PKS study data

If study files are saved to the study library, no mapping is necessary. However, if a study is going to be saved to the PKS from Phoenix, the data source and its columns must to be mapped before creating the study in the PKS. Only one data source needs to be selected. The data source can be imported from a disk or selected from an open project.

Once a data source is selected the observation data, demographic data, and other data must be mapped to the appropriate columns. A .map file can be created and saved or properties can be loaded from a previously created .map file.

Note:If a sample, dose, or demographic source field contains multiple values, use one of the following options to prevent leading zeros or commas from being stripped:
– include a space between the values (e.g., “01, 2, 3”)
– include quotes in the value, so in a CSV file, it would be “”01,2,3””
– include any non-numeric characters in the value

Selecting a data source

There are two ways to add a data source: selecting a file from a disk or selecting a worksheet in a Phoenix project.

Click Browse Files.

In the Open dialog, select a worksheet or workbook then click Open.

In the Options area of the File Import Wizard, specify any additional import options.

Click Finish to add the worksheet or workbook.

Click Browse Projects.

In the Select Source dialog, click the (+) signs beside workbooks and operational object results to locate a data source.

Use the pointer to select the data source.

Click Select.

The Select Object dialog closes and the selected data source is listed in the Data Source field.

Mapping study data

Study data can be mapped to PKS structures and saved as a .map file, loaded from an existing map file on a disk, or loaded from an existing .map file in the PKS.

Use the Remove button to unmap a selected column.

Enter an alternative name for the selected column by typing it in the Target Name field.

Select the mapped column in the list to display attributes that can be modified.

If the attribute values are in a separate column, click and drag that column to the attribute field.
(For example, if units are recorded as a separate column in the data source, click and drag that column name from the Source Column list to the Units attribute text field.)

If the attribute value is always the same (i.e., static), enter that value and select the Static checkbox.

The Demographics tab maps subject data such as demographics and covariates.The selected demo­graphic columns must contain values that exist once per subject. That is, the values are not time or visit dependent.

The Samples tab is for mapping time-dependent sample results and contains the following column attributes.

Unit: Units of measurement.

Status: Indicates data status, for example, below a limit of quantification (BQL), or missing due to dropout or non-adherence. Valid data are finite. The list of statuses is defined by a PKS adminis­trator.

Sample_Number: Sample identifier.

Sample_Matrix: Identifier for the sample matrix.

Sample_Description: Further information about the sample.

Analytical Method: Assay or technique used to obtain the sample data.

LLOQ: Lower limit of quantification for the assay. A numerical value.

ULOQ: Upper limit of quantification for the assay. A numerical value.

The Doses tabs contain the following column attributes.

Unit: Units of measurement.

Status: Indicate data status, for example, below a limit of quantification (BQL), or missing due to dropout or non-adherence. Valid data are finite. The list of statuses is defined by a PKS adminis­trator.

Sample_Number: Sample identifier.

Sample Description: Text information about the sample.

Route: Variable identifying route, oral, IV, IM, etc., for each dose.

The Data Collection Point tab (and Default Data Collection Point tab) is used to specify columns that contain data used to uniquely identify events where samples were collected or doses were adminis­tered. The mappings can be overridden per dose or sample. The following column attributes are avail­able on the Data Collection Point tab:

Period: Identifier for the period of the study.

Phase: Identifier for phase of the study.

Matrix: Matrix value, if study involves a matrix of analyte and concentration combinations.

Day: Number of days after the study, phase, period started.

Visit: Identifier for the visit during which observation was made/sample was taken.

Analyte: ID of the analyte used.

DCP Description: (Data Collection Point description) use this field for variables that distinguish different measurements stored a single observation column, for example, an indicator variable noting whether a given record contains a measurement of plasma concentration or pain score.

Relative_Nominal_Time: Scheduled time of observation or sampling since last dose.

Nominal_Time_Unit: Sample identifier.

Relative_Nominal_End_Time: Identifier for the sample matrix.

Relative_Actual_Time: Further information about the sample.

Relative_Actual_End_Time: Assay or technique used to obtain the sample data.

Actual_Clock_Time: Lower limit of quantification for the assay. A numerical value.

The Treatment tab (and Default Treatment tab) is used to specify columns that uniquely identify administered treatments. Treatment information is combined with data collection point information to uniquely identify events where samples were collected or doses were administered. The following column attributes are available on the Treatment tab:

Treatment: Variable identifying the treatment.

Treatment_Description: Additional descriptive field.

Route: Variable identifying route, oral, IV, IM, etc., for each dose.

Regimen: Variable identifying dose regimen.

Fasted_Fed: Variable identifying whether subject ate before dosing.

Formulation: Variable identifying drug formulation for each dose.

State: Additional descriptive field.

The Default Treatment mappings can be overridden per dose or sample.

The map file is used to create the study.

Loading a study map from a file

The loaded mappings are applied and attached to the study.

The mappings are applied to the selected data source as closely as possible. Phoenix displays warn­ing messages if there are any problems with the mappings.
