    L.01.X.C   Monoclonal antibodies

    L.01.X.C.03   Trastuzumab

    Pharmacodynamics:

    Trastuzumab is a recombinant DNA-derived humanized monoclonal antibody that selectively interacts with the extracellular domain of the human type 2 epidermal growth factor receptor (HER2). These antibodies are IgG1, consisting of human regions (constant sections of heavy chains) and determining the complementarity of mouse regions of the antibody p185 HER2 to HER2.

    Proto-oncogene HER2 or c-yegB2 encodes a transmembrane receptor-like protein with a molecular weight of 185 kDa, which is structurally similar to other members of the epidermal growth factor receptor family. Hyperexpression HER2 is found in the tissue of primary breast cancer (breast cancer) in 15-20% of patients.

    Total frequency of detection HER2- positive status in the tissue of advanced gastric cancer in screening patients was 15% IHC (immunohistochemical reaction method) 3+ and IGH2 + / FISH+ (hybridization method in situ) or 22.1% when applying the broader definition of IHC + or FISH+. Amplification of the gene HER2 leads to overexpression of the protein HER2 on the membrane of tumor cells, which in turn causes a constant activation of the receptor HER2. The extracellular domain of the receptor (ECD, p 105) may fall into the bloodstream and be detected in serum samples. Studies show that patients with breast cancer who are noted for amplification or overexpression HER2 in tumor tissue, have a less survival without symptoms of disease compared to patients without amplification or overexpression HER2 in the tumor tissue.

    Trastuzumab blocks proliferation of human tumor cells with overexpression HER2 in vivo and in vitro. In vitro the antibody-dependent cellular cytotoxicity of trastuzumab is predominantly directed to tumor cells with overexpression HER2.

    Immunogenicity

    With neoadjuvant-adjuvant therapy, 7.0% of patients who received the drug intravenously appeared antibodies to trastuzumab (regardless of the presence of antibodies initially).

    The clinical significance of these antibodies is unknown. However, these antibodies do not appear to have a negative effect on pharmacokinetics, efficacy (defined as a complete pathological response), or the safety of trastuzumab when administered intravenously.

    Data on immunogenicity in the use of Herceptin® for the treatment of stomach cancer are absent.

    Pharmacokinetics:

    The pharmacokinetics of trastuzumab have been studied in patients with metastatic breast cancer (MMR) and early stages of breast cancer, as well as in patients with advanced stomach cancer. Special studies on the study of inter-drug interaction were not conducted.

    Mammary cancer

    When the drug was administered in the form of short intravenous infusions at a dose of 10, 50, 100, 250 and 500 mg once a week, the pharmacokinetics was nonlinear.With increasing dose, the clearance of the drug decreased.

    Half-life

    The half-life is 28-38 days, therefore, the withdrawal period after discontinuation of the drug is up to 27 weeks (190 days or 5 half-lives).

    Pharmacokinetics of trastuzumab against the background of the equilibrium state

    The equilibrium state should be reached in about 27 weeks. Using the population pharmacokinetic method (two-chamber model, model-dependent analysis) of the data of Phase I, Phase II and Phase III studies for metastatic breast cancer, the median of the expected area under the concentration-time curve (AUC) in the equilibrium state after 3 weeks was 1677 mg * day / l after the administration of 3 doses (2 mg / kg) weekly and 1793 mg * day / l after 3 weeks at a dose of 6 mg / kg. Calculated medians of maximum concentration (CmOh) were 104 mg / l and 189 mg / l, and the minimum concentration (Cmin) - 64.9 mg / l and 47.3 mg / l, respectively. Average Cmin in the equilibrium state on day 21 of cycle 18 (the last cycle with a duration of treatment of 1 year) was 68.9 μg / ml, and CmOh- 225 μg / ml in patients with early breast cancer who received trastuzumab in a loading dose of 8 mg / kg, then in a maintenance dose of 6 mg / kg, after 3 weeks, and were comparable to those in patients with MMR.

    Clearance

    The typical clearance of trastuzumab (for a patient with a body weight of 68 kg) was 0.241 l / day.

    Volume of distribution

    In all clinical studies, the volume of distribution in the central chamber (Vc) was 3.02 liters, in the peripheral (Vp) - 2.68 l for a typical patient.

    Circulating extracellular domain HER2- receptor ("sluschivayuschiesya" with the cell antigen)

    In the serum of some patients with breast cancer and HER2 Overexpression revealed circulating extracellular domain HER2- receptor ("sluschivayuschiesya" with the cell antigen). In 64% of patients studied in baseline serum samples detected "exfoliated" cells with antigen at a concentration reaches 1880 ng / ml (median 11 ng / ml). Patients who had a high concentration of "slipping" from the cell antigen, probably could have a lower Cmin. However, in most patients with an elevated "sluschivayuschegosya" with the cell antigen when the drug was administered weekly, the target concentration of trastuzumab in the serum was reached by week 6. There was no significant relationship between the baseline level of the antigen "slipping" from the cell and the clinical response.

    Common stomach cancer

    Pharmacokinetics of trastuzumab against the background of the equilibrium state

    To evaluate the pharmacokinetics of trastuzumab against a background of the equilibrium state, in patients with advanced gastric cancer after administration of trastuzumab at a loading dose of 8 mg / kg, followed by 6 mg / kg every 3 weeks, a non-linear two-compartment population pharmacokinetic method was used using Phase III data.

    The observed levels of serum trastuzumab concentrations were lower, thus, it was found that the overall clearance of the drug in patients with advanced stomach cancer is higher than in patients with breast cancer who receive trastuzumab in the same dose. The reason for this is unknown.

    At high concentrations, the overall clearance is primarily linear, and the elimination half-life is about 26 days.

    The median of the expected indicator AUC (in the equilibrium state during the 3-week period) is 1213 mg * day / L, the median CmOh in the equilibrium state - 132 mg / l, median Cmin. - 27.6 mg / l.

    Data on the level of the circulating extracellular domain HER2- receptor ("sluschivayuschiesya" with cells antigen) in the serum of patients with stomach cancer are absent.

    Pharmacokinetics in specific patient groups

    Individual pharmacokinetic studies in elderly patients and patients with renal or hepatic insufficiency have not been performed.

    Elderly age

    Age does not affect the distribution of trastuzumab.

    Herceptin® is not compatible with 5% dextrose solution because of the possibility of protein aggregation.

    Herceptin should not be mixed or diluted with other medications.

    Solution Herceptin ® is compatible with infusion bags made of polyvinyl chloride, polyethylene and polypropylene.

    Preparation of the solution

    Preparation of the drug for administration should be carried out under aseptic conditions. Instructions for preparing a solution

    The contents of the 150 mg Herceptin® vial are dissolved in 7.2 ml sterile water for injection.

    During the dissolution should be carefully treated with the drug. When dissolving, excessive foaming should be avoided, the latter may make it difficult to obtain the desired dose of the drug from the vial.

    - With a sterile syringe, slowly inject 7.2 ml of sterile water for injection into a bottle of 150 mg of Herceptin ®, directing the liquid stream directly to the lyophilizate.

    - For dissolution, gently shake the bottle with rotational movements. Do not shake!

    When the preparation is dissolved, a small amount of foam is often formed. To avoid this, allow the solution to stand for about 5 minutes. The prepared solution should be clear and colorless or have a pale yellow color.

    Storage conditions of the prepared solution A bottle with 150 mg of the drug is used only once.

    Herceptin® solution is physically and chemically stable over the course of 24 hours at a temperature of 2-8 ° C after dissolving with sterile water for injections.Do not freeze!

    Preparation of a solution for infusion should be carried out immediately after dissolving the lyophilizate. In exceptional cases, the solution after dissolution of the lyophilisate can be stored for no more than 24 hours at a temperature of 2-8 ° C if the solution of the lyophilizate passes in controlled and validated aseptic conditions. At the same time for the storage conditions (storage rules and duration), the specialist who dissolves lyophilizate answers.

    Instructions for preparing a solution for infusion Determine the volume of the solution:

    - required for administration of a loading dose of trastuzumab of 4 mg / kg body weight or a maintenance dose of 2 mg / kg is determined by the following formula:

    body mass (kg) x dose (4 mg / kg loading or 2 mg / kg maintenance)

    Scope (ml) = -------------------------------------------------------------------------------------------------

    21 (mg / ml, concentration of the prepared solution)

    - necessary for the administration of a loading dose of trastuzumab equal to 8 mg / kg of body weight or a maintenance dose of 6 mg / kg every 3 weeks is determined by the following formula:

    body mass (kg) x dose (8 mg / kg loading or 6 mg / kg maintenance)

    Scope (ml) = ------------------------------------------------------------------------------------------------------

    21 (mg / ml, concentration of the prepared solution)

    From the vial with dissolved lyophilizate should be dialed the appropriate volume and enter it into the infusion bag with 250 ml of 0.9% sodium chloride solution. Then the infusion bag should be turned gently to mix the solution, avoiding foaming. Before administration, the solution should be checked (visually) for the absence of mechanical impurities and discoloration. Solution for infusion is administered immediately after its preparation.

    In exceptional cases, the prepared infusion solution can be stored for no more than 24 hours at a temperature of 2-8 ° C, if dissolution of the lyophilizate and the preparation of the infusion solution takes place under controlled and validated aseptic conditions. At the same time for the storage conditions (storage rules and duration) is the specialist who prepared the solution.

    Instructions for disposal of unused product or expired

    The presence of the drug in the environment should be minimized. Do not dispose of the product with sewage or with household waste. If possible, it is necessary to use special systems for the disposal of medicinal products.

    Standard dosing regimen

    During each administration of trastuzumab, the patient should be carefully monitored for chills, fever, and other infusion reactions (within 6 hours after the start of the first infusion and within 2 hours after the start of subsequent infusions). An emergency kit should be available, and an infusion should be performed by a medical specialist experienced in the treatment of anaphylaxis.

    In the case of the appearance of infusion reactions, the infusion is interrupted. After the disappearance of symptoms of infusion reactions of mild and moderate severity according to NCI-CTC (the general criteria for the toxicity of the National Cancer Institute in the United States) may be the resumption of infusion. In the case of development of severe and life-threatening infusion reactions consideration should be given to discontinuing further therapy with Herceptin®.

    In the future, monotherapy with Herceptin® continued according to the weekly schedule after application in combination with paclitaxel or as administered 3 weeks after use in combination with docetaxel. The total duration of therapy with Herceptin® from the first administration was 1 year, regardless of the number of doses received or missed. If paclitaxel or docetaxel and the drug Herceptin® should have been administered on the same day, then paclitaxel or docetaxel was introduced first.

    The use in combination with docetaxel and carboplatinum

    Docetaxel / Carboplatin (every 3 weeks for 6 cycles, starting from day 2 of the first cycle, then on day 1 in each subsequent cycle):

    Metastatic and early stages of breast cancer and common stomach cancer

    Duration of therapy

    Treatment with Herceptin® in patients with metastatic breast cancer or advanced gastric cancer is carried out before the disease progresses. Patients with early stages of breast cancer should receive therapy with Herceptin® for 1 year or until the recurrence of the disease (depending on what happens more quickly). Treatment with Herceptin® in patients with early stages of breast cancer over one year is not recommended.

    Skipping in the planned introduction

    If the admission in the planned administration of trastuzumab is 7 days or less, the drug should be administered as soon as possible in the usual maintenance dose (weekly schedule:

    - mg / kg of body weight; mode every 3 weeks: 6 mg / kg body weight), without waiting for the next scheduled administration. Next, administer the drug in a maintenance dose (weekly regimen: 2 mg / kg body weight, every 3 weeks: 6 mg / kg body weight) according to the schedule.

    If the break in the introduction of the drug is more than 7 days, you must re-enter the loading dose of trastuzumab (weekly regimen: 4 mg / kg body weight, regimen every

    - weeks: 8 mg / kg body weight), as a 90-minute intravenous drip infusion. Then continue the administration of the drug in a maintenance dose (weekly regimen: 2 mg / kg body weight, every 3 weeks: 6 mg / kg body weight).

    Correction of dose

    In the period of origin reversible myelosuppression, a course of therapy with Herceptin® can be continued after a reduction in the dose of chemotherapy or its temporary withdrawal (according to the relevant recommendations in the instructions for the use of paclitaxel, docetaxel or an aromatase inhibitor), subject to careful monitoring of the complications caused by neutropenia.

    When decrease in the left ventricular ejection fraction (LVEF) by> 10 units from the original AND below the value of 50% treatment should be suspended. A reassessment of LVEF should be performed after approximately 3 weeks. If there is no improvement in LVEF or its further decrease, or if symptoms of chronic heart failure (CHF) appear, it is necessary to consider stopping Herceptin treatment unless the benefit for a particular patient exceeds the risks. All these patients should be referred to a cardiologist for a survey and be monitored.

    Below you will find information on individual adverse reactions. Heart Dysfunction

    Chronic heart failure II-IV functional class for NYHA (classification of the New York Association of Cardiologists) is a frequent undesirable reaction with the use of Herceptin ® and was associated with a fatal outcome. The following signs and symptoms of cardiac dysfunction were observed in patients treated with Herceptin®: dyspnea, orthopnea, increased cough, pulmonary edema, gallop rhythm, or a decrease in the left ventricular ejection fraction.In 3 basic clinical trials using trastuzumab in combination with adjuvant chemotherapy, the incidence of cardiac dysfunction of 3/4 degree (namely, symptomatic chronic heart failure) did not differ from that in patients receiving chemotherapy alone (ie, without Herceptin®), and in patients receiving taxanes and Herceptin® consistently (0.3-0.4%). The frequency was greatest in patients receiving Herceptin® together with taxanes (2.0%). Experience with Herceptin® in combination with low-dose anthracycline regimens in neoadjuvant therapy is limited.

    When using Herceptin ® for one year after the completion of adjuvant chemotherapy, heart failure III-IV functional class for NYHA was observed in 0.6% of patients with median follow-up of 12 months and in 0.89% of patients with median follow-up of 8 years. The incidence of mild symptomatic and asymptomatic left ventricular dysfunction was 6.35%. Severe CHF was reversible in 70% of cases (reversibility was determined by at least two consecutive increases in LVEF> 50% after the event).The mild symptomatic and asymptomatic left ventricular dysfunction was reversible in 83.1% of cases. Approximately 10% of the phenomena with cardiac dysfunction arose after the completion of Hercease therapytin®.

    In basic clinical studies with metastatic breast cancer, the incidence of cardiac dysfunction with intravenous administration of Herceptin® in combination with paclitaxel ranged from 9% to 12% compared to 1% -4% for paclitaxel monotherapy. For monotherapy with Herceptin® frequency was 6%-9%. The highest incidence of cardiac dysfunction was observed in patients receiving Herceptin® simultaneously with anthracyclines / cyclophosphamide (27%), which is significantly higher than for anthracycline / cyclophosphamide therapy (7% -10%). In a prospective cardiac monitoring study, the incidence of symptomatic CHF was 2.2% in patients receiving Herceptin® and docetaxel, compared with 0% in patients who received monotherapy with docetaxel. In the majority of patients (79%) with cardiac dysfunction, there was an improvement after standard CHF treatment.

    Infusion reactions and hypersensitivity reactions

    It is estimated that about 40% of patients receiving Herceptin ® experience infusion reactions in one form or another. However, most infusion reactions are mild and moderate in severity (according to NCI-CTC) and tend to occur at the beginning of treatment, i.e. during the 1st, 2nd and 3rd infusions, with subsequent injections occur less frequently. Reactions include the following symptoms: chills, fever, shortness of breath, arterial hypotension, wheezing in the lungs, bronchospasm, tachycardia, decreased oxygen saturation of hemoglobin, respiratory distress syndrome, rash, nausea, vomiting and headache.

    The frequency of infusion reactions of all degrees of severity varies and depends on the indication, methodology of information collection, and also whether Herceptin® was administered together with chemotherapy or applied in monotherapy.

    Severe anaphylactic reactions requiring immediate additional medical interventions are most likely to occur during the first or second infusion of Herceptin®, such reactions are associated with a fatal outcome.In some cases, anaphylactoid reactions were observed.

    Hematological toxicity

    Very often there was febrile neutropenia. Undesirable reactions that occur frequently include anemia, leukopenia, thrombocytopenia and neutropenia. The frequency of hypoprothrombinemia is unknown. The risk of neutropenia may be slightly higher with trastuzumab in combination with docetaxel after therapy with anthracycline-based drugs.

    Disorders from the side of the lungs

    With the use of the drug Herceptin ® associated with serious adverse effects from the lungs (including fatal outcome). These reactions include, but are not limited to: pulmonary infiltrates, acute respiratory distress syndrome, pneumonia, pneumonitis, pleural effusion, acute pulmonary edema, and respiratory failure.

    Overdose:In clinical studies, no overdose of the drug was observed. The administration of Herceptin® in single doses greater than 10 mg / kg has not been studied. Herceptin® in doses <10 mg / kg was tolerated well.
    Interaction:

    Special studies of drug interactions with Herceptin ® have not been conducted.

    In clinical trials, clinically relevant interactions with concomitantly used drugs (including doxorubicin, paclitaxel, docetaxel, capecitabine or cisplatin) was not observed.

    The effect of trastuzumab on the pharmacokinetics of other antitumour drugs Pharmacokinetic data obtained in women with HER2- positive metastatic breast cancer, it is suggested that exposure to paclitaxel and doxorubicin and their major metabolites (6-alpha-hydroxypaclitaxel and doxorubicinol) does not change in the presence of trastuzumab when administered at a loading dose of 8 mg / kg or 4 mg / kg in/at), and then in a maintenance dose (6 mg / kg every 3 weeks or 2 mg / kg every week in/at). Nevertheless, trastuzumab can increase the overall exposure of one of the metabolites of doxorubicin (7-deoxy-13-dihydrocoxorubicinone). The biological activity of this metabolite and the clinical significance of increasing its exposure are unknown. The data obtained in the study of the use of trastuzumab (4 mg / kg in loading dose and 2 mg / kg once a week, iv, in the supporting) and docetaxel (60 mg / m2) in Japanese patients with HER2- positive metastatic breast cancer suggest that simultaneous administration of trastuzumab does not affect the pharmacokinetics of a single-dose docetaxel.

    The results of the study of the pharmacokinetics of capecitabine and cisplatin when used in combination with or without trastuzumab in Japanese male and female patients with advanced stomach cancer suggest that the exposure biologically metabolites of capecitabine (for example, fluorouracil) did not change with simultaneous use of cisplatin or cisplatin and trastuzumab. However, higher concentrations of capecitabine and a longer half-life with trastuzumab have been reported. The data also indicate that the pharmacokinetics of cisplatin did not change with the simultaneous use of capecitabine or capecitabine in combination with trastuzumab.

    Effect of antitumor drugs on the pharmacokinetics of trastuzumab

    When comparing simulated serum concentrations of trastuzumab with monotherapy (at a loading dose of 4 mg / kg and supporting 2 mg / kg every week, iv) and trastuzumab concentrations when used in combination with docetaxel in Japanese patients with HER2- positive metastatic breast cancer showed no evidence of an effect of docetaxel on the pharmacokinetics of trastuzumab. Comparison of pharmacokinetic parameters in patients with HER2- positive metastatic breast cancer with the use of Herceptin ® concurrently with paclitaxel and with the use of Herceptin ® as a monotherapy shows that the individual and average values ​​of the minimum serum concentration of the Herceptin ® drug varied both within the same group and between groups, however, there was no obvious the effect of simultaneous administration of paclitaxel on the pharmacokinetics of trastuzumab was not observed.

    Co-administration with anastrozole does not affect the pharmacokinetics of trastuzumab. Herceptin® is not compatible with a 5% dextrose solution because of the possibility of protein aggregation. Herceptin® can not be mixed or dissolved with other medications.

    Signs of incompatibility between the solution of Herceptin ® and infusion packets made of polyvinyl chloride, polyethylene or polypropylene were not observed.

    Special instructions:
    In the patient's medical records, the trade name of the drug should be indicated. Replacement of the drug with any other biological medicinal product requires agreement with the attending physician.
    HER2 testing should be conducted in a specialized laboratory that can provide quality control testing procedures.
    Herceptin® should be used in patients with metastatic breast cancer or early breast cancer only if there is a tumor overexpression of HER2, determined by the method of immunohistochemical reaction (IHC), or amplification of the gene HER2, determined by the hybridization method in situ (FISH or CISH). Accurate and validated methods should be used.

    Herceptin® should be used in patients with metastatic stomach cancer only in the presence of tumor overexpression HER2, determined by the IHC method as IGX2 + and confirmed by the results SISH or FISH, or IGHZ +. Accurate and validated methods should be used.

    Currently, there are no data from clinical studies on patients who received Herceptin® repeatedly after use in adjuvant therapy.

    Heart Dysfunction

    General instructions

    Patients receiving Herceptin® as a monotherapy or in combination with paclitaxel or docetaxel, especially after chemotherapy involving anthracyclines (doxorubicin or epirubicin), have an increased risk of developing chronic heart failure (CHF) (II-IV functional class for NYHA) or asymptomatic cardiac dysfunction. The severity of these phenomena can vary from medium to severe. These phenomena can lead to death. In addition, care should be taken in the treatment of patients with high cardiovascular risk, for example, in elderly patients with hypertension, documented coronary heart disease, chronic heart failure, left ventricular ejection fraction (LVEF) <55%.

    Patients who are scheduled to administer Herceptin®, especially those that previously received anthracycline-based drugs and cyclophosphamide, must first undergo a thorough cardiological examination, including a history, physical examination, electrocardiography (ECG), echocardiography and / or radio isotope ventriculography (MUGA) or magnetic resonance imaging (MRI).Monitoring can identify patients with cardiac dysfunction. The initial cardiac examination should be repeated every 3 months during therapy and every 6 months after it is completed within 24 months of the administration of the last dose of the drug.

    Before starting treatment with Herceptin ®, you must carefully compare the possible benefits and risks of its use.

    Since the half-life of trastuzumab is about 28-38 days, the drug can be in the blood up to 27 weeks after completion of therapy. Patients who receive anthracyclines after completion of treatment with Herceptin ® may increase the risk of heart dysfunction. Where possible, physicians should avoid the appointment of anthracycline-based chemotherapy within 27 weeks after completion of therapy with Herceptin®. With the use of anthracycline drugs, careful monitoring of heart function should be carried out.

    It should be assessed the need for a standard cardiac examination in patients with suspected cardiovascular disease.All patients should monitor cardiac function during treatment (for example, every 12 weeks). As a result of monitoring, it is possible to identify patients who have developed cardiac dysfunction.

    In patients with asymptomatic cardiac dysfunction, it may be useful to monitor more frequently (for example, every 6-8 weeks). With prolonged worsening of left ventricular function, which is not manifested symptomatically, it is advisable to consider the question of drug cancellation if the clinical benefit from its use is absent.

    The safety of the continuation or resumption of therapy with Herceptin® in patients who developed a violation of the function of the heart has not been studied.

    If the left ventricular ejection fraction (LVEF) is reduced by> 10 units from the original AND below the value of 50%, treatment should be suspended. A reassessment of LVEF should be performed after approximately 3 weeks. If there is no improvement in LVEF or its further decline, or if symptoms of chronic heart failure (CHF) appear, consideration should be given to discontinuing Herceptin® treatment, unless the benefit for a particular patient is greater than the risk.All these patients should be referred to a cardiologist for a survey and be monitored.

    If symptomatic heart failure develops with the Herceptin ® therapy, appropriate standard medical therapy for CHF should be performed.

    The majority of patients with heart failure or asymptomatic cardiac dysfunction in basic studies observed improvement on the background of the standard drug therapy CHF: angiotensin converting enzyme inhibitors or angiotensin receptor blockers and beta-blockers. In the presence of clinical use of the drug Herceptin® majority of patients with adverse reactions on the part of the heart continued therapy without causing clinically significant additional reactions from the heart.

    Metastatic breast cancer

    Do not use the drug Herceptin® together in combination with an anthracycline to treat metastatic breast cancer.

    The risk of cardiac dysfunction in patients with metastatic breast cancer increased with the previous treatment with anthracyclines,but it is lower in comparison with that with the simultaneous use of anthracyclines and the Herceptin® preparation.

    Early stages of breast cancer

    Patients with early breast cancer should undergo a cardiac examination before the start of treatment, every 3 months during therapy and every 6 months after the end of treatment, within 24 months of the administration of the last dose of the drug. Longer monitoring is recommended after treatment with Herceptin® in combination with anthracyclines at a frequency of 1x per year for 5 years after the last dose of Herceptin®, or further if there is a continuous decrease in LVEF.

    Treatment with Herceptin is not recommended for patients in early stages of breast cancer (adjuvant and neoadjuvant therapy) with: a history of myocardial infarction; angina pectoris requiring treatment; CHF (II-IV functional class for NYHA) in the anamnesis or at present; LVEF is below 55%; other cardiomyopathies; arrhythmias requiring treatment; clinically significant heart defects; poorly controlled hypertension, with the exception of arterial hypertension,amenable to standard drug therapy; hemodynamically significant pericardial effusion, as the efficacy and safety of the drug in such patients have not been studied.

    Adjuvant therapy

    It is not recommended to use Herceptin ® together in combination with anthracyclines in adjuvant therapy. In patients with early-stage breast cancer who received Herceptin after anthracycline-based chemotherapy was observed increase in the incidence of symptomatic and asymptomatic adverse events from the heart compared with those who received chemotherapy with docetaxel and carboplatin (regimes that do not contain drugs anthracyclines). The difference was greater in cases of combined use of Herceptin® and taxanes than with sequential use.

    Regardless of the regime used, most symptomatic cardiac events occurred in the first 18 months of treatment. In one of the 3 basic research (with a median follow-up period 5.5 years) showed sustained increase in the cumulative incidence of symptomatic cardiac events or phenomena associated with decreased left ventricular ejection fraction: 2.37% in patients treated with Gerclinker® together with taxanes after anthracycline therapy, compared with 1% of patients in the comparison groups (in the anthracycline and cyclophosphamide, further taxanes, and in the therapy group with taxanes, carboplatin and Herceptin®). Identified risk factors for the development of adverse cardiac events with adjuvant therapy with Herceptin® are: age> 50 years, low baseline LVEF (<55%) before and after initiation of paclitaxel treatment, reduction of LVEF by 10-15 units, prior or concomitant administration of antihypertensive drugs. Risk of impaired cardiac function in patients receiving Herceptin® after completion of adjuvant chemotherapy, was associated with a higher total dose of anthracyclines before starting treatment with Herceptin® and with a body mass index (BMI)> 25 kg / m2.

    Neoadjuvant-adjuvant therapy

    For patients with early stages of breast cancer who may be prescribed neoadjuvant-adjuvant therapy, the use of Herceptin® with anthracyclines is recommended only if they have not previously received chemotherapy and only

    when using low-dose regimens of anthracycline therapy (maximum sum2Marble dose of doxorubicin 180 mg / m2 or epirubicin 360 mg / m).

    In patients who received a full course of low-dose anthracyclines and Herceptin® in the neoadjuvant therapy, additional cytotoxic chemotherapy is not recommended after surgical intervention. In all other cases, the decision on the need for additional cytotoxic chemotherapy is taken on the basis of individual factors. The experience with trastuzumab in conjunction with low-dose regimens for anthracycline therapy is limited to two studies. When using Herceptin® together with neoadjuvant chemotherapy, which included three to four cycles of neoadjuvant therapy with anthracyclines (total dose of doxorubicin 180 mg / m2 or epirubicin 300 mg / m2), the incidence of symptomatic cardiac dysfunction was low (1.7%). Clinical experience in patients older than 65 years is limited. Infusion reactions and hypersensitivity reactions

    When the drug Herceptin® there were serious infusion unwanted reactions: dyspnea, arterial hypotension, wheezing in the lungs, arterial hypertension, bronchospasm, supraventricular tachyarrhythmia, decreased oxygen saturation of hemoglobin, anaphylaxis, respiratory distress syndrome, urticaria and angioedema. Premedication can be used to reduce the risk of these phenomena. Most of these reactions occurred during infusion or within 2.5 hours from the onset of the first administration. If an infusion reaction occurs, the injection should be stopped and the patient carefully monitored until all symptoms are eliminated. To stop these symptoms, analgesics / antipyretics, such as paracetamol, or antihistamines, such as diphenhydramine. Most patients, after resolving the symptoms of infusion reactions, were able to continue therapy with Herceptin®.

    Effective therapy of serious reactions consists in the use of beta-adrenostimulators, glucocorticosteroids, oxygen inhalation.

    In case of development of severe and life-threatening infusion reactions, consideration should be given to stopping further therapyHerceptin®. In rare cases, these reactions were associated with a fatal outcome. The risk of developing lethal infusion reactions is higher in patients with dyspnea at rest caused by lung metastases or concomitant diseases, so such patients should not be treated with Herceptin®.

    There have been reported cases in which, after initial improvement, there was a worsening of the condition, as well as cases with delayed rapid deterioration of the condition. Lethal outcome occurred within hours or one week after infusion. In a very

    In rare cases, patients developed symptoms of infusion reactions or pulmonary

    symptoms (after more than 6 hours after the onset of Herceptin® administration, patients should be warned about the possible delayed development of these symptoms and the need for immediate contact with the doctor if they arise.

    Disorders from the side of the lungs

    With the use of Herceptin ® in the postgravitational period, severe lung events were recorded, which were sometimes accompanied by a fatal outcome.In addition, cases of interstitial lung disease (IBL) have been reported, including pulmonary infiltrates, acute respiratory distress syndrome, pneumonia, pneumonitis, pleural effusions, acute pulmonary edema, and respiratory failure. Risk factors associated with IBL include: previous or concomitant therapy with other antitumor drugs that are known to be associated with IBL (taxanes, gemcitabine, vinorelbine and radiation therapy). These phenomena can occur as manifestations of infusion reactions, and deferred. The risk of severe reactions from the lungs is higher in patients with metastatic lung involvement, concomitant diseases accompanied by dyspnea at rest. Therefore, such patients should not

    receive Herceptin® . Care should be taken, especially in patients receiving concomitant taxane therapy, because of the development of pneumonitis. Sterile water for injection, used to dissolve the contents of the bottle with 150 mg of Herceptin ®, does not contain benzyl alcohol.
