This Request for Proposals (RFP) seeks to identify investigators with innovative research proposals who are interested in partnering with Pfizer and potentially other likeminded investigators on co-developing research studies focused on understanding the burden of Clostridioides difficile (C. difficile) infections in humans. Researchers selected from this RFP will work in collaboration with the Pfizer medical team to co-develop a research project, study protocol, and publication in peer-reviewed medical literature. In all selected studies the investigator will serve as the principle investigator and the regulatory sponsor of the study.
Geographic Scope
France, Germany, Japan, United Kingdom, United States
Key Milestones
Application submission deadline: 11 December 2025
Anticipated decision notification date: February 2026
Anticipated project start date: 1 April 2026
Funding Range and Project Length
Individual projects requesting up to $500,000 USD will be considered. Maximum project length is 12 months
| Predictor | Why It Matters | Evidence / Typical Pattern |
|---|---|---|
| Strong alignment with Pfizer’s therapeutic priorities | Pfizer funds research in areas directly linked to its portfolio (oncology, vaccines, inflammation, rare disease, immunology, internal medicine, cardiology). | Projects matching open RFP focus areas (e.g., breast cancer, COVID-19, IBD, hemophilia) have much higher success rates. |
| Scientific quality and rigor | Reviewers prioritize hypotheses with strong rationale, robust design, and measurable endpoints. | Funded IIRs include detailed protocols, power analyses, and statistical plans. |
| Feasibility and investigator capability | Applicants must demonstrate ability to deliver — through experience, facilities, and institutional support. | Past awardees often have prior industry collaborations or clinical trial experience. |
| Innovation and potential for impact | Pfizer favors novel concepts that could advance standard of care, generate real-world evidence, or improve patient outcomes. | “Innovative, practice-changing” is a core review criterion in Pfizer GMG guidelines. |
| Patient-centered outcomes and real-world relevance | Research must show how findings will improve clinical practice, patient experience, or access to care. | RWE (real-world evidence) and implementation science projects score highly. |
| Ethical and regulatory compliance | Proposals must follow ethical standards, IRB review, and independent data control. | Transparency and compliance are non-negotiable; weak governance leads to disqualification. |
| Interdisciplinary collaboration | Pfizer encourages academic, clinical, and community partnerships to ensure broad impact. | Multi-institutional or multidisciplinary proposals are more competitive. |
| Clear dissemination plan | Pfizer seeks measurable deliverables — peer-reviewed publications, conference presentations, or practice guidelines. | Reviewers favor well-defined post-grant dissemination timelines. |
Weak or indirect connection to Pfizer’s active RFP topic or disease area
Lack of innovation or incremental proposals duplicating existing data
Overly ambitious scope with limited timeline or budget
Insufficient methodological detail (missing endpoints, unclear sample size)
No clear path to clinical application or educational outcome
Incomplete documentation (missing budgets, institutional letters, compliance info)
Pfizer Global Medical Grants: success rate ≈ 10–15%, depending on competition and RFP topic.
IIR Grants: ~15–20% for experienced investigators with strong institutional support.
Education Grants (IGLC): 20–25%, depending on geographic region and therapeutic focus.
Alignment with Pfizer’s defined therapeutic priorities
Strong study design and feasibility
Innovative and practice-changing potential
Patient-centered, measurable outcomes
Experienced investigator and supportive research environment
The institution and Principal Investigator (PI) must be based in one of the eligible countries.
• Only organizations are eligible to receive funds and in-kind support, not individuals or medical practice groups (i.e., an independent group of physicians not affiliated with a hospital, academic institution, or professional society).
• If the project involves multiple departments within an institution and/or between different institutions / organizations / associations, all institutions must have a relevant role and the requesting organization must have a key role in the project.
• The PI must have a medical or postdoctoral degree (MD, PhD, or equivalent), an advanced nursing degree (BSN with a MS/PhD), or a degree in Pharmacy, Physiotherapy, or Social Work.
• The applicant must be the PI or an authorized designee of such individual (e.g., PI’s research coordinator).
• The PI must be an employee or contractor of the requesting organization.
• If selected, the PI and their organization are willing and able to engage in a Research Collaboration with Pfizer; see definition of ‘Research Collaboration’ further down for details.
• For all Research Collaborations (RCs), the grant requester (and ultimately the grantee) is responsible for the design, implementation, sponsorship, and conduct of the initiative supported by the RC, including compliance with any regulatory requirements. Pfizer may be involved in the design of the study protocol and project development, as well as the conduct or monitoring of the research program. Preference will be given to PIs that are open to collaborative agreements with other institutions with similar research interests.
• Requesting organization must be legally able to receive award funding directly from Pfizer Inc. We strongly recommend that applicants confirm this with their organization or institution prior to submitting an application. Funding awarded to organizations that are subsequently found to be unable to accept funding directly from Pfizer Inc. may be cancelled.
