Funding Opportunity Purpose

The purpose of this notice of funding opportunity (NOFO) is to support research studies of two or more vaccine adjuvants (combination adjuvants) in order to understand the mechanisms by which they work in concert. All adjuvants considered must have previously demonstrated immune modulating activity. The long-term goal of this research program is to improve the rational design of vaccines by predicting the immune profile elicited by combination adjuvants.

Funding Opportunity Goal(s)

To assist public and private nonprofit institutions and individuals to establish, expand and improve biomedical research and research training in infectious diseases and related areas; to conduct developmental research, to produce and test research materials. To assist public, private and commercial institutions to conduct developmental research, to produce and test research materials, to provide research services as required by the agency for programs in infectious diseases, and controlling disease caused by infectious or parasitic agents, allergic and immunologic diseases and related areas. Projects range from studies of microbial physiology and antigenic structure to collaborative trials of experimental drugs and vaccines, mechanisms of resistance to antibiotics as well as research dealing with epidemiological observations in hospitalized patients or community populations and progress in allergic and immunologic diseases. Because of this dual focus, the program encompasses both basic research and clinical research.

Section I. Notice of Funding Opportunity Description

Background

Because of their defined composition, subunit vaccines provide a variety of benefits over whole-organism vaccines. By designing a novel vaccine around a purified antigen, or set of antigens, vaccine developers can target an immune response toward specific components of a pathogen. Additionally, the molecular purity of subunit vaccines reduces safety concerns and additional regulatory hurdles. These advantages explain the increase in development of subunit vaccines over time; however, these vaccines often require the addition of exogenous immunostimulatory components, known as adjuvants, to elicit robust and long-lasting immune responses. By comparison, whole-organism vaccines contain many endogenous adjuvants that trigger numerous innate sensors in host cells. This difference in adjuvantation is thought to be a primary reason that certain whole-organism vaccines, such as the Yellow Fever and Smallpox vaccines, are superior to subunit vaccines for immunogenicity, efficacy, and durability.

Until recently, exogenous vaccine adjuvants were limited to a few types. The aluminum-based adjuvants, termed alum, were the only adjuvants used in U.S. licensed vaccines until 2009, when the U.S. Food and Drug Administration (FDA) approved Cervarix, an HPV vaccine containing the adjuvant AS04. This adjuvant, is a combination of alum and 3-O-desacyl-4'-monophosphoryl lipid A (MPL-A), an immune-stimulating lipid that activates Toll Like Receptor 4 (TLR4) on innate immune cells. In the years since, the FDA has approved 5 more vaccines containing non-alum adjuvants, demonstrating the real-world practicality of exogenous adjuvants in subunit vaccines. The adjuvants used in these vaccines include cytosine phosphoguanine (CpG; a TLR9 agonist), MF59 (an oil in water emulsion), and AS01 (a combination of MPL-A and the saponin QS-21).

While these recent approvals bring the number of licensed non-alum adjuvanted vaccines in the United States to six (with four containing combination adjuvants), new adjuvants are needed to improve vaccine efficacy in neonates, young children, pregnant women, the immune compromised, and older adults. In addition, the currently used adjuvants may not induce the types of immune responses required to protect against infectious agents for which vaccines currently do not exist. Recent technologic and scientific advances are increasing our understanding of the pathways regulating innate and adaptive immune responses, offering opportunities to develop novel or modify existing adjuvants to safely trigger long-term protective immunity.

The development of effective adjuvants is a high-priority research area for the National Institute of Allergy and Infectious Diseases (NIAID). In April 2018, NIAID convened a Blue-Ribbon panel to review and further refine the Institute’s research agenda for the discovery, development, and clinical evaluation of vaccine adjuvants. With the panel’s input, NIAID developed the Strategic Plan for Research on Vaccine Adjuvants, which included recommendations to support adjuvant research beyond the use of individual adjuvants (i.e., using combination adjuvants). In addition, recent findings of vaccine potentiation by combination adjuvants support the need for mechanistic research in this area. Although some combinations, such as AS01 (liposome-based combination adjuvant containing MPL and the saponin QS-21) and AS04 (alum + MPL-A), are used in licensed vaccines, the molecular underpinnings of their adjuvant effects are not fully understood.

The use of combination adjuvants within vaccine formulations offers the potential to fine-tune the resulting immune response toward a desired phenotype for a targeted disease or population. Furthermore, combination adjuvants can be used to broaden an immune response and overcome immunodominance of individual pathogen epitopes – potentially providing protection against multiple pathogens in one or a few vaccine(s) and decreasing the number of vaccines necessary for maintaining public health. However, it has proven to be exceedingly difficult to predict how adjuvants will work in combination with one another, even if the individual immune profiles are known for each adjuvant. Pairs of adjuvants can lead to effects that are synergistic, additive, or antagonistic and it is difficult to predict these outcomes prior to directly testing their immunogenicity in combination with one another. Improved understanding of the mechanisms of combination adjuvants is needed to move closer to the ultimate goal of combination adjuvants informing rational design of optimized vaccine formulations.

NIAID initiated the Molecular Mechanisms of Combination Adjuvants (MMCA) program in 2016 to promote the investigation of new adjuvant combinations and to understand the mechanisms by which combination adjuvants improve vaccines. The program was renewed in 2021 and seven awards were made to study a variety of different adjuvant combinations. Previous participants in the MMCA program have performed systematic analyses of various combination adjuvants, identified combinations that targeted multiple innate immune pathways or enhanced B and T cell mediated immunity, examined fundamental mechanisms associated with differences in responses to infections versus adjuvanted vaccines, and characterized induction of tissue-specific immunity.

Research Objectives

This program supports research to define the molecular and immunological mechanisms triggered by adjuvant combinations leading to long-term protective immunity against infectious diseases. Studies must explore the mechanism(s) of action (MOA) of combination adjuvants that have already been shown individually to be effective in enhancing or modulating immune responses when compared with antigen alone (i.e., model antigens, pathogen-derived molecules, or vaccine components). At least one adjuvant combination must be proposed for examination, but additional combinations also are allowed. Applicants should include a strong rationale for combining adjuvants based on what is known about their individual immunostimulatory properties and/or effects in previously studied vaccines. Adjuvant combinations that include non-Toll-like receptor (TLR) agonists are of particular interest.

Other requirements of the program include: 1) examination of immune mechanisms in animal models; and 2) if standard inbred and germ-free mouse models are used, validation in more complex model systems (e.g., Collaborative Cross mice, microbial experienced (“dirty”) mice, humanized mice, other relevant animal models, in vitro human models, etc.) to demonstrate translatability toward human use. The mechanisms explored may include, but are not limited to, stimulation of multiple immune receptors, or activation of multiple signaling pathways in animal models or in in vitro systems. Use of in vitro systems is allowed and inclusion of human samples (primary cells, tissue samples, and/or cell lines) is encouraged.

MOA studies may include, but are not limited to:

  • Quantitative and qualitative assessments of antibody production, avidity, and function
  • CD4 and CD8 T cell activation and function
  • Induction and maintenance of innate and adaptive immune memory
  • Tissue-specific immunity
  • Studies of signaling pathways and cascades
  • Characterization of innate immunity including, but not limited to, studies of dendritic cells, macrophages, NK cells, innate lymphoid cells, neutrophils, and complement
  • Pathogen challenge studies showing protective efficacy or mitigation of disease
  • Systems immunology analyses
  • Safety studies, such as measurement of serum levels of proinflammatory cytokines or determination of weight loss, fever, or tissue damage to demonstrate improved immunogenicity without increased reactogenicity
  • Determination of correlates of immunity
  • Use of computational/mathematical modeling to examine MOA and synergistic effects (must include experimental validation)

Applications including the following types of studies will be considered non-responsive and will not be reviewed:

  • Studies on AIDS, HIV, or SIV
  • Projects that do not examine immune mechanisms in animal models
  • Projects that only examine immune mechanisms in standard inbred and germ-free mouse lines without validation and/or further mechanistic examination using more complex model systems (e.g., Collaborative Cross mice, microbial experienced (“dirty”) mice, humanized mice, other relevant animal models, in vitro human models, etc.)
  • Projects that use only one adjuvant without combining it with at least one additional adjuvant
  • Clinical trials (all phases). However, the use of samples obtained from human subjects in clinical trials funded through other mechanisms is allowed, as is the use of samples obtained from human subjects treated with licensed vaccines or drugs for the FDA-approved indication.
  • Projects focused primarily on screening assays to identify adjuvants or adjuvant combinations, rather than on mechanism of action.
  • Projects that focus primarily on technology, reagent, or animal model development. However, these may be included as necessary parts of the project if well justified by the research aims and preliminary data.
  • The use of compounds that have not previously been shown to have adjuvant activity when used individually or when used in combination.
  • Studies that are focused on the development of vaccines or on determining vaccine efficacy, rather than focusing on the mechanisms of action of combination adjuvants.

Intra-Program Collaboration

In order to promote collaboration among program participants, each applicant will set aside a minimum of $50,000 in direct costs during each year of research, beginning in Year 2. These funds will be used for collaborative projects amongst the MMCA investigators that will be identified and planned during the first year of award of the project period and reassessed during subsequent years of the program. Investigators should not include or propose specific collaborative projects within their application.

Annual Meeting and Site Visits

A kickoff meeting and subsequent annual meetings will be organized by NIAID in order for grant recipients to present both positive and negative results, identify new collaborations, and share materials, including reagents and techniques among all awarded investigators. These meetings will convene yearly in the Rockville, Maryland area. The Principal Investigator(s)/Program Director(s) (PD[s]/PI[s]) from each award is/are required to attend the kickoff meeting and annual meetings.

Annual site visits from NIAID program staff will be conducted at the request of the NIAID Program Officer and take place at the recipient institution. The PD(s)/PI(s) will plan the meeting time and agenda in coordination with NIAID program staff and arrange for key project personnel to be available to give presentations and interact with NIAID staff at the meeting.
