Most frequently asked questions

  • Is there a medicine for my disease?

    A list of the latest marketing authorisations and orphan medicinal product designations is available here.

    You can also view the list of the Community Register of Orphan Medicinal Products.

    In addition to orphan medicines (i.e. authorised medicines with an orphan status), some medicines are authorised at the EU level with an indication for a rare disease but without an orphan status. For more information, please consult the Orphanet Report Series. In addition, some medicines (without an orphan status) are used to treat rare disease patients and are authorised at the national level.

    For more information on what treatments are available in your country please contact your national competent authority.

  • Is there research into, or an ongoing clinical trial for, my rare disease?

    You can search or Orphanet. If you have any questions on how to search for a clinical trial contact us.

  • I know there is a medicine for my disease, but what can I do if I cannot get it?

    Have you encountered challenges accessing treatment for your condition, such as medicines, medical devices, surgeries, or consultations? The EURORDIS Access Campaign Questionnaire invites people living with a rare disease who have faced difficulties accessing treatment to participate in a brief online survey.

    When confronted with difficulties obtaining necessary medicines, it’s crucial to address various aspects of access, including affordability, availability, and geographical considerations. 

    If the medicine is too expensive, explore options like patient assistance programmes. Additionally, contact your health insurance provider to check if the medicine is covered.

    For EU citizens seeking medicines available in another EU country, you have the right to access healthcare and be reimbursed for care abroad. The conditions for this are outlined in the Directive 2011/24/EU on patients’ rights in cross-border healthcare and Regulation (EC) No 883/2004. While the directive is not fully applied by all Member States, EURORDIS advocates for its comprehensive implementation. Contact your national contact point for more information on accessing cross-border healthcare.

  • What can, and cannot, EURORDIS do to help me with my situation?

    EURORDIS cannot respond to questions concerning the medical aspects of a rare disease. EURORDIS does not employ qualified medical personnel or information specialists to give medical advice, diagnose illness, or offer referrals. We strongly recommend that you seek the advice of your health care provider with questions regarding medical care. If you need help finding a patient group for your disease please search here or search for an expert centre or network (Orphanet).

    However, EURORDIS is collaborating with the European Medicines Agency to involve patients in the Protocol Assistance procedures. Protocol assistance is a form of scientific advice for orphan medicines. Please contact us for more information.

  • Can patients get involved in medicines' development?

    Patient engagement in rare disease treatment development is crucial for ensuring that medicines effectively address real-life needs. EURORDIS facilitates patient representatives’ participation in various committees, e.g. COMP, at the European Medicines Agency (EMA), allowing them to contribute throughout the life cycle of orphan medicines. Patients can serve as full members or ad-hoc experts in these committees.

    EURORDIS also coordinates internal working groups, such as the Therapeutic Action Group (TAG) and the Drug Information, Transparency, and Access (DITA) Task Force. TAG comprises EURORDIS volunteers in EMA scientific committees, while DITA focuses on product information, regulatory process transparency, and access to medicines.

    If you are a patient representative or a researcher looking to gain knowledge and become an expert on the R&D of medicines for rare diseases you can also take part in the EURORDIS School on Medicines Research & Development.

Safety of orphan medicines

About medicines for rare diseases

  • What is an orphan medicine?

    Orphan medicines are intended for the diagnosis, prevention or treatment of rare diseases.

    These medicines were called “orphan” because under normal market conditions (i.e. in the absence of an orphan regulation) the pharmaceutical industry has little interest in developing and marketing products intended for only a small number of patients, when the high cost of bringing a medicinal product to market may not be recovered by the expected sales of the product.

    The EU Orphan Medicinal Products Regulation (2000) brought into place a range of incentives aimed at encouraging the development of medicines for rare diseases. Since 1999 there have been over 2000 orphan designations and around 200 orphan medicines authorised for market. Orphan medicines may also be paediatric medicines for the treatment of rare diseases in children, or advanced therapies.

  • What is an advanced therapy?

    Advanced therapy medicinal products (ATMPs) are medicines for human use that are based on genes, tissues or cells. They are highly relevant for the treatment of rare diseases as they might, for example, target the genetic cause of a rare disease. Research to develop ATMPs for rare diseases creates a pool of knowledge that can be highly valuable for the development of medicinal products for more common diseases.

  • What other forms of treatment are available for a person living with a rare disease?

    Medical devices, surgery, radiotherapy, physiotherapy, assistive technologies and digital devices may also be used in the treatment of rare diseases.

  • What is a repurposed medicine?

    A repurposed medicine is a medicine already approved for human use in a certain indication and for which researchers or clinicians identify new disease(s) that the medicine could treat (i.e. a new indication). Because the medicine is already in use, some data are already available, especially regarding the safety profile of the medicine. Additional data have to be collected through clinical study to confirm the efficacy of a medicine in the new patient population. However, the repurposing approach brings advantages for a rare disease as it saves money and time as a new compound doesn’t have to be found and developed from scratch.

The development & authorisation of orphan medicines

  • How are orphan medicines authorised for the Europe?

    The sponsor (public or private) developing an orphan medicine can apply to the European Medicines Agency (EMA) for orphan designation. After full review, the EMA’s Committee for Orphan Medicinal Products (COMP) issues an opinion recommending whether the orphan designation should be granted and the European Commission makes the final decision.

    Once designation is granted, and the development has progressed, the sponsor must submit an application for marketing authorisation to the EMA for assessment through the centralised procedure. The benefit-risk ratio of the medicine (i.e. the balance between the efficacy and the safety of the medicine) is assessed by EMA’s Committee for Medicinal Products for Human Use (CHMP). The EMA’s CHMP makes a recommendation on whether or not a medicine should be authorised for use in humans (i.e. whether a market authorisation should be granted). Of note: Designated orphan medicines are eligible for conditional marketing authorisation.

    In parallel, the COMP is reviewing the criteria for orphan designation in order to assess whether the orphan status still holds. Then the European Commission takes the final decision on whether to authorise the medicine based on that recommendation and whether to maintain this orphan status or not.

    You can also see the EMA’s interactive tool setting out the development and authorisation of medicines for human use.

    Once a medicine is authorised at the EU level, the process moves to the national level.

    The national competent authorities for pricing and reimbursement decide whether the medicine can be provided and how. In many cases, a health technology assessment body assesses whether the medicine is effective/ cost effective in comparison to existing medicines available in that country and provides a recommendation on whether that medicine should be reimbursed by the national healthcare system – this process is called health technology assessment. The ultimate goal is to have authorised medicines available, affordable and accessible for rare disease patients.

  • How are patients involved in the evaluation of a marketing authorisation?

    In the EU, patients are involved in benefit-risk discussions at the EMA as members of the Pharmacovigilance Committee (PRAC), through their participation in scientific advice/protocol assistance procedures, and in Scientific Advisory Group (SAG) meetings. There is also a pilot initiative involving patients in the CHMP during oral explanations preceding decision-making.

    EMA: The evaluation of medicines, step-by-step

  • What is EURORDIS' role in the development of medicines?


    • Advocates for the development of and improved access to innovative orphan medicines that are meaningful to rare disease patients.
    • Engages patients in the development process all along the life-cycle of orphan medicines and develops tools to facilitate the engagement of patients in this process. For example, we facilitate the participation of patient representatives in committees and working parties at the EMA so the patient voice is part of the debate, advice to clinical developments and assessment of applications for orphan designation and authorisations.
    • Empowers patient representatives with the knowledge and skills needed so they are positioned as experts when sitting at the same table as companies, researchers and regulators.

    Read more about our advocacy actions in the area of treatments.

  • What is a clinical trial?

    Any investigation in human subjects intended to discover or verify the clinical, pharmacological and/or other pharmacodynamic effects of an investigational product(s), and/or to identify any adverse reactions to an investigational product(s), and/or to study absorption, distribution, metabolism, and excretion of an investigational product(s) with the object of ascertaining its safety and/or efficacy. The terms “clinical trial” and “clinical study” are synonymous.

Access to orphan medicines

  • How can I find a list of orphan medicines that have been authorised at the EU level?

    A list of the latest marketing authorisations and orphan medicinal products designations is available here.

    You can also view the list of Community Register of orphan medicinal products.

    In addition to orphan medicines (i.e. authorized medicines with an orphan status), some medicines are authorised at EU level with an indication for a rare disease but without an orphan status. For more information, please consult the Orphanet Report Series. In addition, some medicines (without an orphan status) are used to treat rare diseases patients and are authorised at the national level.

  • How can I find out a medicine for my disease is available in my country?

    For more information on what treatments are available in your country please contact your national competent authority.

  • An orphan medicine has been authorised at the EU level but isn’t available in my country, why?

    Once a medicine is authorised at the EU level, the next step is for the national authorities to negotiate a price for the medicine and decide if it will be reimbursed through the national healthcare system. Unfortunately this decision is not always immediately positive. They may decide the price is too high, negotiations with the company may break down, or they may assess that the effectiveness of the medicine and added value in comparison to an existing medicine available in that country is not high enough.

  • What is off-label use of a medicine?

    When doctors prescribe a medicine for a use different from what is authorised on the label, this is called “off label” use. For example when the drug is prescribed for a different disease or when the dosage differs from the one stated on the label. Patients with rare diseases and their families are often familiar with this practice, or may not even realise that they are taking products that are prescribed “off-label”.

  • Can I access a medicine in another country through cross-border healthcare? How?

    EU citizens have the right to access healthcare in any EU country and to be reimbursed for care abroad by their home country.

    The conditions under which a patient may travel to another EU country to receive medical care and reimbursement are set out in the Directive 2011/24/EU on patients’ rights in cross-border healthcare and Regulation (EC) No 883/2004 of the European Parliament and of the Council of 29 April 2004 on the coordination of social security systems.

    The Directive covers healthcare costs, as well as the prescription and delivery of medications and medical devices.

    However, the Directive is not yet fully applied by Member States and the process to access the right to cross border care may not results in a suitable outcome.

    EURORDIS is advocating for the fulfilment of European patients’ rights under this Directive through its full implementation in every country. Contact your national contact point to find out more about how to access cross-border healthcare.

  • How can I access an unauthorised medicine through a compassionate use programme?

    A compassionate use programme (CUP) consists of making a medicinal product available for compassionate reasons to a group of patients (or sometimes individual patients on a case-by-case basis) with a chronically or seriously debilitating disease or whose disease is considered to be life-threatening, and who cannot be treated satisfactorily by an authorised medicinal product. Learn more about compassionate use.

  • Are there other mechanisms in place to bring rare disease medicines to patients more quickly?

    The European Medicines Agency has put in place mechanisms including the PRIME scheme. This voluntary scheme is based on enhanced interaction and early dialogue with developers of promising medicines, to optimise development plans and speed up evaluation so these medicines can reach patients earlier.

    The European Commission has also proposed a Regulation to make European cooperation on health technology assessment permanent, stable and sustainable. Pooling expertise together aims to support the decision-making on added value, pricing and reimbursement of health technologies across European countries, both for those who already have high capacity in assessing the value of new technologies and for those who have none.

    EURORDIS strongly advocated for the approval of this HTA regulation during these last years and for the implementation of the consequent cooperation.

  • What is EURORDIS doing to improve patients’ access to rare disease treatments?

    EURORDIS has put forward a proposal to tackle the challenges that prevent patients’ access to care and medicines, including the ambition to have 3 to 5 times more new rare disease therapies approved per year by 2025, 3 to 5 times cheaper than today.

  • What is health technology assessment (HTA)?

    HTA  is a multi-disciplinary field and a process performed by competent authorities or sometimes academics to inform health policies. It consists of examining the long-term effects of any existing or new health care technology, including drugs, medical devices, procedures and organisational systems used in health care.

    HTA plays an important role in determining pricing negotiations, reimbursement decisions, and the organisation of the health systems (including for orphan medicinal products and rare diseases).

    HTA also evaluates the medical, social, ethical and economic implications of these interventions. The goal of HTA is to support health care decisions and to serve policy making through objective information.

    HTA is mainly performed at national level to inform governments’ policies. Since 1988 European Countries have tried to cooperate on HTA to make it more evidence-based, timely and transparent. The European Commission has been funding several projects of voluntary cooperation among national competent authorities for HTA (for example, the European Network for HTA – EUnetHTA). Today, the European Commission has proposed a Regulation to make European cooperation on HTA permanent and beneficial for all EU countries.
