Cancer FAQs


How do you look for trials that match my diagnosis?

The system screens the international ( and national (REEC) databases of cancer clinical trials based on your diagnosis and the inclusion and exclusion criteria of the trials.

Can I put in more than one query?

Yes, users can enter more than one queries. In that case, the app will filter the cancer trials by the query selected.

Is there only cancer clinical trials?

MatchTrial will only have cancer clinical trials in a first phase, but later it will incorporate other pathologies.

How can I apply to participate in a clinical trial?

Once the search is finished, go to the clinical trial you want to participate in to access all the information. – If it appears “I want to participate” you can choose the centre and our Patient care team will contact you to schedule the appointment. – If it appears “Ask for information” by choosing the centre you will see the contact information. This happens for the trials that have not hired our patient care service.

Security and data

What happens with my data?

The data entered in the application are registered in the system and are only shared with those sites where participation in a clinical trial is requested.

Is my data safe?

All data is encrypted and managed according to Organic Law 3/2018, of December 5, on the Protection of Personal Data and guarantee of digital rights and Regulation (EU) 2016/679 of the European Parliament and of the Council, of April 27 of 2016, regarding the protection of natural persons with regard to the processing of personal data and the free circulation of these data and that Directive 95/46 / CE (General Data Protection Regulation) is repealed.

Can I delete my account?

You can delete your account any time by contacting customer service by email or phone 93 160 00 48.

What is location used for?

We use the location to show you the closest hospitals. If you don’t want to enter it, the location of your mobile device will be used.

Clinical trials

Why are there trials of diverse types of cancer?

It can be due to two cases:

The trial is aimed at more than one type of cancer. For example, there are trials aimed at treating gastric and colorectal tumors, in this case it would be defined as a study for several types.

It is a “basket” type clinical trial directed at a genetic mutation. In this type of trial, the drugs seek to attack a specific mutation and not a specific type of tumor. Therefore, people who have different tumors with the same mutation can apply.

Is there any cost to participate in a clinical trial?

Participants are not charged for the treatment received during the clinical trial. However, depending on the trial sponsor, you may or may not be reimbursed for travel and accommodations expenses incurred. All this information will be provided before starting the study.

Who sponsors clinical trials?

We need to compare your diagnosis data with the inclusion and exclusion criteria of the more than 800 clinical trials in our database. Therefore, the application will take a few minutes to show you the result. You will receive a notification when the search process is complete and we have found the trials related to your diagnosis.

It is safe to participate in a clinical trial?

Trial protocols must be approved by the AEMPS (Spanish Agency of Medicines and Medical Products) and drug research ethics committees, which ensure patient safety. Patients’ rights, safety and wellbeing are always the top priority and your data will be completely confidential.


I cannot introduce a query

It can be due to not having the email verified. Check your inbox, and the Spam in case the verification email arrived there. If the problem persists, contact our team.

I have problems using the app

We recommend to have the latest version of the app installed. In that case, if the problem persist contact our team.

What does “Not yet recruiting” mean?

It means that this clinical trial or hospital has not started recruiting patients. You can request to be notified once the recruitment is initiated.

I forgot my password

You can get a reminder of your username and password on the Profile page of the app, editing your profile. If you have any problems, contact our team.


What is a clinical trial?

A clinical trial is the basis for developing a new drug that can later be commercialised or administered to patients diagnosed with that disease in the future. To do so, a study is conducted with volunteers who help scientists discover new therapies and play an active part in scientific research.

Clinical trials can last several years and have various phases.

What are inclusion and exclusion criteria of clinical trials?

Inclusion criteria are the factors a patient must have to qualify for the trial. For example, inclusion criteria can include sex, age, having a certain disease or specific test results.

Exclusion criteria are the factors that disqualify a patient from participating in the study. For example, depending on the trial requirements, exclusion criteria can include sex, age, type or phase of the disease and having or not having other diseases.

What is screening?

Screening is a series of tests done before starting the study to make sure patients meet all the established inclusion criteria and none of the exclusion criteria. If you meet all the criteria, the process will continue.

What is a placebo?

A placebo is a substance without any pharmacological effect that is used as a control to compare the molecule being studied against. Not all clinical trials use them and they are rare in cancer trials. However, in other types of clinical trials they can be used to prove the efficacy of the treatment studied.

What are the lymph nodes?

The lymph nodes are responsible for transporting lymph, a fluid that contains lymphocytes, responsible for the immune response. They are distributed throughout the body, although they abound in specific areas such as the armpits, groin, neck and abdomen. When the tumor begins to spread, it often affects nearby lymph nodes, known as lymph node involvement.

What is a comorbidity?

Comorbidities are one or more additional conditions a person may have that could interfere with the disease the study focuses on, in this case cancer.

What is a mutation?

A mutation is an alteration in the DNA sequence that normally occurs spontaneously. However, it can also be induced by mutagenic factors such as radiation, some chemical substances or viruses. In most cases, mutations are neutral, so they have no effect on the individual survival or reproduction. In other cases, mutations can cause changes in genes that alter the normal functioning of the body, leading to diseases such as cancer.
