A") and severity of the symptom at its worst (QSTESTCDs "PT01082B" through "PT01091B").
  4. PRO-CTCAE V1.0 total scoring instructions have not yet been developed. Item-level scores are not combined (i.e., no total score nor symptom-specific scores are calculated).
  5. The time period of evaluation for the PRO-CTCAE V1.0 is populated in the QSEVLINT field in ISO 8601 format when the evaluation interval can be precisely described as duration. The evaluation interval for the PRO-CTCAE V1.0 is the past 7 days (QSEVLINT = "-P7D". Please see the PRO-CTCAE website for more details on the evaluation interval.
  6. Items are divided into 15 subcategories represented in the QSSCAT variable. These categorizations represent how the symptom terms are categorized in the PRO-CTCAE V1.0 Item Library (Version 1.0). See Section 4, SDTM Mapping Strategy, for a list of these subcategory values. 
    1. The symptomatic AE being measured by a given item (e.g., the Symptom Term represented on the CRF corresponding to a given item) is stored in the SUPPQS dataset with the QNAM = "QSSYMPTM". This matches the symptom term identified in the PRO-CTCAE V1.0 Quick Guide guide to the Item Library V1.0. The exception to this is the solicited verbatim symptom terms QSTESTCD = "PT01081 to PT01091B"with QNAM = "OTHER SYMPTOMS".

  7. Conditional branching is recommended by NCI/NIH in the conduct of the electronic version of the PRO-CTCAE V1.0 for symptom terms that have 2 or more items. The logic branches from frequency, then to severity, then to interference. For example, if frequency is > (greater than) never, next pose the severity question, and if severity > none, pose the interference question. Please see the PRO-CTCAE website for more details on the electronic conditional branching approach.

    1. When a paper version is administered, conditional branching does not apply.

  8. Some items on the PRO-CTCAE may be not done due to conditional branching per the electronic instrument instructions as described in assumption 7. A record is created with the assigned responses based on the PRO-CTCAE V1.0 website FAQ and a QS supplemental qualifier variable is used to indicate an item was conditionally branched. Per NIH, these items are assigned values as follows: severity items are assigned responses of "None" and 0; interference items are assigned "Not at all" and 0. When an item is not done due to conditional branching, it is represented as follows:
