Section I. Notice of Funding Opportunity Description

Purpose

Through this Notice of Funding Opportunity (NOFO), the National Cancer Institute (NCI) encourages grant applications to study novel microbial-based cancer therapy (including therapies for oral cancer), imaging detection, and diagnosis strategies to overcome the limitations of inadequate conventional cancer imaging and therapies. Solutions may utilize bacteria, archaebacteria, bacteriophages, and other microorganisms and their products (but not oncolytic viruses).

This NOFO utilizes the R21 award mechanism for exploratory/developmental projects. The R21 mechanism is suitable for projects that are at their inception, conceptual, or idea-based phase where proof-of-principle of the proposed methodology has not been established with the aim to demonstrate core functional capabilities of the proposed approach. In this phase, the technical feasibility of the proposed technology or methodology should not yet have been established.

This NOFO runs in parallel with a companion NOFO, PAR-25-107 , which uses the Research Project (Grant R01) mechanism. It is the appropriate NOFO for more mature applications that include preliminary data that demonstrate the feasibility of the specific aims.

Background and Rationale

Background and rationale Early clinical observations in the 1880s by Coley pioneered the concept of using bacteria (or their products) as microbial-based cancer therapy and demonstrated that tumor regression coincided with natural bacterial infections, leading to the first use of microbes as antitumor agents. With the development of the more effective and better-understood radiation therapy, and later, chemotherapy-based cancer therapies, this approach was largely abandoned in the 1930s and microbial-based therapy has remained an elusive goal. However, standard cancer therapies have several major disadvantages, including the rarity of complete and sustained remissions of most solid tumors, the development of resistance, frequent failure to clear micrometastases, and relapse. To overcome the limitations of current cancer imaging and therapies, microbial tumor homing and colonization, oncolysis, and activation of anti-tumor immunity are being explored as alternative strategies. Because Bugs as Drugs are potentially self-regenerated cancer therapeutics, the approach may address cancer therapy needs for global health and low resource settings

Mechanisms of microbial-based Cancer Therapy

Several facultative or obligate anaerobic bacteria possess unique natural or genetically engineered potential to overcome traditional therapeutic limitations by selectively targeting tumors and/or anti-tumor immunity. For example, Salmonella, Escherichia coli, Clostridium, Bifidobacterium, or Listeria are naturally capable of selective homing to tumors when systemically administered, resulting in high levels of colonization and replication in locally hypoxic tumor microenvironments or within tumor tissues leading to killing tumor cells, reprograming the immune system to target cancer cells. Therapeutic bacteria can stimulate the production or localized in the tumor of CD8+T lymphocytes or block immune checkpoint pathways.

Microbial products (including microbial toxins) and microbial metabolites are also associated with anti-tumor activities. Microbial metabolites can inhibit tumor cells growth in vitro, modulate T-cell response to checkpoint inhibitors, reduce carcinogenic inflammation, inhibit tumor cell invasion and migration, suppress histone deacetylase activity, and induce apoptosis

Cancer Clinical Needs and Challenges

There is a need for improved cancer therapies (including therapies for oral cancer), especially for solid tumors where conventional therapies often fail under conditions such as poorly vascularized tumors with inadequate blood perfusion, hypoxia, nutritional deprivation, tumor interstitial pressure, immature lymphatic system, immunosuppressive microenvironment, tumor dormancy, distant tumor metastasis, slowly dividing cells resistant to treatment, or islands of microinvasive tumor cells buried within normal tissues and drug resistance. In addition, it is important to develop new cancer immunotherapy modalities. Among the most attractive characteristics of microbial agents for anticancer therapies is their capacity for tumor-specific targeting and activation of the immune system. Thus, for example, it may be possible to develop a bacteria-based cancer treatment platform for in situ release of immune checkpoint inhibitors.

Recent research advancements in bacterial anti-cancer activities

Multiple studies have demonstrated that anaerobic microorganisms have the unique ability to grow selectively in hypoxic immunosuppressed areas of solid tumors that often are not accessible to drugs. More recently, an integrated bacterial cancer treatment approach utilizing a single multi-function, bacterial payloads for cancer imaging, activation of the immune system, and tumor cell killing were demonstrated. A white paper on the Challenges and Opportunities of Microbial Anti-Cancer Therapy and Prevention summarizes the potential of microbial therapy and recent research advances. Promising results from these studies and the availability of sophisticated gene-editing technology, offer the prospect of developing new concepts and strategies for the use of microbial therapies to mitigate or solve unmet clinical needs. Other studies have shown that gut microbial metabolites can modify the transcription, epigenetics, and metabolism of host immune cells, which can be utilized to activate the immune system. While recent research demonstrates the potential of microbial-based cancer therapy, more research is needed to realize this potential and to bring novel microbial-based therapies to the clinic especially for conditions where conventional cancer therapies are inadequate

Scope and Research Objectives of this NOFO

The complex nature of the interactions between the microbe, tumor, and immune system requires multidisciplinary collaboration between microbiologists, cancer researchers, and immunologists with the goal of developing innovative approaches to improve our understanding of this system and utilize it for cancer therapy. This initiative seeks to support studies of tumor-microbe interactions needed to develop new cancer imaging and therapy strategies that address unmet clinical needs. The multi-disciplinary research teams are expected to conduct cutting-edge research aimed at advancing pre-clinical development of novel bacteria-based anticancer therapeutic or diagnostic agents. The goal is to conduct research that could have a major impact on cancer therapy and related research

Multi-disciplinary research teams are expected to conduct cutting-edge research within the scope of the NOFO (see above) aimed at advancing pre-clinical development of novel microbial-based anticancer therapeutic agents, cancer imaging, and diagnostics technologies, or to study the complex biology involved in the interplay of microbe-tumor-immune system interactions. Applicants applying to this NOFO are expected to address both the microbial and the tumor aspects of microbial cancer therapy, the goal is to conduct research that could have a major impact on cancer therapy and related research.

Potential areas of research may include, but are not limited to:

  • The basic biology of the underlying microbe-tumor interactions such as invasion, lysis, antigen presentation, and other microbe-initiated tumor cell death;
  • Microbial (or microbial products) interactions with the immune system, including microbial induction of specific antitumor immunity for primary and metastatic tumors, including immune engagement, more robust tumor antigen presentation, immunostimulatory constructs such as “trojan horse” delivery of novel antigen expressions to overcome immune suppression;
  • Tumor cell inactivation (including colonization, disrupting cell function, activation of cell death programs, etc.);
  • Novel microbial species that might have therapeutic/imaging potential e.g., soil, aquatic and plant, bacteria, archaebacteria, bacteriophages, and other non-oncolytic viruses as potential therapeutics to overcome the issues of microbial pathogenicity and clearance by the immune system;
  • The dynamics of microbe-tumor interactions and biological factors limiting the effectiveness of microbial-based cancer therapy;
  • The Molecular mechanisms by which microbes and microbial products modulate cancer treatment responsiveness;
  • Interaction between microbes or microbial products with the immune system to develop novel cancer immunotherapies;
  • Novel microbial cancer-targeting approaches;
  • Novel microbial anti-cancer products (including microbial toxins) and microbial metabolites;
  • Integrated multi-function bacterial payload for cancer imaging and therapy;
  • Microbial bioreactors for self-supplied tumor localized antitumor agents;
  • Microbial based imaging for cancer detection and diagnosis
  • Approaches for treating poorly vascularized hypoxic solid tumors or islands of microinvasive tumor cells buried within normal tissue;
  • Approaches for treating distant tumor metastasis;
  • Activation of anti-tumor immunity (including expressing foreign proteins on the surface of the tumor cell);
  • Microbial based asymptomatic cancer detection;
  • Activation of dormant tumor cells;
  • Natural or engineered non-pathogenic microbes with therapeutic potential to selectively infect and treat cancers of various organs, solid tumors, metastasis, microinvasion, hypoxic or poorly vascularized tissues not accessible to chemical or monoclonal antibody drugs;
  • Targeting specificity for primary and metastatic tumors, hypoxic tissues, poorly vascularized tissues, neovascularization, or slowly dividing/dormant cancer cells;
  • Novel microbial drug delivery approaches and microbial payload delivery of anti-cancer drugs, imaging agents, radiotherapy, other tumor-relevant payloads;
  • Long-lasting approaches to anti-cancer immunity, such as the surface expression of foreign proteins to induce a strong response or overcome immune suppression;
  • Tumor cell inactivation, such as colonization, cell function disruption, programmed cell death activation;
  • Approaches to balance among microbe-initiated immune stimulation, cancer neoantigen presentation, therapeutic microbes' clearance, and microbial pathogenicity for more nearly optimal safety and efficacy of microbial-based anti-cancer agents; and
  • Strategies to prevent a recurrence, such as prolonging microbial therapy efficacy with libraries of “foreign” antigens to restimulate the immune system after loss of initial antigen efficacy.

Microbial-based Cancer Detection and Diagnosis

Microbial species with cancer-selective homing to tumors and colonization have the potential to overcome traditional cancer detection and diagnosis limitations, especially for asymptomatic cancers. Microbes are potentially useful for tumor detection and diagnosis and may provide information about the tumor organ site and characteristics, which facilitates cancer staging, management, and treatment

Microbial-based Cancer Detection and Diagnosis Specific Research Areas:

  • Enhancing bacterial tumor colonization for cancer detection and diagnosis applications;
  • Analysis of microbial-cancer specific organ targeting for cancer detection and diagnosis;
  • Microbial-based cancer diagnosis/detection technologies (including blood microbial “biomarkers”, DNA, metabolite, or other microbial characteristics;
  • Manipulation of the microbial tumor population to improve cancer therapy;
  • Microbial labeling for microbial-based cancer imaging detection;
  • Microbial-based cancer distant tumor metastasis detection; and
  • Microbial-based detection of asymptomatic cancers.

Microbial-based Cancer Imaging

Many facultative or obligate anaerobic bacteria and engineered bacteria are capable of selective homing and penetrating tumors when systemically administered which is potentially useful for tumor in vivo imaging. By using tumor-specific colonization properties of labeled bacteria, it may be possible to enhance the resolution and sensitivity of various in vivo tumor imaging modalities including CT, MRI, PET, SPECT, ultrasound, optical imaging, etc. for tumor margin detection/excision.

Cancer Imaging Specific Research Areas:

  • Enhancing bacterial tumor colonization and penetration for imaging applications;
  • Microbial-specific contrast agents and molecular imaging probes for the various in vivo imaging modalities;
  • Microbial labeling for microbial-based cancer detection;
  • Developing precise spatiotemporal resolution (including computation and image manipulation) of microbial-based cancer imaging;
  • Microbial-based image-guided tumor margin detection/accurate excision;
  • Microbial-based cancer distant tumor metastasis imaging; and
  • The microbial-based image-guided drug, gene, or radiation therapy in vivo.

Reviewers will evaluate Factors 1, 2 and 3 in the determination of scientific merit, and in providing an overall impact score. In addition, Factors 1 and 2 will each receive a separate criterion score. 

 

Significance

  • Evaluate the importance of the proposed research in the context of current scientific challenges and opportunities, either for advancing knowledge within the field, or more broadly. Assess whether the application addresses an important gap in knowledge in the field, would solve a critical problem, or create a valuable conceptual or technical advance.
  • Evaluate the rationale for undertaking the study, the rigor of the scientific background for the work (e.g., prior literature and/or preliminary data) and whether the scientific background justifies the proposed study.

Innovation

  • Evaluate the extent to which innovation influences the importance of undertaking the proposed research. Note that while technical or conceptual innovation can influence the importance of the proposed research, a project that is not applying novel concepts or approaches may be of critical importance for the field.
  • Evaluate whether the proposed work applies novel concepts, methods or technologies or uses existing concepts, methods, technologies in novel ways, to enhance the overall impact of the project.

Specific to this NOFO: Evaluate whether the application addresses inadequaciesin conventional cancer imaging or therapies, such as metastatic tumors, poorly vascularized, hypoxic, solid tumors, dormant or slowly dividing cells resistant to current interventions, and islands of microinvasive tumor cells buried within normal tissues and brain tumors.

 

Approach

  • Evaluate the scientific quality of the proposed work. Evaluate the likelihood that compelling, reproducible findings will result (rigor) and assess whether the proposed studies can be done well and within the timeframes proposed (feasibility).

Rigor:

  • Evaluate the potential to produce unbiased, reproducible, robust data.
  • Evaluate the rigor of experimental design and whether appropriate controls are in place.
  • Evaluate whether the sample size is sufficient and well-justified.
  • Assess the quality of the plans for analysis, interpretation, and reporting of results.
  • Evaluate whether the investigators presented adequate plans to address relevant biological variables, such as sex or age, in the design, analysis, and reporting.
  • For applications involving human subjects or vertebrate animals, also evaluate:
    • the rigor of the intervention or study manipulation (if applicable to the study design).
    • whether outcome variables are justified.
    • whether the results will be generalizable or, in the case of a rare disease/special group, relevant to the particular subgroup.
    • whether the sample is appropriate and sufficiently diverse to address the proposed question(s).
  • For applications involving human subjects, including clinical trials, assess the adequacy of inclusion plans as appropriate for the scientific goals of the research. Considerations of appropriateness may include disease/condition/behavior incidence, prevalence, or population burden, population representation, and/or current state of the science.

Feasibility:

  • Evaluate whether the proposed approach is sound and achievable, including plans to address problems or new challenges that emerge in the work. For proposed studies in which feasibility may be less certain, evaluate whether the uncertainty is balanced by the potential for major advances.
  • For applications involving human subjects, including clinical trials, evaluate the adequacy and feasibility of the plan to recruit and retain an appropriately diverse population of participants. Additionally, evaluate the likelihood of successfully achieving the proposed enrollment based on age, racial, ethnic, and sex/gender categories.
  • For clinical trial applications, evaluate whether the study timeline and milestones are feasible.
 

Investigator(s)

Evaluate whether the investigator(s) have demonstrated background, training, and expertise, as appropriate for their career stage, to conduct the proposed work. For Multiple Principal Investigator (MPI) applications, assess the quality of the leadership plan to facilitate coordination and collaboration.

Environment

Evaluate whether the institutional resources are appropriate to ensure the successful execution of the proposed work.

Specific to this NOFO: Evaluate whether the application describes a multidisciplinary team with expertise in microbiology and cancer research.Evaluate whether the team include expertise in relevant fields such as immunology, molecular or cellular cancer biology.
