What is Afinitor?

It is a medicine used in the treatment of cancer.

What does Afinitor contain and how does it work?

The active substance is everolimus, an anti-cancer drug from the group of protein kinase inhibitors. Protein kinases are enzymes that phosphorylate other proteins in the cell and thereby regulate their activity. In normal cells, the activity of protein kinases is strictly regulated, while in cancer cells it often gets out of control and is excessive. This causes disturbances in the functioning of many cellular pathways, and consequently leads to increased cell division and uncontrolled tumor growth. Inhibition, i.e. inhibition of excessive protein kinase activity, is the therapeutic target of the group of anticancer drugs in question. Everolimus inhibits mTOR protein kinase activity. This kinase not only controls cell division but also controls the synthesis of HIF transcription factors regulating the ability of the tumor to adapt to oxygen deficiency conditions and to the production of the factor responsible for the formation of tumor vasculature (vascular endothelial growth factor VEGF). Inhibition of mTOR kinase activity by everolimus not only limits the division of tumor cells but also reduces the level of HIF and VEGF proteins in the tumor or its environment which inhibits the development of tumor vasculature (anti-angiogenic effect). Used in the treatment of renal cell carcinoma.

When to use Afinitor?

The preparation is indicated for the treatment of patients with advanced renal cell carcinoma, whose disease progression occurred during or after anti-VEGF therapy (against the factor of vascular endothelial growth).

When not to use this preparation?

Unfortunately, even if there are indications to use the preparation, it can not always be used. You can not use the preparation if you are allergic (you are hypersensitive) to any of the ingredients of the preparation or to derivatives of rapamycin (sirolimus). Do not use during pregnancy. The use of the preparation is contraindicated during breast-feeding.

When should you use extreme caution when using Afinitor?

Certain diseases and other circumstances may constitute a contraindication to use or indication to change the dosage of the preparation. In certain situations, it may be necessary to carry out specific check-ups. Treatment may only be conducted under the supervision of an oncologist who has experience in the use of anticancer medicines.
Before and during the treatment, your doctor will prescribe lung X-ray examinations. The use of the preparation is associated with the risk of interstitial pneumonia or other forms of non-infectious pneumonia (non-infectious forms). Interstitial pneumonitis can be severe and in some cases can lead to death. Symptoms may include: shortness of breath, cough, fever, pleural effusion, hypoxia. If new or worsening respiratory symptoms occur, please consult your doctor immediately.Sometimes the severity of symptoms may require discontinuation of the preparation and treatment with corticosteroid s.
The preparation has an immunosuppressive effect, which means that it inhibits the immune response of the body. Therefore, the risk of bacterial, viral, fungal or protozoal infections, including opportunistic infections, increases. Infections may be local or systemic. Some of them may have a severe course and can lead to death. Before starting treatment, all existing infections should be cured. Any symptoms suggestive of infection should be immediately consulted with a doctor who will recommend appropriate treatment and if necessary discontinue administration.
The preparation may cause hypersensitivity reactions, including life-threatening Anaphylactic reactions . Symptoms may include: flushing, redness of the face, chest pain, shortness of breath, angioneurotic edema (swelling of the tongue, swelling of the airways that impede breathing). If you experience the first symptoms of the above hypersensitivity reactions, seek medical attention immediately.
The preparation may cause ulcers and oral inflammation. Local treatment is recommended; do not use mouthwash containing alcohol or hydrogen peroxide because they can exacerbate the symptoms. Antifungal drugs can only be used on the order of a doctor and only if a fungal infection has been diagnosed.
Your doctor will recommend periodic tests of kidney function, including blood urea and creatinine. The preparation may cause kidney problems, which may be supported by a decrease in the rate of creatinine excretion and its elevated concentration in the blood.
Your doctor will recommend regular blood Glucose tests (on an empty stomach). Treatment may lead to increased blood glucose which may require the use of antidiabetic agents (insulin or other hypoglycaemic agents). The first symptoms of an increase in blood glucose may be an increased thirst or an increase in urine volume and frequency of donation. If the above symptoms occur, please consult your doctor immediately.
Your doctor will prescribe a blood lipid control test before and during your treatment. During the treatment period, increased levels of triglycerides and cholesterol in the blood (hyperlipidemia, hypercholesterolemia) may occur, which may require appropriate treatment.
Your doctor will recommend regular haematological tests during your treatment because there is a risk of neutropenia (decreased neutrophil counts), lymphopenia (decreased lymphocyte counts), anemia and thrombocytopenia. Patients with thrombocytopenia are more likely to have haemorrhages (eg nosebleeds).
Hepatic impairment may increase exposure to everolimus. The preparation should not be used in patients with severe hepatic impairment.
Patients who are preparing for a major surgical procedure or in the perioperative period should be cautious, due to possible adverse effects of the preparation on the wound healing process. You should consult a doctor who will decide whether to stop treatment and possibly specify the time of cessation and the time to restart the treatment.
During the treatment period, the use of vaccines containing live microorganisms should be avoided, due to the risk of developing a serious vaccine reaction. Vaccination with other vaccines may be less effective due to the weakened immune response.
The use of preparations that strongly stimulate or inhibit the activity of the cytochrome P450 3A4 isoenzyme or P-glycoprotein (see below, where drug interactions with other drugs are discussed) should be avoided as they can cause a dramatic change in the concentration of everolimus and its metabolites in the blood.
The preparation may cause fertility problems. The preparation used during pregnancy may be toxic to the fetus and may cause birth defects in newborn babies.
Persons being treated with the preparation (both men and women) should absolutely consult a doctor about the use of effective contraception to prevent pregnancy during the treatment period.
Additional information about the other ingredients of the preparation:
The preparation contains lactose; people with galactose intolerance, lactase deficiency or malabsorption of glucose-galactose should not use this preparation.

The preparation is contraindicated during breast-feeding.

Can I use other preparations in parallel?

Tell your doctor about all medicines you have recently taken, including those that are over the counter.
Everolimus is metabolised by the cytochrome P450 3A4 isoenzyme and therefore preparations that strongly inhibit the activity of this isoenzyme (such as ketoconazole, posaconazole, itraconazol, voriconazole, nefazodone, ritonavir, atazanavir, nelfinavir, telithromycin, Clarithromycin ) may increase the concentration of everolimus and its metabolites in the blood and they may increase exposure (exposure) to everolimus; therefore, the use of these preparations is not recommended in parallel. The parallel use of agents moderately inhibiting CYP3A4 activity (such as Erythromycin , diltiazem, Verapamil , oral cyclosporine, Fluconazole , amprenavir, fosamprnavir) can only be undertaken with extreme caution. In addition, if you can not avoid using these medicines in parallel, your doctor may reduce the dose. Avoid consumption of grapefruit juice, which also inhibits CYP3A4 activity.
Drugs that potentiate the activity of the cytochrome P450 3A4 isoenzyme (such as rifampicin, Dexamethasone and other corticosteroids, phenytoin, carbamazepine, phenobarbital, efavirenz, nevirapine, St. John's wort) may reduce the concentration of everolimus and its metabolites in the blood and reduce the exposure to everolimus and its efficacy. actions; therefore, the use of these preparations is not recommended in parallel.
Caution should be exercised when using everolimus with drugs metabolised by the 2D6 isozyme (eg desipramine) or 3A4 cytochrome P450 because their concentration in blood may change as a result of changes in the activity of these isoenzymes.
Parallel administration of everolimus and drugs transported by P-glycoprotein may cause interaction.Everolimus may affect the blood concentration and the severity of side effects of the following drugs (and other substances transported by P-glycoprotein): vincristine, colchicine, Paclitaxel , Digoxin ; be careful.
During the treatment period, the use of live vaccines (eg nasal influenza vaccine, measles vaccinations, mumps, rubella, oral polio vaccine, BCG, yellow fever, chickenpox and typhoid fever [TY21]) should be avoided. Other vaccinations may be less effective due to the weakened immune response.

What side effects can occur?

Like all medicines, Afinitor can also cause side effects, although they will not occur in all patients who use this medicine. Remember that the expected benefits of using the drug are usually greater than the damage resulting from the occurrence of side effects.
