Find a clinical trial

What is a clinical trial? (and why you shouldn't be afraid)
Voluntary and safe
Participation is always voluntary. You can leave at any time. Every trial is approved by an ethics committee that protects participants.
You receive close medical supervision
Trials follow strict phases. You receive treatment (often in addition to the standard one), with closer monitoring than usual.
Access to new therapies
Many of the most promising advances in glioblastoma are only available through trials. Asking about them is always worthwhile.

What to do next

1
Select and take notes Check the box to select a trial. Use the pencil to jot down questions or notes. Then hit Print — your selection and notes will be ready to share with your doctor.
2
Talk to your neuro-oncologist Bring the study to your next appointment. Your team can check whether you meet the eligibility criteria and how to enrol.
3
Ask without fear There are no silly questions. Ask about benefits, risks, travel, costs and timeline. It's your right.

The part nobody explains

What if the trial is in another region?

You cannot enrol on your own: it always goes through your hospital. These are the three things worth asking for from day one — asking early is what saves weeks.

Ask your neuro-oncologist, in writing
The referral to a centre in another region is requested by your medical team, not by you. Ask them to put the request in your record, so it leaves a trace and can be followed up.
Ask for the tumour tissue block
Almost every trial needs a sample of your tumour, and getting the block released from pathology takes weeks. Requesting it before you need it is the single biggest time-saver.
Ask what is covered and what is not
The trial sponsor normally covers the study’s own tests and treatment. Travel and accommodation usually are not — and conditions vary between regions. Ask before you decide, not after.

If your hospital cannot take it forward, in Spain you can ask for a second opinion and for referral to a reference centre: we explain how, step by step, in Second opinion and referral →. Outside Spain the procedure is different and depends on each health system — ask at your own hospital.

Featured studies worth knowing about

An overview of treatment approaches under investigation — what each one is and why it matters. Educational content, not a recommendation.

We deliberately do not state phase or recruitment status here, because they change: each link opens the live studies in the official registry. Content reviewed:

Other places to search

Our finder queries ClinicalTrials.gov and REec live. Coverage of the European registry is still partial, so these are worth a look by hand as well.

REec En vivo en nuestro buscador

Spanish Registry of Clinical Studies (AEMPS). Our finder queries it live: it is the only registry that carries Spanish academic trials.

Open REec → EU CTIS En vivo en nuestro buscador

European Clinical Trials Information System: the unified registry for every trial authorised in the EU. Our finder queries it and brings back the ongoing and authorised ones; open it here to see closed trials too, or to search it yourself.

Open EU CTIS → ClinicalTrials.gov En vivo en nuestro buscador

The world's largest public registry. Our finder queries it in real time.

Open ClinicalTrials.gov → WHO ICTRP Consulta a mano

WHO platform that aggregates 17+ national registries worldwide. If a trial isn't on ClinicalTrials.gov, it may be here. It publishes no open search service, so it has to be searched by hand.

Open WHO ICTRP → EORTC Brain Tumour Group Consulta a mano

European Organisation for Research and Treatment of Cancer. Runs multicentre brain tumour trials across Europe. Not a registry but the sponsor: its trials appear in the registries above, and its site adds the group's own detail.

Open EORTC → ISRCTN Consulta a mano

International registry recognised by WHO and ICMJE. Many European trials (especially UK) are registered here. No open search service: search it by hand.
