Rituximab causes depletion of the B cell pool in 70-80% of patients and a decrease in serum immunoglobulin concentrations in a small number of patients. Bacterial, viral, fungal infections and infections of unspecified etiology (weight, regardless of cause) develop in 30.3% of patients. Severe infections (grades 3 and 4), including sepsis, were noted in 3.9% of patients.
Maintenance therapy (non-Hodgkin's lymphoma) up to 2 years
An increase in the overall incidence of infections, including grade 3-4 infections, was observed with rituximab therapy. There was no increase in the incidence of infectious complications with maintenance therapy lasting 2 years.
Fatal progressive multifocal leukoencephalopathy (PML) has been reported in patients with non-Hodgkin's lymphoma after disease progression and re-treatment.
Rituximab in combination with chemotherapy according to the following regimens: R-CVP for non-Hodgkin's lymphoma; R-CHOP for diffuse large B-cell non-Hodgkin lymphoma; R-FC for chronic lymphocytic leukemia
There was no increase in the incidence of infections or infestations with rituximab R-CVP regimen. Upper respiratory tract infections were the most common (12.3% in the R-CVP group). Serious infections occurred in 4.3% of patients receiving R-CVP chemotherapy; No life-threatening infections were reported. The proportion of patients with grade 2-4 infections and/or febrile neutropenia in the R-CHOP group was 55.4%. The total incidence of grade 2-4 infections in the R-CHOP group was 45.5%. The frequency of fungal infections of grade 2-4 in the R-CHOP group was higher than in the CHOP group due to a higher frequency of local candidiasis and amounted to 4.5%. The incidence of grade 2-4 herpes infection was higher in the R-CHOP group than in the CHOP group and was 4.5%.
In patients with chronic lymphocytic leukemia, the incidence of hepatitis B (exacerbation and primary infection) of grade 3-4 severity in the R-FC group was 2%.
From the blood system
Rituximab monotherapy (for 4 weeks)
Severe thrombocytopenia (grades 3 and 4) was observed in 1.7% of patients, severe neutropenia - in 4.2% of patients, and severe anemia (grades 3 and 4) - in 1.1% of patients.
Maintenance therapy (non-Hodgkin's lymphoma) up to 2 years
Leukopenia (grades 3 and 4) was observed in 5% of patients, and neutropenia (grades 3 and 4) in 10% of patients receiving rituximab. The incidence of thrombocytopenia (grade 3-4) was low and amounted to
Approximately 50% of patients for whom B-cell recovery data were available took 12 months or more to recover B-cell counts to normal levels after completion of rituximab induction therapy.
Rituximab in combination with chemotherapy according to the following regimens: R-CVP for non-Hodgkin's lymphoma; R-CHOP for diffuse large B-cell non-Hodgkin lymphoma; R-FC for chronic lymphocytic leukemia
Severe neutropenia and leukopenia: In patients receiving rituximab in combination with chemotherapy, grades 3 and 4 leukopenia were observed more often than in patients receiving chemotherapy alone. The incidence of severe leukopenia was 88% in patients receiving R-CHOP and 23% in patients receiving R-FC. The incidence of severe neutropenia was 24% in the R-CVP group, 97% in the R-CHOP group, and 30% in the R-FC group in previously untreated chronic lymphocytic leukemia. The higher incidence of neutropenia in patients receiving rituximab and chemotherapy was not associated with an increased incidence of infections and infestations compared with patients receiving chemotherapy alone. In patients with recurrent or chemoresistant chronic lymphocytic leukemia after treatment according to the R-FC regimen, in some cases, neutropenia was characterized by a long course and later manifestations.
Severe anemia and thrombocytopenia (grades 3 and 4): there was no significant difference in the incidence of anemia of grades 3 and 4 between groups. In the R-FC group, in the first line of treatment for chronic lymphocytic leukemia, anemia of grades 3 and 4 occurred in 4% of patients, thrombocytopenia of grades 3 and 4 - in 7% of patients. In the R-FC group with recurrent or chronic lymphocytic leukemia, anemia of grades 3 and 4 occurred in 12% of patients, thrombocytopenia of grades 3 and 4 - in 11% of patients.

Maintenance therapy (non-Hodgkin's lymphoma) up to 2 years
The incidence of grade 3 and 4 cardiovascular events was similar in patients receiving rituximab and those not receiving it. Serious cardiovascular events occurred in less than 1% of patients not receiving rituximab and in 3% of patients receiving the drug (atrial fibrillation in 1%, myocardial infarction in 1%, left ventricular failure in
Rituximab and combinations with chemotherapy according to the following regimens: R-CVP for non-Hodgkin's lymphoma; R-CHOP for diffuse large B-cell non-Hodgkin lymphoma; R-FC for chronic lymphocytic leukemia
The incidence of grade 3 and 4 cardiac arrhythmias, mainly supraventricular arrhythmias (tachycardia, atrial flutter and atrial fibrillation), was higher in the R-CHOP group and amounted to 6.9%. All arrhythmias developed either in connection with rituximab infusion or were associated with predisposing conditions such as fever, infection, acute myocardial infarction, or concomitant diseases of the respiratory and cardiovascular systems. The R-CHOP and CHOP groups did not differ in the incidence of other grade 3 and 4 cardiac adverse events, including heart failure, myocardial disease, and manifestation of coronary artery disease.
The overall incidence of grade 3 and 4 cardiovascular events was low both in first-line treatment of chronic lymphocytic leukemia (4% in the R-FC group) and in the treatment of relapsed/chemoresistant chronic lymphocytic leukemia (4% in the R-FC group).

Information on the post-registration use of rituximab for non-Hodgkin's lymphoma and chronic lymphocytic leukemia

From the skin and its appendages: rarely - severe bullous reactions, toxic epidermal necrolysis and Stevens-Johnson syndrome, in some cases with death.
From the nervous system: rarely - neuropathy of the cranial nerves in combination with peripheral neuropathy or without it (marked decrease in visual acuity, hearing, damage to other sensory organs, paresis of the facial nerve) during various periods of therapy up to several months after completion of the course of treatment with rituximab . Cases of posterior reversible encephalopathy (PRES)/posterior reversible leukoencephalopathy syndrome (PRLS) have been reported in patients treated with rituximab. Symptoms included blurred vision, headache, seizures and mental disturbances, with or without increased blood pressure. The diagnosis of PRES/PRLS can be confirmed using brain imaging techniques.

Cases of overdose in humans have not been observed. Single doses of rituximab above 1000 mg have not been studied. The maximum dose of 5000 mg was prescribed to patients with chronic lymphocytic leukemia, no additional safety data were obtained. Due to the increased risk of infectious complications when the pool of B-lymphocytes is depleted, infusions should be canceled or reduced, and the need for a comprehensive general blood test should be considered.
