Brief Summary:
Combination of rituximab (RTX) with several different chemotherapeutic regimes has proven synergistic effects in patients with either lymphoma or autoimmune diseases. First data of uncontrolled trials with the combination of RTX and leflunomide (LEF) are available.
Detailed Description:
Rituximab provides lasting improvement in the signs and symptoms of rheumatoid arthritis (RA) after two infusions per treatment course in tumor necrosis factor (TNF) inhibitor inadequate responder (IR) patients. Importantly, MabThera® has been shown to inhibit radiographic progression in this highly pre-treated patient population. Rituximab is licensed for adult patients with severe active RA in combination with methotrexate after inadequate response to previous treatment, including TNF alpha- Inhibitors.
In daily practice the combination with methotrexate is often limited to side effects or contraindications to Methotrexate (MTX). Therefore there is an unmet medical need for evidence for the combination of RTX with other Disease modifying anti-rheumatic drugs (DMARDs)than MTX.
Leflunomide is a DMARD that selectively inhibits de novo pyrimidine synthesis by blocking the enzyme dihydro-orotate dehydrogenase, thereby preventing DNA synthesis. The efficacy and safety of leflunomide in patients with active RA have been demonstrated in three phase III studies. Leflunomide was shown to be better than placebo and at least as effective as methotrexate in improving individual signs and symptoms of RA; these responses were seen as early as 4 weeks and were maintained for up to 2 years. Leflunomide was also effective in slowing disease progression as assessed by radiographic analysis of joint damage, and in improving functional activity as measured by the Stanford Health Assessment Questionnaire Disease Activity Index. An open label extension study of patients treated with leflunomide demonstrated that these improvements are maintained for up to 5 years in a subset of patients, with no new or unexpected adverse events emerging compared with the initial phase III studies.
In Europe leflunomide is often used in daily clinical practice as an alterative to MTX in patients with active RA.
Recently published data of a small open label trial (Vital et al. 2008) and data of a German non-interventional study (NIS) (Wendler et al. 2009) demonstrated the effectiveness of the addition of RTX to leflunomide in patients with active RA. The proportion of patients achieving EULAR (European League against Rheumatism) moderate to good response was 61% for RTX alone, 65 % for RTX plus MTX and 79% for RTX plus leflunomide in the German NIS. In the Leeds study of Vital et al.
33% of the patients achieved ACR (American College of Rheumatology)50 response (ACR 20: 68%, ACR 70: 20%) despite multiple pre-treatments, including patients with inadequate response to three TNF-Inhibitors.
The low rate of serious adverse drug reactions in the different groups of the German NIS demonstrated the safety of the combination of RTX and leflunomide (n=90) (1.6 / 1.1 / 0,5% for RTX+MTX / RTX+LEF / RTX Mono, 5.1 / 6,7 / 3,8% experienced infusion reactions)
