Overview
The Ehlers-Danlos Society is seeking proposals focused on the development, validation, and evaluation of objective diagnostic approaches for Mast Cell Activation Syndrome (MCAS).
This funding opportunity was developed in response to ongoing challenges surrounding the identification, classification, and clinical characterization of MCAS, particularly within populations affected by Ehlers-Danlos syndromes (EDS), hypermobility spectrum disorders (HSD), and related multisystem conditions. Current diagnostic pathways remain inconsistent, clinically burdensome, and often inaccessible due to limited sensitivity, transient biomarker availability, lack of standardized testing approaches, and variability in diagnostic criteria used across clinical settings.
The goal of this RFA is to support scientifically rigorous studies that advance the development of clinically meaningful, objective, and reproducible diagnostic strategies for MCAS. We are particularly interested in studies investigating biomarkers and clinical and laboratory-based diagnostic tools that improve patient stratification and enrollment criteria, support future therapeutic development, facilitate clinical trial readiness, that improve patient stratification and enrollment criteria; support future therapeutic development; and facilitate clinical trial readiness and clinical practice.
Applicants are encouraged to propose innovative, practical, and translational approaches that may help define homogeneous patient populations, improve diagnostic specificity and sensitivity, and contribute to the broader understanding of mast cell-related disease mechanisms. The goal would be the identification and or confirmation of highly sensitive and specific diagnostics from easily accessible tissue (i.e., blood, urine, etc.). The Society welcomes multidisciplinary collaborations involving clinicians, translational researchers, immunologists, laboratory scientists, and diagnostics experts.
This RFA is intended to support early-stage and pilot research capable of generating foundational data for larger-scale future studies, industry partnerships, and therapeutic development efforts.
Funding Amount Overview
- Total anticipated funding: ~$300,000 USD
- Individual awards may vary based on project scope, feasibility, and scientific merit
- Pilot studies and early-stage validation studies are encouraged; confirmatory studies of existing MCAS analytes preferred
- Smaller proof-of-concept studies involving focused cohorts (e.g., 20–30 participants) are acceptable where scientifically justified
Future expanded funding opportunities may be considered for highly successful pilot projects that demonstrate strong preliminary findings and clear translational potential.
Research Priorities and Areas of Interest
Applications should align with one or more of the following priority areas:
1. Development of Objective Diagnostic Approaches for MCAS
Studies focused on identifying and validating objective methods for defining MCAS patient populations, including but not limited to:
- Molecular or immunologic signatures
- Multi-analyte diagnostic panels
- Novel mast cell mediator assessment approaches
- Objective laboratory correlates associated with mast cell activation
- Biomarker combinations with improved sensitivity/specificity profiles
Potential analytes discussed during program development included but were not limited to:
- Histamine metabolites
- N-methylhistamine
- Tryptase
- Leukotrienes
- Prostaglandins
- Chymase
- Heparin
- Additional mast cell mediators or inflammatory markers
2. Identification of Clinically Meaningful Patient Stratification Approaches
Studies aimed at improving identification of clinically relevant MCAS subgroups including:
- Defining homogeneous patient populations suitable for future clinical trials
- Correlating objective biomarkers with symptom burden or multisystem involvement
- Investigating biological heterogeneity within MCAS populations
- Evaluating potential disease or mediator-dominant phenotypes
Applicants may explore whether distinct biological or mediator profiles exist across patient populations.
3. Biomarkers Associated with Disease Activity or Treatment Response
Applications may include exploratory approaches evaluating biomarkers that could potentially:
- Correlate with disease activity
- Track mast cell reactivity over time
- Support treatment monitoring
- Serve as clinical trial endpoints
Applications proposing clinically practical, scalable, or patient-accessible approaches are strongly encouraged.
4. Translational and Clinical Feasibility Studies
The Society is particularly interested in projects that consider future clinical usability and scalability, including:
- Feasibility of implementation in clinical/laboratory settings
- Accessibility and cost considerations
- Potential diagnostic commercialization pathways
- Clinical reproducibility
- Utility within interventional trials
Areas of Encouragement
The Society strongly encourages:
- Multidisciplinary collaborations
- Translational and clinically applicable research
- Pilot and proof-of-concept studies or, better yet, confirmatory studies
- Studies leveraging existing patient cohorts or biospecimens
- Innovative diagnostics methodologies
- Inclusion of experts in immunology, allergy, laboratory medicine, and translational diagnostics
- Studies with clear future scalability potential
- Research incorporating clinically meaningful outcome measures
- Studies that carefully identify the sensitivity and specificity of the approach
Eligibility
Applications are welcome from academic institutions, hospitals and medical centers, nonprofit research organizations, independent research institutes, for-profit groups, and multidisciplinary collaborative teams with relevant expertise in mast cell biology, immunology, translational diagnostics, or related fields. Both U.S.-based and international applicants are eligible to apply.
Detailed Eligibility Requirements
Applicants should demonstrate:
- Relevant expertise in mast cell biology, immunology, allergy, translational diagnostics, laboratory medicine, or related disciplines
- Access to appropriate patient populations and/or biospecimens
- Feasibility of completing the proposed work within the proposed timeline and budget
- Appropriate institutional support and ethical oversight
Funding Restrictions
Indirect Costs (IDC) are capped at 5% and must be included within the total amount requested in the proposed budget.
Expected Deliverables
Funded investigators will be expected to provide periodic scientific progress updates, interim findings summaries, and a final written report outlining study outcomes, methodologies, and key findings. Investigators should also provide relevant data related to biomarker validation or diagnostic performance, along with recommendations for future development and translational considerations where applicable. Publications and dissemination plans should be included when relevant. Additional reporting requirements will be outlined within the final award agreements.
Anticipated Timeline
- Research Funding Announcement: July 3, 2026
- Full Application Deadline: August 14, 2026
- Internal Review Period: August 17 – 21, 2026
- Scientific Review Period: August 24 – September 11, 2026
- Notification to Applicants: By September 18, 2026
Important Considerations
Applicants should note:
- The Society recognizes ongoing debate and variability surrounding current MCAS definitions and diagnostic approaches.
- Applications may propose varying scientific approaches provided methodologies are rigorous, evidence-based, and scientifically justified.
- The Society remains open to diverse scientific hypotheses and encourages data-driven research approaches.
- Proposed studies should avoid overly broad or poorly defined patient populations unless appropriately justified.
