Motion: This report argues that a £90,000 Alzheimer's drug breakthrough may still fail patients on real-world benefit and access. Judy, begin with the case for or against pursuing this kind of treatment strategy.

The strongest case for this strategy is obvious: Alzheimer’s is devastating, and any therapy that slows decline looks worth funding. But the claim that a £90,000 drug is a real breakthrough for patients has a glaring flaw: it confuses lab signal with public benefit. If the effect is marginal, hard to access, and tied to repeated scans and infusion capacity, the bottleneck is the system, not just the molecule. England already rationed similar Alzheimer’s drugs in 2024 over cost-effectiveness concerns. A treatment that only affluent systems can deliver at scale does not solve inequality, it weaponizes it. What exactly is being ‘broken through’ here, science or pricing power?

You argue that a £90,000 drug is not a real breakthrough because access is limited and England rejected similar drugs in 2024. Fine, that is the strongest version of your case: cost and delivery matter. But the flaw is a false equivalence between rollout failure and scientific failure. A treatment can be clinically meaningful before a health system learns how to fund and target it. CAR-T therapies looked impractical too, then systems adapted. The real question is whether slowing decline by even months reduces care burden. If trials show that, rationing is a policy defect, not proof the treatment is worthless.

Your strongest point is that rollout failure is not scientific failure, and yes, a drug can work before systems catch up. But that dodges the core flaw: no causal link between a narrow trial effect and population benefit. CAR-T is a bad analogy because it targets specific cancers with dramatic responses; Alzheimer’s monoclonals have shown modest slowing, not reversal, while adding scan, infusion, and safety burdens. In 2024, NICE rejected similar drugs partly because the benefit was too small for the cost. If a treatment buys a few months for a tiny eligible slice while draining public budgets, that is not a breakthrough, it is rationed symbolism. Who exactly benefits at scale?

Your strongest claim is that a drug giving only modest slowing for a small eligible group can drain public budgets without helping patients at scale. Fine. But the flaw is a false threshold: you treat anything short of reversal or mass rollout as mere symbolism. That is not how medicine works. Early HIV therapy was toxic, narrow, and expensive in the late 1980s, yet it still mattered because incremental gains changed the trajectory of care. If an Alzheimer’s drug delays institutionalization by even 6 to 12 months for a defined subgroup, that changes family burden, care costs, and treatment incentives immediately. Breakthroughs start narrow. Systems scale later.

Your strongest claim is that 'breakthroughs start narrow' and even a 6 to 12 month delay in institutionalization could matter. Sure, incremental medicine exists. But that argument cherry-picks a best-case subgroup and smuggles in an unproven outcome. Delaying decline in a trial is not the same as delaying institutionalization across real health systems with MRI monitoring, infusion slots, and serious safety screening. NICE rejected comparable Alzheimer’s drugs in 2024 because the benefit was too small for the cost. When a therapy costs £90,000 before delivery overheads, public money gets diverted from broader dementia care, staffing, and support that help far more patients. Narrow for whom, and at whose expense?

Your strongest point is that a £90,000 therapy can crowd out wider dementia care if real-world delivery stays narrow. Fine. But the flaw is cherry-picking static system limits as if capacity never changes. NICE’s 2024 rejection was a reimbursement judgment, not proof the drug lacks value. New treatments force systems to build MRI, infusion, and diagnostic pathways, and that spillover raises standards for future patients too. If a defined subgroup gets even 6 months of slower decline, that affects carers, care-home timing, and planning immediately. Do you want health policy to reward only cheap maintenance, or actual innovation?

Your strongest point is that new drugs can force systems to build capacity and that even 6 months of slower decline could matter for carers. Fine. But that claim has a missing enforcement mechanism: it assumes expensive innovation automatically creates equitable access rather than premium bottlenecks. In England, NICE rejected similar Alzheimer’s drugs in 2024 precisely because marginal benefit did not justify the cost. Building MRI and infusion pathways around a £90,000 drug means scarce staff and public money get pulled toward a narrow cohort while millions living with dementia need basic support now. That is not system progress, it is inequality dressed up as innovation. Why should patients subsidize pharma pricing theater?

Your strongest point is that expensive innovation can create premium bottlenecks instead of equitable access. Fine. But the flaw is treating NICE’s 2024 cost-effectiveness ruling as proof the policy goal should be basic support over frontier treatment, which is a false dilemma. Health systems have to do both. The UK already built high-cost pathways for cancer and rare disease drugs because early capacity matters. If this therapy slows decline even modestly in biomarker-confirmed patients, that creates measurable value in care planning and delayed dependency. A £90,000 launch price is a negotiation problem, not an argument against building capability.
