Comparative clinical and economic assessment of polatuzumab vedotin therapy in combination with bendamustine and rituximab for adult transplantation-ineligible patients with relapsed/refractory diffuse large B-cell lymphoma
Abstract
Aim. To evaluate the pharmacoeconomic feasibility of using polatuzumab vedotin in combination with bendamustine and rituximab for the treatment of adult transplantation-ineligible patients with relapsed/refractory diffuse large B-cell lymphoma.Materials and methods. Study design - retrospective analysis of literature data. Pharmacoeconomic research methods - clinical and economic analysis (incremental cost-effectiveness analysis, case-based approach) using sensitivity assessment. The sources of the drug efficacy data were publications on conducted clinical trials; on the drugs cost -the State register of maximum selling prices, data from the manufacturer's company.Results. Polatuzumab vedotin is the unique drug from the class of monoclonal antibody-antimitotic agent conjugates registered in Russia for the treatment of adult transplantation-ineligible patients with relapsed/refractory diffuse large B-cell lymphoma. for this reason a case-based approach was applied as part of the cost-effectiveness analysis. As a result of clinical and economic analysis, it was found that the cost of progression free life-year added when using polatuzumab vedotin in combination with bendamustine and rituximab in patients with relapsed/refractory diffuse large b-cell lymphoma by 50.7 %, or by 11.4 million rubles, lower than the cost of progression free life-year added when using brentuximab vedotin in patients with relapsed/refractory Hodgkin's lymphoma. The sensitivity assessment showed the stability of the obtained results to changes in the input parameters of treatment cost and efficacy in a wide range of values.Conclusion. Use of polatuzumab vedotin in combination with bendamustine and rituximab for the treatment of adult transplantation-ineligible patients with diffuse large B-cell non-Hodgkin's lymphoma is pharmacoeconomically justified and appropriate.
