information in order to avoid revealing the participant’s
blinded treatment assignment.
Active and placebo investigational drug products must
be identical in appearance, labeling, preparation time, expi-
ration date and time, and supplies used. Considerations when
preparing blinded investigational drug products include
•
Ensuring that the preparation times for the active drug
and the placebo dose are the same.
•
Providing the identical information on the active drug
and placebo labels, including the expiration date and
time; if the active drug and placebo products have dif-
ferent expiration dates and times, the shorter of the 2
times should be used.
•
Making the port on intravenous bags look the same
(i.e., if a commercial bag of diluent is used as the
placebo, insert a needle into the port using aseptic
technique to give the appearance that a drug has been
added; if additive port covers are used, ensure match-
ing covers).
•
Using the same type of needle and tubing for adminis-
tration of the active drug and the placebo dose.
An unblinding process must be established that allows the
blinded treatment assignment to be determined. Examples of
events that require unblinding include a research participant
experiencing a severe adverse reaction and an unauthorized
person ingesting or being administered the investigational
drug product. An unblinding process that allows for immedi-
ate determination of the participant’s treatment assignment
or access to the sponsor’s medical monitor should be devel-
oped. In order to allow continuous access to the unblinding
process in the event of an emergent need to determine a par-
ticipant’s treatment assignment, a clinical site-specific plan
should be developed that is not dependent solely on the PI.
When labeling a blinded study medication, the clinical
research pharmacy must label it such that the blinding is pro-
tected and that clinical site study staff are not able to deter-
mine the actual contents of the container. The product should
be labeled as “drug name or placebo.” The protocol acronym
should not be used solely in place of the product name; if a
research participant presents at an emergency department,
the treating physician should be able to identify the potential
contents of the container so that treatment is not delayed.
Barcoding of Investigational
Drug Products
Improved patient safety with barcoding has been well docu-
mented.
17
Although barcoding is desirable, the lack of a
standard system limits its ability to be implemented with
investigational drug products. Development of a standard-
ized barcode lexicon that will facilitate the implementation
of a global barcoding system is necessary. ASHP has urged
the Food and Drug Administration (FDA) and other regula-
tory agencies, standard-setting bodies, contracting entities,
health systems, and pharmaceutical manufacturers to de-
velop and implement a universal symbology (e.g., barcodes,
radio frequency identifiers) that are readily deciphered by
commonly used scanning equipment to code for the National
Drug Code, lot number, and expiration date on all unit dose,
unit-of-use, and injectable drug packaging.

Investigational Drug Product
Accountability and Documentation
Detailed records, required to be kept by the sponsor, must
identify the investigator to whom the investigational drug
product is shipped as well as the date, quantity, and batch or
code mark of such shipment.
19
The clinical site is required to
maintain records detailing the participant to whom the inves-
tigational drug product was dispensed, the date, the quantity,
and the batch or code mark dispensed. Incomplete or inac-
curate drug accountability is a deficiency frequently cited in
Form FDA 483 Inspectional Observations notices.
20
U.S. law
does not require the use of an expiration date, use-by date,
or retest date on product labels. In many cases, the date may
be found on the packing slip; however, the clinical research
pharmacy may reach out to the sponsor to request documen-
tation of the retest or expiration date.
Routine inventory counts (e.g., monthly) should be
performed for each investigational drug product in order to
ensure that the physical quantity on hand corresponds to the
quantities recorded on the drug accountability record form
(DARF) and to manage investigational drug product with
limited use dates. Any discrepancy should be reviewed and
resolved for each investigational drug product.
According to the CFR and GCP guidelines,
1,2
inves-
tigational drug product receipt, dispensing, participant re-
turns, and disposition are required transactions that must
be documented. Sponsors may provide investigational
drug product accountability records, or individual clinical
research pharmacies may have their own accountability re-
cords. Frequently, sponsor-provided DARFs do not contain
sections to document all of the required transactions. For
clinical research pharmacies with multiple ongoing clinical
studies, DARFs from different sponsors requiring inconsis-
tent information can cause confusion. Use of standardized
DARFs containing sections for the required transactions
would ensure consistency and compliance with applicable
regulations. Figure 1 displays a template for a DARF, which
can be customized for different clinical protocols and sites
but maintains a standard appearance that will allow clini-
cal research pharmacy personnel to complete the forms cor-
rectly and provide sponsors with the required documenta-
tion. The form allows the site to document the receipt and
dispensing of individual bottles, vials, or kits, and the header
of the form can be customized for the specific needs of the
protocol. If a hard copy of the DARF is required by sponsors
and an electronic dispensing/accountability system is used,
it must have the capability of printing a hard copy of the
DARF that shows the required transactions. At a minimum,
the items on the form should be adhered to, ensuring site and
sponsor compliance with regulatory agencies. The clinical
research pharmacy DARF may be customized to include ad-
ditional information requested by sponsors, such as the time
of dose preparation or investigational drug product container
numbers.
When the investigational drug product is transferred
from the clinical research pharmacy to a satellite pharmacy
or dispensing location, a separate DARF must be main-
tained with the investigational drug product. The DARF in
the clinical research pharmacy should reflect the transfer of
investigational drug product to the satellite location, and the
satellite location’s DARF should reflect receipt of the inves-
tigational drug product from the clinical research pharmacy.
