Grantmaking involves balancing the potential impact of a successful research project with the risk of experimental failure. Traditionally, risk mitigation is accomplished during the research proposal review process in several ways, including heavily weighing preliminary data. While the historical balance point has proven broadly effective and successful, the stubborn lack of progress in osteosarcoma suggests that alternatives should be considered. Thus, the aim of this grant program is to place less emphasis on preliminary data in order to encourage projects exploring bold innovations that may fall within any stage of the drug development path, and that seek to deliver curative outcomes to patients with osteosarcoma. Proposals will be most valued based on their innovation and sound scientific hypothesis, and the likelihood that the approach will address a true dependency in osteosarcoma.
The desired criteria for this high-risk/high-impact osteosarcoma drug development research are:
• Bold ideas that will generate evidence of success or failure within 12 months.
• A new research direction rather than a continuation of ongoing funded research.
• While preliminary data are not required, the applicant must demonstrate feasibility of a persuasive research plan.
• Rigorous, quarterly interactive grant progress reviews to be used to guide ongoing direction and distribution of research support. A successful high-risk/high-impact grant proposal should have one or more of the following characteristics:
• A proposal that, upon successful conclusion of the project, may mature into a successful submission for a traditional OSI grant or launch a translational development plan with investigators, institutions, or commercial biopharma companies.
• An existing relationship that makes the development of a therapeutic asset in biopharma feasible.
BUDGET From $25,000 – $125,000 total over one year (inclusive of indirect costs not to exceed 10% of the requested project budget).
OSI exclusively funds projects that meaningfully accelerate treatments, particularly for:
Relapsed or refractory osteosarcoma
Metastatic disease (especially lung metastasis)
Therapeutic resistance and relapse biology
Clinically actionable targets
Priority topics include:
Immunotherapy (T/NK cell, vaccines, IO combinations)
Target discovery & validation
Drug repurposing or novel small molecules
Precision medicine strategies (genomic, proteomic)
Biomarkers predicting response or relapse
Minimal residual disease (MRD) and monitoring tools
Metastasis inhibition
❗ Basic bone/sarcoma biology without a clear therapeutic implication rarely gets funded.
OSI offers mechanisms aligned to translational stage:
| Mechanism | Best For | Key Criteria |
|---|---|---|
| Clinical Trial Grants | Investigator-initiated OS trials | Patient access, delivery timeline, safety & endpoints |
| Translational Grants | Bridging lab → clinic | Strong preliminary data + clear therapeutic pathway |
| Drug Development / Accelerator Funding | Industry or academia–industry | IND-enabling or near-clinical compounds |
Predictor: Match your development stage to the mechanism: discovery → validation → translation → trial.
OSI expects feasibility evidence:
Target expression/essentiality
Early efficacy in OS models
Pharmacokinetic/toxicity data (if drug-focused)
Proof of access to relapsed OS cohorts or samples
Pilot biomarker signals
Predictor: Strong preliminary data is a top determinant of success.
Models must clearly reflect human OS disease:
Patient-derived xenografts (PDX)
OS lung metastasis models
Canine OS as a translational bridge
CRISPR or humanized OS models
OS organoids or 3D cultures
Omics-driven subtype stratification
Predictor: OS-specific and metastasis-relevant models are critical for translational value.
Winning proposals articulate a stepwise path toward patient benefit, including:
Defined translational milestones
Criteria for progressing to clinical trial
Endpoints that enable FDA engagement
Roadmap for CMC, toxicity, patient accrual (if applicable)
Predictor: “Therapy acceleration” must be undeniable.
Especially for clinical/translational awards:
Access to relapse and metastatic patients
Clinical sample biobanks
Imaging/pathology data
Partnerships with COG/SARC groups or major sarcoma centers
Predictor: Demonstrated access to relevant patients boosts feasibility.
Top-scoring proposals include:
Clinician–scientist involvement
Experts in drug development, immunology, or metastasis biology
Cross-institutional collaborations
Industry partnership for IND/CMC/trial readiness
Predictor: Proven expertise + collaboration improves reviewer confidence.
OSI funding is milestone-driven.
Best proposals have:
2–3 focused, hypothesis-driven aims
Concrete deliverables (e.g., “IND submission-ready PK/PD dataset”)
Risk mitigation strategies
Clear timelines & go/no-go checkpoints
Predictor: Clarity + feasibility = higher scores.
Highest priority for:
Relapsed/refractory disease
Rare OS subtypes
Therapies for patients with limited options
Early detection of metastasis or relapse
Reducing treatment toxicity in young patients
Predictor: Targeting urgent care gaps strengthens impact.
Reviewers appreciate proposals that are:
Direct and well-written
Supported by compelling figures
Easy to follow for clinicians, scientists, and drug developers
Strong in statistical and regulatory rationale (if clinical)
Predictor: Professional-quality writing improves enthusiasm.
| Predictor | Why It Matters |
|---|---|
| Osteosarcoma-specific focus | Core mission |
| Mechanism alignment | Expected progress level |
| Strong preliminary data | Demonstrates feasibility |
| Relevant OS models | Ensures translational relevance |
| Near-term clinical trajectory | OSI’s core goal |
| Patient access | Critical for clinical translation |
| Collaboration | Execution & expertise assurance |
| Focused aims | Fits OSI’s milestone-driven model |
| Address unmet needs | Aligns with mission urgency |
| Clear writing & rationale | Improves reviewer scoring |
• Funds must be granted to nonprofit/charitable institutions or organizations. While we allow for any individual institution to submit multiple LOI submissions, we are unlikely to fund more than one grant per institution in any grant cycle.
• Grantee organization does not need to be based in the United States.
o However, in order to fund a foreign entity, the OSI requires documentation that if the entity were a United States-based organization, the entity would qualify as a charitable organization. This is usually relatively straightforward when dealing with entities in countries with a tax regime similar to the U.S. by way of a government-issued letter or other document designating the entity as a charitable institution or as performing a charitable purpose (for example, research or education). It might also be a determination from the relevant taxing authority that the entity qualifies for tax-deductible contributions.
• Applicants need not be United States citizens.
• Applicants must have an MD, PhD, MD/PhD, or equivalent and be appointed as faculty (or equivalent) at an academic institution.
• Applicants must have a track record of publication and funding productivity that demonstrates the project can be accomplished by the investigators.
• Research projects may be an extension of ongoing research but cannot overlap with any funded studies unless the applicant clearly demonstrates that new funding will not duplicate existing support.
• Applicants can submit only one (1) Letter of Intent (LOI).
• Applicants selected for funding will permit the OSI to publicize the grant for fundraising purposes, including, but not limited to a five-minute video discussing the research project, photos of lab, and photos of children participating in clinical trials, where applicable.
• Applications that do not follow the specific grant application instructions and/or submission process will not be considered.
• Applications received after the due date will not be considered.
• Applications which do not fall under the OSI mission will not be considered.
• Resubmissions: Only one resubmission of a previously reviewed application is permitted.
