Resupply Setting page

On this page, you can set up one or more drug resupply types for the study. Resupply settings are study-specific applications of the resupply algorithm.

These supply types are linked to the sites where the resupply setting is used. Among the critical properties you set up are trigger weeks, resupply weeks, minimum and maximum buffer, initial shipment amount.

After setting up the resupply type, you should link the site to the resupply setting. This step must occur before you activate the site.

Definitions of resupply configuration settings

For more information, see the resupply configuration flowchart.

Supply Settings	How is this value set?	Definition
Trigger weeks (TW)	Supplies Resupply Setting Predictive Resupply	The minimum number of weeks of supply required to be available at the site at all times. Used to determine the Projected Need (PN). Based on the patient visit schedule. Must be less than or equal to the Resupply Weeks value. The result of projecting the quantity of drug units required to support all expected visits for active, randomized subjects between the current date and the last day of the trigger weeks.
Resupply weeks (RW)	Supplies Resupply Setting Predictive Resupply	The maximum weeks of supply at a site as a result of a resupply order. Required to determine the Total Quantity Needed (TQN). Based on the patient visit schedule. Must be greater than or equal to the Trigger Weeks value. The result of projecting the quantity of drug units required to support all expected visits for active, randomized subjects between the current date and the last day of the resupply weeks. If sufficient drug units are available for Trigger Weeks, the Resupply Weeks is not used.
Initial quantity	Supplies Resupply Setting Buffer or Predictive Resupply	The quantity of each type of drug unit that is shipped to a site when the initial trigger is reached. The initial quantity does not apply to reactivated sites. During study design, the initial shipment trigger can be when a site is activated for the first time or when the first subject is screened.
Minimum buffer (MinB)	Supplies Resupply Setting Buffer or Predictive Resupply	The minimum number of drug units needed to account for unpredictable events, such as new subjects who need to be randomized and lost or damaged supplies. Note: MinB is not a predictive value. Added to the quantity of drug units required for trigger weeks to calculate Projected Need (PN). Must be less than or equal to the Max Buffer.
Maximum buffer (MaxB)	Supplies Resupply Setting Buffer or Predictive Resupply	The maximum number of drug units needed to account for unpredictable events, such as new subjects who need to be randomized and lost or damaged supplies. Note: MaxB is not a predictive value. Required to determine the total quantity needed (TQN). Added to the quantity of drug units required for resupply weeks to calculate Total Quantity Needed (TQN). Must be greater than or equal to the Min Buffer.
Projected Need (PN)	Calculated.	Determines whether a resupply order is made. The sum of: The quantity of drug required for subject visits within the trigger weeks. The minimum buffer for each drug type. Drug units are reordered if the site available inventory quantity of drug units is less than or equal to the projected need.
Site Availability Inventory (SAI)	Calculated.	The quantity of drug units available at the site. Sum of: The total amount of drug units at this site with these statuses applied: Available, Quarantined, or Temporarily Available. The quantity of drug units in transit (included in any drug order on its way to the site). Minus: The total amount of drug that has reached the Do Not Count day (for expiry management). Note: The DNC value is applied at the lot level.
Total Quantity Needed (TQN)	Calculated.	The quantity of drug units needed to be ordered for this site. Sum of: The amount of drug required for subject visits within the Resupply Weeks. The maximum buffer for each drug type. Minus: Site availability inventory.

Field	Description	Notes

Add New Supply Type	Select this button to add a new resupply type.
Buffer Resupply	Calculates Projected Need based on the values provided on the Resupply Setting page. The Trigger Weeks (TW) and Resupply Weeks (RW) values are assumed to be zero. The form resets to show the columns appropriate to setting up trigger resupply.	Must select Buffer Resupply or Prediction Resupply.
Prediction Resupply	Calculates Total Quantity Needed (TQN) based on the values provided on the Resupply Setting page. The form resets to show the columns appropriate to setting up the prediction resupply.	Must select Buffer Resupply or Prediction Resupply.
Resupply Number	A unique identifier for the resupply strategy. This number is automatically created and incremented by IRT.
Resupply Name	A brief description of the resupply setting.	REQUIRED. Maximum: 50 characters. Alphanumeric. Special characters are permitted.
Drug Type	The drug type affected by the resupply setting.	READ-ONLY
Min Buffer	The minimum number of drug units needed to account for unpredictable events, such as new subjects who need to be randomized and lost or damaged supplies. Added to the quantity of drug units required for trigger weeks to calculate Projected Need (PN). The value for the initial shipment should be greater than the Min Buffer. Note: MinB is not a predictive value.	REQUIRED. Numeric. Range: 0 - 9999
Max Buffer	The maximum number of drug units needed to account for unpredictable events, such as new subjects who need to be randomized and lost or damaged supplies. Required to determine the total quantity needed (TQN). Added to the quantity of drug units required for resupply weeks to calculate Total Quantity Needed (TQN). This number should not be less than Min Buffer. Note: MaxB is not a predictive value.	REQUIRED. Numeric. Range: 0 - 9999
Initial	The quantity of each type of drug unit that is shipped to a site when the initial trigger is reached. The initial quantity does not apply to reactivated sites. During study design, the initial shipment trigger can be when a site is activated for the first time or when the first subject is screened A one-time order.	REQUIRED. Numeric. Range: 0 - 9999
Edit	Edit the options on the page.
Delete	Delete the resupply setting.
Prediction Resupply only
Trigger Weeks	The minimum number of weeks of supply required to be available at the site at all times. Used to determine the Projected Need (PN). Based on the patient visit schedule. Must be less than or equal to the Resupply Weeks value. The result of projecting the quantity of drug units required to support all expected visits for active, randomized subjects between the current date and the last day of the trigger weeks.	REQUIRED. Numeric. Range: 0 - 9999
Resupply Weeks	The maximum weeks of supply at a site as a result of a resupply order. Required to determine the Total Quantity Needed (TQN). Based on the patient visit schedule. Must be greater than or equal to the Trigger Weeks value. The result of projecting the quantity of drug units required to support all expected visits for active, randomized subjects between the current date and the last day of the resupply weeks. If sufficient drug units are available for Trigger Weeks, the Resupply Weeks is not used.	REQUIRED. Integer. Range: 0 - 9999
