Rituximab: a review of its use in non-Hodgkin's lymphoma and chronic lymphocytic leukaemia

Rituximab is an anti-CD20 monoclonal antibody that has demonstrated efficacy in patients with various lymphoid malignancies, including indolent and aggressive forms of B-cell non-Hodgkin's lymphoma (NHL) and B-cell chronic lymphocytic leukaemia (CLL). While the optimal use of the drug in many clinical settings has yet to be clarified, two pivotal trials have established rituximab as a viable treatment option in patients with relapsed or refractory indolent NHL, and as a standard first-line treatment option when combined with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) chemotherapy in elderly patients with diffuse large B-cell lymphoma (the most common type of aggressive NHL). The former was a noncomparative trial in relapsed indolent NHL (follicular and small lymphocytic subtypes) with clinical responses achieved in about half of patients treated with rituximab 375 mg/m(2) intravenously once weekly for 4 weeks, which was similar to some of the most encouraging results reported with traditional chemotherapeutic agents. The latter was a randomised comparison of eight cycles of CHOP plus rituximab 375 mg/m(2) intravenously (one dose per cycle) versus CHOP alone in previously untreated elderly patients (60 to 80 years of age) with diffuse large B-cell lymphoma. In this pivotal trial, 2-year event-free and overall survival were significantly higher with rituximab plus CHOP, and there was no increase in clinically significant adverse effects compared with CHOP alone. Treatment with rituximab is generally well tolerated, particularly in terms of adverse haematological effects and serious or opportunistic infections relative to standard chemotherapy. Infusion-related reactions occur in the majority of patients treated with rituximab; these are usually mild to moderate flu-like symptoms that decrease in frequency with subsequent infusions. In approximately 10% of patients, however, severe infusion-related reactions develop (e.g. bronchospasm, hypotension). These reactions are usually reversible with appropriate interventions and supportive care but there have been rare reports of fatalities. CONCLUSIONS: Clinical trials with rituximab indicate that the drug has broad application to B-cell malignancies, although further clarification is needed to determine its optimal use in many of these clinical settings. Importantly, rituximab in combination with CHOP chemotherapy has emerged as a new treatment standard for previously untreated diffuse large B-cell lymphoma, at least in elderly patients. Compared with conventional chemotherapy, rituximab is associated with markedly reduced haematological events such as severe neutropenia, as well as associated infections. Rituximab may be particularly suitable for elderly patients or those with poor performance status, and its tolerability profile facilitates its use in combination with cytotoxic drugs. PHARMACODYNAMIC PROPERTIES: Rituximab is a mouse/human chimaeric IgG(1)-kappa monoclonal antibody that targets the CD20 antigen found on the surface of malignant and normal B lymphocytes. Although treatment with rituximab induces lymphopenia in most patients, typically lasting about 6 months, a full recovery of B lymphocytes in the peripheral blood is usually seen 9-12 months after therapy, as CD20 is not expressed on haematopoietic stem cells. CD20 is, however, expressed on >90% of B-cell non-Hodgkin's lymphomas (NHL) and to a lesser degree on B-cell chronic lymphocytic leukaemia (CLL) cells.Although not fully elucidated, the cytotoxic effects of rituximab on CD20-positive malignant B cells appears to involve complement-dependent cytotoxicity, complement-dependent cellular cytotoxicity, antibody-dependent cellular cytotoxicity and induction of apoptosis. In addition, in vitro data indicate that rituximab sensitises tumour cells to the effects of conventional chemotherapeutic drugs. PHARMACOKINETIC PROPERTIES: Serum rituximab concentrations increased in proportion to dose across a wide range of single- and multiple-dose intravenous regimens in patients with B-cell NHL. When administll NHL. When administered at a dose of 375 mg/m(2) once weekly for 4 weeks in a pivotal trial in patients with relapsed or refractory indolent B-cell NHL (follicular or small lymphocytic subtypes), peak serum concentrations essentially doubled from the first (239.1 mg/L) to the fourth (460.7 mg/L) infusion, while elimination half-life (t(1/2)) increased from 76.3 to 205.8 hours (3.2 to 8.6 days). The concomitant increase in serum rituximab concentrations and t(1/2) with each successive infusion may be due, at least in part, to the elimination of circulating CD20-positive B cells and reduction or saturation of CD20-binding sites after the initial infusions of rituximab. The pharmacokinetic properties of rituximab are also characterised by wide inter-individual variability, and serum drug concentrations that are correlated with clinical response. Although pharmacokinetic data are limited in patients with aggressive forms of NHL, such as diffuse large B-cell lymphoma, rituximab appears to have a similar pharmacokinetic profile in these patients to that in patients with indolent B-cell NHL. The pharmacokinetics of rituximab are also reported to be similar whether the drug is administered with or without cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) chemotherapy. THERAPEUTIC USE: A number of studies have demonstrated efficacy of intravenous rituximab in patients with various lymphoid malignancies of B-cell origin, including indolent (e.g. follicular lymphoma) and aggressive (e.g. diffuse large B-cell lymphoma) forms of NHL, and CLL, but the drug has not yet been approved for use in CLL, and approved indications in NHL vary between countries. In the US, for example, rituximab is available for the treatment of patients with low-grade or follicular, relapsed or refractory, CD20-positive B-cell NHL. In Europe, the drug has similar approval for relapsed or refractory follicular NHL as in the US, but has also been approved for use in combination with CHOP chemotherapy for the most common aggressive form of NHL (CD20-positive, diffuse large B-cell lymphoma). Rituximab was approved for these indications primarily on the basis of results from two pivotal trials. In Japan, rituximab has been approved for indolent B-cell NHL and mantle cell lymphoma (an aggressive form of B-cell NHL), primarily on the basis of results of a Japanese phase II trial. Indolent NHL: Results of several studies evaluating rituximab 375 mg/m(2) once weekly for 4 weeks in patients with indolent forms of B-cell NHL (primarily follicular and small lymphocytic lymphomas) showed objective response (OR) rates ranging from approximately 40-60% in those receiving the drug for relapsed or refractory indolent B-cell NHL, and slightly higher (50-70%) for those receiving rituximab as first-line therapy. In a pivotal trial in 166 patients with relapsed or refractory low-grade or follicular B-cell NHL, intent-to-treat (ITT) analysis showed an OR rate of 48%, and a projected median time to progression of 13 months.Encouraging data are also emerging on the use of rituximab in combination with chemotherapeutic agents (e.g. CHOP, fludarabine-containing regimens) or other drugs (e.g. interferon-alpha2a) in previously untreated patients with indolent forms of B-cell NHL (primarily follicular and small lymphocytic subtypes). Rates for OR were consistently around 95%, with the majority being complete responses (CRs). Follow-up data from a study in 40 patients with low-grade or follicular B-cell NHL treated with rituximab plus CHOP as first-line therapy showed that responses were durable with a progression-free survival and median duration of response >5 years.Bcl-2 gene rearrangement (t14;18) occurs in malignant cells in up to 85% of patients with follicular lymphoma, and minimal residual disease in peripheral blood and bone marrow can be monitored using polymerase chain reaction (PCR). In several studies assessing blood and/or bone marrow, rituximab has achieved molecular response (conversion from PCR-positive to PCR-negative bcl-2 status) in at least half of the patients. Aggressive NHL: Studies with rituximab as monotherapy in aggressive B-cell NHL, a potentially curable disorder, have generally been restricted to patients with relapsed or recurrent disease, since CHOP has traditionally been the standard first-line treatment regimen. However, promising results from phase II monotherapy studies prompted further clinical investigation of rituximab in conjunction with chemotherapy. Thus, most studies with rituximab in patients with aggressive forms of B-cell NHL have involved combination therapy, including a pivotal randomised trial comparing eight cycles of standard CHOP therapy plus rituximab 375 mg/m(2) (one dose per cycle) versus CHOP alone in 399 previously untreated elderly patients (60-80 years of age) with diffuse large B-cell lymphoma. Results of the pivotal trial showed a clear advantage for rituximab plus CHOP versus CHOP in terms of event-free survival (primary endpoint) at 2 years (57% vs 38%, p < 0.001). Overall survival at 2 years (70% vs 57%, p < 0.01) and CR rate (76% vs 63%, p < 0.01) were also higher with the rituximab-CHOP combination. Other, smaller trials with rituximab in combination with CHOP or other chemotherapeutic regimens, either as first-line therapy or for patients with relapsed or refractory aggressive B-cell NHL, have also shown promising results in terms of clinical response rates.CLL: In relatively small trials (n < 40) conducted primarily in patients with relapsed or refractory B-cell CLL, rituximab monotherapy (various regimens) achieved OR rates of 23-45%, with median duration of response ranging from approximately 3-10 months.

Rituximab in B-cell disorders other than non-Hodgkin's lymphoma

Rituximab is a human/mouse chimeric monoclonal antibody that binds to the CD20 antigen and is expressed at all stages of B-cell development. Rituximab has demonstrated efficacy as monotherapy and in combination with chemotherapy in the treatment of both indolent and aggressive non-Hodgkin's lymphoma (NHL). Rituximab treatment results in rapid depletion of B-cells and this has led to the consideration of other B-cell disorders as candidates for rituximab therapy. Recent studies have demonstrated the efficacy of rituximab in a variety of such disorders, including chronic lymphocytic leukemia (CLL), post-transplant lymphoproliferative disorder (PTLD), Waldenstr?m's macroglobulinemia (WM), multiple myeloma (MM), idiopathic thrombocytopenic purpura (ITP), hairy-cell leukemia (HCL) and cold agglutinin disease (CAD). In patients with CLL, increasing the dose and/or frequency of rituximab treatment has given improved response rates compared with the standard dose schedule used in NHL, and combination immunochemotherapy has yielded an overall response rate of 92% (with a 60% complete response rate). Clinical trials have also demonstrated evidence of efficacy for rituximab in PTLD, WM and relapsed or refractory ITP. Efficacy of rituximab in CAD and relapsed or refractory HCL has also been demonstrated in small studies and case reports. Available data thus indicate that rituximab can be an effective therapy in a wide range of CD20+ lymphoid disorders.

Rituximab: an innovative therapy for non-Hodgkin's lymphoma.

The epidemiology, etiology, classification, and treatment of non-Hodgkin's lymphoma (NHL) are reviewed, and rituximab, a newly available therapy, is discussed. NHL comprises a group of lymphoproliferative disorders the frequency of which continues to rise. Although many classification systems exist for identifying specific histological subtypes, NHL is generally divided into indolent (low-grade) and aggressive (intermediate- and high-grade) forms. Low-grade NHL is characterized by a slowly progressive, continually relapsing course, with eventual transformation to a more rapidly progressive form that is usually fatal. Several options are available for the management of indolent NHL; none is curative. Rituximab, a human-mouse monoclonal antibody that targets the CD20 antigen expressed in over 90% of B-cell NHLs, provides an alternative to conventional chemotherapy that is relatively safe and effective. In a Phase III trial involving 166 patients with relapsed or refractory low-grade B-cell NHL, rituximab produced an overall response of 48%, with 20 of 80 responders still in remission more than 36 months after treatment. Study results in patients with bulky disease and those requiring retreatment have also been encouraging. Most adverse effects associated with rituximab are mild to moderate. Infusion-related reactions occur more commonly during initial infusions and in patients with evidence of increased tumor burden but can be effectively managed with premedication, supportive care, and adjusted infusion rates. Hematologic effects are generally mild and transient, and adverse immune responses are rare. Rituximab is an alternative to conventional chemotherapy for the treatment of relapsed or refractory low-grade or follicular CD20-positive B-cell NHL.     

Semi-extended, six weekly rituximab infusions in pre-treated advanced low-grade B cell non-Hodgkin's lymphoma: a phase II study

Either four or eight weekly rituximab infusions in relapsed or refractory low-grade or follicular B cell non-Hodgkin's lymphoma (NHL) are well tolerated and efficacious. This phase II trial investigated the safety and efficacy of six weekly rituximab doses in chemotherapeutically pre-treated relapsed or refractory low-grade NHL patients. Sixty-eight patients (median age 64 years) received six i.v. rituximab infusions 375 mg/m2 weekly. All patients had received one or more prior therapies (median 2; range 1-18). Forty-two patients had progressive disease and were evaluated for toxicity and efficacy; 12 of these required re-treatment with six weekly rituximab infusions. Twenty-six patients received rituximab as remission consolidation therapy and were assessed for toxicity only. No patients discontinued because of adverse events. Most adverse events were National Cancer Institute grade 1 (2-9%) or 2 (3-5%) and usually occurred during the first infusion. No hematological abnormalities were observed. Overall response rate was 59% (median time to response 2 weeks) and 10 of 12 re-treated patients responded. Median time to progression for all patients was 14 months and for responders 21 months. More than half the 42 patients evaluated for efficacy and more than 70% of the 25 responding patients still survived longer than 3 years after treatment. The safety profile and efficacy achieved in this study compare favorably with those seen with four or eight weekly doses in pre-treated low-grade NHL.
