INSTRUCTION FOR THE SPECIALIST.

Description of the drug approved by the manufacturer for the printed edition of 2017.

PHARMACHOLOGIC EFFECT

Antitumor drug.

Mechanism of action

Obinutuzumab is a recombinant, humanized, type II monoclonal antibody with a modified glycosylation scheme belonging to the IgG1 class and having a specificity for the CD20 antigen.
Obinutuzumab selectively interacts with the extracellular region of the transmembrane CD20 antigen located on the surface of normal and malignant mature B lymphocytes and their precursors, but does not bind to stem hemopoietic cells, pro-B lymphocytes, plasma cells, or other normal tissues.
Due to the modification of the glycosylation scheme of the Fc fragment, prenutuzumab has an increased affinity for the Fc? RIII receptors on the surface of the effector cells of the immune system, in particular natural killers, macrophages and monocytes, compared to antibodies that did not undergo such a modification.

Obinutuzumab directly induces cell death, mediates antibody-dependent cellular cytotoxicity (AZPC), and antibody-dependent cellular phagocytosis (AZKF) by attracting FcО±RIII-positive effector cells of the immune system.
In addition, prenutuzumab in low degree induces complement-dependent cytotoxicity (CCC).Compared to anti-CD20 antibodies of type I, ponotusumab (type II antibody) has an increased ability to directly induce cell death in the background of a decreased ability to cause CCD. Due to the modification of the glycosylation regimen, ponutunuzumab more effectively induces AZKTS and AZKF compared to anti-CD20 antibodies that did not undergo such a modification, which is manifested in more severe depletion of the B-cell pool and increased antitumor activity.
Depletion of the CD19 + B-cell pool (up to <0.07? 10 9 / L) was observed in 91% of patients with chronic lymphocytic leukemia (CLL) after completion of therapy with ponutunumumab in combination with chlorambucil and persisted for 6 months.

Recovery of the number of B-cells occurred within 12-18 months in 35% of patients in the absence of progression and in 13% of patients with progression of the disease.

Immunogenicity

Testing for the presence of antibodies to the drug (ATA) was carried out at various time points.
In 10 out of 146 patients who received the Gaziva В® drug, antibodies to the drug were detected 12 months after the completion of the last cycle of therapy. Patients showed no cases of anaphylaxis or hypersensitivity reactions associated with ATA, or a negative impact on the clinical response.
In 2 patients with indolent non-Hodgkin's lymphoma from the group of therapy with the drug GazivaВ® in combination with bendamustine and having positive results in the initial determination of human antibodies to human antibodies (ANAS - HumanAnti-HumanAntibodies), infusion reactions developed.
Education ANAS to the preparation Gaziva В® during or after its use was not observed.
The results of the immunogenicity assay largely depend on various factors, the methodology of the assay, the concentration of the Gaziva В® / antibodies in serum, the concomitant medications and the nature of the underlying disease.
Thus, comparing the frequency of detection of antibodies to the Gaziva В® preparation and the frequency of detection of antibodies to other biological preparations may not be informative.
PHARMACOKINETICS

Suction

Obinutuzumab is administered iv.
Other ways of drug administration have not been studied. The calculated value of the median C max after infusion in cycle 6, day 1 in patients with chronic lymphocytic leukemia was 465.7 Ојg / ml, and the AUC value for the period of AUC (t) was 8961 Ојg / ml and in patients with indolent non-Hodgkin's lymphoma (INHL ) - 539.3 Ојg / ml and 10,956 Ојg / dl, respectively.
Distribution

After IV introduction, the volume of distribution
in the central chamber (V c ) is 2.72 liters and is approximately equal to the volume of serum. The values ​​of Vc and Vd of ponutunuzumab in the equilibrium state (V ss ) indicate that the distribution occurs only in plasma and extracellular fluid.
Metabolism

There have not been any separate studies of the metabolism of pontumatusum.
Like other antibodies, ponutuzumab is mainly exposed to catabolism.
Excretion

The prevalence of prenutuzumab in patients with CLL was approximately 0.11 l / day and in patients with INHL approximately 0.08 l / day with a median T 1/2 of26.4 days with CLL and 36.8 days for INHL.

The removal of ponunutuzumab is characterized by both linear clearance and nonlinear clearance.
In the initial period of treatment, the time-dependent nonlinear clearance is the main, but with the continuation of therapy, its contribution gradually decreases, and the linear path becomes dominant. This indicates a target-mediated distribution of the drug (OMPR), in which an excess of CD20 + B cells determines a drastic decrease in the concentration of prenutuzumab in serum. When most of the CD20 + B cells are associated with ponubutuzumab, OMRP has minimal effect on the pharmacokinetics of the drug.
Pharmacokinetics in specific patient groups

According to the population analysis, the clearance in the equilibrium state and V d in men are higher by 18% and 19%, respectively.
However, differences in the exposure of exogenous tonsillum in men and women are insignificant (for CLL medians AUC and C max in the 6 cycle were 11 282 Ојg / d and 578.9 Ојg / ml in women and 8451 Ојg / dl and 432.5 Ојg / ml for men, respectively, with median AUC and C max , 1372 Ојg / ml and 635.7 Ојg / ml for women and 9769 Ојg / ml for mice and 481.3 Ојg / ml for men, respectively), dose adjustment depending on sex is not required.
There were no significant differences in the pharmacokinetics of pontinumusumab in patients <65 years of age, 65 to 75 years of age, and in patients> 75 years of age.

The values ​​of the pharmacokinetic parameters of profinutuzumab in patients with mild (KK 50-89 ml / min) and mean (KK 30-49 ml / min) degree of renal failure are similar to those in patients with normal renal function (KK-90 ml / min).
Data on pharmacokinetics in patients with severe renal insufficiency (QC 15-29 ml / min) are limited, so it is not possible to give special instructions for dosing.
Special studies of pharmacokinetics in patients with impaired liver function were not performed.

Premedication and prevention of tumor lysis syndrome (SLO)

Patients with high tumor burden and / or high lymphocyte count in peripheral blood (> 25 Г— 10 9 / L) and / or renal insufficiency (CC <70 mL / min) require the prophylaxis of OA because they are at risk of developing VL.

Prevention includes adequate hydration and the administration of hypo-uricemic drugs (eg, allopurinol or other alternative drugs) prior to infusion of the Gaziva В®preparation in accordance with standard practice.
In the event that the patient's condition still meets the criteria of the OA, before each subsequent infusion it is also necessary to carry out prophylaxis of the OA.
Premedication and prevention of infusion reactions

Information on conducting premedication to reduce the risk of developing infusion reactions is given in Table 1. Premedication of GCS is recommended for patients with follicular lymphoma (PL) and is mandatory for patients with chronic lymphocytic leukemia (CLL) with the first infusion.
Premedication with subsequent infusions and other types of premedication should be carried out as described below.
Given that one of the manifestations of infusion reactions may be a decrease in blood pressure, consideration should be given to the possibility of suspending treatment with antihypertensive agents for 12 hours before each infusion during the infusion and within 1 hour after its termination.

Chronic lymphocytic leukemia
The overall incidence of thrombocytopenia during therapy with the drug Gaziva В®in combination with chlorambucil was 15.4%, while the acute thrombocytopenia that develops within 24 h after infusion, there was 4% of patients. Bleeding rate was 8%. About fatal cases of bleeding was reported only in the first cycle of therapy in 1% of patients. The causal relationship between the development of thrombocytopenia and bleeding has not been established.

incidence of thrombocytopenia in a group of drug therapy Gaziva В® and bendamustine was lower (15%) compared to the group treated only bendamustine (24%). Frequency hemorrhagic events (11% in the drug therapy Gaziva В® and bendamustine, 10% in the group of bendamustine) and hemorrhagic phenomena 3-5 severity (5% in a group of drug therapy GazivaВ® and bendamustine, 3% in the bendamustine) was comparable in both treatment groups, of deaths have been reported.
