This process creates a disease response swimmer plot and tables around either the best or last recorded response rates and calculated objective response rate for solid tumor oncology clinical trials, representing RECIST evaluation from the
RS domain. The output includes a swimmer plot for subjects who have responded favorably to treatment for solid lesion trials per
RECIST criteria using CDISC recommended evaluation responses of Complete Response (
CR), and Partial Response (
PR). Optionally, subjects can be annotated with responses of Stable Disease (SD) and/or Progressive Disease (PD) as well. The results of these assessments are summarized based on selecting either the
Best response per subject, based on preferred order:
CR,
PR,
SD,
PD for controlled terms, respectively, or
Last recorded response. Using this summarized response, subject counts and percentages of response rates are displayed in a summary table split by Treatment Variable based on report selection. The objective response rate (the sum and percentage of subjects who had
CR +
PR assessment result) is also calculated and listed in the summary table.
Running this report for a modified Nicardipine study using default settings generates the report shown below. The Include Stable Disease and Include Progressive Disease Response options were checked.
This table lists the numbers of the subjects showing complete response (CR) and partial response (
PR), as well as those with stable disease (
SD) for each treatment. Subjects showing progressive disease (PD) as their best response would also be listed. The table also shows the overall response rate (
CR + PR) for each treatment. Total subject counts are also displayed.
Available variables include Planned, which is selected when the treatments patients received exactly match what was planned and
Actual, which is selected when treatment deviates from what was planned.
You can also specify a variable other than the ARM or
TRTxxP (planned treatment) or
ACTARM or
TRTxxA (actual treatment) from the CDISC models as a surrogate variable to serve as a comparator.
Use the Disease Response Test for Analysis option to select the relevant test code (
RSTESTCD) whose results (
RSSTRESC) contain values for tracking response assessment of
Complete Response,
Partial Response,
Progressive Disease, or
Stable Disease across study visits/time points. By default, if this option is left blank the report will attempt to find and use an
RSTEST value of
OVERALL RESPONSE (case insensitive).
Use the Category for Response Assessment Criteria Identification option to filter/select to the specific response assessment criteria value to use for showing response assessment in the resulting swimmer plot and table. If this field is left blank or your data does not contain the expected variable RSCAT with valid values of criteria identification, all records will be considered for the given selected test or algorithmically for any test named
OVERALL RESPONSE.
You must specify the end date for collecting data to assess response of patients to the treatments. The End Date Variable to Use for Subject Duration option is used to select which variable date reference from the demography domain to use for calculating the response duration. The
Subject Reference End Date is chosen by default.
Use the Calculate Overall Response Rate as to select the option for which to calculate Response Rate Summaries displayed in the table for each subject. Choose
Best to select a representative response that indicates the best response a patient had recorded at any time during response assessment using preferential logic of
CR,
PR,
SD,
PD order. Choose
Last to take the last response assessment recorded for each subject.
Note: If multiple responses are observed at the final visit, the best among them is reported.
If there is a supplemental domain (SUPPXX) associated with your study, you can opt to merge the non-standard data contained therein into your data.
Use the Duration Time Scale to Plot on X-Axis option to select the time unit scale (
Days,
Weeks, or
Months) to plot on the
X-axis for the swimmer plot for the duration of response evaluation.
