Objective: The objectives of this review are to identify barriers/facilitators to designing, maintaining, and utilizing rare disease patient registries (RDPRs); determine whether and how these differ among patient partners, other knowledge users (KUs), and researchers; and chart definitions of rare diseases and RDPRs.

Introduction: RDPRs are vital to improving the understanding of the natural histories and predictors of outcomes for rare diseases, assessing interventions, and identifying potential participants for clinical trials. Currently, however, the functionality of RDPRs is not fully optimized.

Background: Precision medicine (PM) is a form of personalized medicine that recognizes that individuals with the same condition may have different underlying factors and uses molecular information to provide tailored treatments. This approach can improve treatment outcomes and transform lives through favorable risk/benefit ratios, avoidance of ineffective interventions, and possible cost savings, as evidenced in the field of lung cancer and other oncology/therapeutic settings, including cardiac disease, diabetes, and rare diseases. However, the potential benefits of PM have yet to be fully realized.

Background And Objective: Rare diseases place a significant burden on patients, families, the healthcare system, and society. Evidence on the socioeconomic burden of rare disease is limited and mostly reflects diseases where treatments are available. We developed a framework encompassing recommended cost elements for studies of the socioeconomic burden of rare diseases.

Background: Treatments are often unavailable for rare disease patients, especially in low-and-middle-income countries. Reasons for this include lack of financial support for therapies and onerous regulatory requirements for approval of drugs. Other barriers include lack of reimbursement, administrative infrastructure, and knowledge about diagnosis and drug treatment options.

Article Synopsis
  • European health authorities are increasingly worried about rising prices for new cancer medications that aren't necessarily improving health outcomes, impacting healthcare system sustainability.
  • There's a discussion among payers and advisers about various pricing strategies for these new treatments, including effectiveness levels and different pricing models.
  • As new cancer drugs and therapies emerge, coupled with high prices and complex discounting, there will likely be more scrutiny and demand for transparency in pricing, especially as patents on existing medicines expire.

Background: Rare Disease research has seen tremendous advancements over the last decades, with the development of new technologies, various global collaborative efforts and improved data sharing. To maximize the impact of and to further build on these developments, there is a need for model consent clauses for rare diseases research, in order to improve data interoperability, to meet the informational needs of participants, and to ensure proper ethical and legal use of data sources and participants' overall protection.

Methods: A global Task Force was set up to develop model consent clauses specific to rare diseases research, that are comprehensive, harmonized, readily accessible, and internationally applicable, facilitating the recruitment and consent of rare disease research participants around the world.

Familial hypercholesterolaemia (FH) is an autosomal-dominant disorder associated with high low-density lipoprotein cholesterol (LDL-C). Left untreated, 50% of men with FH will develop coronary heart disease by the age of 50 and 30% of women by the age 60 [1,2]. It is estimated that the prevalence may be as high as one in 250 people, with most undiagnosed.

Rare diseases collectively exert a global public health burden in the severity of their manifestations and the total number of people they afflict. For many patients, considerable barriers exist in terms of access to appropriate care, delayed diagnosis and limited or non-existing treatment options. Motivated by these challenges, the rare disease patient community has played a critical role, elevating the patient voice and mobilizing legislation to support the development of programs that address the needs of patients with rare diseases.

Real-life experiences of grassroots patient organizations across a variety of diseases, countries and contexts have been used to develop a four-mode framework of the transition from patient advocacy to partnership, defined by one axis as individual versus collective action and the other axis as activities 'outside' or 'inside' the system. The four quadrants are labeled as advocacy, activism, reform and broker, and engagement is further refined by whether the participation is 'pushed' by the group or 'pulled' by the system. There are many examples of patient advocacy groups transitioning through the four quadrants; however, depending on other factors of culture, opportunity and their own preferences, groups may work primarily through one or two quadrants.

Objectives: A patient reported outcome (PRO) is "any report of the status of a patient's health condition that comes directly from the patient without interpretation of the patient's response by a clinician or anyone else" (USFDA 2009). PROs are discussed widely, and many regard the patients' perspective on treatment benefit as very valuable. Although many PROs have shown satisfactory measurement properties including reliability, validity, and responsiveness, there is great concern about risk of bias, that is, in clinical trials.

Introduction: Policy decisions related to orphan and ultra-orphan drugs challenge traditional decision-making processes and often frustrate those affected by them. In general, these drugs are associated with significant uncertainties around clinical benefit, 'value for money', affordability, and 'adoption/diffusion', all of which arise from a lack of available high-quality evidence. Increasingly, patients with rare diseases and their families are looking for opportunities to contribute to initiatives aimed at reducing these uncertainties.

Objectives: Rare diseases are often heterogeneous in their progression and response to treatment, with only a small population for study. This provides challenges for evidence generation to support HTA, so novel research methods are required.

Methods: Discussion with an expert panel was augmented with references and case studies to explore robust approaches for HTA evidence generation for rare disease treatments.

This article is a call for action to the relevant stakeholders to improve access to care and treatment for patients with rare diseases in the Asia-Pacific region by looking into three main areas: (a) developing legislative definitions to confer enforceable protection, (b) creating or strengthening policies by objectively measuring the impact brought about by rare diseases and establishing platforms to reach out to the rare disease community, and (c) fostering collaboration across sectors and countries. It is hoped that these suggested actions can catalyze discussions and progress in the region.

Quality indicators are increasingly used as a tool to achieve safe and quality clinical care, cost-effective therapy, for professional learning, remuneration, accreditation and financial incentives. A substantial number focus on drug therapy but few address the introduction of new medicines even though this is a burning issue. The objective was to describe the issues and challenges in designing and implementing a transparent indicator framework and evaluation protocol for the introduction of new medicines and to provide guidance on how to apply quality indicators in the managed entry of new medicines.
