A New Financial Instrument for Pediatric Oncology

The science exists. The financing doesn't.

Yellow Bonds convert philanthropic guarantees into revolving research capital. A $250M guarantee pool anchors a self-liquidating five-cycle issuance program, mobilizing more than $2 billion in research capital · without spending the guarantee.

It's not a science problem. It's a financing problem.

The pediatric oncology funding ecosystem is structurally misaligned. Government budgets are constrained by voting populations. Philanthropic capital is fragmented across thousands of organizations. The market will not fund what children need. Three data points frame the failure.

<4%
of NCI budget

Structural underfunding

Less than 4% of the National Cancer Institute's budget funds all childhood cancers combined.1 Fewer than ten drugs have been initially approved by the FDA specifically for a pediatric cancer indication.2 Adult cancers collectively receive more than 96% of NCI oncology research funding.

−24%
expected returns

Market failure

A 2019 JAMA Oncology analysis of 77 potential pediatric oncology projects found expected returns of approximately negative 24% on private-sector drug development.3 None could generate positive returns without philanthropic co-investment. Pediatric populations are too small to attract commercial capital without structural support.

30+ yrs
stagnant treatment

Three decades without progress

The MAP regimen · methotrexate, doxorubicin, cisplatin · has been the backbone of osteosarcoma treatment since the 1980s.4 No new first-line agent has achieved FDA approval for osteosarcoma in over three decades. Five-year survival for metastatic osteosarcoma remains below 30%.5

Credit-market discipline applied to childhood cancer.

Yellow Bonds borrow from proven blended finance frameworks. The structure applies the risk-layering and portfolio construction techniques of institutional credit markets to a domain that has relied on episodic, sub-scale philanthropic funding.

From one-time donation to revolving research engine.

Yellow Bonds are self-liquidating. A philanthropic guarantee anchors the structure · bond proceeds fund a diversified research portfolio · portfolio revenues repay par at maturity · the guarantee rolls forward. Four mechanical steps, five cycles, every cycle larger than the last.

01 · Commitment

Guarantee in Treasuries

Philanthropic capital commits to the guarantee pool and sits in AAA U.S. Treasuries, earning yield. Capital is not disbursed · it serves as first-loss credit enhancement, called only if portfolio revenues fall short of par at maturity.

02 · Deployment

Scale enables diversification

Bond proceeds deploy across a large portfolio of pediatric oncology research projects · diversified by disease subtype, development stage, therapeutic modality, and geography. Peer-reviewed, milestone-tranched, portfolio-governed.

03 · Repayment

Portfolio revenues repay par

The research portfolio generates revenue through royalty licensing, milestone payments, Priority Review Vouchers (worth $100-150M each), platform technology licensing, and therapeutic sales. Accumulated revenues are designed to repay par at maturity · without calling the guarantee.

04 · Recycling

Declining coverage, growing impact

The guarantee pool remains intact across cycles. As portfolio data seasons and governance matures, coverage requirements decline · 50% (Series A) to 30% (Series E). The same $250M backs progressively larger bonds, compounding deployment without new philanthropic capital.

Why scale is structural
More par. More projects. Higher repayment probability.
A $500M par bond funds 80-120 research projects · enough to convert single-project binary outcomes into a portfolio distribution of returns. The larger the portfolio, the tighter the distribution around the expected value, and the more probable that aggregate revenues cover par at maturity. Diversification is not a feature of Yellow Bonds · it is the mechanism that makes institutional repayment probable and earns the investment-grade rating.

Proceeds calculated at 4.5% yield on 10-year zero-coupon issuances with par totaling $3.23B across the five series. Treasury yield reflects ~4% on the $250M pool across the issuance horizon. Declining coverage is earned, not asserted · by Series C, the program has a decade of portfolio performance data, governance track record, and potentially a rating history that support tighter structural terms on each successive issuance.

This is not a novel invention.

Yellow Bonds are a novel combination of proven components. Each structural element has been validated at scale in adjacent domains.

Mechanism
Scale
Parallel to Yellow Bonds
Green Bonds Labeled-bond category
$2.5T+ cumulative6 Since 2007
Green Bonds created an entirely new asset class through earmarked bond proceeds for environmental projects. The labeled-bond framework · ICMA principles, transparent use of proceeds, third-party verification · is the template Yellow Bonds follow for pediatric cancer research.
IFFIm · Vaccine Bonds Sovereign-backed health finance
$10.2B raised7 1B+ children immunized
The International Finance Facility for Immunisation has issued over $10B in vaccine bonds since 2006, backed by legally binding sovereign pledges. Purchased by central banks, pension funds, and retail investors. Yellow Bonds apply the same guarantee-to-bond mechanism to pediatric oncology research.
Royalty Pharma Model Revenue-based financing
$24.6B deployed8 2020-2024 · 33% CAGR
Synthetic royalty financing is an established asset class with mature pricing models. The Yellow Bond revenue model · royalties, milestone payments, priority review vouchers, licensing receipts · directly mirrors the structures that have made royalty-backed pharmaceutical financing a $24B+ market.
Cystic Fibrosis Foundation Direct philanthropic precedent
$150M → $3.3B9 Venture philanthropy recycling
The Foundation invested $150M in therapeutic development, returned $3.3B through commercial licensing, and reinvested the proceeds. Yellow Bonds bring this same recycling principle to childhood cancer · through a public-market instrument rather than a private venture portfolio.

Capital that compounds impact.

Yellow Bonds convert philanthropic intent into institutional-grade capital deployment. The guarantee is a structural commitment, not a disbursement.

$1 mobilizes ~$9 of research capital

Across five cycles with declining coverage and Treasury yield on the pool, every dollar of guarantee underwrites approximately nine dollars of deployed research capital · a 9× multiplier. This leverage is not available through direct grantmaking.

Your capital stays invested

The guarantee sits in AAA U.S. Treasuries, earning yield. It is a contingent liability, not a cash outlay · called only if portfolio revenues fall short. For foundations and DAFs, this is capital-efficient use of balance sheet assets.

PRI-eligible structure

The guarantee structure qualifies as a Program-Related Investment for private foundations · counting toward the 5% minimum distribution requirement while preserving principal. DAF sponsors can commit under mission-aligned investment policies.

Institutional governance

Independent SPV trustee, Big 4 audit, quarterly reporting to all stakeholders, scientific advisory board governing portfolio construction. Guarantors hold board representation on the governing entity with full impact reporting.

The Ask

Seeking 3-5 anchor foundation commitments to form the guarantee pool.

Smaller commitments are welcomed alongside anchor capital. The structure accommodates a range of guarantor sizes · from anchor foundations and sovereigns to DAFs and family offices · provided the aggregate pool reaches target size.

An experienced team. A community mission.

Yellow Bonds are being developed at the intersection of structured finance and pediatric oncology research funding. The team is resourced to design, issue, and govern the instrument at institutional standards, supported by pediatric oncology clinicians and capital-markets counsel.

But Yellow Bonds are not a product. They are the beginning of a coalition · foundations, donor-advised funds, sovereigns, institutional investors, research institutions, clinicians, and patient advocates aligning around a new way to fund childhood cancer research at scale.

The goal is not a single bond. The goal is to fundamentally and sustainably change how childhood cancer research is financed · replacing episodic, fragmented grantmaking with a revolving institutional mechanism that matches the scale of the science and the duration of the need.

The structure makes the coalition investable. The coalition makes the change permanent.
