Budget impact model in moderate-to-severe psoriasis vulgaris assessing effects of calcipotriene and betamethasone dipropionate foam on per-patient standard of care costs

Aims: To develop a budget impact model (BIM) for estimating the financial impact of formulary adoption and uptake of calcipotriene and betamethasone dipropionate (C/BD) foam (0.005%/0.064%) on the costs of biologics for treating moderate-to-severe psoriasis vulgaris in a hypothetical US healthcare plan with 1 million members.

Methods: This BIM incorporated epidemiologic data, market uptake assumptions, and drug utilization costs, simulating the treatment mix for patients who are candidates for biologics before (Scenario #1) and after (Scenario #2) the introduction of C/BD foam. Predicted outcomes were expressed in terms of the annual cost of treatment (COT) and the COT per member per month (PMPM).

Results: At year 1, C/BD foam had the lowest per-patient cost ($9,913) necessary to achieve a Psoriasis Area and Severity Index (PASI)-75 response compared with etanercept ($73,773), adalimumab ($92,871), infliximab ($34,048), ustekinumab ($83,975), secukinumab ($113,858), apremilast ($47,960), and ixekizumab ($62,707). Following addition of C/BD foam to the formulary, the annual COT for moderate-to-severe psoriasis would decrease by $36,112,572 (17.91%, from $201,621,219 to $165,508,647). The COT PMPM is expected to decrease by $3.00 (17.86%, from $16.80 to $13.80).

Limitations: Drug costs were based on Medi-Span reference pricing (January 21, 2016); differences in treatment costs for drug administration, laboratory monitoring, or adverse events were not accounted for. Potentially confounding were the definition of “moderate-to-severe” and the heterogeneous efficacy data. The per-patient cost for PASI-75 response at year 1 was estimated from short-term efficacy data for C/BD foam and apremilast only.

Conclusions: The introduction of C/BD foam is expected to decrease the annual COT for moderate-to-severe psoriasis treatable with biologics by $36,112,572 for a hypothetical US healthcare plan with 1 million plan members, and to lower the COT PMPM by $3.00.

中国电解铝行业市场支配力变迁的实证研究——基于2002—2009年的数据

选取2002—2009年中国电解铝行业的月度数据,以Baker和McGahan的NEIO模型为基础,利用未预期的负冲击是否会导致卡特尔厂商对竞争对手的欺诈行为而打价格战的模型,检验2002—2009年期间串谋等卡特尔行为是否存在。实证结果表明:2006—2009年期间中国电解铝行业存在明显的市场支配力,而不能确定2002—2005年市场支配力是否存在;2006—2009期间的平均市场支配力比2002—2005年高出0.3。提出行业本身属性、政府政策的引导、大企业保持额外产能是导致这种差距的三个主要原因。     

含硼聚硅铝的形貌结构研究

向聚硅酸中引入Al3+、B,制得稳定性更好的高效絮凝剂含硼聚硅铝(PASB)。用电子显微镜观察分析了PASB的形貌,用红外光谱和X-射线研究了其中B、铝离子及其水解产物与聚硅酸的相互作用情况,并对其电学特征进行了考察。结果表明B、铝离子及其水解产物和聚硅酸等多种组分之间有相互作用,形成了尺度更大的聚集单元。PASB的这种特殊结构是其具有良好稳定性和混凝性能的根本原因。
