Outcome-based annuity payments for potentially curative one-time therapies

Instead of paying hundreds of thousands up front for a CAR-T or gene therapy, the health system would pay in yearly instalments that stop if the cancer comes back, so companies are paid for cures, not attempts.

Outcome-based annuities, already used for some gene therapies (for example spinal muscular atrophy and haemophilia contracts in Europe), applied systematically to cell therapies, bispecifics with curative potential and future one-time oncology treatments: payment spread over five years, each instalment contingent on the patient remaining in remission by pre-agreed criteria (imaging, MRD negativity). Payers gain risk-sharing; manufacturers gain higher total payment for real cures and a strong incentive to select patients well and improve durability. Needs a registry to adjudicate outcomes and accounting rules that let payers commit across years.

Hypothesis
Annuity contracts for CAR-T in lymphoma and myeloma lower payer cost per durable remission by at least 20% compared with up-front pricing, without reducing patient access, and manufacturers increase investment in durability (consolidation, MRD-guided retreatment) measurably.
Rationale
Contracts exist for Zolgensma and haemophilia gene therapies in several countries; oncology has cleaner outcome definitions (relapse) than many indications. Paying for outcomes corrects the current system where a therapy that fails at month six costs the same as one that cures.
What would test it
A national payer pilots annuity contracts for CAR-T in one indication with a registry-based remission adjudication, comparing cost per remission-year and access metrics against a control region with up-front pricing.

Bottlenecks it attacks
  • Incentives reward me-too drugs and marginal gains · The system pays the same for a drug that adds two months as for a cure, so companies race to copy rather than to cure.
  • Prices and value · New cancer drugs routinely cost over $150,000 a year, often for months of benefit. Systems cannot afford them and patients go bankrupt.
