Abstract

AbstractObjectiveTo assess the cost-utility of collagen-polyvinyl pyrrolidone (collagen-PVP), a new drug developed and manufactured in Mexico, compared to non-steroidal anti-inflammatory drugs in the treatment of patients with knee osteoarthritis (OA) in Mexico.MethodsA probabilistic Markov model with a lifetime horizon was designed to evaluate the costs and outcomes (QALYs) of collagen-PVP compared to NSAIDs in patients with OA. Data from randomized clinical trials conducted in México were obtained as input for probabilities. Utility values ​​were elicited from international publications and costs information and service utilization was obtained from official publications of the Instituto Mexicano de Seguro Social - IMSS. Cost per quality-adjusted life-years was calculated by using the Mexican Healthcare payer perspective. A discount rate of 5% for both cost and outcomes was used. Sensitivity analyzes were performed with variations in the parameters of gender, age, and price of collagen-PVP.ResultsPatients treated with collagen-PVP showed a gain of 6.62 QALYs compared with 5.36 in patients with NSAIDs. The cost-utility ratio was higher in the NSAID group (MEX$ 170,010.76/QALY) compared to collagen-PVP (MEX $ 130,953.63/QALY). The incremental cost-utility ratio was MEX $ 35,194.16.ConclusionsThis is the first economic evaluation of a new medication developed in Mexico and conducted partially with local data. The results of this study allow concluding that collagen-PVP is deemed as the dominant alternative compared with NSAIDs in the treatment of knee osteoarthritis
