Pricing and reimbursement of orphan drugs: the need for more transparency

Steven Simoens
Orphanet Journal of Rare Diseases 2011, 6:42doi:10.1186/1750-1172-6-42
Published: 17 June 2011

OPEN ACCES

Abstract (provisional)

Pricing and reimbursement of orphan drugs are an issue of high priority for policy makers, legislators, health care professionals, industry leaders, academics and patients. This study aims to conduct a literature review to provide insight into the drivers of orphan drug pricing and reimbursement. Although orphan drug pricing follows the same economic logic as drug pricing in general, the monopolistic power of orphan drugs results in high prices: a) orphan drugs benefit from a period of marketing exclusivity; b) few alternative health technologies are available; c) third-party payers and patients have limited negotiating power; d) manufacturers attempt to maximise orphan drug prices within the constraints of domestic pricing and reimbursement policies; and e) substantial R&D costs need to be recouped from a small number of patients. Although these conditions apply to some orphan drugs, they do not apply to all orphan drugs. Indeed, the small number of patients treated with an orphan drug and the limited economic viability of orphan drugs can be questioned in a number of cases. Additionally, manufacturers have an incentive to game the system by artificially creating monopolistic market conditions. Given their high price for an often modest effectiveness, orphan drugs are unlikely to provide value for money. However, additional criteria are used to inform reimbursement decisions in some countries. These criteria may include: the seriousness of the disease; the availability of other therapies to treat the disease; and the cost to the patient if the medicine is not reimbursed. Therefore, the maximum cost per unit of outcome that a health care payer is willing to pay for a drug could be set higher for orphan drugs to which society attaches a high social value. There is a need for a transparent and evidence-based approach towards orphan drug pricing and reimbursement. Such an approach should be targeted at demonstrating the relative effectiveness, cost-effectiveness and economic viability of orphan drugs with a view to informing pricing and reimbursement decisions.

Repligen Reports Fourth Quarter ........ "RG2833 for Friedreich’s Ataxia"

9th of June 2011

RG2833 for Friedreich’s Ataxia
We are currently developing histone deacetylase class 1 inhibitors for the treatment of inherited neurodegenerative diseases such as Friedreich's ataxia. Friedreich's ataxia is caused by inadequate production of the protein frataxin which leads to degeneration of the nerves controlling muscle movements. Pending regulatory approval, we plan to initiate a Phase 1 study of RG2833 in Friedreich's ataxia patients in Europe by the end of the year. We are currently engaged in discussions with potential
pharmaceutical partners to evaluate whether partnering this program would increase the trajectory for global development and ultimately maximize the commercial potential of the asset.

Differential Expression of PGC-1α and Metabolic Sensors Suggest Age-Dependent Induction of Mitochondrial Biogenesis in Friedreich Ataxia Fibroblasts

2011 PLoS ONE 6(6): e20666. doi:10.1371/journal.pone.0020666, OPEN ACCESS

García-Giménez JL, Gimeno A, Gonzalez-Cabo P, Dasí F, Bolinches-Amorós A, et al.

The induction of mitochondrial biogenesis in FRDA may be a consequence of the mitochondrial impairment associated with disease evolution. The increase of ROS and the involvement of the oxidative phosphorylation may be an early event in the cell pathophysiology of frataxin deficiency, whereas increase of mitochondriogenic response might be a later phenomenon associated to the individual age and natural history of the disease, being more evident as the patient age increases and disease evolves. This is a possible explanation of heart disease in FRDA.

Clinical trials for stem cell therapies

OPEN ACCESS

In recent years, clinical trials with stem cells have taken the emerging field in many new directions. While numerous teams continue to refine and expand the role of bone marrow and cord blood stem cells for their vanguard uses in blood and immune disorders, many others are looking to expand the uses of the various types of stem cells found in bone marrow and cord blood, in particular mesenchymal stem cells, to uses beyond those that could be corrected by replacing cells in their own lineage. Early results from these trials have produced mixed results often showing minor or transitory improvements that may be attributed to extracellular factors. More research teams are accelerating the use of other types of adult stem cells, in particular neural stem cells for diseases where beneficial outcome could result from either in-lineage cell replacement or extracellular factors. At the same time, the first three trials using cells derived from pluripotent cells have begun.
