Tipranavir cost effective intreatment-experienced HIV
The incremental cost-effectiveness ratio (ICER) forritonavir-boosted tipranavir falls within the acceptablerange of $US50 000–$US100 000 for treatment-experienced patients with HIV infections, according to astudy* presented at the 11th International Meeting ofthe International Society for Pharmacoeconomics andOutcomes Research.
They used a Markov model to assess the costeffectiveness of the ritonavir-boosted tipranavir usingdata from the 48-week RESIST 1 (n = 620) and 2(n = 863) trials, in which the safety and efficacy ofritonavir-boosted tipranavir were compared withritonavir-boosted comparator protease inhibitors (PI) inpatents who had received at least two PI-based regimensand three classes of antiretrovirals; comparator PIsincluded amprenavir, fosamprenavir, lopinavir, indinaviror saquinavir. Costs** were estimated in 2005 US dollarsfrom the US payer perspective; costs and life expectancywere discounted at 3%.
Over 5 years, the rate of AIDS-defining eventsdecreased by 12.35% for patients receiving ritonavir-boosted tipranavir, which led to cost offsets of$US7086. Compared with comparator PI recipients,tipranavir recipients gained 7.7 quality-adjusted lifemonths, at an additional cost of $US36 188. The ICER ofritonavir-boosted tipranavir versus ritonavir-boostedcomparator PI was $US56 315 per quality-adjusted lifeyear (QALY) gained. ICER decreased to $US49 563 perQALY gained for patients who had not receivedenfuvirtide as an optimised background regimen.Sensitivity analyses showed that the ICER of ritonavir-boosted tipranavir was in the range of$US48 874–$US60 325 per QALY gained.* sponsored by Boehringer Ingelheim** Costs included drug prices and costs of patient monitoring andAIDS-defining events.
