BACKGROUND: After the inclusion of more high-cost orphan drugs in China\'s National Reimbursement Drugs List, this study investigated issues relating to patient access to the 7 medicines for 4 rare diseases after listing.
METHODS: This study collected data from a national survey conducted in China. Three aspects associated with the accessibility of medicines, namely, approachability, availability, and affordability, were analyzed using descriptive statistics. In addition, multilevel logistic regression models were used to investigate the associations between patient characteristics and the accessibility of surveyed orphan drugs.
RESULTS: Of the 999 completed responses included in the study, 15% of the patients (n = 150) did not use the medicines because of non-medicine-related issues. Among the 849 patients using the surveyed medications, 64.4% (n = 547) encountered the problem of unavailability, whereas 51.2% (n = 435) reported affordability as an issue, and 49.6% (n = 320) had health expenditure beyond the catastrophic threshold. The data also indicated that Commercial Medical Insurance helped patients to relieve the cost burden on orphan drugs, but the payout of Commercial Medical Insurance failed to influence patients\' decisions to continue the treatments.
CONCLUSIONS: Accessibility of orphan drugs has improved in China after their inclusion in the National Reimbursement Drugs List. Nevertheless, the availability and affordability of medicines remained the barriers for patients to access the desired treatments. It is recommended that further policy refinement in conjunction with the collaboration among healthcare stakeholders is required to deliver better care for patients with rare disease.

This last decade has been marked by significant advances in the development of cell and gene (C&G) therapies, such as gene targeting or stem cell-based therapies. C&G therapies offer transformative benefits to patients but present a challenge to current health technology decision-making systems because they are typically reviewed when clinical efficacy data are very limited and when there is uncertainty about the long-term durability of outcomes. These challenges are not unique to C&G therapies, but they face more of these barriers, reflecting the need for adapting existing value assessment frameworks. Still, C&G therapies have the potential to be cost-effective even at very high price points. The impact on healthcare budgets will depend on the success rate of pipeline assets and on the extent to which C&G therapies will expand to wider pathologies beyond rare or ultra-rare diseases. Getting pricing and reimbursement models right is important for incentivising research and development investment while not jeopardising the sustainability of healthcare systems. Payers and manufacturers therefore need to acknowledge each other\'s constraints-limitations in the evidence generation on the manufacturer side, budget considerations on the payer side-and embrace innovative thinking and approaches to ensure timely delivery of therapies to patients. Several experts in health technology assessment and clinical experts have worked together to produce this publication and identify methodological and policy options to improve the assessment of C&G therapies, and make it happen better, faster and sustainably in the coming years.
