Pharmacological action of
Pharmacodynamics of
Trastuzumab is a recombinant DNA-derived humanized monoclonal antibody that selectively interacts with the extracellular domain of human epidermal growth factor 2 receptors (HER2). These antibodies are IgG1 consisting of human regions (constant regions of heavy chains) and determining the complementarity of the murine regions of p185 HER2 anti-HER2 antibody.
The HER2 or c-erB2 proto-oncogen 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. Overexpression of HER2 is found in the tissue of primary breast cancer (BC) in 25-30% of patients and in the tissue of advanced gastric cancer in 6.8-42.6% of patients. Amplification of the HER2 gene leads to overexpression of the HER2 protein on the membrane of the tumor cells, which in turn causes constant activation of the HER2 receptor.
Studies show that patients with breast cancer who have amplified or overexpressed HER2 in the tumor tissue have less survival without evidence of disease than patients without amplification or overexpressed HER2 in the tumor tissue.
Trastuzumab blocks the proliferation of human tumor cells with overexpression of HER2 in vivo and in vitro. In vitro, antibody-dependent cellular cytotoxicity of trastuzumab is primarily directed to tumor cells with HER2 overexpression.
Immunogenicity
Trastuzumab antibodies were detected in one of 903 breast cancer patients who received the drug in monotherapy or in combination with chemotherapy, but did not have any allergies to Herceptin ®.
There is no data on the immunogenicity of Herceptin ® for gastric cancer.
Pharmacokinetics
The pharmacokinetics of trastuzumab has been studied in patients with metastatic breast cancer and early stages of breast cancer, as well as in patients with advanced gastric cancer. Special studies on the study of drug interactions have not been conducted.
Breast cancer
With the introduction of the drug in the form of short iv infusions at a dose of 10, 50, 100, 250 and 500 mg once a week, the pharmacokinetics was non-linear. With increasing doses, the clearance of the drug decreased.
Elimination half-life (T1 / 2)
T1 / 2 is 28-38 days, therefore, the elimination period after drug withdrawal is up to 27 weeks (190 days or 5 elimination half-lives).
Pharmacokinetics of trastuzumab against equilibrium.
An equilibrium should be reached in about 25 weeks. When using the population pharmacokinetic method (two-chamber model, model-dependent analysis) for evaluating phase I studies, Phase II and phase III with metastatic breast cancer, the median of the expected AUC in equilibrium after 3 weeks was 1677 mg Day / l after 3 doses (2 mg / kg) weekly and 1793 mg day / l when administered after 3 weeks at a dose of 6 mg / kg The calculated medians of Cmax were 104 mg / L and 189 mg / L, and Cmin – 64.9 mg / L and 47.3 mg / L, respectively. When using a model-independent or non-chamber analysis method (non-compartmental analysis, NCA), the average Cmin in equilibrium by cycle 13 (week 37) was 63 mg / L in patients with early breast cancer who received trastuzumab at a loading dose of 8 mg / kg , then in the supporting 6 mg / kg, after 3 weeks, and was comparable to that in patients with breast cancer receiving trastuzumab weekly.
Clearance
The typical clearance of trastuzumab (for a patient weighing 68 kg) was 0.241 l / day.
Distribution volume
In all clinical trials, the distribution volume in the central chamber (Vc) was 3.02 L and in the peripheral (Vp) 2.68 L for a typical patient.
The circulating extracellular domain of the HER2 receptor (cell-desorbing antigen)
In the blood serum of some patients with breast cancer and HER2 hyperexpression, a circulating extracellular domain of the HER2 receptor (cell-descending antigen) was found. In 64% of the examined patients, the antigen peeling from the cell was detected in the initial serum samples at a concentration reaching 1880 ng / ml (median 11 ng / ml). Patients with a high concentration of antigen desquamation from the cell probably could have a lower Cmin. However, in most patients with an increased level of antigen desquamating from the cell with the introduction of the drug, the target serum trastuzumab concentration was reached by week 6. There was no significant relationship between the initial level of antigen peeling from the cell and the clinical response.
Common gastric cancer
Pharmacokinetics of trastuzumab against equilibrium To evaluate the pharmacokinetics of trastuzumab against equilibrium in patients with advanced gastric cancer after administration of trastuzumab at a loading dose of 8 mg / kg, followed by the administration of 6 mg / kg every 3 weeks, a non-linear two-dimensional pharmacokinetic method using data from a phase III study.
The observed serum trastuzumab concentration levels were lower, thus it was found that the total clearance of the drug in patients with advanced gastric cancer is higher than in patients with breast cancer receiving trastuzumab in the same dose. The reason for this is unknown.
At high concentrations, the overall clearance is mostly linear, and T1 / 2 is about 26 days.
The median of the estimated AUC (in equilibrium over a 3 week period) is 1213 mg day / l, the median Cmax in equilibrium is 132 mg / l, and the median Cmin is 27.6 mg / l.
There are no data on the level of the circulating extracellular domain of the HER2 receptor (cell-disengaging antigen) in the serum of patients with gastric cancer.
Pharmacokinetics in special patient groups
No separate pharmacokinetic studies have been performed in elderly patients or patients with renal or hepatic impairment. Age does not affect the distribution of trastuzumab.

Dosage and Administration
Testing for tumor expression of HER2 prior to treatment with Herceptin ® is mandatory.
Herceptin ® is administered only intravenously! It is impossible to administer the drug intravenously in a jet or bolus!
Herceptin ® is not compatible with 5% dextrose solution due to the possibility of protein aggregation. Herceptin ® should not be mixed or diluted with other drugs.
Herceptin ® solution is compatible with infusion bags made of polyvinyl chloride, polyethylene and polypropylene.
Preparation of
solution Preparation of the drug for administration should be carried out under aseptic conditions.
Instruction for the preparation of
concentrate The contents of the Herceptin ® vial are diluted in 20 ml of bacteriostatic water for injection, which is supplied with the preparation, containing 1.1% benzyl alcohol as an antimicrobial preservative. The result is a solution concentrate suitable for repeated use, containing 21 mg of trastuzumab in 1 ml and having a pH = 6.0.
During dissolution, the preparation should be carefully handled. When dissolving, excessive foaming should be avoided, the latter can make it difficult to set the right dose of the drug from the bottle.
Using a sterile syringe, slowly inject 20 ml of bacteriostatic water for injection into a 440 mg vial of Herceptin ®, directing a stream of liquid directly to the lyophilisate.
To dissolve, gently shake the vial with rotational movements. Do not shake!
When a drug is dissolved, a small amount of foam is often formed. To avoid this, let the solution stand for about 5 minutes. The prepared concentrate should be transparent and colorless or have a pale yellow color.
Herceptin ® solution concentrate prepared on bacteriostatic water for injection is stable for 28 days at a temperature of 2-8 ° C. The prepared concentrate contains a preservative and therefore can be used repeatedly. After 28 days, the unused concentrate residue should be discarded. Do not freeze!
As a solvent for Herceptin ® 440 mg, sterile water for injection (without preservative) is allowed. Other solvents should be avoided. If sterile water for injection is used as a solvent, the concentrate is physically and chemically stable only for 24 hours at a temperature of 2-8 ° C and should be discarded after this time. Do not freeze!
Instructions for preparing an infusion solution
Determine the volume of solution: required to administer a loading dose of trastuzumab equal to 4 mg / kg body weight, or a maintenance dose equal to 2 mg / kg, is determined by the following formula:
Volume (ml) = body weight (kg) – dose (4 mg / kg loading or 2 mg / kg maintenance) / 21 (mg / ml, concentration of the prepared solution)
necessary to administer a loading dose of trastuzumab equal to 8 mg / kg body weight, or a maintenance dose equal to 6 mg / kg every 3 weeks, determined by the following formulas :
Volume (ml) = body weight (kg) dose (8 mg / kg loading or 6 mg / kg maintenance) / 21 (mg / ml? concentration of the prepared solution).
From the vial with the prepared concentrate, dial 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 carefully turned over to mix the solution, avoiding foaming. Before administration, the solution should be checked (visually) for any mechanical impurities and discoloration. The 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 the concentrate was dissolved and the infusion solution was prepared under controlled and validated aseptic conditions. In this case, the storage conditions (storage rules and duration) are the responsibility of the specialist who prepared the solution.
Instructions for disposing of an unused or expired product
The release of a drug into the environment should be minimized. Do not dispose of the product with wastewater or with household waste. If possible, use special systems for the disposal of drugs.
Standard dosing regimen
During each administration of trastuzumab, the patient should be closely 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 the infusion should be done by a medical professional experienced in the treatment of anaphylaxis.
In case of infusion reactions, the infusion is interrupted. After the disappearance of symptoms of infusion reactions of mild to moderate severity according to NCI-CTC (general criteria for toxicity of the National Cancer Institute in the USA), the resumption of infusion is possible. In case of development of severe life-threatening infusion reactions, consideration should be given to discontinuing further therapy with Herceptin ®.

Information on selected adverse reactions is given below Infusion and hypersensitivity reactions It is estimated that about 40% of patients receiving Herceptin ® experience some form of infusion. 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 (but are not limited to) the following symptoms: chills, fever, rash, nausea and vomiting, shortness of breath and headache. Severe anaphylactic reactions requiring immediate additional medical intervention, most likely to occur during the first or second infusion of the drug Herceptin ®, such reactions were associated with a fatal outcome. Cardiotoxicity Cardiotoxicity (heart failure) NYHA Functional Class II-IV is a common adverse reaction with Herceptin ® and has been associated with a fatal outcome. In 3 basic clinical trials of the use of trastuzumab in combination with adjuvant chemotherapy, the frequency of cardiac dysfunction of 3/4 degree (symptomatic congestive heart failure) did not differ from that in patients receiving only chemotherapy (i.e., without Herceptin ®), and in patients receiving taxanes and Herceptin ® sequentially (0.3-0.4%). The frequency was greatest in patients receiving Herceptin ® together with taxanes (2%). The safety of continuing or resuming therapy with Herceptin ® in patients experiencing cardiotoxicity has not been studied prospectively. However, the status of most patients who experienced heart failure in baseline studies improved with standard therapy, which included diuretics, cardiac glycosides, beta-blockers, and / or ACE inhibitors. Most patients with cardiac symptoms and signs of clinical benefit from Herceptin ® therapy continued therapy without additional clinically significant cardiac events. Experience with Herceptin ® in combination with low-dose anthracycline regimens in neoadjuvant therapy is limited. Hematologic toxicity Very often febrile neutropenia occurred. Adverse reactions that frequently occur include anemia, leukopenia, thrombocytopenia, and neutropenia. The incidence of hypoprothrombinemia is unknown. The risk of neutropenia may be slightly higher when using trastuzumab in combination with docetaxel after treatment with anthracycline drugs. Lung disorders Herceptin ® is associated with severe adverse events in the lungs (including fatal outcomes). These reactions include (but are not limited to): lung infiltrates, acute respiratory distress syndrome, pneumonia, pneumonitis, pleural effusion, acute pulmonary edema, and respiratory failure. Drug Interaction No specific human drug interaction studies have been conducted with Herceptin ® in humans. In clinical studies, no clinically relevant interaction with concomitantly administered drugs (including doxorubicin, paclitaxel, docetaxel, capecitabine or cisplatin) was noted. Herceptin ® is not compatible with 5% dextrose solution due to the possibility of protein aggregation. Herceptin ® cannot be mixed or dissolved with other medicines. No incompatibilities were observed between the solution of Herceptin ® and infusion bags made of polyvinyl chloride, polyethylene or polypropylene. overdose No clinical overdose of drug was observed. The administration of the drug Herceptin ® in single doses greater than 10 mg / kg has not been studied. Herceptin ® at doses of 10 mg / kg was well tolerated.
