Rituximab plus chemotherapy has been shown to be effective in patients with advanced-stage, previously untreated follicular lymphoma; nevertheless, most patients will have a relapse. Combination immunotherapy with lenalidomide and rituximab is an immunomodulatory regimen that has shown promising activity in patients with indolent B-cell non-Hodgkin's lymphoma.
To describe a single centre experience using combination therapy with rituximab (RTX) and mycophenolate mofetil (MMF) in a prospective series of systemic sclerosis (SSc) patients with pulmonary and cutaneous involvement, rapidly progressive or resistant to conventional therapy.
Phase 2 trial of bortezomib in combination with rituximab plus hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone alternating with bortezomib, rituximab, methotrexate, and cytarabine for untreated mantle cell lymphoma.
Although the outcomes of patients with mantle cell lymphoma (MCL) have improved, there is still no cure. Bortezomib has a 33% response rate in relapsed/refractory MCL and has shown additive and/or synergistic effects in preclinical trials with known effective agents.
Epstein-Barr virus (EBV) reactivation is an unresolved medical issue after allogeneic hematopoietic stem cell transplantation (HSCT). Rituximab treatment is recommended for EBV reactivation after HSCT but the number of doses of rituximab to use is unclear. In this study, risk factors and outcomes of patients who needed 1 dose vs >1 doses of preemptive rituximab to clear EBV viremia were compared. A higher viral load was more likely to be associated with higher doses of rituximab. Patients whose EBV viremi...
B cell depletion, most commonly with rituximab, is an evolving therapeutic approach in SLE. Infusion reactions after rituximab are common, and may prevent re-treatment in patients who previously demonstrated beneficial response. We have used ofatumumab, a fully humanized anti-CD20 mAb, as an alternative B cell-depleting agent in patients with SLE who are rituximab-intolerant due to severe infusion reactions.
Methotrexate treatment has been linked with an increased risk of melanoma. However, a possible dose-response relationship with respect to methotrexate exposure and melanoma has not been addressed. The aim of the present study was to investigate whether higher accumulated doses of methotrexate correlate with an increased risk of melanoma, which would further support a possible association. A nationwide retrospective cohort study was conducted. All Swedish patients over 18 years of age who were dispensed meth...
Methotrexate (MTX) is commonly used in the treatment of patients with moderate to severe psoriasis.
Background Single-agent ibrutinib has shown substantial activity in patients with relapsed Waldenström's macroglobulinemia, a rare form of B-cell lymphoma. We evaluated the effect of adding ibrutinib to rituximab in patients with this disease, both in those who had not received previous treatment and in those with disease recurrence. Methods We randomly assigned 150 symptomatic patients to receive ibrutinib plus rituximab or placebo plus rituximab. The primary end point was progression-free survival, as as...
Diffuse large B cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma. The treatment response and overall survival (OS) improved after incorporating rituximab with chemotherapies. Yet, available evidence as to whether women and men may benefit similarly from rituximab have not been adequately addressed, particularly in the real-world setting. The objective of this study was to examine sex differences in the clinical outcomes of rituximab in DLBCL patients using the Taiwan Cancer Registry Database an...
Osteosarcoma is the most common primary bone tumor in children, and only 1 article in the literature describes a case of osteosarcoma in a patient with Down syndrome. Although osteosarcoma is generally treated with chemotherapy regimens that include high-dose methotrexate, patients with Down syndrome have heightened sensitivity to the toxicities of methotrexate. The patient from the aforementioned case study died from sepsis soon after treatment with high-dose methotrexate. This case report describes the su...
Efficacy and safety of certolizumab pegol in combination with methotrexate in methotrexate-inadequate responder Chinese patients with active rheumatoid arthritis: 24-week results from a randomised, double-blind, placebo-controlled phase 3 study.
To evaluate the efficacy and safety of certolizumab pegol (CZP) in combination with methotrexate (MTX) in Chinese patients with active rheumatoid arthritis (RA) and an inadequate response to MTX.
This extension study provided continued treatment to subjects with active rheumatoid arthritis who had participated for ≥16 weeks in a pharmacokinetic similarity study of PF-05280586 (potential rituximab biosimilar). Objectives were to evaluate overall pharmacokinetics, pharmacodynamics, immunogenicity, safety, and tolerability of PF-05280586 after transition from a licensed rituximab product to PF-05280586, and followup of biomarker and efficacy assessments.
Venetoclax is a selective, potent inhibitor of the anti-apoptotic BCL-2 protein approved for treatment of chronic lymphocytic leukemia. We conducted a dose-finding study of venetoclax in combination with bendamustine-rituximab (BR) in patients with relapsed/refractory non-Hodgkin's lymphoma (NHL).
Eradication of factor VIII (FVIII) specific neutralizing antibodies (also known as inhibitors) by the traditional method of immune tolerance induction (ITI) is costly and unsuccessful in one out of three patients. Furthermore, effective inhibitor prevention strategies are presently lacking. An overview is given in this narrative review of antidrug antibody prevention or eradication strategies that have been used in disorders beyond hemophilia A, with the aim of analyzing what we can learn from these strateg...
This multinational, randomized, double-blind trial, (ClinicalTrials.gov identifier NCT02149121) was designed to demonstrate equivalence in pharmacokinetics and efficacy between CT-P10 and innovator rituximab (RTX) in patients with rheumatoid arthritis (RA). Adults with active RA were treated with CT-P10, United States-sourced RTX (US-RTX; Rituxan®), or European Union-sourced RTX (EU-RTX; MabThera®) at weeks 0 and 2. The co-primary pharmacokinetic endpoints were area under the serum concentration-time curv...
Patients with active ulcerative colitis (UC) failing conventional therapies are in need of rescue strategies. Due to the fact that accepted step-up therapy with biologicals is expensive and sometimes unavailable, alternative therapies are warranted. Methotrexate (MTX) and thioguanine (TG) have both been suggested as alternative maintenance strategies in conventional thiopurine failing UC patients. In this multicenter database study, we compared safety and effectiveness (drug-survival) of MTX and TG in UC pa...
Recently, a new disease of lymphocyte homeostasis caused by somatic mosaicism for the RAS mutation has been discovered (known as RALD, RAS-associated leukoproliferative disorder). Since few cases have been reported in literature, the prognosis and standard treatment for autoimmune diseases associated with RALD remain poorly understood. Standard rituximab therapy (375 mg/m for 4 wk) is effective in patients with autoimmune diseases, but early recurrences are common. We highlight the potential for monthly...
To report clinical experience with methotrexate (MTX) treatment for suspected but not definite ectopic pregnancy (EP).
The plasma concentrations of methotrexate (MTX) and its major metabolite 7-hydroxy methotrexate (7-OH-MTX) are highly correlated with the toxicities in patients with high-dose MTX therapy. Routine monitoring of MTX and 7-OH-MTX plasma levels is useful for dose adjustment of rescue drugs and toxicity prevention. A UHPLC-MS/MS method for simultaneous determination of plasma MTX and 7-OH-MTX was developed, validated, and applied in 181 plasma samples. The ion transition was m/z 455.2 → 308.2 for MTX and m/z ...
Recent reports have described the efficacy of rituximab in treating steroid-dependent nephrotic syndrome (SDNS) in pediatric patients. However, few reports describe data regarding adult-onset SDNS. We investigated the efficacy of rituximab for the management of adult-onset SDNS.
To investigate the added value of MTX-HCQ combination therapy (CTG) in early RA in a controlled cohort study. MTX monotherapy (MTG) is recommended as (part of) first choice treatment but no head-to-head comparisons are available comparing MTX-HCQ CTG with MTG.
This study aimed to explore whether peak serum methotrexate concentration (C) correlated with adverse events, overall survival (OS) and event-free survival (EFS) in patients with primary extremity osteosarcoma.
The GO-DACT is an investigator-initiated, national, multicentric randomized placebo-controlled double-blinded trial, that assesses dactylitis as primary endpoint. Psoriatic arthritis patients naïve to methotrexate and biologic disease modifying anti-rheumatic drugs, with at least one active dactylitis, were assigned to golimumab in combination with methotrexate or placebo in combination with methotrexate, for 24 weeks. Both clinical (dactylitis severity score and the Leeds dactylitis index) and imaging (hi...
Rituximab is an anti-CD20 antibody used to deplete B lymphocytes in lymphoma and autoimmune disease. Case reports in the literature describe patients who paradoxically develop autoimmune disease in response to rituximab therapy. We review the reports of autoimmune pathology in response to rituximab treatment and the proposed mechanisms of this reaction. These autoimmune diseases manifest in various organ systems, most frequently the skin and lungs, and involve distinct mechanisms of pathogenesis mediated by...
Subacute cutaneous lupus erythematosus is rare in children. Most patients respond well to conventional therapy with prednisone, hydroxychloroquine, or both. Other case reports and small series have reported successful clearance with rituximab in adults. We report an adolescent who obtained remission with rituximab after failing conventional therapy.
