What data supports the effectiveness of the drug combination Loncastuximab Tesirine and Rituximab for treating follicular lymphoma?
Rituximab, one of the drugs in the combination, has been shown to improve outcomes in patients with follicular lymphoma when added to chemotherapy, leading to longer periods without disease progression. It has also been effective as a single treatment in some cases, making it a valuable part of therapy for this type of cancer.
12345Is the combination of Loncastuximab Tesirine and Rituximab safe for treating follicular lymphoma?
The safety of Rituximab, a component of the treatment, has been well-studied in various trials for follicular lymphoma and other conditions. It is generally considered safe, with most patients experiencing some treatment-related side effects, but serious adverse events are less common. However, specific safety data for the combination of Loncastuximab Tesirine and Rituximab is not provided in the available research.
678910What makes the drug Loncastuximab Tesirine + Rituximab unique for treating follicular lymphoma?
Loncastuximab Tesirine is an antibody-drug conjugate that targets CD19, a protein on B-cells, and delivers a toxic payload directly to cancer cells, while Rituximab targets CD20 on B-cells to help the immune system destroy them. This combination offers a novel approach by using two different mechanisms to attack the cancer cells, potentially improving treatment effectiveness compared to standard therapies that typically use Rituximab with chemotherapy.

Rituximab: a review of its use in chronic lymphocytic leukaemia, low-grade or follicular lymphoma and diffuse large B-cell lymphoma. [2021]Rituximab (MabThera, Rituxan) is a chimeric mouse anti-human CD20 monoclonal antibody. This article reviews the use of intravenous rituximab in the treatment of chronic lymphocytic leukaemia (CLL), low-grade or follicular lymphoma, and diffuse large B-cell lymphoma. The addition of rituximab to fludarabine plus cyclophosphamide significantly prolonged progression-free survival both in previously untreated patients with CLL and in those with relapsed or refractory CLL, according to the results of two randomized, open-label, multicentre trials. In patients with previously untreated advanced follicular lymphoma, the addition of rituximab to chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone [CHOP], cyclophosphamide, vincristine and prednisone [CVP], mitoxantrone, chlorambucil and prednisolone, or cyclophosphamide, doxorubicin, etoposide and prednisolone) was generally associated with better outcomes than chemotherapy alone in randomized, multicentre trials. In a similarly designed trial, progression-free survival was significantly longer in previously untreated patients with follicular lymphoma, other indolent lymphomas or mantle-cell lymphoma who received rituximab plus bendamustine than in those receiving rituximab plus CHOP. Monotherapy with rituximab also demonstrated efficacy in patients with relapsed or refractory low-grade or follicular lymphoma, according to the results of noncomparative trials. In terms of maintenance therapy, progression-free survival was significantly prolonged with rituximab maintenance therapy versus observation alone in patients with advanced indolent lymphoma who had not progressed following first-line therapy with CVP and in patients with relapsed or refractory follicular lymphoma who had responded to CHOP (with or without rituximab), according to the results of randomized, open-label, multicentre trials. In four randomized, open-label, multicentre trials in younger or elderly patients with previously untreated diffuse large B-cell lymphoma, event-free survival, failure-free survival, progression-free survival and overall survival were generally improved to a significant extent by the addition of rituximab to CHOP or CHOP-like chemotherapy. Intravenous rituximab was generally well tolerated in patients with CLL, low-grade or follicular lymphoma, or diffuse large B-cell lymphoma, both as monotherapy and when administered in combination with chemotherapy. Infusion reactions were one of the most commonly occurring adverse events in patients receiving intravenous rituximab. The results of pharmacoeconomic modelling analyses demonstrated that rituximab appears to be cost effective in patients with previously untreated follicular lymphoma, in patients with follicular lymphoma receiving rituximab maintenance therapy following treatment for relapsed or refractory disease and in patients with previously untreated diffuse large B-cell lymphoma. In conclusion, rituximab remains a valuable therapy in patients with CLL, low-grade or follicular lymphoma and diffuse large B-cell lymphoma and, in a variety of treatment settings, represents the standard of care.

Biological therapy doublets: pairing rituximab with interferon, lenalidomide, and other biological agents in patients with follicular lymphoma. [2021]Rituximab (R) is a monoclonal antibody with high therapeutic efficacy in low-grade CD20+ lymphoma. The combination of R with chemotherapy is the most common treatment option for patients with follicular lymphoma (FL). The efficacy of R has also been shown to be augmented, when used in combinations with biologicals such as interferon-alpha-2a (IFN), bortezomib, or lenalidomide. The best combination of these drugs are not well defined and a better understanding of pharmacokinetics and timing of drugs relative to the rituximab infusion is crucial. Other new targeted agents, such as inhibitors of BTK and PI3Kdelta, have also been promising in FL. Translational research questions should be added to clinical trial protocols to increase the knowledge on how the tumor microenvironment and the host immune system affect the response to the different drugs and combinations with the aim of a more individualized therapy.
Rituximab: clinical development and future directions. [2019]The availability of effective monoclonal antibodies (mAbs) has revolutionised the management of patients with B-cell malignancies. The most widely studied of these agents is rituximab (Rituxan, IDEC Pharmaceuticals, San Diego, CA), a chimeric anti-CD20 antibody. Using the standard 4-weekly administration schedule, rituximab induces responses in almost half of patients with relapsed follicular/low-grade (F/LG) non-Hodgkin's lymphoma (NHL) with complete remissions in 6%. Lower response rates (RRs) have been noted in chronic lymphocytic leukaemia (CLL) using the standard dose and schedule. The drug has been well tolerated in most patients with common adverse events including mild to moderate fevers and chills and rare occurrences of a serious syndrome related to cytokine release and rapid tumour clearance. This antibody is also active against aggressive NHL, mantle cell NHL, post-transplant lymphoproliferative disorder (PTLD), lymphoplasmacytic NHL and hairy cell leukaemia and is also being evaluated in autoimmune disorders. Combinations of rituximab with chemotherapy regimens such as CHOP (cyclophosphamide, adriamycin, vincristine, predinisone) may alter the therapeutic paradigm for these diseases. The future promise of this antibody is a foundation on which to develop new strategies to increase the cure of patients with lymphoid malignancies.
Rituximab: a benchmark in the development of chemotherapy-free treatment strategies for follicular lymphomas. [2020]With the introduction of the anti-CD20 antibody rituximab, the outcome of patients with follicular lymphoma (FL) has greatly improved over the last two decades. First-line prolonged rituximab monotherapy is effective, achieving long-term remission and prolonged failure-free survival in some patients. Additionally, rituximab has been shown to synergize with chemotherapeutic and novel targeted agents alike with measurable gains in duration of response. As such, rituximab has made its mark in the treatment of FL and remains a valid agent despite the availability of newer monoclonal antibodies. This review summarizes the evolving role of rituximab as the first available anti-CD20 monoclonal antibody, emphasizing its clear activity as a single agent and in combination with chemotherapy or molecular targeted agents, and setting the standard for the development of new anti-CD20 monoclonal antibodies.
Long-term efficacy and safety of CT-P10 or rituximab in untreated advanced follicular lymphoma: a randomized phase 3 study. [2021]Rituximab biosimilars are a cornerstone of treatment of advanced-stage follicular lymphoma (FL). This double-blind, parallel-group, phase 3 trial randomized (1:1) adults (≥18 years) with stage III to IV indolent B-cell lymphoma, including grades 1 to 3a FL, to receive CT-P10 or rituximab (375 mg/m2 IV), with cyclophosphamide, vincristine, and prednisone, every 3 weeks for 8 cycles (induction period). Patients achieving complete response (CR), unconfirmed CR, or partial response (PR) received CT-P10 or rituximab maintenance for 2 years (375 mg/m2, every 8 weeks). Primary end points were previously reported, proving noninferiority of efficacy and pharmacokinetic equivalence of CT-P10 to rituximab. Secondary end points included overall response rate (PR+CR) during the induction period per 2007 International Working Group (IWG) criteria, survival analyses, and overall safety. Between 28 July 2014 and 29 December 2015, 140 patients were randomized (70 per group). Median follow-up was 39.9 months (interquartile range, 36.7-43.5). Per 1999 IWG criteria, 4-year Kaplan-Meier estimates (95% confidence interval [CI]) for CT-P10 and rituximab were 61% (47% to 73%) and 55% (36% to 70%) for progression-free survival (hazard ratio, 1.33 [95% CI, 0.67-2.63]; P=.409), respectively, and 88% (77% to 94%) and 93% (83% to 97%) for overall survival (5.29 [0.84-33.53]; P=.077). Overall, 90% (CT-P10) and 86% (rituximab) of patients experienced treatment-emergent adverse events. Long-term safety profiles were similar between groups. Findings confirm favorable outcomes for CT-P10-treated patients with advanced-stage FL and demonstrate comparable long-term efficacy and overall safety between CT-P10 and rituximab. This trial was registered at www.clinicaltrials.gov as #NCT02162771.
A phase 3 study of rituximab biosimilar HLX01 in patients with diffuse large B-cell lymphoma. [2021]Rituximab in combination with chemotherapy has shown efficacy in patients with diffuse large B-cell lymphoma (DLBCL) for more than 15 years. HLX01 was developed as the rituximab biosimilar following a stepwise approach to demonstrate biosimilarity in analytical, pre-clinical, and clinical investigations to reference rituximab. With demonstrated pharmacokinetic similarity, a phase 3 multi-center, randomized, parallel, double-blind study (HLX01-NHL03) was subsequently conducted to compare efficacy and safety between HLX01 plus cyclophosphamide, doxorubicin, vincristine, and prednisone (H-CHOP) and reference rituximab plus CHOP (R-CHOP) in a total of 407 treatment-naïve, CD20-positive DLBCL patients aged 18-80 years. The primary efficacy endpoint was best overall response rate (ORR) within six cycles of treatment in the per-protocol set (PPS). Secondary endpoints included 1-year efficacy outcomes, safety, and immunogenicity profile. The results showed difference in ORRs [H-CHOP 94.1%; R-CHOP 92.8%] between two treatment groups was 1.4% (95% confidence interval [CI], - 3.59 to 6.32, p = 0.608) which falls within the pre-defined equivalence margin of ± 12%. The safety profile was comparable between the treatment groups, with a similar overall incidence of treatment-emergent adverse events (H-CHOP 99.5%, R-CHOP 99.0%, p = 1.000) and serious adverse events (H-CHOP 34.0%, R-CHOP 32.5%, p = 0.752). This study established bioequivalence in efficacy and safety between HLX01 and reference rituximab. The trial was registered at http://www.chinadrugtrials.org.cn on 26 August 2015 [#CTR20150583].
Polatuzumab vedotin plus bendamustine and rituximab or obinutuzumab in relapsed/refractory follicular lymphoma: a phase Ib/II study. [2023]Follicular lymphoma (FL) is the most common type of indolent non-Hodgkin lymphoma. Despite treatment advances that have improved outcomes for patients with relapsed or refractory (R/R) FL, many patients still die from progressive disease or treatment-related toxicities. In the phase Ib/II GO29365 study (NCT02257567), the safety and efficacy of polatuzumab vedotin plus bendamustine and rituximab (Pola-BR) versus BR alone, and polatuzumab vedotin plus bendamustine and obinutuzumab (Pola-BG) as a single-arm cohort were evaluated in patients with R/R FL. Following the phase Ib safety run-in, patients were randomized 1:1 to receive Pola-BR or BR alone in the phase II stage; a separate non-randomized Pola-BG cohort was examined in the phase Ib/II expansion stage. Primary endpoints included safety and tolerability (phase Ib) and positron emission tomography complete response (PET-CR) rate by independent review committee (phase II). Overall, 112 patients were enrolled (phase Ib safety run-in: Pola-BR, n=6; phase II randomized cohort: Pola-BR, n=39; BR, n=41; phase Ib/II expansion cohort: Pola-BG, n=26). PET-CR rates were 66.7% (phase Ib safety run in, Pola-BR); 69.2% (phase II randomized, Pola-BR); 63.4% (phase II randomized, BR); and 65.4% (phase Ib/II expansion Pola-BG). There was a higher occurrence of cytopenias with Pola-BR and Pola-BG than with BR; serious adverse events were more frequent with Pola-BR (61.4%) and Pola-BG (46.2%) than with BR (29.3%). Overall, this analysis does not demonstrate a benefit of adding Pola to BR or BG regimens for patients with R/R FL.
Description of late onset neutropenia in indolent lymphoma patients treated with bendamustine plus rituximab. [2018]Bendamustine (B) associated with rituximab (R) is widely described in literature for the management of patients with chronic lymphoid leukaemia (CLL) and indolent non-Hodgkin lymphoma. Safety data regarding late hematotoxicity such as late onset neutropenia (LON) are scarce. The aim of our study was to assess the incidence and to identify risk factors for LON in patients with indolent non-Hodgkin lymphoma and CLL treated with B and R (B-R). One hundred forty five patients were treated with B-R as first or second line. Patients with neutropenia prior induction treatment, treated beyond second line and relapsing within 3 months after the end of induction treatment, were excluded. Patients receiving at least 1 cycle of B-R and having LON during follow-up period were included and considered as eligible for toxicity assessment. A complete blood count was performed 4 weeks after the last cycle of induction treatment and thereafter every 3 months for 1 year. Thirty six patients were identified in our cohort (incidence of 25%), mostly affected by CLL (n = 11) and follicular lymphoma (FL) (n = 15). During follow-up, 84 events of LON were recorded, 61% and 39% were of grades 1/2 and 3/4, respectively. No episode of febrile neutropenia was documented. Amongst 13 of the 15 patients with FL undergoing R maintenance, 8 had treatment discontinuation because of LON. Median time for LON (grade > 2) and time to recovery (grade 1. The LON in B-R treated patients is clinically relevant. Close clinical and biological follow-up and treatment prophylaxis (eg, valaciclovir and cotrimoxazole) especially for FL patients undergoing maintenance with R monotherapy seems relevant.
Efficacy and safety of rituximab biosimilars or reference product as first-line treatment in patients with low-tumour-burden follicular lymphoma: A systematic review and meta-analysis. [2022]The role of rituximab in the first-line treatment of low-tumour-burden follicular lymphoma (LTB-FL) has been supported by a large number of data. However, whether rituximab biosimilars have the same efficacy and safety as the reference drug (MabThera) is still controversial.
Rituximab: as first-line maintenance therapy following rituximab-containing therapy for follicular lymphoma. [2021]Rituximab is a recombinant chimeric murine/human monoclonal IgG(1-κ) antibody. It binds specifically to the CD20 antigen on normal and malignant B lymphocytes and produces complement-dependent and antibody-dependent cytotoxicity and induces apoptosis in these cells. Prolonged treatment with rituximab in patients with follicular lymphoma results in a sustained reduction in circulating B lymphocytes. Two years of single-agent maintenance therapy with rituximab significantly prolonged progression-free survival (primary endpoint) compared with observation in patients with follicular lymphoma who were responsive to first-line induction therapy with rituximab plus chemotherapy. Furthermore, maintenance therapy with rituximab significantly delayed the time to the next antilymphoma treatment and the next chemotherapy compared with observation in these patients. Rituximab had an acceptable tolerability profile as single-agent maintenance therapy in patients with follicular lymphoma with no new or unexpected adverse events compared with induction therapy.
Rituximab serum concentrations during immuno-chemotherapy of follicular lymphoma correlate with patient gender, bone marrow infiltration and clinical response. [2021]Treatment of follicular lymphoma with rituximab is currently recommended at a dose of 375 mg/m(2). We aimed to provide a rationale for optimal dosing and scheduling of this anti-CD20 antibody based on pharmacokinetics.
Rituximab: review and clinical applications focusing on non-Hodgkin's lymphoma. [2015]Rituximab (Rituxan) was the first monoclonal antibody approved for cancer therapy and the first single-agent approved for therapy of lymphoma. When combined with CHOP, rituximab is the only drug that has been shown to improve survival of a subpopulation of patients with diffuse large cell lymphoma during the last three decades. It was approved by the FDA for the treatment of patients with relapsed or refractory low-grade or follicular, CD20-positive, B-cell non-Hodgkin's lymphoma in 1997. Rituximab is also being studied in many other B-cell malignancies alone and in combination with other agents. Furthermore, it is currently being evaluated in several nonmalignant diseases, such as autoimmune disorders. This review will focus on the role of rituximab in patients with non-Hodgkin's lymphoma.
