World health dilemmas: Orphan and rare diseases, orphan drugs and orphan patients.

ABSTRACT: According to global annual estimates hunger/malnutrition is the major cause of death (36 of 62 million). Cardiovascular diseases and cancer (5.44 of 13.43 million) are the major causes of death in developed countries, while lower respiratory tract infections, human immunodeficiency virus infection/acquired immunodeficiency syndrome, diarrhoeal disease, malaria and tuberculosis (10.88 of 27.12 million) are the major causes of death in developing countries with more than 70% of deaths occurring in children. The majority of approximately 800 million people with other rare diseases, including 100000 children born with thalassaemia annually receive no treatment. There are major ethical dilemmas in dealing with global health issues such as poverty and the treatment of orphan and rare diseases. Of approximately 50000 drugs about 10% are orphan drugs, with annual sales of the latter approaching 100 billion USD. In comparison, the annual revenue in 2009 from the top 12 pharmaceutical companies in Western countries was 445 billion USD and the top drug, atorvastatin, reached 100 billion USD. In the same year, the total government expenditure for health in the developing countries was 410 billion USD with only 6%-7% having been received as aid from developed countries. Drugs cost the National Health Service in the United Kingdom more than 20 billion USD or 10% of the annual health budget. Uncontrollable drug prices and marketing policies affect global health budgets, clinical practice, patient safety and survival. Fines of 5.3 billion USD were imposed on two pharmaceutical companies in the United States, the regulatory authority in France was replaced and clinicians were charged with bribery in order to overcome recent illegal practises affecting patient care. High expenditure for drug development is mainly related to marketing costs. However, only 2 million USD was spent developing the drug deferiprone (L1) for thalassaemia up to the stage of multicentre clinical trials. The criteria for drug development, price levels and use needs to be readdressed to improve drug safety and minimise costs. New global health policies based on cheaper drugs can help the treatment of many categories of orphan and rare diseases and millions of orphan patients in developing and developed countries.

Project description:BackgroundOver the past 30 years, the healthcare industry has increasingly turned its attention to rare diseases. Regulators have emphasized the need for clinical research in this area to be patient-centered. However, there is a lack of evidence concerning whether this need is actually met. In this paper, we aim to address this gap.MethodsFirst, we describe the state of patient-centricity in clinical research in rare diseases based on a targeted literature review. Second, we discuss recommendations from scientific bodies on patient-reported outcome (PRO) measures in rare diseases. Third, we analyze data collected from EMA's and FDA's websites concerning rare disease labeling claims and data from Clinicaltrials.gov concerning the use of PRO measures in rare disease pivotal trials. Fourth, we perform an exhaustive literature review on the use of PRO measures in the pharmaceutical industry, including all phases of clinical research, observational/registry studies, and instrument development and validation.ResultsThere is limited information on rare disease patient engagement in study design, recruitment, and retention. None of the initiatives describing methods for developing PRO measures in rare diseases provide the clear guidance clinical researchers need. Only 17.4% of orphan drug labels contain a PRO measure. Less than half of pivotal trials in orphan drugs have a PRO measure as a primary or a secondary endpoint. Although the number of publications about PRO measures in rare diseases has risen in the past fifteen years, our results indicate that substantial improvements are needed to achieve patient-centricity.ConclusionsThe nature and extent of patient engagement in rare disease research is under-documented. The current paradigm for developing and using PRO measures in clinical research is failing to meet the needs of rare disease patients. Not only are PROs rarely used as high-level endpoints in clinical trials or taken into account in labeling claims, they are also under-researched overall - there are too few measures for the multitude of rare diseases. We call for a clear guidance on patient engagement and suggest a realistic approach to the adaptation of PRO strategy to the specific context of clinical research in rare diseases.

Project description:Background: Despite calls for the use of real-world data, the rare diseases (RD) treatment landscape suffers from a scarcity of data referred to orphan medicinal products (OMP) use at the population level. Objectives: We aim to describe the characteristics and patterns of utilization of OMP in a sizable group of RD patients globally monitored by an area-based rare diseases registry located in the Veneto region, Italy, during a 3-year period (1 January 2019 to 31 December 2021). Methods: A list of OMP (n = 60) was assembled for study purposes, according to extensive criteria with regard to the status of orphan designation and of national reimbursement decisions. Results: OMP prescriptions involved 1,010 patients, corresponding to the 2.3% of all the patients monitored by the RD registry. Nearly one out of five (22.8%) was a pediatric patient at the time of the first prescription. OMP use interested a limited proportion (17.5%) of diseases approaching the rarity threshold, having a prevalence of less than five per 10,000, while individuals affected by these more common rare conditions represented 49% of all the patients receiving an OMP prescription. A clustering effect of OMP use was observed in selected groups of diseases, mainly, neurological, hematological, and hereditary metabolic ones. Medication plans including an OMP show in the 45.9% of the cases a high level of complexity, both in terms of nature and number of co-prescribed treatments. Off-label use interested 15.3% (n = 155) of all the RD patients with at least an OMP prescription during the study period. Conclusion: Data collected in a real-world setting through population-based registries globally monitoring RD patients, including related medication plans, have the potential to identify which diseases, and thus patients, have less benefit from the advent of OMP so far. Furthermore, in the rapidly evolving RD therapeutic landscape, they can help understand which therapeutic areas are most in need of investment to address existing unmet care needs.
