Rare and paediatric cancers without markets

Any oncologist could send a difficult case, with the records, to a specialist centre and get a written expert opinion back within three days, free to the patient.

Cheap generic versions of targeted cancer drugs like imatinib exist, but patients with rare tumours carrying the matching mutation often cannot get them. A structured programme would treat them and collect the evidence.

Anyone diagnosed with a rare or complex cancer gets an automatic remote review by a specialist centre, paid for by the health system, before treatment starts.

Build a drug company that does not need profits, modelled on the ones that developed new tuberculosis and sleeping-sickness drugs, to take on rare, paediatric and undruggable cancers.

Children with cancer, and their families, need symptom relief and support from diagnosis, not only at the end. Every children's cancer unit should have a palliative team, and most in poorer countries have none.

Sometimes a trial cannot randomise, so the new drug is compared with past patients' records. Clear published rules on when that is allowed, and how it must be done, would replace case-by-case guesswork.

Rare cancers are often misdiagnosed, which sends patients down the wrong treatment path. Digital slide sharing could get every case to an expert within days.

Companies hold thousands of well-characterised drugs that could help rare cancers, but each request takes a year of legal negotiation. One standing agreement would unblock it.

Some drugs are approved for any cancer with a particular mutation. Clear rules on how many cancer types must be tested, and how to combine results across them, would make these approvals more consistent and faster.

Sometimes a treatment must be designed for a single patient. Agreeing in advance what evidence and safety checks are needed would make that fast, fair and learnable.

Doctors often use cancer drugs outside their approved use based on a hunch or a small study. Record what happens every time so the hunches become evidence.

Some drugs work on a genetic change whatever the cancer. When one regulator approves such a label, others should adopt it rather than demanding trials per cancer type.

Payers would promise in advance to buy a set number of doses at a set price for any drug that meets a defined bar in a rare or childhood cancer, so companies know the market exists before they invest.

Statistical methods can combine information across similar rare cancers to reach an answer with fewer patients. Regulators need to say in advance when that is acceptable.

Childhood cancers are rare, so no one country sees enough cases. Pool the treatment and outcome of every child treated anywhere into one governed dataset.

You cannot study a cancer without a laboratory model of it, and most rare cancers have none. A funded bank that makes and shares models would unlock research.

For many rare cancers there is not a single laboratory model in the world, so no one can test drugs. A shared bank with free distribution would change that.

When a company stops developing a cancer drug for business reasons, the rights and data would automatically be offered to charities and universities on set terms after two years, so promising compounds do not disappear.

A rare cancer drug designated 'orphan' in the US must reapply in Europe, Japan and elsewhere. Recognising each other's decisions would save small companies months.

Some sarcomas in children are caused by two genes fused into one abnormal protein. That protein is the whole disease, but no drug binds it. Destroying it instead of blocking it could work.

Children wait years for drugs because adult trials come first, even when the target belongs to a childhood cancer. Some drugs should start with children.

Companies often delay the childhood cancer studies they are required to do. A slice of the adult drug's revenue would be held back until the paediatric trial is completed.

Genetic test results for tumours are mostly PDFs. Require labs to also send a computer-readable version to a national store, so variants can be linked to what treatments worked.

Rare cancers often share a broken cellular machine even when they arise in different organs. Grouping patients by that shared fault makes trials possible.

Most children with cancer in rich countries are cured; most in poor countries are not, often because cheap drugs are missing. A global platform now ships quality drugs free; scaling it to 50 countries would be one of the highest-value cancer interventions available.

Instead of opening a trial at fifty hospitals and waiting for patients, keep a network of pre-vetted clinics ready and switch a trial on where a matching patient is found.

Teenagers with cancers that are really adult cancers, like melanoma or sarcoma, are barred from adult trials by an age line at 18. Letting them in from age 12, where biology and dosing allow, would give them access years earlier.

For very rare cancers, patients are scattered across countries. Patient-driven projects can gather records, saliva and tumour samples by post and share the data openly.

Join the national list of who got cancer to the genetic profile of each tumour, so we can see for the whole population which mutations matter and which drugs work for them.

Children's cancers are treated with combinations, but companies study new drugs in children one at a time. Approvals should require the combination study children actually need.

A patient with a rare cancer treated at a small hospital should have their case reviewed by the national experts by video before treatment starts. Make that referral automatic.

Cancer charities would fund companies to hit specific development milestones, as the cystic fibrosis charity did to create Kalydeco, and take a royalty they reinvest in the next drug.

Companies must agree separate plans for testing new cancer drugs in children with US and European regulators. A single agreed plan would get children access sooner.

Rare cancers are collectively common but each is too rare for normal trials. Link every rare cancer patient worldwide into one network with registries and trial designs built for small numbers.

Rare cancers are too uncommon for any country to learn from alone. Agree one set of rules so records from many countries can be combined.

Rare cancers together are a fifth of all cancers, but each is too small for its own trial. One permanent trial with many arms would give all of them a route.

For cancers too rare or too poor to attract companies, run drug discovery in the open, the way neglected tropical diseases are tackled, and take candidates to first human trials with public money.

No company can profit from a drug for a cancer that affects a few hundred people. A guaranteed payment for success would change that calculation.

Rare cancer patients are already tracked in registries. Offering randomisation inside the registry makes trials far cheaper and lets almost anyone take part.

When a trial has no comparison group, the comparison is sometimes built from old patient records. Set rules for how that is done so the answer is not rigged.

For very rare cancers there is often no genetic clue and no trial. Growing the patient's cells and testing drugs on them directly can suggest what to try.

The pathologist is the first person to know a cancer is rare or has a targetable marker. A rule in the lab system could notify a trial team at that moment, before treatment decisions close the window.

For rare cancers, the patient is often at a hospital that has no trial. A ready-made kit with the protocol, consent forms, database and shipping already set up would let that hospital enrol them within days.
