Impact of orphan drugs on Latvian budget.

BACKGROUND: Number of orphan medicinal products on the market and number of rare disease patients, taking these usually expensive products, are increasing. As a result, budget impact of orphan drugs is growing. This factor, along with the cost-effectiveness of orphan drugs, is often considered in the reimbursement decisions, directly affecting accessibility of rare disease therapies. The current study aims to assess the budget impact of orphan drugs in Latvia. METHODS: Our study covered a 5-year period, from 2010 to 2014. Impact of orphan drugs on Latvian budget was estimated from the National Health Service's perspective. It was calculated in absolute values and relative to total pharmaceutical market and total drug reimbursement budget. A literature review was performed for comparison with other European countries. RESULTS: Orphan drug annual expenditure ranged between EUR 2.065 and 3.065 million, with total 5-year expenditure EUR 12.467 million. It constituted, on average, 0.84 % of total pharmaceutical market and 2.14 % of total drug reimbursement budget, respectively. Average annual per patient expenditures varied widely, from EUR 1 534 to EUR 580 952. The most costly treatment was enzyme replacement therapy (Elaprase) for MPS II. Glivec had the highest share (34 %) of the total orphan drug expenditure. Oncological drugs represented more than a half of the total orphan drug expenditure, followed by drugs for metabolic and endocrine conditions and medicines for cardiopulmonary diseases. Three indications: Ph+ CML, MPS II, and PAH accounted for nearly 90 % of the total orphan drug expenditure. CONCLUSIONS: Budget impact of orphan drugs in Latvia is very small. It increased slightly over a period of five years, due to the slight increase in the number of patients and the number of orphan drugs reimbursed. Current Latvian drug reimbursement system is not sufficient for most orphan drugs.

Rare diseases and orphan drugs: Latvian story.

BACKGROUND: Ten years have passed since Latvia became a Member State of the EU in 2004. As a result European regulations, including those related to rare diseases and orphan drugs, have been applied to Latvian legislative system. Orphan diseases have been recognized as a priority area for action in the public health system, though there are significant differences in the national healthcare services for rare diseases among the EU States. This study aims to determine situation in the field of rare diseases in Latvia and compare it with other European countries. METHODS: We used the national plan for rare diseases, EUCERD reports, Orphanet data, Latvian and European regulations, publicly available data from the state agencies, and directly contacted drug manufacturers and wholesalers. RESULTS: National plan for rare diseases was developed and approved in 2013. Although there are no official designated centers of expertise as well as no specific register for rare diseases. Newborns are screened for only two disorders: phenylketonuria and congenital hypothyroidism. Currently 34 orphan drugs are available on Latvian market. Three medicines (8.8%) are included in the reimbursement drug list, all indicated for Ph + CML. 15 drugs (44.1%) were reimbursed within the framework of individual reimbursement system, and five drugs (14.7%) were provided within the program of medicinal treatment of rare diseases in children. CONCLUSIONS: Majority of orphan drugs authorized in the EU are not available in Latvia, moreover those drugs that are available are often not accessible because they are insufficiently reimbursed. Besides, approval of the national plan might be an important step towards improving situation in the field of rare diseases.
