L.01.B.A.04 Pemetrexed

Pharmacodynamics:Pemetrexed is a folic acid antagonist acting on many targets of its metabolism and inhibiting in vitro thymidylate synthase (TS), dihydrofolate reductase (DHFR), glycine aminobonucleotide transformant transferase (GARFT), which are key folate-dependent enzymes in the biosynthesis of thymidine and purine nucleotides. Pemetrexed enters the cells with the help of a carrier of reduced folates and protein folate-binding transport systems. Entering the cage, pemetrexed quickly and effectively converted into polyglutamate forms with the help of the enzyme folyl polyglutamate synthetase. Polyglutamate forms are retained in cells and are more potent inhibitors of TS and GARFT. Polyglutamination is a process dependent on time and concentration, which occurs in tumor cells and to a lesser extent in normal tissues. In poliglutaminirovannyh metabolites the half-life is increased, owing to what the action of a preparation in tumor cells increases.
With the combined use of pemetrexed and cisplatin, an antitumor effect was observed in in vitro studies.

Pharmacokinetics:The constant volume of distribution of pemetrexed is 9 l / m2. About 81% of pemetrexed binds to plasma proteins. Binding is not impaired in severe renal failure. Pemetrexed is limitedly metabolized in the liver.
From 70 to 90% of the drug is excreted by the kidneys unchanged in the first 24 hours after administration.The total plasma clearance of pemetrexed is 92 ml / min, and the half-life from plasma is 3.5 hours in patients with normal renal function.

Indications:- Locally or metastatic non-cell lung non-small cell lung cancer;
- Malignant pleural mesothelioma.

Contraindications:- Hypersensitivity to pemetrexed or excipients included in the preparation;
- Myelosuppression (absolute number of neutrophils <1500 / μl, platelets <100,000 / μl);
- Severe renal insufficiency (creatinine clearance (CK) <45 ml / min);
- Pregnancy, lactation;
- Child age (lack of safety and efficacy data);
- Simultaneous use with a vaccine to prevent yellow fever.

Carefully:- If the liver function is impaired;
- In severe diseases of the cardiovascular system, including myocardial infarction and cerebral circulation disorders.

Pregnancy and lactation:contraindicated

Malignant pleural mesothelioma

Combined treatment with cisplatin:

The recommended dose of ALIMTA® is 500 mg / m² on the first day of each 21-day cycle.

Cisplatin is administered at a dose of 75 mg / m against hydration (see instruction on the use of cisplatin) approximately 30 minutes after administration of ALIMTA® on the first day of each 21-day cycle.

Recommendations before starting the use of the drug ALIMTA®

The administration of dexamethasone (or analogue) at a dose of 4 mg 2 times a day, 1 day before the start of treatment with pemetrexed, on the day of administration and the day after administration of pemetrexed reduces the frequency and severity of skin reactions.

To reduce the toxicity of the drug to patients receiving pemetrexed, preparations of folic acid or multivitamins containing folic acid, providing its daily requirement, should be prescribed. Folic acid (from 350 μg to 1000 μg, an average of 400 μg) should be given for at least 5 days for 7 days before the first administration of pemetrexed, during the entire treatment cycle and for 21 days after the last administration of pemetrexed. Patients also need to once inject vitamin B12 at a dose of 1000 μg intramuscularly for 7 days before the first injection of pemetrexed and then every 3 cycles after the start of treatment. The subsequent administration of vitamin B12 at the same dose can be performed on the day of administration of pemetrexed.

Observation

For all patients receiving pemetrexed, it is recommended to observe before each injection of the drug for a general clinical analysis of blood, including the definition of the leukocyte formula and the number of platelets.To assess the function of the kidneys and liver, a biochemical blood test should be performed before each injection of pemetrexed. Before the beginning of each cycle of chemotherapy, the absolute number of neutrophils (ACH) should be> 1500 cells / mm³, the number of platelets -> 100000 cells / mm³, the concentration of the total bilirubin - <1.5 times the upper limit of the norm (HHV), alkaline phosphatase, aspartic and alanine aminotransferases <3 times of IGN, or <5 times of IGN in the presence of metastases in the liver.

Recommendations for dose reduction. Dose adjustment before repeated cycles should be carried out, based on the lowest of the hematological parameters or at the most pronounced non-hematologic toxicity during the previous treatment cycle. Treatment can be delayed in order to recover from manifestations of toxicity. As treatment is restored, treatment should be continued in accordance with the recommendations in Tables 1-3, which relate to the use pemetrexeda in monotherapy or in combination with cisplatin.

Hematological toxicity	Correction dose (mg / m²)
The minimum neutrophil count <500 / μL and the minimum platelet count> 50,000 / μL	75% from previous doses (pemetrexed and cisplatin)
The minimum platelet count <50,000 / μl, regardless of the minimum neutrophil count	75% from previous doses (pemetrexed and cisplatin)

^a These criteria are consistent with the definition bleeding> = 2 according with the criteria of general toxicity National Cancer Institute (NCI-CTC).

With the development of non-hematological toxicity (excluding neurotoxicity) > = 3 degrees, treatment is necessary defer to restoration of indicators, corresponding to the value before the start of treatment. Further therapy should be continued in accordance with the recommendations given in Table 2.

Treatment pemetrexed should be discontinued if the patient has hematologic and non-hematologic toxicity grade 3 or 4 after two decreases in doses or immediately reversed if neurotoxicity is 3 or 4 degrees.

Special patient groups

Elderly Patients: Data on The risk of side effects in patients 65 years of age or older is absent. Reduction mode doses meet the general recommendations.

Patients with impaired renal function: At QC values of at least 45 ml / min, dose adjustment and administration of the drug is not required.Patients with SC less than 45 ml / min pemetrexed is not recommended (due to insufficiency of data on the use of the drug in this category of patients).

Patients with impaired hepatic function: Insufficient data on the use of the drug in patients with impaired liver function with an excess of bilirubin concentration is more than 1.5 times the upper limit of the norm (UGN), or the excess of aminotransferase activity is more than 3 times that of UGH (in the absence of metastases in the liver), or more than 5 times from VGN (in the presence of metastases in the liver).

Recommendations for the preparation of a solution for infusions

1. Only 0.9 is used as a solvent % solution of sodium chloride.

2. For the preparation with a dosage of 100 mg: to obtain a solution for infusions, the contents of the vial (100 mg) are dissolved in 4.2 ml of 0.9% sodium chloride solution (without preservatives) 25 mg / ml (approximately). Each vial is gently shaken until completely dissolved lyophilisate.

The resulting solution should be clear; it is permissible to change the color of the solution from colorless to yellowish or greenish-yellow in color.

3. The corresponding volume of the obtained pemetrexed solution must be further diluted to 100 ml 0.9 % solution of sodium chloride.

4. Before administration, the drug solution should be inspected for particles and discoloration.

The solution for administration should be used immediately or within 24 hours if stored at 2-8 ° C, since pemetrexed and the recommended solvent not contain antibacterial preservatives. Unused solution must be disposed of.

Also, cases of pancytopenia, esophagitis / radiation esophagitis were reported infrequently.
In rare cases, the development of hepatitis, a potentially severe degree, was noted. In applying pemetrexed cases of colitis (including rectal and intestinal bleeding. Sometimes fatal, perforation of the intestinal wall, bowel necrosis and inflammation of the caecum) were recorded and interstitial pneumonitis with respiratory failure, sometimes fatal (infrequently).
According to the results of clinical studies, approximately 1% of patients reported development of sepsis, in some cases with a fatal outcome.
Post-marketing data:
Infrequent - edema, limb ischemia, in some cases with the development of necrosis, acute renal failure, radiation pneumonitis; rarely - in patients previously receiving radiation therapy, there were cases of repeated development of skin reactions similar to radiation (anamnestic reaction to irradiation) with the subsequent appointment of pemetrexed; cases of bullous dermatitis have also been reported,including Stevens-Johnson syndrome and toxic epidermal necrolysis, in some cases fatal; rarely reported cases of development of hemolytic anemia, anaphylactic shock.

Overdose:Expected complications of an overdose include oppression of bone marrow function, manifested by neutropenia, thrombocytopenia and anemia. Secondary infections, diarrhea, inflammation of the mucous membranes, rash may also occur.
In case of suspicion of an overdose of the drug should be regularly monitored by a general blood test. Treatment: symptomatic, including the immediate use of calcium folinata or folinic acid.

Interaction:In vitro studies have shown that pemetrexed is actively secreted by OAT3 (a carrier of organic anions of human type 3).
Joint use with nephrotoxic drugs (such as aminoglycosides, looped diuretics, platinum-containing drugs, ciclosporin) and / or substances released by the kidneys through tubular secretion (eg, probenecid) can lead to a decrease in the clearance of pemetrexed.The results of in vitro studies indicate that pemetrexed minimally interacts with drugs that are metabolized by CYP3A isoenzymes. CYP2D6. CYP2C9, CYP1A2.
The pharmacokinetics of pemetrexed does not change when folic acid is administered orally. vitamin B12 intramuscularly and with combined use with cisplatin. The total clearance of platinum derivatives is not impaired by the use of pemetrexed.
The use of non-steroidal anti-inflammatory drugs (NSAIDs) in high doses (eg, ibuprofen more than 1600 mg / day or acetylsalicylic acid more than 1,300 mg / day) concomitantly with pemetrexed therapy even in patients with normal kidney function (CC> 80 mL / min) may lead to reduce the clearance of pemetrexed and enhance its side effect.
Patients with mild and moderate renal insufficiency (CK 45-79 ml / min) are not recommended to use NSAIDs with a short half-life for 2 days before applying pemetrexed, on the day of application and for 2 days after applying pemetrexed.
In view of the lack of data on the possible interaction between pemetrexed and NSAIDs with a long half-life (piroxicam, rofecoxib), patients with mild or moderate renal failure receiving NSAIDs. should stop their use at least 5 days before the administration of pemetrexed, on the day of administration and within 2 days after the administration of pemetrexed. If the combined use of NSAIDs is required. patients need strict monitoring of toxicity, especially myelosuppression and toxicity from the gastrointestinal tract (GI tract).
Pemetrexed is incompatible with Ringer's lactate solution and Ringer's solution. The combined use of pemetrexed with other drugs and solutions has not been investigated, and therefore is not recommended (with the exception of 0.9% sodium chloride solution).
When used simultaneously with live attenuated vaccines, it is possible to intensify the process of replication of the vaccine virus, increase its side / adverse effects and / or reduce the production of antibodies in the patient's body in response to the introduction of the vaccine.
When used simultaneously with oral anticoagulants, the International Normalized Ratio (INR) should be monitored regularly.

Special instructions:The drug ALIMTA® should be used under the supervision of a doctor who has experience in the use of antitumor drugs. Myelosuppression is the dose-limiting toxicity of pemetrexed.
Before each introduction of pemetrexed, it is necessary to perform a general blood test with counting the leukocyte formula and the number of platelets.
To assess the function of the kidneys and liver, it is necessary to periodically perform a biochemical blood test.
Before using the drug, the absolute amount of neutrophils should be> 1,500 in μL, platelets> 100,000 in μL.
The administration of folic acid and vitamin B12 reduces the toxicity of pemetrexed and the need for dose reduction for hematological and nonhematological toxicity of 3/4 degree, such as neutropenia, febrile neutropenia and infection with neutropenia of 3/4 degree.
The administration of dexamethasone (or its analogue) at a dose of 4 mg 2 times / day 1 day before the start of treatment with pemetrexed, on the day of administration and the day after administration of pemetrexed reduces the frequency and severity of dermatological reactions.
The effect of the presence of effusion in the serous cavities (ascites or pleurisy) on the action of pemetrexed is not completely known.In patients with effusion in serous cavities in a stable state, there was no difference in the concentrations of pemetrexed in plasma injected in a standard dose, or its clearance compared to patients without such effusion. Thus, the possibility of draining the effusion before starting treatment with pemetrexed should be considered, but this is not a prerequisite. During the treatment with pemetrexed and at least 6 months after it is necessary to use reliable methods of contraception.

Effect on the ability to drive transp. cf. and fur:The influence of pemetrexed on the ability to drive vehicles has not been studied. but pemetrexed can cause fatigue, so patients who have increased fatigue, it is not recommended to drive vehicles and engage in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
