SUPPLEMENTARY INFORMATION: The NTP Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) announces an ‘‘International Workshop on Alternatives to the Murine Histamine Sensitization Test (HIST) for Acellular Pertussis Vaccines: State of the Science and the Path Forward.’’ This workshop, the third in a series of specialized vaccine workshops, will review new methods and approaches for acellular pertussis (aP) vaccine safety testing that incorporate innovations in science and technology. These scientific innovations should improve test accuracy, precision, and efficiency while also reducing or replacing the use of animals in vaccine safety testing. The goal is to address the path toward global validation, acceptance, and implementation of scientifically valid alternative methods for aP vaccines. The workshop is open to the public at no charge with attendance limited only by the available space; however, advance registration is required (see Background Pertussis, also known as whooping cough, is a highly contagious disease caused by the bacterium Bordetella pertussis. Pertussis was one of the most common childhood diseases of the early 20th century and was once a major cause of childhood mortality in the United States. A whole-cell vaccine introduced in the 1940s reduced the incidence of pertussis by more than 80%. aP vaccines, which became available in the 1980s, were developed in response to public concern with some common side effects (e.g., fever, swelling at injection site) and rare serious events that coincided with the use of whole-cell pertussis vaccines. These new generation aP vaccines contain different combinations of the putative protective antigens of B. pertussis bacteria (e.g., inactivated pertussis toxin [PTx/d], pertactin, and fimbriae) and are less reactogenic than whole-cell vaccines. Regulatory authorities require safety, potency, and purity testing prior to the release of each production lot of pertussis or pertussis antigen-containing vaccines.

This test is performed to ensure that PTx has been effectively inactivated before release of vaccines (Corbel and Xing, 2004). However, such testing may involve large numbers of mice, some of which can experience significant unrelieved pain and distress. In addition, the HIST has technical challenges requiring frequent retesting, thereby increasing vaccine testing expense and animal usage. An international workshop organized in 2010 1 by NICEATM, Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM), and their international partners identified the HIST as a priority for future research, development, and validation of alternative test methods that could further reduce, refine (enhance animal well-being and lessen or avoid pain and distress), or replace animal use for aP vaccine safety testing (Stokes et al., 2011). Two international workshops reviewed currently available alternative in vitro assays to the HIST and discussed a path forward to achieve their validation and adoption 2 3. The Workshop on Animal-Free Detection of PTx in Vaccines—Alternatives to HIST was held on June 9 and 10, 2011, at the Paul Ehrlich Institute, Germany. An International Working Group for Alternatives to HIST (previously designated as the ‘‘Spiked-vaccine Working Group’’) was organized to coordinate future studies on relevant alternative methods (Bache et al., 2012; Isbrucker, 2011). The Alternative Safety Testing Strategies for Acellular Vaccines Workshop was held on August 21, 2011, as a satellite meeting to the 8th World Congress on Alternatives and Animal Use in the Life Sciences in Montreal, Canada (Isbrucker, 2011). Participants at this workshop further discussed and clarified regulatory agency requirements to achieve the acceptance of alternative methods to the HIST and agreed that conducting a study using spiked vaccines to compare the sensitivities of the HIST and in vitro assays would be important. 1 International Workshop on Alternative Methods to Reduce, Refine, and Replace the Use of Animals in Vaccine Potency and Safety Testing: State of the Science and Future Directions, Bethesda, MD, USA September 14–16, 2010. 2 Workshop on Animal-Free Detection of PTx in Vaccines—Alternatives to HIST, Langen, Germany, June 9–10, 2011. 3 Alternative Safety Testing Strategies for Acellular Pertussis Vaccines (8th World Congress Satellite meeting), Montreal, Canada, August 21, 2011.

SUPPLEMENTARY INFORMATION:

Background

    Pertussis, also known as whooping cough, is a highly contagious 
disease caused by the bacterium Bordetella pertussis. Pertussis was one 
of the most common childhood diseases of the early 20th century and was 
once a major cause of childhood mortality in the United States. A 
whole-cell vaccine introduced in the 1940s reduced the incidence of 
pertussis by more than 80%. aP vaccines, which became available in the 
1980s, were developed in response to public concern with some common 
side effects (e.g., fever, swelling at injection site) and rare serious 
events that coincided with the use of whole-cell pertussis vaccines. 
These new generation aP vaccines contain different combinations of the 
putative protective antigens of B. pertussis bacteria (e.g., 
inactivated pertussis toxin [PTx/d], pertactin, and fimbriae) and are 
less reactogenic than whole-cell vaccines.
    Regulatory authorities require safety, potency, and purity testing 
prior to the release of each production lot of pertussis or pertussis 
antigen-containing vaccines. The murine histamine sensitization test 
(HIST) is a key safety test used to monitor residual levels of 
pertussis toxin (PTx) in vaccines. This test is performed to ensure 
that PTx has been effectively inactivated before release of vaccines 
(Corbel and Xing, 2004). However, such testing may involve large 
numbers of mice, some of which can experience significant unrelieved 
pain and distress. In addition, the HIST has technical challenges 
requiring frequent retesting, thereby increasing vaccine testing 
expense and animal usage. An international workshop organized in 2010 
\1\ by NICEATM, Interagency Coordinating Committee on the Validation of 
Alternative Methods (ICCVAM), and their international partners 
identified the HIST as a priority for future research, development, and 
validation of alternative test methods that could further reduce, 
refine (enhance animal well-being and lessen or avoid pain and 
distress), or replace animal use for aP vaccine safety testing (Stokes 
et al., 2011).

---------------------------------------------------------------------------

    Two international workshops reviewed currently available 
alternative in vitro assays to the HIST and discussed a path forward to 
achieve their validation and adoption 2 3. The Workshop on 
Animal-Free Detection of PTx in Vaccines--Alternatives to HIST was held 
on June 9 and 10, 2011, at the Paul Ehrlich Institute, Germany. An 
International Working Group for Alternatives to HIST (previously 
designated as the ``Spiked-vaccine Working Group'') was organized to 
coordinate future studies on relevant alternative methods (Bache et 
al., 2012; Isbrucker, 2011).

---------------------------------------------------------------------------

    The Alternative Safety Testing Strategies for Acellular Vaccines 
Workshop was held on August 21, 2011, as a satellite meeting to the 8th 
World Congress on Alternatives and Animal Use in the Life Sciences in 
Montreal, Canada (Isbrucker, 2011). Participants at this workshop 
further discussed and clarified regulatory agency requirements to 
achieve the acceptance of alternative methods to the HIST and agreed 
that conducting a study using spiked vaccines to compare the 
sensitivities of the HIST and in vitro assays would be important.

[[Page 52334]]

    Several in vitro assays have been developed, or are currently under 
development, with the aim of finding an alternative method to the HIST 
for monitoring residual PTx activity in aP vaccines. The International 
Working Group for Alternatives to HIST is coordinating the acquisition 
and distribution of aP vaccine samples from manufacturers to research 
laboratories for generation of data using in vitro methods to evaluate 
vaccines spiked with a known amount of PTx. Data from the various 
alternative assays will be presented at the upcoming workshop and will 
form the basis for identifying in vitro methods for future assessment 
in the next international collaborative study.
    The following methods will be evaluated and may be used to generate 
data to be presented at the upcoming workshop:

1. Binding assay: used to assess the amount of PTx/toxoid binding 
activity to the glycoprotein fetuin
2. Enzymatic assay: monitors the residual ADP-ribosylation of the PTx/
toxoid
3. Cell-based assays: monitor the generation of cAMP or decrease in 
cellular ATP following exposure to PTx
4. Genetic assays: determine potential genomic markers of PTx activity

    This workshop will provide a forum to discuss and review the in 
vitro protocols and available data from the International Working Group 
for Alternatives to HIST study and will suggest future collaborative 
projects using prepared materials. The workshop will also review 
additional new methods and approaches for aP vaccine safety testing 
that should improve test accuracy, precision, and efficiency while also 
reducing or replacing the use of animals in vaccine safety testing. 
Finally, the workshop will address the path toward global validation, 
acceptance, and implementation of scientifically valid alternative 
methods for aP vaccines.
