All assumptions and business rules described in the SDTMIG QS domain are applicable to this supplement. Additional assumptions specific to the PRO-CTCAE V1.0 are listed below.

The PRO-CTCAE V1.0measurement system is a patient-reported outcome (PRO) instrument developed to capture symptomatic adverse events of patients in cancer clinical trials. The PRO-CTCAE V1.0 was designed to be used in conjunction with the Common Terminology Criteria for Adverse Events (CTCAE).[1] It consists of an item library rather than a static/fixed question item type of instrument. You should This item library concept is different than other CDISC public domain and copyrighted specific QRS instruments. Users are directed to use the form builder as described on the PRO-CTCAE website to build CRFs and with instructions provided by NCI to select the items to implement it in your a clinical study. The PRO-CTCAE V1.0 includes multiple choice questions on the frequency, severity, interference, presence/absence and/or amount of specific adverse events.

Administration of PRO-CTCAE V1.0 may be conducted via different modes, including screen-based, interactive voice response, and paper. Electronic implementation of the PRO-CTCAE V1.0 instrument is measurement system is recommended by NCI/NIH.

1. As a CDISC QRS standard, the instrument supplement name is PRO-CTCAE V1.0, as provided in this supplementdocument. 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 users responsibility to identify the subset of items used from the overall PRO-CTCAE V1.0 Item Library (Version 1.0). The subsetted PRO-CTCAE V1.0 user's instrument should 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 instrument from measurement system from the overall PRO-CTCAE V1.0.

2. For the PRO-CTCAE V1.0, QSORRES is populated represented with the text description while the numeric rating is represented in the standardized character and numeric result variables QSSTRESC and QSSTRESN. Please reference 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 AE being measured, items assessing symptom presence/absence are rated as follows:
      1. Items assessing symptom presence/absence are rated on a binary response scale and rated from 0-1 (e.g., 0 = “No” and 1 = “Yes”);
      2. Items rated on multiple (more than two) response scale and rated from 0-1 (e.g., 0 = “No”, 1 = “Yes”, and “Not applicable” or "Not Applicable"); or);
   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”, Not applicable)
   4. Items assessing symptom interference Items assessing symptom amount 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 frequency amount are rated on a 5-point scale and are rated from 0-4 (e.g., 0 = “Never”“Not at all”, 1 = “Rarely”“A little bit”, 2 = “Occasionally”“Somewhat”, 3 = “Frequently”“Quite a bit”, and 4 = “Almost constantly”“Very much”).
   6. QSTESTCD = "PT01066A " to "PT01071A" have specific responses .
      1. QSTESTCD=PT01069A and QSTESTCD=PT01070A assessing symptom presence/absence are rated on multiple (more than two) response scale and rated from 0-1 (e.g., 0 = “No”, 1 = “Yes”, “Not sexually active”, and “Prefer not to answer”).

      2. QSTESTCD=PT01066A, PT01068A, and PT01071A 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”, “Not applicable”, "Not sexually active", and “Prefer not to answer”).

      3. QSTESTCD = "PT01067A" assessing symptom frequency is rated on a 5-point scale rated from 0-4 (e.g., 0 = “Never”, 1 = “Rarely”, 2 = “Occasionally”, 3 = “Frequently”, and 4 = “Almost constantly”, "Not sexually active", and “Prefer not to answer”).
   7. 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”).
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" thru "PT0191A") and severity of the symptom at its worst (QSTESTCDs "PT01082B" thru "PT0191B").
4. Total 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 reference 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 Item Library (Version 1.0). The exception to this is the solicited verbatim symptom terms with QNAM = "OTHER SYMPTOMS".

7. Electronic conditional branching is recommended by NCI/NIH in the conduct of the PRO-CTCAE V1.0 for symptom terms that have two or more items. The logic branches from frequency, then to severity, then to interference. For example, if frequency is > (greater than) never, you next pose the severity question, and if severity>none, you pose the interference question. Please reference the PRO-CTCAE website for more details on the electronic conditional branching approach. In the conduct of the PRO-CTCAE V1.0 it expects responses for each item and there should be no missing responses. Electronic branched severity items are assigned responses of 0 = "None" and electronic branched interference items are assigned 0 = "Not al all".

8. The language in which the PRO-CTCAE V1.0 was administered (e.g., English, Spanish, Japanese) is collected with the Form Builder application and may be represented as a supplemental qualifier with QNAM = "QSDCLANGQSLANGDC". Reference the PRO-CTCAE V1.0 website for a list of available language translations.
9. Terminology

   1. QSCAT, QSTESTCD, and QSTEST values are included in CDISC Controlled Terminology.

   2. A full list of value sets for the qualifier, and result fields is provided in Section 4, SDTM Mapping Strategy.

...

The PRO-CTCAE V1.0 example below shows the terminology used to implement the instrument in measurement system in the QS domain. This example shows the data for 1 subject collected at the baseline visit for a PRO-CTCAE V1.0 instrument. The example uses CDISC Controlled Terminology for QSTESTCD, QSTEST, and QSCAT. All original results, matching the CRF item response text, are represented in QSORRES.This result is then represented as a standard numeric score in QSSTRESN and as a standard character representation in QSSTRESC.

...

The table represents the items from the PRO-CTCAE V1.0 instrument measurement system.

This section is used for reference regarding the CRF data capture and to understand the alignment of the instrument to measurement system to the SDTM QS domain. It also provides guidance on how the result variables (QSORRES, QSSTRESC, and QSSTRESN) should be populated.
