Manufacturing cost and time for living and radioactive medicines

A handful of ageing research reactors make most cancer isotopes. Coordinating their maintenance and funding reserve capacity would prevent the shortages that stop treatments.

Nobody publishes how much cancer isotope is made, where, or when supply will fall short. A public observatory would let hospitals and investors plan.

Patients wait weeks for a manufacturing slot while other slots go unused when a patient drops out. A shared booking system would match spare slots to waiting patients.

Most new cancer imaging agents and radioactive drugs start in university hospitals. A network sharing production, quality files and regulatory paperwork would get them into multi-centre trials years faster.

Each cell-therapy machine uses its own proprietary process and cartridges. A common standard would let a process run on any machine, like a document opening in any word processor.

The lutetium used in approved prostate and neuroendocrine cancer treatments is made from an enriched metal that comes mostly from Russia. Making it elsewhere would secure supply.

By the time patients need CAR-T their immune cells are often exhausted by earlier treatment. Storing healthy cells early would improve manufacturing success and cut the wait.

Improving how a cell therapy is made currently risks having to repeat clinical trials. A validated computer model plus a fixed set of product measurements would let changes be approved on data alone.

The poisons carried by antibody-drug conjugates are so toxic that only a few factories can make them, and they are booked years ahead. Making them in small continuous reactors would ease the bottleneck.

Cell therapy batches fail more often than any other medicine, partly because each patient's cells behave differently. Sensors and software that adjust the process in real time could rescue many of them.

Health systems would pay for a $400,000 cell therapy only if it works. If the cancer has not responded by three months, the company refunds the price.

Almost every alpha cancer therapy in development relies on one scarce isotope. Developing several alternatives at once would stop the whole field waiting on a single supply chain.

Spain lets hospitals make and use their own CAR-T under a special rule; most European countries do not. A common rule with shared outcome tracking would spread affordable academic products.

Academic hospitals can already make CAR-T cells for a fraction of the commercial price. A public network would scale that so more patients can be treated for less.

European law already lets hospitals make advanced therapies for their own patients. Pair that with a shared outcomes registry so academic CAR-Ts and similar treatments can prove themselves without a commercial licence.

Instead of shipping a patient's cells to a distant factory, hospitals would make CAR-T on site under a shared licence, cutting cost and waiting time.

Some new medicines reprogramme immune cells inside the body with an injection, skipping the factory entirely. Test whether that makes CAR-T affordable and available in ordinary hospitals.

Instead of making cell therapy from each patient's own cells in a factory, inject a particle that reprograms immune cells inside the body, made in bulk, so a dose costs thousands rather than hundreds of thousands.

Patients and doctors cannot see how long each CAR-T maker takes or how often manufacturing fails. Publishing this would create pressure to get faster and more reliable.

Changing how a cancer drug is made must be approved separately in over a hundred countries, which takes years and causes shortages. One approval should count for all.

Factories making living or radioactive cancer medicines are inspected separately by each country. Accepting each other's inspections would free up inspectors and speed supply.

The engineered virus that delivers the CAR gene costs tens of thousands of dollars per patient and is controlled by a few suppliers. A non-profit supplier with open licences would cut that cost sharply.

Putting the CAR gene into T cells without a virus removes the most expensive and delay-prone ingredient. Test whether non-viral products match viral ones.

Donor immune cells that need no matching could be given as short courses to clear the few cancer cells left after surgery, when the target is smallest.

Engineered immune cells given by drip rarely reach brain tumours. Briefly opening the barrier with focused ultrasound at the right moment may let them in.

A single cell therapy can cost more than a house. Paying in yearly instalments, only while the patient stays well, spreads the cost and shares the risk.

Custom cancer vaccines take weeks to make and work best when there is very little disease. Making one at surgery and giving it when a blood test turns positive matches both facts.

Cell therapies fail when the tumour stops showing the marker they were built to find. Preparing an alternative product in advance would let doctors switch quickly.

Many antibody-drug conjugates share the same linker and payload chemistry. Regulators should let companies reuse the manufacturing evidence rather than repeating it for every new antibody.

Building a cell-therapy factory costs tens of millions, so most good academic ideas never reach patients. Shared public facilities would give them a route to the clinic.

Hospitals in Spain make their own CAR-T for a third of the commercial price. Paying for such products at cost gives health systems a lever in negotiating with companies.

There is no agreed ruler for measuring how strong a CAR-T product is. Shared reference materials would let hospitals, companies and regulators compare products fairly.

India has shown CAR-T can be made for a tenth of the US price. Public production in large middle-income countries could make it available to millions who are currently excluded.

Cell therapies made from a single stem cell line could be produced in bulk. Regulators should let companies certify the parent cell line once rather than repeating it for every product.

Thousands of old radium sources sit in hospital and industrial storage. They are exactly the raw material needed to make actinium-225, the scarcest cancer isotope.

Actinium-225 can be made in particle accelerators, but the product contains a trace of a long-lived impurity that regulators have not agreed how to handle. Settle the limit and build the hubs.

Radioactive cancer drugs decay while they travel and get stuck at borders. Regional production and simpler transport rules would get more doses to patients on time.

Build a handful of publicly-funded centres where academic discoveries can be manufactured to clinical grade and written up for regulators, so good ideas do not die for lack of a factory and a filing.

Growing a patient's own tumour-fighting cells only works if those cells are there to start with. A test for them would spare futile treatment.

Personalised cancer vaccines and cell therapies need a factory for each patient. Shared, automated production units serving many academic hospitals would let universities run these trials without building their own plants.

CAR-T can now be made in a day or two, but the safety tests to release it still take two weeks. Faster tests would let patients be treated within days.

Cell therapies are tested for purity and count, but not for whether they can actually kill that patient's tumour. Testing them against the patient's own mini-tumour would show this.
