Recombinant factor VIIa (NovoSeven; also known as recombinant activated factor VII or eptacog alfa) is indicated as an intravenous haemostatic agent in haemophilia patients with inhibitors to clotting factors VIII or IX. In noncomparative trials in haemophilia patients with inhibitors, on-demand home treatment with recombinant factor VIIa was effective in controlling episodes of mild to moderate bleeding and well tolerated, with early treatment being associated with a greater rate of success and the need for fewer doses than delayed treatment. Prophylactic treatment with recombinant factor VIIa was also effective in maintaining haemostasis in patients with this indication undergoing surgery. ⋯ In haemophilia patients with inhibitors, recombinant factor VIIa is clinically effective in controlling mild to moderate bleeds, and in maintaining haemostasis in patients undergoing orthopaedic surgery. Available pharmacoeconomic data from several countries, despite inherent limitations, support the use of recombinant factor VIIa as a treatment option that is at least cost neutral relative to aPCC in treating mild to moderate bleeds in this patient population. In addition, orthopaedic surgery with recombinant factor VIIa to maintain haemostasis in haemophilia patients with inhibitors is generally cost saving relative to not having surgery over the medium to long term, as the acquisition costs of recombinant factor VIIa are offset by cost savings resulting from the decrease in the number of joint-related bleeds.

Randomized Controlled Trial
A 1-year prospective cost-effectiveness analysis of roflumilast for the treatment of patients with severe chronic obstructive pulmonary disease.
Roflumilast is an oral, once-daily phosphodiesterase IV (PDE4) inhibitor under investigation for chronic obstructive pulmonary disease (COPD). This study investigated the cost effectiveness of roflumilast in patients with severe to very severe COPD from the perspective of the UK society and UK NHS. ⋯ Roflumilast increased the overall treatment costs of COPD, although the increase was partly offset by reductions in other forms of healthcare use. Roflumilast has the potential to be cost saving in patients with very severe COPD, due to a statistically significant reduction of exacerbations.

Atorvastatin is a lipid-lowering agent that has been evaluated in a number of primary and secondary intervention studies. In the primary prevention trials ASCOT-LLA and CARDS, atorvastatin 10 mg/day significantly reduced cardiovascular events compared with placebo. A prospectively conducted economic analysis of the 3.3-year ASCOT-LLA trial showed that atorvastatin was associated with incremental cost-effectiveness ratios (ICERs) of euro11,693 (UK) and euro12,673 (Sweden) per event avoided (2002 values). ⋯ These modelled analyses have the inherent limitation that projecting long-term outcomes beyond the time period of a clinical trial imparts a degree of uncertainty to the results. Nevertheless, while some findings were sensitive to changes in model assumptions, such as the long-term benefits of statin therapy, most sensitivity analyses showed that results of the base-case analyses were robust to plausible changes in key parameters. Although a clear pattern is not evident from available data, intuitively, the value of atorvastatin would be expected to increase with the patient's risk for serious cardiovascular events.

Recent randomised trials have demonstrated a statistically significant effect of trastuzumab on disease-free survival when used as adjuvant therapy for human epidermal growth factor receptor 2 protein (HER2)-positive resectable early stage breast cancer, with a treatment course lasting either 9 or 52 weeks. However, the cost effectiveness of adjuvant trastuzumab with respect to mortality remains uncertain, especially in an Australian setting. ⋯ The results suggest that trastuzumab as adjuvant therapy for early breast cancer may be cost effective when given over either 52 or 9 weeks at current acquisition costs in Australia. However, the overall budget impact of the 52-week course is significant, and the 9-week course appears economically attractive.

Although there are estimated to be nearly 1 million cases of herpes zoster diagnosed in the US each year, the economic costs associated with herpes zoster in the US have not been well described. ⋯ The management of acute/subacute herpes zoster was found to result in substantial healthcare costs, with outpatient care and prescription drugs comprising the majority of the cost burden. To more fully understand the overall cost of herpes zoster disease to society, future studies should examine the healthcare costs associated with post-herpetic neuralgia and productivity losses due to herpes zoster and post-herpetic neuralgia.
