Evaluation of the Effectiveness of Kits Promonitor-IFX/ADL and Promonitor-Anti-IFX/ADL in Patients With IBD

Overview

To establish the efficacy, safety, effectiveness and efficiency of monitoring the levels of anti-TNFα drugs and the levels of antibodies generated against these drugs in the treatment of patients with moderate or severe IBD (CD/CU). An analysis will be made of the economic impact on the Health System of monitoring treatment with anti-TNFα drugs in CD/CU. As a result of this specific objective, a standardized procedure will be established for the evaluation of the response to treatment with anti-TNFα drugs for CD/CU that includes the new trials and the new devices developed.

* To evaluate whether a dose and plasma level optimization strategy based on the use of Promonitor-IFX, Promonitor-Anti-IFX, Promonitor-ADL, and Promonitor-Anti-ADL kits in CD/CU patients on IFX/ADL treatment is superior in terms of the percentage of patients in clinical remission at 12 months compared to standard practice. * To evaluate whether a dose and plasma level optimization strategy based on the use of Promonitor-IFX, Promonitor-Anti-IFX, Promonitor-ADL, and Promonitor-Anti-ADL kits in CD/CU patients on IFX/ADL treatment is superior in terms of the percentage of patients in deep remission at 12 months compared to standard practice. * To analyze the influence of the use of the IFX/ADL antibody detection test in moderate to severe CD/CU patients on the annual direct cost to the health system of these patients, compared to the non-use of the tests. * To evaluate the effectiveness of IFX/ADL antibody testing in moderate to severe CD/CU patients on the increase in quality-adjusted life-years compared to non-use of the tests. * To evaluate the effectiveness of testing for antibodies to IFX/ADL in moderate to severe CD/CU patients in reducing the number of flares, compared to not using the tests. Exploratory objective - To conduct a cost-effectiveness (utility) analysis of a strategy for the management of stable moderate to severe CD/CU patients based on treatment monitoring. Page 10 of 83 anti-TNFα with the introduction of screening tests for plasma levels/antibodies to IFX/ADL with respect to standard practice based on clinical signs/symptoms. Main operational objective \- To assess whether the prevalence of 1-year remission in moderate to severe CD/CU patients whose anti-TNFα treatment has been managed using Promonitor IFX/ADL kits is at least 16% higher compared to the group of patients in whom this technique has not been employed.
