Omalizumab worth it in severepersistent asthma
Omalizumab provides cost offsets, improves QOL,and has an "attractive" incremental cost effectivenessratio (ICER) when compared with standard care amongpatients with severe persistent allergic asthma inSweden, according to a multinational group ofinvestigators.
To assess the cost effectiveness of addingomalizumab to optimised standard therapy among suchpatients who remained uncontrolled on GINA* 2002step 4 therapy, the investigators developed a Markovmodel using efficacy data obtained from the 28-weekINNOVATE trial and Swedish life table and cost data.**
The model had a lifelong time horizon and assumedpatients to enter at age 40 years; the treatment effect ofomalizumab was modelled constantly for 5 years, afterwhich all patients would revert to standard therapyalone.
The base-case analysis showed that the addition ofomalizumab would be associated with an additionallifetime cost of €42 754 for a gain of 0.762 quality-adjusted life-years (QALYs) versus standard therapyalone.† This would represent an ICER of €56 091 perQALY gained for omalizumab compared with standardtherapy. The accepted cost per QALY gained threshold is€53 384 in Sweden, the investigators note.
Sensitivity analyses revealed the model to be mostsensitive to changes in asthma fatality rate, patientadherence to treatment, and independence of futureasthma exacerbations from previous events.* Global Initiative for Asthma** The study was supported by a grant from Novartis, with which twoof the investigators were affiliated.† Costs were those associated with drug acquisition, physician visits,exacerbations, hospitalisation, and added years of life. Costs andoutcomes were discounted at an annual rate of 3%, and werecalculated from a societal perspective.
