TO THE EDITOR:

The Hospital Exemption rule is considered a valuable European legislative initiative that guarantees patient access to novel therapies based on the use of advanced therapy medicinal products (ATMPs) in the Member States. On the occasion of the update of the European General Pharmaceutical Legislation, the Spanish Network of Advanced Therapies (TERAV, formerly TerCel), which has played a recognized leadership in Europe in the development of both academic and pharmaceutically commercialized ATMPs [1], would like to make the following position statement:

The Hospital Exemption Clause was established in the European ATMP regulation EC1394/2007 (Article 28) [2], to enable manufacturing of ATMPs outside the standard centralized marketing authorization common pathway, with the following conditions: “ATMP is prepared on a non-routine basis according to specific quality standards, and used within the same Member State in a hospital under the exclusive professional responsibility of a medical practitioner, in order to comply with an individual medical prescription for a custom-made product for an individual patient” and “Manufacturing of these products shall be authorized by the competent authority of the Member State. Member States shall ensure that national traceability and pharmacovigilance requirements as well as the specific quality standards at Community level in respect of advanced therapy medicinal products for which authorization is required pursuant to Regulation”.

It is relevant to stress that products administered throughout Hospital Exemption are under the oversight of the corresponding national competent authority of each Member State after careful risk-benefit analysis of the medicinal product. This includes for instance, in the “Spanish Model”, a thorough evaluation by the Spanish Agency of Medicines and Medical Devices (AEMPS) of preclinical and clinical data, as well as the inspection and accreditation of the GMP Cell Production Facility and a Pharmacovigilance Plan, among other aspects, which are similar to those required for a centralized marketing authorization, in order to ensure the quality, safety and efficacy of the pharmaceutical product. An unsolved potential problem that the updated regulation should define is the lack of harmonization in the requirements established for Hospital Exemption in the different Member States [3]. On the basis of our very positive experience, we strongly suggest to extend this Spanish Model to those systems where preclinical and clinical data or other more stringent criteria are not evaluated for product approval.

In this setting, is important to note that we strongly support the establishment of a public EU registry of the uses and characteristics of ATMPs available through Hospital Exemption. In addition, patients treated with ATMP through Hospital Exemption should be followed up in registries collecting health outcomes, such as those recommended by the EMA and lead by EU based scientific societies. This would be essential for ensuring not only transparency on the safety and availability of these products, but also to generate scientific knowledge and increase the efficiency of the Health Systems and the awareness of all the stakeholders interested, including academia, pharmaceutical industry, regulators, and especially patients’ associations.

As expected, the number of ATMPs approved by Hospital Exemption is very limited in the EU, and these products have been mainly developed to provide treatments for patients not included or ineligible for participating in clinical trials or where ATMPs were not considered suitable for commercial development. Hospital Exemption is therefore an essential tool to ensure timely access to safe, effective, and legally regulated treatments for patients with rare diseases or those lacking effective treatments or better therapeutic alternatives [4]. Therefore, Hospital Exemption is a stimulus to promote innovation in advanced therapies in European academic institutions. As commented before, the most positive consequence is the increased access of advanced therapies to our patients. The main reasons for this are, amongst others, the fact that they may cover indications not yet approved for commercial CARTs and other ATMPs, the expedited manufacturing time (and at a lower cost) of an academic product, and that they may provide treatment for diseases where pharmaceutical companies are not focused on. Besides, Hospital Exemption clause alleviates the worrying difficulties of supplies to European countries of ATMPs manufactured outside the EU.

Moreover, it is very important to highlight our support of the use of the exemption clause with academic ATMPs also for indications in which there is a commercial product approved, as in the case for instance of CAR-T in hematological malignancies, since many patients do not have access, for a number of reasons, to the approved commercial products. Moreover, these developments may provide important technical and manufacturing improvements that can lead to greater efficacy, lower toxicity or better access. In this regard, we are looking forward to the successes of the EMA pilot program recently launched to help academic and non-profit developers navigate the regulatory processes and optimize development of ATMPs within the EU [5, 6].

In our opinion, the centralized approval and the Hospital Exemption are more complementary than competitive approaches, and Hospital Exemption represents a unique opportunity of partnership between academia and pharmaceutical industry in the benefit of patients, and is one of the most important assets in the European Union to get these highly innovative and disruptive therapies accessible to our national health systems.
